How to feed a pig
1. Several situations in which pigs need to be changed
Different developmental stages of ①: from suckling piglets to weaned piglets, from weaning piglets to growing pigs, from growing pigs to fattening pigs
Different material types of ②: change from granular material to powder material, from wet material to raw dry material, etc.
③ changes to feed from different manufacturers
The change of ④ feeding frequency: for example, from 4 times daily feeding of piglets to 3 times daily feeding of fattening pigs.
When ⑤ made its own feed, the main monomer raw materials changed.
two。 Specific methods of feed replacement
Top the old material with the new material every day, and change it all in 4 days. The method is as follows: on the first day, the new material is lhammer 4, the old material is 3max 4, the second day is new material, the third day is new material, and the fourth day is all new material.
In their own mixing, generally with the growth and development of pigs, the proportion of energy feed (such as corn) in feed gradually increased, while the proportion of protein feed (such as bean cake) gradually decreased. For example, if the proportion of corn in the feed formula increases from 60% to 70%, it will take 4-5 days to increase 2.0%-2.5% every day; bean cake should be reduced from 20% to 15%, which should be reduced by about 1% every day, and the rest should be adjusted with wheat bran, fine bran and other raw materials. the same is true when using concentrated materials to make full-price materials.

Management of young ducks (31-20 days old)
The management goal of young ducks is to cultivate strong and good physique. 1. To step up exercise, we should drive the ducks to walk slowly around the playground every day, or go outside to slowly drive grazing to strengthen their physique. People should get in touch with ducks more and improve their courage, so that they will not be afraid of shock when they enter the laying period. two。 The feeding of young ducks is a skeletal muscle stage, and the principle of nutrition in the breeding stage is that it should be low rather than high, and the principle of feed is that it should be coarse rather than fine.
