Abstract/ Executive Summary:

A field survey was made to assess the lactation performances of native cattle of Khulna region. The survey also included the effects of rice straw and concentrate feed on their lactation performances. The average daily milk yield, lactation length and total milk production were found to be 2.49 ± 0.06 kg, 247.23 ± 3.51 days and 590.40 ± 15.00 kg, respectively. The effects of rice straw and concentrate feed supplement were found highly significant (P<0.001) for all the traits under consideration.

Keywords: Lactation; Native cattle; Bangladesh; Khulna

Location: Semi-urban areas adjacent to the Khulna City

Start Date: 00-10-1998

End Date: 00-01-1999

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

The purpose of the study is to assess the performances of milk production of native cattle as well as the effects of rice straw and concentrate feed supplement on various milk production traits.

Methodology:

The field survey was carried out in the semi-urban areas adjacent to the Khulna City. Data were collected by a prepared questionnaire and the survey covering 112 randomly selected farmers during October 1998 to January 1999. The animals under consideration were grazed regularly on grasses growing naturally on uncultivated government or private land and roadsides. However, the grazing hours were variable. In addition, cattle were fed with rice straw and concentrate mixtures as supplement. The quantity of concentrate feed supplied to the animals was 0.25kg to 7.0 kg/animal/day, where a small number of farmers supplied no concentrate feeds. The main ingredients of concentrate feed were rice polish, oil cake, wheat bran and pulse bran. The ratio of ingredients was variable from farmers to farmers. The following lactation performances were considered: daily milk yield, lactation length and total lactational production.

The data analysis was done by a statistical package MINITAB. Analysis of variance was carried out on each of the traits for rice straw and concentrate feed supplement.

Achievement/Findings:

It was concluded that the rice straw and the concentrate feed supplement have significant influences on lactation performances of native cows. So emphasis should be given on proper supplementation of rice straw and concentrate feeds in addition to grazing to obtain the maximum yield of milk from the native cows.
