Abstract:

A cattle farming is a very important sector of agriculture. In the Czech Republic, both breeds with ‘combined useful’ as well as ‘meat cattle’ are breeding, but especially ‘dairy cattle’ breeds. Providing feed at the right time, in required quantity and quality is the basis of successful breeding, especially in breeding dairy cows. Automatic systems are present in almost all sectors of human activity, and livestock production is no exception. Fully automatic feeding systems for pigs or poultry are already in use. The process of milking cattle using automated milking systems is also sufficiently mastered. An interesting trend is the installation of automated feeding systems for cattle feeding. They are stationary lines that perform the following operations: they dose the individual components of the feed mixture, mix the feed mixture and distribute it to the relevant feed places. All these activities are usually done without the presence of a person. The automated feeding system Lely Vector and the conventional feeding system using feeding wagon Cernin were compared. The number of automated feed wagon runs has been monitored and then the feed consumption was compared while using automatic and conventional equipment. The aim of this paper is to evaluate the benefits of an automatic feed system with regard to the conventional feed system through a mobile feed car.

Abstract:

The article is focused on the development of the new type of broiler chicken feed, based on pea (Pisum sativum L.) and blue lupine (Lupinus angustifolius L), enriched with used dried brewer´s yeast. This composition eliminates use of soybean meal (PES) that was yet a traditional component in chicken feed. The main reason for its elimination was the using of genetically modified varieties of soybean and its relatively high price around 0.5 €uro kg-1 in Czech Republic. For milling of pea or blue lupine was used vertical (hammer) mill type Taurus, supplied by company TAURUS, for drying of used brewer´s yeast had been used drier Memmert UFE 800, final dry matter of the yeast was 88%. For pellets production were used two devices, press type JGE 120-6110 and Testmer. For the determination of physical properties of manufactured pellets (the weight of 1,000 pieces, bulk density, abrasiveness and pellet durability index PDI) were used following laboratory devices, Pellet Tester Holmen NHP and Testmer 200. Experimental activities had shown that the best results were reached using pellets manufactured on base blue lupine enriched by dried brewer´s yeast (6%).

Abstract:

Inner climate at pigsty is in strong correlation with outdoor climate and tending work. Up to now, main research has been conducted to investigate air temperature and relative humidity, in order to be able to offer solutions to pigsty ventilation. At the same time, little data can be found about pigsty air gas content depending on pigs’ function work. With the aim of investigating the impact of outdoor climate and tending work on the inner climate at a pigsty of fatlings and youngs, the research was conducted to measure the air temperature, relative humidity and the content of oxygen, carbon dioxide and ammonia at these pigsties in winter time diurnally at the height of 1.5 meters. To measure the inner climate, Data Logger, appropriate sensors and the computer program PC AMR Win Control were used. At the same time, the winter outdoor air temperature and relative humidity were measured using Rotronic logger. The results of the research presented in the article concern the air temperature and velocity, relative humidity and the content of oxygen, carbon dioxide and ammonia of the working environment, measured in different places and heights of the room during daytime and diurnally above the pigpen. It became evident that the pigsty’s inner air temperature was within the extent recommended, but the air relative humidity increased partly very high. The carbon dioxide content partly exceeded the established limits. The average measured ammonia also exceeded the limits in some cases but always increased during the tending work.
