Moraes, Thania Gislaine Vasconcelos de
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...

Fall 2010
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 Females
DownloadFall 2013
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...

Metabolic status and reproduction in precision-fed broiler breeders: Impact of growth trajectories
DownloadFall 2021
Broiler breeders are subjected to feed restriction programs to control excessive growth. However, current levels of feed restriction are becoming severe, raising welfare and suboptimal reproductive performance concerns in underfed breeders. To circumvent the issue, we studied new strategic growth...

The effects of broiler breeder diet supplementation of canthaxanthin and 25-hydroxyvitamin D3 and age on offspring performance traits and innate immune function
DownloadSpring 2018
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...
