Abstract/ Executive Summary:

Production traits of 60 indigenous (Desi), 20 Friesian × Desi and 20 Sahiwal × Desi cows were recorded in six char villages of Sariakandi upazila (Sub-district) of Bogra district. The mean (± SD) daily milk yields were 1.7 ± 0.6, 6.3 ± 1.2 and 5.1 ± 1.0 litres, respectively. The lactation lengths, ages at puberty, gestation lengths, calving intervals, numbers of services per conception, intervals between calving and first oestrus were 217.9 ± 18.7, 253.8 ± 21.9, 240.8 ± 15.7 days; 27.4 ± 2.7, 23.9 ± 2.0, 26.2 ± 2.4 months; 277.4 ± 4.2, 278.3 ± 4.2, 278.3 ± 4.0 days; 494.8 ± 27.3, 487.5 ± 17.4, 493.3 ± 16.2 days; 1.3 ± 0.5, 1.7 ± 0.6, 1.6 ± 0.5; 145.6 ± 27.4, 166.8 ± 33.0 and 170.5 ± 34.9 days, respectively. Daily milk yield and lactation length were significantly (p<0.01) better for cross-bred cows than for Desi, and age at puberty was significantly (p<0.01) better for Friesian-cross cows than for Desi, while number of services per pregnancy and onset of post partum oestrus were significantly (p<0.01) better for Desi than for cross-bred cows. There were no significant differences in gestation length and calving interval. It is suggested that the overall productive and reproductive performance of Friesian × Desi and Sahiwal × Desi cows were better than those of Desi cows.

Location: Six char villages of Sariakandi upazila of Bogra district

Start Date: 00-07-2007

End Date: 00-11-2007

Program Area: Variety and Species

Commodity: Cattle

Objectives:

1. To determine the productive and reproductive status of cattle in selected chars of Bogra district.

Methodology:

The study was conducted in six char villages of Sariakandi upazila of Bogra district from July to November 2007, in 60 indigenous, 20 Friesian × Desi and 20 Sahiwal × Desi. The indigenous cows are Zebu (Bos indicus) type, small in size. The information on production and reproduction was collected through interviewing farmers using pre-tested questionnaires, and data obtained from the farmers’ cattle register. The following traits were used: daily milk yield, lactation length, age at puberty, gestation period, calving interval, number of services per pregnancy and onset of post-partum oestrus.The data were analyzed using analysis of variance with Completely Randomized Design. Modified Duncan Multiple Range Test (DMRT) was used for test of significance of means with unequal subclass number.

Achievement/Findings:

It may be concluded that the overall productive and reproductive performance of Friesian × Desi and Sahiwal × Desi cows was better than that of Desi (indigenous) cows. Except for the number of services per pregnancy and time to post-partum oestrus, Friesian × Desi cows were best, followed by Sahiwal × Desi and Desi cows. On the other hand, the number of services per pregnancy (1.3) and time to post-partum oestrus (145 days) were better for Desi than for Friesian × Desi and Sahiwal × Desi cows. Therefore, an upgrading programme through crossbreeding with superior bulls’ semen using AI is an option to enhance the genetic potential of these cows. However, unless we have more information on accurate phenotypes, there is an inherent risk that the genomic selection lacks proper counter-information on dairy cattle physiology, behaviour and pathological constraints, thus becoming less beneficial than expected
