Endocrine Aspects of Oestrous Cycle in Buffaloes (Bubalus bubalis): An Overview
There is worldwide interest in buffalo as an animal for meeting the growing demands of meat, milk and work in the developing countries. One of the major constraints to full exploitation of the productive potential of buffalo has been its inherently low reproductive efficiency as reflected by late maturity, poor expression of oestrus, silent oestrus, irregular oestrous cyclicity, seasonality in ...
متن کاملPlasma concentrations of LH, progesterone and oestradiol during the oestrous cycle in swamp buffaloes (Bubalus bubalis).
Plasma concentrations of LH, progesterone and oestradiol were measured in 5 cyclic swamp buffaloes. Progesterone levels began to increase after Day 5 (Day 0 = the day of oestrus) and reached a plateau after Day 10. A rapid decrease in progesterone levels occurred during the 5 days before oestrus, followed by a sustained increase in oestradiol concentrations. Basal LH levels decreased towards th...
متن کاملFollicular dynamics and oestrous detection in Thai postpartum swamp buffaloes (Bubalus bubalis).
This study characterized follicular activity and oestrous behaviour from 5 to 9 days post-calving up to the 4th ovulation postpartum (pp) in 16 multiparous (range 2-7 parities) Thai swamp buffalo cows (Bubalus bubalis), aged 4-12 years and weighing from 432 to 676 kg. Ovarian follicular activity was examined by transrectal ultrasonography (TUS) every morning. Oestrous detection was performed tw...

متن کاملAn Observational Analysis of Secondary Sex ratio, Stillbirth and Birth Weight in Iranian Buffaloes (Bubalus bubalis)
Calving records of Iranian buffaloes from April 1991 to June 2010 comprising 1,151 herds with 34,911 calving events were used to evaluate reported secondary sex ratio, stillbirth, and calf birth weight. Logistic regression models were applied to analyze stillbirth and calf sex at birth, and statistical analysis of calf birth weight was performed using a linear mixed model. Overall, the ratio of...
