Abstract/ Executive Summary:

The aim of the experiment was to reveal the production potential of lactating Red Chittagong cows through improved feeding. To achieve the aim, the experiment was designed in a completely randomized design with three dietary treatment groups having ten Red Chittagong cows in each group for a period of six months. The cows were randomly allocated to three dietary treatment groups, i.e., T₀, T₁ and T₂. The cows of T₀ group received only farmers’ diet (63% of dry matter intake of cows according to ARC, 1995) without the supplementation, served as control. The cows of T₁ group received farmers’ diet (63%) plus 25% supplementation of formulated concentrate diet for deficit of requirement of cows {(63 + 9.25) = 72.25% dry matter intake of cows according to ARC, 1995)} and T₂ group received farmers’ diet (63%) plus formulated concentrate diet to meet 100% requirement of cows according to ARC (1995) {(63% + 37%) = 100%}. The average milk production of Red Chittagong cows of T₀, T₁ and T₂ groups was 2.40, 3.27 and 4.82 kg per day, respectively. The milk fat, protein, solids not fat, total solids and ash were 4.30, 3.85, 9.02, 13.34 and 0.70; 4.75, 3.70, 8.97, 13.73 and 0.71; and 5.45, 3.56, 8.86, 14.30 and 0.72, g per 100 g milk, respectively, for T₀, T₁ and T₂ groups. Therefore, the farmers’ diet plus supplementation of formulated concentrate diet (FCD) to meet 100% requirement of cows was a better improved feeding system of lactating Red Chittagong cows to derive good performance.

Program Area: Animal Health and Management

Commodity: Cow

Objectives:

To study the effect of improved feeding on productive performances of lactating Red Chittagong cows of Satkania Upazila of Chittagong district.

Methodology:

Preparation of supplemented concentrate diet: The supplemented concentrate diet was formulated by mixing wheat bran, mustard oil cake, rice polish, rice bran, common salt and dicalcium phosphate in the proportions of 12, 14, 37, 33, 2 and 2 kg per 100 kg, respectively to maintain the required levels of ME and CP. The ingredients were selected depending on the availability in the local market. Ingredient composition of formulated concentrate diet with energy and protein values is presented. Chemical composition of roughage and concentrate feeds: The chemical composition is done by following the procedure of AOAC. 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. Deficit of nutrient requirements of lactating RC cows according to ARC: The deficit nutrient requirement of lactating RC cows is presented. Place and duration of the study: The experiment was conducted under on-farm condition of Satkania Upazila of Chittagong district in Bangladesh. The duration of experiment was six (6) months from April 2011 to September 2011. Selection of lactating Red Chittagong cows: Farmers who had at least one lactating Red Chittagong (RC) cow were involved in this study. A total of thirty (30) farmers were randomly selected. Immediately after calving thirty cows with one from each of 30 farmers between 2 and 3 parities were used in this experiment. Experimental treatments: The experiment had three dietary treatment groups having ten cows in each group. The cows were randomly allocated to three dietary treatment groups, i.e., T₀, T₁ and T₂. The cows of T₀ group received farmers diet (63% of dry matter intake of cows according to ARC, 1995) without the supplementation of formulated concentrate diet (FCD), served as control. The cows of T₁ group received farmers’ diet (63%) plus 25% supplementation of formulated concentrate diet (FCD) for deficit of requirement of cows {(63 + 9.25) = 72.25% dry matter intake of cows according to ARC 1995)} and T₂ group received farmers’ diet (63%) plus formulated concentrate diet (FCD) to meet 100% requirements of cows according to ARC (1995) {(63% +37%) =100%}. Housing and feeding management of lactating Red Chittagong cows: The experimental lactating RC cows were kept in traditional housing. The roughage were given twice daily at between 06:00 to 07:30 hours in the morning and at between 15:30 to 16:30 hours in the afternoon. Rice straw was offered at the beginning followed by natural grasses (Cut and carried system). The total amount of formulated concentrate diet was portioned into two and supplied twice a day before milking of cows in the morning at between 08:00 to 09:00 hours and afternoon at between 15:30 to 16:30 hours. The total amount of FCD was adjusted based on the week of the experiment. The roughage and FCD were weighted and recorded before supplying. Fresh drinking water was accessed ad libitum to all the cows at all the times. Estimation of feed and nutrient intake: The feed intake was defined as the quantity of feed that an animal consumes in 24 hours per 100 kg live weight as well as per unit of metabolic live weight (W^0.75). The daily offered rice straw, natural grasses and formulated concentrate diet were weighted and recorded 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 per 100 kg live weight and per unit of metabolic live weight (W^0.75). The ME and CP values were determined by multiplying respective ME and CP values of feeds. Nutrient requirements: The calculations of daily dry matter (DM), metabolizable energy (ME) and crude protein (CP) requirements of lactating RC cows were calculated based on ARC. The M/D values and CP values of feeds were also calculated based on ARC.

Weight determination of lactating Red Chittagong cows and calves: The cows were weighed individually at weekly interval from the start till the end of the trial and recorded regularly. The weight of cows was performed in morning before feeding. The calves were also weighed individually at weekly interval and recorded from the start till the end of the trial. The weight of calves was taken before milking. Data collection and record keeping: Collection of data on different parameters has been done for a period of 6 months. A formatted register was supplied to each of the thirty (30) farmers under the study for keeping record on the experimental lactating RC cows. Date of calving, daily feed intake, weekly live weight of cows and calves, daily milk yield, post partum heat period and conception rate were recorded and collected for statistical analysis. Weighing and recording milk yield: The experimental cows were milked twice a day, between 07:30 to 09:00 hours in morning and between 15:30 to 16:30 hours in afternoon. The milk yield of cows was measured immediately after milking and recorded regularly. The milk yield in morning and afternoon were considered as daily milk yield in kg. Fat corrected milk (FCM): The fat corrected milk yield (FCM) was calculated by using the following formula: FCM = M (0.4 + 0.15 X F); Where, M = Milk yield and F = Fat percent. Collection and chemical analysis of milk: The milk samples were collected for chemical analysis. Analysis was done for fat, protein, solids-not-fat (SNF), total solids (TS) and ash contents of milk with the help of a milk analyzer machine Lacto Star (c) 2005, Funke Gerber, Firmware Rev: 3.24c, # 3510-080203. All the samples were analyzed in duplicate and mean values were recorded. Statistical analysis: The collected data were analyzed statistically by using Compare Means (CM); Means procedure of One-Way Analysis of variance (ANOVA): Post Hoc Multiple Comparisons, Equal Variances Assumed by Duncan of SPSS 11.5 for Windows statistical package.

Achievement/Findings:

The results of the present experiment showed that the farmers’ diet (63%) plus formulated concentrate diet to meet 100% requirements of lactating RC cows according to ARC (1995) {(63% +37%) = 100%} significantly increased the milk production, milk fat, and decreased the post partum heat period and service per conception. Therefore, it can be concluded that the farmers’ diet with supplementation of formulated concentrate diet to meet 100 percent requirements of lactating RC cows is a better improved feeding system and it is recommended to use for the small-scale dairy farming system.
