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.


Alfalfa meal as a source of carotenoids in combination with ascorbic acid in the diet of laying hens

The purpose of the experiment was to determine how the addition of dehydrated alfalfa (DA) and ascorbic acid (AA) into the diet of hens influences the performance characteristics and egg quality characterised by physical parameters, yolk carotenoid content, and the oxidative stability of yolks. Two hundred and forty Hisex Brown hens were divided into 6 treatment groups according to the level of DA (0 and 40 g/kg) and concentration of AA (0, 100, and 200 mg/kg) in the diet. Hen-day egg production and egg mass production were reduced by the supplement of DA (P < 0.001) and AA (P = 0.017). The addition of DA itself increased the feed intake per egg (P < 0.001) and the feed conversion ratio (P < 0.001). The heaviest eggs (P < 0.001) were laid by hens fed a diet with 100 mg/kg of AA (67.6 g). The AA supplement improved egg content quality, i.e., Haugh units (P < 0.001), albumen index (P < 0.001), and yolk index (P < 0.001), whereas the addition of DA increased values of yolk colour (P < 0.001) and had a negative effect on shell quality. The interaction of DA and AA was detected in the zeaxanthin concentration in the yolks (P = 0.002). The highest concentration was found in eggs from hens fed a diet with a DA supplement and 100 or 200 mg/kg of AA (17.33 or 17.25 mg/kg dry matter of yolk). In addition, 40 g/kg of DA significantly increased the concentration of other carotenoids, lutein (P < 0.001) and β-carotene (P < 0.001) in the yolks and increased the oxidative stability of fresh eggs (P < 0.001). The results suggest that adding DA in the amount of 40 g/kg to the hen diet provides a good source of carotenoids and, in combination with AA, a better deposition of carotenoids in egg yolks. On the other hand, DA deteriorates performance and shell quality.

Scientific Committee for Animal Nutrition                                                                                                                       

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.


Family-type pig rearing with insemination of lactating sows

The aim of the innovation project is to enhance effectiveness of insemination system and increase reproduction parameters under the conditions of organic pig husbandry. The method of group insemination of lactating sows, which is suitable for organic and alternative pig herds, has its origin at the Swiss FIBL Institute and has been practised in the Biofarma Sasov organic herd for than 10 years. Biofarma Sasov is the only farm in Czechia where this method of inseminating sows during lactation has been implemented on a commercial scale. The goal of the collaboration is to evaluate the existing farm data sets statistically with the aim of finding the most effective way of running this husbandry system while making maximal use of the farm resources. Recommendations resulting from the project will be implemented on the farm, thus securing an optimal utilization of this method under the specific conditions of organic pig husbandry.
