effect of l-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (ross 308) was investigated with three levels of l-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block design with 6 dietary treatments, four replicates and eight birds per each. broilers fed basal diet p...

an experiment was conducted in order to assess the effects of different levels of dietary canola meal (cm; 0, 10 and 20 %) and copper (0, 125 and 250 mg/kg) on performance, susceptibility to ascites syndrome and some blood metabolites of broiler chickens. during a six week period of experiment, a total of 495 male broilers (ross 308) were used in completely randomized design with a 3×3 factoria...

The present study was undertaken to investigate the toxic effects of higher doses (1,00,000 IU i.e. 2.5 mg/kg body weight (BW)) of vitamin D3, concomitantly with bacterial endotoxins (lipopolysaccharides: LPS) to study the immunomodulatory potential of vitamin D3 in IBL-80 broiler chicks. The chicks were divided into four groups [group I (NSS), group II (LPS), group III (Vit. D3 + NSS), and gro...

fifteen holstein male calves (416 ± 35 kg initial bw; mean ± sd) were employed in a replicated 3 × 3 latin square test to investigate the effect of partial replacement of barley grain by wheat factory sewage (wfs) within three 22-d periods including 16 d of adaptation and 6 d of data collection. the basal diet (wfs0) consisted of 42.5% (dm basis) barley grain, partially replaced with either 23....

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...

Glucagon-like peptide 1 is a compound known to cause reduced food intake in mammals, though its action on feed intake in fish is unknown. The clear differences in the effects of GLP-1 on mammalian and teleostean glucose homeostasis suggest that we cannot assume a similar action of GLP-1 on feeding in mammals and fish. In this study the effects and specificity of centrally administered GLP-1 on ...

Two experiments were conducted using four strains of Leghorn pullets, namely Babcock, DeKalb, H & N, and Shaver. Pullets were grown on conventional or low protein diets fortified with additional amino acids. At 18 wk of age, 64 pullets from each strain and diet treatment were transferred to individual laying cages, using eight replicate groups of four adjacently caged birds. In a second experim...

the effects of methanolic extract and leaf powder of artemisia annua were studied on performance, cellular and humoral immunity in 240 cobb broiler chicks in a completely randomized design. control group did not receive any treatment. the chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...

An inverse relationship between Ca intake and BMI has been found in several studies. It has been suggested that Ca affects adipocyte metabolism via suppressing 1,25-dihydroxycholecalciferol (1,25(OH)2-D3) and decreases fat absorption. We studied the effect of Ca and milk proteins (whey and casein) on body weight in C57Bl/6J mice. Male mice, age 9 weeks, were divided into three groups (ten mice ...
