Seasonal effects on Growth, Physiology, Hematology and Biochemical Profiles of Naeemi Sheep Breed

Abstract

Improving farm animal performance resilience may help alleviate harsh weather and seasonal fluctuations while also maintaining the long-term viability of livestock farming as future climate challenges become more apparent. We generate new seasonal resilience phenotypes in this study, which indicate production performance and metabolic changes in response to changing weather. We examine the impact of calendar season (summer and winter) on animal performance resilience by assessing various parameters of ewes, lambs, pregnant, male, and lactating Naeemi breed animals from the Agriculture Research Station; Kuwait Institute for Scientific Research, Kabd. The evaluation of biochemical and hematological parameters over time revealed a probable environmental effect on animal health. According to the findings, all of the hematological and biochemical indicators are within normal limits. The hematological data revealed that WBCs and RBCs vary by type and season (WBCs: 7.1–9.9 (x103/μl), and 5.2–7.9 (x103/μl); and RBCs: 8.7–11.6 (x106/μl), and 10–10.8 (x106/μl), respectively). The MCH values (11.7–12.9 pg) are above the normal range, which is linked to two other factors: mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) are both above the usual ranges of 25.6–31.8 fL and 14.8–45.9 g/dl, respectively. During the winter, dry ewes’ total protein and hemoglobin levels are significantly greater (P<0.05) than other types of sheep, according to a biochemical investigation. The results showed that the physiological, biochemical, hematology analysis and production performance of Naeemi sheep were affected by the seasons and stage of production and growth
