The objective of the following experiments was to examine the effect of dried distillers grains plus solubles (DDGS) supplementation of calves grazing bermudagrass (Cynodon dactylon) pasture during summer (Exp. 1) or fed lowquality tall fescue hay (Exp. 2, Festuca arundinacea) during winter months. In Exp. 1, a total of 36 steers (261 kg) were randomly assigned to one of nine 0.81-ha pastures r...

Aim of this work was to evaluate if long-term dietary supplementation of potassium iodide (KI) to dairy goats can influence metabolic and hormonal parameters. Thirty Sarda crossbred dairy goats were divided into three groups, which were orally administered 0 (control group; CON), 0.45 (low iodine group; LI) or 0.90 (high iodine group; HI) mg of KI/day, respectively. The daily dose of KI (76.5% ...

BACKGROUND Regular moderate intensity physical activity and lipid lowering effects of Nigella sativa (N. sativa) supplementation may be appropriate management for sedentary overweight females. Therefore, the aim of the present study was to examine the effects of long-term N. sativa supplementation and aerobic training on lipid profile and maximal oxygen consumption (VO2 max) in sedentary overwe...

Finishing Holstein young bulls exclusively on pasture generally results in very lean carcass and meat, but corn supplementation is expected to simultaneously improve carcass traits and intramuscular lipids (IML). The expected increase in IML would allow for a larger 18:2c9,t11 (CLA) deposition in meat without affecting the n-3 PUFA present in LM phospholipids (PL). Holstein bulls (n = 33) with ...

The purpose of this study was to compare the effects of l-citrulline (Cit) and l-arginine (Arg) supplementation on nitric oxide (NO) biomarkers, pulmonary O2 uptake (V̇o2) kinetics, and exercise performance. In a randomized, placebo (Pla)-controlled, crossover study, 10 healthy adult men completed moderate- and severe-intensity cycling exercise on days 6 and 7 of a 7-day supplementation period w...

The effect of combined feed supplements (prilled fat, sweetener and toxin binder) was studied on 24 apparently healthy early lactating rural and urban maintained Murrah buffaloes. The feeding of combined feed supplement was carried out for a period of 90 days. DMI, BCS, body weight were recorded at fortnightly intervals and milk composition was analyzed at weekly intervals. Blood samples were a...

Pressor and heart rate changes following change in posture without or with L-arginine supplementation (1g/day for 6 weeks) were studied in 28 sickle cell anemia (SCA) and 32 non-sickle cell anemia (NSCA) subjects. Change in posture increased HR (p<0.01), RPP (p<0.05) in both groups of subjects, MABP (p<0.05) in SCAS but reduced MABP (p<0.01) in NSCAS and PP (p<0.01) in SCAS. L-Ar...

A total of 50 weaning pigs (16 d of age; 4.72 +/- 0.23 kg of BW) were selected to investigate the effect of dietary chito-oligosaccharide (COS) supplementation on growth performance, fecal shedding of Escherichia coli and Lactobacillus, apparent digestibility, and small intestinal morphology. Pigs housed in individual metabolic cages were assigned randomly to 5 treatments (n = 10), including 1 ...

Lactoferrin has antimicrobial activity associated with peptide fragments lactoferricin (LFC) and lactoferrampin (LFA) released on digestion. These two fragments have been expressed in Photorhabdus luminescens as a fusion peptide linked to protein cipB. The construct cipB-LFC-LFA was tested as an alternative to antimicrobial growth promoters in pig production. Sixty piglets with an average live ...

BACKGROUND Because both micronutrients and antimicrobial peptides protect against diarrhea, we looked for an effect on intestinal antimicrobial peptide gene expression during a randomized controlled trial of multiple micronutrient (MM) supplementation. METHODS Consenting adults (n=287) in Lusaka, Zambia, were randomized to receive a daily MM supplement or placebo and were followed up for 3.3 ...
