An experiment was carried out to investigate the dynamics of nitrogen (N) in the rumen and abomasum of rumen and abomasum-cannulated sheep using 15N dilution techniques. The 15N tracer was administered into the rumen as 15N-ammonia or 15N-labelled duckweed and the transfer of the 15N label to various N pools was followed. Flow of digesta from the rumen into the abomasum was ascertained by doubl...

1. The relationship between protein content of abomasal digesta and abomasal secretion of acid was studied in sheep fitted with re-entrant cannulas in the proximal duodenum. 2. A close relationship was found between the rate of passage of protein through the abomasum and acid secretion, both after varying the protein content of the rations supplied, and after direct introduction of proteins int...

Ultrasonography is an ideal diagnostic tool for investigating gastrointestinal disorders in cattle. In animals with traumatic reticuloperitonitis, inflammatory fibrinous changes and abscesses can be imaged. Ultrasonography can be used to assess the size, position, and contents of the abomasum. This article describes the ultrasonographic techniques used for examination of the reticulum, rumen, o...

Due to the need for veterinary intervention when surgery is required correct a case of left displaced abomasum (LDA) in cattle, less expensive alternative procedures have been developed. The toggle-pin suture (TPS) procedure offers lot benefits, as it minimally invasive with high success rate. purpose this report show that possible perform TPS an available and low-cost material. It about recurr...

Aim:In this study, the results of clinical, ultrasonographic, and laparotomy examinations a five-year-old dairy cow with right abomasal displacement traumatic reticuloperitonitis are presented. Materials Methods: A Holstein who had recently given birth was brought to veterinary teaching hospital history depression, anorexia, constipation, arched backs, bloat. Based on clinical ultrasonographic ...

The toxicity of DL-methionine and methionine hydroxy analog infused into the rumen or abomasum was gauged by relative feed consumption. A continuous intraruminal infustion of at least 3 days' duration of DL-methionine equalent to about 2.5% or more of dietary dry matter intake was required to reach a toxic amount. This was approximately four times the amount necessary when it was infused into t...

Objective: The cows that don’t have access to sufficient energy in their ration can get sickness. Milk production has a high priority in metabolism of dairy cows so lactating cows are more prone to get sick This can ruin all the benefits of higher milk yield because of the higher prevalence of the disorders. Methods: Data for this research had gathered from a herd with 1600 Holstein cattle in E...
