| Abstract | ||
| 425 oestruses exhibited by 178 Black Bengal goats of different parities (Nulliparous, Primiparous & Pluriparous) during three seasons viz: winter (November-February), summer (March-June) and monsoon (July-October) were analysed to study th effect of parity, season, month and interaction of parity with season and month. The overall duration of oestrus was 33.94+0.66 h. ranging between 5 to 60 h. The effect of month, season and interactions of parity with month and season were significant on duration of oestrus in these goats. Duration of oestrus during monsoon was significantly more (36.21+0.98 h) than that of winter (31.78+1.08 h) and summer (31.84+1.40 h) which did not differ significantly among them-selves. The overall incidence of short (/ 20 h), medium (20.1-40.0 h) and prolonged oestrus (40.1-60.0 h) was 19.06, 50.35 and 30.95% respectively. The effect of season and parity was significant on the incidence of short, medium and prolonged oestrus. | ||
