Sows of the Finnish Landrace and Yorkshire breeds (L and Y) were artificially inseminated with mixed semen of Finnish Landrace and Yorkshire boars. Purebred and crossbred progeny were identified by blood group testing. The pairs of boars were selected to be as identical as possible in regard to semen quality. Mixing of the two diluted semen fractions did not affect unfavourably the viability and motility of the sperm. Normal conception rates and litter sizes were obtained. The progeny fell into groups as follows: LL 34, YL 28, YY 24, and LY 20 piglets. The distribution, however, varied greatly within the various litters. One litter consisted merely of purebreds. The sires were successfully determined by blood group testing in 95 % of the Cases. The crossbred piglets grew very significantly (P < 0.001) faster than the purebreds. They also were more vital than the purebreds. In carcass characteristics the purebreds and crossbreds were either similar to each other or the crossbreds represented intermediate forms between the two parent races.

Emergency Situations

Blood group testing is one of the vital tasks in the area of medicine, in which it is very important during emergency situation before victim requires blood transfusion. Presently, the blood tests are conducted manually by laboratory staff members, which is time consuming process in the emergency situations. Blood group identification within shortest possible time without any human error is an important factor and very much essential. Image processing paves a way in determining blood type without human intervention. Images which are captured using high resolution microscopic camera during the blood slide test in the laboratory which are used for blood type evaluation. The image processing techniques which include thresholding and morphological operations are used. The blood image is separated into sample wise and blood type is decided based on the agglutination effects in those sample images. This project facilitates the identification of blood group even by common people who are unaware of the blood typing procedure.

Abstract The objective of this study was to examine the relationship between semen quality and conception rate. There were 30985 Duroc, 15888 Landrace, and 18198 Yorkshire single sire, purebred mating observations with 880 Duroc, 508 Landrace, and 492 Yorkshire boars represented from March 2011 to July 2018. Data from each breed was analyzed using a logistic regression model with fixed effects of sow parity at time of mating, the number of breeding attempts for the sow, days rest of the boar, and days from collection to insemination, covariates of age at collection, motility, percent abnormal tails, and random effects of contemporary group, boar, and evaluator. For Duroc, increased percent abnormal tails decreased conception rate (odds ratio=0.99, P < 0.05), and more than 9 days rest resulted in lower conception rates compared to less than 5 days rest (odds ratio=0.85, P < 0.05). For all three breeds, inseminations occurring 2 days post-collection tended to result in lower conception rate compared to 1 day post-collection (Duroc, odds ratio=0.94, P < 0.1, Yorkshire, odds ratio=0.87, P < 0.1, Landrace, odds ratio=0.91,P < 0.05); however, for Landrace, inseminations occurring 4 days post collection resulted in higher conception rates compared to 1 day post-collection (odds ratio=1.16, P < 0.05). For Yorkshire, increased motility was associated with higher conception rates (odds ratio=1.02, P < 0.001). The effect of age at collection on conception rate was small, but significant for both Landrace and Duroc resulting in ~1% increase per year of age (P < 0.05). Boar and semen quality effects on conception rate were inconsistent across breeds, suggesting that optimizing conception rates across breeds could be difficult.

Blood Grouping

Background: Blood grouping consists of both forward grouping; reverse grouping and both procedures should agree with each other.A blood group discrepancy exists when results of red cell testing do not agree with serum testing, usually due to unexpected negative or positive results in either forward or reverse typing. ABO and Rh blood group discrepancy is associated with incompatible transfusion reaction.Blood group discrepancy should be resolved before transfusion and blood group to be properly labeled to prevent transfusion reaction.Methods: A prospective study was carried in SCB blood bank which is under the Department of Transfusion Medicine, SCB Medical College and Hospital, Cuttack, Odisha from January 2015 to October-2016. Total 25,559 blood samples of patients were included in the study and hemolysed samples excluded. The ABO and Rh D typing was done by tube technique using monoclonal IgM (Tulip Diagnostic P Ltd.) Anti-A, Anti-B, Anti-D and pooled A, B and O cell.Results: A total of 25,559 blood group testing were done where we found 57 blood group discrepancies with overall frequency was 0.22%. Out of 57 discrepancies we were found 20 (35.09%) cases of technical error and 37 (64.91%) cases of sample related error. Among these sample related problems, we found weak/missing antibody, weak antigen expression, rouleaux, cold autoantibodies, cold alloantibodies, Bombay phenotype with the frequency of 13.51%, 2.70%, 2.70%, 54.06%, 8.11%, 18.92% respectively.Conclusions: Mistyping either a donor or a recipient can lead to transfusion with ABO-incompatible blood, which can result in severe hemolysis and may even result in the death of the recipient. Any discrepancy between forward and reverse blood grouping methods should be resolved before transfusion of blood components.
