The effects of broiler breeder dietary energy and protein during rearing and dietary energy level of lay diets on egg composition, offspring performance and carcass yield were evaluated. Pullets were fed a diet containing high ME (2,736 kcal/kg; HEREAR), or low ME (2,528 kcal/kg; LEREAR) combined...
This project researched the effects of pullet-phase feed restriction methodology or management and hen-phase diet fortification on female broiler breeder BW and carcass trait uniformity as well as on performance of the broiler offspring. Feed treatments had a significant effect on female BW and...
Impacts of Environmental Temperature and Dietary Energy on Core Body Temperature and Efficiency in Broiler Breeder FemalesDownload
The effects of environmental temperature, dietary energy, housing system, time of feeding and day length on core body temperature (CBT) dynamics in broiler breeder females was studied in a series of experiments. Environmental temperatures within the range of 15 to 27˚C resulted in a CBT of 39.8...
The effects of broiler breeder diet supplementation of canthaxanthin and 25-hydroxyvitamin D3 and age on offspring performance traits and innate immune functionDownload
Experiments were conducted to understand the effect of dietary canthaxanthin (CXN) and 25-hydroxyvitamin D3 (25-OHD3) on broiler breeder productivity, progeny performance traits and progeny innate immune function. Beginning at 22 wk of age, breeder hens were fed either 1) Control (Vitamin D3 at...
