【摘要】：為研究“吉姆瑞”系列產(chǎn)品對不同階段的生產(chǎn)母豬繁殖性能、仔豬健康狀況、仔豬生長性能、健康狀況和母豬激素含量變化、初乳生化指標(biāo)的影響,并為提升規(guī)�；i場的養(yǎng)殖效益提供客觀科學(xué)依據(jù)。本研究同步開展三個試驗(yàn):試驗(yàn)一:選擇達(dá)到7.5月齡、體重約115kg且體況相近的不發(fā)情或發(fā)情異常的大白后備母豬40頭,隨機(jī)將其分成2組,每組20頭,對照組飼喂基礎(chǔ)日糧,試驗(yàn)組是在基礎(chǔ)日糧中每天每頭添加一劑“吉姆瑞1號”,連續(xù)拌料飼喂1周,跟蹤測定兩組后備母豬的配種性能以及后續(xù)初產(chǎn)母豬的繁殖性能。試驗(yàn)二:選擇2~3胎次、體重、體況相近的斷奶后不發(fā)情或?qū)遗洳辉械慕?jīng)產(chǎn)大白母豬60頭,隨機(jī)分成吉姆瑞2號組、PG600激素組,每組30頭,對照組選擇胎次、體重、體況相近的正常經(jīng)產(chǎn)母豬30頭,對照組飼喂基礎(chǔ)飼糧,吉姆瑞2號組每天每頭添加1劑“吉姆瑞2號”,連續(xù)拌料飼喂1周;PG600激素組于試驗(yàn)開始的第1天每頭母豬注射1劑PG600,跟蹤測定各組經(jīng)產(chǎn)母豬的配種性能以及后續(xù)繁殖性能。試驗(yàn)三:選擇4~5胎次、體形體況相近、以往生產(chǎn)記錄基本一致的正常經(jīng)產(chǎn)大白母豬60頭,隨機(jī)分成試驗(yàn)組和對照組,每組30頭。2組采用相同的基礎(chǔ)日糧,試驗(yàn)組母豬配種期連續(xù)7天添加“吉姆瑞2號”,妊娠期連續(xù)添加“吉姆瑞3號”,泌乳期連續(xù)添加“吉姆瑞4號”,跟蹤測定兩組母豬的繁殖性能及其血液激素和初乳成分的變化。研究結(jié)果表明:試驗(yàn)一:1、后備母豬發(fā)情配種性能方面:試驗(yàn)組在7天內(nèi)和14天內(nèi)發(fā)情率分別比對照組高11.60和28.33個百分點(diǎn),返情率比對照組低16.67個百分點(diǎn),受胎率比對照組高21.60個百分點(diǎn)(P0.05)。2、后續(xù)初產(chǎn)母豬繁殖性能方面:試驗(yàn)組與對照組相比,在總產(chǎn)仔數(shù)、活產(chǎn)仔數(shù)、產(chǎn)弱仔數(shù)、出生窩重、21日齡斷乳窩重和成活率、28日齡轉(zhuǎn)群窩重和成活率等繁殖性能均無顯著差異(P0.05)。試驗(yàn)二:3、異常經(jīng)產(chǎn)母豬發(fā)情配種性能方面,吉姆瑞2號組在7 d內(nèi)發(fā)情率比PG600組低53.34個百分點(diǎn)(P0.05),14 d內(nèi)發(fā)情率、返情率以及總受胎率分別低20.00、8.21和10.00個百分點(diǎn)(P0.05),吉姆瑞2號組、PG600激素組母豬的受胎率均不如正常經(jīng)產(chǎn)母豬對照組(P0.05);4、后續(xù)繁殖性能方面,吉姆瑞2號組母豬窩均產(chǎn)活仔數(shù)、初生窩重、21日齡斷奶和28日齡轉(zhuǎn)群窩重及成活率均略高于PG600組,但3組母豬的后續(xù)各項(xiàng)繁殖性狀均無顯著差異(P0.05)。試驗(yàn)三:試驗(yàn)組母豬在14 d內(nèi)發(fā)情率和總受胎率比對照組分別提高9.43和9.31個百分點(diǎn)(P0.05);試驗(yàn)組母豬的后續(xù)繁殖性能也有不同程度的提高,尤其是21日齡窩重(泌乳力)和28日齡窩重分別比對照組提高了17.59%和19.26%(P0.05);試驗(yàn)組哺乳仔豬的腹瀉指數(shù)下降了18.18%(P0.05),皮毛發(fā)育狀況評分提高了5.44%(P0.05)。研究表明:試驗(yàn)?zāi)肛i配種期飼喂“吉姆瑞”后的6~12 h血清雌激素水平顯著提高、孕酮水平顯著降低(P0.05);泌乳母豬初乳中的乳脂和蛋白質(zhì)含量分別提高了57.47%和16.48%(P0.05)。試驗(yàn)表明:“吉姆瑞”對于治療發(fā)情異常的后備母豬、經(jīng)產(chǎn)母豬效果明顯,對于正常經(jīng)產(chǎn)母豬的生殖保健方面,可有效預(yù)防高胎次母豬出現(xiàn)發(fā)情障礙的出現(xiàn),提高母豬繁殖性能、再繁殖性能、改善母豬泌乳力、仔豬的日增重及健康狀況,改善豬群健康。
[Abstract]:In order to study "Jimurui" series of products on reproductive performance in different stages of the production of sows, piglets growth performance, health status, health status and changes of hormone content of sows, effect of colostrum and biochemical indicators, and provide scientific basis for the objective to enhance the scale of pig breeding efficiency. The three test carried out simultaneously in this study: test one: select at 7.5 months old, weighing about 115KG and the similar body condition not estrus or abnormal estrus in large white gilts and 40 heads, and were randomly divided into 2 groups, 20 pigs in each group, the control group was fed basal diet, the test group is every day in the basic diet added per head a "Jimurui No. 1". Continuous mixing feeding for 1 weeks following mating performance were measured in two groups of gilts and subsequent reproductive performance of primiparous sows. Experiment two: 2~3 parity, body weight, body condition similar to postweaning estrus or not sterility in Large White Sows 6 0 pigs were randomly divided into 2 groups Jimurui, PG600 hormone group, 30 pigs in each group, the control group selection of parity, body weight, body condition is similar to the normal sows 30, the control group was fed a basal diet, Jimurui No. 2 group every day, adding 1 head agent "Jimurui No. 2", continuous mixing feeding for 1 weeks; first days to start the PG600 hormone