Abstract

An experiment was carried out to study to the role of urea lime mixture in concentrate containing cassava on the rumen fermentation of the etawah crossbred goat through in-vivo experiment. A randomized block design (RBD) consisted of 4 different rations and 4 replicates was used in this experiment. Atotal of 16 etawah crossbred goats with initial body weight ranging from 12.4 - 19 kg were aranged in to 16 pens experiment. Four feed treatments (A, B, C and D) were offered to four groups of four goats. The first treatment (A) was 50% elephant grass 50% concentrate (without cassava urea lime) as control diet, the second treatment (B) was 50% elephant grass 50% concentrate (without cassava, with 4% urea and 2% lime), the third treatment (C) was 50% elephant grass 50% concentrate (with 25% cassava, 4% urea and 2% lime), and fourth treatment (D) was 50% elephant grass 50% concentrate (with 50% cassava, 4% urea and 2% lime). Ration was composed based on standard requirement of 15 kg body weight goat with 75 g daily weight gain. Results of This study showed that the concentration of NH3, VFA, propionic acid, and protozoa rumen population on treatment A, B, C, and D were significantly different (p<0,05). It can be concluded that Utilization of 4% urea and 2% lime without cassava in concentrate increased N-NH3 level of rumen fluid, but level of N-NH3 rumen fluid on goat fed with 4% urea and 2% lime in concentrate contain 25 and 50% cassava was not increase, compared to thoset fed controled (treatment A). Propionic acid level and rumen protozoa population could be increased through urea lime and cassava addition in concentrate.

Abstract

The aim of this research was to observe the effect of giving difference levels concentrate on NNH3, VFA production and in vitro of dry matter and organic matter digestibility. Completely Randomized Design (CRD) was used in this study with four treatments and four replications, i.e. 75% concentrate + 25% forage (60% king grass + 40% glyricidia) (A); 60% concentrate + 40% forage (60% king grass + 40% glyricidia) (B); 45% concentrate + 55% forage (60% king grass + 40% glyricidia) (C); and 30% concentrate + 70% forage (60% king grass + 40% glyricidia) (D). The result of this study showed that the NNH3 concentration was highest in treatment A, which was 13.60 mM. VFA concentration was higher in treatment C, which was 118.40 mM. Dry matter digestibility and organic matter digestibility was higher in treatment A, which were 59.71 and 60.27%. It is concluded that the giving of concentrate with containing urea, lime and cassava from 30 to 75% has non-significant (P>0.05) effect on NNH3 and VFA level in every treatments. Giving higher level of concentrate will be increase dry matter and organic matter digestibility

Abstract

An experiment was carried out to study temperature humidity index (THI) and physiological responses of local rabbit offered different level of energy and protein feeds and housed in two cage systems.  A split – plot design consisted of two main plot : under ground shelter  and battery housing system and four diets as sub plot with different energy and protein level. The result show that, under ground shelter cage produced lower (P<0.05) THI than the battery cage (26.17 vs. 27.69).  The lower THI in under ground shelter cage than battery cage causing physiological responses better to the rabbits.  Diets with different energy and protein level did not give significant effect on THI, skin temperature and rectal temperature (P>0.05).  It was observed that there is a significant interaction (P<0.05) between cage system and ration on respiration rate.  Diets did not  have any significant effect (P>0.05) on respiration rate  of the rabbit housed under ground shelter cage. But converse was true for battery cage. Diets containing 2800 kcalME/kg and 18,50% crude protein causing significantly higher (P<0.05) respiration rate  than  other diets.  It was concluded that under ground shelter cage give  a better responds than battery cage.  Diets  differing  in energy and protein level did not affect temperature-humidity index. Further,  diets with 2800 kcalME/kg and 18.50% crude protein gave less physiological impact  than  those diets containing 2600 kcalME/kg and 17% crude protein, 2400 kcalME/kg and 15.50% crude protein, 2200 kcalME/kg and 14% crude protein.

Abstract

A study on growth rate of male rabbit fed different levels of fermented coffee pulp was carried out at Gulingan village, Mengwi, Badung regency, Bali province from August to October 2013. A Randomized Block Design (RBD) with five treatments and eight replicates in each treatment was used in this experiment.  The treatment were diet  without coffee  pulp (R0),  diet with 10%  unfermented coffee pulp (R1), diet with 20% unfermented coffee pulp (R2), diet with 10% fermented coffee pulp (R3), and diet with 20% fermented coffee pulp (R4). Each treatment consisted of 8 male five week old local rabbits as replication. Variables observed were final body weight, weight gain, feed intake, water consumption, feed efficiency, dry matter, energy and protein digestibility. The results showed that rabbits  given ration with 10% fermented coffee pulp (R3) revealed has higher dry matter energy and protein digestibility. Further, that had highest final body weight, weight gain and highest feed efficiency. From the result of the experiment can the  concluded that the use of 10% fermented coffee pulp in the diet produced the highest performance (P<0,05)  compared to other treatments. The use of fermented coffee  pulp 10% could be recommended to farmers for substituting rice brand in rabbits diets.

