The objective of this experiment was to replace soya bean oil with glycerol in laying hen diets and assess the change's effect on performance, parameters of egg quality and the egg fatty acid profile. A total of 60 44-week-old Hy-Line W36 laying hens were distributed according to a completely randomised experimental design into four treatments consisting of glycerol substitutions for soya bean ...

This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive wherea...

Twenty 35-wk-old chickens, including 10 Single Comb White Leghorn (SCWL) and 10 Rhode Island Red (RIR) hens, were used to examine the effects of egg and yolk weights on egg yolk antibody (IgY) production in the two strains of chickens immunized with BSA. The SCWL chickens had a greater (P < 0.01) percentage hen-day production and greater egg and yolk weights than did the RIR chickens. However, ...

The current study investigated the effect of short-term selection for four week body weight (BW) on performance of divergent lines of Japanese quail and their crosses. The mean of BW at hatching time, one, two, three and four week oldand BW at sexual maturity time, age at sexual maturity, number of eggs (from 50 to 100 days old), mean of egg weight, percentage of fertility and hatchability in e...

background: improvement of hatchability in aging broilerbreeder has economic justification. objectives: the main objective ofthis study was to determine the effect of dietary anethum graveolensessential oil on egg quality, some plasma metabolites and hatchability inbroiler breeder hens. methods: a total number of eighty hens and eightcocks from ross 308 strain of 105 weeks old were divided into...

The 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicates and 10 eggs per each replicate. Treatments including: (T1; control; without injection), (T2; injected with 0.3 ml saline 9.0%; sham control), (T3, T4 and T5) 25, 75, 125 ppm Fe-Nano, (T6, T7 and T8) 50, 100, 150 ppm Fe-Nano-Alimet chelate, (T9, T10 and T11) 50, 100, 150 ppm Fe-Aliment ch...

AIM This study was undertaken to compare the immunoglobulin Y (IgY) level and its efficacy in laying hens of four different breeds of poultry (viz., Vanraja, Gramapriya, BlackRock, and KalingaBrown) and its relative transfer in egg yolk and chick. MATERIALS AND METHODS This study was conducted in 48 apparently healthy laying hens vaccinated with Salmonella inactivated polyvalent vaccine, eggs...

this trial was conducted to evaluate the effects of different dietary factors that affect egg cholesterol concentration in laying hens of 56 to 70 weeks of age. three hundred and ninety six hy-line w36 laying hens were subjected to 11 experimental treatments, each treatment consisting of 4 replicates, each replicate of 9 hens. dietary treatments included the control, made up of corn plus soy me...

Effects of polyunsaturated fatty acid (PUFA) and vitamin E (VE) supplementation in the diet of breeder hens on the egg quality and hatchability, lipid peroxides of the egg yolk, and development of the newly-hatched offspring chicks were investigated. A total of 800 Avian 48, 28 wk-old broiler breeders were assigned randomly to 4 groups with 4 replicates of 45 females and 5 males. Each group was...

The aim of the research was to investigate the effects of divergent selection on some production and clutch traits in Japanese quail (Coturnix coturnix japonica). Over 5 generations divergently selected two Japanese quail lines (HBW: High Body Weight and LBW: Low Body Weight) and control line (C) that derivate from a base random bred population were used in this study. Weight of first egg, age ...
