چکیده
The effect of age on the enzyme potentialities of abomasum (chymosin and pepsin) and pancreas (chymotrypsin, trypsin, lipase, colipase and amylase) was studied in the preruminant calf. Three foetuses were collected after slaughter of their dams (260 d of gestation) and 32 calves were maintained as preruminant and slaughtered between birth and 147 d of age. The abomasal mucosas and pancreata were collected and analysed. The abomasal and pancreatic glands of the foetus contained large amounts of

Minerals and some biochemical parameters determined from blood serum analyses in left displacement abomasum (LDA) affected and healthy dairy cows to evaluate the effect of displacement abomasum on mineral status, energy metabolism and liver function. Samples were collected from 60 affected cows and 60 healthy control cows matched with cases, based on herd, parity, and stage of lactation. Concen...
متن کاملDisplacement of the abomasum to the left side and pyloric obstruction in a goat
A 4-year-old female native goat with the history of inappetence and no defecation was referred to the Department of Clinical Sciences, School of Veterinary Medicine of Shiraz, Shiraz, southern Iran. During exploratory laparotomy, pyloric obstruction and displacement of the abomasum to the left side was observed. Obstruction of pylorus was due to a ball-shaped phytobezoar. The goat was followed ...
