Pig rearing tips farming technology pig rearing what to pay attention to

Pig rearing using scientific feeding methods, can reasonably utilize the feed, improve the feed conversion rate, so that the pig more long meat, quick to the pen. Therefore, pig feeding should grasp the following four points.

1. Raw and cooked feed. According to the characteristics of the feed type to decide to take raw or cooked feed. Should reduce the loss of feed nutrients, improve utilization, prevention of poisoning and disease as a principle. Legume seeds, rapeseed cake, cottonseed cake, potatoes and sweet potatoes and other concentrates and juicy feeds contain toxic substances should be. Cooked feed to prevent poisoning. Swill contains various unknown substances and should be cooked and fed. Corn, wheat, sorghum and all kinds of green feed should be fed raw.

2. thick feeding and thin feeding. Thin feeding because the feed contains more water, fast gastric emptying, gastrointestinal stimulation, resulting in reduced secretion of digestive juices, reducing the digestion and absorption of feed. For this reason, the feed for pigs should be fed raw and dry feed and raw wet feed. Fermented, silage, chopped and other processed feed to pinch together, scattered as appropriate. But after feeding to supply enough water.

3. Less and more meals. According to the type of pig, age, season and the nature of the feed to determine the number of meals. 7-day-old piglets entice unlimited number of meals; 20 days of age to weaning, you can feed more than 6 times a day; weaned piglets 4-5 times a day; sows with piglets and sows in the late stages of gestation 4 times a day; frame pigs, large meat pigs, boars 3 times a day. Hot summer days and nights are short and you can add 1-2 times as appropriate; winter days and nights are short and nights are long, then the first meal in the morning should be fed early, once in the evening fed late, and once at night with additional meals.

4. Feeding to "four". That is, fixed quality, fixed quantity, fixed time and fixed temperature. According to different age and use of pigs in accordance with the feeding standards formulated accordingly rations, the requirements of nutrition comprehensive and balanced, complete, diverse with a variety of palatable, good quality and fresh. Timing is conducive to the formation of habits, regular secretion of digestive juices, promote digestion and absorption of substances. According to the nutritional situation of the pig and appetite, to determine the amount of daily feed for pigs, generally to feed the trough after the food is not left, the pig does not lick the trough as appropriate. Spring, summer and fall are generally fed at room temperature, winter should be appropriate to use hot water to wither feed and feed warm water.

Pig farming is not only the traditional farming industry, but also the focus of livestock farming. Pork food is irreplaceable for other animal food, plus grain crops, vegetables and fruit cultivation requires a lot of agricultural fertilizer, the use of biogas must also raise pigs, so pig farming becomes more important.

Raising pigs is a systematic project, from the selection of seedlings, ingredients, management and disease prevention. To raise pigs well is not easy but not impossible. To raise pigs well, raise the benefits to, must master the scientific knowledge of pig farming, and in practice, constantly summarize and improve. To this end, the following is the main point of feeding and fattening of the proven technology to help pig farmers to raise pigs, and then raise a good economic benefits.

First, create good pig conditions

To make pigs healthy, fast growth, input and output proportional to the creation of good conditions, specifically to do the "four good", that is, "good seed, good material, good house, good management".

1, good breed: China's vast territory, geography, climate conditions vary greatly, the pig's local varieties, up to dozens. From the meat quality division, there are fat, lean, meat and fat type of pig. Fatty pig generally refers to the domestic local breeds, lean meat accounted for 35-45% of the carcass, such as the Quanhua pig, Neijiang pig, the two small-flowered pig; lean pig refers to the introduction of good varieties from abroad, lean meat accounted for 60-65% of the carcass, such as Changbai pig, large white pig, Duluo pig; meat and fat type of pig refers to the use of imported breed of pigs for the sire, the local good breeding sows for the female hybrids. The meat and fat type of pig refers to the use of imported breed of pig as the parent, the local breed of sows as the mother crossbreeding offspring, that is, hybrid pigs. This kind of pig has strong disease resistance, fast growth, high feed utilization and more lean meat. We are in the specific selection of seedlings, to select a large, high feet, well-proportioned body, touch the ear root without heat, no red spots, no dilution, feeding normal healthy pigs.

2, good food: to raise a good pig, we should figure out the nutritional needs of pigs and their functions, but also learn to recognize the real and fake, good and bad feed, to prepare fresh, nutritious and comprehensive high-quality feed for pigs.

3, good house: the construction of pig pens, to be selected in a relatively high ground, so as to facilitate drainage and defecation. At the same time, we should consider the light and air permeability, heat and cold. The size of the pen according to 1 pig occupies an area of 1.2 square meters, the length of the trough according to each head of 40 cm design. Ground level according to a show of defecation low, other triangular higher to maintain a certain slope auxiliary surface. This is easy to clean and flush clean.

4, good management: build a good column, choose a good seedling, ready to high-quality feed, it is necessary to carry out excellent management. First, triangular management, conditioning pigs to eat in one place, sleep in one place, pull in one place; second, diligent cleaning; third, accurate feed; fourth, pay attention to observe whether the pigs are sick; fifth, regular deworming and epidemic prevention.

Second, improve feeding methods

To make fattening pigs healthy, fast growth, in addition to the above "four good", in the feeding methods, but also to carry out the "four changes", that is, cooked to raw feed, sparse to wet and dry feed, a single feed to a mixed feed, random feeding to regular feeding, and the feed is not a good idea. The first thing you need to do is to change the feeder to a regular feeder.

1, cooked to raw feed: the traditional feed method is to cook the feed to feed pigs, feed in the process of cooking, the high temperature will destroy some of the nutrients, especially vitamins most of the loss. If cooked improperly, may also cause nitrite poisoning, resulting in pig death. Feed raw feed, both to ensure that the nutrients are not destroyed, but also to save labor and fuel, but also to prevent nitrite poisoning. In addition to potatoes, taro, pumpkin, cassava high starch feed cooked feed favorable digestion, other feed can be fed raw.

2, dilute to wet and dry feeding: pigs have dry feeding, dilute feeding and wet and dry feeding method. Dry feeding requires a lot of saliva and gastric juice wet feed, dry powder is also easy to cause laryngitis and make pigs choking; sparse feeding look up pigs eat a lot, but the growth is very poor. Because one is more water to dilute gastric juice is not conducive to digestion; two is too much water to increase the burden on the internal organs, fast excretion, excretion is large, affecting the digestion and absorption of feed; three is not enough water nutrition, can not accurately grasp the amount of feed. Wet and dry feeding method, the concentration is generally like porridge, feeding gastric juice can play a good role in decomposition, promote the digestion and absorption of feed, so that the pig grows fast, high pay.

3, a single feed to mixed feed: the traditional feeding method is to have rice bran to feed rice bran, sweet potatoes to feed sweet potatoes, corn to feed corn, in a word, what to feed a single feeding.
