Management Techniques for Establishing, Feeding and Grouping Small Ear Pig Breeding
The management technology of the construction, feeding, and grouping of the small ear pigs in Minnan. It is a domesticated wild boar that has been domesticated and is now listed on the national list of livestock protection. There is a place in the Chinese pig breeds. The pigs are mainly distributed in the Yunnan region. It is full-bodied, wide-necked, short-trenched and full-body black. The biggest feature is the pair of upright black ears. Speaking of this, it is certain that many people in Yunnan can call out their names. Yes, it is the small ear pig in Yunnan.
The first thing that should be considered is the construction of pig farms in the Minnan Ear-ear Pig Farming. If a medium-sized pig farm is to be constructed in rural areas, it is necessary to rationally plan the layout, adapt to local conditions, and use the site scientifically and rationally. When choosing pig farms, the people should choose high-desert dryness, sunny weather, convenient transportation, and a place far away from the source of pollution, which will help prevent epidemics, have sufficient water resources, have good water quality, and have excellent soil quality and an appropriate area. How to arrange the layout of the pig farm? The author told the farmers that as far as possible, the pig house was facing south from south to south. In the winter, it would help to prevent cold winds. In summer, direct sunlight could be avoided and southeast wind could be caught. For the design of pig houses, choose a building material that has good insulation properties and is conducive to moisture and air permeability. The roof design requires good insulation and ventilation and ventilation. As much as possible, reduce the number of partition walls and the height of the partition wall, increase the number of windows and doors, and increase the area of ​​doors and windows so as to ensure air circulation in the house. The floor should have a certain degree of slope in order to ensure good drainage and prevent dampness.
In feeding, farmers need to insist on feeding green feed and compound feed. The feed should be varied and reasonable. Only reasonable matching of the green feed, rough feed, and fine feed of the pig can ensure the pig's need for various nutrients. To achieve a good palatability of the compound feed, easy to digest. In compound feeds, if there is more energy and protein, and fewer crude fibers, then the palatability is good and easy to digest; if there is less energy and protein, and more crude fiber is contained, the palatability is poor and difficult to digest. In combination with pig feed, it is better to use green fodder. Using high-quality forage grass to raise pigs can not only reduce feed costs, but also increase the lean meat ratio of pork, which can greatly increase the economic benefits of swine breeding. The main high-quality pastures suitable for raising pigs include: hn-mc Youyou Grain Pestle, hn-mc Youyou Forage Vegetable, and hn-mc You You Kuai Vegetable. In the pig's compound feed, different types of pigs are selected according to the different herds. Diet. In general, pigs, breeding boars and fattening pigs can use the fine material type, that is, concentrate feeds account for more than 50% of the total diet; breeding sows and gilts can use green materials, ie, green feed can account for More than 50% of the diet; rack piglets can use bran type, that is, bran feed can account for more than 50% of the diet. Pay attention to the relationship between dietary volume and feed intake. Measure the amount of feed available for dry matter content. According to the calculation of 2.5-4.5 kilograms of feed dry matter per 100 kilograms of body weight per day for pigs, the dry matter ratio of the three feeds for green feed, roughage, and concentrate feed should be 5:3:2.
How do farmers keep a good grasp of breeding groups? In the management of group management, the principle is to feed the pigs in groups with similar source, body condition, temperament, and feed intake, group management, and feed in separate tanks to ensure normal pig growth and development. The difference in weight of the same group of pigs should not be too large, the pigs should not exceed 3 to 5 kg, shelf pigs should not exceed 5 to 10 kg. After grouping, it should be relatively stable. Generally, it should not be arbitrarily changed. The average density of suitable weaning piglets per pens accounted for 0.7 square meters, and the finishing pigs were 1.2 square meters per head. Each group is suitable for 10 to 15 heads. In winter, the stocking density can be appropriately increased and the stocking density can be appropriately reduced in summer. The key to grouping by grouping methods is to avoid biting each other at the beginning of the group. According to the biological characteristics of the pig, we should stay weak and not stay strong, leave the weaker pigs in the original circle, and call out the strong ones; remove more and more without removing the pigs, keep the pigs in place, and keep the heads in place. A large number of pigs with less number of heads merged into one; when the nights do not merge together, the same medicine, such as alcohol, is sprayed on the pigs in the ring group so that the odors are not easily distinguishable and they are grouped together at night; Put the two groups of pigs together in a larger stadium, and then group them three to seven days later. When the hunger is removed and the pigs are hungered, the pigs are dismantled and fed immediately after the group is hungry. Not infringed.
The pig farm roads and environment should be kept clean and hygienic. Every day, the piggery should be cleaned, the troughs, sinks and utensils should be kept clean, the ground should be clean, and high-efficiency, low-toxicity, broad-spectrum disinfectant should be used for regular disinfection. The piggery should be dehydrated frequently, once a day, and kept dry. In summer, the number of defecations can be increased. After cleaning, rinse with water. However, it is not advisable to wash the water in the winter or the branch house and the nursery, and it should be kept dry. The manure can be removed by the lime powder and washed with a high-pressure water gun. The manger and the sink should also be kept clean. Before each feeding, the material left in the tank should be removed. Because the remaining material is easily corrupted, it should be washed clean. The sink should also be cleaned once a day. If it is a nipple drinker, it will be convenient and hygienic. After thorough cleaning, it should be disinfected on a regular basis. The summer barn should be fully disinfected at least twice a month and once in winter. Feeding tanks, walls, etc. should be regularly sterilized, but the feed tanks and sinks should be flushed with water once to remove the disinfectant. The pig farms also need to increase the amount of sunstroke-preventing cooling and cold-keeping facilities to ensure that pigs have appropriate venues and time for outdoor activities in order to increase the chance of the pigs basking in the sun. At the same time do a good job in the greening of pig farms.
