According to the data of Agricultural Encyclopedia, the approximate feed required for a pig to slaughter 300 kg is as follows:

1. Raising a pig to 300 kg is related to the feed type selected by farmers, because different feeds have different feed-to-meat ratios.

2. If it is premix, the feed-meat ratio is about 3: 1. If it is concentrated, the ratio of feed to meat is about 2.8: 1. If it is a complete feed, the feed-meat ratio is about 2.6: 1.

3. Taking feeding concentrated feed as an example, if piglets weigh about 20kg when entering the stall, about 150kg when leaving the stall, and their weight * * * increases 130kg, they need to be fed concentrated feed of 130×2.8=364kg.

4. Feed-to-meat ratio: refers to the amount of feed consumed by livestock and poultry per weight gain 1kg.
