in order to evaluate the quantitative and qualitative forage characteristics of different sainfoin ecotypes, a field experiment was conducted in a randomized complete block design (rcbd) with three replications at the research station of agricultural college of shahrekord university. in this experiment, the amount of wet and dry weight of above-ground plants, plant height, and the protein and f...

The aim of this study was to use meta-analysis to identify the enteric methane (CH4) mitigation strategy that reduced CH4 emission without lowering production. To this end, a database initially developed was updated, compiling data from 61 publications (233 experiments) for various observations in dairy cattle on effects of hydrogen sink (H-sink), ionophore, lipid and conc...

Insulin resistance, the key defect in type 2 diabetes (T2D), is associated with a low capacity to adapt fuel oxidation to fuel availability, i.e., metabolic inflexibility. This, in turn, contributes to a further damage of insulin signaling. Effectiveness of T2D treatment depends in large part on the improvement of insulin sensitivity and metabolic adaptability of the muscle, the main site of wh...

This thesis consists of studies concerning the effects of dry period energy feeding, and early lactation energy and protein feeding on the metabolic and hormonal status, tissue mobilisation and lactation performance in dairy cows. In all studies, restricted amounts of grass silage were fed during the dry period, and lead feeding with concentrate was applied during the last three weeks of pregna...

In Exp. 1, individual performance and daily DMI was measured on 70 crossbred weaned calves during a 70-d period using a GrowSafe system (GrowSafe Systems Ltd., Airdrie, AB, Canada) at the University of Florida North Florida Research and Education Center Feed Efficiency Facility (FEF). Calves were fed a low-concentrate (LC) growing diet, blocked by weight and sex, and then randomly assigned to p...

BACKGROUND Dairy cows are often fed a high-concentrate diet to meet lactating demands, yet long-term concentrate feeding induces subacute ruminal acidosis (SARA) and leads to a decrease in milk fat. Stearoyl-CoA desaturase1 (SCD1) participates in fatty acid biosynthesis in the liver of lactating ruminants. Here, we conducted this study to investigate the impact of lipopolysaccharide derived fro...

INTRODUCTION Kyphoscoliosis, which is a deformity of the spine caused by aging and osteoporosis, results in various surgical difficulties for laparoscopic cholecystectomy (LC) due to low-lying costal arches, such as a small abdominal working space, disturbance of the surgical view and decreased controllability of the surgical instrument. PRESENTATION OF CASE We herein report the case of a 92-...

Background: Sainfoin (Onobrychis viciifolia) is a forage crop that yields high in arid and calcareous soils cultivated large areas. There aren’t many genetic diversity studies on the varieties of cultured sainfoin. This study was conducted to determine degree relationship between 23 landraces one registered variety. Methods: To take samples from populations, seeds were sown field 2014. Samples ...

This study entails a pharnutcokinetic analysis of the relationship between the external dose of 2,3,7,8tetrachlorodibenzo-p-dioxin (dioxin, TCDD) and resulting concentrations of TCDD in internal tissues and organs of humans and rodent species. The methodology is based on the development and testing of physiologically based pharmaeokinetic models for several rodent species and humans. The result...

A new cell immobilization method based on the replacement of KC1 by KC1 +chitosan as gelling agent was developed. The results showed that through addition of chitosan into gelling agent, the mechanical strength and thermal stability of the carrageenan gel were greatly improved. The new immobilization method was used to entrap a chlorophenol-degrading microorganism. The immobilized microbial cel...