group test per sow 1 doses of PG600, tracking the breeding performance was measured and the subsequent reproductive performance of multiparous sows. Experiment three: 4~5 parity, body body condition is similar to that of normal multiparous Large White Sows production records consistent 60, were randomly divided into experimental group and control group. Each of the 30 head group.2 with the same basal diet, test group sows breeding period for 7 consecutive days to add "Jimurui No. 2", add "Jimurui consecutive pregnancy lactation No. 3", add "Jimurui No. 4" continuous tracking, reproduction and performance test of two groups of female pigs Changes of serum hormone and colostrum composition. The results show that: the test: 1, sow oestrus performance: in the experimental group, 7 days and 14 days respectively, the oestrus rate higher than the control group 11.60 and 28.33 percentage points, return rate of 16.67 percentage points lower than the control group, the pregnancy rate is higher than the control group 21.60 percentage points (P0.05).2, the subsequent reproductive performance of gilts: compared to the experimental group and the control group, the total number of piglets born alive litter size, birth weak litters, litter birth weight, 21 day old weaned litter weight and survival rate of 28 days of age to group litter weight and survival rate were not significant the difference of breeding performance (P0.05). Experiment two: 3, abnormal sows estrus performance, Jimurui No. 2 group within 7 d estrus rate was 53.34 percentage points lower than the PG600 group (P0.05), 14 d in the oestrus rate, return rate and total fertility rate were low (P0.05 20.00,8.21 and 10 percentage points Jimurui), No. 2 group, PG6 00 hormone group sows conception rate of sows were as normal control group (P0.05); 4, the subsequent reproductive performance of sows, Jimurui No. 2, the number of live births, birth weight, weaning at 21 days and 28 days of age group to litter weight and survival rate were slightly higher than the PG600 group, but breeding the following 3 traits group sows showed no significant difference (P0.05). Experiment three: test group sows estrus rate within 14 d and the total pregnancy rate than the control group were increased by 9.43 and 9.31 percentage points (P0.05); the subsequent reproductive performance of sows in experimental group have different degrees of increase, especially at the age of 21 days litter weight (lactation) and litter weight at 28 days respectively than the control group increased by 17.59% and 19.26% (P0.05); diarrhea index of piglets in experimental group decreased by 18.18% (P0.05), the score increased 5.44% fur growth (P0.05). The study shows that the breeding sows fed Jimurui test period after 6~12 serum H Estrogen levels increased significantly, progesterone levels were significantly lower (P0.05); milk fat and protein content in colostrum of lactating sows were increased by 57.47% and 16.48% (P0.05). Experiments show that: "Jimurui" for the treatment of abnormal estrus in gilts and sows significantly, for reproductive health care of normal sows, can effectively prevent the high there appeared disorder parity sow estrus, improve the reproductive performance of sows, and then improve the reproductive performance of lactating sows, piglets, weight gain and health status, improve herd health.
