Abstract/ Executive Summary:

This study was done to investigate the productive and reproductive performances of Holstein Friesian crossbred (HF) and indigenous (IG) cows. A total 131 dairy cows of two genetic groups as IG (117 heads) and HF (14 heads) were selected randomly. The study found that the average milk yield per day of HF and IG cows were 7.64±1.74 and 1.75±0.07 liters/day, respectively. The milk yield was found significantly (p<0.01) higher in HF cows than of IG cows. The lactation period of HF was significantly (p<0.05) higher than of IG cows. Age at first calving of IG cows was significantly (p<0.01) 4 months higher than HF cows. The number of service per conception was almost similar for HF and IG cows. Higher significant difference was found in Post-partum oestrus (p<0.05), dry period (p<0.01), calving intervals (p<0.01) of IG than HF cows. The gestation length of HF and IG cows was significantly indifferent. Above biological studies mentioned better productive and reproductive performance of HF cows than IG cows.

Location: Uzankashiar Char Village, Mymensingh.

Start Date: 00-01-2014

End Date: 00-06-2014

Program Area: Farming System

Commodity: Cow

Objectives:

To investigate the productive and reproductive performances of HF crossbred and IG cows in Uzankashiar Char Village, Mymensingh.

Methodology:

This study was conducted at Uzankashiar Char Village, Mymensingh, for the period of six months from January to June 2014. A total 131 dairy cows of two genetic groups as IG (117 heads) and HF (14 heads) were selected randomly. The questionnaire was developed in accordance with the objectives of the study and designed in a simple manner to get accurate information. Each respondent was given a brief description about the nature and purpose of the study. The questions were asked in easy way with explanation where necessary and the responses were recorded directly on the survey schedule. The farmers followed the traditional management system for rearing the cows. The cows, which have at least three lactation periods, were only used for this study. The basal diet was rice straw with 3 to 4 hours grazing in a day. Concentrates (rice polish, common salt.) were also supplied once a day. The parameters envisaged in the study were milk production (L/day), lactation length (days), age at first calving (months), service per conception (number), post-partum oestrus (days), dry period (days), calving intervals (days), gestation length (days). All values relating to production and reproduction of HF and IG cows were expressed as Mean±SD. The statistical analyzes were done using Statistical Package for the Social Science (SPSS), version 16. Paired sample ‘t’ test was done to find out significant differences in production and reproduction parameters between HF and IG cows.

Achievement/Findings:

This study revealed that the performance of Holstein Friesian crossbred cows was better in terms of production and reproduction than that of indigenous cows. For the development of dairy production in Bangladesh, Holstein Friesian crossbred cows can be reared specially in the area where the bank of the river can be used as grazing land.
