Gilts were assigned as controls (CTL, n = 6) or received orally 10 mg of bromocriptine thrice daily from d 110 of gestation until farrowing, (BRPP, n = 7), from d 1 to 6 postpartum (PP) (BRL1, n = 6), from d 7 to 13 PP (BRL2, n = 7), from d 14 to 20 PP (BRL3, n = 6), or from d 21 to 27 PP (BRL4, n = 6). Weights of pigs were recorded at birth, 24 h later,(More)
Forty-eight crossbred gilts were used in an experiment with a 2 x 2 x 2 factorial arrangement of treatments. Treatments were control or bulky diet during gestation (4.1 vs 15.3% crude fiber), number of meals served daily in lactation (2 vs 4), and three daily s.c. injections of saline or of 1 mg of a human growth hormone-releasing factor analog (GRF-AN)(More)
Extensive cross-fostering is widely used in early-weaning units in order to standardize and improve body weight at weaning. However, young suckling piglets develop teat fidelity and repeated cross-fosterings could go against this behavior. This experiment was therefore conducted to compare the behavior and growth of 13 control and 14 fostered litters. Once(More)
The aim of the present study was to determine the effect of different degrees of bulkiness in the gestation diet on reproductive performance of sows during their first two parities. The density of the diets was modified by incorporating a high proportion of fibrous ingredients (wheat bran and corn cobs in Diet 2 and oat hulls and oats in Diet 3). A diet(More)
Third-parity sows received s.c. injections of sterile water (CTL, n = 12) or 15 mg of recombinant porcine prolactin (pPRL, n = 12) at 0730, 1530, and 2330 from d 2 to 23 of lactation. Litters were standardized to 11 or 12 pigs and were weighed weekly until weaning (d 24). On d 22 of lactation, milk production was estimated, and a milk sample was obtained(More)
Segregated early weaning (SEW), introduced with the objectives of eradicating or controlling diseases and improving performance, is becoming increasingly popular among producers. The main features of SEW are weaning piglets early and moving the newly weaned piglets to a site isolated from the sows and other animals. In this article, we describe the key(More)
To investigate the role of peripheral prolactin in stimulating the preparturient activity of pigs, 12 cross-bred gilts housed in standard farrowing crates either received orally 10mg of bromocriptine three times per day from day 110 of gestation or served as controls. Jugular blood samples were collected on days 107 and 113 and assayed for prolactin, while(More)
In the first part of this paper, the authors discuss the growing concern of consumers for farm animal welfare, and the attitude adopted by veterinarians to cope with this new and more humanitarian concept of intensive husbandry. The effects of intensification of pig production on the ability of pigs to adapt, and the behavioural, husbandry and health(More)
Until recent years it has been generally assumed that intellectual development and decline ran a relatively smooth and predictable course. Childhood was a period of rapid, uniform intellectual growth followed by a period of slower development during adolescence and perhaps early adulthood. After reaching its peak in the late teens or early twenties a(More)
The effect of restricted feeding on the frequency of abnormal behaviors and gastric ulcers was investigated in 72 market pigs. Half of the pigs were fed restricted (R) amounts of feed twice a day (0800 and 1600) and received 90 to 95% of the intake recorded for the other half, which were allowed ad libitum (A) access to feed with addition of feed once a day(More)
