ABSTRACT

Aim: The present study was designed to demonstrate the autoligation (AL) of vas deferens and the excision-ligation (EL) technique to generate vasectomized rams to reduce the complications, operative time, and price of the vasectomy techniques.

Materials and Methods: A total of 12 healthy and mature Iraqi Awassi rams were used, which divided into two groups, six rams for each one. The former group was performed the EL technique while the latter group, the AL of vas deferens technique was used.

Results: The results of the present study found that both techniques were same with the reproductive efficient examinations that mean the two techniques had same ability to close the male genital passage for teaser rams preparation. However, the methods were different with the histopathological changes, operation time, prices, and complications, which were minor in the AL of vas deferens compared with the EL technique.

Conclusion: The AL technique of vas deferens to prepare teaser animal is recommended over the EL technique due to different aspects such as cost, fewer complications, and active teaser for a long period are the main aspects of AL technique.

ABSTRACT

Aim: This study aimed to analyze the genetic variation and phylogenetic reconstruction of Indonesian indigenous catfish using mitochondrial cytochrome oxidase subunit III sequences.

Materials and Methods: A total of 19 samples of catfish were collected from seven rivers (Elo [EM], Progo [PM], Kampar [KR], Musi [MP], Mahakam [MS], Kapuas [KS], and Bengawan Solo [BSBJ]) in five different geographical locations in Indonesia. The genome was isolated from the tissue. Mitochondrial DNA cytochrome oxidase subunit III was amplified using polymerase chain reaction (PCR) with CO3F and CO3R primers. The PCR products were sequenced and continued to analyze genetic variation and phylogenetic relationship using MEGA version 7.0 software.

Results: Cytochrome c oxidase (COX)-III gene sequencing obtained 784 nucleotides encoding 261 amino acids. Sequenced COX-III gene fragments were aligned along with other catfish from Genbank using ClustalW program and genetic diversity among species was analyzed using the MEGA Version 7.0 software. Among all samples, there were substitution mutations at 78 nucleotide sites, and there were 14 variations in amino acids. Catfish from PM, KR, MP, and KS had the same amino acids as Hemibagrus nemurus (KJ573466.1), while EM catfish had eight different amino acids and catfish BSBJhad 12 different amino acids.

Conclusion: Indonesian catfish divided into four clades. BBSJ Catfish were grouped with Pangasianodon gigas, EM catfish were grouped with Mystus rhegma, and KS catfish were grouped with Hemibagrus spilopterus, while catfish MS, KR, PM, and MP were grouped with H. nemurus.

ABSTRACT

Aim: This study aimed to investigate effects of rations containing formaldehyde-protected soybean meal on meat production in Kacang goats.

Materials and Methods: Fourteen yearling Kacang bucks, weighing 15.8-19.8 kg, were arranged in a completely randomized design. The treatments included a control (PSBM0): 100% untreated SBM; PSBM50: 50% untreated SBM + 50% formaldehyde-protected SBM; and PSBM100: 100% formaldehyde-protected SBM.

Results: The goats disliked the protected SBM. Therefore, differences in their intakes were reflected in their average daily gain (ADG). The ADG and slaughtered weight of the control group were the highest, while those of the PSBM100 and PSBM50 groups were similar. The carcass weights and meat production of the control group were higher than those of the PSBM50 group, but the retained protein to the meat conversion ratio of the PSBM50 group was lower than that of the control. The carcass percentages were similar between the treatments.

Conclusion: The retained protein to meat conversion ratio of Kacang goats fed with 50% formaldehyde-protected SBM showed the lowest value, indicating that these rations efficiently produced meat in the carcass.

ABSTRACT

Aim: This study aimed to evaluate the different serological techniques for early diagnosis of acute concurrent infections with linguatulosis in the definitive host (dogs) and an intermediate host (goats). This evaluation compared between the gold standard (GS) test (GS; examination of nasal and fecal samples in dogs and examination of lymph nodes in goats), sandwich enzyme-linked immunosorbent assay (S-ELISA), and indirect ELISA.

Materials and Methods: Fifty goats and fifty dogs were examined for the presence of Linguatula serrata nymphs and adults, respectively, besides the collection of blood samples from the examined animals for serologic testing.

Results: In goats; GS, S-ELISA, and indirect ELISA showed positivity in 32 (64%), 28 (56%), and 39 (78%) samples, respectively. In dogs; GS, S-ELISA, and indirect ELISA showed positivity in 25 (50%), 25 (50%), and 30 (60%) samples, respectively. S-ELISA displayed significant higher agreement with the GS test (≥0.83) than indirect ELISA (≤0.67) in both hosts. Infection with linguatulosis showed significant relation with the age of goats and dogs and the sex of goats (p<0.05).

Conclusion: S-ELISA displayed more sensitivity and specificity for the detection of concurrent infections with linguatulosis in both dogs and goats than indirect ELISA, which could detect the prior infections. Similarly, these assays could be used for diagnosis of concurrent infections with linguatulosis in human, especially the chronic ones.

ABSTRACT

Aim: Intestinal parasites cause severe diseases at poultry farms, especially in developing countries, including Indonesia. Infections cause significant decreases in productivity at poultry farms. Ascaridia galli is a common nematode found in chickens with a prevalence of up to 92%. This study evaluates the in vitro and in vivo effects of Areca catechu crude aqueous extract (AAE) as an anthelmintic against A. galli.

