Abstract/ Executive Summary:

The aim of this study was to investigate the feed and nutrient intake, requirement, nutritional status, productive and reproductive performances of pre-natal Red Chittagong cows (RC) under small-scale farm feeding condition. To achieve the aim, a total of ten farmers were randomly selected. Farmers who had at least one pre-natal RC cow were involved in this study. Ten pre-natal RC cows from each of 10 farmers having six months pregnancy and between 2 and 3 parities were selected. The experiment was carried out in Satkania Upazila of Chittagong district of Bangladesh for a period of three months from April 2010 to June 2010. The owner offered feeds to their cows. Animals were fed in stall. The offered feeds and leftover feeds were weighted and recorded daily. The cows were weighed individually at weekly interval and recorded regularly. The intake of total dry matter (DM), metabolizable energy (ME) and crude protein (CP) were 3.39 kg, 27.49 MJ and 279 g per cow per day, whereas, the DM, ME and CP requirements were 4.89 kg, 39.0 MJ and 454g, per cow per day, respectively. The deficiency of DM, ME and CP were 1.50 kg, 12.11 MJ and 189 g, per cow per day, respectively. The total live weight gain of pre-natal RC cows was 14.50 kg. The calf’s birth weight was 10.95 kg. The going experiment revealed that the nutritional status of pre-natal Red Chittagong cows was negative balance.

Objectives:

To assess the feed and nutrient intake, requirement and nutritional balance of pre-natal RC cows under small-scale farm feeding condition of Satkania Upazila of Chittagong district of Bangladesh.

Methodology:

Selection of Study Area and Duration of Study- This experiment was carried out under small-scale farm in Satkania Upazila of Chittagong district of Bangladesh for a period of three months from April to June 2010. Selection of Pre-natal Red Chittagong Cows- The experiment was carried out with ten pre-natal Red Chittagong cows. Farmers who had at least one pre-natal Red Chittagong (RC) cow were involved in this study. A total of ten farmers were randomly selected. The pre-natal RC cows from each of 10 farmers having six months pregnancy and between 2 and 3 parities were selected in this experiment. Housing and Feeding Management Practices- The pre-natal RC cows were reared by the owners under their own feeding and management practices of farms condition. The cows were kept in separate conventional house. All cows were stall fed and followed stall feeding system. The rice straw and naturally grown grasses were given twice daily, between 06:00 to 07:30 hours in the morning and between 15:30 to 16:30 hours in the afternoon. The rice straw supplied first followed by freshly cut naturally grown grasses. The rice bran as concentrate diet (polish and husk) was fed twice a day in the morning and afternoon after feeding of roughages. The weight of roughages and rice bran were taken by using a top loading balance before supplying and recorded regularly. There was accessed of clean fresh drinking water, ad libitum to all the experimental animals. Estimation of Feed and Nutrient Intake- The feed was weighted daily before supplying. The leftover feeds were also weighted and recorded on the following morning before offering morning feed. The daily feed intake was determined by subtracting the amount of leftover from the amount of feed given on the previous day. The metabolizable energy (ME) and crude protein (CP) was determined from the amount of dry matter (DM) fed in 24 hours. The ME and CP values were determined by multiplying respective ME and CP values of feeds. Calculation of CP Values of Intake Diet- The calculation of CP values of intake diet based on ARC. Weight Determination of Pre-natal Red Chittagong Cows and Their Calf Birth Weight- The pre-natal experimental RC cows were weighed individually at weekly interval by using portable digital weighing balance and recorded regularly. The weight of RC cows was performed in morning before feeding. The birth weight of calf was taken immediately after born by using the digital weighing balance and recorded. The placenta was also weighed and recorded. Collection and Chemical Analysis of Feed Samples- The rice straw, natural grasses and rice bran samples were collected from the study area for chemical analysis. The samples were cut into small pieces for determining DM content of fresh sample. At the same time, another portion of samples were dried in the sun and then grinded to pass through 40 mm mesh sieve. After grinding, the samples were kept in the polythene bags, labeled and stored. Dry matters of feeds were determined immediately after collection. The fresh samples were dried at 55°C for 72 hrs in a forced drying oven to determine DM content. The sun-dried samples were subjected to chemical analyses for organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE), Ash and nitrogen free extract (NFE) following the procedure AOAC. The metabolizable energy (ME) was determined by using the in-vitro gas production techniques. All the samples were analyzed in duplicate and mean values were recorded. Nutrient Requirements of Pre-natal Red Chittagong Cows- The daily dry matter (DM), metabolizable energy (ME) and crude protein (CP) requirements of post-natal RC cows were calculated based on ARC. Data Collection and Statistical Analysis- A formatted register was supplied to the farmers for keeping record. The data on daily feed intake, weekly live weight, date of service, date of calving, calf birth weight and placenta weight were recorded and collected for statistical analysis. The data were analyzed by using the Microsoft Office Excel Worksheet 2007. Mean values and standard error difference were calculated.

Achievement/Findings:

The feed and nutrient intake of the going experiment gave an idea that the pre-natal nutritional status of Red Chittagong cows was deficit. The pre-natal nutrition of cows affect the live weight gain of cows before calving and calf birth weight. Therefore, it can be concluded that the small-scale farm feeding would be urgently improved to obtain optimum production from pre-natal RC cows.
