Best slaughter period for meat animals

Meat livestock includes various animals such as pigs, cattle, dogs, broilers, ducks, and rabbits. Each species has an optimal time for slaughter that maximizes meat quality, feed efficiency, and economic returns. Understanding these periods is essential for farmers and breeders to ensure profitability and high-quality products. Pigs experience a growth pattern where weight gain starts slowly, accelerates during the middle phase, and then slows down again in later stages. Typically, when pigs reach around 100 kg, their growth plateaus. Beyond 150 kg, weight gain becomes minimal. Slaughtering too early can result in low carcass yield and poor meat quality, while slaughtering too late leads to higher feed costs and lower efficiency. In China, local pig breeds are best slaughtered at about 75 kg, offering the best balance of meat quality and yield. Crossbred pigs, such as those from local sows and lean meat bulls, are ideal for slaughter at 7–8 months of age, weighing between 90–100 kg. For cattle, the Charolais crossbreed shows a decrease in daily weight gain from 1.19 kg to 1.12 kg between birth and six months, and further drops to 0.91 kg between July and December. Calves grow fastest in their first 6–8 months, after which muscle growth slows, and feed efficiency declines. Therefore, beef cattle are best slaughtered at 1.5 to 2 years of age, when economic returns are highest. Sheep and goats follow seasonal patterns, with lambs gaining the most weight in September, reaching around 40 kg for sheep and 25 kg for goats. The ideal slaughter period is at the end of September or early October. To meet holiday market demands, supplementary feeding ensures better meat quality, allowing for higher prices during January and February. Meat dogs were traditionally raised for 8 months before slaughter, but this often led to poor economic returns. Modern breeding practices have improved efficiency, with many dogs reaching 20 kg by 4 months of age. At this stage, they grow quickly, use feed efficiently, and produce high-quality meat. Overfeeding reduces profitability, so timing is key. Broiler chickens grow rapidly in the early weeks, with hens peaking at 7 weeks and roosters at 9 weeks. Delaying slaughter increases feed costs and fat content, reducing meat quality. While some chickens may reach market weight at 6 weeks, their meat quality is suboptimal. The ideal time for slaughter is 6–7 weeks, weighing 1.9–2 kg, ensuring good feed conversion and consumer satisfaction. Ducks are usually marketed at 7 weeks, weighing 2.5 kg. For cut meat or export, they should be slaughtered at 8 weeks when the breast muscles are well-developed. The timing depends on the market, but all meat ducks must be at least 8 weeks old before slaughter. Rabbits are best slaughtered at 3 months of age, weighing 2–2.5 kg. Keeping them longer reduces annual production and affects meat quality. Proper timing ensures the best results for both productivity and meat quality.
