The objective of this study was to verify the association of improved native grassland and winter and summer pastures on the weaning rate in beef cattle production. Subsequently, we also verified the socioeconomic and productive characteristics related to the adoption of technologies to increase the weaning rate of the farmers. The survey was conducted with 73 producers of Hereford and Braford cattle in the state of Rio Grande do Sul, Brazil. A data analysis was performed using the minimum ordinal squares method and the regression analysis (Tobit). The results showed that cattle farmers who adopt winter pastures have greater weaning rates, and the factors that influence this adoption are related to a greater number of employees on the farm and the use of a crop-livestock production system. In addition, farmers who receive a greater number of technical assistance visits per year are more likely to adopt winter pastures and improved native grassland. This information can be useful in the formulation of technological dissemination programs that aim at a sustainable production of beef cattle.

We investigated the ability to predict production performance in Iberian pigs in an extensive production system from measurements of feed efficiency measured intensively. The second objective of this work was to study the relationship between feed efficiency and meat quality (composition, juiciness, tenderness, color, and subcutaneous fatty acid composition) and if cooked and cured quality properties can be predicted by properties in fresh meat. Thirty Iberian sows received successively a restricted diet of concentrate (P1concentrate) and acorns (P2acorn) intensively and an ad libitum diet of acorns supplemented with a restricted amount of concentrate (P3montanera) extensively. Pigs that were more feed efficient on concentrate were less feed efficient on acorns and had higher body weight gain during the montanera . Improved feed efficiency on acorns reduced the concentration of α-linolenic and linoleic fatty acid composition of subcutaneous fat. Faster body weight gain in montanera resulted in a desirable reduction in cooking loss and a reduction in palmitic acid content in subcutaneous fat, and a potentially undesirable reduction in meat redness. Tenderness in cooked or cured loin was not significantly related to tenderness in the raw product. Cooking loss was positively related to purge and centrifugal drip loss and to color coordinates a*24 and b*24 in raw samples. We conclude that feed efficiency and body weight gain may be improved in the traditional Iberian production system, with a positive effect on cooking loss but potentially resulting in paler meat.

The objective of this study was to identify types of production system and their main indicators on bioeconomic efficiency, using qualitative and quantitative methods to evaluate beef cattle farms in the western region of the state of Rio Grande do Sul. A survey was carried out with 43 farmers operating in the western region of that state. All farms operated with complete cycle production systems in areas larger or equal to 900 ha. A qualitative questionnaire with binary answers and a quantitative questionnaire with numerical answers were applied. Technology and Management drivers were used for the calculation of the efficiency index of farmers obtained by both questionnaires. Farmers were divided into three clusters: low-efficiency level (LEL), intermediate-efficiency level (IEM), or high-efficiency level (HEL), as a result of the comparison of the scores obtained for the analyzed parameters. Subfactors resulting from each comparison (LEL × IEL; LEL × HEL, and IEL × HEL) were different as a function of the comparison and of the methods applied. Low-efficiency level farmers need to improve essential production processes, such as technology and management, as well as health management practices together with the financial management of the production system. Intermediate-efficiency level farmers need to improve their routine animal management, pasture management, and calculation of financial indicators to become highly efficient. The quantitative method allowed to identify underestimation (39.3%) or overestimation (24.2%) when farmers were are classified in clusters. Different methods may be used, but those based on quantitative information have stronger discrimination power to identify different types of farmers.

This study aimed to characterize the current production system of the Bísaro pig breed. Between February and April 2017, 194 questionnaires covering different aspects of the system were sent as a disclosed identity mail survey. A response rate of 31.4% was obtained. The typical Bísaro farmer is 46 years old, male, has five years of experience rearing pigs, and has a secondary or higher education degree. Piglets represented the majority of animals sold for slaughter (91.1%) and constituted 41.1% of total Bísaro meat produced with 343 tons. The majority of producers differentiate feed per production group (79.3%) and allow grazing (73.7%). Feeding is usually complemented with own-farm crops (94.7%). Traditional housing system remains the most common (52.6%), but free-range camping systems had a considerable expression (40.4%). All year-around farrowing system (91.2%) without heat detection (65.5%) and limited use of artificial insemination (12.5%) characterized the reproduction management. Males are commonly castrated at 29 days, before weaning at 35 days. Categorization of farms showed some significant differences: smallholders (n = 33) belonged to a single producer, had family-based work, and reproductive management was predominantly less strict; non-industrial medium-sized holdings (n = 26) operated as commercial-based farms with larger production, greater farm areas, and more advanced technology. Although the survey demonstrated variability within farms, Bísaro production system was characterized, and two different types of farms were identified. This study provided the tools needed to discuss and revise some management practices, mainly those that revealed noncompliance with EU regulations, to enhance consistency of Bísaro products.

