PENGARUH INTENSITAS PEMOTONGAN TERHADAP PRODUKTIVITAS Indigofera zollingeriana
Get PDFTHE EFFECT OF DEFOLIATION INTENSITY ON PRODUCTIVITY OF Indigofera zollingeriana. This research aims to know the effect of defoliaion intensity on productivity (fresh production, dry weight production, proportion of leaves and stems) and to know the defoliation intensity with optimal productivity of forage Indigofera zollingeriana. This research was conducted in December 2019 until March 2020. It consisted of defoliation intensity at 75cm (T75), 100cm (T100), 125cm (T125), and 150cm (T150). The design used in this experiment is Completely Randomized Design. The variables in this research were 1. fresh production leaves and stems; 2. dry weight production leaves and stems; 3. the proportion of leaves and stems dry weight production of forages Indigofera zollingeriana. The results showed that the difference of intensity defoliation had a significantly effect (P<0,01) on productivity (fresh production, dry weight production, proportion of leaves and stems) forage Indigofera zollingeriana. Defoliation intensity 75 cm have significantly (P<0,01) fresh and dry weight leaf of Indigofera zollingeriana than hight defoliation 125 cm and 150 cm. Intensity defoliation 125 cm have significantly (P<0,01) leaf-stem ratio of Indigofera zollingeriana than any other. It conclude that intensity defoliation 125 cm have highly productivity.

PENGARUH BOBOT TELUR HASIL PERSILANGAN ITIK MOJOSARI DAN ALABIO TERHADAP DAYA TETAS, BOBOT DAY OLD DUCK (DOD), DAN MORTALITAS
Get PDFEFFECT OF EGG WEIGHT FROM CROSSBRED OF MOJOSARI AND ALABIO DUCK BREEDS ON HATCHABILITY, DAY OLD DUCK WEIGHT AND MORTALITY. This study was conducted to determine the effect of egg weights as a result of the crossing between Mojosari and Alabio breeds on hatchability, day old duck (DOD) weight and mortality. This study used 90 eggs from crossbred of Mojosari and Alabio duck breeds. This study applied a completely randomized design. Significant differences were tested using the Duncan test. A complete randomized design involved three treatments with six replications at each treatment using five eggs at each replication. Treatments of egg weights was applied on differences in egg weights as follows, Egg weights A1 of 60 g-64 g, Egg weights A2 of 65 g-69 g and egg weights A3 of 70 g-75 g. The duration of this study was 28 days using a semi-automatic hatching machine. The research variables were day old duck weight (DOD), hatchability and mortality. The results of this study showed that treatments did not affect significantly the hatchability, DOD and mortality (P> 0.05). Therefore, it can be concluded that varying weights of eggs as results of crossing between Mojosari and Alabio had the same effect on the hatchability, DOD weight and mortality of the generation.Keywords: Duck egg weights, day old duck weight, hatchability, mortality

Get PDFDIGESTIBILITY OF CALCIUM AND PHOSPHORUS COMPLETE FEED BASED ON CORN FORAGE IN ONGOLE CROSSBREED COWS. Research was conducted to evaluate digestibility of calcium and phoshorus ongole crossbreed cows based on Corn Forage. Fourteen cows were used in this experiment, one and a half to two years old by weight of one hundred eighty to two hundred and fifty kilograms. this research was using experimental method, the data were analyzed by T test (Unequal Variance Assumed). Consisting of two replications and seven treatments used. The treatment used was : Ra = 50% concentrate+ 50% corn forage, Rb = 50% concentrate+ 25% king grass + 25% corn forage. The variables measured were feed calcium and phosphorus consumption, calcium and phosphorus digestibility. The results of analysis T test showed that intake capacity of calcium significantly affected (P<0.05) between Ra (31.49 gram/animal/day) and Rb (31.02 gram/animal/day) while calcium digestibility of treatment Rb (84.92%) higher significantly than Ra (77.70%). The results of analysis T test showed that intake capacity of phosphorus Rb (31.45 gram/animal/day) significantly affected (P<0.01) than Ra (30.52 gram/animal/day) and phosphorus digestibility Rb (88.39%) significantly affected (P<0.01) than Ra (83.94%). Based on the research result can be concluded that the complete feed consisting of 50% concentrate, 25% king grass (Pennisetum purpupoides) dan 25% corn forage increase digestibility of calcium and phosphorus ongole crossbreed cows.Key Words: Ongole crossbreed cattle, complete feed, digestibility, calcium and phosphorus

Get PDFEVALUATION 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> 0.05). The dry matter digestibility of Rb were highly significant different from Ra (P<0.01), as well as organic matter digestibility of Rb was also significantly different from Ra (P <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

Get PDFTHE PREFERENCE OF FOOD TYPE AND THE INFLUENCE ON WEIGHT GAIN OF WHITE TAILED RAT (Rattus xanthurus) IN EX-SITU BREEDING. White tailed rats (Rattus xanthurus) is one of the endemic species of  North Sulawesi that has the status of near threatened. The method used in this study is the method of observation. This research was conducted to provide information about the most preferred type of food and its effect on body weight gain, food consumption and the efficient use of white rat (Rattus xanthurus) so that they can be utilized in animal breeding business.  The results showed that the type of food most preferred by the White Tailed Rat (Rattus xanthurus) female was papaya fruit 55.62 gr / head / day while males preferred the banana 49.28 gr / head / day. Weight gain in males is higher 17.79 g / head / day compared to females 10.09 g / head / day lower with 60 gr / head / day feeding. The highest efficiency of food use is found in males, this condition can be interpreted that the amount of consumption is enough to contribute to the weight gain of white tailed rats (Rattus xanthurus). The results of this study it can be concluded that the white tailed rat (Rattus xanthurus) prefers papaya fruit compared to other fresh foods.Keywords: Preference, Weight gain, White-tailed ra

Get PDFSTUDY ON BEHAVIOUR OF THE LONG TAIL MONKEY (Macaca fascicularis) OBESE IN INDIVIDUAL CAGE. This study was designed to obtain information of development behaviour the obesity of long-tailed monkey (Macaca fascicularis) fed with high energy obes diet. The need of obese monkeys highly to model byomedis obesity. Obesity is now a universal problem that needs to be explored and studied. Therefore, the objective of this research was to develop obese adult male monkeys with high energy food for 12 months and monitoring their behaviour. Fifteen adult male monkeys 6-8 years old with the weight of between 4-5 kg were divided equally into three groups. The first group was body weight average 4.50 kg, the second group was body weight average 5.00 kg; and the third group was body weight average 4.75 kg. The results showed that body weight gave a significant effect (P <0.01) on daily behaviour and also gave a significant effect (P<0.01) on fed behaviour frequently,drink behaviour, agonistic behaviour, grooming behaviour, and locomotion behaviour .Keywords: Behaviour frequently, Long-tailed monkey (Macaca fascicularis), Obesity
