120 selected layers (Bovans Goldline hybrid) aged 19 weeks with an average weight of 1 735 g were divided into two balanced groups: control group (Group C) and experimental (Group E). Layers were rear...
We examined the effect of orally administered L-carnitine (at a dose of 30 mg per kg of feeding mixture) on egg hatching and some haematological and biochemical parameters of blood plasma in COBB 500 ...
Forty-five Hisex commercial layers and forty-five local Saudi breed layers were used to determine the acceptable limit of short-term water restriction in the late phase of production, when the problem...
A feeding trial of 20 weeks duration was conducted using 240 point-of-lay Hy-line layers to study the nutritive value of diets containing low-energy agro-industrial by-products namely wheat bran, maiz...
Sixty Harco layers in their 12th weeks of lay were randomly allocated to six treatments, ie T1 (100% layers mash), T2 (layers mash+1% fishmeal), T3 (layers mash+2% fishmeal), T4 (layers mash+3% fishme...
The trial reported herein investigated the use of maggot meal as a replacement for fish meal in a cassava products-based layers diet. Old laying hens (50 weeks in lay) made up of two hybrids (Isa Brow...
Selected 120 layers, hybrid breed Bovans Goldline, were divided into two balanced groups: control (C) and experimental (E) group. The layers were raised in three-floor cage technology with automatic...
We have previously mapped quantitative trait loci (QTL) affecting egg production and quality traits using a reciprocal cross of two divergent egg-layer lines. The lines differ also in body weight, and...
Two experiments were conducted separately to study the effect of astaxanthin on production performance and egg quality in laying hens and meat quality in finishing pigs. In Experiment 1, four hundred ...
In this study, canonical correlation analysis was applied to layer data to estimate the relationships of egg production with age at sexual maturity, body weight and egg weight. For this purpose, it wa...
An experiment was conducted (28 to 44 weeks) to study the laying performance, shell quality, and nutrient retention of White Leghorn layers fed different levels of non-phytate phosphorus (NPP). Six le...
The present study was conducted to evaluate effect of Sauropus androgynus extract (SAE) on egg production and lipid metabolism in layer chickens. Forty-eight layers aged 42 weeks (strain RIR) were dis...
