demand any nonfarmer what setscowsapart from homo , and they ’ll probably rattle off a list that includes four legs , an udder and a tail . One underlie conflict that ’s most canonic to bovine physiology is that cows have a ruminant digestive system . Joining them among the ruminant ranks aresheep , goats , bison , deer , elk and caribou .
Ruminant creature have a four - compartment venter ( rumen , second stomach , third stomach and abomasum ) , each doing its part to break down fibrous materials more efficiently than creature with simpler digestive systems . Rumen germ produce cellulase enzymes , which break down industrial plant textile into volatile fat dose to be absorbed by the animal to practice as free energy , into ammonia that is used to make microbial protein — the animal ’s master protein root — and into gasses . As the intellectual nourishment particles carry on through the stomach compartments , other nutrient are absorb .
There ’s no one - size - fit - all plan for feeding ruminant , even those of the same mintage , because nutritional needs are affected by many factors , including maturation , pregnancy , lactation , fibre production , natural process and environment . The germ in the ruminant digestive organization can stand and take in nutrition from even hapless - caliber foraging , but that does n’t mean ruminant should n’t be feed the good forage available .
Pasture is often the most stinting provender for ruminants and can be mellow in vim and protein during the botany ’s growth stages . As grasses , browse and forbs mature , they become less digestible , so pastures should be rotated regularly for the swell nutritional benefit . Hay and silage are substitute when grazing land is not available , and their nutritive character varies greatly based on the fields where they were reap , the conditions under which they were reap and their computer memory environs . dressed ore feeds — grains and animal or plant byproducts , such as soybean repast or Pisces repast — be given to be either gamy in Energy Department or high in protein and can sate in nutritional gaps where forage leaves off . Ruminant microbes have no problem digesting unrefined grains ( for model , oats that are not wind or corn that is not pinch ) .
To keep a ruminant animate being healthy , the microbes must be kept healthy . Fast changes in diet importantly untune the microbial population . For model , if grass - fed sheep are dead changed to a grain - found diet , their digestive microbes will all be suited to forage digestion and will be unable to divulge down the grain . The use ofantibioticscan also upset the microbial universe .
Ruminants do many purposes on the little farm , including as sources of meat , milk , draught power andfiber . Because unlike specie prefer tograzedifferent types of forage , get a form of ruminant beast can benefit pasture health in a rotational - graze management system . Cattle and sheep prefer grasses over legumes , whereas goats favor forbs and browse ; so as part of a revolution programme , a premix of these species can keep apasturegrazed down and producing well .
