Abstract/ Executive Summary:

The present study was undertaken to investigate productive and reproductive performances of crossbreds and Indigenous dairy cows. A total of 400 dairy cows each are equal number of Friesian x indigenous (FI), Sahiwal x indigenous (SaI), Sindhi x indigenous (SiI) and indigenous (I) were selected from eight thanas in Jessore district. The study found that the daily milk yield from FI, SaI, SiI and I cows were 8.39 ± 2.01, 4.63 ± 0.96, 4.35 ± 1.12 and 2.38 ± 0.73 liters, respectively. The milk yield was found significantly (P<0.01) higher in first stage of lactation than that of second and third both in crossbreds and I dairy cows. The lactation period of crossbreds was significantly (P<0.01) higher than that of I cows. The service per conception was found higher in I cows and the gestation length was almost similar in all the groups. The post partum heat period and calving to first service were highest in SiI cows. The dry period and calving interval were higher in I cows. The age at first calving was almost similar in crossbreds but significantly (P<0.01) higher in I cows. The birth weight was significantly (P<0.01) lower in I than crossbred dairy cows. Considering all the parameters studied, FI showed better performance followed by SaI, SiI, and I.

Start Date: 00-11-2005

End Date: 00-04-2006

Program Area: Variety and Species

Commodity: Cow

Objectives:

1. To investigate the productive and reproductive performances of crossbreds and indigenous dairy cows in Jessore district and recommend farmers that are suitable in existing ecological and socio-economical condition.

Methodology:

Data were collected from November 2005 to April 2006. The names of selected thanas are Jhikorgacha, Sharsha, Bagharpara, Monirumpur, Keshobpur, Sadar, Chaugacha, and Avoynogar in Jessore District. A total of 120 smallholder dairy farmers, 15 from each thanas were interviewed randomly with scheduled questionnaire which was mainly based on the productive and reproductive information of Friesian x indigenous (FI) , Sahiwal x indigenous (SaI), Sindhi x indigenous (SiI) and indigenous (I) dairy cows. The questionnaire was developed in accordance with the objectives of the study and designed in a simple manner to get accurate information from the dairy farm owners. Each respondent was given a brief description about the nature and purpose of the study. The questions were asked in a very simple manner with explanation where necessary and the responses were recorded directly on the survey schedule. The farmers under the study areas maintained the dairy cows under traditional management system. They housed the dairy cows in the shed and supplied ad libitum roughage and concentrate occasionally. The parameters investigated under the study were milk production at three stage (birth-3 months, 3-6 months and 6-rest) of lactation (L/day), lactation period (day), age at first calving (month), post partum heat period (PPHP) (days), service per conception (Number), length of gestation period (days), length of dry period (days), and birth weight (kg). The data were compiled, tabulated and were subjected to statistical analyses using Completely Randomized Block Design (CRBD) to compute analysis of variance. Analysis of variance was done to come upon the differences of the productive and reproductive performances of crossbreds and indigenous dairy cows.

Achievement/Findings:

The dry period of crossbreds was significantly (P< 0.01) lower than that from indigenous dairy cows. The birth weight of SI and SaI calves was almost similar and significantly (p<0.01) higher than SiI and I dairy cows. It is assumed that crossbreds are better both for productive and reproductive performances and may recommend replacing with Indigenous dairy cows.
