At present, the commonly used methods for raising pigs in rural areas include clinker dilute feeding method, raw material wet feeding method and dry material feeding method. The pros and cons are briefly introduced as follows for reference by the majority of pig farmers:
1, clinker dilute feeding method
The method refers to the method of feeding porridge to pigs after the feed has been cooked. Advantages: First, after the feed is cooked, the crude fiber is softened, which improves the digestibility of the roughage to a certain extent; second, it reduces the feed volume and increases the feed intake of pigs; and third, it has the effect of killing bacteria and parasite eggs. . Its disadvantages: First, most of the feed after cooking, the nutritional value is reduced, such as corn, barley, bran and other nutritional value of feed to be reduced by about 10%, in particular, many vitamins will be destroyed; Second, the green feed cooked Later, if handled improperly, it will also cause nitrite poisoning; Third, cooking and feed also need to consume burning grass or fuel to reduce the source of roughage, is not conducive to the development of the pig industry; Fourth, cooked feed needs room, pot, furnace and other equipment, Increased the cost of raising pigs; Fifth, the cooked feed is easily deteriorating, and it needs to be followed by cooking. It is expensive and costly. This law is still very common in the vast rural areas, but it is totally unsuitable for the specialized pig-raising households that have developed in rural areas.
2, raw wet feed
The method is to mix the crushed fine material, coarse material and other feeds according to the required ratio and total requirements before feeding, together with chopped or pulped green feed and water (generally, the ratio of material to water is 1:0.8). ~1. It is advisable to use a handful of drip in the mixture.) Mix it evenly to feed the pig. Advantages: First, the method is simpler than the clinker dilute feeding method, and more scientific; second, the province's firewood, provincial labor, and provincial equipment can reduce the cost of raising pigs; Third, the pig's growth and development is fast, robust, shiny coat, disease resistance Strong. Disadvantages: First, the feed should not be stored wet, but still need to be adjusted and fed; Second, the wet material is easy to freeze in winter, and it is still difficult to use the large pigs (fields) with a certain scale; third, it can not be further improved. Labor efficiency.
3, dry material dry feeding method
The method is to put the crushed coarse material in proportion and put it into the automatic food tank so that the pigs can freely feed. The feed can be added once a day, with a separate water tank and free drinking water. This method feeds pigs, and the pig farmers add feeds once a day. They usually add green feed and clean the pens in time. Not only greatly reduces labor intensity and improves work efficiency, but also the dry material is closer to the nutritional needs of pigs. In addition, pigs are free to eat without human influence, which can further promote the growth of pigs and increase the daily weight of pigs.
