The present study was performed to determine the effect of resistant starch as a type of prebiotic and phenolic compound extract on performance, hematological and blood parameters of suckling Holstein calf. For this, 54 suckling Holstein calves (27 male and 27 female) were randomly assigned in 9 treatments including: RS1 (8 g resistant starch), RS2 (16 g resistant starch), PE1 (1800 mg phenolic...
This experiment was carried out to determine the nutritional value and the effect of different levels of tomato seed and pomace on performance of broilers. Corn grains and soyabean meals were replaced by tomato seed at levels of 6, 12 and 18 % and tomato pomace at levels of 3, 9 and 12 %. At first, the metabolizable energy of tomato seed and pomace was determined by the Sibbald method. In this ...

In a 2×2 factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietary calcium (Ca) to phosphorus (P) ratio in phytase-supplemented feeds with a marginal P concentration has a positive effect on bone mineralization. The four experimental diets, which contained 0.4% ...
the aim of this study was to recognize the effects of dietary hempseed (hs) and hempseed oil (ho) on performance, egg quality and blood parameters of laying hens. a total of 320 hy-line 55-weeks laying hens were randomly allotted to eight dietary treatments with five replicates (8 birds each). the experimental treatments were offered as a completely randomized design as follow: control group (n...
This experiment was conducted to investigate the effects of intensity of restricted early feed and increased nutrient density after restriction period on performance and compensatory growth in broilers. Two hundred and eighty-eight broiler (Lohman) chicks in a completely randomized design in a 2*3 factorial arrangement of treatments were employed. Birds were fully fed from 7 to 13d or 100% of a...
Inorder to evaluate the effects of four sources of fiber (soy hulls, barley hull, rice husk and corn husks) each with two particle size (with 1 and 2- mm of geometric mean) on performance, nutrient digestibility, some blood parameters, small intestine morphology and secum bacteria in broiler chicken, 540 Ross308 broiler male chicks from 1 to 42 days were used in a completely randomized design w...
to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...
Three-hundred and twenty 7-day-old Ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin B 1 (AFB1) from 7 to 28 days of age. Sodium bentonite (0.5%), yeast (Saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (HSCAS) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...
the objective of this study was to assess the importance of strain and sex and their interaction effect on broiler chickens’ performance and susceptibility to ascites. chicks from three strains (ross 308, cobb 500 and arian, labeled as a, b and c respectively) were obtained from the same age breeder and sexed when one-day-old. each crosses’ sex was assigned to four pens of 60 broilers each. bod...
