Investigations on the determination of milk yield and composition in sows


, : Investigations on the determination of milk yield and composition in sows. Agrobiological Research 43(3): 191-199

Milk yield was determined in 7 sows at hourly intervals on 4 consecutive days, beginning on day 5, 9, 12, 14, 17 or 19 of lactation, by means of weighing the piglets. On day 1, 2, 3 and 4, hourly milk yield averaged 239, 238, 255 and 268 g resp., the differences of days 1 and 2 from days 3 and 4 being significant. The correlations between hourly milk yield and daily yield were 0.93-0.97.
