Abstract

Penelitian bertujuan untuk menduga model kurva pertumbuhan ayam kampung unggul balitnak (KUB). Ayam yang digunakan sebanyak 100 ekor dibagi menjadi lima kelompok masing-masing yang diberi ransum yang terdiri atas lima tingkat energi dan protein yaitu ; R1 (15,08% dan 2755 Kkal/kg) R2 (17,04% dan 2754 Kkal/kg), R3 (19,03% dan 2752 Kkal/kg), R4 (15,05% dan 2951 Kkal/kg) R5 (17,02% dan 2948 Kkal/kg). Ayam dipelihara selama 12 minggu, data yang dikumpulkan adalah bobot badan dan pertambanan bobot badan. Data yang diperoleh dibuat tebarannya, kemudian dilihat nilai koefisien determinasi (R2 ) dan standar error (Se). Hasil penelitian diperoleh bahwa : (1) tingkat energi dan protein dalam ransum yang diberikan tidak berpengaruh nyata terhadap pertumbuhan ayam KUB; (2) kurva pertumbuhan ayam KUB sampai umur 12 minggu mengikuti model Morgan Mercer Flodien (MMF) dengan persamaan y x x x 46,1 246,1 = 101)(52,31( )18, + ( 2669 69, ) 1/( + 101 18, ) (3) laju pertumbuhan untuk ayam KUB sampai umur 12 minggu masih cenderung naik.

Abstract

AbstractChicken growth will be showing a curve with certain mathematic model. The aim of this research was to predict growth curve model of kampung super garut chicken Fed With Pasak Bumi Meal (Euricoma longifolia Jack). This research used descriptive eksperimental method with 100, divided in five groups. Every groups fed with Pasak Bumi Meal in five categories is R0 (0%), R1 (0,025%), R2 (0,050%), R3 (0,075%) and R4 (0,100%). Chickens reared for 12 weeks, the collected data is body weight and body weight gain. Scatter plots data is used for estimated determination coefficient (R2), correlation coefficient (r), and standard error (SE). The results showed that; (1) addition of pasak bumi flour in ration at level 0,075% in ration resulted growth performance optimal; (2) The Gompertz model with the formula of  Y = 1965.2 exp (-3.7890e-0.1456t ) was the best model with coefficient determination (R2) of 99.94%, coefficient of correlation (r) of 99.97%, and standard error (SE) of 16.01%. (3) growth rate until 12 weeks ages still increase.
