The Girgentana Goat Breed: A Zootechnical Overview on Genetics, Nutrition and Dairy Production Aspects

2017

In recent years, there has been a great interest in recovering and preserving local livestock breeds. An interesting situation is represented by the Girgentana goat, an ancient local breed reared in Sicily. Over recent years, this breed has become almost extinct, in part as a consequence of the marked decrease in fresh goat milk consumption. On the basis of these considerations, several studies on its genetic structure and management aspects have been conducted in order to protect the Girgentana goat from the risk of extinction and recover its genetic and economic value. In this context, information on genetics, nutrition and dairy production aspects may have a crucial role in the improveme…

Female Preference and Adverse Developmental Effects of Glyphosate-Based Herbicides on Ecologically Relevant Traits in Japanese Quails

2019

Controversial glyphosate-based herbicides (GBHs) are the most frequently used herbicides globally. An increasing number of studies have identified GBH residues in soil, water, and even human food that may expose nontarget organisms including wildlife, livestock, and humans to health risks. After a heated debate, the European Union allowed the use of GBHs to continue until 2022, after which their risks will be re-evaluated. Thus, decision makers urgently need scientific evidence on GBH residues and their possible effects on ecosystems. An important, yet neglected, aspect is to assess whether animals show preference or avoidance for GBH-contaminated food, as it can influence the likelihood of…

Economic performance of biogas plants using giant reed silage biomass feedstock

2015

Abstract With regard to energy crops for the production of raw materials to biomass for biogas plants, has developed a study to determine the optimal minimum size of a biogas plant powered by giant reed (Arundo donax L.) and utilizing livestock waste. In particular, all costs items relating to biomass supply, plant installation and transport costs were analyzed, by changing progressively two main variables: the electrical power capacity and the feedstock utilized (in the range from 100 to 999 kW) and the feedstock utilized, by substituting livestock waste with giant reed silage so as to determine the more economically advantageous option for the entrepreneur in proportion to power capacity …

Economic evaluation of biogas plant size utilizing giant reed

2015

Abstract Amongst energy crops for the production of biomass feedstock for biogas plants, giant reed (Arundo donax L) has been attracting attention in recent years in Italy. Undoubtedly, this is due to its potentially high yield in terms of biomass, low agronomic inputs, as well as for being eligible for European Union energy crop incentives. The aim of this study was to perform an analysis of plant costs considering three macro-categories (biomass, plant installation and transport). Also, we aimed to describe the economic performances of biogas plants, while progressively altering two key variables. Specifically, we considered electrical power capacity (in the 100–999 kW range) and several …

Genome-wide analysis in endangered populations: a case study in Barbaresca sheep

2017

Analysis of genomic data is becoming increasingly common in the livestock industry and the findings have been an invaluable resource for effective management of breeding programs in small and endangered populations. In this paper, with the goal of highlighting the potential of genomic analysis for small and endangered populations, genome-wide levels of linkage disequilibrium, measured as the squared correlation coefficient of allele frequencies at a pair of loci, effective population size, runs of homozygosity (ROH) and genetic diversity parameters, were estimated in Barbaresca sheep using Illumina OvineSNP50K array data. Moreover, the breed's genetic structure and its relationship with oth…

Human case of Fasciola gigantica-like infection, review of human fascioliasis reports in Nepal, and epidemiological analysis within the South Central…

2018

Abstract The diagnosis of a 22 year-old male patient from Kerabari, Morang District, Nepal led to the review of human fascioliasis cases and analysis of the epidemiological situation in that country not included in the WHO fascioliasis map. Symptom onset one month before egg detection and normal levels of ALT and AST did not agree with the 3–4-month migratory period of fascioliasis. A shorter acute phase may happen when the main biliary duct is reached by the migratory juveniles directly from the intestinal lumen. The causal agent was ascribed to F. gigantica-like worms after considering adult fluke morphology, altitude of the patient’s infection area, fasciolid characteristics in the neigh…
