Pig feeding, there are two ways, one is to use farm feed, what feed what; the second is to use the 'scientific method', with full-price feed.
The advantage of using farm feed is self-production and low cost. At the same time, because all organic feed, no added mineral feed and trace elements, and no added hormones, sedatives and antibiotics, so you can produce 'pollution-free' 'organic food' or 'green food 'The disadvantage of using farmyard feed is that it is not as nutritious as it should be.
The disadvantage is that the use of farm feed leads to incomplete nutrition, the pigs do not grow fast, the feeding cycle is long, and they are often threatened by a variety of infectious diseases and parasites.
Another kind of full-price feed to raise pigs, its advantage is to feed the pigs grow fast, three or four months can be out of the pen. And it saves the trouble of configuring feeds and saves time and labour. The disadvantage is that the price of feed is expensive and the cost of raising pigs is high. With full-price feed raised pigs or chickens, there is no 'local pig', 'local chicken' like the aroma, now more and more unpopular with consumers.
As we all know: the complete feed for pigs consists of three main parts: energy feed, protein feed and premix.
Energy feed
Energy feeds include corn, rice, wheat bran, rice bran, groundnut, dried cassava, etc., as well as wine lees, groundnut residue, tofu dregs, and corn stalks, liquorice dregs, sorghum stalks, wheat stalks, rice straw, groundnut stalks, peanut stalks, bean stalks, pasture grass, donggua stalks, lucerne stalks, pumpkin stalks, bean vines, chilli pepper branches and leaves, aubergine branches and leaves, cottonseed husks and other roughage feeds.
Corn and rice are high in energy, palatability and digestibility, but are expensive and not conducive to cost reduction. Other energy feeds and roughages are cheap, but have poor palatability, low digestive utilisation and some contain toxic and harmful substances.
Protein feed
Protein feed has fish meal, feather meal, blood meal, meat and bone meal and other animal protein feed and soybean meal, peanut cake, cotton cake, vegetable cake, tea seed cake and other plant protein feed. Fishmeal is a high-quality animal protein feed, soybean meal and peanut meal is a high-quality plant protein feed, its protein content is high, palatable, high digestive utilisation, but the price is expensive, farmers can not afford to use. Other protein feeds have low price, but bad palatability, low digestive utilisation, and some of them contain a lot of toxic and harmful substances.
Premix
Premix varieties as many as hair, quality varies greatly, but most of them contain high steel, high zinc, some also contain a variety of prohibited substances, such as hormones, sedatives and antibiotics, and the price is expensive, not conducive to the production of 'green' pollution-free livestock and poultry products and reduce the cost of polluting the environment at the same time.
