Background: There is empirical evidence that the presence of a companion animal can have a positive impact on performance.The available evidence can be viewed in terms of differing hypotheses that attempt to explain the mechanisms behind the positive effects.Little attention has been given to motivation as a potential mode of action with regards to
The antibacterial effect of Thyme species was relatively approved but the effect of this plant on bacterial population of intestine in chickens and consequently on bacterial load of chicken meat following administration of thyme was not investigated.For evaluation read more of thyme effect on growth indices, microbial contamination of meat and micr
The mineral composition, lithofacies association, pore-fracture type, pore structure and pore development control of the Qianjiang Formation shale oil reservoir in the Qianjiang Sag of the Jianghan Basin were studied using thin section petrography, scanning electron microscopy, mercury injection-liquid nitrogen adsorption and 3D reconstruction of m
Hive thermoregulation is fundamental for the normal development of bee colonies and, consequently, hive productivity and honey bee health.External conditions mainly affect the walls of the hive.Therefore, hive construction materials and thermal conductivity features can influence its thermoregulation efficiency.The present trial made a comparison o
The gill is an important organ in fish that is involved in various physiological functions, 9002nc including respiration, filter-feeding, ammonia nitrogen excretion, and osmoregulation.The physiological functions of gills are closely related to their structure, external feeding conditions, and environmental factors.Herein, we first briefly summariz
