“…However, by the end of lactation milk yield tended to be higher in E G2, P G2 and F G2 mothers, and is in agreement with the findings of others (Boyd et al, 1982;Noblet and Etienne, 1986;Shurson et al, 1986). Supplementation of sow diets with fat during late pregnancy and lactation has been demonstrated to increase the concentration of fat in colostrum and milk (Boyd et al, 1982;Coffey et al, 1982). However, we failed to show any differences in percentage milk fat, or indeed protein and lactose with respect to diet but those animals supplemented during G2 tended to have higher percentages of fat and protein in their milk; this was only true for the first week of lactation.…”

“…Coffey et al (1982) reported that fat supplementation of sows during late gestation resulted in increased milk yields. Other studies suggest that an increased plane of nutrition during late gestation may have a negative effect on sow performance during lactation.…”

“…It is likely that the transfer of fatty acids across the placenta will be affected by the fatty acid profile of the maternal diet, which in turn will influence foetal development. Furthermore, neonatal development is also likely to be affected due to changes in milk fatty acid composition as a result of altering the maternal diet during late gestation (Seerley et al, 1974;Coffey et al, 1982;Wladyslaw, 1991) The role of the fatty acid profile of dietary fat supplements during mid-late gestation, in sows, has not yet been fully established. Using oil supplements with different fatty acid profiles, this study aimed to determine the consequences of altering the fatty acid composition of sow diets during the second half of gestation; consideration was given to farrowing performance, neonatal outcome, and the growth and development of offspring up until commercial end point (E140 days).…”

This study aimed to determine the consequences of altering the fatty acid profile of sow diets during mid-to-late gestation; oils of different fatty acid composition were chosen as energy supplements to provide diets with different fatty acid profiles. Forty-eight multiparous sows were used to evaluate the effects of fat supplementation from day 60 of gestation until parturition. Sows were allocated to either 3 kg/day of commercial sow pellets (control; C) or an experimental diet consisting of 3 kg/day of commercial sow pellets supplemented with 10% extra energy in the form of excess pellets (E), palm oil (P), olive oil (O), sunflower oil (S) or fish oil (F). From days 0 to 60 of gestation, all sows were given 3 kg/day of sow pellets as for the C group. The E diet resulted in the heaviest piglets at birth whereas the offspring of O and S sows were the lightest at birth. The offspring of S sows remained lighter throughout the pre-weaning period, and were also the leanest by 14 days of age. In contrast, pigs born to S sows possessed more fat by the time they reached commercial end point (E140 days of age). In conclusion, altering the fatty acid profile of the sow diet during the second half of gestation has long-term consequences for the development of their offspring.

“…During the sucking period, the piglet undergoes such rapid growth that Berge and Indrebo (1953) As shown by Friend (1974) (Friend 1974;Boyd et al 1978b;Coffey et al 1982 For personal use only.…”

At birth, piglets have little body fat that can be mobilized. The influx of high-fat milk causes a rapid increase in body fat stores and a depression of lipogenic enzyme activity. Conversely, lipolytic enzyme activity increases after birth. Changing the fat intake of sucking piglets affects the amount of fat deposition. The length of the sucking period also influences body composition at weaning. Weaning produces a pronounced but temporary decrease in total body lipid, despite an increase in fat synthesis. The effect of weaning on lipolysis is not clear due to a lack of experimental data. During the growing period, fat continues to build up even though lipogenic enzyme activity tends to decline with age. The composition of the diet, the sex of the animal and genetic factors have all been shown to influence the rate of lipogenesis. Fewer reports have been published in which factors affecting lipolysis have been studied and the results are often less conclusive. However, the combined activities of lipogenic and lipolytic processes do not account for the large quantity of body fat found in growing pigs. Key words: Swine, fat, lipogenesis, lipolysis, diet, sex.
