Nonruminant 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 ...

Performance of Weanling Pigs Fed Increasing Levels

Experiments were conducted to estimate the threonine requirement of pigs weighing 5 to 15 kg and to determine whether excess methionine increased the threonine requirement. Feeding .70% dietary threonine in Exp. 1 maximized (P<.01) gain/feed and minimized (P<:01) plasma urea N. Plasma threonine was increased (P<.01) by threonine supplementat ion and the rate of increase accelerated above .65% d...

Role of rotavirus (reo-like) in weanling diarrhea of pigs.

Piglets weaned abruptly and precociously at 3 weeks of age and placed in a crowded nursery commenced diarrhea 3 to 5 days later. Death losses were low (approximately 6%), but weight gain ceased for 2 weeks. Large numbers of rotavirus (reo-like) particles were seen by electron microscopy in diarrhetic fluids. Sections of intestines showed a loss of adsorptive surface in that villi were shortened...

Bioavailability of iron from amino acid complex in weanling pigs

The objective of the study was to evaluate the iron bioavailability of iron amino acid complex, Availa-Fe compound, as compared to the iron from feed grade ferrous sulfate in weanling piglets. Seventy-two 30-day-old three-way cross piglets, with an average live-weight of 6.41 kg, were randomly allocated into 12 groups of six dietary treatments and two replicates. The control diet (C) included 1...