Materials and Methods: In the in vitro study, already-infected slaughtered chickens were collected from local slaughterhouses in Yogyakarta. The chicken intestines were carefully examined and transported to the Parasitological Laboratory of Gadjah Mada University, Yogyakarta. A. galli was collected from the intestines and put into a Petri dish containing 0.62% saline solution. Sixty A. galli individuals were soaked in different concentrations of the AAE for 3-6 h. The number of deceased A. galli was recorded by ascertaining whether they had ceased movement using a stereo microscope. The morphological characteristics of the parasites were studied. The in vivo study used 40 female chickens that were 1.5 months old and infected with the eggs of A. galli. Approximately 3000 infective eggs were found in each chicken. There were four treatment groups; Group A served as the control and was treated with Aquadestilata, Group B was treated with 26 mg/ml of AAE, Group C was treated with 79 mg/ml of AAE, and Group D was treated with 50 mg/ml of pyrantel pamoate. The AAE was applied using a pipette for 14 days. The observed parameters include the effect of the treatments on hematology, body weight (BW), and the number of A. galli eggs within each gram of fecal matter.

Results: The AAE damaged the morphology, including the anterior end, posterior end, and vulva, of A. galli in vitro. The tegument of the anterior and posterior ends was slightly rougher, wrinkled, and damaged. The vulva and spicule ducts were irregular and indistinct. The average eggs per gram (EPG) in the untreated control increased in vivo from 1450±355.90 to 1975±325.96. The average EPG decreased from 1485±386.62 to 0±0.00 during 14 days of treatment of 79 mg/ml of AAE. The mean BW gain in the treated chickens was significantly (p<0.5) higher than the control. The treatment with 79 mg/ml of AAE increased the total erythrocyte count, total leukocyte count, hemoglobin, and packed cell volume values in the chickens.

Conclusion: AAE can cause morphological changes and subsequent death in adult A. galli in vitro and effectively decrease ascariasis severity in chickens, therefore increasing overall BW in vivo.

ABSTRACT

Aim: This study aimed to determine the potential of honey as anti-osteoporosis by evaluating its effectiveness in increasing bone impact strength and cortical thickness, through scanning electron microscopy (SEM) examination.

Materials and Methods: Forty-five female rats at 3 months of age, weighing 150-200 g were used in the study. They were placed in individual cages and adapted to food and environment for 10 days. On the 11th day, after the animals were adapted for 10 days, the animals were randomly divided into five treatment groups (n=9): Sham operation group (SH); ovariohysterectomized (OVX) group with no treatment; OVX with treatment Apis dorsata 1 g/kg BW (AD-1); OVX with treatment A. dorsata 2 g/kg BW (AD-2); and OVX with treatment A. dorsata 4 g/kg BW (AD-3). Furthermore, those nine rats in each treatment group were divided into three groups. Three of them were observed at months 1st, 2nd, and 3rd so that in each observation taken three rats in each treatment group. At the end of the study, the rats were euthanized and necropsy for taking their second femoral bone, i.e. dexter region for examining their bone impact strength, while the sinister region was used for measure the cortical thickness of the femoral diaphysis and examining their bone microarchitecture using SEM analysis.

Results: Based on results of the ANOVA test, the cortical thickness measurements of femoral diaphyseal can be seen that from month 1 to month 3 the lowest result was found in the group of rats that were OVX-I. Meanwhile, the highest result was found in the group of rats that were not OVX (SH-III). It was significantly different from the other treatment groups (p<0.05). The groups of rats were OVX with honey supplementation at doses of 2 g/kg BW had shown an increasing pattern in the cortical bone thickness from month 1 to month 3. Even on the observation of the 3rd month, the cortical bone thickness in the AD-2 (AD-2-III) group was not significantly different (p>0.05) from that in the group of rats was not OVX in month 1 (SH-I). The results of the bone impact strength measurement from month 1 to month 3 indicated that the groups of rats were OVX without the administration of honey supplements had the lowest value. The highest bone impact strength was found in the group of rats that was not OVX, but not significantly different (p>0.05) with the groups of rats that were OVX administered honey supplement with a dose of 2 g/kg BW (AD-2) and 4 g/kg BW (AD-3).

Conclusion: The supplement of honey A. dorsata at doses of 2 g/kg BW in the group of rats was that OVX can inhibit the decreasing of the cortical bone thickness and repair damage in microarchitecture to generate bone impact strength. As a result, bones are not easily broken.

ABSTRACT

Aim: This study aimed to determine the use of probiotics Bifidobacterium spp. and Lactobacillus casei as alternative antibiotic growth promoters (AGPs) to improve growth performance and business analysis.

Materials and Methods: This study used a completely randomized factorial design. The first factor was the time of administration (1, 2, 3, and 4 weeks) and the second was the use of probiotics (control without probiotics; 0.1% AGP and 0.5% Bifidobacterium spp. + 0.25% L. casei). One hundred and eighty laying hens (Lohmann strain), of 30 weeks old, were divided into 12 treatment groups, composed of five replicates, each consisting of three laying hens.

Results: The results showed that using 0.5% Bifidobacterium spp. + 0.25% L. casei in weeks 1 and 2 showed the lowest feed intake (FI) (112.11-112.19 g/day), the highest egg weight (60.28 g) in the 1st week, the lowest feed conversion ratio (FCR) (2.21-2.23), and highest feed efficiency (44.75-45.25%) for 3-4 weeks, and the highest hen-day production (86.66-86.90%) for 3-4 weeks and the most profitable business analysis (IDR. 30,353).

Conclusion: Based on the results, it can be concluded that the addition of 0.5% Bifidobacterium spp. + 25% L. casei probiotics can be used as a substitute for AGP; it can reduce the FI and FCR, increasing egg weight, feed efficiency, and hen-day production, as well as illustrating the results of the most profitable business analysis.
