The report describes a unique case of newborn conjoined twins in guinea pigs (Cavia aperea f. porcellus). Connected twins in guinea pigs have been very rare, and there are only a few previous reported cases. The newborns were stillborn in breeding in the Czech Republic in 2020 as two bodies conjoined into one. The external and internal structure of...

Passive transport of colostral immunoglobulins is essential for calves to maintain optimal health. There are many factors that influence the absorption of immunoglobulins such as colostrum density, timing of ingestion, volume of colostrum but also the method of feeding. This study compares two manners of feeding calves – the esophageal tube feeder...

The target of the research was to analyze the effect of antidiarrheal feed additives on calves average daily weight gain. In the study, 120 calves were analyzed. Newborns were selected into 3 treatment groups, control (without supplementation) and group with Ascophyllum nodosum (prebiotics), and mixture of Lactobacillus sporogenes, Enterococcus fae...

Current experiments with farm animals showed that it is possible to use grape by-products as a source of nutrients in animal nutrition. In the present experiment, we hypothesize that one reason for the variation among feeding trials, besides production steps affecting byproduct quality in winery, the variation among cultivars may have substantial c...

The aim of this study was to determine nutrients content of 4 oilseeds (sunflower, soybean, flaxseed and rapessed) and fatty acid profile of oils obtained from the seeds. Dry matter (DM), crude protein (CP), nitrogen free extract (NFE) and fat content of the seeds were determined by standard laboratory methods and procedures. Significant (P

The most frequent canine perineal tumour is the perianal (gland) adenoma (also known as the circumanal adenoma or the hepatoid adenoma). Tumour markers are substances that are produced by the body in response to cancer, or may be produced by cancer itself. Carcinoembryonic antigen (CEA) and tissue polypeptide specific antigen (TPSA) are tumour anti...

The occurrence of coccidiosis is an enormous problem of pheasant farming. The aim of this study is to show, that this disease can be cured by unconventional dietary supplements. Dietary supplements which were used in this study were as follows: prebiotics (Ascophyllum nodosum), probiotics (Lactobacillus thermophilus) and homeopathics. Four groups o...

The aim of this study was to prove the hypothesis that the growth and health of calves are dependent on feed supplements with an antidiarrhoeic effect, in relation to sex, season of birth, and number of the dam's lactations. A total of 186 calves were included in the experiment. After birth the calves were divided into three treatment groups: Ascop...

Healthy and strong individuals are fundamental in every cattle breeding.
