two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...

this study was conducted to evaluate the effects of different dietary levels of full fat safflower seed (0, 5, 10, 15 and 20% of diet) on performance, carcass characteristics and selected blood metabolites of broiler chickens from arbor acres plus strain. the experiment was designed with 350 commercial one-day-old male broiler chickens using completely randomized design with 5 dietary treatment...

This study examined the effects of various levels of dietary encapsulated choline chloride (ECC) on growth performance, carcass characteristics, serum and liver lipids content in Ross 308 broilers. A total of 480 day-old broilers were assigned to eight dietary treatments with six replicates of 10 birds each from 1 to 21 days of age. Eight experimental diets were provided from a basal non-added ...

this study was carried out to determine the effect of different levels of clove essential oil, as a natural growth promoter and probiotic on performance,carcass traits and serum components of broiler chickens. a total of 240 straight run day-old commercial broiler chicks (cobb 500) were distributed randomly into five groups. each group was subdivided into four replicates with 12 chicks each. th...

This study was carried out to evaluate the effect of different levels of garlic (Allium sativum) on growth survival and nutritional characteristics of goldfish (Carassius auratus). For this purpose, 180 goldfish with an average initial weight of 1.18± 0.08 g were introduced randomly into 12 aquaria (50×30×40 cm) in 4 groups, with 15 fish in each group. Treatments were fed on a basal diet for on...
