Abstract

The purpose of this experiment was to evaluate the herbage production and energy value of Suket putihan grass (Bothriochloa pertusa) harvested at different ages. The experiment was carried out following a completely randomize design with 3 treatments and 3 replications. The treatments consisted of different defoliation ages of Suket putihan grass (Bothriochloa pertusa), i.e. respectively at 40 days (BP40), 60 days (BP60), 80 days (BP80). The observed variables included the dry matter (DM) production, stem leaf ratio, In vitro digestibillity and energy value. Result showed that the defoliaton age had a significant effect (P<0.05) on dry matter production, stem leaf ratio, dry matter digestibillity and had a very significant effect (P<0.01) on the organic matter digestibillity and energy value of Suket putihan grass (Bothriochloa pertusa). The DM production of Suket Putihan grass (Bothriochloa pertusa) increased with increasing defoliation age, while its In vitro digestibility and energy value decreased due to the high stem to leaf ratio and increased harvesting time. In conclusion, the best defoliation time for B. pertusa is between 40 and 60 days after planting.

Abstract

This study aimed to determine the effect of the level of supplementation of black kabesak fruit (Acacia nilotica) on the intake and digestibility of dry matter (DM) and organic matter (OM) in Ongole cows maintained on a basal diet containing banana stems, rice bran and rice straw. This study used 3 cull Onggole cows (BW range 194-210.5 kg) aged 8-9 years. The experiment was conducted following the Latin Square Design (LSD) with 3 treatments and 3 periods as replication. The treatments were basal feed and supplemented with Acacia nilotica fruit at a level of 0% (BAN0), 0.5% (BAN0.5), 1% (BAN1) of the animal's body weight respectively. The results showed that supplementation of Acacia nilotica fruit up to 1% of body weight increased (P<0.01) the intake of DM and OM. Meanwhile, the supplementation of A. nilotica at 1% BW increased the digestibility of DM but had no effect on the digestibility of OM. The conclusion of the study was that the supplementation of black kabesak fruit (Acacia nilotica) up to a level of 1% BB could be beneficial in increasing the intake of DM and OM and the digestibility of DM in cull Onggole cows.

Abstract

This experiment aimed to investigate the effect of including Clitoria ternatea and Ulva lactuca in the complete feed on the concentration of blood metabolites of male kacang goats. Four male kacang goats were involved in this experiment arranged following a Latin Square Design with 4 treatments and 4 periods as replication. The treatments were R0= native grass hay 60%+concentrate 40%, R1= native grass hay 30%+concentrate 40%+ Clitoria ternatea 30%, R2= native grass hay 30%+concentrate 40%+ Clitoria ternatea 15%+ Ulva lactuca 15% and R3= native grass hay 30%+ concentrate 40%+Ulva lactuca 30%. Data were analyzed using analysis of variance (ANOVA) and followed by the Duncan Multiple Range Test when significant differences were found. The results showed that feeding a complete feed containing Clitoria ternatea and Ulva lactuca did not significantly (P>0,05) affect the concentration of urea, glucose and plasm total protein in the blood of male kacang goats. Therefore, it can be concluded the inclusion of Clitoria ternatea and Ulva lactuca has no effect on the concentration of blood metabolites in male kacang goats.
