Abstract

Ensuring food safety in livestock requires specific feeding technology in agriculture by using feed additives in the form of antibiotics, prebiotics, probiotics, acidifiers, hormones and enzymes. Bioactive peptides improve the health status of humans and animals. Protein hydrolysis produce peptides that are safe, quickly metabolizable, less risky for livestock products to have contaminant residue. Bioactive peptides are still bound to the original protein, so they need to be released through an enzymatic process. This research explored the potential of chicken slaughterhouse waste to produce biopeptides by hydrolyzing proteins using various proteolytic enzymes. The slaughterhouse waste included chicken feet, intestines, filleting waste and blood plasma. The proteolytic enzymes used were papain, bromelain, protease by Rhizopus oligosphorus, probiotic protease. The observed variables were dissolved protein content with and without precipitation, protein hydrolyzate content, and the degree of enzyme hydrolysis. The research was conducted using exploratory methods. The results showed that the dissolved protein content in the chicken slaughterhouse waste protein concentrate was 1,585 mg/ml (feet), 2,361 mg/ml (intestines), 1,787 (filleting waste) and 2,372 mg/ml (blood plasma). Blood plasma protein concentrate showed the highest yield among other chicken slaughterhouse waste protein concentrates, namely 0.14 mg/ml (hydrolysis of papain), 0.18 mg/ml (hydrolysis of bromelain), 0.56 mg/ml (hydrolysis of R.oligosphorus protease) 0.68 mg/ml (hydrolysis of probiotic proteases). The highest degree of hydrolysis was shown in blood plasma hydrolyzates using probiotic protease enzymes, namely 28.72%. The highest antioxidant activity was 92.92% as observed in chicken feet protein hydrolyzate which was hydrolyzed using papain. Therefore, chicken feet, intestines and fillet waste can produce protein concentrates through precipitation using ammonium sulfate, and plasma using acetone. The highest protein concentration was in blood plasma protein which also produced the highest hydrolysis from hydrolyzing blood plasma proteins with hydrolyzed probiotic protease. The highest antioxidant activity was observed in chicken feet protein hydrolyzate which was hydrolyzed using papain enzyme and incubated for 6h.

Abstract

The objective of this study was to evaluate the effect of Hibiscus tiliaceus flower extracts supplementation in concentrate on performance, nutrient digestibility and blood metabolites of Bali cattle. Sixty of male Bali cattle averaging 225 ± 09.15 kg initial body weight were used in this study. They were divided into two groups. The first group (as control) was cattle fed ammoniated rice straw and concentrate (R1) and the second group was fed as the same as the control group, but concentrate was supplemented with H. tiliaceus flower extract at 200 ppm/kg of dry matter (R2). Variables measured were dry matter digestibility (DMD), organic matter digestibility (OMD), neutral detergent fiber digestibility (NDFD), and acid detergent fiber (ADFD) using total collection method. Other variables were blood glucose and urea, average daily gain (ADG), feed conversion (FC) dan feed efficiency (FE). T-test showed that DMD, OMD, ADFD, and NDFD in the second group (R2) were higher (P<0.05) than control (R1). However, there was no significant difference (P>0.05) between performance (ADG, FC, FE) and blood parameters of urea and glucose between the groups fed diets supplemented with H. tiliaceus flower extracts and control group. There was an increase in ADG and FE on R2 (0.63 ± 0.23 kg and FE 5.54 ± 1.89) compared to R1 (0.54 ± 0.32 kg and 0.54 ± 0.32). The study concluded that supplementation of Hibiscus tiliaceus flower extracts as feed additive in the concentrate diet can increase nutrient digestibility and tend to improve the performance of Bali cattle.

Abstract

The interaction of Hibiscus Leaf Meal (HLM) and Direct-Fed Microbials (DFM) supplementation on nitrogen metabolism and rumen microbial synthesis by local sheep was investigated. Thirty six male local sheep aged ±2 years, weight 28.01±2.61 kg were fed concentrate (3% of body weight) supplemented with HLM twice a day, amoniated rice-straw (ARS) supplemented with DFM were given ad-libitum were assigned randomly to nine treatment in an experiment of 3×3 factorial design. The first factor (P) was DFM were supplemented in ARS (P0=without DFM, P1=DFMAMS, and P2=DFMRK). Second factor (W) was the level of HLM supplementation in concentrate (W0=0%, W1=0.24% and W2=0.48% of DM consentrate. The study measured variables including nitrogen digestibility (ND), nitrogen retention (NR), microbial protein synthesis (MPS), and Efficiency of microbial protein synthesis (EMPS). There were significant interaction between DFM and HLM suplementation on MPS and EMPS. However, the interaction of ND and NR was non-existent. Based on polynomial graph, the most efficient MPS was achieved on combination between DFMRK and 0.23% HLM about 8.70 gN/day. Despite the absence of interaction (P>0.05) between DFM supplementation and HLM on KN and RN, DFM supplementation significantly affected (P<0.01) Nitrogen metabolism (ND and NR). The treatment without DFM supplementation resulted the highest nitrogen metabolism (ND and NR). This study concludes that HLM without DFM suplementation positively impacted N Metabolism. Combination between 0.23% HLM and DFMRK resulted the most efficient Microbial Protein Synthesis.

Abstract

The objectives of this research were the optimalization of production and reproduction of buffalo heifers through improving feed quality based on rice straw. Twelve heifer buffaloes with body weight of 243 – 350 kg were kept in individual cages and grouped to four. Each groups were randomized to receive three treatments of A, B and C according to Randomized Completely Block Design (RCBD). A was buffalo fed only rice straw. B was buffalo fed rice straw supplemented with concentrate with a dry matter ratio of 70:30. C was similar to B but the rice straw was ammoniated using urea of 4% ensiled with 8% of cassava pulp. In-Vitro test was conducted to measure rumen fermentation product. The results showed the highest of DM and OM digestibility was achieved at C treatment, while the lowest was found at A treatment. Rumen fermentation produsts and its efficiency were the highest in C treatment. In-vivo result showed that ADG of C was higher than that of B and A. Reproductive performance characterized by frequency oestrus for 123 days were an average of 2.5, 2.8 and 4.5 times for A, B and C, respectively. The highest blood metabolite of glucose, urea and erytrocyt was found at C but the leucocyt was lowest compared to A and B. Urea treated rice straw ensiled with cassava pulp and supplemented with concentrate can improve production and reproduction performance of heifer buffaloes.
