The effect of seasons on behaviour during milking in buffaloes (Bos bubalis)

An investigation on behaviour during milking involving 200 buffaloes was carried out to study the effect of climate on milking behaviour for a period of four years. The results obtained were: (1) In extremely docile animals (temperament score I) the mean distribution was least (33.5) in hot-dry summer as compared to winter (39.2) and hot-humid summer. (2) The number of buffaloes milked after oxytocin injections was maximum (11.1%) during the hot-dry summer against other seasons for the temperament score I over temperament scores III and IV, where all buffaloes were milked with oxytocin injections. (3) The mean flow rate was least in hot-dry summer in each temperament score. (4) Milking time was higher in all the temperament scored buffaloes during the hot-dry summer than during the other seasons. It is concluded that as environmental temperature increases, there occurs an increase in thermal stress, the milking behaviour changes and animals become more hostile and excited which leads to a decrease in milk production.
