| Sumario: | [EN] Early studies developed at l'Institut de Ciencia i Animal Technology (ICTA) of the Polytechnic University of Valencia (UPV) showed enough differences between the Murciano-Grenadians kids (MG) pure and crossed Boer (BO). However, the fact of selecting the wrong way crossover MGxBO animal as a pure MG may have consequences for the future of milk production, which requires a deeper study of the differences being them. The aim of this work is to increase awareness of the morphological characteristics of MG kids and from the crossing of MG with meat Boer breed. 195 kids, of whom 109 were crossed MGxBO and 86 kids pure MG, were used. Once reached 9 kg of live weight were measured a series of quantitative and qualitative morphological variables on animals. The main morphological feature to differentiate between crossed kids and pure MG is the color of the layer, since in the first only 10% are single color brown or black (the rest are pintos, with a stain or fairly large white area) while in the second monochrome 100% are brown or black. A second characteristic morphological differential would be the shape of the ears. In crossed kids, 80% are wholly or partially falls, 20% are horizontal and there is no case with pricked ears. We conclude that these differences visually, can be helpful in goat farms to carry out the crossing of MG males Boer goats |
