Secret Book of breeding-Summary of formulas for calculating Poultry Feed intake

Mixed Meat Chicken:

Add 2.5 grams per day from day one. That is, the feed intake of 1000 817 meat hybrid chickens on the 35th day of age is:

2.5g× 35d ×1000 pcs/500g =175 kg

[Simplified as: age × number of animals <$200 =? Jin]

Big Meat: (Simple)

Feed intake was twice that of 817 broilers, increasing by 5 grams per day from day one. That is, the feed intake of 1000 white feather broilers on the 35th day of age is:

2.5g×2× 35d ×1000 pcs/500g =350 kg

[Simplified as: age × number of animals ÷100=? Jin]

(Details)

Fast Large Broilers (based on Ross 308)(Daily Feed Intake per Chicken, g)

Before 10 days of age: Daily intake increased by 4 grams per day. For example, 7-day-old chickens eat 28 grams per day.

11-20 Age: (age-2)<$10 ×50(g). For example: 15 days old,(15-2)<$10 ×50=65 g.

21-30 Age: (age-1)<$10 ×50(g). For example: 26 days old,(26-1)<$10 ×50=125 g.

30-40 Age: Age <$10 ×50(g). For example: 35 days old, 35 divided 10×50=175 (g).

After 40 days of age: basically maintain to 200 grams, until the market.

The above is the daily feed intake per chicken for broilers. Under normal circumstances, with complete feed feeding, each chicken to the slaughter eat a total of 4.5 kg, the average weight can reach 2.5 kg. In normal breeding, the chicken flock should not exceed the feed intake of the day. If it exceeds the feed intake, it is considered that the chicken flock is abnormal. In the process of feeding and management, it is necessary to appropriately limit the feed intake, otherwise the chicken flock will be easy to develop disease or difficult to control after the disease.

Mixed meat chicken

Daily feed intake (g)= age ×2.2

Layer:

Feed intake per chicken per day is: (unit: g)

1~10 days, age +2;

10~20 days, age +1;

20~50 days, the number of days;

50 - 120 days,(age +50) divided by 2;

After 120 days of age, the daily feed intake was maintained between 100 and 120g.

That is, the feed intake of 1000 laying hens on the 35th day of age is:

35 d×1000 pcs/500 g =70 kg

Now the actual harvest of the variety is slightly lower than the formula

According to the above calculation method, the accumulative feed consumption of a hen to 150 days of age is 8.84 kg, and the annual feed consumption of laying hens is 36.5 kg, which can basically meet the needs of laying eggs and avoid waste.

Meat duck:

Within 12 days of age---12× number of days × number of animals/1000= daily feed intake (kg)

12-18 Age----15× age × number/1000= daily feed intake (kg)

After 18 days of age--18× number of days × number of animals/1000= daily feed intake (kg)

Egg duck:

2.5g on the first day and 2.5g daily thereafter;

The feed intake of each bird was 125g per day until 50 days of age, and about 150g after 90 days of age.

Take 1000 for 50 days.

Formula: 2.5g× 50d ×1000 pcs/500g/kg =250 (kg)

Broiler breeder:

36g at the end of three weeks, and then increase 2~ 3 g per week. Feeding restriction shall be carried out according to the specific conditions of chicken farm and chicken flock after opening and delivery.

Formula for calculating feed intake of other poultry

Green-legged chicken, fast three-yellow chicken:

Refer to 817 formula for calculation of daily intake of meat impurities.

Mansanhuang: refer to the formula for calculating daily feed intake of laying hens

Goose: Reference meat duck, but not very accurate, goose has coarse grain.

It is stated here that the daily feed intake calculation formula of these poultry is only for reference. The actual feed intake of poultry below 20 days old should be slightly less than that set out in the formula, and the actual feed intake of poultry above 30 days old should be slightly more than that set out in the formula. Technicians should analyze according to the type of poultry and feeding situation.
