Abstract: In Merino lambs, that were prevented from sucking by a cover over the maternal udder, the proportion of time spent in attempting to reach the udder and suck declined from about 30 per cent during the first 2 or 3 hr of life to less than 5 per cent by 12 hr after birth. When the lamb was removed from the influence of the ewe for some hours after birth, the decline was retarded only if the lamb was held under conditions of minimal stimulation. After the udder was uncovered at 6?24 hr after birth, fewer lambs sucked successfully than in control groups. When the udder was uncovered there was a temporary elevation of teat-seeking activity, suggesting that activity was enhanced by reward. Early reward was ineffective, or was counteracted by satiety, since the activity of lambs allowed access to the teats from birth was lower than in lambs prevented from sucking. It is suggested that the initial peak in teatseeking is not soley due to hunger, because the teat-seeking activity was not completely suppressed by giving 600 ml of milk during the first 6 hr of life, and because the activity declined with fasting, when hunger should be increasing. |
