Effect of liver stimulants on performance and carcass characteristics of Vanaraja chicks

An experiment was conducted to investigate the effects of herbal liver stimulants like Liv-52 Protec, Liver-Up and non-herbal Livozyme-Fe liquids on performance of Vanaraja chicken. A total of 450 straight run day old chicks of Vanaraja were wing banded and randomly distributed in to four groups. Group I, II and III were respectively given Liver-up, Livozyme-Fe and Liv-52 Protec @ of 10 ml/day/100 chicks in drinking water from day one to the six weeks of age and group IV was served as control without any supplementation. All the groups were fed with the layer chick starter ration and were vaccinated against Ranikhet disease and infectious bursal disease. Significantly higher (P<0.05) body weight gain (0–6 weeks), ready to cook meat yield in groups treated with Livozyme-Fe and Liv-52 Protec and numerical improvement in- Liver-up group was observed. In groups II and III there was significant reduction (P<0.05) in relative weight of liver. Numerical improvement was observed in all treated groups for feed consumed/unit body weight gain and livability. Both herbal and non-herbal liver stimulants namely Liv-52 Protec and Livozyme-Fe enhanced the performance of Vanaraja chicken and there were no significant differences among herbal and non-herbal liver stimulants on the performance of Vanaraja chicken.
