Abstract

Effect of low voltage electrical stimulation (LVES; 45 volt, 3 amps for approx 100 sec) and CaCl2 injection on sensory characteristic of mutton were evaluated. Six mutton were divided into 3 groups slaughtered. One carcass of each group was subjected to LVES treatment within 30 min postmortem (PM). After LVES, longissimi thoracis et lumborum muscles were removed and treated: without CaCl2 injection, CaCl2 injection (200 mM, 5% w/w) 2 h and 24 h PM. Samples were stored in a vacuum pack at 1 ± 10C. Results showed that LVES could be used to improve colour of meat. CaCl2 injection, especially without LVES produced smooth mutton texture. CaCl2 injection 24 hr PM without LVES decreased meat elasticity. LVES with CaCl2 injection 2 hr PM was the best treatment to produce fresh mutton with good sensory characteristic. Key words : mutton, electrical stimulation, CaCl2, sensory characteristic

Abstract

The objective of this study was to estimate heritability of birth and weaning weights of the fighting type of Garut sheep. The data of birth and weaning weight of 175 SR (Super lambs, i.e. cross between fighting type Garut rams and selected Garut ewes) and 61 SB (Sukabumi lambs, i.e. cross between fighting type Garut rams and Sukabumi ewes) were used. The data were collected from March 2001 to August 2002. The results showed that the means of all traits of SR sheep group were larger (P < 0.01) than those of SB sheep group. Estimated heritability of birth weight and weaning weight of SR sheep were 0.67  ± 0.19 and 0.95  ± 0.16 respectively. Estimated heritability value of birth and weaning weight of SB sheep were 0.53  ± 0.33 and 0.57  ± 0.37 respectively. The heritability of birth and weaning weight were considered as high which means that the selection programme will be more effective and efficient in improving the genetic merits. Key words : heritability, birth and weaning weight, fighting type Garut sheep

Abstract

Cholin (B-hydroxyethyl-trimethylammonium hydroxide) is a constituent of phospholipids, can interfere the metabolism process that affects the growth. Sometimes cholin in a diet does not meet the animal requirement because of its low availability. The objective of the research was to study the effect of cholin chloride supplementation in the diets on broiler performance. A completely randomized design with 4 treatments and 4 replications were used in the experiment on broiler chicks reared up to 6 weeks of age. The treatment diets were R1 (control), R2 (R1 + 750 mg cholin chloride/kg diet), R3 (R1+ 1,500 mg cholin chloride/kg diet), R4 (R1+ 2,250 mg cholin chloride/kg diet). All of the prestarter diets (0-2 weeks of age) contained isocaloric (3,000 kcal ME/kg) and isoprotein (24.8% crude protein). The starter-finisher diet (2-6 weeks of age) contained 3,000 kcal ME/kg and 20% crude protein. Supplementation of 750 mg cholin chloride/kg diet (R2) increased (P < 0.01) body weight gain and final body weight. Supplementation of 1,500 mg cholin chloride/kg diet (R3) and 2,250 mg cholin chloride/kg diet decreased (P < 0.01) body weight gain, final body weight, as well as feed efficiency. It was concluded that supplementation of 750 mg cholin chloride/kg diet (containing 1,956 mg cholin/kg in prestarter diet and 1,791.3 mg cholin/kg in starter-finisher diet) yielded the best performance of the broilers. Key words : cholin chloride, broiler chickens, performance

