Intestinal Disaccharidase Activ It Ies of Three Breeds of Swine 1'2
نویسنده
چکیده
Total lactase and sucrase activities in the mucosa of the small intestine were determined from four pigs of the Hampshire (H), Duroc (D) and Yorkshire (Y) breeds at approximately 6 months of age. All pigs were fed a conventional 14% protein corn-soybean meal diet. Lactase (g lactose hydrolyzed/24 hr) and sucrase (g sucrose hydrolyzed/24 hr) activity differed (P<.01) among breeds, as Y had 2.5fold greater activities than H or D. In a second trial, the effects of differences in intestinal lactase activity upon weight gain were evaluated in 5-month-old pigs (10H,IOD and 10 Y) fed a control or 30% lactose diet. There were no significant differences among breeds or between diets in average daily gain during the first 14 days. Cecal and large intestinal lactase activities were increased (P<.01) in the pigs fed lactose, with no differences among the three breeds. Lactase activity (dry matter basis) was similar for cecal and colon contents. In a third study, total mucosal lactase, sucrase, and maltase activities were estimated in 30-day-old gilts from the three breeds. Lactase activity in Y was higher (P<.05) than D, with H being intermediate. Sucrase and maltase activities did not differ among breeds. (

2. With the ourified diet there were no differences in bodv-weight or small intestinal di. sacchnridase activities between germ-free and conventional chicks. With the chick mash the germ-free birds were heavier and had higher total amounts of maltase, sucrase and palatinase activities in the small intestine than did their conventional controls. When disaccharidase activities were expressed in t...
متن کاملCombined assessment of intestinal disaccharidases in congenital asucrasia by differential urinary disaccharide excretion.
Investigation of intestinal disaccharide hydrolysis and permeability by means of a non-invasive differential sugar absorption test was performed in a family containing two siblings with primary sucrase-isomaltase deficiency. The procedure, which depends on measurement of urinary excretion ratios after the oral administration of lactose, sucrose, palatinose, lactulose and L-rhamnose, is capable ...

The Mangalitsa pig, a swine breed belonging to the protected gene fund of original and primitive animal breeds of the FAO (Food and Agriculture Organization), has been known to inhabit Romanian territories since the 19th century. The aim of this study was to compare the Mangalitsa breed with several European and Asiatic swine breeds in order to emphasize its uniqueness and to elucidate its orig...
متن کاملIntestinal disaccharidase activity in rosacea.
Recently intestinal disaccharidase deficiency has been identified as one cause of carbohydrate intolerance (Durand, 1958; Auricchio et al., 1963; Kern et al., 1963 ; Dahlqvist, 1964; McMichael et al., 1965; Sheehy and Anderson, 1965). The disaccharidases are produced and act within the cells of the intestinal epithelium (Miller and Crane, 1961). Enzyme deficiencies may be found singly or combin...

Electron microscopy was used to measure microvillous surface area in seven small intestinal biopsies showing secondary disaccharidase deficiency and in five biopsies having normal disaccharidase levels. There were significant reductions in microvillous surface area in the enzyme deficient group, although the microvilli were not severely damaged. Histological abnormality was not always present w...
