Abstract/ Executive Summary:

The study was conducted to find out the performance of broiler birds fed different levels of potato meal (PM). The levels of potato meal in the different treatment rations were control 0, 5, 10, and 15 g/kg, respectively. Dietary levels of PM did not affect live weight at 7, 21, 28, 35 and 42 days of age. However, live weight of broiler differed significantly (p<0.05) among different levels of PM in the diet at 14 days of age and increasing level of PM had a tendency to decrease live weight between 7 and 14 days of age. Feed intake increased linearly with the increasing level of dietary PM (p<0.05) up to 35 days of age followed by a decline at 42 days of age. At 14 days of age, feed intake in control diet and 10g PM diets were similar and intermediate, it was highest in 15g PM and lowest on 5g PM diet. However, feed intake did not differ (p>0.05) among different levels of PM in diet at 21, 28, 35, and 42 days of age. Feed conversion ratio (FCR) decreased between 7 and 14 days of age with the least conversion observed at 15 g/kg PM level. FCR didn’t differ significantly (p<0.05) among different levels of PM in diet. Mortality did not alter due to the increasing levels of PM regardless of age of broiler. Dietary PM did not modify the dressing yield, breast meat, thigh meat and other carcass traits. Feed cost in different dietary PM groups were more or less similar, whereas total production cost per kg broiler were increased in 10 % Potato Meal than control (p<0.05). However, sale price (Taka/broiler) and sale price (Taka/kg broiler) were more or less similar in all treatments. Profit per broiler and per kg broiler were reduced as the PM level increased in the diet. It was therefore concluded that use of potato meal at 5 to 15g/kg diet may not be suitable for growth and profitability in broiler production.

Objectives:

To find out the performance of broiler birds fed different levels of potato meal (PM).

Methodology:

The experiment was conducted with 96, straight run Cobb 500 commercial broilers during 14-42 days of age at Bangladesh Agricultural University (BAU) Poultry Farm, Mymensingh. Materials and Methods Potatoes were collected from a local market. After proper washing and cleaning of soil and dust, skins were removed and the flesh was cut in desirable pieces (2mm). Then pieces of raw potato were spread on clean polythene for sun drying. The experiment was conducted in an open sided a gable type tin-shed house. The house was partitioned into 16 pens using wire-net (38cm height) where a group of 6 broilers were randomly allocated to each pen. Each pen was 257cm x 64cm and was allotted for 6 broilers. Therefore, floor space for each broiler was 3433 cm Polythene bags were used for short term storage of potato meal.These bags also helped to prevent spoilage from insect and fungus formation. Approximately 20kg PM was used. 2. One trough (90cm x 11.5cm x 6cm) feeder and one pot drinker with a capacity of one litter were provided in each pen up to 42 weeks. The chicks were collected from a local market (dealer) in Mymensingh district. The experimental rooms in the broiler house were properly washed and cleaned by using tap water and disinfected by using disinfectant Iosan. The chicks were collected from a local market (dealer) in Mymensingh district. The experimental rooms in the broiler house were properly washed and cleaned by using tap water and disinfected by using disinfectant Iosan. They were equally and randomly divided and assigned to four dietary treatments (0, 5, 10 and 15g/kg PM) with four replications for each treatment. At the end of the experiment, 16 broilers; one broiler (straight run) from each plot (4 diets x 4 replications), weighing average of pen weight were selected to determine meat yield characteristics. To facilitate processing, all birds had their feed and water withheld 12 hours prior to killing. After complete bleeding, the slaughtered broilers were immersed in water heated to 51-55°C for 120 seconds in order to loosen the feathers of the carcass. Final processing was performed by removal of the head, shanks, viscera, oil gland, kidneys and lungs of the carcasses. All recorded and calculated data were statistically analyzed using analysis of variance technique by a computer using a SAS statistical computer package program in accordance with the principles of Completely Randomized Design. The LSD were calculated to compare variations among diets where ANOVA showed significant differences.
