The perception of risks due to climate change by farmers and the measures they take address those are paramount importance in policy-making if implementations targeted adaptation mitigation strategies be economically environmentally sustainable. This study focused on Tunisian dairy farmers' perceptions actions taken cope with changes attributable change. Using a bottom-up approach, 566 surveys were carried out randomly among throughout Tunisia. A total 70 diagnostic variables relating farm...
The aim of this study was to estimate phenotypic and genetic correlations between methane production (Mp) milk fatty acid contents first-parity Walloon Holstein cows throughout lactation. Calibration equations predicting daily Mp (g/d) (g/100 dL milk) were applied on mid-infrared spectra related recording. A total 241,236 predictions acids used. These data collected 5 305 d in 33,555 from 626 herds. Pedigree included 109,975 animals. Bivariate (i.e., a trait) random regression test-day...
Abstract. Multi-trait Bayesian procedure was used to estimate genetic parameters for reproductive traits in Tunisian Holstein cows. A total of 31 348 lactations the calving years 2005 2012 were analyzed. Fertility interval (CI), days open (DO), first insemination (DFI), from conception (FIC), and number inseminations per (NI). Posterior means heritabilities CI, DO, DFI, FIC, NI 0.047, 0.03, 0.025, 0.024, 0.069, respectively. repeatabilities same respective 0.106, 0.094, 0.051, 0.036, 0.17....
This study reports on the exploration of temporal relationships between milk mid-infrared predicted biomarkers and lameness events. Lameness in dairy cows is an issue that can vary greatly severity concern for both producers consumers. Metabolic disorders are often associated with lameness. However, arise weeks or even months after metabolic disorder, making detection causality difficult. We already use technology to predict major components, such as fat protein, during routine recording...
First-lactation test-day (TD) milk records of Luxembourg and Tunisian Holsteins were analysed for evidence genotype by environment interaction (G x E). The joint data included 730 810 TD 87 734 cows 231 common sires. Random regression sire models with fourth-order Legendre polynomials used to estimate genetic parameters via within- across-country analyses. Daily heritability estimates yield from within-country analysis between 0.11 0.32, 0.03 0.13 in Tunisia, respectively. Heritability...
The segregation of the causal mutation (mh) in muscular hypertrophy gene dual-purpose Belgian Blue (dpBB) cattle is considered to result greater calving difficulty (dystocia). Establishing adapted genetic evaluations might overcome this situation through efficient selection. However, heterogeneity dpBB populations at mh locus implies separating major and other polygenic effects complex modeling. use mixed inheritance models may be an interesting option because they simultaneously assume both...
We investigated the use of different Legendre polynomial orders to estimate genetic parameters for milk production and fatty acid (FA) traits in first lactation Walloon Holstein cows. The data set comprised 302,684 test-day records yield, fat protein contents, FAs generated by mid-infrared (MIR) spectroscopy, C16:0 (palmitic acid), C18:1 cis-9 (oleic LCFAs (long-chain FAs), SFAs (saturated FAs) UFAs (unsaturated were studied. models included random regression coefficients herd-year calving...
