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...

treatments and were intermediate for the LCPPH. From 12 to 13 wk FI was significantly higher for CON and LCPPH, compared to LCP pens. Feed conversion and mortality were not affected by treatment. Processing and cut-up of toms at 13 wks resulted in no treatment differences in the weight of the breast, legs, neck, skin, wings, thighs, back, abdominal fat pad or yield as a percent of the last BW, ...
متن کاملEffects of broiler breeder management on pullet body weight and carcass uniformity.
An experiment was conducted to study the effect of broiler breeder feeding management practices on pullet performance, BW uniformity, and carcass traits during rearing (to 22 wk of age). At 3 wk of age, 1,200 Ross 308 breeder pullets were assigned to one of 5 treatments: 1) control: standard mash diet, fed daily; 2) high fiber: mash diet containing 25% lower nutrient density, fed daily; 3) scat...
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 کاملFeeding broiler breeder males. 4. Deficient feed allocation reduces fertility and broiler progeny body weight.
Two experiments were conducted to evaluate the effects of male broiler breeder feed intake on broiler progeny performance. In experiment 1, a low cumulative nutrition program supplied 29,580 kcal of ME and 1,470 g of CP, whereas a high cumulative nutrition program supplied 33,500 kcal of ME and 1,730 g of CP to photostimulation at 21 wk of age. Two diets (HiDiet and LoDiet) were formulated, and...
