External secretion monitoring method

Abstract

The invention belongs to the field of monitoring on animal internal secretion and provides an external secretion monitoring method which includes that atropine sulphate is injected into animal muscles, animals are subjected to general anesthesia, and the pancreas and the duodenum are sought; the section of the duodenum where the pancreatic duct of the pancreas is located is cut, a T-shaped pipe is inserted and two ends of a seprated duodenum section are sewed; two ends of the remained duodenum are subjected to intestinal anastomosis, another T-shaped pipe is inserted on the downstream of the intestinal anastomosis position, and a purse string suture is sewed surrounding the T-shaped pipe; and pipe openings of the two T-shaped pipes are clamped through a pair of haemostatic forceps and taken out, and peritoneum, compartment muscles and skins are sewed. According to the external secretion monitoring method, pancreatic secretion of living animals is monitored, influence of other factors on various enzymatic activities of pancreatic secretion is removed to the maximum extent, simultaneously after pancreatic secretion samples are collected, remained pancreatic secretion can flow back to the duodenum, and operation of a dairy cow digestive system is restored as far as possible. The external secretion monitoring method avoids slaughtering, saves test cost, and monitors external secretion functional changes of dairy cow pancreases in real time.

Description

technical field [0001] The invention belongs to the field of monitoring animal endocrine, in particular to a method for monitoring exocrine. Background technique [0002] As an economic animal, dairy cows play an important role in the development of modern agriculture. For high-producing dairy cows and early lactation cows, the energy feed intake often cannot meet the high lactation energy requirements. In order to solve this problem in production, the starch content in the diet is continuously increased. Starch is the main source of energy for ruminants. The starch entering the ruminant body, a part of the starch is fermented in the rumen to produce volatile fatty acids, which are absorbed by the rumen wall. The rest of the starch enters the small intestine, where it is first degraded into glucose by pancreatic α-amylase and mucosal oligosaccharides, and then absorbed by the intestinal wall into the blood. The energy utilization efficiency of starch in the small intesti...
