In modern pig farming, the focus is often on the nutritional content of feed per kilogram, while the actual daily feed quantity is frequently overlooked. Even if breeders formulate feed precisely according to the required nutritional levels, the total amount provided might not meet or exceed the nutrients needed for optimal growth, leading to extended feeding periods, reduced feed efficiency, or even overeating and digestive issues. These problems can result in wasted feed. Therefore, scientific feeding practices must be emphasized alongside proper feed formulation to maximize feed utilization.
For finishing pigs, the typical daily feed amount is around 4% of their body weight. For lean pigs weighing over 60 kg, it’s generally recommended to provide about 3.5% of their body weight in feed. Alternatively, the daily feed amount can be calculated based on expected daily weight gain and feed conversion rate using the formula: daily weight gain (kg) × feed conversion rate (feed/gain) = daily feed amount (kg).
Moderate feeding is essential, following the natural growth pattern of pigs—faster growth during the middle phase and slower growth later on. To achieve a better feed conversion rate, a straight-line fattening approach is recommended to shorten the feeding period and save feed. Additionally, mixing fine, green, and coarse feeds, along with using raw mixed feeds, can improve digestion and nutrient absorption. Feeding twice a day helps reduce energy expenditure and minimize feed loss caused by frequent movement stimulated by multiple feedings.
Maintaining an appropriate temperature in the pigpen is also crucial. The environment should be clean, dry, cool in winter, and well-ventilated in summer to create ideal conditions for pig growth, reduce disease risk, and enhance feed efficiency. The optimal temperature range is between 17°C and 21°C.
Disease prevention plays a key role in efficient feeding. Effective pest control and regular deworming are necessary to minimize the impact of chronic diseases and parasites, which can cause hidden feed waste. Vaccinations and scheduled deworming should be part of a comprehensive health management plan to ensure pigs grow healthy and efficiently.
Finally, timely slaughter is important. Pigs have different growth patterns at various stages: bones and lean meat develop faster before 60 kg, while fat accumulates more as they age. The feed required to produce 1 kg of fat is significantly higher than that needed for 1 kg of lean meat. Thus, the longer the feeding period and the heavier the weight, the lower the feed efficiency. For most hybrid pigs, the ideal slaughter weight is between 90–100 kg, while native breeds are typically slaughtered at around 85 kg, and less developed or uncultivated breeds at about 75 kg.
