The primary aim of this study was to estimate heritabilities for different types claw and foot disorders the genetic relationship with milk yield selected conformation traits by applying logistic models in Holstein dairy cattle. included data from 5634 cows kept on large-scale farms Eastern Germany. Dichotomous response variables were presence or absence disorder 2003. Cows that present herds <6 wk 2003 excluded analysis. Incidences, disregarding repeated measurements, digital dermatitis...
Non-invasive methods of detecting heat stress magnitude for livestock is gaining momentum in the context global climate change. Therefore, objective this review to focus on synthesis information pertaining recent efforts develop detection systems based multiple behavioral and physiological responses. There are a number approaches quantify farm animal response, from an welfare point view, these can be categorized as invasive non-invasive approaches. The concept approach assess primarily looks...
The aims of the present study were to perform single-step genomic predictions in dual-purpose German Black Pied cattle (DSN) breed considering a DSN specific SNP chip (DSN_200 K), and use corresponding estimated breeding values (EBV) ongoing optimum genetic contribution (OGC) selection. All results compared with application commercial Illumina BovineSNP50 BeadChip (50 K). traits interest (due differing history these past) included 305-day lactation protein percentage (Pro%) 9029 cows,...
Crossbreeding is successfully implemented worldwide to improve animal productivity and adaptability. However, recurrent failures of crossbreeding programmes in African countries imply the need design effective strategies for predominant smallholder production systems. A comprehensive simulation procedure mimicked body weight (BWL) tick count (TCL) incidence a local taurine cattle breed an exotic indicine beef (BWE TCE, respectively). The two breeds were crossed produce F1 rotational animals....
Tail docking is still used in pigs to reduce the prevalence of tail biting, although it purely symptomatic and contrary animal welfare. Genetic selection for shorter tails might, however, help avoid has therefore been proposed. A genetic basis length known many species. Variability length, including moderate heritability, also demonstrated pigs. The aim present study was identify markers define candidate genes. To this end, 140 piglets were phenotyped genotyped at 3 days age a genome-wide...
Abstract Background Assuming that tail length is associated with the prevalence of biting, attempts are being made to shorten tails by genetic selection in order avoid painful procedure docking. However, undesirable side effects such as kinky and inflammatory changes may occur. The aim present study was clinically quantify a population known segregation length, i) its variability, ii) possible associations kinked iii) kinks inflammation using 348 piglets at day 3 (undocked) 39 (docked tails)...
The present study aimed to investigate non-genetic sources of variation milk production and quality traits dual-purpose Original Brown (OB) cows farmed in Italian alpine region by using test-day records (n = 4034). Except for yield somatic cell count, all phenotypes were predicted from mid-infrared spectra included traditional composition traits, coagulation properties, casein fractions, minerals fatty acids. Data analysed a mixed linear model which calving season, parity, stage lactation...
ABSTRACT The aim of the present study was to infer phenotypic responses and genetic parameters F1 calf diseases diarrhoea (DIAR) pneumonia (PNEU) in dependency prenatal maternal health status (PMHS) dam herd‐calving year. PMHS considered diagnoses for cow disease mastitis (MAST) claw disorders (CD) during gestation F0 dams. Furthermore, 305‐d milk production traits offspring from either healthy or diseased groups were compared. comprised 20,045 female calves (F1 = generation 1) their...
