Types of additives used in pig farms at this stage and their effects
Pregnancy in sows is a critical phase that requires special attention to nutrition and health. Vitamins A, D, and E, along with minerals like calcium and phosphorus, are essential for the healthy development of piglets. These nutrients support strong bone growth, immune function, and overall vitality. Additionally, feed additives such as pepper can help reduce the incidence of diseases in piglets, while fats and oils increase milk production in sows, improving the survival rate of newborns.
Saccharin is often used to enhance the lactation performance of sows, ensuring they produce enough milk to nourish their litter. During the early growth period of piglets (from birth to 20 kg), it's important to focus on their nutritional needs. Saccharin can boost feed intake, while acidifiers help prevent diarrhea. Organic acids also play a key role in promoting healthy growth and increasing the survival rate of young pigs.
It’s crucial to note that during pregnancy and the early stages of piglet development, farmers should avoid using illegal or unregulated additives. Improper use of these substances can lead to serious consequences, such as miscarriage in sows or death in piglets, resulting in significant losses.
Once piglets exceed 20 kg, their diet should be adjusted to support rapid growth. Feed additives like lysine, fermented blood meal, and chlorpromazine can improve growth rates and strengthen disease resistance. Vitamins such as A, D, E, B-complex, and C are also vital for their development and overall well-being.
However, some additives come with risks. For example, arsenic compounds like Roxarsen are commonly used but can be harmful if overused. Excessive amounts may cause chronic poisoning and even liver cancer. Similarly, nitrite is used as a coloring agent in cured meats, but too much can lead to food poisoning and even death.
Preservatives like sorbic acid are safe when used within recommended levels, but exceeding them can harm kidney and liver function. Phosphates are used as water retention agents, but excessive intake may interfere with calcium absorption, leading to weak bones and fractures.
Other ingredients like gelatin, starch, and flavorings help improve texture, taste, and stability in meat products. However, overuse of certain additives, such as alkaloids, can irritate the digestive system and cause poisoning symptoms.
Clenbuterol, a banned substance in many countries, is sometimes used to increase lean meat percentage in pigs. Its residues in meat can cause severe health issues in humans, including heart palpitations, nausea, and even death in extreme cases.
Sedatives like barbital and hormones are also sometimes used to control pig behavior or promote faster growth. However, their residues in meat can lead to long-term health problems, including cognitive impairment and cardiovascular diseases.
Antibiotics, while useful for preventing infections, must be used responsibly. Overuse can lead to antibiotic resistance, which poses a major threat to public health. It’s important to follow guidelines and avoid unnecessary or excessive use.
In summary, proper nutrition and responsible use of feed additives are essential for the health of both sows and piglets. Farmers should prioritize quality feed and avoid harmful practices to ensure safe and sustainable livestock production.
