        Effect of feeding of blend of essential oils on methane production, growth, and nutrient utilization in growing buffaloes

        Yatoo, M.A.,Chaudhary, L.C.,Agarwal, N.,Chaturvedi, V.B.,Kamra, D.N. Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.5

        Objective: An experiment was conducted to study the effect of a blend of essential oils (BEO) on enteric methane emission and growth performance of buffaloes (Bubalus bubalis). Methods: Twenty one growing male buffaloes (average body weight of $279{\pm}9.3kg$) were divided in to three groups. The animals of all the three groups were fed on a ration consisting of wheat straw and concentrate mixture targeting 500 g daily live weight gain. The three dietary groups were; Group 1, control without additive; Group 2 and 3, supplemented with BEO at 0.15 and 0.30 mL/kg of dry matter intake (DMI), respectively. Results: During six months feeding trial, the intake and digestibility of dry matter and nutrients (organic matter, crude protein, ether extract, neutral detergent fibre, and acid detergent fibre) were similar in all the groups. The average body weight gain was tended to improve (p = 0.084) in Group 2 and Group 3 as compared to control animals. Feeding of BEO did not affect feed conversion efficiency of the animals. The calves of all the three groups were in positive nitrogen balance with no difference in nitrogen metabolism. During respiration chamber studies the methane production (L/kg DMI and L/kg digestible dry matter intake was significantly (p<0.001) lower in Group 2 and Group 3 as compared to control animals. Conclusion: The results indicated that the BEO tested in the present study have shown potential to reduce enteric methane production without compromising the nutrient utilization and animal performance and could be further explored for its use as feed additive to mitigate enteric methane production in livestock.

        A new species of the genus Spilomyia Meigen, 1803 (Diptera: Syrphidae) from South Asia

        Maqbool Amir,Wachkoo Aijaz Ahmad,Yatoo Suhaib Firdous,Skevington Jeffrey H.,van Steenis Jeroen 한국응용곤충학회 2024 Journal of Asia-Pacific Entomology Vol.27 No.2

        The genus Spilomyia (Insecta, Diptera, Syrphidae) consists of 39 species worldwide. One species previously listed from South Asia as Spilomyia manicata (Rondani, 1865), is herein described as a new species, Spilomyia recta van Steenis, Maqbool & Wachkoo sp. n. The new taxon represents the only valid species of Spilomyia from India and Pakistan and the third species known from Afghanistan and thus occurring in both the Palaearctic and Oriental region. Morphologically it is similar to the European species Spilomyia manicata, however based on the features of the male genitalia and molecular COI data the species is more closely related with S. diophthalma. Both morphological and molecular characteristics clearly separate these three species. Descriptions, diagnoses, high quality images, and phylogenetic relationships are presented. http://zoobank.org/urn:lsid:zoobank.org:pub :78A9D482-468F-41EB-B602-D854AE159327.

        Endoscopic Yield, Appropriateness, and Complications of Pediatric Upper Gastrointestinal Endoscopy in an Adult Suite: A Retrospective Study of 822 Children

        Manzoor Ahmad Wani,Showkat Ali Zargar,Ghulam Nabi Yatoo,Inaamul Haq,Altaf Shah,Jaswinder Singh Sodhi,Ghulam Mohammad Gulzar,Mushtaq Khan 대한소화기내시경학회 2020 Clinical Endoscopy Vol.53 No.4

        Background/Aims: This study aimed to study the endoscopic yield, appropriateness, and complications of pediatric endoscopyperformed by adult gastroenterologists in an adult endoscopic suite. Methods: This a retrospective study in which records of all the patients less than 18 years of age who underwent endoscopy in the last5 years were studied. The indications of endoscopy in children were categorized as appropriate or inappropriate per the latest guidelinesby American Society for Gastrointestinal Endoscopy and North American Society for Pediatric Gastroenterology, Hepatology andNutrition. Positive endoscopic yield was defined as the presence of any abnormality on endoscopy. Results: Among the total of 822 children (age <18 years), the most common indications were variceal surveillance/eradication in 157(19.1%), followed by dyspepsia in 143 (17.4%), upper gastrointestinal (UGI) bleeding in 136 (16.5%), recurrent abdominal pain in 94(11.4%), unexplained anemia in 74 (9%), recurrent vomiting in 50 (6.08%), chronic refractory gastroesophageal reflux disease in 34 (4.1%)and others; 780 out of 822 endoscopic procedures (94.9%) done in children were appropriate as per the guidelines. The endoscopicyield was 45.8%, highest in patients with UGI bleeding (71.3%), followed by variceal surveillance (54.8%), recurrent vomiting (38%),dyspepsia (37.8%), and recurrent abdominal pain (36%). Minor adverse events occurred in 7.3% of children. Conclusions: Pediatric endoscopy performed by an experienced adult gastroenterologist may be acceptable if done in cooperation witha pediatrician.
