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...
متن کاملLaying 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...
متن کاملPerformance and nutrient utilization of laying hens fed low-phosphorus corn-soybean and wheat-soybean diets supplemented with microbial phytase.
Two experiments were conducted with laying hens (Lohmann Brown) in an individual cage system and with single feeding conditions. Experiment 1 (n = 24) was a performance trial (22 to 61 wk) to evaluate phytase effects on performance and nutrient utilization in corn-soybean meal (CSM1) and wheat-soybean meal (WSM1) basal diets (0.12% NPP; 3.1% Ca) supplemented (300 U/kg) with an experimental micr...
متن کاملProductive Performance of Laying Hens Fed Different Levels of Distillers Dried Grains with Solubles with or without Certain Feed Additives
The objective of this work was to evaluate the inclusion of distillers dried grains with solubles (DDGS) as substitution for soybean meal in Hisex Brown laying hen diets with or without enzyme or vitamin E supplementation on productive performance. A total number of 180 Hisex Brown laying hens at 26 weeks of age were randomly divided into 15 treatment groups in a 5 × 3 factorial design experime...
متن کاملEffect 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 ...
