Ingestive activities of 100 stall-fed sheep (48 Muzaffarnagari and 52 1/4 Suffolk x 1/4 Dorset x 1/2 Muzaffarnagari) belonging to different age and class categories viz, lamb <3 months), young (5-6 months), hogget (9-12 months), pregnant, lactating and adult sheep, were recorded each minute under personal surveillance for 24 consecutive hours on three occasions. The experimental sheep were confined in a paddock (15.2 x 9.1 m) where ad.lib green fodder (lucerne/maize) and water were available to the animaIs aIl the time. Bout duration of eating, ruminating and drinking activity were recorded aIong with the inter-bout duration (the time interval between two consecutive bouts of a particular activity). The sheep spent 7 h day-1 eating, 2 h day-1 lying ruminating, 1 h day-1 standing ruminating and 5 min day-1 drinking. Time spent eating and drinking were more (p < 0.01) during daylight (0601-1800 hours), especially after sunrise and before sunset, than night time (1801- 0600 hours), whereas the trend reversed for rumination activity in which peak activity was noticed after midnight. Genotype and sex had no effect on the time spent on the ingestive activities but category of sheep varied significantly (p < 0.01). The mean duration of eating lasted 12 min while mean inter-bout interval among eating lasted 26 min. These intervals were aImost similar among aIl the sheep >6 months of age. Rumination bout in lying and standing posture lasted for 14 and 9 min, respectively and their recurrences occurred every 2-3 h. Rumination bout and inter-bout differed significantly (p < 0.05) between the categories of sheep and diurnaIly. Young, hogget and lactating sheep look significantly (p < 0.01) more drinking time than the other sheep. Each drinking bout lasted about 1 min and it recurred every 2 h throughout a 24 h period. The study suggests the practice of offering feed to stall-fed sheep at least three times a day (around 0600, 1300 and 1900 hours) to facilitate higher feed intake. ln the night, the sheep are to be provided with adequate space to ruminate in lying posture.
