        Gryllus testaceus walker (crickets) farming management, chemical composition, nutritive profile, and their effect on animal digestibility

        Shah Assar Ali,Wanapat Metha 한국곤충학회 2021 Entomological Research Vol.51 No.12

        Commonly, the life span of the cricket is very short, reaching from 60 to 70 days and the average egg production lies within the range of 200–1,500 eggs/female. The female can mate with many males and can produce more fertile eggs. The body composition of an adult cricket on analysis showed that it contains dry matter 33.30%, crude protein 63.30%, crude fat 5.20%, ash 5.60%, calcium 10.10%, phosphorous 7.90%, zinc 215.0 mg/kg, and copper 15.00 mg/kg on dry matter basis, respectively. The dry matter digestibility diet was highest for whole cricket (WC, with legs) and the digestibility of ash, crude fiber, and crude fat was higher than form body cricket (BC, removal of legs). The WC and BC diets had lower feed conversion rates than control diets, and higher nitrogen retention (digestion). It was concluded that crickets are potential feed ingredients for ruminants and non-ruminants, especially as protein supplements methane emissions are low in vitro and high ash digestibility indicates the ability to reduce mineral deficiencies.

        Nutritional composition of various insects and potential uses as alternative protein sources in animal diets

        Shah Assar Ali,Totakul Pajaree,Matra Maharach,Cherdthong Anusorn,Harnboonsong Yupa,Wanapat Metha 아세아·태평양축산학회 2022 Animal Bioscience Vol.35 No.2

        The aim of the present investigation is to determine the nutritional composition of various insects and their potential uses as alternative protein sources in animal diets. The feeding industry requires production systems that use accessible resources, such as feed resources, and concentrates on the potential impacts on production yield and nutritional quality. Invertebrate insects, such as black soldier flies, grasshoppers, mealworms, housefly larvae, and crickets, have been used as human food and as feed for nonruminants and aqua culture while for ruminants their use has been limited. Insects can be massproduced, participating in a circular economy that minimizes or eliminates food- and feed-waste through bioconversion. Although the model for formula-scale production of insects as feed for domestic animals has been explored for a number of years, significant production and transformation to being a conventional protein resource remains to be deeply investigated. This review will focus on the nutritional composition of various insects and their potential use as alternative protein sources, as well as their potential use to promote and support sustainable animal production. Furthermore, nutritional compositions, such as high protein, lauric acid omega 6, and omega 3, and bioactive compounds, such as chitin, are of great potential use for animal feeding.

        Pharmacological effect of Rubus ulmifolius Schott as antihyperglycemic and antihyperlipidemic on streptozotocin (STZ)-induced albino mice

        Khalil Akhtar,Syed Wadood Ali Shah,Assar Ali Shah,Muhammad Shoaib,Syed Kashif Haleem,Nighat Sultana 한국응용생명화학회 2017 Applied Biological Chemistry (Appl Biol Chem) Vol.60 No.4

        The aim of present study was to evaluate the antihyperglycemic and antihyperlipidemic effects of aerial parts of Rubus ulmifolius Schott on streptozotocin (STZ)- induced diabetic albino mice. A total of 48-, 60-day-old either sex (male and female) albino mice were treated with, normal control; 2% Tween-80 suspension (diabetic control); glibenclamide (500 lg/kg/orally); RU methanol extract (150 mg/kg/orally) (RUCrd1); RU methanol extract (300 mg/kg/orally) (RUCrd2); RU chloroform extract (150 mg/kg/orally) (RUC); RU ethyl acetate extract (150 mg/kg/orally) (RUE); and RU butanol extract (150 mg/kg/orally) (RUB) for a period of 15 days. Diabetes was induced in albino mice by single intraperitoneal injection of streptozotocin (50 mg/kg/b/w). After 15 days, group treated with glibenclamide, RUCrd1, RUCrd2, RUC, RUE and RUB exhibited a significant (P[0.05) decrease in blood glucose level as compared to diabetic control groups. The total cholesterol, triglycerides and low-density lipoproteins as well as serum creatinine level, serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase and alkaline phosphatase were also significantly (P[0.05) decreased in glibenclamide, RUCrd1, RUCrd2, RUC, RUE and RUB groups albino mice as compared to diabetic control. It was concluded that Rubus ulmifolius Schott extract has positive effect as hypoglycemic and antihyperlipidemic on diabetic albino mice.

        Microencapsulation of Mitragyna leaf extracts to be used as a bioactive compound source to enhance in vitro fermentation characteristics and microbial dynamics

        Maharach Matra,Srisan Phupaboon,Pajaree Totakul,Ronnachai Prommachart,Assar Ali Shah,Ali Mujtaba Shah,Metha Wanapat Asian Australasian Association of Animal Productio 2024 Animal Bioscience Vol.37 No.1

        Objective: Mitragyna speciosa Korth is traditionally used in Thailand. They have a high level of antioxidant capacities and bioactive compounds, the potential to modulate rumen fermentation and decrease methane production. The aim of the study was to investigate the different levels of microencapsulated-Mitragyna leaves extracts (MMLE) supplementation on nutrient degradability, rumen ecology, microbial dynamics, and methane production in an in vitro study. Methods: A completely randomized design was used to assign the experimental treatments, MMLE was supplemented at 0%, 4%, 6%, and 8% of the total dry matter (DM) substrate. Results: The addition of MMLE significantly increased in vitro dry matter degradability both at 12, 24, and 48 h, while ammonia-nitrogen (NH<sub>3</sub>-N) concentration was improved with MMLE supplementation. The MMLE had the greatest propionate and total volatile fatty acid production when added with 6% of total DM substrate, while decreased the methane production (12, 24, and 48 h). Furthermore, the microbial population of cellulolytic bacteria and Butyrivibrio fibrisolvens were increased, whilst Methanobacteriales was decreased with MMLE feeding. Conclusion: The results indicated that MMLE could be a potential alternative plant-based bioactive compound supplement to be used as ruminant feed additives.
