The use of Chaya leaf powder in feed diet on growth performance and carcass weight in Tapao Kaew chicken

Abstract

The aim of this experiment was to study the use of Chaya leaf powder in feed diet on feed intake, growth performances in Tapao Kaew chicken breed. The experimental design was 2×4 Factorial in Completely Randomized Design (2×4 Factorial in CRD) with the animals were conducted into two groups of age chicken (A1: 2 weeks, A2: 4 weeks) and four groups of dietary feed and was three replicates with five chicken per replicated. Treatments using Chaya powder at 0, 5, 10 and 15 percent in the feed (B1, B2, B3 and B4, respectively). As the results, the final weight was no difference among the animals and feed groups. However, the average dairy gain (ADG) and feed consumption rate (FCR) was no significant difference between the chicken groups and feed groups (p>0.05). The feed intake in animal A1 was lower than the animal A2 in feed intake, while the feed group (B2, B3 and B4) were higher than the control group (B1) (p<0.05). In addition, the animal A1, A2 and feed groups were not different (p>0.05) with average daily gain. Percentage of carcass weight, lower wing, hips, including meet, shins, head and neck, and blood were not different in the 4 feed groups and the 2 groups of animals. The feed cost per gain was higher in animal A2 than animal A1 and using Chaya in the feed. Therefore, using Chaya leaves can be used at 5-10 percent in feed ratio without negative affecting on feed intake and growth performance in Tapao Kaew chicken.
