| For the study of reproductive nutrients and herbal medicine in different stages of production and reproductive performance, health, growth performance, and hormone content changes affect sow colostrum biochemical indicators and to enhance swine production benefits provide an objective scientific basis. This study was carried out simultaneously three tests:Test1: Select weighing about 120 kg of 40 grew up Landrace-Yorkshire Hybrid Sowswere randomly divided into 2 groups. Control group was fed the basal diet, the experimental group added to the basic diet per head per day a "reproductive nutrients and herbal medicine-1", to the end of 21 days after estrus. Breeding pigs and the way the two groups follow a consistent method of feeding and management, tracking performance was measured two estrus gilts gilts and subsequent reproductive performance.Test 2: Select the previous breeding normal childbirth grew up Landrace-Yorkshire Hybrid 1 week 40 sows were randomly divided into 2 groups. After 1 week of pre-test, the control group was fed the basal diet, the experimental group added to the basic diet per head per day a "reproductive nutrients and herbal medicine-1," for feeding to 21 days after the end of estrus. Breeding pigs and the way the two groups follow a consistent method of feeding and management, tracking, measuring two sows estrus and subsequent reproductive performance.Test 3: Select normal pregnancy 3 parity Yorkshire sows 60, were randomly divided into three groups. Control group was fed the basal diet, the experimental group(1) within 7 days of prenatal test group(2) in prenatal 25 days began in the basal diet supplemented with a per head per day "reproductive nutrients and herbal medicine-2" until the end of weaning. Three groups of breeding pigs manner and subsequent feeding and management methods consistent track measuring three lactation lactation performance, growth and development of piglets and sows subsequent estrus conception rate.Research indicates:Test 1: the test group gilts improve in 7 days and 14 days respectively estrus rate than the control group, 7.63 and 6.31 percentage points, estrus rate decreased 21.43 percent, 22.11 percent increase conception rate(P <0.05). Subsequent reproductive performance of gilts have different degrees of increase, compared with the control group, the experimental group, the average total number born gilts improved 1.56(P <0.05), increase the number of pigs born alive 2.43(P <0.05), piglets born litter weight increase 28.95%(P <0.05), 21-day weaning weight increase a 6.74%(P <0.05), weaning litter weight increased 12.72%(P <0.05), weaning breeding rate 8.56 percentage points; gilts lactation increase 12.72%(P <0.05). Compared with the control group, the experimental group gilts preterm birth rate and stagnant yield decreased respectively 23.86 and 20 percentage points, lactation Triad reduce the incidence of 21.02 percent, weaning sow body condition score increased 23.11%( P <0.05); test group piglets diarrhea rate reduced 4.92 percentage points, weaned fur developmental score increased 18.37%(P <0.05)Test 2:(1) estrus: the experimental group compared with the control group, the rate of sows weaning estrus and conception rate within 14 d were increased by 10 percent(P <0.05).(2) the subsequent reproductive performance: compared with the control group, the experimental group of sows farrowing average total number of pigs born alive and were increased by 1.18 and 1.23, an average piglet birth weight and litter weight at birth increased by 10.29% and 26.00%, 21-day weaning weight increased 19.78%(P <0.05).(3) sows and piglets Health: Experimental group premature farrowing rate, stagnant yields, lactation and breastfeeding Triad reduce the incidence of diarrhea and 4.71 percentage points respectively 12.5,12.5,25.0 weaned sows and weaning piglet body condition score increased 14.18% and 17.93%(P <0.05), respectively.(4) sow reproductive endocrinology: the test group pregnant sows to be empty with the secretion of estrogen hormone levels increase 21.39%(P <0.05), FSH and LH levels increased the trend.Test 3:(1) reproductive health: compared with the control group, the test group 1 and 2 groups of sows average litter size were increased by 0.24, 0.60, premature delivery rate decreased by 5 percentage points and 15 percentage points, the lag yield decreased by 5 and 10 percentage points, lactation triad incidence rate of two groups reduced by 10 percentage points; lactation and lactation quality have improved trend, among them, 1 test group and 2 group of colostrum milk protein increased 9.22% and 26.77% respectively(P<0.05), lactose increased 10.70% and 13.58%(P<0.05), 33.42%(P<0.05), milk fat increased 48.64%(P< 0.05); test 1 group and the 2 group of weaning sows body condition scores were increased by 24.12%(P<0.05) and 18.68%(P<0.05), 14 d after weaning estrus rate increased by 5 percentage points and 10 percentage points, the total fertility rate increased by 10 percentage points.(2) the growth of piglets and health: compared with the control group, experimental group 1 and group 2 piglets 25 days weaning weight were increased 6.99% and 12.82%(P < 0.05), average daily gain of 1.34% and 5.75%(P < 0.05); diarrhea incidence rate were reduced by 3.92 and 4.27 percentage points, the survival rate of 3.87 and 2.61 percent. Studies have shown that sows Wai in perinatal period and lactation period feeding "reproductive nutrients and herbal medicine-2”, can effectively promote the sow immune and reproductive function, improve health and reproductive performance of sows, and indirectly enhance the piglets growth performance and health status. Comprehensive comparison, the effect of the 2 groups is more obvious.Test showed that: "reproductive nutrients and herbal medicine" by conditioning sow reproductive endocrine function, balance the body’s level, can effectively promote the breeding sows estrus and pregnancy, improve health and reproductive performance, improve lactation performance, thereby indirectly enhance the growth performance of piglets. |