This work was aimed to identify the typology and the characteristics of the goat milk production systems. Seventy rural properties were researched. Multivariate data analysis with cluster formation techinique was used, and also the identification of five different groups of production systems. The production systems were classified through technical and economical efficiency, ranking groups 1 and 2 as high technological level, groups 3 and 4 as medium level, and the group 5 as low level. The high technological level systems used practices of more rational handling with larger technological employment becoming better specialized. These systems present the largest revenues of milk and unitary net profit. Medium technological production systems adopt technological recommendations and look for alternatives of handling practices. Production system 1 adopts intensive sanitary practices for the farmyard facilities and stables, but this does not happen in the production system 2. Vermifuge is applied three times a year in system 1 while in the system 2 it is applied twice a year. The producers of the systems 1 and 2 obtain more financial resources through official credit lines, and the producers of the group 2 are more punctual on the pay off deadlines. Objetivou-se identificar a tipologia e as características dos sistemas de produção de leite de cabra. Foram pesquisadas 70 propriedades agrárias. A técnica utilizada foi análise multivariada com a formação de cluster, com identificação de cinco diferentes grupos de sistemas de produção. Os sistemas de produção foram tipificados pela eficiência técnica e econômica, como grupos 1 e 2, considerados de nível tecnológico alto, grupos 3 e 4, de nível médio, e grupo 5, de nível baixo. Os sistemas de nível tecnológico alto adotam práticas de manejo mais racionais com maior emprego tecnológico e são os mais especializados. Esses sistemas conferem as maiores receitas de leite e lucro líquido unitário. Os sistemas de produção de nível tecnológico médio adotam recomendações tecnológicas e buscam alternativas de práticas de manejo. Produtores do sistema de produção 1 utilizam práticas sanitárias intensivas das instalações de apriscos e currais para práticas mais alternadas realizadas no sistema de produção 2. O número de aplicações de vermífugo no sistema 1 é de três vezes ao ano, enquanto no sistema produtivo 2 é de duas aplicações. Os produtores dos sistemas 1 e 2 são os que mais captam recursos monetários por linha de crédito oficial, e os do grupo 2 os que mais se apresentaram com o financiamento quitado ou em dia.

O objetivo neste trabalho foi evidenciar a importância do custo de produção na pecuária de cria, descrevendo uma metodologia padronizada que consiga mensurar o custo de produção de bezerros de corte e, simultaneamente, validar o método em um sistema de produção. Dentro deste contexto, neste trabalho discute-se, inicialmente, a relevância da implantação da metodologia dos centros de custos como suporte à tomada de decisão, devido à necessidade de uma análise segmentada dos processos em sistemas de produção pecuários especializados na cria. As etapas para implantação deste método são descritas. Um sistema de produção, característico da Região Sul do Brasil, foi definido a partir de indicadores técnicos relatados em revisões bibliográficas. Foi simulada a aplicação desta metodologia no sistema em questão, no qual se visualizaram os custos de produção dos diferentes centros produtivos: touros, vacas de cria, recria das novilhas e desmame dos bezerros, possibilitando compreender o impacto de determinados processos e/ou tecnologias no sistema. Conseqüentemente, calcular o custo de produção de bezerros de corte a partir da utilização da metodologia dos centros de custos, mostrou-se factível de utilização em sistemas de produção baseados em pecuária de cria. The production cost in cow-calf was designed by a standard methodology that can be able to measure the production cost of calves and, simultaneously to validate the method in a production system. Within this context, the present paper discusses, initially, the relevance of the implementation of methodology in cost centers as a support decisionmaking, due to the need for a segmented analysis of the processes, specialized in cow-calf production systems. The stages for implementation of this method are described. A production system, typical of the Southern of Brazil, was defined from technical indicators reported in reviews. It was simulated the application of this methodology of the subjected system, where it was viewed the production costs of the different productive centers: bulls, cows, rearing of heifers and weaning of calves, enabling to understand the impact that determinates process and/or technologies bring on to the system. Consequently, to calculate the production cost of calves from the methodology based on the cost centers was feasible to be used in production systems based on cow-calf.

