Two experiments were conducted to examine the effects of dietary inclusion of xylose on growth performance, nutrient digestibility and xylose absorption in the portal-drained viscera of broiler chicks. In Exp. 1, ninety male 14 day-old broilers were used to study the effects of different inclusion levels (0, 5, 10, 20 and 40%) of D-xylose in the semi-purified diets on the growth and nutrient di...

A total of 600 avian male broilers at the age of 1 d were used to investigate the effects of cysteamine (CSH) on growth performance, digestive enzyme activities, and concentrations of serum hormones. The broilers received the same basal diets, with CSH added at 0 (control), 60, 90, 120, or 150 mg/kg. The feeding program consisted of a starter diet until 21 d and a grower diet until 42 d. The br...

The training regimens of modern-day athletes have evolved from the sole emphasis on a single fitness component (e.g., endurance athlete or resistance/strength athlete) to an integrative, multimode approach encompassing all four of the major fitness components: resistance (R), interval sprints (I), stretching (S), and endurance (E) training. Athletes rarely, if ever, focus their training on only...

Preventing leg disorders in broilers, without changing their body weight at slaughter age and their rearing time is a challenge for poultry production. The method of prevention we studied consisted in alternating the distribution of different diets. This kind of diet schedule is called “sequential feeding”. The alternation of poorand rich-lysine diets was used in order to reduce early growth an...

A total of 420 fertile broiler eggs (Cobb) with uniform egg weight were collected and divided into three groups: non-injected control, injected control (0.5 ml of 0.9% normal saline) and arginine (0.5 ml of 0.5% arginine); and injected on 18 day (d) of incubation into amnion. On the 21 d, 108 chicks were randomly selected from each treatment totaling to 324 chicks. The hatchability, hatch weigh...

The experiment aimed to study the effect of post-hatch early held feeding times starter supplemented with egg yolk and white on growth performance, viscera development and immune response in broiler chickens. The working hypothesis was based on the fact that better development of the gastrointestinal tract and immunity system in the first week of the chicks' life affects positively the growth p...

Abstract This study was conducted to investigate the effect of dry kitchen waste meal (KW) as a partial replacement for maize on growth performance, nutrient digestibility and carcass characteristics broiler chickens. A total 160 chicks were used study. The randomly assigned four dietary treatment groups T1, T2, T3 T4 40 birds each with 10 per replicate in completely randomized design (CRD). la...

background: growth promoters are chemical and biologicalsubstances that are added to livestock food with the aimto improve the growth of chickens in fattening and the utilizationof food, and in this way achieve better production and financialresults. objectives:an experiment was conducted to evaluatethe effects of enzyme complex, probiotic, and their combinationon performance of broilers fed a ...

Two 42-d experiments compared the nutritional value of YieldGard Rootworm corn (MON863; experiment 1) and YieldGard Plus corn (MON810 x MON863; experiment 2) to their respective nontransgenic controls and 6 commercial reference corn hybrids when fed to growing broilers. For each experiment, a randomized complete block design was used with 8 dietary treatments in each of 5 replicated blocks of p...
