Abstract

This study was carried out at Bali Cattle Breeding Centre (BPTU Sapi Bali) in Pulukan, Jembrana, Bali from March to November 2012. The aims of study were to estimate the heritability and genetic response to selection for yearling weight in Bali cattle. Records on 350 yearling weights of Bali cattle born from 2007 to 2011 at the Bali Cattle Breeding Centre were used in this study. The results showed that the average coefficient of variation for yearling weight of Bali cattle was 18.28%, the estimated heritability (h2) was 0.42 ± 0.19, and the selection intensity was 0.92.  This value ??indicated that selection for this trait might improve the genetic quality of Bali cattle particularly in their liveweight at one year old.  Estimation of genetic response (Rg) obtained in this study was 9.02 kg.  The average generation interval in this population was 4.48 years.  Therefore, response per year (Ry) for yearling weight in this breed of cattle was 2.01 kg.  Based on this response per year, prediction for response in the year 2010 and 2011 were 6.03 kg and 12.06 kg respectively.  It was concluded that the heritability estimate of yearling weight in Bali cattle was categorized high and selection for this trait responded effectivelly

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 study was carried out to determine the effect of probiotics supplemented in low protein diets on performances of broiler aged 2-6 weeks. The design used was a completely randomized design (CRD) with three treatments and six replications. Each replication consisted of three broiler chickens aged two weeks with homogeneous body weight. The treatments were a standard ration containing 20% crude protein as a control diets (A), the ration with 18% crude protein content (B), and a diet with 18% crude protein content with a probiotic 0.20% Saccharomyces spp supplemented (C). Feed containing 2900kcal/kg metabolic energy and water were provided ad libitum. The results showed that the decrease of crude protein content rations of 2% units lower than the recommended standard rations (treatment B) were significantly reduced (P<0.05) on final body weight, body weight gains, and feed efficiency compared both with the control and treatmens C groups. In contrast, there were increased significantly different (P<0.05) on the amount of abdominal-fat. Supplementation of probiotic 0.20% Saccharomyces spp in the ration C were increased on body weight gains and feed efficiencies significantly different (P<0.05) compared with treatment B.  In contrast, there were decreased significantly (P<0.05) different on abdominal-fat and blood serum cholesterol contents of chicken.  It was concluded that supplementation of probiotic 0.20% Saccharomyces spp culture in ration with protein content 18 % resulting the same of broiler performance aged 2-6 weeks compared to the control. Supplementation of probiotic 0.20% Saccharomyces spp cultures in the ration can decrease abdominal fat and blood serum cholesterol contents of broiler aged 2-6 weeks.

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

The use of waste as component material ration provides benefits that do not compete with humans, is relatively inexpensive and can reduce environmental pollution. The purpose of this study were to determine the benefits and the impact of the provision of water hyacinth (Eichornia crassipes) from polluted waters as feed suplement on the performance of Landrace pigs. This research used completely randomized design (CRD) with 4 treatments and 4 replications. A total of 16 Landrace pigs with an average live weight of 20 kg were used in this study. The four treatments are: (A) pigs received rations without water hyacinth, (B) pigs received rations plus 2.5% water hyacinth, (C) pigs received rations 5% plus water hyacinth and (D) pigs received rations 7.5% water hyacinth plus. Growth of pigs, feed intake, feed efficiency, feed digestibility and nutrient digestibility, carcass composition and quality, fat content, and the content of heavy metals (Pb and Cd) in the meat, intestines, kidneys and liver were evaluated in this study. The results showed that the use of water hyacinth from polluted waters up 7.5% in the feed had no effect on the growth of pigs (P> 0.05). They tends to improve feed intake and consumption of organic matter, as well as increasing their feed conversion but the difference significant (P> 0.05). Digestibility of dry matter, organic matter and nutrient but were not significantly different by tend to decrease with the increasing the use of water hyacinth originated from polluted waters in the ration (P> 0.05). Digestibility of dry matter, organic matter digestibility and nutrient digestibility were also tend to decrease by increasing the use of water hyacinth originated from polluted waters in the ration but not significantly different (P> 0.05). The use of water hyacinth up to 7.5% in the ration did not affect to the percentage and pieces of carcass weight (P> 0.05). The content of heavy metals (Pb and Cd) in meat, kidney, liver and small intestine of pigs received rations containing water hyacinth originated from polluted water, still below the limit of safe consumption. It was concended tha the use of water hyacinth from polluted waters as pig feed material to the level of 7.5% did not significantly affect the performanceof Landrace pig in tern of growth carcass weight, carcass percentage and meat quality
