Blood biochemical profile in sub-oestrus buffaloes

Author(s): Abhishek Bisen, Satya Nidhi Shukla and Aditya Mishra
Abstract: Normal reproduction is a primary and inevitable basis for sound animal husbandry enterprise and is one of the most important considerations determining the profitability. However, buffalo is considered as the animal of poor reproductive efficiency due to several features including delayed puberty and sexual maturity, sub-oestrus, anoestrus, true anoestrus and seasonality in breeding. Ovarian disorders are the most important causes of infertility characterized by cessation of sexual cycles and psychic manifestation of oestrus in dairy animals. Anoestrus is a functional disorder of ovaries causing lowered fertility in dairy animals especially in buffaloes. It is responsible for tremendous economic losses to the farmers by decreasing calf crop and milk production. True anoestrus (smooth ovaries) and sub-oestrus (functional ovaries) are the most common forms of postpartum anoestrus remain undiagnosed in field conditions and are responsible for prolonged calving interval and culling at breeding age in these animals. The intensity of oestrus signs in buffaloes is generally weak and also mounting activity is not pronounced as in cattle. Summer anoestrus is an important condition contributing to infertility in buffaloes. Heat stress causes increased cortisol secretion which blocks oestradiol induced sexual behavior. Deficiency of trace minerals especially calcium, phosphorus and magnesium also influence the ability of animals to utilize other micro-minerals. The influence of these minerals on certain enzyme system may affect reproductive efficiency. In the present study blood biochemical profile in sub-oestrus and true anoestrus buffalo (n=12 each) were compared on day 0, 7, 14, 21 and 28 irrespective of stage of estrus cycle. The mean serum manganese and zinc was recorded significantly higher in cyclic as compared to non-cyclic buffaloes on different days of cycle. However, mean serum copper was higher on day14 and 28 in cyclic as compared to non-cyclic buffaloes. The mean serum calcium, phosphorus, their ratio and cobalt was recorded non significantly higher in sub-oestrus buffaloes as compared to non-cyclic buffaloes.
