Daily gain table of pigs at each stage

At the stage of body weight 24-50 kg, the average daily gain was 680 g, with a total consumption of 51 kg for piglets, 830 g for average daily gain at 50-75 kg, with a total consumption of 74 kg for medium pigs, and 930 g for 75-110 kg. A total of 110 kg of pig feed was consumed.

First, the feed quantity of pigs at each stage

1. Take the pig farm of 30 sows as an example, the daily feed quantity of each stage is as follows. When the pig farm starts operation, the daily reserve sow feed 72kg is about. After entering the actual litter stage, there are only 6 reserve sows, and the daily reserve sow feed 15kg is about.

2. The daily feed for breeding boars is about 8kg (whichever is about 2).

3. The daily feed 40kg of lactating sows is about 8, and the period is about 30 days / batch.

4. Need to teach the trough material 2.5kg every day (about 80 heads, the period is about 30 days / batch, that is, from 7-38 days old, the weight is about 2kg-12kg).

5. 50kg is needed every day (60 heads, 22 days / batch). That is, 38-60 days old, the weight is about 12kg-24kg), generally from the 28-day-old weaning began to mix with the teaching trough material.

6. The daily feed requirement for piglets is about 110kg (about 110heads, the cycle is about 40 days / batch, that is, from 60 to 100days old, and the body weight is about 24kg-50kg).

7. The daily need for medium pig feed 190kg is about 80 pigs, the cycle is about 30 days / batch, that is, from 100 to 130 days old, the body weight is about 50kg-75kg).

8. The daily feed 280kg of big pigs is about 105.The period is about 38 days / batch, that is, from 130d to 168d, the weight is about 75kg-110kg).

9. Daily feed 50kg for pregnant sows is about 20 (whichever is about 20).

Second, the daily weight gain of pigs at each stage

1. According to the rough estimate above, it can be used as the reference data in production, and the number of pigs in each stage of actual production shall prevail. For example, when breeding pigs were first introduced, there were only backup sows and breeding boars, but not small, medium, large pigs, pregnant sows, lactating sows and so on.

2. The consumption of teaching trough material during lactation period is about 500g, from 28-38 days old to weaning period, during this period, it is fed with mixed nursery material. During this 10-day weaning period, about 3kg / head and 3kg / head of conservation feed are consumed. Then from 38 to 60 days old as the conservation stage, feeding with conservation feed as feed, the consumption of conservation material at this stage is about 20kg/ head.

3. From the above data, it is known that from the beginning of feeding to the conversion of piglet feed to the age of 7-60 days, the total consumption of trough feed 3.5kg in piglet stage, and suckling pig feed is conservation 23kg.

4. From 60 to 100 days of age (body weight 24-50kg, average daily gain 680g), piglets consumed a total of feed 51kg, and the ratio of feed to meat at this stage was 1.96VR.

5. Middle pigs consumed a total of medium pig feed 74kg from 100 to 130 days of age (body weight 50-75kg, average daily gain 830g), and the ratio of feed to meat at this stage was 2.95v1.

6. From 130 to 168 days of age (body weight 75-110kg, average daily gain 930g), pigs consumed a total of feed 110kg, and the ratio of feed to meat in the stage was 3.1415.
