For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early ...
The nutritional quality of feed is influenced not only by the nutrient content, but also by many other factors such as feed presentation, hygiene, digestibility, and effect on intestinal health. [17] Feed additives provide a mechanism through which these nutrient deficiencies can be resolved, improving animal rate of growth, health, and well ...
Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins or nutrients their bodies cannot otherwise synthesize. Animals generally have a higher requirement of energy in comparison to plants. [25]
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons.
Complete rations feature the blended approach; all forages, concentrates, protein supplements, minerals and vitamins are mixed and offered as a single feed. Complete-ration systems can save labour and reduce overall feeding costs. It is extremely important to keep the mixture exactly the same day after day and to make big changes gradually.
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, management, production, nutrition, selective breeding , and the raising of livestock .
Many animals regularly visit mineral licks to consume clay, supplementing their diet with nutrients and minerals. In tropical bats, lick visitation is associated with a diet based on wild figs (), which have very low levels of sodium, [3] [4] and licks are mostly used by females that are pregnant or lactating.
All animals are chemoheterotrophs (meaning they oxidize chemical compounds as a source of energy and carbon), as are fungi, protozoa, and some bacteria. The important differentiation amongst this group is that chemoorganotrophs oxidize only organic compounds while chemolithotrophs instead use oxidation of inorganic compounds as a source of energy.
