Improved feeding methods At present, a considerable number of farmers raise cattle and sheep to implement traditional grazing methods. Because of this feeding method, the livestock and poultry activities are large enough to maintain and meet the heat energy and various nutrient needs in the metabolic process. The amount is large, and the labor and time are difficult to manage, and the work efficiency is low. To this end, cattle and sheep must be changed to grazing for captivity.
Improved feeding methods At present, some pig farmers in rural areas are accustomed to feeding thinners. Due to excessive water addition, they limit the feed intake of pigs and reduce the digestibility of dry matter and feed utilization. If the feed thinner is changed to feed thick material, the feed utilization rate can be greatly improved.
Improved feed processing methods often result in nutrient losses due to improper feed processing methods and reduce the utilization of feed by livestock. 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%.
The implementation of scientific management of livestock and poultry breeding management conditions, in addition to directly affecting the health and growth of livestock and poultry, but 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.
The implementation of scientific limited feeding technology is based on the different growth stages of livestock and different production purposes, by increasing or decreasing feed or changing the feeding time, so that livestock and poultry can reach the expected weight requirements to ensure the high yield of livestock and poultry. performance.
The implementation of scientifically formulated rations Currently, the main reasons for farmers to raise livestock and poultry consume more materials and high costs: 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 protein supply 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 the feed is 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.
The use of heterosis and the selection of improved varieties have 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.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
