ENERGY DIGESTIBILITY AND TOTAL DIGESTIBLE  NUTRIENT IN DAIRY COWS GIVEN COMPLETE FEED BASED ON  CORN FORAGE. The purpose of this research  was to examine the value of energy digestibility and total nutrient digestibility in dairy cows which are given complete feed based on corn forage. 14 head of cattle with age ± 6-8 years weighing 300-400 kg were used in this study. This biological experiment used a statistical analysis of the T test with unequal variations (t-test two sample assuming unequel variance). The treatments consists of: Ra (30% Concentrate + 70% Corn forage), and Rb (30% Concentrate + 35% Corn forage + 35% King Grass). The results showed that the energy intake both of treatments(Ra and Rb) were not significantly different (P <0.05) while the energy digestibility and total digestible nutrient of the Rb treatment were significantly higher (P <0.05) than Ra treatment. It can be concluded that feed treatment using of 30% oncentrate, 35% king grass, and 35% corn forage was obtained the best energy disgestibility and total digestible nutrient values.Keywords: energy digestibility, dairy cows. corn forage , king grass

EVALUATION OF BIOLOGICAL VALUE OF DRY MATTER AND ORGANIC MATTER COMPLETE FEED BASED ON CORN FORAGE IN DAIRY COWS. This aim of this study was to determine intakes and digestibility of the dry matter and organic matter of complete feed based on corn forage. 14 FH cows weighing 300-400 kg were used in this research. The feed treatments consist of  Ra (30% concentrate + 70% corn forage), and  Rb (30% concentrate + 35% corn forage +    35% king grass). This experiment arranged in a statistical method of t-test two sample assuming unequal variance. The variables observed were intakes and digestibilities of both dry matter and organic. The results shows that the intakes of both dry matter and organic matter in the Ra were not significantly different from the Rb (P&gt; 0.05). The dry matter digestibility of Rb were highly significant different from Ra (P&lt;0.01), as well as organic matter digestibility of Rb was also significantly different from Ra (P &lt;0.05). It is concluded that complete feed consisting of concentrate, corn forage and king grass was obtained the best digestibilities of both dry matter and organic matter

KECERNAAN NDF DAN ADF RANSUM KOMPLIT BERBASIS TEBON JAGUNG PADA SAPI PERANAKAN ONGOLE

THE NDF AND ADF DIGESTIBILITY OF COMPLETE RATION BASED ON KING GRASS AND CORN FORAGE ON ONGOLE CROSSBRED CATTLE. Research has do it to evaluate intake capacity and digestibility of NDF and ADF complete feed based corn forage. Fourteen cows weighing between of one hundred eighty to two hundred and fifty kilogram were used through a biological experiment which arranged in two treatment groups, according to analyzed by T test unequal variance assumed. The treatments consisted of : Ra = 50% concentrate + 50% corn forage, Rb = 50% concentrate + 25% king grass + 25% corn forage. The variables meansured were intake capacity of NDF and ADF and digestibility of NDF and ADF. The results of T test showed that intake capacity of NDF and ADF and digestibility of NDF and ADF Rb significantly affected (P&lt;0.05) significantly than Ra. It is concluded that intake capacity and digestibility of NDF and ADF completed feed based concentrate, corn forage and king grass is better than just based on concentrate and corn forage only. Key words : digestibility, NDF, ADF, completed feed, ongole crossbreed cow
