肉兔高效育肥方案：强度育肥与限制饲喂对比研究

Meat rabbit fattening is the final critical stage of commercial rabbit production. Fattening management directly determines market weight, carcass quality, and farming profitability. Scientific fattening plans should balance growth rate and meat quality.

Intensive finishing uses ad libitum feeding with high-energy high-protein complete pellets (DE 11 MJ/kg, CP 17%), starting 2 weeks post-weaning until reaching 2.5-2.8 kg for market. Advantages include high daily gain (35-40 g) and short finishing period (45-55 days), but feed costs are high and abdominal fat deposition tends to be greater.

Restricted feeding controls daily intake at 80-90% of ad libitum, with daily gain of 30-35 g, but feed conversion ratio improves by 5-8% and abdominal fat is reduced. Suitable for premium rabbit meat markets with higher prices.

The compromise is a phased fattening strategy: early phase (weaning to 1.8 kg) uses moderate restriction for frame development; late phase (1.8 kg to market) uses intensive finishing for weight gain. This approach combines advantages of both models with optimal overall returns.

Key fattening management parameters: 3-4 rabbits per cage, temperature 18-22 degrees Celsius, 12 hours lighting. Stop all medication in feed 7 days before marketing; strictly observe withdrawal periods. Fast 8-12 hours before transport but not water-deprived, to reduce transit losses.