Abstract

Dry season resulted in lower availability of ruminant feeds with subsequent effects on reduction of sheep productivity; therefore nutritive supplement may be required. The objective of this experiment was to study the effect of supplementation of catalytic substrate consisting of gelatinized sago, ammonium sulfate, Co and Zn on the sheep rumen characteristics and its microbial population. Forty lambs with an average live weight of 13 kg were divided into 8 blocks to test 5 feeding treatments. The treatments were feeding low quality forage without supplement (R1), R1 plus catalytic supplement at 10% of ration (R2), 20% (R3), 30% (R4) and a positive control treatment (R0 = R1 + soybean meal). Parameter measurements included rumen pH, ammonia, VFA and microbial population. It was observed that the rumen pH ranging from 6,06 (R1), 6,15 (R2), 6,45 (R4), 6,58 (R3) and 6,85 (R0). The rumen concentrations of ammonia were 5,83 mM (R3), 6,01 mM (R4), 6,35 mM (R2), 8,30 mM (R0) and 9,36 mM (R1) with total volatile fatty acid concentration ranging from 154, 88 mM (R1), 163,70 mM (R2), 180,89 mM (R0), 188,79 mM (R4) and 194,71 mM (R3). Population of rumen bacteri for R3 was 6,09 x 109 cell/ml, which was greater than RO (5,57 x 109 cell/ml), R1 (4,36 x 109 cell/ml), R2 (4,15 x 109 cell/ml), R4 (5,60 x 109 cell/ml), while protozoa R3 (2,59 x 106 cell/ml), was lower than RO (3,51 x 106 cell/ml) R1 (5,49 x 106 cell/ml) R2 (5,61 x 106 cell/ml) R4 (3,31 x 106 cell/ml). Catalytic supplement at 20% of ration (R3) resulted in a normal rumen concentration of ammonia and pH, and increased VFA concentration. It was concluded that catalytic supplement at 20% of ration was the appropriate level for optimal rumen characteristics.Key words : catalytic supplement, minerals, microbes, rumen, sheep

Abstract

The objective of this study was to evaluate the use of mineral soap, organic mineral and roasted soybean supplementations to improve productivity in ruminant animals. Thirty two Garut Sheep (initial body weight 22.38 ± 3.56 kg) were assigned into a randomized block design with eight treatments. Body weight was used as a block (4 blocks). Eight rations evaluated in this trial were FO: basal diet + fish oil, CO: basal diet + corn oil, CaFO: basal diet + calcium soap of fish oil, CaCO: basal diet + calcium soap of corn oil, ZnFO: basal diet + zinc soap of fish oil, ZnCO: basal diet + zinc soap of corn oil, RS: basal diet + roasted soybeans, MM: basal diet + mineral mix. The experimental diets were fed for 8 weeks. The result of the experiment showed that calcium soap improved animal growth better than did zinc soap. Daily gains of sheep fed FO (99 g/d), CaFO (114 g/d), CaCO (103 g/d), RS (105 g/d), and MM (103 g/d), diets were higher (P < 0.01) than those of sheep fed CO (86 g/d), ZnFO (88 g/d), and ZnCO (53 g/d) diets. Dry matter intake of sheep fed CO (903 g/d), CaCO (947 g/d), RS (933 g/d) diets were higher (P < 0.01) than those fed FO (820 g/d), CaFO (856 g/d), ZnFO (847 g/d), ZnCO (785 g/d), and MM (805 g/d) diets. Dry matter digestibility of CO (70%) and CaFO diet (76%) were higher (P < 0.01) than other diets. Nitrogen retention of sheep fed CaFO (11.8 g/d), RS (12.2 g/d), and MM (13.2 g/d) diets were higher (P < 0.01) than those fed FO (10 g/d), CO (10 g/d), CaCO (9.8 g/d), ZnFO (9.0 g/d), and ZnCO (9.0 g/d) diets. Organic mineral, calcium soap of fish oil, calcium soap of corn oil, and roasted soy bean supplementation increased daily gain up to 105 g/d. It was concluded that calcium soap, organic mineral and roasted soybean improved growth of sheep.Key words : soap, oil, mineral, roasted soy bean, sheep

Abstract

Most of Holstein in Indonesia were imported from European countries which have temperate climate (13-25 0C). If those Holstein were kept under high temperature and high humidity and exposed to direct solar radiation, the cattles would be experienced with heat stress, resulted in decreasing appetite, increased water intake, decreased metabolism, increased catabolism, increased heat loss through evaporation, decreased hormone concentration in blood, increased body temperature, increased respiration and heart rate and behavioral changes. To reduce the heat stress can be achieved by environment modification, such as type of animal house construction, type of roof material selected for animal house and determination of animal housing height. The improvement of environmental condition was gained for maintaining the animal heat balance in steady state, due to reducing the thermoregulatory responses (i.e heart rate, respiration rate and mean body temperature). Controlling the heat stressed animals to lower thermoregulatory activities will improve their productivity. Key words : Holstein, physiological responses, heat stress, micro-climate, environmental modification
