How to adjust the feed formula of pig farms in winter?
After the beginning of winter, the temperature in all parts of the country has declined to varying degrees. Therefore, pigs need to increase their energy to maintain body temperature. Can they increase energy with sputum? Of course, it is feed. If the energy provided by the feed is insufficient, the pig will provide energy by breaking down the protein, which not only causes waste of feed but also increases the metabolic burden. Winter is a period of high incidence of disease on the farm, a decline in production levels, and a decrease in feed returns. It usually results in a 5-10% reduction in pig growth rate and a 0.1-0.2 increase in feed-to-weight ratio. After years of experience in the service of the farm, we believe that the pig farm can make proper adjustments to the feed formula while improving the performance of the pig and improve the efficiency of the farm. . In order to reduce feed waste caused by temperature drop, it can be solved by the following methods: 1. Improve feed net energy (digestive energy) by adjusting feed formula Among the commonly used feed ingredients, corn, wheat, broken rice, barley, sorghum, oil and other net energy (digestible energy) are higher, wheat bran, secondary powder, corn husk, rice bran, DDGS, etc. are relatively low. By increasing the amount of high-energy raw materials such as corn, reducing the amount of low-energy raw materials such as wheat bran, and improving the digestible energy 100-300 kcal under the premise of ensuring that other nutritional indicators remain unchanged. Under normal circumstances, by reducing or even not using wheat bran (the sow material must use the right amount of wheat bran) instead of corn can increase the digestion energy of 60-100 kcal, you have to use 1-3 oil (soybean oil) to put The energy is raised. (Generally, 1-3% is added to the lactating masterbatch, 2-3% is added to the suckling pig, and 0.5-2% is added to the growing and finishing pig.) In addition, because oil and fat and other energy feeds such as corn have higher energy, they also have lower heat gain. Adding fat to the feed not only increases the energy concentration of the diet, but also allows the pig to consume more energy at the same feed intake, and can improve feed utilization efficiency and provide various essential fatty acids. 2, the net energy (digestive energy) is unchanged, appropriate to reduce protein levels That is, the amount of protein materials such as soybean meal is appropriately reduced (1-3 points), and the corresponding amount of corn is used instead, thereby lowering the protein level by 0.4-1.0%, which also increases the energy protein ratio (or energy amino acid ratio). The premise of this method is that it must be able to ensure that the feed intake is improved, thus ensuring that the total nutrient intake is sufficient. For suckling pigs and lactating sows, feed intake is often insufficient and is generally not suitable for this method. 3, pay attention to corn moisture content Many pig farms use new corn in winter, the water is high, generally 16 water or even higher, the energy and protein levels are relatively low, it is best to test the conventional indicators, and then estimate the energy level, according to the actual nutritional indicators. Perform feed formula calculations. There is no corresponding testing personnel and testing equipment for the general pig farm. The moisture content can only be estimated by experience. It is higher than the 14% moisture content of the national standard corn, and the amount of other corn is increased by one more water. Although the total amount exceeds 100%, most of the excess is moisture. And the moisture of corn can't exceed 17%, otherwise it can not only be crushed, but also more likely to cause mildew. As the corn harvest mature and more rain this year, resulting in most of the corn mildew serious, this is a huge challenge to the pig industry, requiring farmers to strictly the procurement of corn, not only concerned with the post, put on quality first, the origin of good credit and auto shut off, and resolutely put an end to moldy corn admission. Of course, mildew is not measured alone the naked eye can see through, and some of the focus to special care, such as sow destination have added mold release agent detoxification, but now de-mold agent wide variety, quality varies not Qi, to select quality guaranteed products. 4, while doing the above adjustments, but also to ensure the health of the intestines Winter is a season of high intestinal disease. Intestinal diseases not only affect digestion and absorption, but also waste feed, and it is also the main cause of death. In order to ensure the health of the intestines, in addition to considering the nutritional needs of pigs, the feeds that are easy to digest and absorb are used, and the nutritional needs of the microbial flora are also considered, so that the intestinal microbes are in a stable and balanced state. This requires farmers to pay close attention to intestinal nutrition, and choose appropriate intestinal nutrition additives to ensure that the microorganisms and pigs achieve a healthy coexistence. Only by making the feed ratio the most scientific can the pig's production performance be improved and the economic benefits of the farm be improved.
