To determine whether the uterus was the source of serum pregnancy-specific protein B (PSPB) after calving, five beef cows were hysterectomized at 21 d postpartum and five served as intact controls. A single blood sample was taken from all cows immediately after calving and then twice weekly until 21 d postpartum. Beginning on d 22, blood samples were taken(More)
OBJECTIVES To use lipopolysaccharide (LPS) to create synovitis in the midcarpal joint of ponies, and to assess the morphologic, histochemical, and immunohistochemical effects of synovitis on articular cartilage of the third carpal bone. ANIMALS 2- to 3-year-old ponies, 6 control (group 1) and 6 treated (group 2). PROCEDURE Synovitis was induced in 1(More)
Results from 2286 non-surgical embryo transfers were analyzed to find relationships between embryo factors and recipient factors that affect pregnancy. Pregnancy rates from morulae (44%) and advanced morulae (53%) were reduced (P < .05) when compared to early blastocysts (65%), blastocysts (65%), blastocysts (66%) and advanced blastocysts (64%). Pregnancy(More)
 Isoniazid (INH) continues to be a highly effective drug in the chemoprophylaxis and treatment of tuberculosis; however, its use is associated with hepatotoxicity (predominantly hepatic necrosis) in 1–2% of individuals. The INH metabolites, acetylhydrazine and hydrazine, have each been implicated as the causative hepatotoxin in INH-induced hepatotoxicity.(More)
Eleven 3-yr-old crossbred Angus cows that had raised one calf each were mastectomized at 6 to 7 mo of their second gestation. All calves were removed from cows within 12 h after birth. Cows were kept in a drylot with a fertile bull for 60 d after parturition. Cows were observed for estrus every 6 h, and blood serum was collected daily and assayed for(More)
Forty-six crossbred Hereford heifers were allotted into five experimental groups. Fenprotalene, a prostaglandin analogue, was administered to induce abortion and (or) to regress the corpus luteum (CL) in four groups of heifers about 75 d after conception. The four groups were 1) pregnant heifers, 2) pregnant heifers with the ovary contralateral to the(More)
OBJECTIVE To develop and validate a gas chromatography-mass spectrometry (GC-MS) method for determination of Ntau-methylhistamine (NMH) concentration in canine urine and fecal extracts and to assess urinary NMH concentrations in dogs with mast cell neoplasia and fecal NMH concentrations in dogs with protein-losing enteropathy. SAMPLE POPULATION Urine(More)
Superovulation and embryo transfer records on performance of embryo donor (n = 3,908; beef 99%, dairy 1%) and recipient (n = 19,936; beef 92%, dairy 8%) cattle from a commercial transfer unit were analyzed for environmental effects. Embryos (n = 42,428) were recovered on Days 5 to 8 postestrus from superovulated donors. Numbers of ova, fertilized ova and(More)
