Supplementing weanling pigs with high concentrations of Zn and the Zn availability of Zn sources for weanling pigs
… conducted to investigate the supplementation of weanling pigs with high levels of Zn and to compare the availability of Zn from several Zn sources for weanling pigs. In the first four trials, supplementing Zn by injecting Zn acetate either i.m. or i.p. at various times near weaning did not …

Novel soybean products fed to weanling pigs
Several studies were conducted to measure the potential impact of feeding novel soybean products to young swine. The first experiment was conducted to determine the impact of heat treatment on AA digestibility with an emphasis on the effect that trypsin inhibitors have on protein digestion. The …

Systemic growth promoting actions of copper in weanling pigs
… Co of 150 ppm was found to be detrimental to weanling pigs. Therefore, inorganic Co feeding is of limited use in studying Cu-stimulated growth. The effect of intravenously injected Cu on growth was studied in two experiments with a total of 89 pigs. Amounts of Cu injected were calculated to …

Nutritional evaluation of fermented soybean meal fed to weanling pigs
… replace animal protein sources in diets fed to weanling pigs during the initial 28 d post-weaning. Results from the 3 experiments indicated that inclusion of 10% FSBM may replace fish meal, chicken meal (CM), or poultry by-product meal (PBM) without impacting ADG, ADFI, or final BW of the pigs. …

Ecology of Lactobacillus in the gastrointestinal tract of the weanling piglet
To investigate the effects of weaning and weaning diet on the ecology of adherent Lactobacillus species in the gastrointestinal tract sixteen piglets were used. At 28 d of age four pigs were killed and served as the pre-weaning control (PW). Four pigs remained on the sow (Sow), four pigs were fed a …

Influence of Methionine on Growth and Nitrogen Balance in Weanling Quarter Horses
Twenty-four Quarter horse weanlings (120 d +/- 10 d) were blocked by age into 4 groups (n = 6) for a 56 d trial to evaluate the influence of methionine on growth and nitrogen retention. Weanlings were housed by block and individually fed 1 of 4 concentrate diets twice daily at 1.5% BW (as fed). …

Effects of Stress on Several Immune and Health Responses of Weanling Calves
The effects of weaning stressors on several immune and health responses were measured in three experiments. Sixty-four beef calves from 2 sources were bled on d - 7 (pre-weaning), 0 (weaning), 7, 14, and 21 (post-weaning). Serum selenium (Se), neutrophil and lymphocyte counts, and glutathione …

Changes in Conformation and Walk Kinematics of Suckling and Weanling Warmblood Foals
The objectives of these two studies were to characterize normal growth and resultant changes in conformation and walk kinematics of warmblood foals. The first study quantified linear and angular conformation changes of 13 warmblood foals during the first 9 mo of growth. An objective photographic …

Evaluation of high-protein canola meals fed to growing chicks and weanling pigs
… weights, bone ash, and blood characteristics of weanling pigs. Results indicated that ADFI was linearly (P < 0.05) decreased if inclusion of CMA, CMB, or CM-CV increased. Average daily gain of pigs fed CMA tended to increase quadratically, with the maximum response observed if 10 or 20% canola …

Effects of dietary melamine and cyanuric acid in young Pekin ducks and weanling pigs
… young Pekin ducks while the other involved weanling barrows fed contaminated diets for 21 consecutive days. Results indicate that [greater than or equal to] 1.00% MEL is needed to cause reduced performance in Pekin ducks and decreased body weight gain in barrows. In ducks [greater than or …

Sublethal Carbon Monoxide Toxicosis in Newborn Piglets and Weanling Pigs: Physiology, Behavior, and Performance
A total of two hundred eighteen pigs of two ages were used to determine the effects of elevated, sublethal atmospheric concentrations of carbon monoxide (CO) on physiologic, behavioral, and performance parameters.

Carbohydrate sources and maximizing the use of supplemental amino acids in diets for weanling pigs
… supplement (SNS) on growth performance of weanling pigs, and 2) to determine the maximum level of supplemental L-Lys, along with DL-Met, L-Thr, and L-Trp that can be added in diets for 6- to 12 and 13- to 23-kg pigs. Three experiments were conducted to compare the feeding value of MCP (20% …

Impact of Dietary Proteins on Growth Performance, Intestinal Morphology, and mRNA Abundance in Weanling Pigs
… mRNA expression in the brushborder membrane in weanling pigs. The results indicated that 6 % SDPP increased ADG and ADFI in the first 10 d after weaning (P < 0.05) without carry-over benefits in subsequent phases. There were potential additive effects of SDPP and Cu on growth promotion. Trends …

Immunomodulatory effects of whole yeast cells and capsicum in weanling pigs challenged with pathogenic escherichia coli
… capsicum, on performance and immune indices in weanling pigs inoculated with an F18, enterotoxigenic E. coli strain. Growth performance, fecal bacteria counts, frequency of diarrhea, clinical blood outcomes, intestinal cytokine gene expression, T cell profiles, and recall nitric oxide (NO) …

Acute Effects of Episodic PCB Congeners on the Hypothalamo -Pituitary-Thyroid (Hpt) Axis in Weanling Female Rats
These studies demonstrate that brief exposure to ortho-substituted PCBs can cause alterations in the HPT axis in immature animals. The data indicate that ortho-PCBs 95 or 101 cause secondary or pituitary-related hypothyroidism. There is also evidence that these PCBs may be affecting the HPT-axis …

The effect of soybean oil in starter diets on nursery air quality and performance of weanling pigs
Crossbred pigs 3 to 4 weeks of age were randomly assigned from outcome groups based on weight and sex to one of four dietary treatments either with or without added soybean oil or hulls. Nursery air quality was evaluated by measuring the concentrations of ammonia, carbon dioxide, settled dust, …
