Feeding behavior of growing-finishing pigs reared under precision feeding strategies
(Amer Soc Animal Science, 2016-07-01)
The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 +/- 2.2 kg) over 84 d. Five different feeding programs were ...
The use of nonlinear programming as a tool for maximum profit feed formulation of broilers
The purpose of this study was to compare linear and nonlinear programming models for feed formulation, for maximum profit, considering the real variation in the prices of the corn, soybean meal and broilers during the ...
Effects of broiler breeder genetic, diet type, and feeding program on maternal antibody transfer and development of lymphoid tissues in chicken progeny
(Poultry Science Assoc Inc, 2011-12-01)
Maternal antibody (MatAb) transfer is important for early chicken survivability. Diet composition and the amount of feed given to breeder pullets during rearing may affect the development of immunity and the transfer of ...
School feeding in Brazil: a Cost Assessment of the National Program
The Brazilian National School Feeding Program (PNAE) plays an important role in Brazilian National Education and given its broad structure and context, may serve as a guide for other developing countries. However, due to ...
Broiler breeder feeding programs and trace minerals on maternal antibody transfer and broiler humoral immune response
Breeder feed restriction may negatively affect broiler progeny immunity. Sources of trace minerals (TM) with higher bioavailability in breeder diets have been reported to enhance humoral and cellular immunity in broiler ...
Environmental impacts of precision feeding programs applied in pig production
(Cambridge Univ Press, 2018-09-01)
This study was undertaken to evaluate the effect that switching from conventional to precision feeding systems during the growing-finishing phase would have on the potential environmental impact of Brazilian pig production. ...
