The mechanism underlying primordial follicle activation is poorly understood. In this study, in-vitro culture and subsequent xenotransplantation were conducted to determine whether testosterone promotes the of porcine follicles.Prepubertal ovarian cortical strips containing follicles cultured in presence for 7 days, subsequently transplanted immunodeficient mice 2 months. After transplantation, development was examined histologically. androgen receptors oocytes assessed by use western blot...
A recent outbreak of FAW (Spodoptera frugiperda) caused a substantial yield loss in corn was recorded Sri Lanka especially from Uva, Eastern and North Central provinces. This first reported August 2018 over the last six months, livelihood majority small-scale farming families greatly affected. National mobilization resources, agriculture related institutions together with university academia actively participated government campaign combating pest improving affected people all country. The...
Abstract Follicular progression during peripuberty is affected by diet. Vascular endothelial growth factor A (VEGFA) induces follicle in many species; however, there are limited studies to determine if diet may alter the effects of angiogenic VEGFA165-stimulated or antiangiogenic VEGFA165b arrest. We hypothesized that affects magnitude and VEGFA isoform actions on follicular development through diverse signal transduction pathways. To test this hypothesis, beef heifers our first trial...
Emergence of babesiosis in both public health and food security concern global perspectives cannot be ignored. The dairy farming plays an important role industry that, fulfilling the protein requirement through producing milk meat. operations may get hampered due to non-infectious infectious diseases. Infectious diseases also cause huge production losses all time time. Babesiosis becomes a major animal specialists recent years locally internationally severity out breaks, carrier animals...
Estrogen activity, a central component of reproductive growth, is regulated by the receptor proteins, estrogen alpha (ERα), and ER beta (ERβ) in chickens as many other species. ERα expresses predominantly gonads. Although expression embryonic gonads has been studied detail, post-hatching male not adequately. Therefore, current research was conducted to determine changes left with age.Shaver Brown were raised cared for according management guide sacrificed at intervals 1, 4, 8 weeks age. The...
In mammals, the mechanisms regulating initiation of follicle development remain poorly understood. We previously reported that testosterone induced activation porcine primordial follicles after 7 days culture. Herein, effect KIT ligand (KL) on viability, and was examined. Ovarian strips containing were cultured for in a medium supplemented with KL (10, 100, 250 or 500 ng/ml). The percentage degenerated significantly decreased (39 ± 2%) 100 ng/ml KL-treated group compared to control (56 1%),...
Black soldier fly larvae (BSFL; Hermetia illucens L.) is a proven high-cost protein source replacer and could be grown in range of bio-degradable waste materials where hardly incorporated into broiler diets locally. The present study was aimed to assess the nutritional composition BSFL, apparent metabolizable energy (AME) value BSFL meal provided chickens. full-fat produced from kitchen as substrate were examined for their proximate composition, minerals fatty acid profile. Eighty, 21-d old...

The uncontrolled waste generation is a prevailing environmental concern where management critical issue in Sri Lanka. Even though different methods are practicing, insect-basedbio-degradation forthcoming. Black soldier fly larvae (BSFL,Hermetia illucens) based emerging technology has recognized for the conversion of biodegradable into potentially more sustainable and marketable nutrient rich compost animal feed with crude proteins. study aims evaluate potentials to introduce BSFL...
Mammalian ovaries contain a large stock of oocytes enclosed in primordial follicles. A limited number follicles start to develop, while the remaining numbers them are quiescent. The mechanisms controlling initiation oocyte growth and follicle development remain be elucidated. Recent studies have shown that testosterone regulates early stages folliculogenesis recruitment vivo vitro. objective this study was examine effect on cultured porcine ovarian tissues subsequent xenotransplantation....
Purpose: Cattle recovered from clinical babesiosis become carriers for a certain period posing threat of transmitting the disease to entire herd. Diagnosis carrier cattle is important preventing outbreaks babesiosis. The objective present study therefore, was establish sensitive rapid detection method bovine in suspected using nested PCR (nPCR).Research Method: Accordingly, 30 blood samples and ticks were collected representing two bio-climatic zones Sri Lanka. Blood analysed by both...
Tropical Agricultural Research and Extension is a peer-reviewed international scientific journal covering wide range of subject areas in tropical subtropical agriculture published quarterly by the Faculty Agriculture, University Ruhuna, Sri Lanka. The also available on Ruhuna website https://www.agri.ruh.ac.lk/tare/index.htm .
Purpose: The quality of DNA and reliability molecular markers are crucial for the success Polymerase Chain Reaction (PCR) based genetic sex determination. This study was aimed at investigating optimum conditions isolation from chicken blood reproducibility dominant co-dominant to be validated as a tool successful sexing in avian research.Research Method: Efficacy six different extraction procedures including manual solution commercial purification kit were evaluated with combinations initial...
Viable waste management using insects are in trend, nevertheless no significant practices available locally. The black soldier fly larvae (BSFL; Hermetia illucens) have proven successfully the decomposition of organic matter savagely, enriched with favorable amino acid source for animal feed. study intended to compare life cyclemodalities ofBSFLwith two different substrates, swill (T1) and poultry starter feed (T2), by assessing days taken completion cycle, egg larval characteristics crude...
