Feeding behavior of growing-finishing pigs reared under precision feeding strategies.
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 evaluated, namely a conventional 3-phase program in which pigs were fed with a constant blend of diet A (high nutrient density) and diet B (low nutrient density) and 4 daily phase-f...
متن کاملChoice Feeding Experiments with Growing Pigs
The amino acid requirements of growing animals are predicted to change with time, due to changes in the requirements for maintenance and for growth. Because food intake also changes with time, the question of optimising the dietary concentrations of a m i n o a c i d s d u r i n g t he g rowing period of animals is difficult to rcsolvc w i t h o u t resorting to computer mod&. Even such models ...
متن کاملHeat Stress Reduces Intestinal Barrier Integrity and Favors Intestinal Glucose Transport in Growing Pigs
Excessive heat exposure reduces intestinal integrity and post-absorptive energetics that can inhibit wellbeing and be fatal. Therefore, our objectives were to examine how acute heat stress (HS) alters intestinal integrity and metabolism in growing pigs. Animals were exposed to either thermal neutral (TN, 21°C; 35-50% humidity; n=8) or HS conditions (35°C; 24-43% humidity; n=8) for 24 h. Compare...
متن کاملHeat stress reduces barrier function and alters intestinal metabolism in growing pigs.
High ambient temperature exposure can cause major reductions in intestinal function, pig performance, and, if severe enough, mortality. Therefore, our objective was to examine how acute heat stress (HS) alters growing pig intestinal integrity and metabolism. Individually penned crossbred gilts and barrows (46 ± 6 kg BW) were exposed to either thermal neutral (TN; 21°C; 35 to 50% humidity; n = 8...
متن کاملHeat stress affects the apparent and standardized ileal digestibilities of amino acids in growing pigs.
Heat stress (HS) appears to impair the pig's small intestine digestive and absorptive capacities and, therefore, may affect the AA digestibilities. A crossover-designed experiment was conducted utilizing two 7-d periods with 8 pigs (30.8 kg initial BW) surgically fitted with T-type cannulas at the terminal ileum to analyze the effect of HS on both apparent (AID) and standardized (SID) ileal dig...
