Growth data and feed intakes were recorded from 333 male, Friesian calves from birth to 11 weeks of age. The calves came from seven experiments. All calves were weaned from milk replacer at five weeks and fed a starter from two to eleven weeks of age. The average birth weight of the calves was 42.6 kg, they gained 13.6 kg to weaning at five weeks and ...

Weaning Weight Response of Pigs to Simple and Complex Diets
Journal of Animal Science, 1985Five experiments were conducted to determine (1) the value of simple vs complex diets on gains and feed conversion of pigs weaned at a constant age but varying in weight, (2) the optimum postweaning time to change from a complex to a simple diet and (3) the effect of previous treatment on subsequent performance.

The performance of early-weaned piglets following transport: Effect of season and weaning weight
Canadian Journal of Animal Science, 2006Two groups of 48 Cotswold piglets weaned at 17 ± 1 d of age were assigned to road or simulated transport during summer or winter. Following transport [Control (<20 min), 6 h, 12 h or 24 h], piglets were grouped by weaning weight (light, medium and heavy) in pens of four. Body weights were recorded on days 1–8, 10, 12 and 14. From an average weaning

Factors associated with average pig weight at weaning on farms using early weaning
Animal Science, 1998AbstractThe objective of this study was to investigate the effect of various factors on average pig weight at weaning on farms using early weaning. Farms were selected based on average weaning age and whether they recorded lactation food intake and litter weights at weaning.

Effects of weaning and weaning weight on neuroendocrine regulators of feed intake in pigs.
Journal of animal science, 2007A depression in feed intake and growth often occurs in the weaned pig. Spray-dried plasma is often added to nursery diets in an attempt to stimulate feed intake during this lag. The current study evaluated gene expression of appetite regulators in hypothalamus and adipose tissue 4 d after weaning. Barrows (2 wk of age) were cross-fostered to a sow (SOW,

The behaviour of early-weaned piglets following transport: Effect of season and weaning weight
Canadian Journal of Animal Science, 2008Two groups of 48 Cotswold piglets were weaned at 17 ± 1 d of age and assigned to road or simulated transport during summer or winter. Following transport (0, 6, 12 or 24 h), piglets were grouped by weaning weight (light, medium and heavy) in pens of four. Piglet behaviour was recorded on days 1–4, 7 and 14 after weaning and transport.

Sire × herd interactions for weaning weight in beef cattle
Journal of Animal Science, 1992Weaning weight records of 44,357 Australian Angus calves produced by 1,020 sires in 90 herds were used to evaluate the importance of sire x herd interactions. Models fitted fixed effects of contemporary group (herd-year-date of weighing subclass), sex, calf age, and dam age and random effects of sire or of sire and sire x herd interaction using REML ...

HERITABILITIES OF WEANING WEIGHT, YEARLING WEIGHT, AND CLEAN FLEECE WEIGHT IN RANGE ROMNELET SHEEP
Canadian Journal of Animal Science, 1961Heritabilities of weaning weight, yearling weight and clean fleece weight for range Romnelet sheep were estimated by the intra-sire regression of daughter on dam from data adjusted for year effects, age of dam, type of birth and rearing and age of lamb or yearling ewe.

This study investigated the effect of litter size and parity on birth weight, weaning weight and survival at weaning and also, the effect of variations of birth weight on number and weight of piglets weaned and on pre-weaning survival. This experiment was performed on 114 sows and their 851 piglets.
