Abstract/ Executive Summary:

Twenty Red Chittagong cows of 2^nd or 3^rd parity and at least seven months of pregnancy dividing into two equal groups were randomly fed on-farm either with a formulated diet containing calculated energy & protein according to ARC (2009) or the same diet with 25% higher concentration of the two nutrients. The former diet practically having a negative balance of the nutrients compared to ARC (2009) resulted in 0.73 MJME and 7.56 g CP intake per Kg^0.75. It showed an average pre-natal daily LW gain of 484g/head and average birth weight of 13.4 Kg/calf compared to 619g/head and 15.1 Kg, respectively of the cows fed with the other diet that resulted in daily per Kg^0.75weight intake of 1.03 MJME & 10.5 g CP. The two diets having variations in the intake of energy and protein in post-natal condition resulted in daily gain & milk yield of 122g & 1.97 Litre; and 274g & 2.5 Litre, respectively.

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

To develop a feeding strategy for RCC cows at the community level of Chittagong.

Methodology:

Twenty RCC cows having 7 month of pregnancy and within 2 or 3 parities were selected at Latabania, Dolir Gopat, Fokirkhil and Notunhat villages under Satkania upazila of Chittagong district, and randomly allocated into two dietary treatment groups for a study period from March 15 to August 15, 2013. One group (T₁) was planned to supply with as per required ME and CP according to NRC while another group (T₂) received 25% above the requirements. Conventional feeds of cattle of the study area were firstly identified by interviewing farmers against open questionnaire. Intake of conventional roughage and concentrate daily used by farmers were measured by top loading balance for a period of 7 days. Average values of intake were used to calculate the conventional nutritional status of cows. All feed samples were collected and analyzed for proximate composition at Animal Nutrition Laboratory of Bangladesh Livestock Research Institute, Savar, Dhaka. Then required nutrition for T₁ and T2 groups of cattle were supplied by formulating concentrate mixture at every 15 days interval on the basis of live weight of animals and stage of pregnancy of cows. In case of lactating cows, in addition to maintenance requirement, nutrient requirements for producing 3L milk daily were considered in formulating concentrate mixture. ME and CP requirement for 1L milk production was 5.28MJ and 40g, respectively according to following equations. Data on live weight gain of cows, birth weight of calves, milk yield and post-partum days were recorded and analyzed for Paired-Samples t-Test to compare means using SPSS.

Total Budget (Tk.) : Tk. 10.00 Lac

Achievement/Findings:

Improved feeding of cows by supplying ME and CP by 14 MJ and 64g, daily than requirements during the last 2 months of pregnancy can give higher live weight gain of cows and birth weight of calves. Postnatal milk yield and live weight gain of cows can be improved by supplying higher ME and CP by 3.64MJ and 93g daily than requirements during the first 2 months of lactation.
