Selection for Efficiency of Production in Australorp Hens
نویسنده
چکیده
4. The cross between both control lines is higher in egg production than, and similar in total egg mass and feed efficiency to, the industry L x A crosses, indicating that little or no genetic improvement has been made in these characters in some commercial breeding flocks in the past 10 years. This aspect of the above experiment in particular needs to be confirmed. If true, it will indicate an urgent need for industry to review and change selection criteria.

The development of genomic selection has created new strategies in animal breeding programs. The aim of this study was to investigate the efficiency of genomic selection in breeding programs of native hens. In this study, a reference scenario with 3380 birds using pedigree and phenotypic information was simulated and the expected genetic progress was derived deterministically with the software ...

The experiment was carried out in poultry experimental station belonging to NRC, Cairo, Egypt. A total of 120 Fayoumi layers, 45 weeks old, were randomly divided into four equal groups. Each group included three replicates (10 hens in each). The first group was fed the control diet containing 3.3% gram Ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram Ca, respectivel...
متن کاملCharacterization of energetic efficiency in adult broiler breeder hens.
This trial characterized residual feed intake (RFI) and residual maintenance requirement (RME(m)) as measures of energetic efficiency in broiler breeder hens. The RFI was defined as the difference between observed and expected ME intake and RME(m) as the difference between observed and expected maintenance requirements. A total of 600 Ross 708 1-d-old pullets were placed in floor pens. At 16 wk...

The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...
