Summary

In July 1991, 29 frozen imported Holstein Friesian embryos were transferred into synchronised recipients in Uganda. Recipient cows and heifers from indigenous breeds of cattle and their crosses in Uganda were used. The project resultéd in 17 pregnancies confirmed by rectal palpation at 8 weeks. Twelve live calves were born of which 7 were heifers and 5 were bulls. One heifer calf died at one month of age from East Coast fever. One pregnant recipient died of East Coast fever 2 months before calving. Two recipients aborted in late gestation as a result of trauma incurred during fighting. Two calves were lost as a result of dystocia. The transfer work and calvings were performed at 3 different farms under varying conditions. The 11 surviving animals are being reared on a single unit where growth rates and performance data are being recorded.

Utilisation En Ouganda De Races Bovines Locales Et De Leurs Croisements Comme Receveuses D'embryons Importes DeBos Taurus

Résumé

En juillet 1991, 29 embryons Frison × Holstein importés ont été transférés à des vaches et génisses receveuses synchronisées appartenant à des races locales et croisées en Ouganda. Il en a résulté 17 gestations confirmées par palpation rectale à 8 semaines. Douze veaux vivants sont nés dont 7 étaient des femelles et 5 des mâles. Une velle est morte de theileriose à un mois, ainsi qu'une vache receveuse 2 mois après vêlage. Deux receveuses ont avorté en fin de gestation à cause d'un traumatisme provoqué durant une lutte. Deux veaux ont été perdus à la suite d'une dystocie. Le transfert d'embryons et les vêlages ont été réalisés dans 3 fermes différentes dans des conditions variées. Les 11 animaux survivants ont été élevés dans un seul lieu où leurs taux de croissance et les données de performance ont été enregistrés.

El Uso De Razas De Ganado Criollo Y Sus Cruces En Uganda Como Recipientes De EmbrionesBos Taurus Importados

Resumen

En julio de 1991, se transfirieron 29 embriones importados de Holstein Friesian, en recipientes sincronizadas en Uganda fueron usadas como recipentes vacas y vaquillas de razas criollas y sus cruces. El proyecto resultó en 17 preñeces confirmadas mediante palpación rectal a las ocho semanas. Doce terneros nacieron, de los cuales siete fueron hembras y cinco fueron machos. Una de las terneras murió al mes de nacida de Fiebre de la Costa Este. Una de las recipientes preñadas murió la de la misma enfermedad dos meses antes del parto. Dos recipientes abortaron en el tercer tercio de la gestación, debido a traumas al pelear. Dos neonatos murieron durante partos distócicos. La transferencia se llevó a cabo en tres granjas differentes, bajo condiciones distintas. Los once sobrevivientes estan criándose en una sóla unidad, donde se estan registrando las tasas de crecimiento y otros parámetros.
