    Bayley, H. The generalstrategy adopted by horses is to ingest relatively more forages than ruminants, especiallyhigh fiber foods. Horning, E. Domestication of horses probably occurred around to BC by nomads insouth Russia and at that time nutrition of horses did not change much from the naturalenvironment. Lange, J. When analyzing forage only the most adequate predictor ofdigestibility is crude protein, although crude fiber also has significance.

    Vitti, D. These hormones then diffuse to nearby target cells. A deficiency of this mineral has been linked to impaired RNA and DNA production, decreased testosterone production and poor sperm motility. Salmon, R.

    Dairy Sci. If glucose levels are too high, the pancreas secretes insulin to lower glucose levels. Horses showedphysiologic adaptation to winter starvation. Saliva assists with swallowing. Glucose Metabolism in the Rumen The carbohydrate com-ponents in ruminant diets are mainlyhexose polymers like cellulose, starch,fructans, and pentose polymers, mostlyxylan; Walker, ; Martin,

Hormones and metabolism in ruminants book

Sperm production and function is often associated with zinc. Academic Press. Scientific paperson digestive physiology, protein and energy metabolism were only published in the 19thcentury. Pohlenz, S. Biographical SketchDr Tanja M. Enabling nutrients to bypass the rumen will increase the utilization of feed for production, and also create a more adequate supply of amino acids.

Unlike fatty acids, the released glucose can provide energy in the absence of oxygen and can thus supply energy for anaerobic activity. What is more, the use of hormonally-active substances in the future may not be limited to those currently available.

Equids in free ranging situations also actively select higher quality diets than cattle. Little, W. When oxygen levels are too low, the kidneys produce and release a hormone called erythropoietin EPO. The ability to digestdifferent feedstuffs brought the disadvantage of the horse having a less efficient for theuse of plant fibers.

Sneddon J. Journal of Animal Science 60, Dinius, D. Most of non-ruminantherbivores rely on the hindgut as primary site of fermentation.

Peptide Hormones These protein hormones are composed of amino acids. Animal Factors4. IntroductionHerbivores are animals vertebrates or invertebrates that can subsist on a diet consistingprimarily of fibrous plant material.

In equids the feed is partially digested in the stomach and small intestine before it issubjected to microbial fermentation in the hindgut.

Journal of Animal Science 67, This conversion takes place mainly in the liver and to a lesser extent in the intestines and kidneys. The fragmenta- starch digestion in the rumen, there being pH Mould and Orskov, ; Mould ettion by alpha-amylase initially leads to a less starch available for fermentation in al.

Some other views argue that cattledigests better all components in grasses, with the exception of protein and nitrogen—freeextract, which is similar between the two species.

In horses, food must be present inthe mouth for saliva to flow. Feeding Habits Comparing Equids to RuminantsEquids can be classified as generalist herbivores that co-exist with bovids in guilds ofgrazing herbivores in tropical ecosystems like in Africa.
