  • Effect of Compost Tea and Harvest Age on Productivity, Nutrient Content,
           and In vitro Digestibility Cichorium Intybus

    • Authors: Rezki Amalyadi, Nafiatul Umami, Nanung Agus Fitrianto, Chusnul Hanim, Bambang Suwignyo
      Pages: 140 - 147
      Abstract: The glass house experiment involving compost tea and harvest age was conducted to investigate the effect of giving compost tea (cricket and rabbit feces) and harvesting age on productivity, nutrient content, and in vitro digestibility value of Cichorium intybus. Compost tea (CT) is an aqueous extract from compost that can correct nutrient deficiencies during crop production and protect cultivation. The research treatment consisted of two factors, namely: the age of harvest and the dose of compost tea. The administration of compost tea consisted of three kinds of doses as follows: no compost tea (P0), 200 mL of compost tea (P1), and 400 mL of compost tea (P2). The experimental plants were harvested at different age, consisting of 25, 35 and 45 days after planting (DAP). The experimental design was Factorial Completely Randomized Design (CRD) with 6 treatments and 9 replications. The data were statictically analyzed using analisys of variance, and differences among value of each treatment were tested with the Duncan Multiple Range Test. The results indicated that compost tea dose and harvesting period treatment affected (P<0.05) leaf length, fresh leaf weight, crude protein content, dry matter digestibility (DMD), and organic matter digestibility (OMD). Meanwhile, it showed not significant effect (P>0.05) on the leaf width and root length. The results suggest that the fertilization treatment of 200 mL of compost tea and 25 DAP could increase productivity (leaf length and fresh leaf weight) of chicory, nutrient content (crude protein) of chicory, and in vitro digestibility (DMD and OMD).

  • Effects of Mannanase Supplementation and Citric Acid on the Growth
           Performance of Broilers

    • Authors: Maria Patricia Arellano, Listya Purnamasari, Joseph dela Cruz
      Pages: 148 - 153
      Abstract: The study was conducted to evaluate the effects of citric acid and mannanase feed supplementation on the growth performance of broiler chickens. Three hundred twenty day-old unsexed Cobb broiler chicks from a commercial hatchery plant were used in the study. The chicks were randomly assigned to four treatment groups following a completely randomized design. The following treatment groups were used: T1: Control, T2: 3% (w/w) Citric Acid supplementation, T3: 80 ppm β-Mannanase supplementation, and T4: 3% (w/w) Citric Acid and 80 ppm β-Mannanase supplementation. The supplementation of citric acid and mannanase significantly improves the growth performance of broiler chickens. Body weight and body weight gain were significantly higher (P&lt;0.05) in the citric acid and β-mannanase combination group compared to all the treatment groups. The evaluation of feed intake revealed that T3 and T4 had significantly lower (P&lt;0.05) feed intake than the other groups. The combination of citric acid and β-Mannanase also resulted in a significantly more efficient (P&lt;0.05) feed conversion ratio. No mortality was observed during the experiment. It may be concluded that the supplementation of citric acid and β- mannanase resulted in a better performance in broilers.

  • Reproduction and Growth Performance of Kampung Unggul Balitbangtan (KUB)
           Chicken Cross

    • Authors: Galuh Adi Insani, Dyah Maharani, Stefanie Silvia, Vellina Putri Handayani, Wihandoyo Wihandoyo
      Pages: 154 - 159
      Abstract: In Indonesia, one of the sources of regional livestock genetic diversity is the kampung chicken. This study aimed to assess the development and reproductive potential of F1 Kampung Unggul Balitbangtan (KUB) crosses (KUB roosters with different types of combs crossed to layer chickens). This research was conducted at a private chicken company in Gunungkidul regency using 40 KUB roosters and 320 layer chicks. The KUB roosters were separated into four groups based on their comb types: single, walnut, and double. Each set of ten males was housed in a single cage, with a male-to-female ratio of one to eight (male and female). Observed reproductive variables included egg weight (EW), hatch weight (HW), fertility, hatchability, number of eggs, number of day-old chicks (DOCs), and number of saleable chicks. The body weight (BW) of the offspring at ages ranging from DOC, 4, 8, to 12 weeks of age is one measure of their growth characteristics. The analysis of variance using a one-way design and the DMRT test were performed to describe the difference in growth and reproductive performance across groups. As a result, each comb type revealed a significant difference in EW, HW, fertility, hatchability, egg and chick production, DOC, and saleable chick production (P<0.05). Compared to other combs, the single comb performed the best in terms of EW, HW, fertility, number of eggs, and number of DOC. The most hatchable and sellable chicks were from walnut comb. Therefore, comb size has a positive correlation with chicken reproduction and productivity. Comb type groups have no effect on BW at 12 weeks (P>0.05), while they significantly affect BW for DOC at 4 and 8 weeks (P<0.05). The rose comb shows BW at its maximum point. In conclusion, the rose comb has the biggest body weight and the single comb has the best reproductive performance in comparison to other comb types.

