Cost and profit of Rex rabbit breeding

American Rex rabbit is a kind of precious fur animal introduced from the United States, which is mainly used as leather and is a high-grade leather raw material. Meat is rich in nutrients. Raising Rex rabbit is a new and efficient industry. It can reproduce rapidly, and a female rabbit can reproduce five to six litters a year, with an average survival of 6 rabbits per litter, each group (1 male and 3 females). If counted according to 5 litters, 90 commercial Rex rabbits (over 5.0 jin) can be produced annually (i.e. 6 × 5 × 3 × 90). Note: the following data are all theoretical data and may be different from the actual breeding cost.

Cost of breeding rabbit

1. Feeding fee: each rabbit needs about 70 jin of mixed concentrate per year, which is calculated at 0.7 yuan per jin, which costs only 49 yuan a year, and 49 × 4 yuan 196 yuan for a group.

2. The cost of epidemic prevention and medicine: 2 yuan for each, and 2 × 480 yuan for one group.

3. Depreciation sharing fee for breeding rabbits: calculated according to the use of three years, if a group of rabbits is calculated at 600 yuan, it can recover 50 yuan × 4 million 200 yuan after three years, and the actual loss is 600-200 yuan 500 yuan, divided by 3 (years), that is, 166 yuan per year.

4. The total cost is 196 + 8 + 166-362 yuan.

Commodity rabbit cost

Each commercial rabbit needs 25 jin of concentrate (about 150 days) to raise more than 5.0 jin, which is 0.7 yuan per jin, that is, 0.7 × 25 yuan 17.5 yuan, 1 yuan for epidemic prevention and medicine, and 18.5 yuan for each. Each group 3 (female rabbits) × 30 (breeding number per female rabbit) × 18.5yuan (cost per rabbit) = 90 × 18.5yuan = 1665 yuan.

Each group of benefits

1. Gross profit; calculated according to the average price in recent years, that is, live rabbits weighing more than 5.0jin are about 6-10 yuan per jin, and 30 live rabbits are sold annually, each weighing 5.0jin, with an average of 8 yuan per catty, that is, 30 × 5.0jin × 3 (female rabbits per group) × 8 yuan = 3600 yuan.

2. Net profit: gross profit-breeding rabbit cost-commodity rabbit cost: 3600 yuan-362yuan-1665 yuan = 1573 yuan.
