one method of obtaining cattle breeds
Answers
The farmer feeds all the cows and one bull on 15 hectares. The steers are fed until they reach 250 kg carcass weight.
Such a farmer would be feeding 5 cows and one bull.
If the calving percentage is 80%, 4 calves, 2 heifers and 2 bulls, will be born each year.
The farmer sells the two heifers at weaning, when they are 8 months old. In order for a steer to reach a carcass weight of 250 kg, it takes 4 years on the kind of pasture we are using.
So 6 steers over one year old will also be in the paddock Every year the farmer sells:
2 steers, each with a carcass weight of 250 kg. If the price is 120 vt/kg carcass weight, the farmer will get:
· 120 vt x 250 x 2 = 60,000 vt.
2 weaned heifers 8 months old, with a live weight of about 140 kg. At 60 vt/kg live weight, the farmer will get:
· 60 Vt x 140 x 2 = 16,400 Vt.
Total earnings every year are 76,400 vt. Every two years the farmer has to keep one of the heifers to replace a cow which should be sold. The price for an old cow is about the same as the price for t
METHOD 1 - Breed and feed the calves until they grow big.
The farmer feeds all the cows and one bull on 15 hectares. The steers are fed until they reach 250 kg carcass weight.
Such a farmer would be feeding 5 cows and one bull.
If the calving percentage is 80%, 4 calves, 2 heifers and 2 bulls, will be born each year.
The farmer sells the two heifers at weaning, when they are 8 months old. In order for a steer to reach a carcass weight of 250 kg, it takes 4 years on the kind of pasture we are using.
METHOD 2 - Breed and sell all the weaners.
This farmer runs cows and one bull, but sells every calf at weaning time, or at about 8 months old.
This means one bull and 12 cows are run on the property.
If his calving rate is 80%, 10 calves will be obtained every year.
The farmer must hold on to one heifer every year to replace an old cow. when the heifers are ready to bear calves, an old cow can be sold. The price for an old culled cow of about 160 kg carcass weight is about the same as for a weaner heifer.
METHOD 3 - Buy young steers and fasten them.
This way, the farmer doesn't have any cows or a bull. Weaner steers (steers which are 8 months to I year old), are bought.
Afterwards, they are fed until they reach a carcass weight of 250 kg. This means the farmer must feed the steers for another 3 years, until the steers are nearly 4 years old.
So, the farmer buys 15 young steers 8 months to one year old every three years. Using this method, the farmer might buy 5 young ones and sell 5 old ones every year; it doesn't mean they must all be bought and sold at the same time.
