Genetic analysis of phenotypic indicators for heat tolerance in crossbred dairy cattle por Oloo, Richard Dooso, Ekine-Dzivenu, Chinyere C., Mrode, Raphael A., Bennewitz, J., Ojango, Julie M.K., Kipkosgei, Gideon, Gebreyohanes, Gebregziabher, Okeyo Mwai, Ally, Chagunda, M.G.G.

“…Climate change-induced rise in global temperatures has intensified heat stress on dairy cattle and is contributing to the generally observed low milk productivity. Selective breeding aimed at enhancing animals’ ability to withstand rising temperatures while maintaining optimal performance is crucial for ensuring future access to dairy products. …”

Trypanotolerance, an option for sustainable livestock production in areas at risk from trypanosomiasis por D'Ieteren, G.D.M., Authié, Edith, Wissocq, N.M., Murray, M.

“…The decreasing efficacy of available trypanocidal drugs and the difficulties of sustaining tsetse control increase the imperative need to enhance trypanotolerance through selective breeding, either within breeds or through cross-breeding. …”

Aspects of bull reproduction with emphasis on cattle in Ethiopia. II. Sperm production capacity and semen characteristics por Tegegne, Azage, Kassa, T., Mukasa-Mugerwa, E.

“…If improvement in cattle production is envisaged in the coming years, appropriate bulls election criteria have to be established and applied and controlled and selective breeding of cow herds should be implemented. This paper examines available information on bull reproduction in Ethiopia and highlights the different physiological functions of the bull in relation to reproductive performance. …”

“…Genetic correlations between androstenone and skatole may allow one to reduce boar-taint by selective breeding, using individuals with low levels of androstenone. …”

Creating a low enteric methane emission ruminant: What is the evidence of success to the present and prospects for developing economies? por Goopy, John P.

“…It is concluded that to date, there is little in vivo evidence to support the practical success of any of these strategies, save selective breeding, and this at a high cost with unknown efficacy. …”

Rich food for poor people: Genetically improved tilapia in the Philippines por Yosef, Sivan

“…The Genetic Improvement of Farmed Tilapia (GIFT) project, which operated from 1988–97, served as a launching point for tilapia improvement efforts in Asia, as well as tropical finfish genetic improvements globally. Based on the selective breeding of Nile tilapia, the GIFT project succeeded in producing tilapia with faster growth rates, higher survival rates, and a shorter harvest time, thus increasing fish yields dramatically. …”

Practicalities of sustaining a goat-crossbreeding programme in eastern Ethiopia por Ayalew, W., King, J.M., Bruns, E.W., Rischkowsky, Barbara A.

“…Observations on flock dynamics patterns of smallholder flocks with crossbred goats showed that the desirable attributes of crossbreeding had not been maintained after the promotion phase because: 1) the pool of crossbred goats was too small to maintain 50% exotic blood level in the crossbreeds; 2) shortages of crossbred breeding males also led to gradual back crossing of the does, resulting in an increasingly mosaic mix of crossbreeds; 3) the small size of flocks as well as their rapid turnover limited the scope for any selective breeding and the maintenance of superior breeding animals; and 4) losses control on the breeding of various classes of crosses with indigenous goats posed undesirable dissemination of introduced genes into the indigenous genetic pool. …”

Screening of blood and mucus parameters towards breeding for resistance to salmon louse (lepeophtheirus salmonis) in atlantic salmon por Amit, Das

“…In the absence of an effective vaccine, inefficiency of biological control methods and growing concerns over the usage of chemical treatments, there is a quest for alternative strategies to combat this problem. This includes selective breeding approach to increase the innate resistance in fish to the parasite. …”

Den svenska lapphunden - en ras i behov av förändring? por Karlsson, Jenny

“…Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. …”
