Abstract/ Executive Summary:

This experiment was conducted at Buffalo Breeding and Development Farm, `Bagerhat` a southern district of Bangladesh to investigate the milk (lactation) yield, lactation length and calf mortality rate of Nili-Ravi and crossbred buffaloes. From this study it was revealed that the average milk yield per lactation of Nili-Ravi and crossbred buffalo cows were 1161.805±684.07 and 696.636±258.68 liters respectively, while their average milk production per day were 3.5 and 2.24 liters. On the other hand average lactation length for same genotypes were 330.426±70.08 and 311.556±74.14 days respectively. The overall calf mortality rate was 24.28% and the average calf mortality rate for Nili-Ravi and crossbred buffalo were 37.1 and 14.1 percent respectively. Statistical analysis showed that there were significant variation (p<0.01) existed between Nili-Ravi and crossbred buffalo calves in respect of calf mortality. From the study it may be concluded that Nili-Ravi buffaloes are better than crossbred buffaloes considering specially on milk production mentioned in the Buffalo Breeding and Development Farm, Bagerhat, Bangladesh.

Keywords: NiIi-Ravi, Crossbred, Milk yield, Lactation length and Calf mortality

Location: Buffalo Beeding and Development Farm at Bagerhat.

Start Date: 00-01-1999

End Date: 00-04-1999

Program Area: Animal Health and Management

Commodity: Buffalo

Objectives:

To determine and compare the productive performance of NiIi-Ravl and crossbred ( NiIi-Ravi X Local) dairy buffalo cows raised In farm condition

Methodology:

The experiment was conducted at Buffalo Beeding and Development Farm at Bagerhat from January to April 1999 to investigate the milk production, lactation length and calf mortality rate of Nili-Ravi and Crossbred buffaloes. There is only one government buffalo farm in Bangladesh. This farm is located at Fakirhat under Bagerhat district and known as Buffalo Breeding and Development Farm. This farm within an area of 80 acres was set up in 1984 - 1985 fiscal year by the Department of Livestock Services under the ministry if Livestock and Fisheries to produce outstanding buffalo bulls and cows for Increasing the productivity of this animals in the country. The main consideration in selecting this Buffalo Breeding and Development Farm at Bagerhat of Bangladesh were as follows: 1. A large number of Nili-Ravi and Crossbred (Nili-Ravi X Local) buffalo cows. are raised in that farm. 2. This is only government buffalo farm where no study of this type was conducted previously. At first there were some Murrah and NiIi-Ravi buffalo cows and bulls transferred from Savar Dairy Farm and Tejgaon Dairy Farm. Hundred (100) Buffalo cows were purchased from different locations of Bangladesh in between 1986 to, 987. Besides this 100 Nili-Ravi buffaloes were imported from Pakistan in 1990 and most of them were pregnant heifers and first lactating cows. During this research period the farm consisted of NiIi-Ravi, Crossbred (NiIi-Ravi X local) and some indigenous. There were about 255 buffaloes of different age and sex groups. The heifers, dry cows and milch cows (after milking) are allowed to graze in the field until late noon. After grazing and allowing they were driven back to stall. There they were fed green grasses like napier, para, german, oat etc. on the basis of year round availability and straw ad libitum. Concentrate feeds (include wheat bran, rice bran, oilcake and salt) were also provided. The amount vary depending upon sex and age group.The following parameters were studied to determine the productive performance of different buffalo cows: 1. Lactation (Milk) yield, 2. lactation length and 3. Calf mortality rate. The data were collected from records kept by the farm personnel. Respondents were given a brief description about the nature and purpose of this study. During data collection careful attention was given to attain accurate and reliability of data. Data collected from records kept by the farm personnel were processed, tabulation and analyzed in accordance with objectives of the study. Analyses were mainly done through graphical form. Similarly analyses of variance test was done to find out statistical difference treatments.

Achievement/Findings:

The overall calf mortality rate was 24.28 %. The average calf mortality rate for NiIi-Ravi and Crossbred buffalo were 37.1 % and 14.1 % respectively. Chi-square test indicated that statistically significant variation (p < 0.01) existed between NiIi-Ravi and Crossbred buffalo calves. Jogi and Lakhani found that the average mortality rate of Murrah buffalo calves was 16.a6 %. From the study It may be concluded that NiIi-Ravi buffalo cows are better than that of Crossbred buffalo cows considering specially on milk production in Bangladesh.
