Effect of body weight on the biological value of proteins for growing swine.
N ITROGEN balance, body weight gain, slaughter experiments, and plasma regeneration methods have been employed to evaluate proteins and amino acids fed to various animals. Limitations imposed by facilities and economy often render certain of these impractical for swine investigations, especially when costly dietary ingredients are involved. In this case the nitrogen" balance method with its rel...
متن کاملDietary calcium and phosphorus levels for growing swine from 18 to 57 kilograms body weight.
A randomized complete block design experiment was conducted using 408 crossbred pigs to evaluate the effects of six dietary Ca/P levels for growing swine (18 to 57 kg). Total dietary P levels ranged from .40 to .90% in .1% intervals with Ca concurrently increased at a 1.3:1 ratio in a 16% protein corn-soybean meal diet. Dicalcium phosphate and limestone were the source of inorganic Ca and P. Fo...
متن کاملEffect of starter feeding program on growth performance and gains of body components from weaning to market weight in swine.
Three experiments were conducted to test the hypothesis that different starter feeding programs (High, high quality; Low, low quality) will affect growth performance and body composition of pigs from weaning to market weight and that this effect may be influenced by gender (barrows or gilts) and breed (F, Yorkshire-Duroc x Hampshire; P, PIC Camborough 15 x PIC line 405). In Exp. 1, 21 +/- 4-d-w...
متن کاملEffects of neutering on food intake, body weight and body composition in growing female kittens.
To understand the effects of neutering on food intake, body weight (BW) and body composition in kittens, data from an unrelated study were subjected to post hoc analysis. A total of twelve pairs of 11-week-old female littermates were randomly assigned to either a neutered group (neutered at 19 weeks old) or an entire group (kept entire) and offered free access to a dry diet until the age of 1 y...
متن کاملQuantitative genetics of transgenic mice: components of phenotypic variation in body weights and weight gains.
Transgenic mice possessing an ovine growth hormone gene were used to study the effects of elevated growth hormone on quantitative genetic variation. Males hemizygous for the transgene were mated to wild-type females to produce half- and full-sib families in which approximately half the progeny were transgenic and half were wild type. Analyses of body weights at 3-10 weeks, and weight gains from...
