At present, in the rural courtyard pig production, mainly for finishing pigs, the number of breeding is small, generally not more than 10, but due to the lack of proper breeding and management techniques, so that pigs grow slowly, the disease continues to occur. In order to obtain higher production efficiency and maximize pig production potential, it is recommended that the following five issues should be noted in the rural garden aquaculture process: 1, scientific cooperation with diet In rural areas, there are a wide range of feed sources and a wide variety of sources, especially green and juicy. In order to increase the palatability of pigs for various feeds, the feed should be properly processed and prepared. Commonly used methods for processing feed preparation include: crushing, chopping, and beating the green and juicy feed; cooking high-starch feed and crushing high-energy seed feeds. Tests have shown that the digestibility of the green, juicy, feedstuffs is 49.2%, and that after chopped and fed, the digestibility is significantly increased to 63.5%. The growth of pigs requires various nutrients, and the composition and content of nutrients contained in various feeds are different. However, in a single feed, nutrients are often not comprehensive enough to meet the needs of the pig's growth and development, while in rural areas they often ignore this problem, and do not pay attention to the reasonable combination of various feed applications, often using one or two In feeds, the lack of certain nutrients often affects the growth and development. Therefore, in order to raise the pig's production level and obtain a higher slaughter rate, it is necessary to cooperate scientifically with the diet. Practice has long proved that using a variety of feeds to scientifically match pigs is more effective than feeding a single feed. many. Specifically how to tie in the diet, because of the different sources of feed, the types of feed are different, and there is a certain price difference in the same feed in different regions. Therefore, when formulating a feed formula with a diet, it is necessary to adapt to local conditions, according to the local The actual situation, flexible and rational use of a variety of existing local feed. At present, feed formulations are provided at the same time as the use of concentrates or premixes, which has certain reference value. 2, improve the feeding method In the rural areas, especially in the cold winter in the north, pigs are often fed with rare materials, and often the feed is cooked before feeding. This virtually destroys the original nutrients in the feed. After the feed is cooked, almost all of the vitamins are destroyed, such as long-term high temperature cooking, will degenerate the protein in the feed and reduce its utilization rate; at the same time, it is extremely prone to nitrous acid. Salt poisoning. Therefore, to change the traditional feeding method, from cooked to raw. When adopting raw feeding, scientific feeding methods should be selected. Generally in rural areas, more use of wet mix, that is, with water or boiled water mixed with the mixing material, adjusted to wet mix, material ratio of 1:1. Then directly into the trough for pigs to eat freely, this feeding method has the advantage of: can improve feed palatability and reduce feed waste. It should be noted that in order to prevent mildew and spoilage in the summer, it should be freshly mixed. In areas where conditions permit, raw dry powder can also be used, that is, the crushed fine and coarse feeds are uniformly mixed into an automatic trough for pigs to feed freely, and then the feed is added at intervals. This feeding method is simple and the feed is not easily deteriorated. , but also can save labor, but should pay attention to the separate water tank for pigs to drink water. Raw food should pay attention to the problem: avoid dilute feeding. In dilute feeding, it seems that pigs eat a lot. In fact, most of the food eaten by the pigs is water, which causes water saturation and adversely affects the physiological functions of the pigs. As a result, the feed has a short residence time in the gastrointestinal tract, excretion is quick and consumes much heat energy, which affects the digestion and absorption of the feed and reduces the utilization of the feed. 3, timely supply of drinking water Water is one of the important components of the pig body. Water accounts for approximately 1/3 to 1/2 of the water in the pig, and the body water of the newborn piglets can reach 80.3% of body weight. Water plays an important role in physiological functions such as digestion, absorption, transportation, body fluid secretion, waste excretion, and body temperature regulation. To do this, sufficient and clean water must be supplied daily. The water requirement of pigs varies with the season and the type of feed. Pigs need more water in summer, less water in winter, more water to feed dry powder, and less water to feed thick materials. Such as lack of drinking water, will affect the body metabolism, growth, pregnancy and lactation and other physiological activities, a direct impact on the farm production level and economic benefits. The method of water supply, currently in the production of pigs in rural courtyards, is generally to set up sinks in the stadium. The disadvantage is that sometimes the pig excretes feces and urine in the water tank, and the water in the summer water tank easily deteriorates. For this reason, the water in the sink must be changed frequently. The sink should be brushed and grounded. The nipple drinker should be installed wherever possible. 4, reasonable control of the environment In most parts of China's rural areas, due to the relatively simple construction of shacks, the shading in summer and the lack of insulation in winter have seriously affected the growth and development of pigs. Therefore, we must timely adjust the temperature and humidity, do summer heatstroke, winter cold work. In the summer, the weather is hot. While enhancing ventilation, you can take a arbor on the playground. The author used shading net shade to achieve good results. It can also be used to sprinkle water on the pigs and cool the floor of the pighouse. However, be careful not to rush the head when spraying the pigs. In winter, the temperature is low and the temperature difference between day and night is big. It is necessary to do a good job of wintering management. Attention should be paid to the following issues: First, repair the pigsty and block the air leakage in order to prevent it from being deterred. Secondly, pad the hay in the pigsty to prevent the grass from getting wet. Third, in order to increase the temperature inside the pig house, a method of building a plastic greenhouse can be adopted. This is a method often used in the cold regions of northern China. 5. Establish an epidemic prevention system At present, in our country's rural garden pigs, we do not realize the importance of disease prevention. Usually do not pay attention to routine immunization work, daily management in the pens is not sterilized, even if the disinfection is so-so, disinfection is not thorough, and severe epidemics often lead to the epidemic. In order to completely change this unfavorable passive situation, it is necessary to establish a reliable disease prevention and control system. First of all, adhere to the sanitation and disinfection work, we must maintain cleanliness and hygiene of the environment inside and outside the housing. At the same time, do a good job of vaccination according to the epidemic prevention program and ensure that the vaccination effect is reliable and reliable. The main infectious diseases that need to be prevented are: swine fever, swine pneumoconiosis, paratyphoid fever, foot-and-mouth disease, piglet jaundice, white piglets, pseudorabies and some common parasitic diseases.
