88 88 Aid in the absorption of fat-soluble vitamins, which are vital for the bird’s immune function and health. Play a protective role for the liver by reducing the risk of fatty liver syndrome. Provides a concentrated source of energy, which is essential for maintaining high egg production and overall bird health. For reference, fats provide about 9 calories per gram, which is more than double the energy provided by carbohydrates or proteins, each of which provide about 4 calories per gram. Improve the palatability of the feed, encouraging better feed intake. FAT & OIL IT IS RECOMMENDED . . . . . . to include at least 1–2% of fats or oils in the diet of laying hens. This inclusion becomes even more important during periods of heat stress, as fats provide a more efficient energy source compared to carbohydrates, helping to maintain energy levels and reduce metabolic heat production in birds. Storage Conditions Store fats and oils in cool, dark, and dry conditions to minimise exposure to air, light, and high temperatures, which can accelerate oxidation. Use of Antioxidants Add antioxidants to fats and oils to prevent oxidation. Antioxidants help maintain the quality and nutritional value of fats and oils by inhibiting the formation of free radicals and peroxides. Regular Quality Checks Conduct regular quality checks to monitor the levels of oxidation and ensure that the fats and oils remain within acceptable limits. This includes testing for peroxide values and free fatty acid levels. Proper Handling Handle fats and oils carefully to avoid contamination and degradation. Use clean and appropriate containers and equipment to prevent exposure to contaminants. Rotation of Stock It is crucial to regularly rotate stock to ensure that older fats and oils are used first, thereby reducing the risk of using degraded or oxidised products. This practice is especially important during the summer, when high temperatures can accelerate the oxidation and degradation of fats and oils, compromising their quality and nutritional value.
