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 ...
متن کاملPerformance 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...
متن کاملToxicity of Crude Neem Leaf Extract Against Housefly Musca domestica L. Adults as Compared With DDVP, Dichlorvos
219 Abstract: Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly (Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was treated in 0.1, 0.2, 0.4, 0.8 and 1.6 microgram/fly doses. Lethal dose values were calculated with probit analysis and LD50 and LD90 values were found to be 8.4 and 169.8 ug/fly of ne...
متن کاملRole 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...
متن کاملBioavailability 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...
