【摘要】：本试验旨在探讨王不留行黄酮苷和葛根异黄酮对哺乳母猪泌乳性能及血清激素和抗氧化指标的影响。试验采用2×2双因子随机设计,主效应分别为王不留行黄酮苷(0、2 g/kg)、葛根异黄酮(0、2.5 g/kg)及二者互作。选择胎次和预产期相近的经产长白母猪24头,随机分为4个组(对照组、王不留行黄酮苷组、葛根异黄酮组和混合组),每组6头猪。预试期7 d,正试期21 d。结果表明:1)混合组母猪平均日采食量显著高于对照组(P0.05);与对照组相比,各添加组哺乳第2周仔猪平均日增重均有升高的趋势,混合组显著高于对照组(P0.05)。各添加组常乳中胰岛素样生长因子I含量显著高于对照组(P0.05),且各组间均差异显著(P0.05)。2)混合组第1、10、21天血清中生长激素,第21天雌激素和第1、10、21天催乳素含量均显著高于对照组(P0.05)。3)各添加组第10、21天血清中谷胱甘肽过氧化物酶活性显著高于对照组(P0.05),第10、21天血清中丙二醛含量显著低于对照组(P0.05)。混合组第1、10、21天的血清中总超氧化物歧化酶活性显著高于对照组(P0.05)。综上所述,在本试验条件下,添加王不留行黄酮苷和葛根异黄酮提高了母猪的泌乳量,血清中催乳素、生长激素含量及总超氧化物歧化酶活性,使母猪泌乳性能、血清激素和抗氧化指标得到提高。
[Abstract]:The purpose of this experiment was to investigate the effects of flavonoid glycoside and kudzu isoflavones on lactation performance and serum hormone and antioxidant indexes in lactating sows. A 2 脳 2 two-factor randomized design was conducted. The main effects were as follows: flavonoid glycoside (0, 2 g/kg), isoflavones (0, 2.5 g/kg) and their interaction. 24 Landrace sows were randomly divided into 4 groups: control group (control group), kudzu isoflavones group (n = 6) and mixed group (n = 6), which were randomly divided into 4 groups (control group, kudzu isoflavone group and mixed group), which were divided into 4 groups: control group, kudzu isoflavone group and mixed group. The pre-trial period is 7 days, and the trial period is 21 d. The results showed that: 1) the average daily intake of sows in mixed group was significantly higher than that in control group (P0.05); Compared with the control group, the average daily gain of piglets in the mixed group was significantly higher than that in the control group (P0.05). The content of insulin-like growth factor I in the normal milk of each additive group was significantly higher than that of the control group (P0.05), and there was significant difference among the three groups (P0.05). 2) the serum growth hormone of the mixed group on the 1st, 10th and 21st day. The contents of estrogen and prolactin on day 21 were significantly higher than those in control group (P0.05). 3) the activities of glutathione peroxidase (GSH-PX) in serum at day 10 and 21 were significantly higher than those in control group (P0.05). The content of MDA in serum on day 10 and 21 was significantly lower than that in control group (P0.05). The activity of total superoxide dismutase in serum of the mixed group was significantly higher than that of the control group on the 1st, 10th and 21st day (P0.05). In conclusion, under the condition of this experiment, the content of prolactin and growth hormone in serum and the activity of total superoxide dismutase (SOD) were increased by adding flavonoid glycoside and puerarin isoflavones in sows, and the lactating performance of sows was improved by adding flavonoid glycoside and kudzu isoflavones. Serum hormone and antioxidant index were improved.
