This study was aimed at evaluating the effects of different concentrations of the dietary plant extract supplement YGF251 (young growth factor) on growth performance, blood profiles, relative organ weight, nutrient digestibility and meat quality in broiler chickens. A total of 640 one-day-old male Arbor Acres broiler chickens with an average initial body weight of 40.25 ± 0.5 g were randomly al...

introduction: high environmental temperature during summer months which leading to heat stress, is of great concern in all types of poultry production. feed consumption, growth rate, hatchability, mortality, and other important traits governing the prosperity of the industry are adversely affected by severe heat stress. literature suggests that the advantages of dietary l-carnitine and ascorbic...

The present study investigated the effect of L-carnitine supplementation during pregnancy (125 mg/d) and lactation (250 mg/d) on milk production, litter gains and back-fat thickness in sows fed a low-energy and low-protein diet during lactation. Sows supplemented with L-carnitine produced more milk on days 11 and 18 of lactation (+18 %; P<0.05) and had higher litter gains during suckling (+20 %...

To examine the kinetics of carnitine palmitoyltransferase-I (CPT-I) and the influence of dietary variables, young pigs (18 kg, n 5 20) were fed corn-soybean meal diets supplemented with 40 g soy oil/kg and containing either 136 or 180 g crude protein/kg and either 0 or 500 mg/kg L-carnitine (2 3 2 factorial design). Diets were offered for 10 d (85% of ad libitum); CPT-I activities in liver and ...

The experiment was conducted to study productive, physiological and immunological parameters in Bandarah local chicks as affected by dietary organic selenium (SelPlexTM). All chicks were used in the present work produced from females and males fed diets with 0.0, 0.1, 0.2 and 0.3 mg Se / kg diet in the form of selenium yeast (Sel-PlexTM). Two hundred unsexed oneday old chicks (50 chicks per par...

The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...

A study was conducted to determine the effects of adherent Lactobacillus culture on growth performance, intestinal microbial population, and serum cholesterol level of broilers. Four dietary treatments, consisting of the basal diet (control), basal diet + 0.05, 0.10, or 0.15% Lactobacillus culture (LC), were fed to 2,000 Arbor Acres broiler chicks from 1 to 42 d of age (DOA). The chicks were ra...

SUMMARY Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa m eal at levels of 2, 3, 4, 5, 6, 9, O, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth d e-press ion was evident in comparable lots. In addition duplicate trials of four lots of n ewly hatched New H ampshire chicks...
