Growth heterogeneity in broiler breeder pullets
Uniform growth is a desirable trait in all large-scale animal production systems because it simplifies animal management and increases profitability. In parental broiler flocks, so-called broiler breeders, low growth uniformity is largely attributed to the feed competition that arises from quantitatively restricted feeding. As feed restriction is crucial to maintaining healthy and fertile breed...
متن کاملModeling metabolizable energy utilization in broiler breeder pullets.
The objective of this study was to determine models for ME requirements for broiler breeder pullets using the factorial method. The influence of the temperature on maintenance ME requirements was determined by experiments conducted in three environmental rooms with temperature kept constant at 15,22, and 30 degrees C, using the comparative slaughter technique. The energy requirements for weight...
متن کاملIn vitro propagation of some promising genotypes of jojoba (Simmondsia chinensis)
Nodal segments (1.5 3.0 cm long) of six promising jojoba genotypes were cultured in vitro on solidified MS medium supplemented with BA in combination with different concentrations of NAA, IAA or IBA for shoot formation. The plant growth regulators combination of 5.55 μM BA + 7.1 μM IAA proved the best for shoot initiation and subsequent growth. Some explants of the jojoba genotypes, PKJ-3 and P...

متن کاملEffects of dietary protein on restrict-fed broiler breeder pullets during a coccidial challenge.
In each of two experiments with young, feed-restricted broiler breeder pullets, the effects of differences in dietary protein intake on intestinal development and growth were studied. All pullets were restrict-fed either a 15 or 19% CP diet to see whether differences in dietary protein would influence intestinal growth in the face of controlled exposure to coccidiosis. In each experiment, pulle...
