Whole Cottonseed

Eight multiparous Holstein cows in mid lactation (average days in milking of 160 ± 40) were used in a replicated 4 by 4 Latin square design, each experimental period lasting 3 weeks, to determine the effects of whole cottonseed (WCS) treatment and dietary crude protein (CP) concentration on the profile of milk fatty acids. Each 3-week experimental period consisted of 2 weeks for ration adaptation followed by 1 week for data collection. The experimental diets consisted of: (1) Control (without WCS), 16% CP; (2) 20% WCS, 16% CP; (3) 20% WCS, 13% CP; and (4) 20% crushed WCS, 13% CP. Minerals and vitamin supplements were the same in all experimental diets. The WCS treatment led to increased DM intake, fat-corrected milk yield, fat concentration, proportion of long-chain fatty acids, unsaturated fatty acids and ratio of unsaturated to saturated fatty acids (P < 0.05). Decreased concentration of dietary CP from 16 to 13% (diet 2 compared with diet 3) led to a decrease in both milk yield and milk composition (P < 0.05). WCS crushed in diets with 13% CP (diet 4 compared with diet 3) increased (P < 0.05) the concentration of conjugated linoleic acid in milk fat. The results demonstrated that adding WCS to the diet of lactating cows improves both milk yield and milk fatty acid profile, particularly the proportion of conjugated linoleic acid.

Suckling Piglets

This experiment was conducted to evaluate the effects of dietary conjugated linoleic acid (CLA) supplementation during late gestation on reproductive performance, colostrum yield, colostral fatty acid composition, and immunoglobulin G (IgG) concentrations in primiparous sows. Twenty-four primiparous Landrace × Large White pregnant sows were randomly selected and assigned to four dietary treatments: 0% (control), 0.75%, 1.50%, and 2.25% CLA supplementation from day 85 of gestation to parturition. During lactation, all sows were fed the same commercial diet. The preweaning mortality of suckling piglets born to dams fed supplemental CLA did decrease linearly (P = 0.01) during lactation. Administration of CLA during gestation increased linearly (P < 0.01) total saturated fatty acids and decreased linearly (P < 0.01) monounsaturated fatty acids and polyunsaturated fatty acids in colostrum. The concentrations of CLA isomers were higher (P < 0.01) in colostrum from primiparous sows fed CLA diets than in the control group. Feeding CLA increased (P < 0.05) colostral IgG concentrations, as well as that in the serum of neonatal piglets. In conclusion, 2.25% CLA supplementation in the diet of primiparous sows during late gestation could improve the passive immunity through colostral IgG and the survival of suckling piglets.
