Agouti and Extension loci control the relative amount of eumelanin pheomelanin production in melanocytes that, turn, affects pigmentation skin hair. The locus encodes melanocortin 1 receptor (MC1R) whose permanent activation, caused by functional mutations, results black coat colour, whereas other inactivating mutations cause red colour different mammals.The whole coding region MC1R gene was sequenced goats six breeds showing colours (Girgentana, white cream with usually small spots face;...
Genetic diversity has become an urgent matter not only in small local breeds but also more specialized ones. While the use of genomic data livestock breeding programs increased genetic gain, there is increasing evidence that this benefit may be counterbalanced by potential loss variability. Thus, study, we aimed to investigate Italian Holstein dairy cattle using pedigree and from cows born between 2002 2020. We estimated variation inbreeding, effective population size, generation interval...
The objectives of this study were 1) to estimate the heritability lamb survival and growth in Scottish Blackface breed; 2) examine relationship between live BW; 3) investigate possibility using a breeding program for breed. data used analyses contained information about BW at different ages on 4,459 animals. records collected from 1988 2003 flock. Live was recorded every 4 wk birth 24 wk. Survival defined either by perinatal or postnatal mortality (up weaning 12 wk), as cumulative 1, 4, 8,...
The quality of bovine colostrum, primarily determined by IgG concentration, is essential for the transfer passive immunity and development gastrointestinal tract in neonates. High concentration colostrum (BC) pivotal calf at first meal; however, while neonates often refuse to voluntarily drink recommended amount BC hours life, dam frequently fails produce a sufficient volume milking. This study seeks estimate h2 yield (CY) its genetic correlations with total Ig, IgG, protein, fat...
Twinning is undesirable in dairy cattle since it associated with higher risk of abortion, calving difficulty, and metabolic reproductive issues. Moreover, twin calves are lighter at birth generally have lower survival rate. As a result, twinning leads to significant economic losses for the farmer. In current study, genetic variance h2 rate (TR) were estimated as first step investigate feasibility reducing or least curb its increase Italian Holstein population through strategies. Calving...
Mastitis is an infectious disease affecting the mammary gland, leading to inflammatory reactions and heavy economic losses due milk production decrease. One possible way tackle antimicrobial resistance issue stemming from therapy select animals with a genetic this disease. Therefore, aim of study was analyze variability SNPs found in candidate genes related mastitis Holstein Friesian bulls. Target regions were amplified, sequenced by Next-Generation Sequencing technology on Illumina® MiSeq,...
Abstract The main objective of this study was to assess the microbiota diversity in milk samples collected from Holstein cows with different estimated breeding values for predicted feed efficiency, coagulation, resilience mastitis, and consequently, its effects on quality. One hundred twenty were two seasons (summer winter) commercial dairy farms Nord-east Italy. For each trait, 20 animals divided into groups high (10 cows) low selected profile using 16S rRNA metabarcoding sequencing. alpha...
The objective of this study was to evaluate the effect imputation single nucleotide polymorphisms (SNP) on estimation genomic inbreeding coefficients. Imputed genotypes 68,127 Italian Holstein dairy cows were analyzed. Cows initially genotyped with two high density (HD) SNP panels, namely Illumina Infinium BovineHD BeadChip (678 cows; 777,962 SNP) and Genomic Profiler HD-150K (641 139,914 SNP), four medium (MD): GeneSeek 3 (10,679 26,151 4 (33,394 30,113 MD (12,030 47,850 Labogena (10,705...
The objective of this study was to assess the effect using or not genotypes parents a cow for imputing SNPs on estimation genomic inbreeding coefficients cows. Imputation (i.e., genotyped plus imputed) from 68,127 Italian Holstein dairy cows registered in National Association Holstein, Brown, and Jersey Breeders were analyzed. Cows with high-density (HD) Illumina Infinium BovineHD BeadChip GeneSeek Genomic Profiler HD-150K, medium-density (MD) 3, 4, MD, Labogena MD. To differences among...
Abstract The aim of this study was to estimate genetic associations between alternative somatic cell count ( SCC ) traits and milk yield, composition udder type in Italian Jersey cows. Alternative were test‐day TD score SCS averaged over early lactation _150), standard deviation the entire _ SD ), a binary trait indicating absence or presence at least one >400,000 cells/ ml (Infection) ratio number total (Severity). Heritabilities traits, including lactation‐mean LM ranged from 0.038...
Among Italian dairy cattle, the Holstein is most reared breed for production of Parmigiano Reggiano protected designation origin cheese, which represents one renowned products in entire industry. In this work, we used a medium-density genome-wide data set consisting 79,464 imputed SNPs to study genetic structure breed, including population area cheese production, and assessing its distinctiveness from North American population. Multidimensional scaling ADMIXTURE approaches were explore among...
Abstract Gestation length (GL) can potentially affect health and performance of both the dam newborn calf, it is controlled by two genetic components, direct maternal. This means that calf (direct effect) cow (maternal genotypes contribute to determine GL its variability. The aims present study were estimate maternal variance components GL, develop a routine evaluation in Italian Holstein evaluate potential (un)favourable associations with traits for which selection undertaken this...
Milk protein genes are known to be highly polymorphic. Several studies have shown the influence of milk proteins genetic variants and casein haplotypes on nutritional technological properties. From 1990, analysis caseins polymorphism gained new attention due concern about possible negative effects CSN2*A1 human health. As a consequence, CSN2*A2 variant interest produced by with A2A2 β-casein cows is now available in different countries. Aim present paper was analyse how variants' haplotypes'...
The aim of this paper is to present an overview the actual Sicilian Girgentana population structure by analysis genealogical data. Statistics show that in 1983 consisted 30,000 goats; ten years later almost 98% entire disappeared. remaining consists 461 individuals (134 males and 327 females), with 368 living animals. effective size 380 individuals. inbreeding rate per generation was equal 0.13%. average estimated level within male 0.8% (0-15%); female 0.7% (0-31%). relationship between...
The aim of this study was to estimate the genetic parameters and predict experimental breeding values (EBVs) for saturated (SFA), unsaturated (UFA), monounsaturated (MUFA) polyunsaturated (PUFA) fatty acids, ratio productive traits in Italian Brown Swiss (BSW) Holstein Friesian (HOL) cattle. Test-day yields from 235,658 HOL 21,723 BSW cows were extracted Associations databases November 2009 October 2012 out 3310 herds. milk samples collected within routine recording scheme processed with...
Inbreeding depression has become an urgent issue in cosmopolitan breeds where the massive genetic progress achieved latest generations is counterbalanced by a dramatic loss of diversity causing increased health issues. Thus, aim this study was to estimate inbreeding on productive traits Holstein dairy cattle. More precisely, we aimed i) determine level 27,735 Italian cows using pedigree and genotype data, ii) quantify effect 305-d milk yield (MY; kg), fat (FY; protein (PY; kg) based...
