(1) It was concluded that ochratoxin A was cleaved into the nontoxic ochratoxin alpha and phenylalanine by the contents from all but the abomasum.
(2) Each of the primary stress selected isolates was tested in synthetic saliva, rumen fluid simulating the activity in the rumen, rumen fluid followed by pepsin-hydrochloric acid treatment simulating the additional effect of ruminal and abomasal activity, pepsin-hydrochloric acid solution simulating conditions in the abomasum and finally in a trypsin solution as an example of enzyme activity in the gut.
(3) The ratio of methane (CH4) to CO2 in the abomasum gas was higher than that in the rumen.
(4) The availability and utilization of cystine and methionine were measured in single-bearing Merino ewes on three occasions, approximately 90, 110 and 130 days after mating, and the effects on these traits of sulfur amino acids (SAA) infused into the abomasum were also measured.
(5) At slaughter, the abomasum and pancreas of each animal were collected and the gastric (chymosin and pepsin) and pancreatic (chymotrypsin, trypsin, lipase and amylase) enzymes were assayed.
(6) Because of the various complications associated with blind-stitch percutaneous abomasopexy, we concluded that it is not an appropriate procedure for correction of left displaced abomasum in valuable cattle, but may be used as an alternative for salvage in less valuable cows.
(7) One square centimetre samples were taken from equivalent areas in each case of the rumen, reticulum, omasum and abomasum of 38 embalmed Karakul lambs.
(8) Perforation of the abomasum occurred in one lamb only.
(9) The research was carried out on the vorestomachs, abomasum and on the various tracts of gut of adult Cattle, Sheep and Goat, because Ruminants, not previously studied with respect to this problem, have, as is well known, particular morpho-functional characteristics of the digestive system.
(10) The mucus from the small intestine and abomasum paralysed and inhibited larval migration from agar gels significantly more (P less than 0.01 and P less than 0.05, respectively) than corresponding mucus from parasite-free control animals.
(11) The rumen, abomasum duodenum, jejunum, ileum and colon were all able to acetylate aniline.
(12) The flow of sulphide, sulphate, microbial S and non-microbial organic S from the abomasum was estimated using 103Ru and 51Cr.
(13) Complete emptying of the abomasum was observed within three hours of feeding in the majority of lambs aged four hours (seven out of eight) and 120 to 144 hours (13 out of 16) but only in a minority of lambs aged 24 to 48 hours (one out of 11).
(14) Rates of twins, stillbirth, milk fever, prolapsed uterus, retained placenta, primary metritis, displaced abomasum, ketonuria, and aciduria were 5.8, 6.3, 1.4, 3, 17.8, 36.1, 1.7, 30.4, and 29.5%, respectively.
(15) Necropsy revealed abomasal distention, with various degrees of abomasitis, hemorrhage, and ulceration, but did not reveal evidence of displaced abomasum or obstructed intestine.
(16) One square centimetre samples were taken from analogous areas of the rumen, reticulum, omasum and abomasum of 38 embalmed Karakul lambs.
(17) The microbiological and physiological changes occurring in the abomasum of sheep after infection with H. contortus are discussed with reference to these results.
(18) Four Holstein male calves each were fitted with a reentrant duodenal cannula and fed a low heat milk replacer with or without an oxalate-NaOH buffer known to prevent curd formation in the abomasum.
(19) The investigations were carried out in 3 male sheep on the effect of Estrumate (a synthetic analogue of PGF2 alpha) on the secretion and composition of juice from the "small" abomasum.
(20) By percussion left displaced abomasum (LDA) was identified in a 7-month pregnant Ayrshire cow which had presented with progressive abdominal distension despite a 5-day history of inappetence.
Abomasus
Definition:
(n.) The fourth or digestive stomach of a ruminant, which leads from the third stomach omasum. See Ruminantia.
