Which of the following strategies can lead to better nutrient digestibility in livestock?

Choosing diversified feed ingredients is a beneficial strategy for improving nutrient digestibility in livestock for several reasons. A varied diet can ensure that animals receive a broader spectrum of nutrients, which can enhance the overall digestibility of the feed. Different feedstuffs offer distinct profiles of amino acids, vitamins, and minerals; incorporating a mix can counterbalance potential deficiencies or imbalances found in any single ingredient.

Moreover, each feed ingredient has its unique digestibility characteristics. For example, fibrous feeds like hay may improve gut health and motility, while energy-rich grains can boost caloric intake. By offering a variety of ingredients, livestock can better utilize available nutrients, leading to improved growth rates and overall health.

In contrast, high moisture feeds can promote a risk of spoilage and mold, which may adversely affect nutrient availability and animal health. Reduced protein levels might lead to insufficient nutrient intake, particularly in growth or lactation phases where protein needs are elevated. Lastly, minimizing feeding frequency can lead to fluctuations in energy and nutrient intake, which may hinder the animals’ ability to digest and absorb nutrients effectively. Thus, diversified feed ingredients are the best option for enhancing nutrient digestibility.
