O rebanho foi mantido em pastagem nativa, e durante a epoca seca, recebeu silagem de sorgo e milho com farelo de soja. O trabalho teve como objetivo determinar as caracteristicas de producao de leite de cabras Tricross-G1 e suas bimesticas-G2(G1 x G1), no semi-arido. As matrizes tricross-G2 foram 21,6 e 22,2% inferiores as tricross-G1, para a producao total acumulada de leite aos 150 dias e producao media diaria de leite aos 150 dias, provavelmente em funcao das perdas por heterose, ja que as mesmas foram submetidas ao mesmo plano nutricional. [Milk production traits in ½ Anglo Nubiana + ¼ Pardo Alpina + ¼ Moxotó goats]. Abstract: It was evaluated the daily mean production of milk from two breeds Three-cross, from 586 lactations. The flock was kept in native pasture with supplementation during the dry season, the animals received sorghum silage and concentrate of corn plus soybean. This work had the purpose to determine the milk production of goats Threecross-G1 and Threecross-G2 (G1 x G1), in the semi-arid. The females G2 were 21,6 and 22,2%, less productive than G1 respectively, for milk production accumulated and daily mean production during 150 days. This result probably is due to losses in heterosis, since the animals were submitted to the same nutrition plan.  aBrazil  aCrossbreds  aDairy goats  aGenetic improvement  aHeterosis  aMilk  aSemiarid zones  aCabra  aCaprino  aCruzamento  aMelhoramento genético animal  aProdução leiteira  aVigor híbrido  aCrossbreeding  aGenetic groups  aHeteresis  aHybrid vigour1 aARAÚJO, A.
