The effects of five levels of dietary protein and energy on ostrich performance during hot season were evaluated in this study. Five males and 10 females of healthy mature ostriches (Struthio camelus) were randomly assigned equally into five nutritional groups A, B, C, D and E, each of 1 male and 2 females. Birds were fed (16% protein +2800 kcal) , (17% protein + 2900 kcal ) , (18% protein + 30...

The effects of supplementing a basal diet with 2 levels of an essential oil mixture and an antibiotic on the growth, laying traits, and egg hatching characteristics of broiler breeders were examined in this study. Nine hundred sixty female and 128 male breeders at an age of 1 d old were randomly allocated to 16 replicates (i.e., 4 replicates of 4 dietary treatments) in a floor pen trial. Two le...

In this study, the effects of pre-storage coating different ratios gum arabic on hatching traits and chick growth performance were investigated. Treatment groups; eggs treated with 5% stored for 7 days (7-5G), 14 (14-5G), 10% (7-10G) applied (14-10G). After application, at 13 °C 75% humidity or days. a total 800 used, 200 in each four groups. Regardless have less egg weight loss than (P<...

Reliance on seasonal wild harvests of the edible long-horned grasshopper Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) needs to be broken through developing efficient mass rearing protocols. This study aimed at boosting productivity laboratory colonies R. understanding ways minimising cannibalism, selecting suitable oviposition substrates and enhancing egg development hatchability. ...
