An experiment was conducted to evaluate the effects of replacement of barley grain with barley hydroponic fodder on blood metabolites and milk production of lactating Saanen goats. Eight dairy goats (45± 1.5 kg of live body weight and 3 months of lactation (88±6 days in milk)) were allocated to 4 experimental diets including the control diet and diets consisting of 37, 66 and 100 percent replac...
in a 3×3 latin square design three treatments including: 1) basal diet (control) in addition to diets containing 2) 100 and 3) 200 mg/day of peppermint essential oils were tested in three ruminally cannulated male sheep with average body weight of 50±3 kg. rumen liquor was sampled 3 hours after feeding to determine rumen ph, n-nh3 and volatile fatty acids. on the last day of each period, blood ...
changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...
Two experiments were conducted to evaluate the effects of irradiated ingredients in meal and pelleted diets on nursery pig performance. In Exp. 1, a total of 192 pigs (initial BW, 6.0 kg) were used in a 25-d experiment. Pigs were blocked by BW and randomly allotted in a 2 x 2 factorial arrangement of treatments with main effects of diet form (meal or pellet) and either irradiated (11.92 kGy) or...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
1. To examine the relations between short- and long-term regulation of food intake in calves given milk-substitute diets, abrupt changes were made in the dry matter (DM) concentration of the diet (Expt 1) and in the frequency of feeding (Expts 2 and 3). 2. When calves, fed once daily, had the DM concentration of their diet changed, they drank the same volume of milk on the 1st day they received...
A study was conducted in a completely randomized design to evaluate the effect of diets formulated on the basis of four critical essential amino acids (lysine, methionine, tryptophan and threonine) on the crude protein requirement, carcass quality, nutrient digestibility, haematological and blood biochemical indices of broiler finisher chickens (28-56 days) reared under tropical environment. On...
Considering the role of arginine in the prevention of ascites and the possibility of replacing this amino acid with Guanidinoacetic acid (GAA), in present study, the effects of different levels of GAA (0.5 and 1 g/kg diet) supplementation in low-protein diets on growth performance and ascites incidence in broiler chickens were investigated. Therefore, a total of 208 male broilers (Ross 308...
The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...
