Abstract

This experiment was conducted to study the effects of different supplemental levels of extruded alfalfa meal-linseed during late-gestation and lactation period on reproduction performance and fatty acid composition in colostrum of sows. In this trial, eighty Landrace×Large White primiparous sows in later gestation (83 days of gestation) were randomly allotted to 4 groups with 4 replicates in each group and 5 sows in each replicate. Sows in the control group were fed a basal diet, and those in experimental groups were fed the basal diet supplemented with 5%, 10% and 15% extruded alfalfa meal-linseed, respectively. The trial lasted for 55 days after 7 days adaption. The results showed as follows:1) compared with the control group, dietary extruded alfalfa meal-linseed significantly increased average daily feed intake of sows (P<0.05), which in 15% extruded alfalfa meal-linseed supplemental group was the highest. 2) With the extruded alfalfa meal-linseed supplemental level increasing, the backfat thickness loss of sows in lactation was decreased, while the litter weight of day 21, average litter daily weight gain, individual weight of day 21 of piglets as well as the monounsaturated fatty acid (MUFA) and the ratio of unsaturated fatty acid to saturated fatty acid (UFA/SFA) in sow colostrum were increased with no significant differences (P>0.05). 3) When piglets weaning (21 days of age), the best weight distribution in 15% extruded alfalfa meal-linseed supplemental group was the best. It is concluded that extruded alfalfa meal-linseed can enhance the reproduction performance of sows, and increase the MUFA content and UFA/SFA ratio in sow colostrum.
