A galacto-oligosaccharide (GOS) prebiotic was prepared by reacting a high concentration of lactose (40% wt/vol) with a beta-galactosidase enzyme for 24 h at 37 degrees C. The enzyme was produced from recombinant Pichia pastoris X-33 cells. The study aimed at evaluating the effects of the prebiotic, a Bifidobacterium lactis-based probiotic, and the combination of these dietary additives on BW, f...

The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...

The objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in Holstein dairy cows. Four multiparous Holstein dairy cows (665 ± 25 kg BW, 170 ± 7.0 DIM and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 Latin Square design with 28-d periods. Corn starch and sucro...

The objectives of the current study were to evaluate the effect of feeding diets containing 0, 10, or 20% distillers dried grains plus solubles (DDGS) to laying hens (21 to 26 wk of age) on emissions of NH3 and H2S. Hy-Line W-36 hens (n = 640) were allocated randomly to 8 environmental rooms for a 5-wk period (hens in 3 rooms were offered the 10% and 20% DDGS diets each; hens in 2 rooms were of...

Vitamin D is a commonly prescribed, fat-soluble vitamin important for calcium homeostasis and bone health. Toxicity (VDT) rare typically caused by aggressive supplementation or manufacturing errors. In epidemiologic studies, levels correlate inversely with adiposity, dietary weight loss associated increases in 25-hydroxyvitamin [25(OH)D] level. stored adipose tissue it postulated that risk fact...

________________________________________________________________________________ Abstract The distribution of chlorocholine chloride (CCC) residue or its metabolites in the meat and eggs of laying hens was studied using the N delta value (δN) and N atom % derived from N-CCC containing diets. In a completely randomised design, 20 laying hens were divided into four groups allocated four different...

Indian River male broiler chickens growing from 7 to 30 d of age were fed on diets containing crude protein levels ranging from 120 to 300 g/kg plus 0 or 1 mg triiodothyronine (T3)/kg diet. The purpose of this study was to examine the effects of these treatments on lipogenesis after a common diet was fed (180 g crude protein/kg diet from 30 to 56 d of age). Dietary treatment groups were sampled...

We investigated the impact of Zn status on the maintenance of mucosal homeostasis. Rats were fed diets containing different amounts of Zn (30, 10, 5, <1 mg Zn/kg diet) for 21 d. Serum Zn concentrations were lower in rats fed marginally Zn-deficient (MZD; 5 mg Zn/kg diet) and severely Zn-deficient (<1 mg/kg) diets but not in those fed the marginally Zn-adequate diet (10 mg/kg) or the Zn-adequate...

BACKGROUND Epidemiologic studies suggest a low incidence of cardiovascular disease in populations that consume dietary soy. For people aged 40 to 70 years, each increment of 20 mm Hg in systolic blood pressure (BP) or 10 mm Hg in diastolic BP doubles the risk of cardiovascular disease for BPs of 115/75 to 185/115 mm Hg. METHODS To determine the effect of soy nuts on systolic and diastolic BP ...

True ileal lysine digestibilities were determined using the homoarginine (HA) method in casein-, barley-, canola meal-, and barley-canola meal-based diets fed to growing pigs. Four Yorkshire barrows (25 to 49 kg BW) equipped with ileal T-cannulas were fed one of the diets according to a 4 x 4 Latin square design. All diets, except for the barley diet, were formulated to be similar in DE:CP rati...
