To compare the relative value of the fish meal and the cottonseed meal in highly fermentable diets (40% forage and 60% concentrate with), eight cows were assigned randomly to diets with 0, 1.5, 3 and 4.5 percent of the fish meal. In the first experiment, the degradability of dry matter and crude protein of the fish meal, the cottonseed meal and concentrate in diets was estimated with different ...
The present study was conducted to determine the appropriate level of protein in diet of Cyprinus carpio fry based on biofloc technology. The experiment was designed based on triplicate of four bioflocs treatments (BFT) and one control treatment (CW). 450 specimens of C. carpio fry with mean weight of 17±0.08 g were stocked in 15 fiberglass tanks. Fish were fed in biofloc treatments with diets ...
Background and purpose: Vipera lebetina lives in different areas in Iran, and its venom contains a variety of proteins with coagulant and anticoagulant activities. Fibrinolytic enzymes could have a therapeutic role in dissolution of blood clots, so, this study aimed at separating the venom components of Iranian V. lebetina and detecting its anticoagulant activity. Materials and methods: In thi...
the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...
The study was conducted with a completely randomized design consisting of four treatments in triplicates. Experimental diets were formulated to contain four different lipid levels (8, 10, 12 and 14%) at constant protein level (46.8%) and different gross energy of 4314, 4417, 4519 and 4622kcal/kg, respectively. Kutum fry (average weight, 203±4mg) were randomly assigned and distributed at a densi...
Objective. The effect of extracted crude soybean saponins on preneoplastic lesions, aberrant crypt foci (ACF), and the related mechanism were investigated. Research Methods and Procedures. Rats were assigned into five groups according to different doses of extracted crude soybean saponins and received 1,2-dimethylhydrazine (DMH) injection in week 5. In week 15, all rats were sacrificed. The num...
Forages and crop residues are inexpensive and easily available feedstuffs for feeding grasscutters in captivity. These feedstuffs are nutritionally poor, not balanced for optimum performance and, therefore, required supplementation. Protein requirement of growing grasscutters was determined using thirty two 10-weeks old male grasscutters of equal weights. The grasscutters were separated into fo...
Applicability of the TOBEC method (electrical conductivity) was tested for the in vivo determination of different egg components and for the separation of eggs with different composition. Altogether 300 hen’s eggs – originated from a 36 weeks old ROSS-308 hybrid parent stock – were measured by TOBEC, and the extreme and average 5-5% – based on the measured values – were chosen for chemical anal...
It was found that the partially purified beta-ketoacyl-ACP synthase of Bacillus insolitus did not require the addition of FabD (malonyl-CoA:ACP transacylase, MAT) for the activity assay. This study therefore examined the necessity of FabD protein for in vitro branched-chain fatty acid (BCFA) biosynthesis by crude fatty acid synthetases (FAS) of Bacilli. To discover the involvement of FabD in th...
