Abstract

Cemba (Albizia lebbeckoides [DC.] Benth.) leaf extract (CLE) was evaluated for some physical properties, antioxidant and antimicrobial activities incorporated into beef patties during cold storage. Four Formulation employed were control, butylated hydroxytoluene (BHT) 0.01, CLE 0.5, and CLE 1% (w/w). The variables measured were proximate composition, cooking parameters, pH, aw, WHC, color, total phenolic content, antioxidant capacity, DPPH scavenging activity, TBARS value, and microbial total. The data were analyzed using ANOVA one factor for proximate and cooking parameters, and ANOVA with factorial 4x5 for pH, aw, WHC, color, total phenolic content, antioxidant capacity, DPPH scavenging activity, TBARS value, and microbial total and continued with Tukey test. The results of the study showed that the addition of the CLE did not affect the proximate composition and cooking parameters of the patties. The cooked beef patties with 1% CLE showed significantly lower (P<0.05) for TBARS value, pH, bacterial total (mesophilic and psychrophilic) compared to 0.5% CLE and controls. The total phenolic content, antioxidant capacity, scavenging activity of CLE 1 % were significantly higher (P<0.05) than 0.5% CLE and controls during the cold storage period (0, 7, 14, 21, and 28 days). Addition of both 0.5 and 1% CLE in cooked beef patty reduced bacteria total. The addition of 1% CLE had equivalent to BHT 0.01% effect in retarding lipid oxidation. In conclusion, the CLE 1% was effective to retard lipid oxidation and inhibit bacteria growth of cooked beef patties.

Abstract

   The aim of this research was to examine the microbiological quality of calf starter pellet added with fermented cabbage waste after stored for 0, 4, and 6 weeks. The materials used in this research consisted of cornmeal, rice bran, soybean meal, molasses, mineral mix, and fermented cabbage waste. This research used Completely Randomized Design with 4 treatments and 3 replications. The mixed calf starter pellet consisted of 100% calf starter and 6% of fermented cabbage waste, and then stored for 0 weeks (P0), 2 weeks (P1), 4 weeks (P2) and 6 weeks (P3). The observed microbial qualities were the total lactic acid bacteria and the presence of gram positive and negative bacteria in the mixed calf starters. The total lactic acid bacteria were analyzed descriptively, while the presence of gram bacteria was analyzed with analysis of variance followed with Duncan’s test. The result of this research showed that an increase in storage time would result in lower lactic acid bacteria population, while the gram-positive and negative bacteria was not significantly affected. The research concluded that 6-weeks stored calf starter pellet added with 6% of fermented cabbage waste could maintain its lactic acid and gram-positive bacteria population, while also reducing its gram-negative bacteria population as well.

Abstract

The Thyroglobulin (TG) and Leptin (LEP) genes are two candidate genes that widely used for molecular selection to improve carcass traits in beef cattle. This research was carried out to identify the genetic characterization of TG and LEP genes from 47 heads of Pasundan cows at West Java using PCR-RFLP method. Research shows that TG gene of Pasundan cattle is monomorphic with C allele as the dominant allele (1.00). However, LEP gene of Pasundan cattle is polymorphic with C allele as the dominant allele (0.98) and T as the rare allele (0.02). The polymorphic informative content (PIC) and numberof effective allele (ne) values in the LEP gene in the animal studied were 0.04 and 1.04 respectively. It was concluded that TG/BstYI and LEP/Sau3AI gene in the present study can not be used as molecular selection in Pasundan cattle. These results are important as the basic information for preparing the molecular selection program in the future.

Abstract

The purpose of this research was to determine the effect of heat stress on thermoregulation, haematology, and productivity of Holstein Friesian (HF) dairy cows raised in different elevations. A total of 63 HF in a normal lactation period were used in this study. The research was conducted for 3 months during dry season in three different areas, which were at Pondok Ranggon (97 m.a.s.l) which categorized as a lowland, Ciawi (576 m.a.s.l) which categorized as a lower-upland, and Lembang (1241 m.a.s.l) which categorized as an upland. Observation on microclimate aspects which includes environmental temperature (Ta), relative humidity (RH) and Temperature-Humidity Index (THI) was done by recording each variable for every 2 hours starting from 08.00 to 16.00 WIB. The thermoregulation analysis was done based on the given physiological responses which consisted of the skin temperature (Ts), rectal temperature (Tr), body temperature (Tb), heart rate (Hr), respiratory rate (Rr), Heat Tolerance Coefficient (HTC), plasma cortisol level and haematological profile observation. The Ta, Rr, and THI measurements showed that in the lowland and lower-upland, the HF experienced moderate heat stress, while the HF raised in the upland area experienced less heat stress. The results showed that the dairy cows which raised in lowland had the highest HTC, Tr, Ts and Tb (P<0.05) and lowest Hr (P<0.05). All of the physiological and haematological parameters in the three study area showed a normal value.Furthermore, the erythrocyte, Hb and PVC concentration in a lowland raised HF were higher (P<0.05), while the plasma cortisol levels were not significantly different. The milk production of the observed dairy cows in different elevations was significantly different (P<0.05), with the highest milk yields, were found in the upland raised HF (13.1±3.52 kg), followed by the lower-upland (11.3±4.73 kg) and lowland (7.0±3.36 kg). In general, all of the HF raised in different land elevations was exposed to heat stress during dry seasons, even though the cows showed the ability to physiologically adapt and cope with the conditions.

