Turkish Journal of Veterinary & Animal Sciences
A study was conducted to evaluate the impact of varying dietary inoculated compost levels on production performance, egg quality traits, and immune response of white laying hens (LSL) during the peak production phase (28 to 40 weeks). For this purpose, a total of 270 birds were randomly distributed into 5 dietary groups with 6 replicates each in techno battery cages having 9 birds per replicate following completely randomized design. Experimental diets were comprised of an increasing level of inoculated compost (0, 3, 6, 9, and 12%) and each diet was balanced (iso-caloric and iso-nitrogenous). The control group birds fed a …

The present study aims to evaluate the effect of lower or higher eggshell temperatures from days 7 to 21 on hatching performance, bone and blood parameters, and egg production along with the age of laying chickens. A total of 3150 eggs obtained from a white egg-type breeder were divided randomly into 3 groups of 1050 eggs. From 7 to 21 days, eggs were incubated at one of three eggshell temperatures: Control (IC) 37.5 °C, low (IL) 36.9 °C, and high (IH) 38.5 °C. At hatch, chicks were weighed, and blood was collected to measure total Ca, inorganic P, and ALP …

In this study, the effects of beta-mannanase supplementation to laying hens? diets with different guar meal (GM) ratios on performance and egg quality traits were investigated. The experimental period lasted 126 days. Ninety-six Lohman Brown hens at the age of 56 weeks were kept in individual cages. They were divided into 8 treatment groups as follows: 0% guar meal (GM0) (control); 0% GM + 0.05% beta-mannanase (GM0E); 8% GM (GM8); 8% GM + 0.05% beta-mannanase (GM8E); 16% GM (GM16); 16% GM + 0.05% beta-mannanase (GM16E); 24% GM (GM24); and 24% GM + 0.05% beta-mannanase (GM24E).

Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to investigate the effects of dietary chicken grill oil (CGO) and sunflower seed oil (SO) on performance, some serum and egg yolk biochemical parameters, and blood and liver oxidant/antioxidant status of laying hens. Fifty-four 19-week-old Lohmann laying hens were randomly assigned to three groups. The groups were fed experimental diets containing 5% SO, 5% CGO1, or 7.5% CGO2, respectively. Diets and water were provided ad libitum over 17 weeks. The feed efficiency ratios and cholesterol content in egg yolks with cholesterol and the triglyceride levels in serum were not affected by the diets. However, …

Turkish Journal of Veterinary & Animal Sciences
This study examines the effect of grandparent, parent, and hybrid brown chickens, selected from 3 generations of pure lines, on hybrid egg-laying performance. The study was conducted at the Poultry Research Station of Ankara. In the first stage, 4 grandparent lines were derived from 2 pure line base populations. Grandparent lines included 2 male lines (low body weight and high egg weight) and 2 female lines (low body weight and high egg production). In the second stage, grandparent male and female lines were reciprocally crossed to produce 4 parent lines. In the third stage, male and female parental lines were …

Light Microscopic Investigations On The Oviduct In Hens, Asuman Özen
Turkish Journal of Veterinary & Animal Sciences
In this study, the oviducts of 10 laying hens aged 8 months and 10 oviducts of pullets aged 2 months were comparatively examined. The oviducts of hens consisted of five regions: infundibulum, magnum, isthmus, uterus and vagina. Tissue samples were taken from the five oviduct regions. The samples were fixed in 10% neutral formalin and embedded in paraffin and then cut into 6 micron sections. Tissue sections were stained with triple, PAS, PAS/Ab, Ab, performic acid/Ab and examined with a light microscope. The epithelium of the oviduct consisted of ciliated and secretory cells. In laying hens, activated tubular glands were …

Possibilities Of Utilizing First Carbonation Sludge From The Sugar Industry As A Calcium Source In Layer Diets, Güray Erener, B. Zehra Sariçi̇çek
Turkish Journal of Veterinary & Animal Sciences
This study was carried out to investigate the possible use of first carbonation sludge from the sugar industry in layer diets. 324 Babcock B-300 hens were used. Ground marble was replaced in the experimental diets by the sludge to provide the calcium requirements at the rates of 0, 20, 40, 60, 80 and 100%, respectively. Statistical analysis showed that there were significant differences between percentages (P0.05). The result of this study suggest that first carbonation sludge from the sugar industry could replace ground marble and the level of replacement should be 20% if the sludge is used in the layer …
