How to increase the weight gain of pigs
Every pig farmer wants to raise a good pig, so we need to know where to start. Here are some suggestions for your reference: Add feed additives: 1. Feed calcium formate weight gain. The use of calcium formate as feed additive for piglets can promote appetite and reduce diarrhea rates in piglets. During the first few weeks after weaning, adding 1.5% calcium formate to the feed can increase the growth rate of piglets by more than 12% and increase feed conversion by 4%. 2, feeding zinc weight gain. Zinc is an integral part of many enzymes, proteins, and nucleic acids in animals and is involved in the metabolism of nucleic acids, proteins, carbohydrates, and fats. Adding 0.02-0.025% zinc oxide to the piglets' daily sugar can increase the daily weight gain by 15-20%, reduce the weaning diarrhea rate by 5-8%, and reduce the death rate by 3.1-5.5%. 3, feeding rare earth weight gain. Rare earth has a role in promoting growth and health of pigs. Adding 600ppm (ie, 6g of 10kg daily sugar) to the sugar on the basis of the fattening storage, the average daily weight gain increased by 13.76%, the feed efficiency increased by 13.75%, the post-mortem carcass weight increased by 14.24%, and the meat quality was good. 4, feed zeolite weight gain. Zeolite contains 18 essential elements and trace elements necessary for pig growth and development, and is easily absorbed and utilized by pigs. Adding 5-6% zeolite powder to pig feed can increase weight gain by 16%, reduce gastrointestinal disease and reduce odor. Similar to physicochemical characteristics of zeolites such as Maifanite, Bentonite, Bacite, Sepiolite, Marble, etc., it also has a good growth promoting effect. 5, feeding saccharin weight gain. There are 15,000 taste cells in the mouth and tongue of pigs, which are sensitive to sweetness. In the compound feed for pigs, 0.05 g of saccharin was added per kilogram of feed, which could mask the unpleasant taste of pigs in feed, increase appetite, increase feed intake, increase daily gain by 7%, and reduce feed consumption by 4.8%. 6, feed organic acid weight gain. The addition of 1.5-2% citric acid or other organic acids to the piglet diet can reduce the pH in the stomach of piglets, activate pepsin and other digestive enzymes, improve digestion, kill harmful bacteria, improve feed palatability, and increase Feed intake. The weight gain can be increased by 11%, and the feed utilization rate can be increased by 7%. 7. Feeding yellow fungine weight gain. Starting from the time piglets grow to 35 kg, adding yellow pigment to pig feed can increase the daily gain by 7% and the feed conversion rate can be increased by 5%. The amount added was 20 mg per kg of feed for piglets and 5 mg for finishing pigs. 8, feed yeast weight gain. The protein contained in yeast is rich in B family, and can help digestion and improve feed utilization. Adding 5-10% of feed yeast to swine feed can increase pig weight gain by 15-20%, reduce feed consumption by 10%, and significantly increase lean meat percentage. Improve environment, adjust nutrition, strengthen management 1. Maintain appropriate temperature and humidity Pigs can reduce the stress caused by temperature and humidity under suitable conditions of temperature and humidity, and the basal metabolism used to resist adverse stimuli is low. 2, enough water for drinking enough water. Water is the best solvent and transportation tool for all kinds of nutrients. Excluding waste in the body is also run through water. Adequate drinking water is the guarantee for the normal growth of pigs. Therefore, clean drinking water can be supplied at any time, and 0.5% saline can also be consumed. 3. Adjusting the diet The growth rate of the diet can be increased by adjusting the diet at different growth stages and under different environmental conditions. During the midsummer period, the energy feed in the diet should be relatively reduced and the green feed can be increased. Normal energy feed is 50-70% of the diet, summer is 40-50%; green feed is increased from 0.5-1 kg to 1-1.5 kg. The feed should be fresh and free from mildew. In winter, attention should be paid to the adequate supply of feed energy, which helps the pigs to resist the harsh stimulation of the winter. 4. Feeding at night for feeding at night will help the pigs gain weight. The method of feeding 3 times a night can be used. Feeding food at 7 o'clock in the evening, 11 o'clock in the night and 4 o'clock in the morning, as long as the feed is fed Feeding is reasonable, and the daily gain of a pig that needs about 50 kilograms can reach 0.5-0.75 kilograms. 5, a few special feed (1) vinegar or sauerkraut juice: Each time can be taken orally, according to the size of pigs increase or decrease. (2) White Lentils: It has the effect of relieving summer heat and strengthening stomach, and it can use 20-50 grams according to the weight of the pig to make Jianzhi Yintang. (3) mung bean soup: take the amount of green beans, add water, cook 20 times until the skin is rotten, cool, drink soup to eat beans. (4) Add plants with plantain and light bamboo leaves to decoct into soup and mix with the feed to feed the pigs. (5) watermelon rind: 2 kg of fresh watermelon rind, 100 grams of sugar mixed with mash, 1 time a day, in addition to feed more heat feed and additives, such as wheat bran, bean cake, peanut cake, artificial salt, etc. According to the conditions, it can choose to add as much as possible, and feed as little as possible hot feed such as sorghum, melon stem, cottonseed and distiller's grains. 6, good health, pay attention to ventilation. All ventilation holes should be opened in the pig house to make the pig cool and comfortable. The clean sand can be laid within 3-5 cm thick and the heat is removed through the contact between the pig body and the sand. Disinfect wall and floor with 20% lime milk weekly and disinfect all the feedstuffs with 3% stone carbonate solution. New method: China's animal husbandry scientific research personnel recently invented the "acupuncture points and intramuscular injection of pigs to promote the strong method", through the use of vitamin B12 and vitamin B6 added protein injection submandibular acupuncture points, vitamin B1 and muscle protein added to the protein for intramuscular injection , It can improve the feed utilization rate and promote the growth of pigs, so as to achieve the effect of saving costs and quickly accelerating.
