Abstract

THE USE OF A COMPLETE FEED BASED ON CORN FORAGE ON  THE DIGESTIBILITY OF CRUDE FIBER AND NITROGEN FREE EXTRACT OF THE FRIES HOLLAND DAIRY  COWS. This study aims to determine of the use of complete feed based on corn forage on the digestibility of crude fiber and nitrogen free-extract (NFE) of the Fries Holland (FH) dairy cows. This research used 14 dairy cows aged 7-8 years with a bodyweight of 300-400 kg. This study used an experimental method with t-test analysis (unequal diversity) consisting of 2 treatments with 7 replications. This study was arranged in two treatment groups according to t-test (assuming unequal varience). They consisted of Ra = 70% corn forage + 30% concentrate and Rb = 35% corn forage + 35% king grass + 30% concentrate. The variables observed were crude fiber consumption, NFE consumption, crude fiber digestibility and NFE digestibility. T Test analysis results showed that the consumption of crude fiber treatment of Ra (2.07 kg/head/day) was not significantly different (P>0.05) with Rb treatment (2.10 kg/head/day) while NFE consumption showed no significant difference (P>0.05) between Ra (3.36 kg/head/day) and Rb (3.46 kg/head/day). The digestibility of crude fiber showed a very significant difference (P<0.01) between Ra (70.31%) and Rb (78.15%) while NFE digestibility showed no significant difference (P>0.05) between Ra (87.97%) and Rb (90.28%). Based on the results of this study it can be concluded that feeding with concentrate of 30%, corn forage of 35% and king grass of 35% has better in increasing digestibility of crude fiber than just consisting of concentrate of 30%  and corn forage of 70% in dairy cows (FH).Keywords: digestibility, crude fiber, NFE, Fries Holland cows

Abstract

THE EFFECTS OF OFFERING KING GRASS (Pennisetum purpupoides) AND CORN  STOVER ON DRY MATTER AND  ORGANIC MATTER OF ONGOLE CROSS BREED STEER CALVES. A research has been conducted to evaluate the effects of offering king grass (Pennisetum purpupoides) and corn stover as ingredients for ration formulating on dry matter and organic matter digestibility of ongole cross breed steer calves. Five ongole cross breed steer calves with about 100 kg body weight were used in this experiment. Latin square design  with 5 tereatments was used. The treatments were rasio of king grass and corn stover; R1 = 100% king grass, R2 = 75% king grass + 25% corn stover, R3 = 50% king grass + 50% corn stover, R4 = 25% king grass + 75% corn stover, R5 100% corn stover.  The variables measured were dry matter and organic matter digestibility. Analysis of variance showed that there were no significant effect of treatments on dry metter and organic matter digestibility. Averages of dry matter digestibility during experiment ranged 56.27% - 59.48%. The highest was 59.48% for R5 (100% corn stover) and the lowest was 56.27% for R1 (100% king grass). Averages of organic matter ranged from 87.64% to 88.72%. The highest organic matter digestibility was on R4 (25% king grass + 75% corn stover) and the lowest organic matter digestibility was on R2 (75% king grass + 25% corn stover). It can be concluded that the best nutritive value was at combination of 25% king grass + 75% corn stover on dry matter and organic matter digestibility of ongole cross breed steer calves. keywords: king grass, corn stover, digestibility, dry matter, organic matter
