K.  aIntrogression of FecB gene in non-prolific Malpura indian sheep for increasing litter size.  aIn: WORLD CONGRESS ON GENETICS APPLIED TO LIVESTOCK PRODUCTION, 8., 2006, Belo Horizonte, MG. Proceedings... Belo Horizonte: Instituto Prociência, 2006. 4 f. 1 CD-ROM.c2006  aWith the aim to augment prolificacy, prolific Garole rams were crossed with Malpura sheep. Results show that crossing of Garole with Malpura sheep increased litter size and fecundity gene has been incorporated into the Garole X Malpura (GM) genotype. The fertility %, lambing rate and litter size in Malpura vs. GM were 86.99 vs. 89.19, 90.52 vs. 138.57 and 1.04 vs. 1.56, respectively. This genetic group is adaptable under semi-arid region of the country and it might prove a valuable germplasm towards evolving a new prolific strain of sheep having optimum body weight for enhancing mutton production in the country. Further, there is a need to strengthen the GM half-breds population and the ewes of this genetic group are required to be backcrossed with Malpura for minimizing the differences in the body weight maintaining prolific genes.  aEwes  aFecundity  aIndia  aLitter size  aSemiarid zones  aSheep  aOvino  aFecB  aGene Booroola  aProlificidade1 aARORA, A.
