Trypsin inhibitor in sow colostrum and its function.
نویسنده
چکیده
A short review is given on physical, chemical, biochemical, physiological, and functional properties of sow colostrum trypsin inhibitor. Special interest is concentrated on the physiological variations in colostrum and milk, and in serum and urine from suckling piglets. Possible significance of the inhibitor in relation to pathology is suggested.

Concentrations of trypsin inhibitor and immunoglobulins in colostrum of Jersey cows.
Colostrum samples from 49 Jersey cows were analyzed for concentrations of trypsin inhibitor, IgG, IgM, IgA, TS, fat, specific gravity, and N fractions. Colostrum (100 ml) was sampled from each cow as soon as possible after parturition. Mean concentrations of IgG, IgM, and IgA were 84.6, 3.4, and 4.5 g/L, respectively. Mean concentration of trypsin inhibitor was 56 mg of trypsin inhibited/dl of ...
متن کاملAddition of soybean trypsin inhibitor to bovine colostrum: effects on serum immunoglobulin concentrations in Jersey calves.
Secretion of trypsin by the neonate may reduce absorption of Ig from colostrum and increase failure of transfer of passive immunity, particularly for calves fed after 12 h of age. Jersey calves (n = 48) were used in a 2 x 2 factorial arrangement of soybean trypsin inhibitor (0 or 1 g) added to 1 L of maternal colostrum at the first two feedings and time of initial feeding (.65 or 12 h of age). ...
متن کاملEvaluation of a colostrum supplement, with or without trypsin inhibitor, and an egg protein milk replacer for dairy calves.
Forty-eight Holstein bull calves were assigned to a 2 x 2 x 2 factorial arrangement in a completely randomized block design. Main effects were colostrum versus a serum-derived colostrum supplement, 0 versus 1 g of trypsin inhibitor added at the initial 2 feedings, and milk replacer containing 0 or 50% CP from whole egg. Calves were bled at 0, 6, 12, 18, and 24 h after birth for determination of...
متن کاملComparison of trypsin inhibitor from colostrum with other crystalline trypsin inhibitors.
We have recently reported (2) the discovery and crystallization of a stoichiometric trypsin inhibitor from bovine colostrum. Several properties of this inhibitor indicated a close similarity to the two trypsin inhibitors from bovine pancreas, the first crystallized by Kunitz and Northrop (3) and the second crystallized by Kazal, Spicer, and Brahinsky (4). It was of interest to examine the compa...
متن کاملA colostrum trypsin inhibitor gene expressed in the Cape fur seal mammary gland during lactation.
The colostrum trypsin inhibitor (CTI) gene and transcript were cloned from the Cape fur seal mammary gland and CTI identified by in silico analysis of the Pacific walrus and polar bear genomes (Order Carnivora), and in marine and terrestrial mammals of the Orders Cetartiodactyla (yak, whales, camel) and Perissodactyla (white rhinoceros). Unexpectedly, Weddell seal CTI was predicted to be a pseu...
