(I) Improve feeding methods. At present, a considerable number of peasant cattle farmers adopt traditional grazing and feeding methods. Because of the large amount of activity of livestock and poultry, this type of husbandry provides a large amount of heat energy and various Nutrients needed to maintain and meet metabolic processes. Time-consuming and difficult to manage, work efficiency is low. For this reason, it is necessary to change the cows and sheep to be kept as captives all year round. (b) Improve feeding methods. At present, some rural pig farmers are accustomed to feeding thinner materials. Because of excessive water intake, the pigs' food intake is limited, and the dry matter digestibility and feed utilization rate are reduced. If the feed thinner is changed to thick feed, the feed utilization rate can be greatly improved. (c) Improve feed processing methods. Due to improper feed processing methods, it will often cause nutrient losses and reduce the utilization of feed for livestock and poultry. Therefore, it is very important to emphasize the improvement of feed processing methods and improve the effective utilization rate of unit feed. Generally in legume feed, containing anti-trypsin and other substances affect the digestion and absorption of the protein, but after heat treatment, can make anti-trypsin failure, thereby increasing the utilization of the protein. The finer the cereal feed is, the higher the digestibility is, but the fineness will reduce the palatability of the feed. If the crushed grain feed is processed into pellet feed for livestock and poultry, the utilization rate of the feed can be increased by about 23%. (D) the implementation of scientific management. In addition to directly affecting the health and growth of livestock and poultry, livestock and poultry husbandry and management conditions also affect feed utilization. According to experiments, poultry at a temperature of -10°C is 28% higher than that emitted at 10°C. In winter, livestock must be allowed to live in a relatively dry and warm housing in order to reduce body temperature loss and body nutrition. The consumption. According to foreign reports, pigs have the highest daily gains at temperatures between 16 and 21°C. If the temperature is below 4°C, the weight gain will be reduced by about 50%, and the feed consumption per kilogram of weight gain will be doubled at the optimum temperature. , Therefore, as long as the different physiological requirements of livestock and poultry, to create a suitable living environment conditions for them, in order to maintain the balance of body temperature and reduce the loss of heat energy to achieve the purpose of saving feed, reduce costs and increase economic efficiency. (V) Implement scientific feeding restriction techniques. This method is based on the different growth stages of livestock and poultry and different production purposes, by adopting the method of increasing or decreasing feed or changing the feeding time, so that the livestock and poultry meet the expected weight requirements to ensure the high-yield performance of livestock and poultry. (6) Implement scientifically formulated diets. At present, the main reasons why farmers keep livestock and poultry consume more material and have higher costs are as follows: First, there is a single feed and nutrition is lacking. According to experiments, each pig feed formula feed can raise the feed remuneration more than 20% than feeding a single feed; Second, it can not be scientifically formulated dietary nutrition levels according to different ages and weight growth stages of livestock and poultry. The scientific formulation of diets is an effective way to save feed and increase feed utilization. (7) Rationally applying feed additives. In recent years, with the continuous progress of research on feed additives, the importance of adding feed additives to diets has been increasingly demonstrated. Adding some amino acids, Vitamins, minerals, insect repellent health care drugs, etc. in the basic ration of livestock and poultry can not only improve the full price of rations, but also reduce disease, ensure the health of livestock and poultry, and promote growth and development. Feed utilization has a significant effect. (8) Ensure the supply of protein. Protein feed is an indispensable and important nutrient for the growth and development of livestock and poultry. According to experiments, broilers were fed with a diet containing 18% crude protein, and 0.5% lysine was added, and the weight gain was 24% more than without. (9) Do a good job of storing and keeping feed. Poor storage of feed, prone to hygroscopic, moldy, or worms. Feed moldy, feed value is not only reduced, but also prone to feed poisoning, resulting in the incidence or death of livestock and poultry. If the feed is stored for a long time, although no mildew will result in deterioration of the nutrients due to fat deterioration, vitamin A, vitamin D, and vitamin E are also likely to be oxidized to reduce efficacy. Therefore, it is not advisable to buy feeds at one time and the feeds purchased should not be excessive. Attention should be paid to avoiding light, ventilation, and moisture, so as not to cause mildew loss; it is also necessary to strengthen the management of stock feeds to prevent worms or be stolen by rats in order to increase feed utilization. (j) Use heterosis to select good breeds. Practice has proved that the higher the productivity of livestock and poultry, the lower the consumption of materials and the lower the cost. In recent years, with the cultivation and introduction of improved varieties, it has become very significant to save feed and increase feed utilization. In short, there are many ways to save feeds and improve feed utilization, and they involve a wide range of aspects. Only by continuously summarizing experience in the practice of livestock and poultry breeding can we create new and more effective ways to save feed and increase feed utilization.
