Welcome to Website of Institute of Animal Science!
Institute of Animal Science (IAS) Prague – Uhříněves is a public research institution founded by the Ministry of Agriculture of the Czech Republic.
Since its foundation in 1951, the Institute has been a centre of research into biological and bio-technological basis of animal science.
IAS carries out basic and applied research focusing on innovation and the practical use of knowledge in animal science. Eight research departments perform research in the fields of animal genetics and breeding, bio-technology and reproduction, nutrition, quality of products, animal ethology and welfare, breeding technology, herd management and production economy.
In addition to basic and applied research, IAS carries out other expert activities. One of the most significant is the implementation of the National Programme for Conservation and Utilization of Farm Animal Genetic Resources. In 2016, the IAS was appointed as the National Centre for Genetic Resources to coordinate and implement the National Programme, along with many stakeholders. The Institute has also provided for the activity of the Scientific Committee for Animal Nutrition and was entrusted by the Ministry of Agriculture to represent the Czech Republic in the European Federation of Animal Science (EAAP). IAS provides professional training on classification of swine and cattle carcasses according to SEUROP, under a contract with the Ministry of Agriculture.
Scientists from National Research Institute of Animal Production (NRIAP) in Poland, Agro Management Tools of Wageningen University and Research Centre (AMT-WUR) in the Netherlands, Lithuanian University of Health Science (LUHS) in Lithuania and Agricultural Institute Stara Zagora in Bulgaria visited the Institute of Animal Science in Prague from 10 to 12 April 2018 withinČíst dále
Growth, feeding efficiency, carcass traits, and meat quality (including as measured by sensory analysis) were examined in four cattle breeds differing by age at maturity and purpose of production. A total of 40 bulls of Aberdeen Angus (AA), Gascon (GS), Holstein (HO), and Fleckvieh (FL) breeds were fattened under identical housing and feeding conditions until slaughter at a similar age of 17 months. Whereas no breed difference was found in growth rate, dry matter intake was higher in AA and HO than in GS and FL (P < 0.001). The highest residual feed intake indicating the lowest feeding efficiency was observed in HO (P < 0.001). The highest killing-out and total lean meat proportions were found in GS, the lowest in HO and intermediary in AA and FL (P < 0.01). Lower shear force values indicating more tender meat were measured in grilled meat samples of AA than in HO (P < 0.05), with GS and FL being intermediary. Meat from AA and HO had highest concentrations of dry matter and intramuscular fat (P < 0.001). Most sensory attributes were rated higher in AA compared to the other breeds (P < 0.001). GS samples received the second-best scores (P < 0.001) for tenderness and residue. The study revealed clear differences among breeds in most of the traits examined that may be of value for beef producers. Whereas purebred GS bulls were superior in slaughter and carcass traits, eating quality characteristics were rated highest in AA.
The Scientific Committee for Animal Nutrition was established in 2002 as an advisory body of the food safety coordination group. Its main task is to prepare scientific studies, offer expert views, and prepare proposals for measures ensuring safety throughout the entire chain of food and feed production.
Human population is exposed to a broad spectrum of endocrine disruptors. Bisphenol A (BPA) are one of the group that is widely used in items of daily needs. BPA has previously been shown to negatively affecting human reproduction and usage of assisted reproductive technology (ART). However, substitution of BPA by alternative BPs brought serious problems, such as unproven harmlessness of other BPs (BPS, BPF, BPAF) and possible interactions of individual BPs in organism. Moreover, the molecular mechanism of BPs negative effect and real impact on human reproductive health remains unclear. We hypothesize that human population is exposed to BPs, negatively affecting human reproduction. The aim of the project is a) to describe a relationship of BPs' level in human seminal plasma/follicular fluid and ART outcomes and b) to describe mechanism of BPs' action experimentally, using models (i.e. mouse, pig and human follicular cells). The estimation of BPs' risk for human reproductive health and description of molecular mechanism will become a background for the solution of the BPs' problem. Project objectives 1) The biomonitoring of human population; a) the detection and quantification of BPs in seminal plasma and follicular fluids of patients undergoing the ART, b) the correlation analysis of BPs' content in the fluids with sperm quality and outputs of ART, c) the survey of the influence of anamnesis, profession and life style on BPs' exposure based on evaluation of questionnaires. 2) The study of biological models for evaluation of individual BPs' (with emphasis on bisphenol detected in Task 1, including a combination of BPs) on molecular mechanism. Human follicular cells will be included onto the index of the biological models for BPs study; a) to evaluate the effect of in vivo BP exposure on testis histology and sperm quality of mice, b) to evaluate the effect of in vivo BP exposure on quality of ovaries and oocytes of mice, c) to evaluate the effect of BP on embryonic development of mice, d) to evaluate the effect of BP on time course of pig oocyte maturation and assessment of the expansion of cumulus cells, e) characterization of BPs' target systems (on mRNA and protein level) in matured oocytes of mice and pigs, f) to evaluate the BPs effect on viability of human follicular cells.
Design new and improve existing systems and technologies for the production of quality forage by extending the precision farming features in the field of crop production to their harvest, storage and use in cattle nutrition. Develop software for the evaluation of forage quality using the fast and inexpensive NIRs spectrometric method. Update NIRs calibration equations according to chemical analysis results. Set up devices to respond appropriately to dryness, nutrition, and fodder processing level, and indicate the need for intervention, or automatically change eg the dose of silage preparation or the length of TMR mixing in the feed wagon. The targets will be met by 2022.
Improvement of reliability of national-wide evaluation of dairy cattle by increasing of reference population with SNP genotyping of cows with domestic production. Connected are economic optimization of sampling sources of DNA in herds for chips and NGS technologies, modification and imputation of data from chips to the unified format, allowing comparison of individuals and interface of parentage verification and tests of status of genes connected with health and production (today tested separately by STR technologies). Further population studies on SNP and verification of differences on DNA levels between domestic cow and imported sires populations (groups for BLUP). The final goal is the algorithm of prediction of genomic enhanced breeding value (GEBV) exploiting all genotyped animals.
