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...
Replacement of Fish Meal with Maggot Meal in Cassava-based Layers' Diets
cassava egg quality fish meal maggot-meal layers
2009/7/30
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...
Long-term application of clinoptilolite via the feed of layers and its impact on the chemical composition of long bones of pelvic limb (femur and tibiotarsus) and eggshell
Zeofeed crude protein ash
2015/3/17
Selected 120 layers, hybrid breed Bovans Goldline, were divided into two balanced groups: control

Chromosome regions affecting body weight in egg layers
Egg laying chickens QTL mapping body weight
2010/8/9
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...
