  The objective of this study was to evaluate the differences in growth performance and carcass characteristics of Bali cattle subjected to oil palm integration and two different feedlot finishing systems (basal vs. high energy). Eighteen, 24-30 months old male Bali cattle were involved in this study. The animals were randomly allotted into 3 feeding groups: Integration (INT), (n = 6 animals), Feedlot A (FA) with basal energy (n = 6 animals) and Feedlot B (FB) with high energy (n = 6 animals). The animals assigned to the integration system were allowed to graze on the native forages and legumes available under the oil palm plantation. The basal energy diet consisted of 5 kg Palm Kernel Cake (PKC) pellets + ad libitum corn stover and the high energy diet which consisted of 5 kg Palm Kernel Cake (PKC) pellets + ad libitum corn stover + 400 g calcium soap of palm oil fatty acids (Megalac®, Volac International Limited, UK) were fed to the animals in FA and FB, respectively. The feeding trial was conducted for 120 consecutive days excluding 3 weeks of adaptation period. The present data suggest that some of the growth parameters and carcass traits in Bali cattle can be enhanced through the feedlot finishing system.

  The study was carried out in an attempt to assess meat quality of Bali cattle finished in 3 different systems. Twenty one bulls were selected from an existing herd under an oil palm plantation and randomly assigned to 120 days of feeding in; Integration-INT (n = 8), basal energy Feedlot-F (n = 6) and high energy Feedlot-FB (n = 7) System. All animals were humanely slaughtered at a commercial abattoir. Samples of Longissimus Dorsi (LD), Supra Spinatus (SS) and Semi Membranosus (SM) muscles were collected and prepared accordingly for the determinations of pH, cooking loss, shear force and color (L* and a*) values. The animals finished on Integration (INT) demonstrated higher L* values (p<0.05) in SS muscle and lower L* values (p<0.05) in both LD and SM muscles. Lower cooking losses (p<0.05) were observed in LD and SM muscles from the INT group. However, there was no difference in pH, a* (redness) and shear force values among the treatments and these were consistently shown in all three muscles. The results from this study demonstrate the influence of finishing system on Bali cattle meat quality.

  The objective of this study was to evaluate the impact of supplementing inorganic Selenium (Se), Iodine (I) and combination of both on their concentrations in serum, skeletal muscle and organs of 24 local Kacang crossbred meat goats. Four dietary treatments of six goats each were randomly allotted to basal diet without supplementation (background only) as control (T1), basal diet + 0.6 mg Se kg-1 DM (T2), basal diet + 0.6 mg I kg-1 DM (T3) or basal diet with combination of 0.6 mg Se + 0.6 mg I kg-1 DM (T4) for 100 consecutive days. Serum samples were collected at days 0, 30, 60 and 95 for the determination of Se and I concentrations. Semitendinosus (ST) muscle, liver and kidney were also collected, vacuum packaged and stored frozen until assayed for the Se and I levels. The levels of I and Se in the serum of supplemented groups (T2, T3 and T4) were significantly higher compared to control (T1). In comparison with the control animals (T1) I and Se concentrations in the ST muscle, kidney and liver were also higher (p<0.05) in the supplemented groups. The results demonstrated the potential of Se and I dietary supplementation employed in this study to increase the concentrations of both elements in the serum, muscle, liver and kidney of goats.
