Improved feeding methods At present, a considerable number of rural sheep farmers adopt traditional grazing and feeding methods. Due to the large amount of activity of livestock and poultry, this type of feeding method is used to maintain and meet the heat energy and various nutritive substances needed in metabolic processes. It is large, and it is difficult to manage due to time and labor. For this reason, it is necessary to change the cows and sheep to be kept as captives all year round. Improved feeding methods At present, some rural pig farmers are accustomed to feeding thinner foods. Due to excessive water intake, the pigs' food intake is limited, and the digestibility of dry matter and feed utilization rate are reduced. If the feed thinner is changed to thick feed, the feed utilization rate can be greatly improved.
Improve feed processing methods Pay attention to the improvement of feed processing methods and improve the effective utilization rate of unit feed is very important. Generally in legume feed, contains anti-trypsin and other substances, affect the digestion and absorption of 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%.
The scientific management of livestock and poultry raising and management conditions will not only directly affect the health and growth of livestock and poultry, but also affect the utilization of feed. According to experiments, livestock and poultry at the temperature of -10°C are 28% higher than those emitted at 10°C. In winter, livestock and poultry must be allowed to live in relatively dry and warm housing in order to reduce their body temperature loss. The consumption of nutrients in the body. According to foreign reports, pigs have the highest daily gains at temperatures between 16°C and 21°C. If the temperature is below 4°C, the weight gain is reduced by about 50%, and the feed consumption per kilogram of weight gain is increased by 1 at the optimum temperature. Times, therefore, as long as in accordance with the different physiological requirements of livestock and poultry, to create a suitable living environment for them, can maintain body temperature balance and reduce the loss of heat energy, to achieve the purpose of saving feed, reduce costs and increase economic efficiency.
Implementing scientific feed restriction technology This method is based on the different growth stages of livestock and poultry and different production purposes, by adopting methods of increasing or decreasing feed or changing the feeding time, so that livestock and poultry meet the expected weight requirements to ensure their high yield performance.
Implementing Scientific Formulation of Diets At present, the main reasons why farmers keep livestock and poultry consume a lot of materials and have high costs are as follows: First, there is a single feed and nutrition is lacking. According to experiments, each pig feed formula feed than to feed a single feed to increase feed conversion rate of more than 20%; Second, can not be in accordance with the different ages and weights of livestock and poultry growing stage scientifically formulated diet nutrition level. The scientific formulation of diets is an effective way to save feed and increase feed utilization.
Rational use of feed additives In recent years, with the continuous development of research on feed additives, the importance of adding feed additives to diets has become more and more apparent. 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.
Ensure protein supply Protein feed is an indispensable important nutrient for livestock growth and development. 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.
Doing a good job of storage and storage of feed The moldy feed will not only reduce the value of feed, but also cause feed poisoning, resulting in the onset or death of livestock and poultry. If the feed is stored for a long time, even if there is no mildew, the nutrient components will be reduced due to fat deterioration. Among them, vitamin A, vitamin D, and vitamin E are also easily oxidized to reduce the effectiveness. Therefore, it is not advisable to purchase feeds at one time and the purchased feeds are not 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.
The use of heterosis and the practice of selecting good breeds have proven 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, the role of saving feed and improving feed utilization has been very significant. In short, only in the practice of raising livestock and livestock is good at constantly summing up experience, will create new and more effective ways to save feed and improve feed utilization.
