Abstract

Flamboyant (Delonix regia) is a plant that thrives all year round. This study aims to evaluate the nutritional content of flamboyant leaves processed with different processing methods. The study took in the Animal Feed Nutrition Laboratory of State Agricultural Polytechnic of Kupang from June to August 2022. The experimental design used was a Completely Randomized Design (CRD) with 5 treatments and 5 replications. The treatments tested were F1: flamboyant was dried in the shade for 5 days, F2: flamboyant was soaked in water for 4 hours, F3: flamboyant was soaked in a solution of rubbing ash for 4 hours, F4: flamboyant was ammoniated for 3 weeks, F5: flamboyant was fermented for 3 weeks. The results showed that the treatment tested had a very significant effect (P<0.01) on the content of organic matter, crude protein and crude fiber but had no effect (P>0.05) on the content of dry matter and crude fat. It can be concluded that the water immersion can increase the organic matter content, ammonia treatment increases the crude protein content and reduces the crude fiber content of flamboyant leaves.

Abstract

This study aims to determine the growth performance of female Native chickens at the grower phase (6-12 Weeks) after being given arginine-lysine in low protein feed. This research was carried out from May to August 2022 at the Kampung Chicken Housing, Sion Women's Farmer Group, Sasi Village, Kefamenanu. The material used is 80 Native chickens aged 6-12 weeks with an average body weight of 400 g. The research method used is a complete randomized design. Chickens were randomly placed for 5 treatments and 4 replications, each replication consisted of 4 bird. The treatment given was P0 (control feed + 0.60% arginine + 0.52% lysine + 18% CP); P1 (control feed + 0.70% arginine + 0.61% lysine + 17% CP); P2 (control feed + 0.80% arginine + 0.70% lysine + 16% CP); P3 (control feed + 0.90% arginine + 0.79% lysine +15% CP); P4 (control feed + 1.00% arginine + 0.88% lysine + 14% CP). Variables observed were body weight gain, feed intake and feed conversion ratio. Data analysis using variance analysis and Duncan test. The results showed that the average body weight gain at treatments P0, P1, P2, P3 and P4 were 71.67±3.75; 84.69±3.55; 105.63±3.71; 105.46±7.15; and 94.38±3.50 g/bird/week, respectively. Feed intake were 277.41±15.95; 324.98±13.20; 401.13±15.10; 397.19±30.00; and 363.30±12.06 g/bird/week. Feed conversion ratio were 3.87±0.02; 3.84±0.01; 3.80±0.02; 3.77±0.03; and 3.85±0.01. Analysis of variance showed that the treatment had a significant effect on body weight gain, feed intake and feed conversion ratio of female Native chickens at the grower phase (P<0.05). It was concluded that the use of the arginine-lysine increases body weight gain, feed intake and decreases feed conversion ratio of female Native chickens at the grower phase (6 – 12 weeks). The level of 0.80-0.90% arginine + 0.70-0.79% lysine can streamline the use of feed crude protein by 2-3% from 18% to 15-16% and provide maximum results on the performance of female Native chickens at the grower phase.
