Selection of animals based on pedigree information alone is less reliable. Waiting for daughter performance for selection of bull is very costly and takes 8-10 years in Indian condition. Genomic Selection refers to selecting animals using information from pedigree as well as information on dense DNA markers (i.e. Single Nucleotide Polymorphism-SNP) spread across genome. This… Continue reading Genomics
ONBS using Multiple Ovulation and Embryo Transfer (MOET) is to set an elite herd (or a few elite herds) of males and females and carry out intensive selection and testing within herd/s selecting males and females at an early age using family information and not on their progenies as in the case of the Progeny… Continue reading Sib – selection (Open Nucleus Breeding System (ONBS))
When bulls are evaluated and selected only on the basis of performance of their parents and grand parents, the process is referred to as Pedigree Selection (PS). In a situation where a large numbers of animals of a particular breed spread over many villages in the breeding tract and where there is a limited or… Continue reading Pedigree Selection
Progeny Testing refers to evaluation of bulls on the basis of their daughter’s performance. This long term and complex programme is considered to be scientifically best approach in achieving genetic improvement in a particular breed. Progeny testing is a practical and the best option for achieving genetic improvement in the breed spread over many villages… Continue reading Progeny Testing