Abstract

The aim of this study was to evaluate the effect of different IgY concentrations on the production, reproduction and immunity of Sentul chicken. This research used 20 month-old Sentul chickens which consisting of 10 chickens with high IgY concentration and 10 chickens with low IgY concentration Parameters observed included prelayer performance (feed consumption, weight gain, feed conversion, morbidity and mortality), layer performance (feed consumption, egg production, egg weight, feed conversion, hatchability, morbidity and mortality), and immunity at chicks (IgY concentration of eggs and chicks serum). The experiment was conducted as a completely randomized design. The treatments were high and low IgY concentration. All treatments were repeated 10 times. The data obtained were analyzed using the SAS program t-test. Morbidity and mortality were analyzed descriptively. The results of this research indicated that the prelayer period, chickens with high IgY concentration had a higher performance than chicken with low IgY concentration. This is caused by about 30% chickens with low IgY were in sick condition for approximately seven days. Further, the layer period showed that the chickens with high IgY concentration had lower production performance than the chicken with low IgY concentration. The study concluded that chickens at low IgY concentrations are susceptible to exposure to antigens that lead to decreased productivity. In normal conditions hens, Sentul with high IgY concentration resulted in low production. The observation of chicken immunity showed that concentration of IgY from chicks and eggs did not differ between hens with high IgY concentrations and hens with low IgY concentrations.

Abstract

 This study was done to determine the effect of Roselle extract level (Hibiscus sabdariffa), and the wheat flour and mocaf flour ratio, as well as the interaction between the Roselle extract level and the wheat flour and mocaf flour ratio on the chemical, physical, and antioxidant activity of chicken sausage. The ingredients used were chicken meat, wheat flour, mocaf flour, Roselle extract, skim milk powder, and spices. Roselle extract levels were 0, 4, and 8% (v/w of total dough) and ratio of wheat flour : mocaf flours were 100:0, 50:50 and 0:100. Parameters observed included chemical composition (moisture, protein, and fat contents), physical properties (pH value and tenderness), and antioxidant activity of chicken sausage. Data were analyzed by analysis of variance of 3x3 factorial and continued by Duncan's new multiple range test test. The results of statistical analysis showed that Roselle extract level gave a significant effect (P<0.05) on moisture content, pH value, and antioxidant activity of chicken sausage. Ratio of wheat flour : mocaf flour gave a significant effect (P<0.05) on protein content,  tenderness and antioxidant activity of chicken sausage. There was no interaction between Roselle extract level and the wheat flour : mocaf flour ratio on the physicochemical properties and antioxidant activity of chicken sausage. The conclusion of this study is the addition of Roselle extract upto 8% will increase moisture content and antioxidant activity, but it decreases the pH value and tenderness of chicken sausage. Subtitution of wheat flour with mocaf flour will reduce protein content, tenderness and antioxidant activity of chicken sausage.

Abstract

This research aimed to investigate the rabbit meat hydrolysate potential as an angiotensin-converting enzyme (ACE) inhibitor. Indonesian local rabbit meats were used in this study. The research was conducted in Department of Animal Product Technology, Faculty of Animal Science, Universitas Gadjah Mada, from August 2016 to February 2017. The local rabbit meats were hydrolyzed by pepsin, trypsin, and pancreatic. The obtained hydrolysates were then analyzed to identify the water-soluble protein content. The molecular weight of the hydrolysates were also confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The ACE inhibitory properties of the hydrolysates were analyzed in vitro. The results showed that pepsin, trypsin, and pancreatic hydrolysis showed a significant effect on the water-soluble protein content of rabbit meat (p<0.05). The water-soluble protein of rabbit meat hydrolysed by pepsin, trypsin, and pancreatic were 9.41, 7.66, and 9.75 mg/mL respectively. The molecular weight of the rabbit meat hydrolysate were increased from 10 to 43 kDa; 17 to 43 kDa; and 10 to 43 kDa, after hydrolysed by by pepsin, trypsin, and pancreatic respectively. Furthermore, the ACE inhibitory properties ) of the hydrolysed rabbit meat by pepsin, trypsin, and pancreatic were 439, 170, and 380 μg/mL, respectively. The rabbit meat hydrolysate showed a potential to be ACE inhibitor after hydrolyzed with pepsin, trypsin and pancreatic. Moreover, it also showed a promising potential to be used as bioactive components in different pharmaceutical applications. The highest ACE inhibitory capability was showed on trypsin hydrolysis with the total of 65.45% and 170 μg/mL ACE inhibition
