Impact of climate change and man-made irrigation systems on the transmission risk, long-term trend and seasonality of human and animal fascioliasis i…

2014

Large areas of the province of Punjab, Pakistan are endemic for fascioliasis, resulting in high economic losses due to livestock infection but also affecting humans directly. The prevalence in livestock varies pronouncedly in space and time (1-70%). Climatic factors influencing fascioliasis presence and potential spread were analysed based on data from five mete- orological stations during 1990-2010. Variables such as wet days (Mt), water-budget-based system (Wb-bs) indices and the normalized difference vegetation index (NDVI), were obtained and correlated with geographical distribution, seasonality patterns and the two-decade evolution of fascioliasis in livestock throughout the province. …

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…

CAP POLICY DIMENSIONS: A CATALYST FOR COLLABORATION AND SUSTAINABLE CHANGES

2015

A great challenge to EU livestock production markets is the growing production price and the farmers' income variability. The public request for traceability and accountability determined the EU agri-food policy to implement new sustainable reform. In this paper the author identified a set of inputs and impacts of CAP sustainable reform on livestock system.International major competitors are assessed to benchmark the competitiviness of EU agri-food industry.

Cellulolytic activity in Aspergillus spp. contaminating livestock feeds and raw materials

2020

The contamination by Aspergillus spp. have become a global concern in food and feedstuffs and can lead to a reduction in yield and quality of agricultural products with significant economic losses. Most species of Aspergillus produce cellulose-degrading enzymes and some of them also have mycotoxigenic activity. This study aimed i) to evaluate the Aspergillus contamination in feeds (16) and row materials (32) collected in Sicily; ii) to isolate and identify fungi belonging to the genus Aspergillus and iii) to analyze their ability to produce cellulolytic enzymes. Aspergillus spp. contamination was evaluated on PDA using serial ten-fold dilution and spread plate technique (Mirabile et al., 20…

The management of crop-livestock systems at a territory level: the example of grain legume crops and of monogastric livestock in Burgundy, France

2012

Although cereals and oil seed crops are very developed in Burgundy, the area of grain legumes cultivation is small. Concerning monogastric livestock, the region is characterised by a medium size poultry production focussed on markets under quality and origin signs (SIQO) and a relatively small pig production. Although a tendency of co-location of these productions can be observed (at territory and farm scales) and some animals consume locally-produced proteins, there is no strong functional link between these crops and animal activities. This situation is confirmed by the fact that a significant proportion of produced grain legumes are exported by Burgundy, while large quantities of soybean…

Penalized classification for optimal statistical selection of markers from high-throughput genotyping: application in sheep breeds

2018

The identification of individuals’ breed of origin has several practical applications in livestock and is useful in different biological contexts such as conservation genetics, breeding and authentication of animal products. In this paper, penalized multinomial regression was applied to identify the minimum number of single nucleotide polymorphisms (SNPs) from high-throughput genotyping data for individual assignment to dairy sheep breeds reared in Sicily. The combined use of penalized multinomial regression and stability selection reduced the number of SNPs required to 48. A final validation step on an independent population was carried out obtaining 100% correctly classified individuals. …

Effetto del sistema di allevamento e della tecnologia di caseificazione sulla qualità del caciocavallo palermitano.

2011

Effects of livestock system and cheese making technique on the quality of Caciocavallo Palermitano cheese - Caciocavallo Palermitano is a typical stretched curd cheese produced in the Central and Western Sicily. It is traditionally obtained from whole milk of indigenous cows breeds and by the original cheese making technology in which wooden tools, source of inoculum of autochthonous lactic bacteria, are used. Recently, Caciocavallo Palermitano cheese is also obtained in dairy intensive farms of specialized breeds where milk is processed mainly using stainless steel equipment and commercial selected lactic ferments. The aim of this investigation was to verify the influence of cheese making …

Case Study of Potential Production of Renewable Energy Sources (RES) from Livestock Wastes in Mediterranean Islands

2017

The aim of this work is to evaluate the potential production of Renewable Energy Sources (RES) from livestock wastes that are commonly found on Mediterranean islands, by using the island of Malta as a case study. Organic wastes in the form of livestock manure and slurry, as well as other by-products originating from the food transformation industry in the making of alcoholic beverages and the processing of olives, tomatoes and other streams, if mixed in such a way to achieve a correct C/N ratio, can be subjected to anaerobic co-digestion for the production of biogas and digestate. Biogas can be further transformed into biomethane, a fuel that can be used to power surface transportation and …
