Pay attention and learn more about pig farming together!
Now pig farmers need to buy feed when raising pigs, in addition to conventional energy feed, concentrated feed also needs to be purchased. Compared with corn and other energy feed, concentrated feed nutrition is more comprehensive, is indispensable for pig fattening, while the price of concentrated feed is relatively high, this article, we bring you a method of preparing concentrated feed for pigs, we write down, at home can be made, no need to buy anymore, can reduce breeding costs, so that pigs more profitable! If you have something you don't understand, you can also leave a message below, communicate together, if this article is useful to everyone, you can share and forward!
In order to facilitate everyone's understanding, we can first look at a feed formula (full-price feed formula) that we normally have in fattening pigs, and this formula can also be learned and very useful!
Full-price feed ratio: corn 50%, sorghum 10%, barley 10%, soybean meal 14%, fishmeal 7%, shell powder 4%, stone powder 2%, bone meal 2%, additive 0.5%, salt 0.5%, total 100%.
Through the above full-price feed formula, we can see that corn, sorghum, barley three kinds of energy feed, that is, to feed pigs, accounting for 70%, in addition to these 3 kinds, the next 7 kinds are concentrated ingredients, accounting for 30%. That is to say, the ratio of concentrated feed to energy feed is 3:7. (Of course, some pig farmers may use corn, sorghum, barley all three kinds of energy materials with corn, which is also possible, of course, it is better to use three.) ）
The most critical step in determining the ratio of concentrated feed to energy feed is to calculate the ratio of each component of concentrated feed.
Taking the 50 kg of concentrated feed we need to prepare, that is, 100 kg as an example, the content of soybean meal we need is: 14% ÷ 30% X100% = 46.67%, that is, 100 kg of concentrated feed contains 46.67 kg of soybean meal; the amount of fish meal required is: 7% ÷ 30% X100% = 23.33%, that is, 100 kg of concentrated feed contains 23.33 kg of fish meal, in the same way, we can get the content of shell powder, stone meal, bone meal, additives, salt, You can calculate, in order (13.33%, 6.66%, 6.66%, 1.67%, 1.67%). When preparing concentrated feed, we only need to multiply the above proportion by the total weight that needs to be formulated.
This section is shared here, have you learned? There is a message that I do not understand to solve.
