The objective of this study was to investigate the protective effect of dietary natural sorbent-sodium humate (HuNa) on the prevention of aflatoxin B1 (AFB1) toxicity in the broiler chicken. Seventy-two (72) broiler hybrid Hybro birds were randomly divided into 4 groups: control group (G1) and 3 experimental groups (G2-G4) with addition of HuNa (G2); only AFB1 (G3) and HuNa; and AFB1 (G4). HuNa...

Two hundred and forty male Cobb broilers were used to study the reasons of causing ascites. The results showed that cold ambient temperature could induce ascites (33.89% vs. 2.50%) and significantly increase triiodothyronine (T3), but reduce thyroxine (T4) concentrations in plasma (p<0.05). The ascitic broilers had high concentrations of aldosterone and K , but low concentrations of T3 and T4 i...
This experiment was conducted to study the effect of different levels of levamisole on performance and related parameters with immune system in Cobb 500 strain male broilers. The experiment was carried out a completely randomized design, with 300 male broiler chickens in four treatments and five replicates 15 birds/replicates. The experimental groups consisted of zero, 2.5, 5 and 7.5 mg pe...
Utilizing a moderate rearing temperature regimen, two trials were conducted to determine the effect of dietary energy level on the amount of abdominal fat deposited when broilers are grown to equal body weight by varying growth time. The most abdominal fat (2.29% average of live weight for male and females) was produced by broilers offered a diet calculated to contain 3325 ME kcal/kg. The least...
in order to evaluate the effects of ascites on blood gas parameters and internal organ weights, 335 broilers related to parental lines was studied. one hundred sixty-one male broilers and one hundred seventy-four females selected randomly and studied under two treatments of control and ascites. at 54 days of age, body weight and body weight gain, feed intake and feed conversion rate between the...
A study was conducted to investigate the effects of thermostable phytase supplementation on the growth performance and nutrient digestibility of broilers for 42 d. 1-day-old Arbor Acres chicks with similar initial body weight were randomly divided into 3 treatments consisting 6 pens of 20 chicks per pen. The control group was given maize-soybean meal basal diet and the other two groups were fed...
