1, feeding a well-fed full-price diet Promote the digestion and absorption of the diet by the herd. The cold feed has a great influence on the herd in winter. Try to feed dry powder or feed with warm water. If necessary, provide clean warm water for pigs. Free to drink. 2, adjust the feeding system, increase the number of feeding The purpose of increasing the number of feedings is to increase the feed intake relatively to fill the weight loss caused by fat and intramuscular metabolic heat production in pigs due to low temperature. For qualified farms, it is best to take free food. Winter nights are long and feeding time should be arranged in advance feeding and late feeding or night feeding. 3, improve feed energy levels In winter, due to the increase in the maintenance of the body, the energy level of the diet can be appropriately increased, which can be increased by about 10% based on the original feed energy level. Big pigs are low and pigs are high. Piglets can be added with high-energy feeds for oils and fats. Large pigs can increase the amount of ordinary energy feed such as corn in the batch. 4, to ensure the quality and quantity of Do not feed mold, deterioration, spoilage, freezing, toxic and other feeds. In winter, try to "time, quantitative, qualitative, fixed temperature" feeding. 5, the sow is implemented in stages to feed Under the premise of ensuring the nutritional needs of sows at different physiological stages, the nutrients and feed intake should be reasonably increased and decreased, and the fertility of sows in winter should be improved.
Body armor plate decelerated fragmented and deformed by the insert plate and any fragments are captured, the Ballistic Material is Kevlar vs UHMWPE. Perfect design for wearing, good at body engineering, soft and comfortable. Also the carrier in high strength nylon fabric. The armor plate is laminated with PE UD or Kevlar fabric. Different protection level standard requires different lamination technique. The armor plate features in light weight, good bulletproof performance, anti-chemical erosion, UV resistance, and waterproof. It is the lightest armor plate material at home and abroad. The bullet proof ceramic plate can give more flexibility and spare energy for wearers when equip them in Bullet Proof Vest, school bag, suitcase or any other place need ballistic protection.
