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 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, 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, 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 of 16°C to 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 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 save feed, reduce costs and increase economic efficiency purposes.
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 for increasing or decreasing feed or changing the feeding time, so that livestock and poultry meet the expected weight requirements to ensure the high yield of livestock and poultry. 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 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.
Reasonable application of 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 shown. 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 feeds Poor storage of feeds can easily cause moisture absorption, mildew, 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.
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, 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.
Ten ways to improve feed utilization
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 in quantity, and it is difficult to manage labor and time, and its work efficiency is low. For this reason, it is necessary to change the cows and sheep to be kept as captives all year round.
