Data obtained from 50 individual published studies recording water intake by dairy cattle were utilized in a meta-analysis to develop a prediction equation for free water intake (FWI). Studies were selected based on quantitative measurements of DMI, diet DM%, water intake (WI), and milk yield. Many of the studies determined FWI on multiple treatments resulting in 116 mean data points from the 50 studies. With the addition of Na in the meta-analysis, 40 data points were available from the studies to examine the effects of Na on FWI. The effects of DMI, ration water intake (RWI), and milk yield (MY) were used to develop a FWI prediction equation from the 116 data points. The effects of DMI, RWI, MY, and sodium intake were used to develop a second prediction equation from the 40 data points. These equations were then compared with five published FWI prediction equations from Castle and Thomas (1975), Dahlborn et al. (1998), Little and Shaw (1978), Murphy et al. (1983) and Stockdale and King (1983). This data set showed that the five published equations either over or under predicted (P < 0.05) FWI when compared the actual FWI calculated from the meta-analysis data points. It also showed that the equation developed from the meta-analysis data points is the more accurate in determining FWI from the data points selected from the studies. A second project was conducted with the fresh water data collected from 13 freestall (FS) and 11 dry lot (DL) Kansas dairies over a 10-year period (2000-2009). Fresh water was recorded from water pumping records. Data were first summarized annually by operation and then converted to a per cow per day basis prior to analysis. Data were then analyzed by using the mixed procedures of SAS. Fixed effects included in the model were dairy type (FS or DL) and year was considered a random effect. The DL dairies averaged 186 L/cow per day and were lower than the FS dairies which averaged 237 L/cow per day. Differences between DL and FS style dairies may have been due to differences in parlor fresh water usage or cow cooling systems.

Full textGenetic evaluation systems are in rapid development worldwide. In most countries, “traditional” breeding programs based on phenotypes and relationships between animals are currently being integrated and in the future might be replaced by the introduction of molecular information. This thesis stands in this transition period, therefore it covers research on both types of genetic evaluations: from the assessment of the accuracy of (traditional) international genetic evaluations to the study of statistical methods used to integrate genomic information into breeding (genomic selection). Three chapters investigate and evaluate approaches for the estimation of genetic values from genomic data reducing the number of independent variables. In particular, Bonferroni correction and Permutation test combined with single marker regression (Chapter III), principal component analysis combined with BLUP (Chapter IV) and Fst across breeds combined with BayesA (Chapter VI). In addition, Chapter V analyzes the accuracy of direct genomic values with BLUP, BayesA and Bayesian LASSO including all available variables. The results of this thesis indicate that the genetic gains expected from the analysis of simulated data can be obtained on real data. Still, further research is needed to optimize the use of genome-wide information and obtain the best possible estimates for all traits under selection.

Full textLa fiebre Q es una zoonosis re-emergente endémica mundialmente, causada por Coxiella burnetii, un bacilo Gram negativo intracelular. Los rumiantes domésticos son el reservorio principal para los humanos. La infección es principalmente asintomática en bovino, pero se la ha relacionado con desórdenes reproductivos. El objetivo de esta tesis fue proporcionar información para mejorar su control en las explotaciones bovinas. Se estudiaron la serología, los patrones de excreción de C. burnetii y su relación con el rendimiento reproductivo de las vacas lecheras. Además, se evaluó la bioseguridad de una vacuna inactivada contra C. burnetii fase I aplicada en vacas gestantes y su capacidad para mejorar el rendimiento reproductivo. Las conclusiones son que no se detectaron anticuerpos precalostrales en terneros de madres infectadas, excreción y seropositividad no se relacionaron negativamente con el rendimiento reproductivo y que la vacunación de vacas en gestación avanzada no reduce la excreción pero mejora el rendimiento reproductivo.
Q fever is a worldwide re-emerging zoonosis caused by an intracellular Gram negative bacillus, Coxiella burnetti. Domestic ruminants are the main reservoir to humans. Despite the infection is mainly asymptomatic in cattle, is has been linked with reproductive disorders. Therefore, the aim of this thesis was to provide information about C. burnetii infection to improve its control in dairy herds. A study of serological profiles, shedding patterns and its relationship with reproductive performance has been performed. In addition, a C. burnetii inactivated phase I vaccine has been tested evaluating the biosafety for use in pregnant cows and in assessing its ability to improve reproductive performance in dairy herds. The results indicate no detectable precolostral antibody response in calves born from infected dams, seropositivity and shedding are not related to reproductive disorders and vaccination of advanced pregnant cows was not able to reduce bacterial shedding but improves reproductive performance.
