Effect of Chemically Amendments of Litter on the Performance Index and Economic Parameters of Commercial Broiler Chicken

Abstract: The experiment was conducted to study the effect of chemically amendments of litter on the performance index and economic parameters of commercial broiler chickena at poultry research station (PRS), College of Veterinary Science and Animal Husbandry, Anand, Gujarat. A total of one hundred forty-four (144) straight run day old commercial broiler chicks were distributed randomly into six treatment groups. Each treatment group consisted of four replications, each of 6 chicks leading to 24 chicks per treatment. The experiment was conducted in two different seasons. Experiment-I was conducted in the winter season (WS), (December-January) and experiment-II was conducted in the rainy season (MS), (August- September) for six weeks of duration. The six treatment was divided as follows: T1- rice husk litter material (control group); T2- amendment with alum @ 90 g/sq.ft.; T3- amendment with boric acid (H3BO3) @ 24 g/sq.ft.; T4- amendment with sodium bisulphate (NaHSO4) @ 25 g/ sq.ft.; T5- amendment with commercially available probiotic product @ 1 g/sq.ft; T6- amendment with commercially available Yucca schidigera liquid solution @ 1.0 ml/ sq.ft. The litter amendment (T2 to T6) was done on the 1st, 15th, and 29th days of the experiment period. The mean production efficiency factor during experiment-I (WS) was found 285.66 ± 10.83, 335.75 ± 6.75, 318.09 ± 12.82, 323.78 ± 11.43, 291.97 ± 14.50, and 320.07 ± 12.32 in T1, T2, T3, T4, T5, and T6, respectively at the end of the experiment (42nd day). The mean production efficiency factor was significantly (P
