Twenty one non pregnant multiparous anestrous goats with an average body condition score (BCS = 2.5) were selected. After the last PG injection, all the goats were exposed to three fertile bucks. They were observed to be in standing estrus. For further confirmation of copulation, a vaginal cytology test was performed for the presence of sperm inside the vaginal smear. Serum estradiol (E2) peaks were also estimated by using radioimmunoassay in estrus goats. MAP sponge efficiency with respect to estrus induction was found to be superior (57%) as compared to the rest (Ovsynch14 and PG 0%) (p< 0.05). Post PG standing estrus time in ovsynch and MAP groups was recorded as 48 h and 44 ± 12 h, respectively. The double PG group totally failed to show standing estrus. E2 peak levels ranging from 11-38 pg/ml in ovsynch and 10–25 pg/ml in the MAP group were observed in estrus goats. This study found the MAP sponge protocol most efficient for inducing estrus in anestrous goats.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89834859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introducing innovation in beef cattle farming has brought new changes in the livestock sector. Hopefully, it can generate a high income among farmers and brighten the Malaysian economy. However, introducing innovations such as assisted reproduction technology, biosecurity and intensive rearing require more significant effort from all parties, including farmers, extension agents and the government. This paper aims to identify beef cattle farmers' challenges in adopting innovations to improve beef production. Process of identifying, screening and eligibility is essential in producing an extensive literature review paper. From these processes, nine articles were found as the most relevant for this review article. The financial problem, communication failure and inaccessible information were the main challenges faced by farmers and extension agents in implementing innovations. Nevertheless, cooperation from all parties can lead to an excellent distribution of knowledge and skills among farmers.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73658312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The food and agriculture industries are also experiencing the effects. The COVID-19 epidemic disrupted the regular delivery system of agricultural extension services and the delivery of agricultural produce to markets. The study aimed to determine farmers' readiness to address post-MCO challenges in technology, implementation, decision-making, and leadership. Following the COVID-19 rules of reducing close contact to minimize virus transmission, a structured questionnaire was delivered to farmers online (Google form) and face-to-face with the support of extension agents. The results show that the relationship between independent and dependent variables was positive. Also, according to the findings, decision-making is the most crucial element influencing farmers' readiness to tackle post-movement control order issues.

Astrovirus is frequently associated with enteric diseases in poultry, being isolated from cases of runting-stunting syndrome (RSS) of broiler chickens, poult enteritis complex (PEC), and poult enteritis mortality syndrome (PEMS) of turkeys. Avian astrovirus can be detected in chickens from both healthy and poorly performing flocks. In Malaysia, information and reports regarding chicken astrovirus (CAstV) in poultry are limited. The objective of this study is to perform a phylogenetic study on the avian astrovirus isolated from a suspected case in 2019 and to determine the subgroups of avian astrovirus strains that existed in Malaysia. Reverse Transcription Polymerase chain reaction (RT-PCR) was performed based on the partial ORF1b gene and the nucleotide sequence was analyzed. Phylogenetic analysis showed that this isolate was clustered together with CAstV strains from several strain from USA, Malaysia and others. Furthermore, the isolate from broiler chicken showed 97.2% to 99.4% of its nucleotide identity with isolates from the American strains, compared to the previously CAstv Malaysia strain, which shared 94.8% to 95%.Therefore, the current study provides important information on the epidemiology of CAstV and highlights the importance of control strategies against CAstV-infected poultry in Malaysia.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89539174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study was conducted to examine the effects of chitosan at different concentrations (0.5%, 1.0% and 2.0%) on the shelf life of green chilies stored at ambient temperature (27°C) for 21 days. The effectiveness of the chitosan treatments in extending green chilies’ shelf-life was evaluated by determining their physical and chemical qualities. Coated green chilies are able to preserve for a longer period of time compared to uncoated green chilies. Regardless of any chitosan concentration, the total soluble solid content (TSS) of coated green chilies had increased starting from day 3 to day 21 day as compared to the control. At the highest concentration of 2.0%, chitosan treatment was able to reduce the pH by 28% on day 6 of the storage period, meanwhile, the pH was maintained across the concentration at the end of the storage period (day 21). It was found that the green chilies faced 10 to 22% weight loss across the concentration as compared to the control at the end of the storage period, where the highest weight loss was prominent at 2.0% chitosan. However, in terms of firmness, the chitosan treatments do not give any significant effect on all the treated green chilies. These results suggest that the application of edible chitosan coating contributes to lower pH and weight loss which is responsible for the longer shelf life of the green chilies.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91499282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This scoping review is guided by a primary research question - what is the inter-relationship between COVID-19 and climate change.

The combination of six different stabilizers such as Guar gum (GG), Carboxyl methyl cellulose (CMC), Arabic gum (AG), Xanthan gum (XG), Propylene glycol alginate (PGA), and Pectin were applied to PGJD formulation. Meanwhile, about three emulsifiers which are Arabic gum (AG), Polysorbate 80 (P80), and Propylene glycol alginate (PGA) were used to emulsify vitamin E in PGJD. The ratio for both stabilizers and emulsifiers varied accordingly. The most stable and suitable combination of stabilizers and emulsifiers was later added to PGJD. The combination of XG and CMC at the concentration of 70:30 with 0.2% (w/v) was the best stabilizer. Meanwhile, P80 was found to be the best emulsifier at a concentration of 0.8% (w/v) and PGJD fortified with 225 mg of vitamin E was chosen as the most acceptable PGJ among panelists.
