Aspects of Ingestive Behavior in Cattle 1'2
Ingestive behavior in cattle differs from other species because of physiological mechaniSms developed pari passu with fermentative digestion. The secondary refection of rumination allows remastication and reinsalivation of the lane bulk of vegetable food ingested. The need to buffer acid products of cellulose digestion demands continuous high secretion of alkaline saliva. Nervous and hormonal s...
متن کاملNeuroendocrine regulation of appetitive ingestive behavior
Food availability in nature is often irregular, and famine is commonplace. Increased motivation to engage in ingestive behaviors increases the chance of survival, providing additional potential opportunities for reproduction. Because of the advantages conferred by entraining ingestive behavior to environmental conditions, neuroendocrine mechanisms regulating the motivation to acquire and ingest...
متن کاملDevelopment of ingestive behavior.
Swallowing represents a primary physiological function that provides for the ingestion of food and fluid. In precocial species, swallowing activity likely develops in utero to provide for a functional system during the neonatal period. The chronically instrumented ovine fetal preparation has provided the opportunity for recent advances in understanding the regulation of in utero swallowing acti...
متن کاملThe control of ingestive behavior by the median raphe nucleus.
For a period of 20 years, from 1974 to 1994, I had the great pleasure of interacting with Jack Davis on an almost daily basis, first as a graduate student and later as a faculty member. Jack's work has, of course, had a tremendous influence on the field of ingestive behavior and it should, perhaps, not be too difficult to envision how great his influence must have been on someone who occupied t...
متن کاملA real-time algorithm for acoustic monitoring of ingestive behavior of grazing cattle
Assessment of both grazing behavior and herbage intake are two very difficult tasks that can be concurrently accomplished by means of accurate detection, classification and measurement of grazing events such as chews, bites and chew-bites. It is well known that acoustic monitoring is among the best methods to automatically quantify and classify ingestive and rumination events in grazing animals...
