Optimizing growth: A starter ration study for IPB D-1 chicks

Abstract

Poultry nutrient requirements are significantly influenced by both growth stage and breed. However, specific starter ration guidelines are lacking for the IPB D-1, a hybrid combining 75% local and 25% broiler genetics. This critical period demands protein-rich diets to achieve optimal growth. To address this gap, a study was conducted to investigate the impact of varying protein levels (22% and 20%) in starter rations for unsexed, day-old IPB D-1 chicks (n = 400). The chicks were divided into two dietary groups and housed in open and semi-closed housing systems (10 replicates of 10 chicks each). Feed and water were provided ad libitum for 2 weeks, and monitoring of feed intake, weight gain, and feed conversion ratio (FCR) was performed. Chicks fed the 22% protein diet displayed significantly higher (P<0.05) feed intake and weight gain compared to the 20% group. Additionally, a noticeably improved FCR was observed. Housing type significantly affects (P<0.05) these measured parameters, with the semi-closed housing system being superior. This study highlights the enhanced response of IPB D-1 chicks during the starter phase to a higher protein content ration and a semi-closed housing system.
