【摘要】：本試驗(yàn)旨在探討王不留行黃酮苷和葛根異黃酮對(duì)哺乳母豬泌乳性能及血清激素和抗氧化指標(biāo)的影響。試驗(yàn)采用2×2雙因子隨機(jī)設(shè)計(jì),主效應(yīng)分別為王不留行黃酮苷(0、2 g/kg)、葛根異黃酮(0、2.5 g/kg)及二者互作。選擇胎次和預(yù)產(chǎn)期相近的經(jīng)產(chǎn)長(zhǎng)白母豬24頭,隨機(jī)分為4個(gè)組(對(duì)照組、王不留行黃酮苷組、葛根異黃酮組和混合組),每組6頭豬。預(yù)試期7 d,正試期21 d。結(jié)果表明:1)混合組母豬平均日采食量顯著高于對(duì)照組(P0.05);與對(duì)照組相比,各添加組哺乳第2周仔豬平均日增重均有升高的趨勢(shì),混合組顯著高于對(duì)照組(P0.05)。各添加組常乳中胰島素樣生長(zhǎng)因子I含量顯著高于對(duì)照組(P0.05),且各組間均差異顯著(P0.05)。2)混合組第1、10、21天血清中生長(zhǎng)激素,第21天雌激素和第1、10、21天催乳素含量均顯著高于對(duì)照組(P0.05)。3)各添加組第10、21天血清中谷胱甘肽過氧化物酶活性顯著高于對(duì)照組(P0.05),第10、21天血清中丙二醛含量顯著低于對(duì)照組(P0.05)�；旌辖M第1、10、21天的血清中總超氧化物歧化酶活性顯著高于對(duì)照組(P0.05)。綜上所述,在本試驗(yàn)條件下,添加王不留行黃酮苷和葛根異黃酮提高了母豬的泌乳量,血清中催乳素、生長(zhǎng)激素含量及總超氧化物歧化酶活性,使母豬泌乳性能、血清激素和抗氧化指標(biāo)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.
