Influence of Osteopontin in Bovine Uterine Tube Fluid on Sperm Binding and Fertilization in RCA-1 Lectin-treated Oocytes     

RF Gonçalves  CG Wolinetz  VH Barnabe  GJ Killian 《Reproduction in domestic animals》2009,44(1):152-155

This study was conducted to determine the effect of pre‐exposure of oocytes to Ricinus communis (RCA‐1) lectin and osteopontin (OPN) in uterine tube fluid (UTF) on in vitro sperm–egg binding and fertilization. In vitro‐matured bovine oocytes were incubated (39°C, 5% CO₂ in air) for 2 h in the following treatments: (i) 500 μl of fertilization medium (FM); (ii) 250 μl of FM with 0.25 ml of non‐luteal ampullary uterine tube fluid (NLAUTF); (iii) 250 μl of FM with 250 μl of NLAUTF and 4 μl of RCA‐1 lectin; (iv) 250 μl of FM with 250 μl of NLAUTF, a rabbit polyclonal antibody (1:200) against purified bovine milk OPN, and RCA‐1 lectin; (v) 500 μl of FM and RCA‐1 lectin. Following incubation, oocytes were washed, placed in FM with 2 μg heparin, and incubated with 1 × 10⁵ frozen–thawed spermatozoa per 10 oocytes. Oocytes used to assess sperm binding were stained with Hoescht 33342, and the number of sperm bound per zona pellucida counted. The remaining oocytes were fixed in acid alcohol, stained with 1% acetate‐orcein and observed to determine the presence of pronuclei. More sperm bound to the zona pellucida (mean ± SEM) when oocytes were incubated in treatment 3 (59.0 ± 5.5) than in treatments 2 (46.4 ± 5.6), 4 (18.1 ± 5.4), 5 (33.4 ± 5.6) or 1 (32.5 ± 5.6). More oocytes were fertilized when incubated in treatment 3 (91% ± 3.0) than in 2 (84% ± 3.0), 4 (40% ± 3.0), 5 (77% ± 3.0) or 1 (76% ± 3.0). As in previous studies, this study suggests that RCA‐1 lectin enhances binding of UTF‐derived OPN to bovine oocytes, resulting in increased sperm–egg binding and fertilization in vitro and a possible role in fertilization.  相似文献

The incidence of bone lesions in the carpal and tarsal regions and the rate of physeal closure in weanling quarter horses     

J.A. Reynolds BS  E.L. Morris DVM  D.M. Senor MA  K.S. Frey BS  D. Reagan BS  V.A. Weir ARRT  J. Elslander RVT  G.D. Potter PhD 《Journal of Equine Veterinary Science》1992,12(2)

Sixty weanlings were maintained in dry lots without forced exercise and individually fed a diet consisting of 25% Bermudagrass hay and 75% balanced concentrate twice dally. Radiographs of the carpus, metacarpus and first phalanx, and other radiographs of the tarsal region, were taken initially at approximately 180 d of age and at approximately 236, 292 and 348 d of age. The radiographs were evaluated for the presence or absence of subchondral and/or cystic lesions in the carpal and tarsal regions and for closure of physes of the distal third metacarpus and proximal first phalanx. Physeal scores were: 1 = open; 2 -- partially closed; 3 = closed. Only 1.7% of the horses had subehondral lesions in the carpal region at 180 d, and none had those lesions at 236, 292 or 348 d. There was a 3.3% incidence of subchondral lesions of the tarsus at 180, 236 and 292 d, but only 1.7% at 348 d. Cystic lesions of the carpus were evident in 13.3% of the horses at 180 d, 16.7% at 236 d and 18.3% at 292 and 348 d. None of the hrses had cystic lesions oftbe tarsus at 180, 236 or 348 d, but 1.7% had them at 292 d. Physeal closure scores for the distal metacarpus averaged 1.5 and 2.6 at 180 and 236 d, respectively. At 292 and 348 d, all of the distal metacarpi were closed. Physeal closure scores for the proximal first phalanges were 1.5, 2.6 and 2.9 at 180,  相似文献

Beef customer satisfaction: cooking method and degree of doneness effects on the top round steak   总被引：1，自引：0，他引：1  

Neely TR  Lorenzen CL  Miller RK  Tatum JD  Wise JW  Taylor JF  Buyck MJ  Reagan JO  Savell JW 《Journal of animal science》1999,77(3):653-660

The objective of this research was to evaluate the consumer-controlled factors of cooking method and degree of doneness on Top Choice, Low Choice, High Select, and Low Select top round steaks. The in-home product test was conducted in Chicago, Houston, Philadelphia, and San Francisco. Consumers (n = 2,212) evaluated each top round steak for overall like (OLIKE), tenderness (TEND), juiciness (JUIC), flavor desirability (DFLAV), and flavor intensity (IFLAV) using 23-point hedonic scales. Stir-frying, braising, and simmering and stewing consistently produced higher consumer attribute ratings. There were clear OLIKE rating differences (P = .0001) for top round steaks among the four cities. The highest ratings were given by consumers in Houston, and the lowest ratings were given by consumers in Philadelphia (P < .05). There were two interactions for OLIKE: USDA quality grade x degree of doneness (P = .002) and degree of doneness x cooking method (P = .02). Higher ratings generally were given to steaks cooked to medium rare or less or to very well degrees of doneness. Stir-frying, braising, and simmering and stewing were preferred at lower degrees of doneness. Customer satisfaction with the top round steak is very dependent on how it is cooked and by whom it is consumed.  相似文献   

Effect of exogenous porcine somatotropin on the functional and textural characteristics of the porcine semimembranosus muscle     

M F Miller  S M George  J O Reagan 《Journal of animal science》1991,69(5):1975-1982

Sixteen barrows and gilts (sex effects were balanced within treatment, but not included in the model for analysis) were used in a 2 (porcine somatotropin; 2 mg.animal-1.d-1 vs control) X 2 (10% dietary fat vs control) X 4 (time postmortem; 0, 3, 6, and 24 h) factorial treatment array to evaluate the effects of porcine somatotropin (pST) administration and level of dietary fat intake on the functional and textural characteristics of the semimembranosus muscle during the first 24 h postmortem. Porcine somatotropin administration resulted in a decrease (P less than .05) in muscle tenderness, an increase (P less than .05) in chilled carcass weight, and an increase (P less than .08) in longissimus muscle area. The pH values were lower over time with elevated levels of dietary fat, but pST resulted in no alterations in muscle pH. The R-values (the ratio of inosine to adenine nucleotides) were unaffected by pST or by level of dietary fat, but the combination of the two resulted in an increase in moisture binding capabilities. It could be concluded from the present study that pST and increased level of dietary fat result in an alteration of certain functional (tenderness) and textural (water binding ability and cooking losses) characteristics of the porcine semimembranosus muscle.  相似文献
