Feeding Intervention of Milk Cows for Improving Milk Yield

Dr. Md. Jasimuddin Khan
Professor (Livestock Systems Specialist)
Department of Animal Nutrition, Bangladesh Agricultural University, Mymensingh-2202

Abstract/ Executive Summary:

Significantly higher milk production were observed on cows on supplemented feeding practice. From the table it revealed that from the initial the milk production increased up to 2 months of lactation. Then the milk production decreased gradually in supplementary group A, B and C. But in non supplementary group from the initial the milk production decreased gradually and finally less than 1 liter at 4 months of lactation.Appreciable differences were noted in weight gain of calves between categories, although the differences in case of cows were small. Live weight gain of cows and calves ranged from -1.6 to 20 g d-1 and calves 425 to 451gd-1, respectively in supplementary group.

Start Date: 01-11-2010

End Date: 29-02-2013

Program Area: Animal Health and Management

Commodity: Cow

Objectives:

To improve milk productivity of cow through improved feed supplementation
To see the economic performance due to feed supplementation.

Methodology:

The study was conducted at village Purbo Tethulia during 1 November 2010 to 29 February, 2011. Eighteen milking cows of second lactation between 1-10 days of milk production and yielding up to 3 liters of milk were selected in the study area. On the basis of milk production the cows were divided into three groups viz., more than 2 liters(A), 1-2 liters(B) and less than 1 liter milk having six animals in each group. These six milking cows of each group further grouped into two viz., feed supplemented and non supplemented group. All the farmers were given training on feed preparation, feeding practices and management. The cows belonging to non-supplementary feeding group reared following farmers usual feeding and management practices .The supplementary groups were supplied improved feed of 500g mustard oil cake + 500g rice polish,375g mustard oil cake + 375 g rice polish and 250g mustard oil cake + 250 g rice polish to cows belonging group A, B and C, respectively. Rice straw + green grass and clean drinking water were fed adlibitum to all cows. Deworming was done before the commencement of the trial. Records were kept monthly on live weight of cows and calves and daily milk yield of cows.

Achievement/Findings:

Farmers showed a positive attitude and they were interested to continue this program. The technology needs to be disseminated among the farmers.It may be recommended to supply a mixed concentrated feed containing 500g of sesame / mustard oil cake and 500 g rice polish to the cow yielding more than 2 liters of milk per day and 375 g sesame / mustard oil cake and 500 g rice polish for cow yielding 1-2 liters of milk daily.
