“…The spermatological parameters in all rams were in accordance with the references [14,18]. The serum testosterone levels were similar with the results in references [12,[18][19][20]. The biochemical and enzymatic properties of blood serum in rams were in normal range and accordance with the references [1,8,13,15].…”

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.

“…The results of the effect of high ambient temperature on the blood glucose content of sheep are conflicting. In our study, the effect of HS reduced blood GLU value, Marai et al [ 54 ] found in Ossimi sheep that blood GLU levels were significantly higher in summer than in winter. Some other studies showed that blood GLU significantly decreased with different percentages (in Chios sheep and crossbred Chios × Ossimi) [ 53 ].…”

“…Similar to our findings, Salem et al [ 53 ] observed that serum TPROT levels were higher during hot summer than winter in Chios lambs and crossbred Chios × Ossimi in Upper Egypt, and ALB levels were higher compared with GLB. GLB levels were insignificantly altered by season (winter, summer, autumn) in Ossimi × Suffolk rams under Egyptian conditions [ 54 ]. HS is known to induce peripheral vasodilation to expel body heat and reduce blood flow to internal organs [ 55 ].…”

The aim of this research is to examine the influence of heat stress (HS) on body temperature (BT) measured rectally (RT) or by infrared thermography (IRT) of the nose (NT), eye (ET), leg (LT) and abdominal (AT) regions in intensively and extensively breed sheep and to detect a correlation between body temperature and metabolic response in sheep. A total of 33 Wurttemberg × Sjenica Pramenka sheep breeds were examined, 17 ewes were from outdoors and 16 were from indoor housing systems during three experimental periods (thermoneutral period, severe HS and moderate HS). Sheep under HS have a higher BT, and the magnitude of BT measured by infrared thermography (IRT) was higher than RT. LT and AT showed positive linear correlations with the temperature–humidity index (THI), while other ways of measuring BT did not give statistically significant correlations. Sheep under HS showed higher cortisol, insulin, total protein, albumin, urea, creatinine, bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, lactate dehydrogenase, creatine kinase and index of insulin resistance, with lower values of triiodothyronine (T3), thyroxine (T4), non-esterified fatty acids, beta-hydroxybutyrate (BHB), glucose, calcium, inorganic phosphates, magnesium and cholesterol. BT and metabolic response were different in the function of the housing method of sheep. LT and AT showed a significant correlation with almost all blood parameters, and the strongest connections were made with T3, T4, BHB and the revised quantitative insulin sensitivity check index of insulin resistance. The abdomen and legs are good thermal windows because LT and AT are good summative responses to external ambient THI and internal metabolic changes in sheep under heat stress.

“…Although there was no difference in globulin concentration of control and heat stressed group. Globulin level in blood plasma was insignificantly affected by season of the year (winter, summer and autumn) in rams under Egyptian conditions (Marai et al, 1992). Earlier studies in goats (Sejian et al, 2010) have also reported a significant decrease in total proteins, albumin and globulin concentration under heat stress.…”

Heat stress is one of the main factors which adversely affecting the animal welfare and thus the economic benefits of the farms. Goat husbandry in Egypt tends to breed throughout the year. However, a high ambient temperature is the major restriction on the animal productivity. This effect is provoked when heat stress is accompanied by high ambient humidity. This study was aimed to study the effect of heat stress on the physiological, some hematological and biochemical parameters. Twenty-five goats were exposed to the daytime (30 days) after an initial 7 day shading period, while another 10 goats were exposed to the shading regimen throughout the entire 30 days as a control group. Heat stressed goats showed the decrease of the feed intake, body weight and growth rate. Physiologically, the rectal temperature, respiration and heart rates were observed to be significantly higher. Moreover, the red blood cells count (RBCs), hemoglobin concentration (Hb), and packed cell volume (PCV) were significantly increased, whereas an insignificant change in white blood cells count (WBCs). Also, the serum total proteins, albumin, glucose, urea and creatinine levels were significantly decreased. On the other hand, cortisol level were significantly increased in heat stressed goats. Our results indicated that heat stress produced a significant alteration in the physiological, some hematological and biochemical parameters.
