Adjustment factors for lamb weaning weight

New Zealand Journal of Agricultural Research, 1985
Abstract Nine methods of adjusting lamb weaning weight for the effects of age‐of‐dam, sex, birth‐rearing rank, and weaning age were compared. Evaluated several ways, the effectiveness of the methods did not differ very much. It is concluded that the best adjustment procedures are the combined additive and multiplicative, or ...

Direct and correlated responses to selection for weaning weight, post-weaning weight gain and six-week weight in mice

Theoretical and Applied Genetics, 1984
Four lines of mice were formed from a common base population and selected for 37 generations for either increased 3-week weight (weaning weight), 6-week weight, 3-6 week gain, or maintained as a randomly bred control line. Realised heritability estimates for short-term (long-term) responses were 0.33±0.20 (0.07±0.10), 0.46±0.14 (0.26±0.09), 0.36±0.14 ...

The relation of weaning weight to birth weight of lambs

Proceedings of the British Society of Animal Production, 1955
It is now a well established fact that high-level nutrition of the in-lamb ewe during the later stages of pregnancy results in heavy lambs of high vitality at birth and in good milking ewes. On the other hand, when ewes are poorly fed during the same period, or suffer a check, they produce underweight lambs of low vitality and have poor milk yields ...

The aim of this paper is to compare weight and weight gain in two groups of infants; one group weaned before 4 months (early weaned), the other weaned at 4 months or after.Methods  Feeding practices were assessed through semistructured ...
