| Abstrak/Abstract |
One of the implementations of biotechnology in cattle farming in Indonesia is
crossbreeding technology between local and exotic cattle breeds using artificial insemination
techniques. This technology is already widely used to increase both production and reproduction
performance. Cows crossed with exotic breeds have proven that their offspring have better
production performance. However, their reproductive performance still needs to be studied
because selecting one superior trait can sometimes reduce other superior traits, especially in
smallholder farmer conditions that are only part-time jobs. This study aims to examine the
reproductive performance of Brahman cross (BX) cows as imported breed, compared with Ongole
Grade (OG) cows as local breed, all inseminated with the exotic Limousin semen. All cattle raised
by the smallholder farmer at Lamongan Regency, East Java Province, Indonesia, fed with king
grass, dry corn husks, and fermented corn cobs. The reproductive performance recorded included
Post Partum Estrus (PPE), Post Partum Mating (PPM), Service/Conception (S/C), Days Open
(DO) of the dams, and birth weight, weaning, and ADG of the calves. The results showed that OG
cows were better than BX (P<0.05) for PPE, PPM, S/C, DO, whereas ADG and weaning weight
of BX calves were better than local breed (P<0.05). It concluded that the implementation of
crossbreeding biotechnology at the smallholder farmer level has not been able to produce an
increase in all the desired traits. |
