Abstract/ Executive Summary:

The production traits of Red Chittagong Cattle (RCC) were studied using two diets: A [Urea-molasses-rice straw (UMRS), Green Grass and Concentrate] and B [Rice straw, Green Grass and Concentrate]. In cows fed diets A and B, birth weights of calves were 15.2 and 14.1 kg (P<0.05), daily milk yield 2.0 and 2.0 kg (P>0.05), lactation length 254.8 and 247.1 days (P>0.05), age at first oestrus 28.4 and 25.6 months (P<0.05), number of services per pregnancy 1.6 and 2.5 (P<0.05), onset of postpartum oestrus 141.3 and 109.3 days (P<0.05), calving interval 14.2 and 13.3 months (P<0.05), semen volume per ejaculation 3.0 and 3.7 ml (P<0.05), mass activity of sperm 58.6 and 68.4% (P<0.01) and sperm concentration 709.1 and 1289.0 million/ml (P<0.01), respectively.

End Date: 00-00-2008

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

1. To find the impact of feeding straw treated with urea and molasses on some productive traits in RCC.

Methodology:

Source of animals and data - The data on productive and reproductive performance of RCC and their progenies were extracted from the records at the Bangladesh Agricultural University (BAU) Dairy Farm and Artificial Insemination (AI) Center, Mymensingh from 2005 to 2008. Feeding and management practices in RCC nucleus herd - The nucleus herd of RCC was stall-fed throughout the year. Rice straw, the main feed, was provided in two forms: straw alone, and straw treated with urea and molasses, ad libitum. Maize and German grass (Echinocloa crusgalli) were fed to the animals at 10, 5, 3 and 2 kg/head/day for stud bulls, lactating cows, pregnant cows and heifers, respectively. Concentrate was provided to the animals in the morning at 2.0, 0.5, 0.4 and 0.25 kg/head/day for stud bulls, lactating cows, pregnant cows and heifers, respectively (Table 3). Clean drinking water was supplied ad libitum. Vaccination against Anthrax was done annually. Foot and Mouth Disease vaccine and anthelmintics were given every six months. Birth weight, lactation length and milk yield were recorded. Statistical analysis - The data were entered into Microsoft Excel worksheet, organized and processed for further analysis. Means and standard errors were calculated using Statistical Packages for Social Science (SPSS-10.0) computer program. To find out the effect of feeding trials, least significant difference (LSD) was tested with analysis of variance (ANOVA) using the procedure by SPSS-10.0.

Achievement/Findings:

It would appear from this study that a urea-treated diet is not suitable for a breeding bull, because it decreased quantity and quality of semen.
