Abstract/ Executive Summary:

The result of the collected data revealed different reproductive performances of Red Chittagong Cow such as age at puberty 2.68±1.72 years, days required to first heat during post partum period 3.08±1.00 months, calving interval 14.00±1.19 months, service per conception 1.36±0.60 and gestation length 279.92±5.27 days. In this survey some data were recorded to observe the production performances of Red Chittagong Cows. Milk production per day and lactation length was 2.10±0.63 liter and 238.8±30.6 days, respectively. The maximum milk production per day was 4 liter per cow and the minimum production was 1 liter per day per cow. The cow produced 1.88±0.51 liter milk supplied with roughage only on the other hand 2.42±0.57 liter milk produced by the cow supplied some amount of concentrate along with roughage. The level of production difference between two groups were highly significant (p<0.0001).

Program Area: Animal Health and Management

Commodity: Cow

Objectives:

The following objectives: a. To know the existing reproductive and productive performances of Red Chittagong Cow in rural condition. b. To know the management practice of RC cow in Chittagong region under rural condition. c. To know the effect of feed on milk production

Methodology:

The study was conducted at the five thanas namely Potia, Rawjan, Satkania, Candhanish and Anwara located Chittagong district in Bangladesh. These five thanas were selected on the basis of number of RCC observed frequently. Before site selection, a good relationship was built up with different relevant offices and other related people in the project areas. District Livestock offices were played an important rule to get more information and easy to collect data. After site selection a survey was made by going door to door of farmers who are rearing RCC and a total 250 cows were selected (50 cows from each thana) from different selected upazillas during the period May 07 to June 08. The selected cows were visited frequently and the information on the productive and reproductive performances of each cow was collected by face to face interviewing the farmers by frequent visit and examination of the cow. After that, all data were recorded in a separate designed survey questionnaire prepared according to objectives. Before interviewing the farmers were given a brief description about the purpose of this study. The survey schedule was prepared on the basis of following key items: age at puberty, gestation length, days to post partum heat, calving interval, days open, age at first calving, service per conception, daily milk production per cow, total lactation length. During investigation the management including feeding, housing, ventilation, hygiene etc were also observed and recorded the in the questionnaire. The studied animals were divided into tow groups; group A (animals were supplied Roughage only) and group B (animals were supplied concentrate plus Roughage). Diseased animals were also treated if any during farm visit. Statistical Analysis: Collected data were compiled and entered into Microsoft excel and the data were analyzed for Student ‘t’ test using SPSS.

Achievement/Findings:

The result of this study revealed that reproductive and productive performances of Red Chittagong Cow in rural area are sustainable though the milk production is low. The management practice of RCC in rural area in Chittagong is ordinary. Average production of milk from RCC is low but it can be significantly increased by supplying roughage with concentrate. However further study will be required to observe the productive and reproductive performances of RCC supplying with balance feed and providing well reproductive herd health management.
