【摘要】：本試驗(yàn)旨在研究飼糧能量水平對(duì)后備母豬卵巢發(fā)育及卵巢促卵泡素受體(FSHR)和促黃體素受體(LH/CGR)mRNA表達(dá)的影響。選擇27頭體重(61.0±3.1)kg的長(zhǎng)×大二元母豬,隨機(jī)分成3組(每組3個(gè)重復(fù),每個(gè)重復(fù)3頭豬),分別飼喂低、中、高3個(gè)能量水平[分別為NRC(1998)推薦消化能需要的90%、100%和110%]的飼糧。試驗(yàn)期內(nèi)各組平均日采食量相同,但攝入的消化能水平不同。試驗(yàn)?zāi)肛i在第2個(gè)發(fā)情期的第19天屠宰。結(jié)果表明:高能組卵巢重及大卵泡數(shù)顯著高于低能組(P0.05);各組間小卵泡數(shù)量差異不顯著(P0.05)。高能組卵巢FSHR和LH/CGR mRNA表達(dá)量最高,顯著高于低能組(P0.05)。由此得出,高能量水平飼糧可促進(jìn)后備母豬卵巢發(fā)育,有利于促進(jìn)卵巢FSHR和LH/CGR mRNA的表達(dá)。
[Abstract]:The purpose of this study was to study the effects of dietary energy levels on ovarian development and the expression of follicular hormone receptor (FSHR) and luteinizing hormone receptor (LH/CGR) mRNA in reserve sows. Twenty-seven long 脳 large binary sows weighing (61.0 鹵3.1) kg were randomly divided into three groups (3 repeats in each group, 3 pigs in each group) and fed with low, medium, respectively. High energy levels [90 per cent, 100 per cent and 110 per cent of recommended digestive energy requirements for NRC (1998), respectively]. During the experimental period, the average daily feed intake of each group was the same, but the level of digestive energy intake was different. The sows were slaughtered on the 19th day of the second estrus. The results showed that the ovarian weight and the number of large follicles in the high energy group were significantly higher than those in the low energy group (P 0.05), but there was no significant difference in the number of small follicles among the groups (P 0.05). The expression of FSHR and LH/CGR mRNA in high energy group was the highest, which was significantly higher than that in low energy group (P 0.05). It was concluded that high energy level diet could promote ovarian development and the expression of FSHR and LH/CGR mRNA in reserve sows.
