1. It's important to control the amount of fat added, not necessarily adding as much as possible. Young animals should receive a more appropriate amount, while in the later stages, pigs and poultry should be given less. Modern high-yield breeds typically require more fat, whereas local breeds may need less. For grain-based diets, it can be challenging to meet the energy demands of high-producing pigs, so adding fat becomes essential. To ensure optimal results, it's recommended that each farm conduct small-scale trials and adjust the fat content based on the outcomes of these tests.
2. Ensuring the quality of the fat is crucial. The oil should have no off-odors or signs of contamination. It must be free from doping, oxidation, denaturation, mold, toxins, or any other impurities. Adding the right amount of antioxidants is necessary to prevent rancidity. Commonly used antioxidants include BHT (butylated hydroxytoluene) and BHA (butylated hydroxyanisole), often used together at concentrations of 0.005% to 0.02%. However, ethoxyquin should be avoided because it tends to evaporate before oxidation occurs, making it ineffective for long-term preservation.
3. Pay attention to the overall energy balance when adding fats and oils. Increasing the supply of protein and amino acids is necessary to avoid deficiencies caused by the addition of fat. This helps maintain a balanced diet and supports healthy growth and development in animals.
4. After introducing fat into the feed, it's essential to increase the levels of vitamin B12 and vitamin C. These vitamins play a key role in the absorption and utilization of fat, which in turn improves the overall efficiency of the feed and enhances animal performance. Regular monitoring and adjustments are recommended to maintain optimal nutritional balance.
By carefully managing fat inclusion, maintaining quality standards, and balancing nutrients, farmers can significantly improve feed efficiency and animal productivity. Always consult with a nutritionist or feed expert to tailor the formulation to the specific needs of your livestock.
