Performance of Commercial Laying Hens When Fed Diets with Various Sources of Energy

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

Performance and Egg Quality of Laying Hens Fed Diets Supplemented with Herbal Extracts and Flaxseed

In this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of Leghorn-type laying hens (Hy-Line W-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. The treatment groups were: 1) Control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

Laying performance and eggshell quality in laying hens fed diets supplemented with prebiotics and organic acids

The aim of the study was to evaluate the effect of organic acids and the prebiotic fructans on egg production and eggshell quality when added to the layer diet with different levels of calcium and phosphorus. The experiment was carried out on 168 Bovans Brown hens, allocated to 14 groups of 12 replications. Each hen (replication) was kept in an individual cage 40 cm × 40 cm in size. A 2 × 7 fac...

Effect of Methionine and Energy Level in High Protein Organic Diets Fed to Laying Hens*

The objective of a 2 × 2 factorial study with laying hens was to evaluate the effect of dietary energy and DL-methionine (Met) supplementation in a high protein but sulphur amino acid deficient organic diet for laying hens on egg production, egg quality, and N retention and N excretion in manure. The model trial was conducted with 72 Bovans Brown hens from 24 to 53 weeks of age, allocated to 4 ...
