Background technology
The milk cattle cultivating mode of high-energy, intensification has improved the production efficiency of animal greatly at present, but has also caused a series of metabolic disease simultaneously, is restricting the further lifting of animal production efficiency and animal product quality.Acute or subacute cud acidosis is the common metabolic disease during milk cow produces; It is the not normal performance of function of rumen; Can cause that the ruminal digestion rate reduces, DMI reduces, and a series of metabolic disease such as laminitis; Influence productivity, cause animal dead (Gozho et al.2007 when serious; Nocek 1997).Allen (1997) thinks that rumen ph is that fermentation acid produces in the cud, removes the result of three's balance by the saliva neutralization and from cud.The generation of lumen fermentation acid is mainly determined by the daily ration fermentation character; Remove from cud and to refer to animal cud wall and get into the downstream digestive tract to acidic absorption with through the ruminal digestion thing, mainly the physical characteristic by animal physiological characteristic and feed determines; The saliva neutralization depends primarily on saliva production, by the physical characteristic decision of daily ration.
Ruminant chews activity, is the important indicator (Mertens 1997) that characterizes animal cud health status.Ruminant can chew activity through stimulation, increases saliva production, and it is stable to keep rumen ph, avoids a series of metabolic diseases such as cud acidosis.The ability of chewing of ruminant is with searching for food, ruminate or the time of chewing being represented (Beauchemin et al.2003; Yang and Beauchemin, 2007).
In the current research, adopt the artificial observation method to measure the ability of chewing of milk cow, concrete grammar does, regulation is not searched for food in the 20min after searching for food last time and stopping again, and thinking searches for food stops; After ruminating last time, do not ruminate again in the 5min, think to ruminate to stop, writing down the time (Krause and Combs 2003) of searching for food and ruminating respectively.The time of chewing is with time of searching for food+ruminate time representation.
The index observing method is artificial numeration, does not have repeatability, can not carry out rechecking, maybe be because different observer or other accidentalia causes bigger, irremediable error to result of the test; Index determining is a mensuration cycle with 24h generally, and workload is big, and a people is difficult for accomplishing; And accomplish by different people, the difference of yardstick is prone to cause error between different observations.
