Relationship between energy intake, backfat thickness and reproductive performance of sowsTrottier, Nathalie Lucie January 1990 (has links)
Three experiments were conducted on sows. In experiment I, Landrace gilts were fed ad libitum, from 10 weeks of age to puberty, diets containing either 2800 (LE), 3400 (ME) and 3900 (HE) Kcal DE/kg. Age at puberty was delayed in gilts fed LE and ME. Backfat thickness was significantly reduced in LE and ME groups. Puberty onset was more determined by age and backfat thickness than by weight. In experiment II, all gilts that had shown normal heat within 240 days of age, were inseminated on the second estrus and given the same diet as received during their growing period. Feed was restricted to 2.0 kg per day during gestation and was provided ad libitum in lactation. Gilts in LE and ME gained less weight and backfat during gestation than gilts in HE group. Gilts gaining more weight and backfat during gestation, with a resulting higher body weight and backfat thickness at parturition, lost more in lactation. Incidence of anoestrus after weaning was higher in the LE and HE groups. In experiment III, multiparous Landrace-Yorkshire sows from two herds were used. An extended weaning to remating interval and reduced number of piglets weaned was observed in first and second parity sows. Lower reproductive performance in one herd was related to an excessive loss of backfat in lactation and a low backfat level at weaning.

Effects of feeding flaxseed to sows during late gestation on lactation and litter performanceOresanya, Temitope Frederick. January 2000 (has links)
A study was conducted to investigate the effect of supplemental fat from flaxseed (FL) on fatty acid (FA) profile, chemical composition, energy value of colostrum and milk, and litter performance. On day 107 of gestation a total of 59 large white sows were selected, blocked by parity and randomly allotted to one of three diets, 15% flaxseed (FL), 10% fullfat soybean (SB) or a control commercial (CO) diet containing corn and soybean meal. Diets were isocaloric and isonitrogenous but differed in fat content and FA composition. Colostrum and milk were collected soon after farrowing and on day 7, respectively, for fatty acid and chemical analysis. Dietary treatments did not affect sow feed consumption, weight loss, number of live pig born and weaned per litter. Similarly, pig birth weights, and day 7, 14, and 21 weights did not differ among treatment groups. FL significantly (p < 0.05) increased linolenic (LNA C18:3co3) and decreased palmitic (C16:0) and oleic (C18:1) acids in colostrum. FL also significantly (p < 0.001) increased LNA and arachidonic acid (C20:4) in milk, while it decreased myristic (C14:0), palmitic and palmitoleic (C16:1) acids. Chemical analysis showed no significant differences in total solids (TS) and energy value of colostrum while a significant (p < 0.05) increase in TS, fat concentration and energy value was observed in milk from FL. A total of 335 piglets were used in the plasma study of lipid metabolites. Triglyceride (TG), cholesterol, HDL cholesterol and glucose were not affected by dietary treatment (p > 0.05). Feeding FL to sows during late gestation and lactation enriches sow milk and piglets with LNA.
