Neosporosis is an infectious disease of cattle and other species with a worldwide distribution. In Poland, the seropositivity rate for N. caninum among dairy cattle varies between 6% and 80%, with the highest number of seropositive cows in central and north-eastern voivodeships. In the United States, in 2003 the total annual cost of N. caninum infections was 657 million dollars, and in Great Britain...
Epibionts of ornamental freshwater shrimps bred in Taiwan. One of the major problems in breeding Neocaridina davidi in Taiwanese aquaculture ponds are epibionts found on the body of ornamental shrimp. These organisms affect shrimp wellbeing by causing distress which leads directly to shrimp weakness, loss of colour and even casualties. They can also be observed in imported shrimps which put in danger...
Effect of Bacillus subtilis and Bacillus licheniformis inclusion in turkey diets on growth performance.The aim of this study was to evaluate the influence of a probiotic preparation containing spores of Bacillus subtilis and Bacillus licheniformis, added to feed, on growth performance of female turkeys reared until 84 days of age. A total of 300 day-old Hybrid Converter female turkeys were randomly...
The paper shows that rational management of game populations is a set of breeding practices. These mainly involve creation of appropriate conditions that will be most beneficial for normal development and reproduction of animals. However, game breeding is considerably more difficult and hunters face problems that differ from those encountered by breeders of domesticated animals. This part is focused...
Use of hop cones in growing beef cattle nutrition. The objective of this study was to determine the effect of the supplementation of bull diets with hop cones on growing bull performance, the concentrations of blood analytes, including liver enzymes. Twenty-four growing bulls of Slovene autochthonous Cika breed (BW 373 kg; age 329 days) were randomly allocated to 6 pens (4 animals/pen). Before the...
Analysis of the weaned piglets reaction on the handling material with colored balls and possibility of exploration and chewing. Maintaining proper pig welfare levels in intensive production systems requires the use of appropriate handling materials. At present, there are many elements commonly referred to as "toys" in breeding and production, but not all of them meet safety and functional...
Birds and bats using buildings as a place of breeding or shelter.The presence of birds and bats was analysed in buildings intended for thermal refurbishment. Study material was collected in the years 2012-2016 in 336 buildings from 11 voivodships. For detailed analyses concerning birds, data from three voivodships were selected: kujawsko-pomorskie, łódzkie and mazowieckie. To determine differences...
Analysis of genetic structure of Silesian horses from National Stud. The aim of the study was to analyze the genetic composition of Silesian horses bred in "Książ" National Stud basing on their pedigreesand to try to answer the following question: is the subdivision of Silesian horse population really necessary to prevent local horse breed? As the material 72 pedigrees of brood mares and...
Influence of application of (1,3)-(1,6)-β-D-glucans and mannans on production results of sows and piglets. The aim of the study was the assessment the production results and health status of sows and their offspring modulated by supplementation of (1,3)-(1,6)-β-D-glucans and mannans. The experiment was carried out in farrowing and nursing sector.It was performed using crossbreed (Polish Large White...
Effect of liquid acidifiers on rearing performance of suckling piglets.Crossbred piglets from 36 litters (12 litters each in control group C and in experimental groups E1 and E2) were investigated. From birth to weaning at 28 days of age, piglets from group E1 received drinking water with a 2% solution of lactic, formic and orthophosphoric acids, and those from group E2 a 0.05% solution of Baracid...
Polish crossbred pigs’ blood haematological parameters depending on their age and physiological state. Based on the assumption that factors such as age or physiological status may have a significant effect on the haematological parameters of pigs’ blood, the aim of this paper was to present how the values of basic haematological parameters of the blood of crossbred Polish Landrace x Polish Large White...
Genetic associations of reproductive traits in pigs. In the field of genetics, one of the main research area in relation to animal reproduction is the identification of genes or genomic regions influencing reproductive phenotypes. The genes analysed for the determinants of their fertility are among other: LEP, PRL, PRLR, RBP4. With the use of genetic markers, it is possible to identify of both males...
Effect of dietary arginine supplementation on body weight changes and productivity of sows.The objective of this study was to determine whether provision of additional arginine to pregnant and lactating sows could influence body weight changes in females during reproductive cycle as well as reproductive and rearing performance of the piglets. The study included 36 F1 crossbred sows (Polish Landrace...
