Early weaning of piglets can increase sow productivity and pen utilization. However, early weaning also causes pigs with poor appetite, indigestion, low feed utilization, reduced immunity, poor disease resistance, and diarrhea, leading to growth. Dysplasia. This article has a pig price network Xiaobian finishing release, remember the pig price network. In order to ensure that early weaned piglets have a higher growth rate, we must create good compensation conditions and take effective measures.
First, reduce weaning stress
One must feed early. Piglets are usually bred by piglets 7 days after their birth, so that the gastrointestinal system of piglets can adapt to plant feeds before weaning, and the gastrointestinal function can be strengthened to reduce the effects of nutritional stress. The second is to gradually carry out weaning, not a sudden weaning, 1-5 days before weaning to reduce the number of breast-feeding in order to reduce the impact of psychological stress. The third is to adopt the method of weaning and weaning the weaning, that is, weaning the sow and keeping the piglet in the original house. Pay attention to temperature, humidity and ventilation to ensure that piglets grow rapidly in a good growing environment to reduce the impact of environmental stress. Fourth, Beverage electrolyte aqueous solution, adjust the nerve - body fluid balance, increase body resistance, to reduce the stress response, increase the effect of weight gain. Aqueous electrolyte solution can refer to the following formula: pure glucose 25g, sodium chloride 4.5g mouth, sodium bicarbonate 2.0S, citric acid 0.3S, potassium acetate 0.2g, potassium chloride 0.05g, add water 1000ml.
Second, improve the immunity of piglets
Vitamin E plays an important role in maintaining humoral and cellular immune responses. Tests have shown that piglets are weaned at 21, 28, and 35 months of age. If vitamin E levels in the diet are required by the NRC regulations, vitamin E in blood after weaning before 35 days is significantly reduced, which is less than one-third of the level before weaning; At 20 times the level of vitamin E, whenever weaned, serum vitamin E levels not only do not decrease after weaning, but also increase. According to reports, vitamin E, which is 6 to 20 times higher than the NRC requirement, can improve the immunity of piglets, thereby enhancing the disease resistance of piglets and facilitating the healthy growth of early weaned piglets.
Third, the application of enzyme preparations
Enzyme preparations used in early weaned piglets can compensate for the lack of various digestive enzymes in the piglets, ensure normal digestion and absorption of piglets, eliminate indigestion and promote growth. Tests showed that adding enzyme preparations containing proteases, amylases, and lipases to basal diets and feeding 21-day-old piglets for 6 weeks resulted in a 16% to 23% increase in weight gain and 14% increase in feed intake. -20%. After 3 weeks of age, piglets were mixed with enzyme preparations after weaning, and the daily weight gain was increased by 24.6% over the non-addition, and the weight gain lkg less consumed 0.23 kg.
