摘要

目的:评估补充亚麻籽对母猪代谢状况、内分泌浓度、非酯化脂肪酸(NEFA)、身体成分变量和繁殖性能的影响。方法:从本次分娩第1天开始,当开始饲喂特定补充日粮直到随后分娩的那一天(第150至155天)时,将21头大白约克郡杂交母猪全部纳入研究期,并将其平均分为三组。第1组作为对照组,并遵循其正常喂养计划。第2组和第3组,除了正常的喂养计划外,还分别以干物质的0.5%和1.0%的比例补充亚麻籽。在分娩前15天、分娩当天(第0天)、哺乳期第28天之前每周采集血样,妊娠期间每月采集血样以采集血浆。血浆用于评估母猪的代谢和内分泌状况。测量每头母猪的体重和所有出生仔猪的个体出生体重。结果:与对照组相比,添加亚麻籽组的血浆胆固醇和甘油三酯水平降低(P0.05)。结论:亚麻籽改善了内分泌状况、NEFA浓度和体重,从而提高了妊娠率和产仔数。

Effect of flaxseed supplementation on metabolic state, endocrine profiles, body composition and reproductive performance of sows
Objective: To assess the effect of flaxseed supplementation on metabolic profile, endocrine concentrations, non-esterified fatty acids (NEFA), body composition variables, and reproductive performance of sows. Methods: All the 21 crossbred Large White Yorkshire sows were considered in the study period starting at day 1 of current farrowing when the feeding of specific supplemental ration was started until the day of subsequent farrowing (days 150-155) and were equally allocated into three groups. Group 1 served as the control group and followed their normal feeding schedule. Group 2 and group 3, in addition to their normal feeding schedule, were supplemented with flaxseed at a rate of 0.5% and 1.0% of the dry matter, respectively. Blood samples were collected 15 days prior to farrowing, on the day of farrowing (day 0), at weekly intervals until day 28 of lactation and at monthly intervals during gestation to harvest the plasma. Plasma was used to assess the metabolic and endocrine status of sows. Body weight of each sow and individual birth weight of all piglets born were measured. Results: Flaxseed supplementation led to decrease in plasma cholesterol and triglyceride levels in the supplemented groups than in the control group (P<0.05). Plasma estradiol-17β level was higher in group 2 than that in group 1 and 3 on day 90 of the gestation period (P<0.05). The mean plasma level of insulin-like growth factor 1 was higher in group 3 than that in group 1 and 2 both in late lactation (day 28) as well as in early gestation (day 30) (P<0.05). Plasma NEFA and weight gain were greater in sows of group 2 and 3 compared to those fed with the normal control diets (P<0.05). The proportion of pregnant sows relative to sows bred was 100.0% in group 2 and 3 and 85.7% in the control group. Piglet mortality was lower in group 2 and 3 compared to group 1 (P>0.05). Conclusions: Flaxseed improves endocrine profiles, NEFA concentrations and body weight, resulting in better pregnancy rate and litter size.
