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...

Four lambs 4 months old were inoculated with Cryptosporidium andersoni oocysts (bovine isolate) in a dose of 5 x 10(6) per animal followed later by 1 x 10(7) oocysts per animal. No animal shed Cryptosporidium oocysts during 56 days post infection, no lamb showed clinical symptoms of cryptosporidiosis and no macroscopic changes were detected in the abomasum immediately after autopsy. Histologica...

Abstract Milk fever, or hypocalcemia, has a significant economic impact on the dairy industry and increases risk of other costly disorders including ketosis displaced abomasum. The objective this study was to identify genetic variants, genes molecular mechanisms causing variation in development milk fever. A genomic based mixed linear animal model fitted include single nucleotide polymorphisms ...

Although the nature of ruminant evolution is still disputed, current theory based on physiology and genetic analysis suggests that the abomasum is the evolutionarily oldest stomach compartment, the rumen evolved some time after the abomasum, and the omasum is the evolutionarily youngest stomach compartment. In addition, there is some evidence of relaxed selective constraint in the stomach-like ...

The effects of various selective phosphodiesterase (PDE) inhibitors on carbachol (CCh)-induced contraction in the bovine abomasum were investigated. Various selective PDE inhibitors, vinpocetine (type 1), erythro-9-(2-hydroxy-3-nonyl) adenine (EHNA, type 2), milrinone (type 3), Ro20-1724 (type 4), vardenafil (type 5), BRL-50481 (type 7) and BAY73-6691 (type 9), inhibited CCh-induced contraction...

Background: In our study, we aimed to examine the relationship between trauma-related thoracic vertebral fractures and/or rib location, age and gender. Methods: Between January 1, 2020 December 31, 2020, 100 patients with fracture were included in study. Rib analyzed according age, gender, level type. The correlation was investigated. Results: 72% of male 28% female, mean 48.49 ± 18.83. Thoraci...
