Improved feeding method
At present, a considerable number of farmers raise cattle and sheep to implement traditional grazing methods. Because of this feeding method, the amount of livestock and poultry is large, and it is necessary to maintain and meet the heat energy and various nutrients required in the metabolic process. Moreover, it is difficult to manage and time-consuming, and the work efficiency is low. To this end, cattle and sheep must be changed to grazing for captivity.
Improved feeding method
At present, some pig farmers in the rural areas are used to feeding thinners. Due to excessive water addition, the pigs' food intake is limited, and the digestibility of dry matter and feed utilization are reduced. If the feed thinner is changed to feed thick material, the feed utilization rate can be greatly improved.
Improved feed processing method
Due to improper feed processing methods, it often causes nutrient losses and reduces the utilization rate of livestock and poultry. Therefore, it is very important to pay attention to the improvement of feed processing methods and improve the effective utilization rate of unit feed. Generally, in the legume feed, substances such as antitrypsin are contained, which affect the digestion and absorption of the protein, but after heat treatment, the antitrypsin can be inactivated, thereby improving the utilization of the protein. The finer the grain feed is, the higher the digestibility, but too fine will reduce the palatability of the feed. If the comminuted grain feed is processed into pellet feed to feed the livestock, the utilization rate of the feed can be increased by about 23%.
Scientific management
The management conditions of livestock and poultry breeding, in addition to directly affecting the health and growth of livestock and poultry, also affect the utilization of feed. According to the test, poultry at the temperature of -10 ° C, the heat energy emitted at 10 ° C is 28% higher, in winter, livestock must be allowed to live in a relatively dry, warm housing, in order to reduce their body temperature loss and body nutrition Consumption. According to foreign data, pigs have the highest daily gain 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 kg of weight gain is increased by 1 at the optimum temperature. Times, therefore, as long as according to the different physiological requirements of livestock and poultry, to create appropriate living environment conditions, in order to maintain body temperature balance and reduce heat loss, to save feed, reduce costs and improve economic efficiency.
Implementing scientific limited feeding techniques
The method is to ensure that the livestock and poultry achieve high yield performance by adopting methods of increasing or decreasing feed or changing feeding time according to different growth stages and different production purposes of livestock and poultry.
Scientifically formulated diet
At present, the main reasons for farmers to raise livestock and poultry consume more materials and high cost: First, the feed is single and the nutrition is lacking. According to the test, each pig can be fed with compound feed to increase feed compensation by more than 20%. Second, it is not possible to scientifically formulate dietary nutrition levels according to different ages and weight growth stages of livestock and poultry. The implementation of scientifically formulated diets is an effective way to save feed and improve feed utilization.
Reasonable application of feed additives
In recent years, with the continuous development of feed additive research, it has become increasingly important to cooperate with the addition of feed additives in the diet. In the basic diet of livestock and poultry, adding some amino acids, vitamins, minerals, deworming health care drugs, etc., can not only improve the full price of the diet, but also reduce disease, ensure the health of livestock and poultry, promote growth and development, and improve Feed utilization has a significant effect.
Guarantee the supply of protein
Protein feed is an indispensable nutrient for the growth and development of livestock and poultry. According to the test, the broiler chicken was fed with a feed containing 18% crude protein, and 0.5% of lysine was added, which was 24% more than that without addition.
Do a good job in the storage and storage of feed
Poor storage of feed, prone to moisture and mildew, or insects. The feed is mildewed, the feed value is not only reduced, but also the feed poisoning is very prone to occur, resulting in the occurrence or death of livestock and poultry. The feed is stored for a long time. Although it is not mildewed, the nutrients will be reduced due to the deterioration of fat. Vitamin A, vitamin D and vitamin E are also easily oxidized to reduce the effectiveness. Therefore, it is not advisable to purchase too much feed once, and the purchased feed is still too much. It is necessary to pay attention to avoiding light, ventilation and moisture, so as to avoid causing mold loss; it is also necessary to strengthen the management of stock feed to prevent insects or being eaten by rats in order to improve the utilization of feed.
Use heterosis to select good varieties
Practice has proved that the higher the productivity of livestock and poultry, the less the consumption and the lower the cost. In recent years, with the cultivation and introduction of improved varieties, it has been very significant to save feed and improve feed utilization. In short, there are many ways to save feed to improve feed utilization, and it involves a wide range of methods. Only in the practice of raising livestock and poultry is good at constantly summing up experience, and will create more effective ways to save feed and improve feed utilization.
