The research was at determining the knowledge, attitudes, and actions of farmers on the Qanun number 3 of 2016 regarding the control of productive cows and buffaloes to avoid slaughtering productive cows and buffaloes so that livestock populations are maintained. This research was conducted using a survey method for three months starting from May 2021 to July 2021. Breeders were selected using the purposive sampling method and interviews were conducted by filling out a validated questionnaire. The data analysis method used was descriptive qualitative analysis using a structured questionnaire to 110 farmer respondents with the criteria of having 2 years of experience in raising cattle, and raising female cows. The livestock population has increased since Qanun Number 3 was issued in 2016. The results of this study indicate that the level of knowledge of farmers is in a good category (72.5%), attitude is a very good category (83.2%) and action is good category (72.5%).

Primates are known to harbour different gastrointestinal parasite species that affect their survival and reproductive activity. Entamoeba histolytica infects humans predominantly as well as non-human (NH) primates causing amoebiasis. Amoebic dysentery is common amongst non-human primates in captive sites. The purpose of the study was to evaluate the risk factors associated with the prevalence of amoebic dysentery in captive NH primates of the Mefou Primate Sanctuary (MPS) in Cameroon. The faecal samples of 277 NH primates were analysed by qualitative (direct smear and evergreen kit sedimentation technique) coprology from January to July 2019. Factors such as habitat type, keepers age and level of education were assessed to evaluate their effect on the prevalence of amoebic dysentery. The prevalence of Entamoeba histolytica was 46.2% (P=0,079 and 2=18.13). E histolytica was the most predominant parasite species detected and it was present in all instances of mixed parasite infections. Amongst the NH primates positive for E. histolytica, 28 suffered from amoebic dysentery giving a prevalence of 21.9% and one of the infected primates (Cercopithecus pogonias) actually died from amoebic dysentery. The prevalence of mixed infections was significantly lower amongst NH primates living in outdoor enclosures compared to those living in other habitat types (P=0.015, 2=10.46). The rate of re-infection was significantly higher amongst NH primates under the care of keepers with the lowest (primary school) level of education (P=0.001, 2=13.09) on one hand and of older keepers (50s) (P = 0.008, 2=13.708) on the other hand. This study shows that amoebic dysentery is a cause for a major concern in the MPS. The housing conditions of the NH primates at the sanctuary, the keepers age and level of education were important factors that influenced the prevalence of amoebic dysentery. Adequate measures should be put in place to address the situation.

The COVID-19 cases in Tanjung Jabung Barat Regency, Jambi, have has risen significantly daily. This significant increase in cases illustrates that the people are less than optimal in complying with the health protocols established by the government. This phenomenon concluded that public compliance in efforts to prevent COVID-19 has a vital role in preventing the spread. This study aims to describe the level of compliance towards prevention efforts of COVID-19 in the community. We use a descriptive survey method with probability sampling techniques to obtain the data. The subjects in this study were the community of Tanjung Jabung Barat, Jambi Regency, who were17 years old with a sample size of 400 samples. Collecting data using a questionnaire in a validated form and distributed to the public via social media. The data analysis in this study is the frequency distribution analysis (univariate analysis).

Objective: We investigated the effects of a source of selenium [inorganic or nano-selenium (nano-Se)] on female V-line rabbits with or without injection of ivermectin (IVM). Material and Methods: Eighty four rabbits (12 weeks old) were randomly divided into 4 groups of 21 rabbits each with the basal diet supplemented as per the following treatments: G1 (control): inorganic Se at 0.3 mg/kg diet with no IVM injection; G2: inorganic Se with IVM injection; G3: nano-Se with no IVM injection; and G4: nano-Se with IVM injection. IVM was injected subcutane¬ously at 0.2 mg/kg body weight starting when the does were 14 weeks old and repeated weekly for five consecutive weeks. Results: Replacement of inorganic Se with nano-Se improved body weight and total body weight gain, total feed intake, average feed conversion ratio, and reproductive performance (age at puberty, number of service/conception, conception rate, number of kits/litter, and lit¬ter weight at birth). Similarly, sexual activity of does, serum estrogen levels, and serum levels of antioxidants (glutathione reduced, catalase, and malondialdehyde) increased in nano-Se-sup¬plemented groups. Ivermectin treatment in inorganic Se-supplemented groups was detrimental to growth and reproductive performance, while these parameters improved in IVM-treated and nano-Se-supplemented groups. Conclusion: Nano-Se mitigated the negative effects of IVM treatment on the growth and repro¬ductive performance of does. [J Adv Vet Anim Res 2022; 9(1.000): 128-137]

