Silent oestrus is an unsurmountable problem in the management of buffalo reproduction. In addressing this issue, we have earlier reported variation in the levels of urinary luteinizing hormone (LH) through the different phases of oestrous cycle with an extended window during the mid-oestrous phase. Based on this report, the present study is designed to assess the salivary LH levels in buffalo during the different phases of oestrous cycle. Bovine LH ELISA kit was used to determine the level of salivary LH. We observed a notable variation in salivary LH levels during the different phases of oestrous cycle. The maximum LH level, 39.07 mIU/ml, observed during oestrus, which was significantly (p < .05) higher than other consecutive phases. Altogether, the results showed a significant (p < .05) fold variation during oestrus compared with other phases. Therefore, the study convincingly shows that salivary LH has the potential of application in development of a modality for non-invasive oestrous detection in buffalo.

Context The adipose tissue produces adipokines - hormones essential to many biological functions, including reproduction. Aims We hypothesised that resistin, one of the adipokines, is present in the blood plasma, uterine luminal flushings (ULF) and uterus of pigs during the oestrous cycle and early pregnancy, and that resistin influences uterine steroidogenesis. Methods This study aimed to determine the expression of resistin in the porcine endometrium and myometrium during the cycle and pregnancy by quantitative real-time polymerase chain reaction and western blot (WB).

The coypu (Myocastor coypus bonariensis) is an annual polyestrous hystricomorph rodent with variable-length oestrous cycles, which ovarian histoarchitecture during this period is not fully described. This study analyses variations in ovarian morphology during the oestrous cycle, focusing on follicular development and atresia. Eighteen sexually mature virgin females aged 7-9 months, weighing 4.
