Relationship Between Some Reproductive Parameters and Biochemical Properties of Blood Serum in Rams

Abstract

The objective of the present study was to describe the relationship between some reproductive parameters, hormonal levels, and some biochemical properties of blood serum in rams under the Afyon province conditions. The total protein and globulin were positively (P < 0.01) correlated with sperm motility and sperm concentration in all of rams. Total lipid was negatively (P < 0.05) correlated with sperm motility and concentration in Daglic, and it was positively (P < 0.01) correlated with percentage of abnormal spermatozoa in Chios rams. Total lipid and cholesterol was positively (P < 0.01) correlated with triiodothyronine in all of rams and was negatively (P < 0.05) correlated with testosterone in Daglic rams. Percentage of abnormal spermatozoa were negatively (P < 0.01) correlated with alanine amino transaminase (ALT) level, but were positively (P < 0.01) associated with aspartate amino transaminase (AST) level and AST/ALT ratio in all of rams.

Seasonal effect on the scrotal circumference, concentration of testosterone and some biochemical parameters in Nuaimie breed rams in Salah-din province

“…seasonal fluctuations of glucose concentration in rams were observed (table 2), the highest concentration was recorded in winter and autumn (81.8±3.753 and 68.7±2.381 mg/ml respectively) and significantly (P≤0.05) decreased in spring and summer (34.8±1.652 and 36.4±1.529 mg/ml respectively), similar results were observed by (31) and this rise in glucose level in winter may be related to inhibition of insulin secretion due to the low nutrition because cold stress (32). The findings of the present study showed (Table 1) that the concentration of cholesterol (53.37±2.836 mg/ml) was higher than recorded by (27,33) in Chios, Daglic and Yankasa rams (35.9, 32.6 and 45.04 mg/ml respectively), while it was lower than recorded by (27) in Ouda rams (63.06 mg/ml). This variation may be due to differences in breed (33).…”

On the other hand, significant effect of season on the cholesterol concentration in Nuaimei rams was observed in the current study ( Table 2).…”

Activity and Content of Isozymes of Aspartate Aminotransferase in Connection With the Survival of Bull Spermatozoa

“…Активність аспартатамінотрансферази проявляється у спермі плідників. Встановлено, що величина активності ензиму в еякулятах, поряд з іншими показниками, може служити маркером запліднювальної здатності сперміїв (Nizański et al, 2001;Kozdrowski, & Dubiel, 2004;Gündoğan et al, 2004;Gaczarzewicz et al, 2010). Тому метою роботи було вивчити активність та вміст ізозимів АСТ в еякулятах бугаїв у зв'язку з виживанням сперміїв.…”
