The abundance of agricultural products often causes environmental problems. The utilization of agricultural waste from carrots can reduce both the feed cost and environmental pollution and become a source of vitamin A for the health of the native chicken. The study aims to analyze carrot (Daucus carota L.) waste juice on native chicken performance. It was conducted from April to July 2019 at Pandu experimental field in North Minahasa Regency. The practical method used was a completely randomized design with four replications. The experimental livestock used in the study was 80-day-old chickens of native chicken. The concentration of carrot juice during the study was as follows: 100% drinking water without carrot juice (W0), 80% water drinking + 20% carrot juice (W1), 60% drinking water + 40% carrot juice (W2), and 20% drinking water + 80% carrot juice (W3). Observed variables included feed intake, body weight gain, feed conversion ratio (FCR), and mortality rate. The results showed that carrot waste juice significantly impacted the body weight gain, feed conversion rate, and 0% mortality rate during the 8 weeks. The concentration of 20% drinking water + 80% carrot juice (W3) with the feed intake ratio of 1.608 g, body weight gain value of 775.63 ± 301 g, and the FCR of 2.1 ± 0.06. However, the consumption ratio did not differ among treatments. The addition of carrot waste juice, as much as 80%, in the drinking water of native chickens showed an increase in body weight compared to other treatments. In conclusion, the current study showed that treatment of carrot waste juice has a significant effect on body weight in 8 weeks of maintenance. Meanwhile, the feed intake ratio of carrot waste juice treatment has no real effect. There was no dead chicken (0%) in the present study. The carrot waste juice can be used in chicken drinks 40–80% by paying attention to the balance of energy content and feed proteins used to grow chickens. |
