New pig feed resources replace expensive raw material technology
In today's challenging swine market and the ongoing issue of swine diseases, making pig farming more cost-effective has become a top priority. One effective strategy to achieve this is by reducing feed costs. As traditional feed ingredients become increasingly expensive, exploring alternative feed sources has become essential.
New animal protein resources offer promising options. These unconventional protein sources include insects like black soldier flies, snails, and earthworms. In practice, larvae of the common housefly have already been used to partially replace fishmeal in pig feed. Similarly, silkworm pupae have shown potential as a substitute for fishmeal, with early results being encouraging. Silkworm pupae contain unknown growth-promoting factors that can enhance feed conversion rates, sow fertility, and embryo survival.
For energy feed resources, pigs—being omnivorous monogastric animals—cannot efficiently utilize high-fiber feeds like ruminants. However, by pre-digesting fibrous materials using microbial enzymes, these can be effectively incorporated into pig diets. Other feed ingredients such as oats, barley, and sunflower meal can also be utilized through similar processing methods.
When it comes to cereal crop substitutes, wheat, sorghum, and other grains have proven to be viable alternatives to corn. Wheat, for instance, has a higher protein content—10% to 17% more than corn. Broken rice and barley can replace up to 50% of corn without causing any adverse effects, while replacing 40% of corn with sorghum can yield even better results.
Industrial and agricultural by-products are often overlooked but hold great potential as livestock feed. Traditionally, meat meal, bone meal, blood meal, and soybean meal are commonly used. However, other materials such as leather powder, distillers’ dried grains, and fruit and vegetable waste are rarely utilized, despite their potential value.
Algae also present an interesting alternative. Found in rivers, oceans, lakes, and ponds, algae are rich in protein, containing about 50% protein by weight. They can be cultivated using wastewater from pig farms, then processed into a valuable protein source for pig feed.
Lastly, probiotic feed additives are gaining attention as a natural alternative to chemical additives. While chemical additives may accumulate in animal products and contribute to antibiotic resistance, probiotics offer a safer and more sustainable option. Their successful use in pig diets has opened new possibilities for improving pig performance, especially in cases where feed palatability is poor or stress levels are high. Studies have shown that adding probiotics can significantly enhance pig growth and productivity, offering substantial economic benefits.