Foram utilizados 48 machos castrados de mesma linhagem genética, com pesos iniciais de 30,8 ± 0,12 kg (fase de crescimento) e 61,2 ± 0,89 kg (fase de terminação), segregados no sistema de produção. Os animais foram distribuídos em delineamento experimental de blocos ao acaso, compostos de quatro tratamentos (níveis de PB) e seis repetições e dois animais por unidade experimental. Os níveis de PB testados foram 19,5; 18,0; 16,5 e 15,0% na fase crescimento e 18,0; 16,5; 15,0 e 13,5% na fase terminação. Na fase crescimento, não foram constatadas diferenças no desempenho dos machos castrados. Independentemente do nível de PB na dieta, as exigências nutricionais foram atendidas, não obstante, a dieta com 16,5% PB indicou maior viabilidade econômica, calculada como margem bruta decorrente da alimentação. Semelhante à fase de crescimento, na fase de terminação os níveis de PB da dieta não promoveram diferenças no desempenho e nas características de carcaça dos animais ao abate. Ao considerar a margem bruta atribuída à alimentação, a dieta com 15,0% PB permitiria maior retorno econômico no período correspondente ao intervalo dos 60 aos 100 kg. A variação da proteína dietética com a suplementação dos principais aminoácidos não prejudicou o desempenho de suínos machos castrados nas fases de crescimento e terminação criados em condições desejáveis de saúde, segregados, em sistema de criação comercial. Pequenas variações entre aminoácidos não prejudicam o desempenho de suínos machos castrados nas fases de crescimento e terminação, desde que as exigências de lisina digestível e dos demais aminoácidos limitantes sejam mantidas próximas às relações mínimas atualmente indicadas. It was evaluated four crude protein (CP) levels in diets considered as commercial fed to barrows in the growing and finishing phases. A total of 48 barrows, from the same genetic strain, averaging initial weights of 30.8 ± 0.12 kg (growing phase) and 61.2 ± -0.89 kg (finishing phase), segregated in the production system, was used. The animals were allotted to randomized blocks design, composed of four treatment (level of CP) and six replications and two animals per experimental unit. The CP levels tested were: 19.5, 18.0, 16.5, and 15.0% in growing and 18.0, 16.5, 15.0 and 13.5% in finishing phases. There was no difference in the growing phase of barrows performance. Independently of the dietary CP levels, the nutritional requirements were supplied, in spite of the diet with 16.5% CP indicated greater economic viability, calculated as gross margin due to the feed. Similar to the growing phase, there were no differences among CP levels on performance and carcass characteristics of finishing barrows at slaughter. The gross margin due to the feed indicated that 15.0% CP in the diet offered greater economic gain for barrows from 60 to 100 kg. The results indicate that dietary protein changes, with main principal amino acids supplied not impaired the barrows performance. The creation and segregation conditions of commercial farm system in growing and finishing phases need considerations. Small variations between amino acids did not affect performance of barrows in the growing and finishing phases if the requirements of digestible lysine and others amino acids are maintained close to the indicated minimal relation.

Objetivou-se avaliar o desempenho e a variabilidade entre linhagens de avós de frangos de corte criadas em diferentes ambientes, considerando a interação genótipo x ambiente. Foram conduzidos 12 experimentos (quatro em ambiente de criação de frangos de corte, quatro em ambiente de criação sob condições de estresse e quatro em ambiente de granja de pedigree) utilizando-se 36.000 pintos (3.000 por experimento) de seis linhagens de avós de frangos de corte (quatro de linha fêmea e duas de linha macho), criados até a idade de 42 dias para avaliação de variáveis zootécnicas e morfométricas. Foram utilizados índices de conforto térmico (índice de temperatura e umidade e entalpia) para avaliação do microclima interno das instalações a que as aves foram expostas. Realizaram-se comparações de médias das características zootécnicas (peso vivo e rendimento de carcaça) e morfométricas (empenamento) das linhagens criadas nos diferentes ambientes. As respostas das linhagens para as características avaliadas variaram conforme o ambiente de criação utilizado. As linhagens da linha macho apresentaram maiores pesos vivos e rendimentos de carcaça eviscerada em comparação às da linha fêmea, que apresentaram melhor empenamento do dorso e da perna.