  • The Use of Hydrolyzed Palm Kernel Cake After Addition by Buffalo Rumen
           Fluid Enzymes on Growth Performances and Relatively Organ Weight of
           Broilers

    • Authors: Agus Budiansyah, Ucop Haroen, Anie Insulistyowati, Syafwan Syafwan
      Pages: 160 - 168
      Abstract: This study aims to utilize a sufficient amount of palm kernel cake (PKC) and buffalo rumen fluid as a source of enzymes to improve the quality of PKC that can be used in broiler feed. The study was conducted in two stages. The first stage was to test the level of buffalo rumen fluid enzyme at various doses (0.0%, 0.75%, 1.5%, 2.25%, and 3.0% (v/w) in PKC incubation to measure dry matter (DM), organic matter (OM), crude fiber (CF), and dissolved glucose total (DGT) contents as hydrolyzed PKC. The second stage was to determine the usage level of hydrolyzed PKC in broiler feed. A total of 288 DOC MB202 strains were randomly allocated to one of five treatments with four replicated cages of 12 birds in a completely randomized design. Treatments were the various level of hydrolyzed PKC as following: 0%, 6%, 12%, 18%, 24%, and 30%. The variables were feed consumption, body weight gain (BWG), feed conversion ratio (FCR), final body weight (FBW), carcass, and digestive organs weight. The level of buffalo rumen fluid enzymes had a significant effect on DM, CF, and DGT content, while it was not significant on OM. The optimum level was 2.25% and it was used in the second stage. The use of hydrolyzed PKC up to 18% was not different (P>0.05) in BWG, FCR, and FBW compared to controls. The use of hydrolyzed PKC up to 24% decreased BWG, FCR, and FBW, but feed consumption did not differ (P>0.05) compared to control. Carcass and digestive organ weight were not affected (P>0.05) by the treatment. It can be concluded that the incubated buffalo rumen fluid enzymes at a level of 2.25% could improve the quality of PKC. The use of hydrolyzed PKC could be applied up to 18% without affecting the performance of broilers

      Abstract: The study aimed at examining the hematological and biochemical profiles of Wonosobo sheep blood in various physiological conditions. There were 32 Wonosobo sheep in the various physiological conditions, including 17 ewe lamb of 1-2 months of age, 5 pregnant female sheep of 12-48 months of age at 3 months of pregnancy, 5 ewe of 12-48 months of age in second lactation period of 1-2 months and 5 ram of 12-48 months of age. Each of the sheep was put in individual sheepfold and given Pakchong-1 grass, dried kangkong, and concentrate. Drinking water was given ad libitum. Blood sample was drawn from jugular vein and put into tubes for blood hematological and biochemical analyses. The results of the study showed that total leukocyte and lymphocyte were high in young sheep, while neutrophils was high in pregnant female sheep (P<0.05). There was not any significant physiological impact on hemoglobin, MCV, MCH, MCHC, RDW, hematocrit, platelet, monocyte, eusinophil, and basophil (P>0.05). The highest ALP activity and Pi levels were found in the ewe lamb, while low creatinine was found in the ram (P<0.05). The parameter of the activities of SGPT, SGOT, LDH, calcium, kalium, chloride, sodium, magnesium, TIBC, UIBC, TS, globulin, albumin, total protein, BUN, creatinine, glucose, cholesterol, triglyceride, HDL and LDL was not affected by physiological conditions (P>0.05). It was concluded that the impact of the physiological conditions of the Wonosobo sheep caused high total leukocyte and lymphocyte in ewe lamb and high neutrophil in pregnant female sheep, the increase in the Pi level and ALP activity of the ewe lamb, and high creatinine in the ram

    • Authors: Himmatul Khasanah, Gayuh Syaikhullah, Muhammad Adhyatma
      Pages: 184 - 192
      Abstract: Sheep meat plays an important role in accomplishing balanced and healthy nutrition as a source of protein, fat, and essential micronutrients such as zinc, iron, and vitamin B12.  The amino and fatty acid composition of meat in different breeds need to be assessed to characterize and determine the development prospects of sheep that produce healthy and good quality meat. Therefore, this study aimed to investigate the phenotypic characteristics of the Sapudi and Cross Merino meat sheep including the carcass performance and meat qualities. We reared four Sapudi and four Cross Merino ewes in the same feed and environmental management for two months then slaughtered and analysed the carcass, non-carcasses and chemical meat properties. We used Bicep femoris muscle to perform proximate, amino acid, and fatty acid contents. An independent t-test was conducted to compared obtained data. Heart weight and protein content were higher in Sapudi sheep. Of the 51 fatty acids observed, we found 11 and 10 types of fatty acid in the Sapudi and Cross Merino meat, respectively. The fatty acid percentage of Sapudi meat tended to have higher value compared to Cross Merino. We also found that the two breeds have the same amino and fatty acid compositions.  The levels of glycine, arginine, serine, tyrosine, phenylalanine, lysine and threonine were statistically higher in Cross Merino than Sapudi.  In conclusion, the non-carcass, crude protein, amino acid and fatty acid level were significantly different between Sapudi and Cross Merino

      Pages: 202 - 210
      Abstract: This study aims to identify the differences in agroecological zones on changes in body weight, litter size, and profitability of Bligon goats in Bantul District, Special Region of Yogyakarta. This study involved 56 farmers consisting of 11 farmers in coastal areas (zone IV), 21 farmers in the lowlands (zone IV), and 24 farmers in hilly areas (zones I, II, and III). This study also used 120 does of Bligon goats consisting of 40 goats from each area. The farmers and Bligon goats were selected by purposive sampling technique in different agroecological zones classified based on the slope of the land. The design used was Completely Randomized Design (CRD) with the agroecological zones as a treatment factor. This study used a survey method. Data were analyzed descriptively and quantitatively using one-way ANOVA at the 5% level. The results showed that the body weight of Bligon goats from the beginning of kidding to three months or at the weaning period did not have a significant difference, and the litter size was also not significantly different. Profitability analysis using Revenue Cost Ratio (R/C Ratio) and Return on Investment (ROI) showed that farmers in coastal agroecological zones have higher profitability than those in lowland and hilly agroecological zones with a net cash flow of IDR 1,219,000, 00, R/C Ratio of 1.43, and ROI of 44.26. Based on this analysis, it can be concluded that changes in body weight and litter size of Bligon goats in different agroecological zones are the same. Based on the profitability analysis, all farmers in different agroecological zones benefit from raising Bligon goats, but the highest profitability is found in farmers in the coastal agroecological zone
