this study was conducted to investigate the effects of dietary nigella sativa meal (nsm) on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in japanese quail. for this purpose 300 one-day old japanese quail chicks in a completely randomized design was used with five treatments in four replicates )containing 15 birds each(. the experimenta...

this study was evaluated to study the effects of vitamin c and the bacteria bacillus subtilis, b.lichniformis on growth and carcass composition of litopenaus vannamei. three treatments were applied, treatment fed with probiotics (4×1010 cfu/kg food), treatment with vitamin c (140 mg/kg food) and the control group. three replicates were used for each treatment. shrimps were kept in nine 300-lite...

Alloxan-diabetic rabbits develop hypercholesterolemia and hypertriglyceridemia in response to cholesterol feeding. To determine whether alterations in apolipoprotein composition of plasma lipoproteins were due to changes in apolipoprotein gene expression, we measured the steady state apoE mRNA levels in several tissues from both control and diabetic rabbits. Control rabbits were fed either chow...

The objective of this research was to evaluate changes in the muscle conformation of subprimal top-loins (M. longissimus lumborum) from calf-fed Holstein steers fed zilpaterol hydrochloride (ZH). Top-loins (n = 100) were transversely cut into 2.54 cm-thick steaks, weighed, and objectively evaluated via image analysis software for muscle area, width, and length traits. Top-loin steaks from steer...

this research was conducted to evaluate the effects of synthetic methionine replacement with herbal methionine (hm) on performance, blood biochemical parameters and carcass characteristics in broiler chicken. a total of 280 8-old ross 308 male chicken were randomly assigned to 7 dietary treatments: control, in which 100% methionine requirement was supplied form dl-methionine, and in treatments ...

Aquaculture needs to provide live food such as Artemia and one of the most important issues in A. franciscana rearing, is a food supply. The instar I nauplii were fed in seven treatments including Wheat bran, Rice bran, Soy-meal and algae (Dunaliella salina). For each treatment calculated growth rate, survival percentage, and body composition. At the reproductive period, 35 pairs were individua...

An optimum dietary carbohydrate content is important for maximum fish growth. In this study, we fed Wuchang bream (Megalobrama amblycephala) with either control diet (30.42%) or high carbohydrate diet (52.92%) for 90 d. Fish were fed to apparent satiation three times daily in an aquarium with automatic temperature control and circulated water. Growth performance, plasma biochemical parameters, ...

The effects of feeding zilpaterol hydrochloride (ZH) and shade were evaluated on blood metabolites in finishing beef steers ( = 480). Cattle were fed 0 or 8.33 mg/kg of diet DM ZH for 21 d with a 3- or 4-d withdrawal before harvest and were housed in open or shaded pens. Blood samples were collected the day before ZH was fed and on the day the cattle were shipped to the commercial abattoir. Lac...

Holstein steers (n = 2,275) were assigned to 1 of 3 treatments: 1) a control diet containing no β-agonists, 2) a diet that contained zilpaterol hydrochloride (ZH; 8.3 mg/kg [100% DM basis]) for 20 d with a 3-d withdrawal period before harvest, and 3) a diet that contained ractopamine hydrochloride (RH; 30.1 mg/kg [100% DM basis]) for 28 d before harvest. No differences (P ≥ 0.18) were detected ...

Twenty-four newborn Holstein heifer calves were fed 1 of 4 milk replacers (MR): control (20% CP, 21% fat; MR fed at 441 g/d); high protein/low fat (HPLF; 28% CP, 20% fat; MR fed at 951 g/d); high protein/high fat (HPHF; 27% CP, 28% fat; MR fed at 951 g/d); and HPHF MR fed at a higher rate (HPHF+; 27% CP, 28% fat; MR fed at 1,431 g/d). Dry calf starter (20% CP, 1.43% fat) composed of ground corn...
