When we raise pigs, we all hope that the pigs we raise can grow healthily and quickly, grow a body of pork and buy a good price. But things are not as good as we think. Many pigs grow at an average speed, so we will use some fattening methods to fatten the pigs when we raise pigs. However, the pig raising equipment here reminds us that many people make pigs fatter The fattening methods used are all wrong, so the effect of pig fattening is not very good, and even the value of pig to us is far lower than the cost of feed we pay. So how can we avoid the wrong way of fattening?
Many pig farmers in the pig fattening stage a lot of soybean cake or peanut cake, think that this feeding pig ability to grow fast, meat is strong, in fact, this is wrong. At the stage of fattening, the focus of pig growth is to grow fat, not muscle, so it does not need a lot of protein feed. If a lot of protein feed is fed in the fattening stage, it is necessary to remove the nitrogen part of the protein in the gastrointestinal tract of pigs, and other nitrogen-free parts can be converted into fat, but denitrification requires more energy. In addition, the soybean cake or peanut cake contains a lot of unsaturated fatty acids, which can make the fat of the pig soft and yellow after being fed more. It will not make the meat strong at all, but will reduce the quality of the meat. Therefore, we should not only add some fat containing fertilizer to pigs, but also some protein containing fertilizer to promote the absorption of protein in pigs, so as to prevent the above situation.
The focus of pig breeding is to quickly increase the weight of pigs. Now many people use pig breeding equipment to carry out auxiliary breeding. However, the use of pig breeding equipment can only make the management of pigs more worry free, and can not directly and quickly increase the weight of pigs. Therefore, we should pay more attention to the above-mentioned minefields when we increase the weight of pigs to avoid bad impact.
