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

An experiment was carried out to determine the energy balance and performance of bali cattle fed different forage compositions. 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

Become of the aims of this study was to determine the effects of sugar-salt solution given to pigs during periods of slaughtering delay as an effort to decrease weight losses of main physical components of their carcasses. The study used randomized complete block design and a 3 x 4 factorial treatment array. The treatments were three levels of sugar-salt solution, i.e. g0 (had no access to the sugar-salt solution or provided with plain water only), g1 (treated with 150 g sugar + 15 g salt solution), and g2 (treated with 300 g sugar + 30 g salt mixture), and four levels of slaughtering delay i.e.  l0 (without slaughtering delay), l1 (one day of slaughtering delay), l2 (two days of slaughtering delay), and l3 (three days of slaughtering day). The sugar-salt mixture was diluted in 1 litter of water. Results of the study showed that there was no interaction between provision of the solution and slaughtering delay on weight of main physical components (meat, bone and fat) of the carcass. As a separate factor, however, provision of the solution or slaughtering delay alone has significantly (P<0.05) affected weight of the carcass components. Prolonged slaughtering delays significantly lowered (P<0.05) weights of dissected meat and subcutaneous fat ranging from 0.9 to 13.5%, and from 14.1 to 29.3%, respectively. Weights of bone, inter-muscular fat, and skin, however, were not significantly affected (P>0.05) by the slaughtering delays. Moreover, provision of the sugar-salt solution significantly (P<0.05) decreased the weight losses of meat and subcutaneous fat so that their weights were higher by 21.6 and 12.9% compared to control, respectively. But, the solution had no affect (P>0.05) on bone, intermuscular fat, and skin weights. It could be concluded that the provision of sugar-salt solution is a importen attempt to reduce losses of meat subcutaneous fat of pig carcass when fewcess have to be delayed.

Abstract

This research was carried out to study the response of lekang baby turtles or Day old Turtles (DOT) fed tuna fish compared to shrimp for three months from hatched. The result of the study hopefully might support their conversation since this species was reported as endanger species. Completely randomized design was used in this experiment using five feed treatments (A, B, C, D And E) which were 100% tuna, 75% tuna + 25% shrimp, 50% tuna + 50% shrimp, 25% tuna + 75% shrimp and 100% shrimp respectively. Statistical analysis showed that the average weight gain of baby turtles was significantly different among the all treatments where the fastest growth was showed by baby turtles fed 100% tuna (treatment A), while the slowest was the baby turtles in treatment E which were fed 100% shrimp. The baby turtles weight gains in treatment A, B, C, D and E were 0.79, 0.74, 0.63, 0.59, 0.52 g respectively. However, their feed consumption and feed conversion ratio mostly were not significantly different between the all treatments except for feed conversion ratio between treatment A and treatment E where baby turtles that fed 100% tuna more efficient than those fed 100% shrimp. This result was related to protein and energy consumption between the treatments and also related to protein and energy retention between those five treatments. The highest protein and energy consumption and also the protein and energy retention was shown by baby turtles fed 100% tuna and the lowest was shown by baby turtles by 100% shrimp. It was also found that width of the front flippers has close correlation with body weight (R2 = 0.74 and r = 0.86) of the baby turtles.  These flippers have an important function for swimming and diving because the baby turtles live in the sea. It might be concluded that lekang baby turtles grew faster up to three months old when were fed tuna fish compared to shrimp. Their efficiency in using feed for growth similar between the all feeding treatments. There was a close relationship between the size of flippers and body weight of lekang baby turtles. Therefore, management of lekang baby turtles by feeding them with tuna fish up to three months of age might support conservation program of the turtle particularly lekang turtle as endanger species in Indonesia.

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

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 ).
