History, changing scenarios and future strategies to induce moulting in laying hens

Evaluation of Production Performance and Some Qualitative Characteristics of Eggs in the Late Stages of Laying Hens Using Some Pro- and Anti-Inflammatory Strategies

     Since inflammation is considered as one of the major challenges in different parts of the livestock industry, therefore this study was done to evaluate the combinatorial inflammatory strategy and simultaneous usage of beta-2 agonist and glucocorticoid drugs on some performance characteristics in laying hens at late production stage and some of qualitative characteristics. The research was ...

Effect of Different Levels of Mineral and Vitamin Premix on Laying Hens Performance during the First Laying Phase

An experiment was conducted to evaluate the effects of different levels of mineral and vitamin premix on performance and egg traits of laying hens from 37 to 49 weeks of age. Two hundred and forty laying hens (Hy-Line W-36 strain) were randomly assigned to 5 dietary treatments of four replicates each with 12 hens per replicate). The levels of mineral and vitamin premixes in the experiment were ...

Effects of Dietary Supplemental Vitamin E and Chromium on Egg Production, Egg Quality and Blood Parameters of Laying Hens under Thermoneutral or Heat Stressed Conditions

The effects of dietary supplemental vitamin E (VE) and chromium (Cr) on egg production (EP), egg quality, serum concentrations of Cr and insulin and activity of glutathione peroxidase (GSH-Px) were evaluated in Lohmann LSL-Lite laying hens reared under thermoneutral or heat stress (HS) conditions. A total of 144 laying hens were distributed in 24 cages and assigned to feed four diets including ...

Response of laying hens to supplementation with various fatty acids when fed diets inadequate in protein and sulphur amino acids

The effect of different levels of Fenugreek (Trigonella foenum-graecum L.) powder and extract on performance, egg quality, blood parameters and immune responses of laying hens in second production cycle

The present study was carried out to determine the effects of fenugreek powder (FP) and extract (FE) on performance, egg quality, blood parameters and immune responses of laying hens. One-hundred and fifty Leghorn laying hens were used in a completely randomized design with five treatments and five replicates for eight weeks. Treatments were various levels of FP and FE including zero (control; ...
