The aim of this study was to evaluate the effect of inclusion of tannic acid on some performance traits and nutrient digestibility in Holstein dairy calves. A total of 20 seven days old Holstein calves were randomly assigned to 4 experimental treatments with 5 calves each. The treatments were as follows: 1) basal diet formulated to meet all nutritional requirement of calves according to NRC (20...

We investigated the effects of dietary supplementation of zinc (ZnO; 0, 40, 80, 120 and 160 mg/kg) and Vit E (α-tocopheryl acetate; 0 and 40 IU/kg) on egg production, egg quality and Zn content of egg fractions and tissues in Japanese quails. Using a 5 × 2 factorial design, a total of 960 Japanese quails (Coturnix coturnix japonica) at day 70 of age were housed in cages and randomly assigned in...

The present study investigated the effect of Azomite (AZO) on growth performance, nutrient utilisation, and bone mineralisation broilers fed low protein diet. A total number 180 one-day-old male chicks were randomly distributed to three treatment groups having six replicates 10 birds each. Experimental diets included; positive control (PC) with 21.5% CP (starter) 19.0% (finisher), negative (NC)...

Abstract Intestinal flora is very important for improving the development of immune system in newborns. Maternal diet during pregnancy and lactation one key factors affecting growth offspring. The objective present study was to examine whether supplementation maternal with milk oligosaccharides Bifidobacterium could influence intestinal neonatal mice. In total, 30 pregnant Institute Cancer Rese...

Vitamin D and certain natural compounds have been shown to regulate both lipid metabolism and bone formation. Treatments that prevent or reverse age-related increase in bone marrow adiposity could both increase new bone formation and inhibit bone destruction. We tested the hypothesis that dietary supplementation with combinations of vitamin D and phytochemicals inhibits bone loss and decreases ...

this study was conducted to evaluate the effects of inclusion of monensin alone or in combination with methafix (a commercial product containing malate and fumarate) in the diets of lactating dairy cows on ruminal parameters and serum metabolites. four multiparous holstein lactating dairy cows (657± 12 kg of live weight; 133 ± 41days in milk) were assigned to one of the four dietary treatments....

Performance and Cu status were measured in growing and finishing steers supplemented with different copper (Cu) concentrations and sources. Sixty Angus (n = 36) and Angus x Hereford (n = 24) steers were stratified by weight and initial liver Cu concentration within a breed and randomly assigned to treatments. Treatments consisted of 1) control (no supplemental Cu); 2) 20 mg Cu/kg DM from Cu sul...

This experiment was conducted to investigate the effects of different supplementation levels palygorskite and probiotics complex (Pal-Pro) on laying performance, hatching egg quality, plasma antioxidative status, immune response broiler breeders. A total 432 Xuefeng black-bone chickens (42-week-old) were randomly assigned into four treatments with six replicates 18 hens. The breeders fed basal ...

Sheep were used to determine the effects of dietary supplementation with readily-fermentable carbohydrates on Mg, Ca, K and P utilization. In each of two metabolism trials, 15 mature, crossbred wethers (average weight, 49.2 kg) were allotted to five dietary treatments consisting of 800 g/d of orchardgrass (Dactylis glomerata, L.) hay alone, or supplemented with 450 g/d of either glucose, sucros...
