Summary This study investigated the effects of dietary inclusion rumen‐protected methionine alone or in combination with choline and betaine on: (i) milk yield, chemical composition fatty acids ( FA ) profile (ii) blood plasma glutathione transferase GST activity periparturient ewes. Furthermore, oxidative stress indicators for measuring total antioxidant free radical scavenging [ferric reducing ability FRAP 2,2′‐azino‐bis (3‐ethylbenzothiazoline‐6‐sulphonic acid) ABTS assays] were also...
This study aims to examine the genetic structure and diversity levels of seven indigenous Greek horse breeds: Andravida, Pindos, Thessaly, Skyros, Penia, Messara Rodos, using 15 microsatellites. Phenotypic traits were combined with factorial correspondence analyses create two datasets: one “Baseline” containing typical samples, “Unknown” non-typical or disputed origin samples. In horses, 142 alleles found. The mean observed effective number alleles, polymorphism information content allelic...
After the domestication of goats around 10,000 years before present (BP), humans transported far beyond range their wild ancestor, bezoar goat. This brought domestic into contact with many goat species such as ibex and markhor, enabling introgression between goats. To investigate this, while shedding light on taxonomic status goats, we analysed genome-wide SNP data 613 specimens from 14 units, including Capra hircus, C. pyrenaica, (from Switzerland, Austria, Germany Slovenia), aegagrus...
Abstract Background The indigenous cattle populations from Greece and Cyprus have decreased to small numbers are currently at risk of extinction due socio-economic reasons, geographic isolation crossbreeding with commercial breeds. This study represents the first comprehensive genome-wide analysis 10 continental Greek islands, one Cyprus, compares them 104 international breeds using more than 46,000 single nucleotide polymorphisms (SNPs). Results We estimated several parameters genetic...
The purpose of this study is to investigate a novel exploitation approach for mass livestock byproduct, namely sheep wool fibres. In order fulfil aim, fibre toughened epoxy composites with an amount 2.4, 4.1 and 5.7 phr were prepared via the hot press method. Initially, mechanical assessment was executed, in evaluate their integrity. flexural shear strength tests showed that fibre-epoxy maintain properties up no degradation detected. Subsequently, thermal tested. Thermogravimetric analysis...
This study examined the effects of milking frequency, breed, and stage lactation on milk fat globules (MFG) size fatty acids (FA) composition sheep milk. Milk from Karagouniko (n = 13) Chios ewes was sampled postpartum 93rd, 101st, 108th, 121st, 156th, 188th days lactation. On 108th day, were divided randomly into two groups: Once daily at 06:00 a.m. or twice 16:00 p.m. Morphometric characteristics MFG FA determined for each sample. versus had no effect dimensions, which tended to vary...
Abstract Introduction The aim of this study was to determine changes reactive oxygen species (ROS), serum antioxidant capacity (SAC), oxidative stress index (OSi), and α -tocopherol ( -T) during the periparturient period in healthy mastitic cows further investigate whether these parameters can be used as a tool for identifying at higher risk developing mastitis. Material Methods Blood samples from 110 dairy two commercial farms were obtained dry-off, calving, 30 days post-partum. Healthy...
Abstract The animal selection with favourable phenotypes of the past has been, currently, replaced by genotype on quantitative traits, assisted expanding molecular techniques in context livestock improvement. In this study, c.112T>C polymorphism exon II β-lactoglobulin (β-LG) gene was investigated Karagouniko and Chios sheep breeds using polymerase chain reaction - restriction fragment length (PCR-RFLP), possible associations milk traits were examined. total, 125 blood DNA samples...
The aim of the study was to determine changes in reactive oxygen species (ROS), serum antioxidant capacity (SAC) and oxidative stress index (OSi; ROS/SAC) from dry off 30 days postpartum dairy cows. Furthermore, relationship between indices status (ROS, SAC, OSi) related metabolic disorders (blood free fatty acids, FFA β-hydroxybutyrate, BHB) α-tocopherol (α-Τ) determined. Blood samples were collected 131 cows belonging four commercial farms, located Italy Greece. at dry-off, calving...
Abstract Most ungulate mammals are social species that live in large groups where agonistic encounters with con‐specifics common. Such interactions may be a source of distress and can pose threat to group's cohesion. Group stability achieved by third‐party interventions, defined as the behavior individuals (interveners) interrupting between two through direct physical contact, interposition, or threats. This costly for intervener but lead benefits like reciprocity, group cohesion, enhance...
In Greece, all cattle carcasses produced from a variety of breed types are classified according to the SEUROP system. The objective this study was evaluate Greek carcass characteristics such as weight and age slaughter based on classification system (muscle conformation fat deposit classes) describe effect main factors breed, gender, year slaughter, farm’s geographical region month these parameters. It is first that evaluates local breeds, revealing wide diversity breeding conditions....
In this study, we analyzed microsatellite variation in DNA obtained from hair samples collected 46 local Greek horse populations originating the islands of Skyros (Skyros Small Horse; n=9), Rhodes (Rodos n=6), Lesvos (with traditional miniature Midili Horse (n=2) and larger Gaiter (n=22)) Crete (Messara) (n=7). We used 15 autosomal markers (VHL20, HTG4, AHT4, HMS7, HTG6, AHT5, HMS6, ASB2, HTG10, HTG7, HMS3, HMS2, ASB17, ASB23 LEX33) for genetic characterization above exploration their...
Abstract Ear length in sheep ( Ovis aries ) shows a wide range of natural variation, from the absence an outer ear structure anotia ), to small ears microtia regular length. Up until now, underlying genetics this phenotype has been studied four breeds China, Jordan and Italy. These studies revealed broad genes significantly associated with length, potentially indicating genetic heterogeneity across or geographic regions. In current study, we performed genome‐wide SNP genotyping...
The Ovar-DRB1 gene locus is one of the most polymorphic genes Major Histocompatibility Complex (Ovar-MHC) and holds a functional role to antigen presentation. aim this study was: a) describe variability in two dairy Greek sheep breeds b) investigate associations between with resistance gastrointestinal parasitosis. Blood faecal samples were collected from 231 201 animals Arta Kalarrytiko breeds, respectively. identification alleles was performed using sequence–base method. Faecal egg...