Foram utilizados 15 cordeiros inteiros, nascidos de partos simples, alimentados ad libitum com as rações experimentais duas vezes ao dia. Estimaram-se o consumo de médio diário de ração, pelo cálculo da quantidade fornecida e das sobras; o ganho de peso, pela pesagem dos animais a cada 14 dias; o peso vivo ao abate (PVA) dos cordeiros em jejum (16 horas); e o rendimento de carcaça quente, após abate e evisceração. O ganho médio diário foi influenciado pelos níveis de proteína, quando considerada a idade de abate como covariável. Não houve efeito significativo dos níveis de proteína sobre as características de carcaça. No sistema de alimentação e terminação de cordeiros Suffolk em creep feeding, a ração deve ser balanceada com 25% de proteína bruta, uma vez que esse nível proporcionou maior ganho de peso médio diário e não alterou as características de carcaça. This trial was carried out to evaluate the effects of different concentrate crude protein levels (15, 20 or 25%) on production and carcass traits of Suffolk lambs in creep feeding. An economical analysis of the production system was also performed. Fifteen single birth lambs fed ad libitum twice a day were used in this study. The average daily intake was measured by subtracting the orts from the amount of feed offered to the animals. Lambs were weighed every fourteen days to determine body weight gain. To measure slaughter body weight (SW) animals were fasted for 16 h and then weighted. After evisceration both hot carcass weight and yield were obtained. To determine cold carcass yield and cooling losses, carcasses were placed in a refrigerator at 5ºC for 24 hours and weighted again. The different concentrate crude protein levels affected the daily weight gain only when the slaughter age was used as the covariable. Conversely, crude protein levels did not significantly change carcass traits in the present trial. It can be concluded that the concentrate with 25% of crude protein is recommended to Suffolk lambs in creep feeding because of the higher daily weight gain and maintenance of carcass traits.

O objetivo deste trabalho foi avaliar o ganho em peso de novilhos em crescimento e terminação, o ganho de peso vivo por hectare e a qualidade da forragem em diferentes sistemas de produção a pasto, no inverno e verão. No inverno, foram avaliados sistemas de produção em pastagem de aveia preta (PAV) ou em grama estrela roxa (GER). No verão, foram avaliados sistemas de produção em pastagem de milheto (MIL), capim-Mombaça (MOM) ou grama estrela roxa (GER) e o efeito do sistema de produção utilizado no inverno sobre o desempenho animal no verão. No inverno, o sistema PAV propiciou maiores peso final (PF 381 kg), ganho médio diário (GMD 0,64 kg/dia) e ganho de peso vivo/ha (GPV/ha 233 kg), quando comparado ao sistema GER (PF 332 kg, GMD -0,01 kg/dia e GPV/ha -1,38 kg). Os animais mantidos no sistema PAV no inverno apresentaram menor desempenho no verão. Para os animais em crescimento, o sistema PAV no inverno e MIL no verão resultou em maior peso vivo final (447 kg) em relação aos sistemas PAV no inverno e MOM no verão (414 kg) e GER no inverno e MOM no verão (397 kg). Para os animais em terminação, não houve diferença no peso vivo final, no rendimento de carcaça e no peso de carcaça quente entre os sistemas avaliados. No inverno, a PAV e a GER apresentaram média de 15 e 5% de proteína bruta (PB), 51 e 81% de fibra em detergente neutro (FDN), 31 e 51% de fibra em detergente ácido (FDA) e 81 e 45% de digestibilidade in vitro da matéria seca (DIVMS). No verão, a GER, o MOM e MIL apresentaram média de 9, 9 e 18% de PB, 65, 64 e 54% de FDN, 40, 39 e 32% de FDA e 55, 60 e 80% de DIVMS.The aim of this work was to evaluate the weight gain of growing and finishing steers, the life weight gain per hectare, and the forage quality in different grass production systems in the winter and summer. In the winter, the black oat pasture (BOP) and star grass (SGA) production systems were evaluated. In the summer, the millet (MIL), Mombaça (MOM), and star grass (SGA) production systems were evaluated and the effect of the production systems used in the winter on the animal performance in the summer was evaluated too. In the winter, the BOP system resulted in higher final body weigh (FW 381 kg) higher average daily gain (ADG 0,64 kg/day) and higher life weight gain/ha (LWG/ha 233 kg) when compared with SGA system (FW 332 kg, ADG -0,01 kg/day and LWG/ha -1,38 kg). The animals kept on BOP system in the winter had lower performance in the summer. For the growing animals, the BOP in the winter and MIL in the summer resulted in higher final body weigh (447 kg) when compared with BOP in the winter and MOM in the summer (414 kg) and SGA in the winter and MOM in the summer (397 kg). For the finishing steers, there was no difference between the systems evaluated. In the winter, the BOP and SGA presented means levels of 15 and 5% of crude protein (CP), 51 and 81% of neutral detergent fiber (NDF), 31 and 51% of acid detergent fiber (ADF), and 81 and 45% of in vitro dry matter digestibility (IVDMD). In the summer, the SGA, MOM and MIL presented means levels of 9, 9, and 18% of CP, 65, 64, and 54% of NDF, 40, 39, and 32% of ADF, and 55, 60, and 80% of IVDMD.

