In the present study, the growth performance of the critically endangered Hypselobarbus pulchellus in biofloc-based seed rearing with different Carbon to Nitrogen ratio was studied. Methods: Healthy early fry (0.01 g) was randomly stocked into 15 circular FRP tanks (1000 L) at a density of 100 individuals/m3 and reared for 90 days. The carbon to nitrogen ratios of 5:1(CN5), 10:1(CN10), 15:1(CN15) and 20:1(CN20) were maintained using jaggery without considering carbon content derived from the feed and the control group received no additional source of carbon. Result: The results indicated that H. pulchellus had better growth performance in biofloc systems having higher C/N ratios. The highest weight gain (0.48±0.01 g) and weight gain percentage (3931.15±120.68%) and specific growth rate (4.11±0.03% per day) were found in the CN10 group (P less than 0.05), followed by CN15 and CN20, while the control group values were lowest. In terms of survival, all treatments had high survival rates ranging from 92% to 94.67%, with no significant variations (P greater than 0.05). The CN10, CN15 and CN20 treatments had significantly higher amylase, protease and lipase activities than control (P less than 0.05). Moreover, the immunological and antioxidant activity increased with CN ratios. The CN10, CN15 and CN20 groups had significantly lower total ammonia nitrogen, nitrite and nitrate levels than control group (P less than 0.05).

The larval stage of E. granulosus causes cystic hydatidosis in humans and livestock. Although most hydatid cysts are found in the liver and lungs, the disease can occur anywhere in the body. Therefore, Hydatidosis remains a problem and causes significant economic losses in animals. Methods: A study was performed to evaluate the activity of the leaves Nerium oleander extract on the viability of protoscolices. We used three graduated concentrations of extract (10, 30 and 50 mg/ml). 2 ml of the protoscolices suspension (containing at least 2700 protoscolices) was placed in test tubes using a Pasteur pipette. Then, 2 ml of various concentrations of the Nerium oleander extract were added to each test tube and mixed gently, incubated at 37°C for 5, 10, 20 and 30 min. One control group was kept that contain normal saline. The viability of protoscolices was evaluated by eosin method where, protoscolices suspension was mixed with 0.1% eosin for 5 minutes. The dead protoscolices absorb eosin and becomes red, whereas the live protoscolices remains colorless. Before drawing the conclusion, each experiment was performed thrice. Result: The analysis of phytochemicals by FT-IR for alcoholic extracts of Nerium oleander extracts revealed the presence of 12 effective chemical ingredients. Nerium oleander extract showed the strongest scolicidal effect (85.6, 92.3%) after 20 and 30 min at a concentration of 50 mg/ml, respectively moderately (69.3%) after 30 min at 30 mg/ml and lowest (41.9%) after 30 min at 10 mg/ml. Microscopic examinations of dead protoscolices showed distortion of their morphology and degenerative effects. These effects were characterized by loss of hooks, or presence of free hooks and dissolution and rupture of the protoscolices wall. It can be concluded from this study that ethanol extract of Nerium oleander is effective against Protoscolies in vitro.\u0000","PeriodicalId":13410,"journal":{"name":"Indian Journal of Animal Research","volume":"99 7","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138590679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These parasites, responsible for Cryptosporidiosis and Giardiasis, are significant health concerns and have garnered attention from both the public and veterinary fields. Pets, such as dogs and cats, are susceptible to these infections and play a crucial role in transmitting these protozoans to humans. This study was conducted to determine the prevalence, species, genotypes and zoonotic significance of Cryptosporidium and Giardia in asymptomatic adult stray cats and dogs. Methods: Fecal samples from 75 adult stray animal, 42 dogs and 33 cats, were collected in Diyarbakýr city, southeastern Anatolia, Turkey. Direct immunofluorescence test was used to confirm the presence of G. duoenalis cysts and cryptosporidium spp. oocysts in collected fecal samples. Microscopic analysis was used to count the number of cysts/oocysts per gram as specified by the manufacturer. Molecular confirmation was done with Polymerase chain reaction (PCR) using Giardia SSU-rDNA and Cryptosporidium spp. SSU rRNA gene. The secondary PCR products of all positive samples were sequenced in one directions on an automated sequencer. Nucleotide sequence analysis was performed by BLAST alignment using the National Center for Biotechnology Information database. Result: The prevalence of Cryptosporidium was 7.14% in 42 cats and 9.09% in 33 dogs. The prevalence of G. duodenalis was 23.80% in cats and 54.54% in dogs.

The physicochemical properties and varied effects against insect pests make plant extracts a potential alternative in the development of pesticides. Methods: In this study, we assayed the oleander leaf extract toxicity effects against T. castaneum adults in the laboratory. We used four concentrations of Oleander methanol leaf extract. Result: Exposure of T. castaneum adult to the oleander leaf extracts produced 100% mortality in the insecticidal bioassay, especially at 40% concentration. The mortality % ranged from 13.3-100% after 48hrs. The mortality percentage of the red flour beetle adults decreased by increasing exposure periods. The mortality % was highly negatively correlated with exposure times (R= -0.97, P =.0001; R= -0.80 and P=.0001) at 40 and 20% concentrations, respectively. The overall results of the current study suggest that the leaf extract of Nerium oleander may possess potential insecticidal properties, which could potentially be employed in pest management. The infrared analysis of the oleander leaf extract showed many bioactive components associated with plant secondary metabolites; some of these identified phytochemical compounds have biological activity. Further, the phenol and flavonoid total were estimated. We conclude that the oleander leaf extract has the potential to be useful in managing stored grain insect pests, particularly T. castaneum, but that it must be handled and applied with extreme caution.","PeriodicalId":13410,"journal":{"name":"Indian Journal of Animal Research","volume":"19 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139218665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
