Title:A Review: Comparison between Grazing Behavior of Cattle and Sheep Authors: Nima Mosavat; Mohammad Chamani DOI: Aff: Department of Animal Science, Behbahan Branch, Islamic Azad University, Behbahan, Iran Author Email: Keywords: Behavior Grazing; Bite Mass; Bite Rate; Browsing; Sheep; Cattle URLs:ABSTRACT-HTML | FULLTEXT-PDF | Abstract:The aim of this study was to investigate the behavior of cattle and sheep grazing and expression of behavioral differences between cattle and sheep is because, to thereby allow grazing management strategies amid animal feed. Grazing circumstances, the daily consumption and duration is grazing, it can result from consumption of feed bite mass (mass and carved teeth) and tooth cutting (bite rate) Fodder, and the duration of time since eating and eating meals to consider. All herbivores digest and ability to deal with toxins are not equal. Food animals that is physiologically adapted to digest it and those that will meet their nutritional needs, taking. Since these differences are inherited in the diet, vegetarians often have been classified into three major groups: grazing, browsing, and the intermediate feeders. Cattle feed off your tongue and pulls it into the mouth. The feed between the upper and lower molars and pre-molars or the lower jaw and upper jaw tooth pad covers. Feed the plants with a backward jerk off to her. With a wide mouth and lips uncompromising high, large clumps of grass cattle can catch in your mouth. The method of choice is to eat a cow, resulting in more dead material from other ruminants, such as sheep, goats and deer, the narrower the mouth and lips are flexible, eats. The mouth parts of cattle selected for leaves of woody plants (twigs breaking) is more difficult. There is strong evidence that the diet of ruminants has clear priorities, a change in the physiological state of change, and that seems to be an evolutionary basis. Rather than ignore these evolutionary traits, we should strive to consider when designing systems for animal management. Since animals and parts of plants (green leaves) or choose a particular plant species, total plant material available at present can not be considered for grazing animals. Sheep and cattle grazing behavior by various factors, seasonal and circadian patterns, temperature and humidity, wind direction, race, access to water, topography, availability of pasture, elimination (defecation), social structure and social facilitation affect be.
