Awassi is a multi-purpose sheep breed. Awassi lambs being finished are usually offered an 18% crude protein (CP) diet. The growth rate of Awassi lambs is lower than other meat breeds. Therefore, this high content of dietary CP is questionable. The objective of this study was to estimate the optimum CP level for finishing Awassi lambs. Fifty male Awassi lambs (23.0+/-1.2kg) were fed five high co...

The study was conducted to detect haptoglobin in seminal plasma (SP-Hp) of Awassi rams and the effect of the breeding season on its concentration, along with determining the correlation with its concentration in serum (S-Hp) and main semen variables. Pre-warmed artificial vagina was used to collect semen samples biweekly from five Awassi rams. Semen samples were evaluated for volume, concentrat...

The objective of this study was to focus the light on the events of angiogenesis during spring and summer times. For this purpose, testes of ten rams were collected from Baghdad in spring and summer seasons in 2017.Samples were histologically processed and prepared for light microscopy. Hematoxylin and eosin stain was used for staining. The results revealed that the process of angiogenesis was ...

The antioxidant ability of vitamin B12 (VitB12) and its effects on motility characteristics fresh chilled ram spermatozoa were investigated. Three concentrations VitB12 including 1, 2 4 mg/ml added to tris media samples collected from five Awassi rams incubated in these at 37 5 °C for 24 hours respectively. Formation hydrogen peroxide (H2O2) was estimated using a fluorometric assay analyzed com...

The effect of rumen-protected methionine (RPM) was investigated in Awassi ewes (0, 3 or 5 g/head/d, n = 20) on reproductive and productive performance (initial body weight [BW] 70.9 − 71.8 kg, years). Supplementation started with the flushing feeding regime (at breeding time) lasted for 42 d. RPM reused during last 60 d pregnancy first lactation. increased (p < .05) progesterone concentration a...

The objective of this study was to determine the effect of castration on penile and urethral development in Awassi lambs. Twenty 1−2-weeks old Awassi lambs were divided randomly into 4 groups. Groups 1, 2, and 3 were castrated at 2 weeks, 3 and 5 months of age, respectively. Group 4 was not castrated (control). To assess penile and urethral development, penile length, penile diameter and urethr...
