Threonine requirement of pigs weighing 5 to 15 kg.
Weanling crossbred pigs (avg initial wt 6.4 kg) were fed diets containing six levels of threonine to determine the threonine requirement of young pigs fed diets somewhat similar to those used in commercial swine production. The diets (16% crude protein) were composed primarily of grain sorghum, oat groats and soybean meal supplemented with minerals, vitamins, lysine, tryptophan, methionine and ...
متن کاملIsoleucine requirement for late-finishing (87 to 100 kg) pigs.
Three pig trials were carried out to determine the true digestible Ile requirement for maximal weight gain and minimal plasma urea nitrogen (PUN) of late-finishing (87 to 105 kg) pigs. In Exp. 1, an Ile-deficient basal diet was developed and confirmed to be markedly deficient in Ile, yet fully efficacious when fortified with surfeit Ile. This diet contained corn and dried red blood cells (RBC) ...
متن کاملProtein requirement of baby pigs on low-fat diets.
For some time studies have been made in this laboratory on the use of the baby pig as an experimental animal, and during this work diets low in fat have been found to support satisfactory performance (Tribe, 1954; McCrea & Tribe, 1956). This finding is somewhat surprising in view of the fact that sow’s milk is very rich in fat. For routine rearing of piglets a low-fat diet is preferable to one ...
متن کاملConcentration of metabolizable energy and digestibility of energy, phosphorus, and amino acids in lemna protein concentrate fed to growing pigs.
Lemna protein concentrate (LPC; 68.0% CP) is produced by extracting protein from de-oiled and dehydrated biomaterials from plants of the Lemnaceae family and may be used as a protein source for animals. There are, however, no published data on the nutritional value of LPC fed to pigs. Three experiments were, therefore, conducted to determine the concentration of ME, the standardized total tract...
متن کاملResponse to dietary digestible energy concentration in growing pigs fed cereal grain-based diets.
Understanding how energy is utilized by the pig, and how the pig responds to changes in dietary energy concentration, is essential information in determining the optimal concentration of dietary energy under farm conditions, which are often highly diverse. The objective of these experiments was to determine how changes in dietary DE concentration, achieved through graded changes in diet composi...
