Abstract
In this research 400 Ross 308 breeder fertile eggs were weighed At day 16 of incubation and evenly distributed into 4 treatments with 4 replicates per treatment and 25 eggs per replicate in a CRD design. On day 18 of incubation, 1 ml of an in ovo feed solution including: I) Carbohydrate (CHO), II) Amino ...

In this research 400 Ross 308 breeder fertile eggs were weighed At day 16 of incubation and evenly distributed into 4 treatments with 4 replicates per treatment and 25 eggs per replicate in a CRD design. On day 18 of incubation, 1 ml of an in ovo feed solution including: I) Carbohydrate (CHO), II) Amino acid (AA), and III) Butyric acid solution in 0.5% saline was injected into amniotic fluid of eggs. The control group remained non-injected. After injection eggs were transferred to hatcher. Upon hatch, chicks were weighed, sexed and transferred to the experimental house and reared to 42 days. At day two the midpoint of the jejunum was sampled for intestinal morphometric examination. The hatchability didn't differ significantly between treatments. Body weight and body weight to egg weight ratio of all in ovo injected hatchlings was greater than in controls (P

Abstract
This study was carried out to determine the effects of gamma irradiation on dry matter (DM) and on crude protein (CP) degradation of rapeseed meal, using nylon bags and SDS-PAGE techniques. Ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kGy were suspended ...

This study was carried out to determine the effects of gamma irradiation on dry matter (DM) and on crude protein (CP) degradation of rapeseed meal, using nylon bags and SDS-PAGE techniques. Ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kGy were suspended in the rumen of four non-lactating Holstein cows for up to 48 h. Intestinal crude protein digestibility was assessed using mobile nylon bag technique. Subunits of rapeseed meal proteins and disappearance patterns were traced and determined using sodium dodecyl sulphate polyacrylamid gel electrophoresis and densitometrical scanning. There were significant differences (P
