Sulfur amino acids requirements of laying hens in low protein diets

An experiment was coducted with White Leghorn hens in early laying stage to determine the influence of dietary crude protein (CP) concentration on the requirement for total sulfur amino acids (TSAA).The experiment was conducted for 8 weeks on 600 commerical layer hens, Hy-Line w-36 (six groups of 4 hens, 30 weeks old). This experiment arranged to factorial 5 5 in a complete random design with f...

Effect of Tryptophan Supplementation in Protein Deficient Diets on Performance, Gut Development and Immune Responses in Broiler Chickens

The current trial was conducted to investigate effects of tryptophan (Trp) supplementation in crude protein (CP) deficient diets on performance, gut development and immune responses in broiler chickens. A total of 420 day-old broiler chicks (Ross 308) were assigned to one of 6 dietary treatments, ‎comprising 5 replicates in a completely randomized design including: 1) ‎control diet (CTL) (diet ...

Dried distillers grains with solubles in laying hen diets.

A study was conducted to test the inclusion rate of corn dried distillers grains with solubles (DDGS) in laying hen diets on egg production (EP) responses for a full production cycle. A total of 288 Bovan Single Comb White Leghorn laying hens were fed diets containing 0, 5, 10, 15, 20, or 25% DDGS from 24 to 46 wk (phase 1) and 47 to 76 wk (phase 2) of age. The diets were formulated to be isoca...

Olive Cake and Barley Malt Rootlets in Hen Diets to Improve Egg Lipids and Fatty Acids

The aim of the present study was to investigate the possibility of improving egg lipids and fatty acids composition of laying hens through inclusion of olive cake plus barley malt rootlets in the diets. Seventy, 54-week-old, Lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 28.5 g olive cake (OC) + 25.5 g barley malt rootl...
