Abstract/ Executive Summary:

This experiment was conducted in the Animal Genetic Engineering of Biotechnology and Genetic Engineering Discipline at Khulna University, Bangladesh during the period of 2010-11. A total of 20 pure, crossbreed and local cattle were randomly selected from cattle shades of Central Cattle Breeding and Dairy Farm, Saver, Dhaka and the morphological characters were studied. The cattle breeds were also compared with high yielding exotic breeds as PHF, LF 75% and LF 50% based on discrete external morphological traits. The UPGMA dendrogram shows that four breeds of cattle divided in three main clusters. The maximum genetic distance was found between Local (Pabna) and LF 75%, which was 1.1896. The minimum genetic distance was obtained between LF 75% and LF 50%, which was 0.4964. This indicates the close relationship between LF 75% and LF 50%.

Keywords: Holstein-Friesian and local dairy cows, Morphological characters, Genetic distance

Location: Animal Genetic Engineering of Biotechnology and Genetic Engineering Discipline at Khulna University, Bangladesh

Start Date: 00-00-2010

End Date: 00-00-2011

Program Area: Variety and Species

Commodity: Cattle

Objectives:

The present study was, under taken to find out the morphological characters of selected Holstein-Friesian and local dairy cows.

Methodology:

This experiment was conducted in the Animal Genetic Engineering of Biotechnology and Genetic Engineering Discipline at Khulna University, Bangladesh. The morphological characters were studied in Central Cattle Breeding and Dairy Farm, Saver, Dhaka. The following materials and methodologies were used in the laboratory for DNA extraction and quantification of Holstein-Friesian and local dairy cows blood samples. Animal selection and blood sample collection - A total of 20 pure, crossbreed and local cattle were randomly selected from cattle shades of Central Cattle Breeding and Dairy Farm, Saver, Dhaka, for this study. Five or ten ml of blood was collected from each animal in 10 ml EDTA vaccutainer tube. The blood was gently mixed with EDTA (present in the vaccutainer as an anticoagulant agent) and kept on ice box to maintain low temperature in order to prevent cell. Subsequently the blood samples were transported to the laboratory and stored at 0ºC.

Achievement/Findings:

From the morphological characters the genetic identity and genetic distance were estimated using soft-ware POPGENE (Version 1.31). The maximum genetic distance was found between Local (Pabna) and LF 75%, which was 1.1896. The minimum genetic distance was obtained between LF 75% and LF 50%, which was 0.4964 (Table 8). This indicates the close relationship between LF 75% and LF 50%.
