Diet selection priorities in growing pigs offered a choice of feeds
Two experiments were conducted to test whether young pigs are capable of discriminating against a feed based on its nutrient balance (or protein value) and/or the presence or absence of anti-nutritional factors, and whether there is an order of preference. In each experiment 48 Large White x Landrace female pigs weighing 16.5±1.50 kg were randomly allocated to one of either 12 dietary treatment...
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 کاملDigestible phosphorus needs of terminal-cross growing-finishing pigs.
Growth and digestion experiments were conducted to estimate the digestible P needs of terminal-cross growing-finishing pigs fed sorghum-soybean meal-based diets from 25 to 118 kg. Dietary available P levels approximated the levels recommended by the NRC (1988) or were approximately 25% above or below those levels. Up to 80 kg, dietary treatment did not affect performance; from 80 to 118 kg, the...
متن کاملNet energy of soybean oil and choice white grease in diets fed to growing and finishing pigs.
The objectives of this experiment were 1) to determine the NE of soybean oil (SBO) and choice white grease (CWG) fed to growing and finishing pigs, 2) to evaluate the effects of inclusion rate of SBO on the NE by growing and finishing pigs, and 3) to determine if there is a difference in the NE of SBO and CWG between growing and finishing pigs. Forty-eight growing (initial BW: 22.13 ± 1.78 kg) ...
متن کاملGrass silage in diets for organic growing-finishing pigs
In this study, organically raised pigs received an increasing proportion of grass silage up to 10 and 20% dry matter in the daily ration in the grower and finisher period, respectively, to determine the effects of grass silage on feed intake and growth performance. The pigs receiving a mixture of grass silage and compound feed ingested 0.3 kg DM/d (13% of their daily ration) as grass silage and...
