When doing cattle fattening, you need a lot of chicken litter, so I always keep broilers to help produce it. I just finished with the vet. Remember the cattle I bought for pen fattening? Among them were 6 cows that an experienced farmer encouraged me to buy because they had big frames and only needed to be pen-fed for 45 days. They weighed an average of 300kg, and I paid about $500 for each. So far, they have added about 65kg. If I slaughter one now, I will get about 210kg of meat, which I will sell for $5 per kg and get $1050. If I add the offals, head, and mazondo, that's another $100, bringing it to $1150. The $50 will remain at the abattoir, so I will have $1100. If you have a butcher, you can sell for even up to $7 or $8 per kg, depending on the grade. But now, after the vet visited, 4 of the 6 cows are pregnant. That's good news for another farmer but bad for me, because pen fattening is more profitable than waiting for a year uchikama mukaka, only to end up with another mombe worth $500. I hope you get the maths.
