Concentrated feed is easy to use and has good economic benefits. At the same time, it can make full use of the energy feed and its processing by-products in the hands of pig farmers. However, in the use of concentrated feed, there are often some problems that are easy to be ignored by everyone. Today, I will tell you about the problems that should be paid attention to when using concentrated feed.
Concentrated feed is a mixture of protein feed, mineral feed, trace elements, vitamins and non nutritive additives in a certain proportion. The concentrate feed we bought for pigs generally contains more than 30% crude protein, and the mineral and vitamin contents are more than 2 times of the pig's requirement. Therefore, we can't feed them directly. We can only feed them with a certain proportion of energy feed (or add a small amount of protein feed) to make a full price compound feed or concentrate supplement, so as to play its real role Utility.
The label contents of concentrated feed include product name, feeding object, product registration number or approval number, main feed raw material category, nutrient content guarantee value, usage and dosage, net weight, production date, factory name and address. Because the use of concentrated feed from different manufacturers may be different, it can be assured according to the proportion in the manual. The contents of the instruction include recommended feed formula and feeding method, expected feeding effect, preservation method and precautions, etc. The product qualification certificate shall be provided, and the inspection personnel's seal and inspection date shall be stamped.
We should purchase the corresponding concentrated feed products according to the variety, use and growth stage of livestock and poultry. We should not use the concentrated feed of chicken for pigs, nor feed the concentrated feed of pigs to chickens. Of course, we should not use the concentrated feed of breeding pigs for fattening pigs.
Under the same nutrition level and feeding management, the growth rate, feed conversion rate and carcass quality of different breeds of pigs were different. Therefore, when farmers choose to use feed, they should choose different grades of concentrated feed according to their pig breeds. If it is a mating line, such as binary or ternary cross. This kind of pig has fast growth speed and high feed conversion rate, so we should choose to use the stall feed to improve the productivity.
Some farmers in the pig price rise, in order to let the pig grow faster, ahead of time, blindly increase the concentration of feed. In this way, the protein in the feed will increase, but the energy will be reduced. The protein can not be fully utilized and absorbed by pigs, which will cause indigestion and even rarefaction in pigs. It is not advisable to adopt the method of "Haste makes waste". There are also some farmers, in order to reduce the cost of concentrated feed when the pig price is low. This is easy to cause the lack of nutrients, resulting in the growth of pigs hindered, poor development. If the feed ratio of feed to meat ratio increases, not only the cost can not be reduced, but also the cost will be increased.
There are some farmers in the ingredients often add less concentrated material, with soybean or soybean cake instead, in fact, this is not good. Because soybean and soybean cake are protein feed, which are used to replace concentrated feed, only make up for protein feed, and reduce the concentration of additive premix and constant mineral feed in mixed feed, which will lead to unbalanced nutrition and affect feeding effect.
There are also some farmers with seasonal changes to adjust the formula, in fact, the problem is not big, but should pay attention to appropriate. In the low temperature season in winter, the energy required by pigs to maintain body temperature increased, and the proportion of energy feed could be appropriately increased. In hot summer, the ratio of energy feed to protein feed can be reduced appropriately.
It is not necessary to add any feed additives (except for the drugs added to prevent specific diseases) in the preparation of concentrated feed. When feeding, it should be mixed with crushed energy feed, fed with raw material, and provided with enough clean drinking water.
