Abstract

The purpose of this experiment was to evaluate the effect of soursop leaf meal on characteristics of  blood and meat  fat of male Tegal ducks. This study used completely randomized design. The study consisted of four treatments, namely: feed without supplementation of soursop leaf meal, feed with 5% soursop leaf meal, feed with 10% soursop leaves meal, and feed with 15% soursop leaf meal. Each treatment was 5 replications and each replication consisted of five ducks. The treatment given to duck for 5 weeks started from 4 to 10 weeks of age. Data were analyzed by Analysis of Variance (ANOVA) continued by orthogonal polynomial test. The results showed that soursop leaf meal supplementation in feed had no significant effect on levels of blood triglycerides, cholesterol, and LDL as well as meat triglycerides and cholesterol, but it affected levels of HDL significant (P<0.01), ie increase HDL levels. It can be concluded that soursop leaf meal supplementation in male Tegal duck feed by 8.36% showed the highest blood HDL levels (99.89 mg/dl), however soursop leaf meal supplementation up to 15% did not affect levels of blood triglycerides, cholesterol, and LDL as well as levels of meat triglycerides and cholesterol of 9 weeks male tegal duck.

Abstract

An experiment was aimed to assess the use of the legumes as a source of protein feedstuff and levels of protein-energy synchronization (PES) index in the diet of dairy cattles on volatile fatty acids (VFA) and methane (CH4) profile. The research was applied in In vitro techniques used a completely randomized design (CRD), with factorially pattern (2x3), the first factor was the two species of legumes (Sesbania and Leucaena) and the second factor was the three level of the PES index (0.4, 0.5, and 0.6), there were 6 treatment combinations and each was 4 replicates. The results showed that interaction between legumes with PES index was not significantly affected (P>0.05) on all variable. Legumes was not significantly affected (P>0.05) on all variables and PES index was significantly affected (P<0.05) on propionate, A:P ratio, and methane. The study concluded that the use of turi and lamtoro leaves combined with the protein-energy synchronization index (PES) at medium level (0.5) could increasing the production of VFA, especially propionate, suppressing A:P ratio and decreasing methane production.

Abstract

The protein-energy  synchronized  (PES)  index-based  rations  can  optimize microbial  protein  synthesis  (MPS)   and   affect   enzyme   activity   and  macronutrient digestibility of ration in rumen fluid. This study aimed to examine the in vitro effect of a ration based on PES index on macronutrient digestibility and enzyme activity in rumen fluid. The research was conducted experimentally, consisting of 4 treatment rations with different  PES  indexes  (R1:  0.55;  R2:  0.6;  R3:  0.65;  R4:  0.7).  Each  treatment  was repeated 5 times, so there were 24 experimental units. The material used was the rumen fluid of the Jawa Randu Goat, which was taken at the Sokaraja Slaughterhouse shortly after  the  goat  was  slaughtered.  Each  ration consisted  of  napier  grass,  river  tamarind, coconut  meal, soybean  dregs,  rice  bran,  cassava  waste,  and  mineral  mix.  The  results showed  that  the  PES  index  significantly  affected  (P<0,01)  the  digestibility  of  protein (A),  fiber  (B),  and  fat  (C),  as  well  as  the  activity  of  protease  (D)  and  cellulase  (E) enzymes.  Theorthogonal  polynomial  test  showed  that  the  PES  index  has  a  quadratic effect on all test parameters with the following equation: A (Y= -1229.5X2 + 1540.6X -457.57; R2= 0.75), B (Y = -800.95X2+ 955.86X -264.51; R² = 0.75), C (Y = 868.92X2-1038.2X + 325.1; R2= 0.81), D (Y = -41.4X2+ 51.697X -14.982; R² = 0.77), and E (Y = -4.8538X2+  5.927X -1.6241;  R²  =  0.84).  The  protein-energy  synchronized  index-based rations increased the in vitro of macronutrient digestibility (protein, fiber, and fat) and enzyme activity on rumen fluid at a medium index level (0.6-0.63).
