متن کاملFurther studies on various aspects of the use of highcopper supplements for growing pigs.
The growth-promoting effect of the addition of 0-1 yo copper sulphate (supplying 250 p.p.m. Cu) to a growing-pig diet, reported by Barber, Braude, Mitchell & Cassidy (1955), has since been confirmed in many experiments both in Europe and America. In the present paper results of four further experiments are given dealing with: ( I ) the optimal level of copper sulphate to include in the diet; (2...
متن کاملCopper sulphate and copper sulphide (CuS) as supplements for growing pigs.
The growth-promoting effect of the addition of 0.1 % copper sulphate (supplying 250 p.p.m. copper) to a growing-pig diet, reported by Barber, Braude, Mitchell & Cassidy (1955), has since been widely confirmed. The mode of action of Cu is unknown, and whether the site of action is enteric, systemic or both remains obscure. In an attempt to throw some light on this problem, a study was made of th...
متن کاملMeta-analysis of effects of microbial phytase on digestibility and bioavailability of copper and zinc in growing pigs.
A meta-analysis was conducted to determine the effect of microbial phytase in pig diets on digestibility and bioavailability of Cu and Zn. Studies (n = 22) into effects of microbial phytase on digestibility and plasma levels of Cu and Zn were included in a dataset and regression analysis was performed to quantify the effect of Aspergillus niger derived 3-phytase in studies (n = 14) with a maxim...
متن کاملM03010 Further studies on the transmissibility of BSE to pigs
Vacuolation, spongiosis, spongiform change or micro-cavitation are synonymous terms used to describe the light microscopic appearance of pathological optically empty spaces in histological sections of the central nervous system. Similar changes can be produced in histological preparations by autolysis and tissue processing artefacts (Wells and Wells, 1989). The occurrence of neuronal vacuolatio...
