the role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of famotidine as histamine h2 -receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male ross broiler chicks reared in groups of four weeks, 16 samples (control and test ) were then inject...
A decrease in methanogenesis is expected to improve ruminant performance by allocating rumen metabolic hydrogen ([2H]) to more energy-rendering fermentation pathways for the animal. However, decreases in methane (CH4) emissions of up to 30% are not always linked with greater performance. Therefore, the aim of this study was to understand the fate of [2H] when CH4 production in the rumen is inhi...

This paper presents a method for estimating curvature values of a surface, which is given only approximatively, e.g., by measured data. The presented method requires estimates of the curvature of curves. These lead, along with the theorems from Euler and Meusnier, to the values of surface curvature. Methods are presented, which converge with the different error order of O(h2) and O(h2n). For th...
background: we aimed to evaluate effect of euphorbia royleana exposure on histocytology of corpuscles of stannius in fish, heteropneustes fossilis. methods: fish were subjected to 2.47 mg/l and 0.618 mg/l of e. royleana for short-term and long-term exposure, respectively. blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment and ...
