Abstract/ Executive Summary:

A total of 90 day old as hatched Cobb 500 broilers had free access to a pre-starter diet (crumble) from day old to 14 days of age. A starter diet (pellet) was provided up to end of the experiment. Broilers were allocated to 0 (control), 0.2 or 0.4% of potassium chloride (KCl) in drinking water and reared up to 500, 1000 or 1500 g target weights to vary the rearing period. The study was aimed at to assess broiler performance (growth and meat yield) altered by KCl supplementation in drinking water in a hot and humid summer. KCl had no effect (p>0.05) on growth and meat yield characteristics of broilers except feed conversion (p<0.05) at different target weights. In most of the growth and meat yield parameters, KCl had no interactions (p>0.05) with target weights. However, 0.4% KCl level slightly improved feed intake, growth rate and performance index. Increasing level of KCl tended to increase most of the major meat yield characteristics. On the basis of results of this study, it may be concluded that, supplementation of KCl in drinking water in summer improved the feed conversion of broilers. However, further experiments using several doses of KCl may be conducted to confirm the appropriate doses of supplementation.

Objectives:

To assess broilers growth and meat yield altered by KCl supplementation in drinking water during summer.

Methodology:

An experiment designed with 90 day old as hatched Cobb 500 broiler had free access to a pre-starter diet (crumble) from day old to 14 days of age. A starter diet (pellet) was provided up to end of the experiment. The pre-starter diet contained ME 2950 kcal/kg, CP 21.00, CF 5.00, Ca 1.00, available phosphorus 0.45%. Whereas, the starter diet contained ME 3000 kcal/kg, CP 20.00, CF 5.00, Ca 0.95, available phosphorus 0.45%. Broilers were allocated to 3 levels of potassium chloride (KCl) and 3 replications for each level of KCl. Ten broilers constituted each replication. Broiler diets supplemented with 0, 0.2 and 0.4% potassium chloride were supplied throughout the experimental period. The records were kept on initial live weight, growth, feed intake, feed cost and survivability growing them up to some given target weights (TW); 500, 1000 and 1500 g. All the broilers had exposure to a continuous lighting of 23h and 1h dark period every day. Rice husk at a depth of 5cm was used as litter material. All broilers had free access to continuous drinking facilities. Floor space for each broiler was 900 cm². The live weight of broilers was monitored for each pen to reach some given TW. A routine vaccination was performed to all broilers against New Castle and Gumboro diseases. From each replication, 3 broilers weighing average of pen weights were randomly selected for further analysis. The selected broilers were fasted for about 8 hours before slaughtering. They were defeathered, eviscerated, dressed and removed unnecessary organs and debris. The meat components of the carcass were stripped out to show the overall effects on meat yield and their comparison among treatment combinations. The major meat yield characteristics recorded were dressed yield, total meat, breast meat, dark meat, thigh meat, drumstick meat, wing meat and trimmed meat. The meat yield related data were on feather, neck (length and weight), blood loss, liver, heart, head, spleen, abdominal fat, gizzard, length and weight of elementary tract. Dissection of carcass was recorded for each broiler was performed by the procedure. All data either recorded or calculated were for a 3(KCl) x 3(TW) factorial experiment in CRD with multiple observation per cell (replication). All the meat yield data were converted into percentage of individual live weight prior to statistical analysis. A GENSTAT computer package was used for statistical analysis.

Achievement/Findings:

Supplemental KCl in drinking water had no impact (p>0.05) on feed intake, growth rate, survivability and performance index except feed conversion (p<0.05). In most of the growth parameters, KCl had no interaction with TW though increasing KCl level tended to slightly increase growth performance of broilers. The major and vital meat yield characteristics did not differ among broilers on supplementation of KCl in drinking water. Moreover, KCl levels did not interact with target weights to influence any growth and meat yield characteristics. However, increasing KCl had a tendency to slightly increase the broiler performance. Overall results on growth and meat yield may be slightly increased at 0.4% level of KCl in comparison with control. Such an assumption was made from the slight beneficial effect of 0.4% KCl on broiler performance. It may be recommended that either 0.4% KCl or higher may be useful in broilers. So, future experiment could be undertaken with different doses higher than 0.4% KCl.
