Adversidades e inovações no uso de gorduras na nutrição de ruminantes

The use of fats in ruminant feed has shown to be a promising practice to increase energy production and improve feed efficiency. However, the inclusion of fats in the diet of ruminants can bring some challenges and adversities. Fat supplementation can modify fermentation patterns in the rumen, affecting dry matter intake (DMI) and nutrient digestibility. The inclusion of fats in the diet can increase the production of methane and ammonia, which can be harmful to the environment and the health of the animals. The effects of fats on ruminant nutrition can vary significantly depending on the lipid source used and the experimental conditions. Fat supplementation can alter the fatty acid profile in milk, which can have implications for the quality of dairy products and consumer health. This review highlights the negative impacts of fat on rumen function. Despite these adversities, lipid supplementation is still a promising practice that can bring significant benefits if managed well.
