Abstract

Heat stress in the tropics is a limitation to production efficiency of broiler chickens (BC), as early chick mortality is aggravated by sharp fluctuations in brooding temperature, high relative humidity and environmental temperatures. The balance of acid-base in broilers could be enhanced by supplementing diets or water of BC under heat stress with electrolytes. However, information on the ideal dietary electrolyte balance (DEB) of BC under heat stress at pre-starter and starter phases is scanty. Therefore, a study was carried out using a total of 300, one-day-old Arbor Acre chicks that were randomly allotted to six dietary treatments [210 (T1), 240 (T2), 270 (T3), 300 (T4), 330 (T5) and 360 (T6)] mEq/Kg DEB, in a completely randomized design. Birds were reared at pre-starter phase (PSP) of 0–14 days and starter phase (SP) of 14 - 21 days, under the temperature-humidity index of 24.97 - 35.19. Feed intake (FI, g/bird), body weight (BW, g/bird), body weight gain (BWG, g/bird), feed conversion ratio (FCR), and mortality (%) were monitored. Data were analysed using descriptive statistics and ANOVA at α0.05. Birds on T3 had lower FI (409.28 ± 34.79) compared to T5 (460.82 ± 31.94), but did not differ significantly from birds on T1 (443.16 ± 18.18), T2 (437.20 ± 25.61), T4 (426.17 ± 19.59), and T6 (431.66 ± 45.24) at PSP. The BW and BWG of chicks were not significantly affected at PSP and SP. The FCR of birds on T3 was significantly improved at PSP (1.38 ± 0.09) and SP (1.30 ± 0.04). A dietary electrolyte balance of 270 mEq/kg improved performance of pre-starter and starter chicks.
