Climate change is a contemporary global challenge that requires comprehensive solutions to mitigate its adverse effects. All human activities contribute climate change, mainly through atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). While most these are primarily due fossil fuel use, agriculture livestock production also significant share approximately 12% emissions. Most processes implemented within an animal husbandry...
Over the second half of 20(th) century much research on lipogenesis has been conducted, especially focused increasing production efficiency and improving quality animal derived products. However, many diferences are observed in physiology between species. Recently, studies have also elucidated involvement numerous genes this procedure, highlighting not only at but molecular level. The main scope review is to point out major differences ruminant non species, that key regulatory involved...
The contribution of domestic cattle in human societies is enormous, making cattle, along with other essential benefits, the economically most important animal world today. To expand existing knowledge on domestication and mitogenome diversity, we performed a comprehensive complete analysis species (802 sequences, 114 breeds). A large sample was collected South-east Europe, an agricultural gateway to Europe during Neolithization region rich biodiversity. We found 1725 polymorphic sites (810...
In recent years, welfare, which includes pleasurable and unpleasant emotions, is of utmost importance in animals reared under intensive farming systems. Various indices have been reported to evaluate welfare. Among them, vocalizations form non-invasive animals' inner state. The aim the study was determine whether changes ewes' raising group composition may alter differences their vocal characteristics. Forty two dairy sheep breeds (Chios Karagouniki) were used. experiment lasted for six...
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...
A 2-trial experiment was conducted to evaluate the effects of caponization on growth performance, carcass composition, and meat quality medium growing broilers. Male chicks were caponized at 3 wk age reared until either 18 (trial 1) or 24 2) age. In trial 1, experimental groups included intact males, sham-operated chickens, capons, whereas 2 comprised only males capons. The concentration testosterone drastically reduced by but remained detectable 1). both trials, BW lower for capons during 4...
Fifty-six Holstein dairy cows from a commercial herd in the Northern part of Greece were used to determine effect vitamin E supplementation on immune parameters, milk composition and quality. Cows assigned one two experimental groups: control (no supplementation) supplementation. Supplementation started 4 weeks prior continued up 12 after parturition. included daily oral administration at 3000 i.u./cow prepartum was reduced 1000 post partum . Blood samples collected weekly for 8 starting...
The present experiment was conducted in order to evaluate the effects of caponization on growth, carcass composition and meat quality males a layer line reared until 34th week age. Two hundred fifty were purchased randomly divided two equal groups: intact capons. Caponization at 45 days Three slaughters performed ages 26, 30 34 weeks did not affect feed intake final live weight. Capons had heavier breast lighter leg than males. Lipid accumulation enhanced by fat stored mainly pad skin...
1. Capons and intact male broilers were used to investigate the effects of caponisation on intramuscular fat abdominal adipose tissue lipid content fatty acid profile. 2. had significantly higher total (P < 0·05). 3. Neutral lipids major fractions in but their proportions differed among groups tissues 4.

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...

Different approaches (i.e., agronomic models, statistical regression equations linking thermal stress to output) were combined estimate from changes average values climatic parameters, subsequently economic this long-term change. Recorded damages events together with thresholds per event these...
The objective of this study was to evaluate the effect oregano essential oil dietary supplementation on feeding and drinking behaviour as well activity broilers. One hundred twenty female Redbro chicks were randomly assigned three treatments: Controls, R1 R2 with 0, 100 250 mg added per Kg feed, respectively. Their recorded from 35-63 days age. probabilities a bird feeding, moving significantly decreased by higher inclusion level having greater effect. age time day both had small but...
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...
An experiment was conducted in order to evaluate the effects of gestational undernutrition rabbit does on growth, carcass composition and meat quality offsprings. Thirty primiparous non lactating were artificially inseminated randomly divided three treatment groups: Control (C; fed 100% maintenance requirements throughout gestation, n = 10), early undernourished (EU; 50% during days 7–19 10) late (LU; 20-27 10). During 4th week gestation period, LU significantly lost weight compared C EU...
Although pig meat accounts for nearly half of total production in Europe, less attention has been focused on the greenhouse gas (GHG) emissions farming. The aim this study was to assess and compare impact livestock GHG during period 2015–2020 major European countries, including Greece, using different computational approaches (Tier 1, Tier 2, Gleam-i software v. 2.0 developed by FAO, Rome, Italy). A semi-extensive farm also used as a small-scale scenario. ranking countries related not...

The poultry sector is considered to be one of the most industrialized sectors livestock production. Although contributes 14.5% total anthropogenic greenhouse gas (GHG) emissions, less attention has been paid in respective emissions compared other farmed animals such as ruminants. aim study was estimate carbon footprint (layers, broilers, and backyards) Greek territory during last 60 years a means exploring further mitigation strategies. Tier 2 methodology used GHG emissions. Different...
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.
