“…As breeding soundness evaluation is the most practical and useful system for the estimation of bull's fertility potential (Lone et al, 2017); in this study also, a systematic and thorough bull breeding soundness evaluations were conducted to relate them with fertility potential of bulls. Nevertheless, significant differences for all the breeding soundness evaluation parameters were not recorded between Crosses and HF breeds; the study finding revealed as most of the breeding soundness evaluation parameters (Scrotal circumference, Left testis length, width, weight and volume, Right testis width, and Body weight) were significantly (P < 0.05) minimal for Boran as compared to the other two breeds.…”

This work was conducted to study the breeding soundness of semen producing bulls, their semen quality to functional tests and the inter relationship of these functional tests with spermatozoa motility percentage for the semen produced at National Animal Genetic Improvement Institute (NAGII). A total of 14 breeding bulls (Boran = 4, Crosses of 75% Holstein Frisian × 25% Boran = 4 and Holstein Frisian = 6) with respective ejaculates of 35, 33 and 57 for semen quality evaluations were considered. After physical examination of bulls for breeding soundness, semen samples were tested for functional and structural (spermatozoa acrosome integrity, viability and hypo osmotic swelling reactivity) tests and spermatozoa motility percentage using subjective and objective (computer assisted semen analysis; CASA) evaluation methods, to see the correlation of functional tests with spermatozoa motility percentage. And in the study, nevertheless, significant differences between Cross and HF breeds were not recorded for the breeding soundness evaluation parameters and for most of the semen quality parametric test values; significantly (P < 0.05) minimal and highest parametric values of the breeding soundness evaluation and semen quality were recorded in Boran and HF breeds, respectively. All the functional semen quality evaluation tests (HOST, acrosome integrity, sperm morphological defect and viability) were related in one or the other to the objective CASA individual spermatozoa motility evaluation; which were not true with subjective individual spermatozoa motility estimation. Therefore, conducting stringent breeding soundness evaluation for these breeds and evaluating their individual spermatozoa motility percentage using CASA system instead of subjective motility estimation can screen good quality semen and subsequently make possible to predict their fertility potential.

“…Breeding soundness evaluation (BSE) was introduced to identify the fertility of bulls as breeders with the requirement of having spermatozoa abnormalities <30% [1]. Boe-Hansen et al [2] stated that spermatozoa abnormalities correlated with DNA integrity and protamine deficiency, which have the potential of harming embryo development due to DNA and chromatin damage.…”

Background and Aim: Lecithin based diluent such as AndroMed, is a semen diluent made without animal components to prevent the risk of disease transmission, while glutathione (GSH) is an intracellular non-enzymatic antioxidant that prevents cell damage due to reactive oxygen species. Meanwhile, the specific impact of AndroMed and GSH combinations on spermatozoa abnormalities has not been fully studied. Therefore, this study aims to determine the effect of using cauda epididymal plasma-2 (CEP-2) and AndroMed diluents with or without the addition of GSH on the abnormalities of sexing semen of Ongole crossbred bulls in cold storage. Materials and Methods: This study used a factorial completely randomized design 2×2, the first factor was types of diluent and the second was with or without the addition of GSH. Observation of spermatozoa abnormalities was carried out at a storage time of 0-5 days using 297 ejaculations of liquid semen, with 100 spermatozoa observed per smear of each ejaculate. Furthermore, the data were analyzed using a two-way analysis of variance and the significant threshold (p-value) for statistical analysis was set at <0.05. Results: The results showed that there was a significant difference (p<0.05) between AndroMed and CEP-2 in minimizing the abnormalities of upper layer spermatozoa (X), with parameters DH and AD on day 0, damage of spermatozoa (DMR) on days 1-5, and dag-like defect (DLD) on day 5. Furthermore, spermatozoa abnormalities in the lower layer (Y) showed a significant difference between diluents in the parameters of AD on day 1, DMR on days 0-5, and DLD on days 1-5. The significant difference between with or without the addition of GSH in the X sperm was observed in the DH parameters on day 0 and DMR on 5, while there was no significant difference in the Y sperm. Conclusion: Based on the results, AndroMed has the potential to minimize spermatozoa abnormalities compared to CEP-2 diluent in sexed liquid semen. Therefore, AndroMed diluents with or without the addition of 1 mM GSH have no significant effect on spermatozoa abnormalities.

“…El desempeño reproductivo de los toros está influenciado por varios factores tales como: el desarrollo testicular, libido, habilidad para la monta, fortaleza física y calidad seminal (CS) [71]. Este potencial es examinado mediante la evaluación de la solidez reproductiva (BSE, siglas en inglés), que incluye un análisis de rutina del semen para determinar la fertilidad de los toros [41,59]. No obstante, el mismo no es capaz de determinar a priori el potencial total de los animales.…”

La presencia de toros con características seminales deficientes ocasiona fallas considerables en la eficiencia reproductiva de las unidades de producción, debido a la disminución del número de vacas preñadas, siendo más marcado en sistemas bajo programas de inseminación artificial (IA). Los rasgos de calidad seminal (CS) pueden constituir un criterio importante para la selección de machos reproductores utilizados en IA. La identificación de marcadores moleculares asociados con CS en el toro, podría facilitar la selección para estos rasgos. Este estudio tuvo como objetivo evaluar la asociación de los polimorfismos del gen Leptina, sobre la CS de toros de la raza Carora. Se evaluaron las variables volumen de eyaculado (VE), motilidad masal (MM), motilidad individual (MI) y concentración espermática (CE) de 43 toros reproductores Carora, organizados en 8 grupos de edad. Los polimorfismos nucleotídicos simples (SNP) del gen Leptina evaluados fueron: rs29004487 (SNP1), rs29004488 (SNP2), rs29004501 (SNP3) y rs29004508 (SNP4). Se utilizó un análisis de varianza mediante un modelo lineal generalizado (GLM). El factor genotipo contó con 10 niveles y el factor edad, 8 niveles. No se observó efecto del SNP1 sobre ninguna de las variables evaluadas, mientras que el SNP3 tuvo un efecto significativo sobre la CE. Los SNP2 y SNP4 presentaron un efecto altamente significativo sobre la MI y CE. Finalmente, las variables VE y MM no fueron afectadas por ninguno de los SNP estudiados. Los resultados del presente estudio sugieren marcadores potenciales para la valoración y selección genética de bovinos reproductores.
