Abstract/ Executive Summary:

Effects of drenching dairy cow with oil to increase milk production and to evaluate this technique as a probable low input technology for farmers were studied. The experiment was conducted at the Mannan nagar Research Station, Noakhali for a period of six months using 12 dairy cows of 2nd to 4th calving were purchased from local market. The dairy cows were divided into two groups and randomly assigned to two treatments such as oil treated group were drenched with oil measured at 0.3 % of their body weight at the beginning of the experiment and after 90 days again and without oil drenching group. Each cow received I-kg mustard oil cake and 500 g wheat bran everyday. The average milk production at the beginning of the experiment in control group (2.508 kg/d) was higher than the treated group (2.292 kg/d). In the experimental period higher milk production (2.367 kg/cow/d) was obtained from the control group than the treated (2.138 kg/d) one. However there was no significant difference (P<0.05) among them. The average feed intake of treated group (6730 g/d/cow) is higher than the control group (6.425kg/d/cow). The higher feed intake resulted in higher rate of average body weight gain in treated group (0.175 kg/d/cow) than in control group (0.098 kg/d/cow) and there was a statistically difference between them (P<0.05). This indicated that drenching of cow with oil has positive effect on body weight gain.

Commodity: Cow, Mustard cake, Milk

Objectives:

1. To determine the effectiveness of drenching cow with oil to increase milk production, and

2. To evaluate it as a probable low input technology for dairy cow farmers.

Methodology:

The experiment was conducted at a private farm (Mannan nagar Research Station),Noakhali for a period of six months from 22^nd February to 21^st August 2004.The trial designed in CRD had the following two treatments: i) Rice straw plus mustard oil cake plus coconut oil plus 500 g wheat bran and ii) Rice straw plus mustard oil cake plus 500 g wheat bran.A total of 12 local dairy cow of 2nd to 41h calving were purchased from local market and divided into 2 treatment groups of 6 cows each. Cow no 1, 2, 4, 5, 6 & 7 were in treated group and 3,8,9,10,11 &12 were in control group. Both the treatment received the following medication schedule two or more weeks before drenching with oil such as a) Helmex and b) Foot and Mouth Disease Vaccination All the animals at the oil treated group were drenched with coconut oil measured at 0.3 % of their body weight at the beginning of the experiment and after 90 days again. All the cow were fed straw and green grass ad libitum every day. Each cow received 1 kg mustard oil cake and 500 g. wheat bran everyday. Water was available throughout the trial period. Oil treated and untreated animals were kept completely separate by individual stall. No feed of either control or treatment group were shared. Labors were strictly assigned to both control and treatment group separately. Visitors were also restricted in the experimental area. Initial body weight, final body weight, feed intake and milk production of individual animal was recorded daily. Records were kept regarding any occurrence of diseases in both control and the treatment groups. Treatments for diseases were administered when necessary. In the study, F test was performed using the computer software "MSTAT C".

Achievement/Findings:

In summary the results are inconclusive, although previous research (B.L.R.l research report 2002) has shown that drenching with oil has positive effect on milk production. So more work should be done in proper way to measure these effects. In future trail, following points should be considered: in selecting concentrated feed, the amount and ingredient, there should be a feeding restriction in one treatment. More replication should be planned in the trial and previous error in the same trial must be considered.