Abstract

This experiment was conducted to determine the protein and energy requirement for maintenanceand growth of bali cattle. The experiment used randomized completely block design (RCBD), whichconsisted of five treatments and three weight groups as block. The initial body weight of male bali cattlewas 198.67-207.00 kg. The treatments were five rations which composed with different protein andenergy content as follows: ration A with 15.42% protein and 4020 kcal GE/kg DM, ration B with14.74% protein and 3750 kcal GE/kg DM; ration C with 13.11% protein and 3790 kcal GE/kg DM ;ration D with 10.33% protein and 3920 kcal GE/kg DM, and ration E with 10.58% protein and 3530 kcalGE/kg DM. The variables measured were nutrient intake and as well as the calculation of the energy andprotein requirement. The results showed that dry matter and energy intake were not significant different,but the highest protein consumption was on A treatment and the lowest was on E treatment (0.77 vs 0.52kg/d). Requirement of protein and energy for maintenance was 8.23 g/ W0.75/d and 137.85 kcal/W0.75/d,while requirement of protein and energy for growth was 345.25 g/kg body weight gain and 3753.31kcal/kg body weight gain. Total protein and energy requirements of growing bali cattle could becalculated with the formula PRt = 8.23 W0.75 + 345.25 ?W g / d and ERt = 137.85 W0.75 + 3753.31 ?Wkcal/d, where: PRt is total protein requirements; ERt is total energy requirements; W is body weight and?W is weight gain ).

Abstract

This study was carried out to increase the content of Omega-3 (EPA and DHA) on beef by feeding bali cattle with supplemented lemuru fish oil in Molamix concentration. A Randomized Complete Block Design was applied consists of 3 treatment diets and 4 weight groups as replication. There were tweleve Bali cattle used at range weigh of 248-277 kg. The cattle randomly allocated into 3 treatments fed with elephant grass + concentrate without fish oil supplementation as control (RKMBI10); elephant grass + concentrate with lemuru fish oil supplementation 5% (RKMBI5); and lemuru fish oil supplementation 10% (RKMBI10). The study showed that lemuru fish oil supplementation decreased dry matter consumption (BK) in accordance with the increase of concentration energy content. Fish oil supplementation produces ALA in beef fat RKMBI0 at 0.18%, RKMBI5 at 0.20% and RKMBI10 at­ 0.14 % which was not significantly different. While the EPA content in beef fat RKMBI5 at 0.07% higher than the beef meat RKMBI0 at 0.05%, and RKMBI10 at 0.04 %. RKMBI5 beef content of DHA. In contrary, 0.06 % was not found on RKMBI0 and RKMBI10 beef. The amount of omega-3 content in each 100 g of RKMBI5 at 1.16 mg and RKMBI10 at 1.75 mg significantly (P<0.05) higher than RKMBI0 at 0.60 mg. It can be concluded that fish oil supplementation in molamix lemuru concentrate decreased ration palatability which lead to decrease dry matter consumption. However, fish oil supplementation significantly increased the amount content of omega-3/100g on bali cattle.

Randomized Block Design consisted of four feed treatments with 3 block of weight live as replicates were used in this study. The initial weight of male bali cattle used range between 181-265 kg. These four treatments based on dry matter (DM) were: A (45% elephant grass + 0% rice straw + 15% glyricidia + 10% calliandra + 30% concentrate); B (30% elephant grass +10% rice straw + 20% glyricidia + 10% calliandra+ 30% concentrate) ; C (15% elephant grass +20% rice straw + 25% glyricidia +10% calliandra + 30% concentrate)  and treatmen D (0% elephant grass + 30% rice straw + 30% glyricidia  + 10% calliandra+ 30% concentrate) . Variables which were measured: nutrient consumption, balance energy, energy retention, weight gain and FCR. The results showed that Dry Matter and energy intake were highest in treatment C, but not significantly different (P>0.05) compare with the others. Weight gain was significantly the highest (P<0.05) in treatment C and FCR significantly the lowest (P<0.05). Energy retention treatments B, C and D did not show significant differences (P> 0.05) but in the A treatment significantly the lowest (P<0.05). Heat production significantly the lowest (P<0.05) in treatment D compared to treatment A and C. It could be concluded that the ration C gave lowest FCR and had higest weight gain compared to others treatment.

Abstract

Artificial insemination services on Bali cattle in Badung Regency have not been optimum up to 2012 since the number and distribution of the inseminators have not been evaluated in relation to the cows population in the villages of this regency. The aims of this study were to create a map of Bali cow population and locations of inseminators in order to improve the artificial insemination services in this regency. Data of Bali cattle population base on the result of census in 2011 were used in this study and interview on the inseminators was carried out to find out the existing problems in the field. Mapping of the location of the inseminators and cow population in the villages of Badung Regency was done using Geographic Positioning System (GPS). The results of the survey showed that inseminators were not well distributed according to the number of cows available in each village or district of Badung regency, and this regency still needs a total of 22 inseminators to optimize the application of artificial inseminators. This was shown by the map of inseminators and cows population in the villages of Badung Regency. Other factors such as skill of the inseminators were needed to be improved, addition of inseminator facilities particularly motorcycles were needed to be added since 57.69% of the inseminators have not got motorcycles for their duties in the field. It was concluded that the map of the inseminator locations and population of cows in Badung regency as well as addition of motorcycles and improvement of the inseminator skills to optimize the implication artificial insemination program were needed in this regency.
