“…Results on the performance of such crosses in well-designed experiments have, however, only been available since 1930 and a great number of reports have been published since then. It has now become clear from studies carried out by Amble and Jain (1967); Mason (1974); Katpatal (1977); Kimenye (1978); Rege (1998) ;Demeke, Neser and Schoeman (2004a) and Gaur, Garg and Singh (2005) that where cattle management is good, the performance of cross-breds increases with the number of B. taurus genes, and that the breeds that have 50 or 75 percent of these genes perform better than all other levels of exotic inheritance. Animals with these levels of B. taurus blood calve earlier than the indigenous stock, produce more milk, and have longer lactations and shorter calving intervals (CIs).…”

SummaryThis paper reviews experiences with cross-breeding for milk production in the tropics. Data were compiled from 23 different studies evaluating the performance of different grades of cross-bred animals as well as local breeds. Relative performance of indigenous breeds compared with different grades of cross-breeds was calculated for three climatic zones. Traits considered were milk yield per lactation, age at first calving, services per conception, lifetime milk yield and total number of lactations completed. At 50 percent Bos taurus blood, lactation milk yields were 2.6, 2.4 and 2.2 times higher than those of local cattle in the highland, tropical wet and dry, and semi-arid climatic zones, respectively; lactation lengths increased by 1.2, 1.2 and 1.9 months in the above-mentioned climatic zones, respectively; there was a reduction in calving interval by 0.8 times and in age at first calving by 0.9 times. Similarly, cross-breds with 50 percent B. taurus genes had 1.8 times higher lifetime milk yields and a 1.2 times higher number of total lactations. Although cross-breeding faces a number of challenges such as better infrastructure, higher demand for health care, there are many advantages of using it. These are higher production per animal, higher income for the families and provision of high-value food. It is therefore likely to continue to be an important livestock improvement tool in the tropics in the future, where farmers can provide sufficient management for maintaining animals with higher input requirements and access to the milk market can be secured.Keywords: Cattle, cross-breeding, milk production, tropics ResumenEste artículo hace un repaso por las experiencias obtenidas con el cruzamiento de razas para la producción de leche en los trópicos. Se recopilaron datos de 23 estudios diferentes que evaluaron los rendimientos de animales con distinto grado de cruce así como de animales de razas autóctonas. Se compararon los rendimientos de las razas autóctonas con los de animales con distinto grado de cruce para tres zonas climáticas. Las características consideradas fueron el rendimiento lechero por lactación, la edad al primer parto, el número de servicios por concepción, la producción lechera total a lo largo de la vida del animal y el número total de lactaciones completadas. Con un 50 por ciento de sangre Bos taurus, los rendimientos lecheros por lactación fueron 2,6, 2,4 y 2,2 veces mayores que los del ganado bovino autóctono en las zonas climáticas de las Tierras Altas, Tropical Húmeda y Seca y Semiárida, respectivamente; la duración de la lactación se incrementó en 1,2, 1,2 y 1,9 meses en las zonas climáticas anteriormente mencionadas, respectivamente; el intervalo entre partos y la edad al primer parto se redujeron, respectivamente, 0,8 y 0,9 veces. Asimismo, los animales cruzados con una genética 50 por ciento Bos taurus tuvieron rendimientos lecheros, para la totalidad de su vida productiva, 1,8 veces mayores y un número total de lactaciones 1,2 veces mayor. Si bien el cruzamiento implica afr...

“…Efforts to determine the optimum levels of Bos Taurus inheritance in different geographical tracts of India started in the 1950s (Amble and Jain, 1967), with varying levels of success. Among these was a four breed crossing scheme initiated at the Indian Veterinary Research Institute in 1968.…”

Vrindavani is an Indian composite cattle breed developed by crossbreeding taurine dairy breeds with native insicine cattle in the 1960s. About 190,000 semen doses of Vrindavni bulls have been distributed to the farmer till date. the animals are under artificial and natural selection for higher milk production and adaptation traits in the Vrindavani genome is not explored. In this study, we provide the first overview of the selection signatures in Vrindavani genome. 96 Vrindavani cattle were genotyped using BovineSNP BeadChip and the SNP genotype data of its constituent breeds were collected from a public database. Within-breed selection signatures in VRindavani were investigted using the integrated haplotype score. Vrindavani was also compared to each of its parental breeds to discover between-population signature of selection using two approaches, cross population extended haplotype homozygosity and fixation index. Signature of selection identifies 11 common region identified by more than one mthod harbouring gene such as LRP1B, TNN13K, APOB, CACNA2D1, FAM110B and SPATA17 associated with production and adaptation. Overall, our results suggest stronger selection pressure on regions responsible for adaptation compared to milk yield.

“…This is mainly due to all genetic factors that contribute to adaptation also contribute indirectly to the performance traits. Amble and Jain (1967) showed that halfbred European and halfbred Zebu breeds in India have shown superiority for adaptability and longevity more than the other grades of European breeds deviated from halfbreds. Gregory (1981a, 1981b) found that Sahiwal crosses with Bos taurus had higher potential in milk and beef production and adaptability in several ecological zones of Africa.…”
