The formula for chicken feeding is as follows:
First, the laying hens (grams of raw materials per chicken)
Before 10 days of age: for age +2. For chickens of 8 days old, the daily feed amount chicken is: 8+2=10 (g)
20--50 days old: equal to the age of the day. For chicks of 30 days old, the daily feed amount per chicken is 30 (grams).
51-150 days old: 50+ (days - 50) ÷ 2. For example, 100-day-old young chickens use 50+ (100-50) ÷ 2 = 75 (g)
The broiler chickens of 150 days old or older can be stabilized to more than 100 grams, and the daily feed amount of chickens at the peak of egg production is about 120 grams.
According to the above calculation method, a hen consumes 8.84 kg of accumulated material at 150 days of age, and the feed amount of the laying hen is 36.5 kg per year, which can basically meet the needs of laying eggs and avoid waste.
Second, fast large broiler chicken (based on Ross 308) (feeding per chicken, gram)
Before 10 days of age: daily feed intake increased by 4 grams per day. For example, 7-day chicks eat 28 grams per day.
11-20 days old: (day age -2) ÷ 10 × 50 (g). Such as: 15 days old, (15-2) ÷ 10 × 50 = 65 (g).
21-30 days old: (day age -1) ÷ 10 × 50 (g). Such as: 26 days old, (26-1) ÷ 10 × 50 = 125 (g).
30-40 days old: age ÷ 10 × 50 (g). Such as: 35 days old, 35 ÷ 10 × 50 = 175 (g).
After 40 days of age: basically maintained to 200 grams until the stall.
The above is the daily intake of broiler chicken per day. Under normal circumstances, feeding with full-price materials, each chicken will eat 4.5 kg of food, and the weight can reach 2.5 kg. In normal breeding, the flock should not exceed the feed intake of the day. If it is considered that the flock is not normal, the feed intake should be appropriately restricted during the feeding and management process. Otherwise, the flock is easy to be affected or difficult to control after the onset.
Third, meat mixed chicken
Daily feed intake (g) = age × ×
Fourth, pig:
Weight stage:
11-30kg daily feed intake 800g or so
30-70kg daily feed intake of 2000g or so
70-110kg daily feed intake 3000g or so
Can also be calculated according to the weight of the pig: feed intake (g) = actual weight (kg) x coefficient
The coefficient is: piglet 0.05; medium pig 0.04; big pig 0.03
Such as: 35d pig weight is about 10kg, then the feeding amount (g) = 10000x0.05 = 500g
(1) 7-50 days from the start of feeding to the use of piglets, the total consumption of 5.8kg of teaching materials, 15.28kg of suckling pigs;
(2) The piglet consumes 35.65kg of piglet feed from 50d-87d (15-35kg);
(3) Chinese pigs consume 80.8kg of feed from 87d-125d (35-65kg)
(4) Large pigs consume 118.8kg of feed from 125d-168d (65-108kg)
