It was proved many times that the selection leaded in the direction of one trait can also influence on other. One of the most frequently selected trait is body weight which is easy to measure. In this experiment, mice from three lines were used. Two of them were divergently selected on body weight at the postnatal day 21 (light and heavy lines) for over 135 generations. The third line were the control line without any selection. The animals were observed in the social testing apparatus which is used for perform two behavioral tests: sociability and preference for social novelty tests. The results show that selection on body weight influenced the social behavior of laboratory mice. Individuals from the heavy line (both sexes) showed minor modifications of the natural behavior in the sociability test (P<0.05). Additionally results of females from the heavy line demonstrated some disorders in social novelty test (P<0.05).

The study was conducted in order to verify the hypothesis of the sedative effect of the preparation FELIWAY® in the prophylactic examination in a veterinary clinic. It was a double-blind placebo controlled study. The examined population consisted of 48 cats, of different breeds, sexes and ages. Analysis of the results showed that preparation had no effect on limiting the stress and animals were calmer during the test phase with placebo (P=0.028). Stratification of the results showed that the degree of stress during the test was related only to the age of the cat (P<0.001).

Pheromones as signal compounds play an important role in the lives of all animals. Studies of their properties prove the great importance of these compounds in animal intraspecies communication. Especially significant is the role of these compounds in animals with a highly specialized sense of smell, such as the feline and canine families. Thanks to the research on domesticated representatives of these families, the domestic cat and dog, the structures of the body responsible for the production and secretion of pheromone compounds have been described. This made it possible to isolate these substances and determine their chemical composition. This was followed by the production of their synthetic counterparts, which made it possible to broaden the spectrum of research on pheromones. The results of experiments conducted over the past few years suggest that pheromonotherapy can be used to reduce stress in animals bred by amateurs. This review cites examples of research on the reduction of the level of anxiety in dogs and cats with veterinary phobia during hospitalization and consultation in veterinary clinics. Prospects for the use of pheromonotherapy in veterinary medicine are also discussed.

A complete set of procedures comprising of the induction of haploid embryo development by pollination with irradiated pollen, embryo isolation and in vitro culture, haploid plant development, chromosome doubling by regeneration from leaf explants, acclimatization, self-pollination of DH plants and assessment of DH lines was performed in cucumber. Haploid and doubled haploid plants were obtained from all eight genotypes used in the study. The donor plant genotypes were evaluated by comparing the number of haploid embryos and DH plants obtained from each genotype. The influence of the donor plant genotype and its age on the regeneration and the yield of DH plants were evaluated. In order to optimize the method of chromosome doubling, the composition of medium was modified and the explants were divided into four groups with regard to the leaf sector used for regeneration. Acclimatization of DH plants to the greenhouse conditions was improved. Uniform, useful in breeding, DH lines were obtained.

Long-term selection for body weight, which affecting changes in life span and time of puberty, has resulted different reproductive strategy in mice divergently selected for body weight at the 21st day of age. Heavy mice (C) are typically rapidly maturing animals, with a shorter but more intense reproductive period. Light mice (L) are more long-lived so that mature later than C mice, Due to the longer period of reproduction L mice are capable of more litters, which are also less numerous. Moreover, long-term selection may changes of mice. L mice showed lower activity in the open field test. Light mice are more susceptible to stress, and they have higher excitability, than heavy mice.

On the basis of internet survey and using specially structured questionnaire for owners authors obtained data concerning assessment of behaviour of 161 domestic pure breed and mixed breed cats. Working on this data various statistical procedures were applied with Principal Component Analysis (PCA) as a chief method to extract personality dimensions in domestic cat. Authors obtained five dimensions of cat personality: openness, quietness, affiliation, activity and anthro-affiliation. The distinction between affiliation (in cat group context) and anthro-affiliation (in relation between cat and man) was firstly revealed in this study. The data also showed that some specific factors (age, duration of play with caretaker) have effect on cat personality. The comparison of personality of pure breeds and mixed breed cats referred rather to vocal communication than to its affiliation with human being (anthro-affiliation). Results of this study yielded by authors may be applied in shelters procedure of cat adoption.

Young chinchillas weight gain, depending on their body mass at birth. The aim of the study was to determine if the results of raising and growth for up to 4th months of age in chinchilla depends on body weight and the litter size at birth. There were also attempts to answer the question, when sexual dimorphism begins to be visible in young chinchillas. Males are heavier females from the first month of life in chinchilla, however up to the 4th months of age the differences are not statistically significant. During the study it was found, that young chinchillas mortality depends on their body weight at birth. When the body weight at birth is higher, the greater chances of survival of the young are. Number of puppies in the litter affects their body weight: the more young per litter are, the less average body weight is.

Preliminary study of memory processes in Mongolian gerbil (Meriones unguiculatus). Mongolian gerbil (Meriones unguiculatus) a small rodent living in the wild steppes of Mongolia was discovered in 1866 and it is becoming increasingly popular as a pet. The present work is an introduction to describe the behavior of this species and to investigate the influence of gender and age on memory process. 40 gerbils divided into four study groups (young males, young females, adult males, adult females) were twice tested in a modified version of the Lashley III maze (repeat after a week). Using statistical tests memory parameters, the activity of animals and behavior associated with the level of stress were analyzed. Conducted observations and calculations performed showed no difference between the groups (p > 0.05), which leads to the conclusion that in Mongolian gerbils age and sex have no effect on memory.
