In each experiment, diets were formulated to provide the growing kitten with the essential amino acids at or above the level of requirement. Expt 1 utilized a 4 x 4 balanced Latin square design with two groups of kittens (four male and four female). The crystalline L-amino acid diets were presented ...
متن کاملNonruminant Nutrition: Weanling Pigs - Additives
To evaluate the developmental regulation of nutrient transporter gene expression in the small intestine, piglets from each of seven sows were killed at birth (d 0), during lactation (d 1, 3, 7, 14, and 21) and post-weaning (d 22, 24, 28, and 35; weaned at d 21). Intestinal segments (duodenum, jejunum, and ileum) were collected for RNA isolation. The abundance of mRNA was determined by Northern ...
متن کاملThe Effect of Ergot on the Performance of Weanling Pigs
Ergot contains numerous poisonous substances (alkaloids), which upon ingestion by animals may lead to poor growth rate, decreased feed consumption and poor feed efficiency. The effect will depend on the age or physiological stage of the animal, and the amount consumed. Results obtained in this study indicate that the consumption of diets containing more than 0.10% high alkaloid ergot by weanlin...
متن کاملNonruminant Nutrition: Weanling Pig - Vitamin & Mineral
Poultry fat has become a more economical source of energy than byproducts currently used. Therefore, this study was conducted to determine the effects of dietary fat source (poultry fat or beef tallow) in finishing diets for cattle on the fatty acid composition of beef. Sixty Angus crossbred steers (410.8 kg initial BW) were stratified by source, blocked by weight, and assigned within block to ...
متن کاملAluminum toxicity and behavior in the weanling Long-Evans rat
Muricidal behavior, weight, open-field activity, passive-avoidance learning, and learning of an eight-arm radial maze were assessed in Long-Evans hooded rats subjected as weanlings to 60 days of oral administration of aluminum hydroxide gel (Group AA) or tap water (Group NA). Measurement of brain aluminum content indicated that the groups did not differ significantly in neural incorporation of ...