Objective: The information about risk factors for a high stillbirth rate in piglets is inadequate. Therefore, this study was conducted to determine important risk factors for an extremely high stillbirth rate in a commercial pig farm in Vietnam. Materials and Methods: This study included 628 piglets and 45 Landrace × Yorkshire sows. Data including parity number, gestation length (GL), litter size (LS), piglet's gender, stillbirth, birth order, birth interval (BI), cumulative farrowing duration (CFD), birth weight (BW), crown-rump length (CRL), body mass index, and ponderal index (PI) were collected. To deal with hierarchical data where several piglets might be born from a sow, Generalized Linear Mixed Models (GLMMs) were used to examine the association between stillbirth and investigated risk factors. Results: The stillbirth rate was 14.3%, and the incidence of stillbirth at the litter level was 68.9%. The final multivariate GLMM selected eight factors, including CFD, BI, CRL, BW, PI, GL, LS, and parity, as significant risk factors for stillbirth in the piglet. CFD >90 min, BI > 30 min, CRL [J Adv Vet Anim Res 2022; 9(1.000): 13-18]

CFD >90 min, BI > 30 min, CRL 13, and parity 5–8 were associated with increased stillbirth. The final model explained 50.1% of the variation of stillbirth, in which fixed factors explained 43.6% of the variation. Conclusion: The present study indicated that the stillbirth rate in the investigated pig farm was very high, and several factors simultaneously contributed to the situation. Selection for optimal size and shape of piglets, careful supervision of parturition, and replacement of old sows should be some of the practical approaches to reduce the stillbirth rate. J. Adv. Vet.

Objective: The study was undertaken to assess the changes in viable bacterial counts and physicochemical parameters of water used during the live transportation of Pangasius catfish (Pangasianodon hypophthalmus). The correlations between the changing patterns of these parameters were also established. Materials and Methods: Water samples were collected every 2 h interval, plated onto agar plates for assesing viable bacterial counts. Physicochemical parameters, namely, water temperature, dissolved oxygen (DO), pH, and ammonia (NH3) concentration in the water were measured with a glass thermometer, DO test kit, pH test kit, and total NH3 measurement kit, respectively. Results: The viable bacterial counts increased significantly from 0 to 2 h in all the studied chan¬nels and remained almost similar up to the end of the supply channels. The water temperature was almost stable regardless of the supply channels and transportation period at around 30°C. The DO concentration and pH level decreased, and NH3 concentrations increased gradually in all the supply channels. The viable bacterial counts were inversely correlated to the DO levels and directly associated with the NH3 concentrations of the water used during the live transportation of Pangasius catfish. Conclusions: Gradual increase in viable bacterial counts and fluctuation in some vital physicochemical parameters with the duration of transportation indicated an unfavorable environment for the survival of Pangasius catfish.

Objective: Many bacteria are involved in causing mastitis in dairy cows. Perfect identification of bacteria is crucial for the appropriate choice of drug for treatment. This study aims to find out the various bacteria that cause mastitis through the 16S ribosomal ribonucleic acid (16S rRNA) gene. Materials and Methods: A total of 150 mastitis somatic cell samples were tested with bacterial nested polymerase chain reaction (PCR) universal primers, targeting the 16S rRNA gene. The primers had both Gram-positive and Gram-negative bacterial specificities. Inflammatory cytokine interleukin (IL-10), IL-4, and interferon-gamma (IFNγ) expression genes were measured and compared in mastitis-free and mastitis-affected animals. Results: Based on the PCR, 70 (46.7%) samples showed positive results. The expression of the IL-10 gene was significantly higher (p < 0.001) in mastitis-affected cows than noninfected animals. Compared to cows diagnosed with clinical mastitis, the IL-4 and IFNγ genes were expressed more strongly in healthy cows (p < 0.0001). Conclusion: Mastitis has been linked to both Gram-positive and Gram-negative bacteria. These genes are strong predictors of mastitis in the states analyzed, as evidenced by the differential expression in mastitis and healthy conditions of the IL-4, IL-10, and IFNγ genes. The genes examined here and others will be the subject of additional research. [J Adv Vet Anim Res 2022; 9(1.000): 42-52]

Objectives: This study was designed to isolate, identify, and determine the prevalence of Aspergilli in commercial chicken in selected areas of Bangladesh. Materials and Methods: A total of 50 lung samples from suspected dead chickens, comprising broilers (n = 32) and layers (n = 18), aged between 5 days and 45 weeks, were collected from poultry farms located in the Gazipur district in Bangladesh. Fungi were primarily identified based on the colony morphology using potato dextrose agar (PDA). DNA was extracted from the suspected colonies. Aspegillus spp. was detected by genus-specific ASAP-1 and ASAP-2. Aspergillus spp. were then screened by polymerase chain reaction targeting Aspergillus flavus (FLA-1 and FLA-2), Aspergillus fumigatus (ASPU and Af3r), and Aspergillus niger (ASPU and Nilr). Results: The overall prevalence of Aspergillus spp. was 44% (n = 22/50; p < 0.05). Among the Aspergilli, A. flavus was detected in 10% (n = 5/50) of the samples. Similarly, A. fumigatus and A. niger were detected at 26% (n = 13/50) and 8% (n = 4/50) respectively. Three samples were associated with more than one fungus; two fungi (A. flavus and A. niger) were in two samples, and three fungi (A. flavus, A. fumigatus, and A. niger) were in one sample. Conclusion: Isolation and prevalence of Aspergillus spp. in commercial chicken were studied for the first time in Bangladesh. [J Adv Vet Anim Res 2022; 9(2.000): 184-190]
