“…Increases in colostrum and milk fat due to dietary lipid addition have been reported previously (Seerley et al, 1974(Seerley et al, , 1978aFriend, 1974;Cast et al, 1977;Boyd et al, 1978). Seerley et al (1978b) reported that increased fat content of colostrum was associated with increased energy density but observed no difference in protein content compared to a control group which was fed isocalorically.…”

“…A similar observation has been reported (Okai ct al., 1977) for pigs whose dams were fed a 10% tallow diet ad libiturn during late gestation. In previous experiments in which 15 or 20% tallow diets were fed through a 14-d lactation period (Cast et al, 1977;Boyd et al, 1978), pig weights appeared to be similar to those in a control group.…”

“…Seerley et al (1978b) reported that increased fat content of colostrum was associated with increased energy density but observed no difference in protein content compared to a control group which was fed isocalorically. Greater fat content and thus energy density is important to smaller, less competitive pigs which nurse less frequently than larger pigs (Hartsock and Graves, 1976;Boyd et al, 1978) since the initial 12 to 24 h is a period of critical energy status (i.e., glucose).…”

SummaryFour trials were conducted with a total of 188 crossbred sows to determine the effect of feeding diets supplemented with tallow (0 or 8%) and choline chloride (220 or 770 mg/kg diet) prior to parturition and during lactation on preweaning pig performance. On d 100 of gestation, sows were allotted to four factorially arranged dietary treatments: 0% tallow-220 mg/kg choline chloride, 0% tallow-770 mg/kg choline chloride, 8% tallow-220 mg/kg choline chloride, 8% tallow-770 mg/kg choline chloride. Diets without tallow were fed at the rate of 1.82 kg/d with an additional .18 kg/d of cornstarch, whereas sows receiving diets supplemented with tallow were fed 1.82 kg/d. Daily metabolizable energy intake was constant for all diets (approximately 6,240 kcal). Following parturition, the diets were fed ad libiturn for a 21-d lactation period. Pig survival to 21 d, in relation to the number of pigs born alive/litter, did not differ significantly between litters from sows receiving tallow (94.0%) and litters from sows receiving the control diet (92.5%). Although not significantly different, there was a trend toward slightly heavier pigs (6.35 vs 6.11 kg) and litters (53.97 vs 51.94 kg) after the 21-d lactation period in the groups nursing sows receiving tallow-supplemented diets. Litter performance was not improved by

“…Seerley et al (1974) observed that addition of corn oil to the diet from gestation day 109 through lactation increased survival rate of the pigs weighing less than 1,000 g at birth. Boyd et al (1978), who introduced a 20% tallow lactation diet on gestation day 100, observed a slight increase in survival rate and an increase in fat content of colostrum. In another study, Boyd et al (1979) found that adding 8% tallow to the sow's diet increased both total solids and fat content of the milk.…”

SummaryEighty-eight crossbred sows were used to evaluate the effects of including sun-cured alfalfa in gestation diets and tallow in lactation diets on reproductive performance for three successive reproductive cycles. Two pelleted gestation diets were fed: (1) no alfalfa and (2) 50% alfalfa. Both diets were fed at the rate of 6,000 kcal of ME/head/day for the first 90 days of gestation. Two lactation diets were fed, one containing no added tallow and the other 8% stabilized tallow. Lactation diets were initiated at approximately 90 days of gestation and fed at a rate of 2.72 kg/head/day until farrowing and offered ad libitum postpartum. A higher percentage of the sows fed the alfalfa treatment completed the three gestation-lactation cycles than did those fed the control diet. Although total pigs farrowed per litter did not differ significantly between treatments, a reduction (P<.05) in average birth weight was observed for the alfalfa-fed group. The number of pigs alive at 14 days was higher for the alfalfa-fed group (P<.05). Survival rate pooled over the three reproductive cycles was approximately 8% higher for sows fed alfalfa; the addition of tallow did not significantly improve survival rate. Sows fed alfalfa diets gained less (P<.05) during gestation than controls, but lactation diets did not affect maternal weight gains. Sows fed the tallow lactation diet consumed 6.8% less feed than the controls (P<.05), but total energy intake for both diets was similar.
