Diet change on ages
Wagyu beef is tender and contains various nutrients such as essential fatty acids, essential amino acids, iron and B vitamins. When raising Wagyu cattle, the work is usually divided between breeding and fattening farmers. Breeding farmer is raising the mother cows and give birth and raise calves for about 9 months to get the calves ready for market.
The average calves raised at fattening farm weighs about 300 kilograms (approx. 660lb), so they need a lot of food. The feed at the first stage is called roughage, which is mainly rice straw and hay, and the amount is from 2 kg to 5 kg per day. The feed is set at 2.5 kg and the stomach is gradually enlarged. At 12 months of age, that is, in the third month of fattening, the feed mix is gradually increased to 5.5 kg/day. The weight range is from 5kg to 8kg. At this time of the year, the rice straw is mixed with the compound feed.
At 15 months of age and six months of fattening, the cattle should be fed a large amount of formula feed. This is very important period for wagyu cattle and cattle that are well fed on formula feed at 6 months of age will become fine marbled cow. At 19 months of fattening, she will change from a round belly to a square, boxy belly, but she is not in good shape. But on the contrary, it is a sign that the quality is getting better. At 21 months of fattening, the cattle weigh 800kg. The Japanese Wagyu cattle are shipped at 30 months of age.
