Dietary lysine requirements of segregated early-weaned pigs

Energetics of Segregated Early Weaned Pigs

The energetics of early weaned (13 to 16 days old) pigs were examined under four temperature regimes. The pigs, in groups of 10 (0.28 m2/pig), were housed in the indirect calorimeter chambers at initial air temperatures of 31.1, 28.9, 26.7, or 24.4°C which then were decreased by 1.1°C per week for the three weeks of the post-weaning period. The feed efficiency and average daily gain during the ...

Determination of the Lysine Requirement in Segregated Early We

Two growth trials involving 140 weanling pigs were conducted to determine the dietary lysine requirement to maximize growth performance in segregated early-weaned pigs. Pigs were housed in an environmentally controlled off-site nursery. In Experiment 1, 60 pigs (14±2 days of age and 9.3 lb BW) penned in groups of three (5 pens per treatment ) were used to evaluate four dietary lysine levels (1....

Characterization of gastrointestinal microbial and immune populations post-weaning in conventionally-reared and segregated early weaned pigs

Dietary Bovine Colostrum Increases Villus Height and Decreases Small Intestine Weight in Early-weaned Pigs

This experiment examined the effect of dietary spray-dried bovine colostrum on intestinal histology and organ weights in early-weaned pigs. In a randomised complete block design, twelve 14-day-old weaner pigs were offered a diet containing either 5% spray-dried bovine colostrum or no colostrum (control). Diets were formulated to contain 14.8 MJ/kg DE, 1.26% available lysine and to meet or excee...

Dietary Glutamine Supplementation Enhances Weaned Pigs Mitogen-Induced Lymphocyte Proliferation*

Two experiments involving 92 crossbred, 21 day old weaned pigs were used to evaluate the effect of glutamine supplement in a dietary or culture medium on lymphocyte proliferation. In Exp. 1, 88 pigs were fed diets supplemented with 0, 0.5, 1.0, or 1.5% glutamine for 28 days. Lymphocytes were prepared from peripheral blood mononuclear cells (PBMC), ileal Peyer’s patches (PP), the mesenteric lymp...
