The objective of this work was to evaluate the addition of carbaubeira fruit meal (CFM) to replace corn, on the performance and carcass yield of European quails. Initially, the bromatological analysis of the CFM, was performed to determine the percentage of inclusion of it in the experimental diets. Six hundred, one day old, male and female European quails, were distributed in a completely randomized design composed of five treatments (increasing levels of corn substitution by CFM being 0, 4, 8, 12 and 16 % of inclusion), eight repetitions and 15 birds per repetition. Weekly, from 1 to 42 days of age, feed intake (FI), weight gain (WG) and feed conversion (FC) were evaluated. At 42 days after slaughter, slaughter weight, weight of noble cuts (breast and thighs) and organs (gizzard, cecum and small intestine) were determined. The data were subjected to analysis of variance and the means that showed a significant difference were compared using the Tukey and Dunnet tests (P

The use of betaine associated or not with choline chloride 70% in Japanese quail diets in the laying phase was evaluated. 504 Japanese quails (Coturnix cortunix Japonica) were used from 104 to 208 days old, in a 3x2 + 1 factorial design, completely randomized design, seven treatments, nine replications, eight birds per experimental unit. Betaine was supplemented in 20% of the digestible methionine level of the control diet, in diets with reformulated betaine the level of enrichment was in the nutritional matrix of the product (100%) and with an extra recovery of 5% (105%). Choline chloride was fixed at 0.07%. Productive performance, egg quality, histometry, and the number of goblet cells from the duodenum and hepatic glycogen were analyzed. The use of betaine promoted greater weight of the eggs to the control, regardless of the mode of use, the use of choline promoted a superior result in the weight of the eggs. In egg quality, only shell percentage was influenced. The use of the reformulated betaine 100% of the matrix promoted greater height of the villi, and a lower villus: crypt ratio to the treatment with the reformulation enriched by 105%. Hepatic glycogen was not influenced. In goblet cells, the reformulation in an extra 105% of the matrix was superior to the matrix in 100%. The hill reduced villus height, improved villus: crypt ratio, and number of goblet cells. In conclusion, the reformulated betaine enriched in an additional 5% of its nutritional matrix replaces the use of choline chloride in the laying of Japanese quail diets. Se evaluó el uso de betaína asociada o no con cloruro de colina al 70% en dietas de codorniz japonesa en la fase de puesta. Se utilizaron 504 codornices japonesas (Coturnix cortunix Japonica) de 104 a 208 días de edad, en un diseño factorial 3x2 + 1, diseño completamente al azar, siete tratamientos, nueve repeticiones, ocho aves por unidad experimental. La betaína se complementó en un 20% del nivel de metionina digerible de la dieta de control, en las dietas con betaína reformulada el nivel de enriquecimiento se encontraba en la matriz nutricional del producto (100%) y con una recuperación adicional del 5% (105%). El cloruro de colina se fijó al 0,07%. Se analizó el rendimiento productivo, la calidad del huevo, la histometría y el número de células caliciformes del duodeno y el glucógeno hepático. El uso de betaína promovió un mayor peso de los huevos al control, independientemente del modo de uso, el uso de colina promovió un resultado superior en el peso de los huevos. En la calidad del huevo, solo el porcentaje de cascarón fue influenciado. El uso de la betaína reformulada al 100% de la matriz promovió una mayor altura de las vellosidades, y una relación vellosidad: cripta más baja al tratamiento con la reformulación enriquecida en un 105%. El glucógeno hepático no fue influenciado. En las células caliciformes, la reformulación en un 105% adicional de la matriz fue superior a la matriz en un 100%. La colina redujo la altura de las vellosidades, mejoró la relación vellosidad: cripta y el número de células caliciformes. En conclusión, la betaína reformulada enriquecida en un 5% adicional de su matriz nutricional reemplaza el uso de cloruro de colina en la colocación de las dietas japonesas de codorniz. Avaliou-se o uso da betaína associada ou não com cloreto de colina 70% em rações de codornas japonesas na fase de postura. Foram utilizadas 504 codornas japonesas (Coturnix cortunix Japonica) de 104 a 208 dias de idade, em esquema fatorial 3x2+1, delineamento inteiramente casualizado, sete tratamentos, nove repetições, oito aves por unidade experimental. A betaína foi suplementada em 20% do nível de metionina digestível da dieta controle, nas dietas com betaína reformulada o nível de enriquecimento foi da matriz nutricional do produto (100%) e com valorização extra de 5% (105%). O cloreto de colina foi fixado em 0,07%. Analisou-se desempenho produtivo, qualidade de ovos, histometria e número de células caliciformes do duodeno e glicogênio hepático. O uso da betaína promoveu maior peso dos ovos em relação ao controle, independentemente do modo de uso, o uso da colina promoveu resultado superior no peso dos ovos. Na qualidade dos ovos, somente percentual de casca foi influenciado. O uso da betaína reformulada 100% da matriz promoveu maior altura dos vilos, e menor relação vilo:cripta em relação ao tratamento com a reformulação enriquecida em 105%. O glicogênio hepático não foi influenciado. Nas células caliciformes, a reformulação em 105% extras da matriz foi superior a matriz em 100%. A colina reduziu altura dos vilos, melhorou relação vilo:cripta e número de células caliciformes. Em conclusão, a betaína reformulada enriquecida em mais 5% de sua matriz nutricional substitui o uso de cloreto de colina nas rações de codornas japonesas em postura.

The Japanese quail (Coturnix coturnix japonica) rearing activity has grown considerably over the past few years. The purpose of this study was to compare diet formulations based on total (TAA) and digestible amino acids (DAA) and the use of different protein sources such as meat cum bone meal and feather meal in Japanese quails. The first three treatments were based on TAA, formulated based on corn and soybean meal (CST); meat and bone meal (CSMT); feather meal (CSMFT). The three other treatments received the same sequence of ingredients as the previous treatments; however, the diets were formulated based on digestible amino acids (DAA) (CSD, CSMD, and CSMFD). The results show that the base of diet formulation improves the performance of quails from 1-21d and the quails show that is possible to replacement of soybean meal with animal-origin by-products such as meat bone meal and feather meal, buts is needed to evaluate more aspects. In conclusion, diets formulated base on DAA for Japanese quails can be utilized with the same efficiency as diets based on TAA.
