Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer
Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer
Feeding Behavior Collection
Individual daily consumption of supplementary solid food ('creep feed') was measured from Day 10 to weaning at Day 28 for 39 piglets in four litters, and its relationship to body weight and weight gain up to Day 42 was investigated. Individual consumption was measured by combining the weight of the feed removed from the dispensers (monitored electronically) and a video image of piglet activity at the feeder. Creep feed consumption varied greatly, both between and within litters. On average, pigs began feeding on Day 12 (range Day 10-28), intake was relatively low (usually < 5 g day ‒1) until Day 20 but increased …

Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen
Social Behavior Collection
The effects of straw on the behaviour of young growing pigs were studied in two experiments. In Experiment 1, group of three pigs, aged about 7 weeks, were housed in raised decks with or without straw bedding. Time-lapse video recording showed no major differences between treatments in the amount or daily pattern of overall activity and feeding. Detailed observations showed that bedding reduced the incidence of rooting and chewing on pen-mates, but had little effect on other social activities such as mounting and aggressive biting. Experiment 2 compared groups of eight growing pigs aged about 10 weeks, housed in floor …