Foi instalado um Sistema Intensivo de Suínos Criados ao Ar Livre (SISCAL), na Estação Experimental de Pato Branco do Instituto Agronômico do Paraná, com o objetivo de determinar os custos de implantação e produção deste sistema, na região Sudoeste do Paraná. A área do SISCAL foi dimensionada para um plantel de 14 matrizes e um reprodutor, a qual foi dividida em piquetes para separar os animais por estágios fisiológicos (reprodução, gestação e creche). O custo de implantação foi baseado nos custos de mão-de-obra e dos materiais utilizados para instalação do sistema e confecção de alguns equipamentos, como também os custos da construção da fábrica e depósito de ração e dos equipamentos para confecção das rações.O custo total de implantação do SISCAL, excluindo o valor da terra, foi de US$ 6862,80, ou seja, US$ 490,20 por matriz instalada, em julho de 1997. A construção e os equipamentos da fábrica de ração foram os itens mais caros do custo de implantação. O custo total de produção por kg de leitão desmamado produzido foi US$ 0,617, em junho de 1999. Neste período, foi possível obter 18,81% de lucro líquido por kg de leitão produzido. An Outdoor Pig Production System (SISCAL), at the Experimental Station Agronomic Institute of Paraná State was used with the objective to determine the establishment and production costs of this system in the Southwestern region of Paraná. The SISCAL area was dimensioned to a 14 sows and one boar herd, which was divided in paddocks to separate the animals per physiological stage (reproduction, gestation and nursery). The establishment cost was based on the labor, material used for the system installation and the manufacturing of some equipment, as well as the feed plant and storage construction costs and equipments for the ration production. The total establishment observed cost of the SISCAL, excluding capital value of land, was of US$ 6862.80 or US$ 490.20 per housed sow, in July 1997. The feed plant and storage construction costs as well as the equipments were the items that increased the establishment cost most. The production cost per kg of weaned pig was US$ 0.617 in June 1999. In this period it was possible to get an 18.81% of net income per kg of produced pig.

The objective of this research was to discern the contribution of genomic information to multiple-trait breeding objectives and thus understand the economic value of that information. True genetic values were simulated for each of n, possibly correlated, traits. These true genetic values, combined with uncorrelated random noise, resulted in both genomic and phenotypic estimated breeding values, EBVg and EBVp, respectively. The separate EBV were then merged (blended) as a function of their respective accuracies to produce a unified EBV for each of the n traits. Finally, for each simulated animal (N = 10000), the sum of products of economic weights and EBV was calculated to predict the economic value (net merit) of the individual. Accuracies of the EBV for the individual traits and net merit were calculated as correlations between predicted and true values. Predicted responses to selection for individual traits included in the breeding objectives were enhanced from 9% to 76% with the greatest benefit accorded to those economically relevant traits that are recorded after selection decisions are made at one year of age, measured less frequently in national cattle evaluation, or often predicted using information from indicator traits. Combining the EBV to predict net merit for terminal and maternal breeding objectives resulted in predicted increases in selection response due to incorporation of genomic information of 27% and 57%, respectively. The results are interpreted to suggest that the economic benefit to be derived from selection based on a multiple-trait economic breeding objective, which is predicted using genomically enhanced EBV, can substantially exceed the present day cost of genotyping the candidates for selection.
