Abstract
The study was conducted to know the effects of several genetic and non-genetic factors like season, sex, year of birth, genotype of calves and milk yield of dam associated with growth performance of crossbred calves. Data were collected from registered farmers during the period of May, 2011 to April, 2013. Birth weight, three-month weight, six-month weight, weaning weight and heritability estimates of those growth performances were performed using a total of 82 registered calves which had pedigree information having the genotypes of 25% Local - 75% Friesian and 37.5% Local - 62.5% Friesian. The average birth, three-month, six-month and weaning weight of calves were 29.33, 64.32, 99.06 and 151.77 kg, respectively. The effects of non-genetic factors like sex, season of birth and genotype were non-significant (P>0.05) for the traits birth weight, three-month, six-month, weaning weight and average daily gain of calves. However, year of birth was found significant on birth (P

Summary
It is evolving in response to continuously growing demand for livestock products. Livestock in Bangladesh are important in many ways; as employment generation, store of wealth; form of insurance, recycle of waste products and residues from crops and agro-industries, improvement of the structure and fertility of soil and in controlling pests. The cattle population is 23.34 million (BER, 2013). It is depicted that there is a remarkable shortage of livestock products in Bangladesh for human consumption. When livestock performance is considered, it depends mainly on the genetic potential of the animal. Improvement in genetic capabilities as well as environment could only be the suitable way for animal improvement. Knowledge on selection and breeding program and management practices is very essential to increase the productivity of cattle. Genetic parameters like heritability, repeatability and genetic correlation are inevitably important in all the situations (Bhuiyan, 1999)
