1. This experiment determined the effect of increasing mobility in broiler chickens by placing barrier perches between feeders and drinkers. In addition, the limitation of early weight gain by dietary energy and protein dilution on some welfare parameters, tibiotarsus measurements, fear and mobility level was examined.2. A total of 504 male, one-day-old broiler chickens (Ross 308) were randomly allocated to four treatments with three replicate pens per treatment and 42 broiler chickens per pen as a 2 × 2 factorial arrangement. Treatments included feeding the basal control diet between 0-42 days or a diet diluted by 10% energy and 20% crude protein fed between 0-21 d, with the control diet fed between 22-42 d. The second factor was the presence or absence of barrier perches. All treatments were allocated as a completely randomised design. Welfare parameters (foot pad dermatitis, hock burn, gait score, feather score, breast blister), tibiotarsus measurements (bone mineral content, bone mineral density, fluctuating asymmetry and relative fluctuating asymmetry), tonic immobility and mobility level were recorded.3. Results showed that access to a barrier perch and the diluted diet increased the mobility in broiler chickens. However, access to a barrier perch had no significant effect on tibiotarsus and welfare parameters. Broiler chickens had better gait scores (P

Hygiene and sanitation, which are of great importance for the protection of human. Beside this quality and quantity of the milk is very important for human health. The aim of this project is to develop a training model in raw milk hygiene in Aydın province, and to increase knowledge, skills and competencies of vocational/professional groups in raw milk production. Two surveys were conducted for the farm workers to be trained within the scope of the project. Firstly, a demonstrative survey was conducted for the farms where milk hygiene training was provided. The education satisfaction survey was conducted for the people who were educated after the seminar. The surveys were prepared by the project executives and the questions were answered by face to face interview method. The milk samples of the study were collected from 157 dairy farm bulk tanks located in Aydin province, before the beginning of the project and after training courses. The milk samples were analyzed for Total Viable Count (TVC) and Somatic Cell Count (SCC). In conclusion, 11% of tank milk samples were below the norm value of 100000cfu/mL out of 157 farms. It is also seen that 27 farms reduced their SCC values below 400000cells/mL out of 56 farms with a norm value of ≥400000cells/mL after hygiene training. When the results were evaluated in general, hygiene was improved by 11% in average TVC value and 1% in SCC value after milking hygiene education.

Bu çalışma damızlık bıldırcın rasyonlarında nano selenyum (Se) kullanılmasının verim, canlı ağırlık artışı, yumurta kalite özellikleri, sperm kalitesi, kuluçka parametreleri ve karaciğer üzerine etkilerini belirlemek amacıyla yapılmıştır. Araştırmada 20 erkek ve 60 dişi olmak üzere toplam 80 adet 10 haftalık yaşta bıldırcın (Coturnix coturnix Japonica) kullanılmıştır. Hayvanlar kontrol (K - inorganik sodyum selenit) ve deneme (D - nano sodyum selenit) olmak üzere iki gruba ayrılmış, her grup altında da her biri bir (1) erkek üç (3) dişi içeren 10 adet alt grup oluşturulmuştur. Nano Se kullanılması verim, canlı ağırlık ve yem tüketimi üzerine herhangi bir önemli etki oluşturmamıştır. Ancak yumurta ağırlığı (P

An experiment was conducted to investigate the effects of lighting program, stocking density, and the provision of a perch on leg health variables as welfare indicators in broiler chickens. A total of 360 mixed sex Ross 308 1-D-old broiler chickens (180 male and 180 female) were placed in a completely randomized design with 2 × 2 × 2 factorial arrangement of lighting program (continuous or restricted), stocking density (12 or 18 birds/m2), and the provision of a perch (perch or without perch). At d 42, tibial dyschondroplasia (TD), valgus-varus deformity (VVD), footpad dermatitis (FPD), and hock burn (HB) were scored. In addition, tibio-tarsal index, robusticity index, bone weight-length index, tibia crude ash content, and fluctuating asymmetry (FA) and relative fluctuating asymmetry (rFA) of tibia width and length were measured. The incidence of TD increased in broiler chickens subjected to continuous lighting (P

In this study, the effects of requirement level (60 mg/kg) of nano zinc supplementation (46 mg/kg) of breeding quail rations on egg production, weight gain, egg quality characteristics, sperm quality, hatching parameters and liver were determined. 10 week old quails (Coturnix coturnix Japonica) were divided into two groups: control and experiment with 10 replicates were formed under each group that having one male four female in each, a total of 100 (20 male and 80 female) quails were used in the study. At the end of 10 weeks trial period, supplementation of nano zinc does not have any significant effect on weight gain, feed consumption and egg production. In terms of egg quality characteristics, it was seen that the addition of nano zinc had a significantly decrease on egg yolk color (P, Yapılan bu araştırmada, damızlık bıldırcın rasyonlarına gereksinim düzeyini (60 mg/kg) sağlayacak şekilde nano çinko oksit katılmasının (46 mg/kg) yumurta verimi, canlı ağırlık, yumurta kalite özellikleri, sperm kalitesi, kuluçka parametreleri ve karaciğer üzerine olan etkileri incelenmiştir.

The objective of this study was to investigate the effects of photoperiod length and light intensity on leg and eye health, tonic immobility, some blood parameters, carcass, and meat quality characteristics in broilers. A total of 272 one-day-old male broiler chicks (Ross 308) were randomly assigned to four treatment groups based on the photoperiod length (23L:1D or increasing duration of light) and light intensity (20 lux vs. dim light) with four replicates. In this study, photoperiod lenght had no effect on incidence of foot pad and hock burn. On the other hand, the effect of photoperiod lenght had significantinfluenceonthegaitscore.Theincidencesofgaitscore(3+4+5)inbrightanddimlightgroupswasfoundas21.4and41.0%in broilers, respectively. In addition, the effect of light intensity had statistical significanceongaitscore.Thetonicimmobilityduration in 20 lux and dim light groups were 271.53 and 226.78 s, respectively, and tonic immobility duration was unaffected by light intensity. All the blood parameters, except for triglyceride, were not affected by light intensity. The dim light had a negative effect on broiler welfare as demonstrated by increased eye weight and dimensions. Cold carcass yield and whole breast and wing yields were lower in the dim light group than in 20 lux light intensity. The broilers kept with dim light had lower breast meat ultimate pH (6.19) and L* values (54.30) than those reared with 20 lux.
