Background: Mammalian herbivores produce methane during digestion. Questions: Do ruminants (such as bovids) produce more methane during digestion than do equids (non-ruminants)? What are the effects of allometric scaling of methane production when different species feed on similar diets? Methods: From the literature, we collected a set of data on methane production (litres ·day) of ruminants (b...

OBJECTIVES Venovenous extracorporeal gas exchange is increasingly used in awake, spontaneously breathing patients as a bridge to lung transplantation. Limited data are available on a similar use of extracorporeal gas exchange in patients with acute respiratory distress syndrome. The aim of this study was to investigate the use of extracorporeal gas exchange in awake, spontaneously breathing she...

In Europe, especially in Mediterranean areas, the sheep has been traditionally exploited as a dual purpose species, with income from both meat and milk. Modernization of husbandry methods and the establishment of breeding schemes focused on milk production have led to the development of "dairy breeds." This study investigated selective sweeps specifically related to dairy production in sheep by...

BACKGROUND The abomasal helminth Teladorsagia circumcincta is one of the most economically important parasites affecting sheep in temperate regions. Infection is particularly detrimental to lambs, in which it can cause pronounced morbidity and severe production losses. Due to the spreading resistance of this parasite to all classes of anthelmintic drugs, teladorsagiosis is having an increasingl...

An experiment was carried out to compare the effect of feeding posidonia australis as a non-conventional feedstuff with cereal straw for sheep maintenance; and to compare seagrass/chicken litter with lucerne hay and pasture for sheep production on a scale such as would be applicable to lot-feeding of sheep in the area of suthern Australia in case of short term feed scarcity. To approach this ta...

     Meat quality and carcass composition are the most important economic traits in sheep. Body fat and fat-tail are key factors affecting carcass quality and meat production in each breed, and mutations in sequences of the genes that control these traits can affect the animal performance and therefore the breeding value. The aim of this study was to investigate the polymorphism in some regions...
