Response of Broiler Chickens to Quantitative Feed Restriction with or without Ascorbic Acid Supplementation
Ascorbic acid (vitamin C) supplementation has been documented as a useful tool to improve the performance of laying birds reared under harsh environmental conditions. However, there is limited information on the use of ascorbic acid as a means of ameliorating the stressful conditions imposed by feed restriction. To this effect a 3 × 2 factorial experiment was carried out to evaluate the effect ...
متن کاملEffects of feed restriction and subsequent refeeding on energy utilization in growing pigs.
An experiment was carried out to evaluate the metabolic utilization of energy in crossbred barrows during feed restriction and subsequent refeeding. Ten pigs, initially weighing 52 kg, were used in 5 blocks of 2 littermates each. A 7-d adaptation period (P1) was used in which pigs were offered feed at 2.60 MJ of ME.kg of BW(-0.60).d(-1). This adaptation period was followed by a 7-d period (P2),...
متن کاملFeed Energy Evaluation for Growing Pigs*
Pigs require energy for maintenance and productive purposes, and an accurate amount of available energy in feeds should be provided according to their energy requirement. Available energy in feeds for pigs has been characterized as DE, ME, or NE by considering sequential energy losses during digestion and metabolism from GE in feeds. Among these energy values, the NE system has been recognized ...
متن کاملFeed physical form and formic acid addition to the feed affect the gastrointestinal ecology and growth performance of growing pigs.
The effect of feeding a coarsely ground meal (COARSE) and a finely ground pelleted diet with 1.8% (as-fed basis) added formic acid (ACID) was compared with feeding a standard finely ground pelleted diet (STD) on the gastrointestinal ecology of growing pigs at different intervals after feeding. One hundred five castrated male growing-finishing pigs (initial BW 27 kg) were used. At a BW of 63 kg,...
متن کاملEffect of feed restriction on the performance and behaviour of pigs immunologically castrated with Improvac®.
For centuries, entire male pigs have been castrated to reduce the risk of boar taint. However, physical castration of pig is increasingly being questioned with regard to animal welfare considerations. Immunization against gonadotrophin releasing hormone (GnRH) provides an alternative to physical castration. Using the currently available commercial product (Improvac®; Pfizer Animal Health), a tw...
