Variation In Piglet Weights: Weight Gains In The First Days After Birth And Their Relationship With Later Performance, B. K. Thompson, D. Fraser
Variation In Piglet Weights: Weight Gains In The First Days After Birth And Their Relationship With Later Performance, B. K. Thompson, D. Fraser
Ontogeny Collection
Piglets from 42 litters of Yorkshire sows were weighed 0, 1, 2, 3, 4, 5, 7, 10, and 14 d after farrowing in order to explore the highly variable weight gains during the first 2 wk after birth. All litters were adjusted to 10-12 piglets by fostering. Litters differed greatly in average gain per piglet during the first 3 d after farrowing, with litter means ranging from 5 to 227 g d‒1 per piglet for the 3-d period. Gains during days 0-3 tended to be somewhat lower if the sow had a high body temperature during these days, but the …

Use of drinking water was determined for 51 litters of piglets by weighing and refilling a water dispenser each day for the first 4 d after farrowing. Measures of spillage, evaporation, and piglet drinking behavior indicated that most disappearance of water represented actual drinking by the piglets. Water use varied greatly among litters with an average of 46 g d‒1 per piglet over the 4 d, and a range of negligible use to about 200 g d‒1. Water use, especially on day 2, was correlated negatively with the average weight gain of the litter during the first …
