Kad išsilaikyti rinkoje, gauti kuo geresnės kokybės kailiukus su kuo mažesne jų savikaina, o tuo pačiu gauti ir maksimalų pelną, kreipiamas labai didelis dėmesys laikymo sąlygoms. Šinšilų laikymo sąlygos yra specifinės ir iš augintojų reikalauja tam tikrų žinių. Individualus ir šių žvėrelių šėrimas. Geram kailiui gauti reikia vykdyti pilnavertį šėrimą. Šerdami nepakankamai subalansuotais pašarais, neužauginsime geros kokybės ir atitinkamo dydžio kailiuką turinčias šinšilas. Darbo tikslas – išanalizuoti šinšilų šėrimą, laikymą, patelių pieningumą, augimo spartą, naudojant skirtingus pašarus; nustatyti maisto medžiagų pasisavinimą šinšilų virškinamajame trakte. Darbo uždaviniai: 1. išanalizuoti šinšilų fiziologines savybes; 2. nustatyti pašarų maistinę ir energinę vertę; 3. nustatyti racionų maistinę ir energinę vertę; 4. atlikti virškinimo bandymą su suaugusiomis šinšilomis; 5. nustatyti išmatose esančias nesuvirškintas maisto medžiagas ir energijos kiekį; 6. sekti jauniklių augimo spartą nuo atsivedimo iki atjunkymo; 7. nustatyti patelių išskiriamo pieno kiekį per parą. Iš atlikto bandymo ir stebėjimų galime padaryti šias išvadas: 1. trijų savaičių amžiaus tiriamosios grupės šinšilų jaunikliai svėrė 156,8 g, arba 14,48 proc. daugiau (p<0,001) palyginti su kontrolinės grupės žvėreliais, praėjus dar dviems savaitėms, svėrimo rezultatai parodė, kad tiriamosios grupės gyvūnėliai svėrė po 204,2 g, arba 11,81 proc. daugiau (p<0,001) palyginti su kontrole; šinšiliukus atjunkėme...

The goals: - to analyze the physiological characteristics of chinchillas; - to determine nutritional and energy value of diets; - to carry digestibility experiment with adult chinchillas; - to determine undigested food materials and energy in the stool; - to follow the growth rate of pups from birth to weaning; - to determine the amount of milk in female per day. Research methods. We use to fulfill the objectives set out the approach adopted in compliance with all requirements and standards. Animals are chosen for analog approach, where the difference between the parameters allowed 3 percent. Before the test, producing animals are examined by veterinarian, as well as conducted by the accounting ledgers, check or animals vaccinated against the disease peculiar to them (Januškevičius, 1992). Each group was selected of 3, has been awarded the two analogue groups. Digestibility of the test were taken from each group, all females; test performed one month after weaning pups. Pup weight, determined at the beginning of the test, in between individual growth and at the end of the test. Chemical analysis of feed and feed ingredients for individual tests was done at the Lithuanian Veterinary Academy, Department of Animal Nutrition. Results. Three-week-old chicks chinchilla experimental group weighed 156.8 grams... [to full text]

This thesis deals with the theoretical part of the explanation of basic terminology, defines alkohol, partitioning and describes the reaction time. The practical part is devoted to a comparison group of homogeneous reaction time after drinking alcoholic beverages descriptive method. Based on these data, the comparison can evaluace how much influence alkohol has on the human reaction in practice.

The thesis deals with a current issue of the relationship between pharmaceutical manufacturers and physicians. Its objective it to find out the influence pharmaceutical companies exercise on a physician decision making on providing health care, what influences physicians´ medication selection and whether there are differences in individual physicians´ specializations. Based on the findings of the research the thesis aims at creating suggestions of changes in legislation concerning the relationship between a physician and a pharmaceutical company and the establishment of new rules. The introductory theoretical part describes the role of a physician and pharmaceutical companies in the current health care system. In the practical part the method of qualitative research, characteristics of the research database and results of standardized interviews using direct quotations are presented. Discussion is focused on comparing the research results with the views of media articles and the own opinion of the thesis writer. In the conclusive part of the thesis existing rules are described and the writer recommends some measures which may lead to changes in public attitudes. Another issue, which goes beyond this thesis and could become a topic for further research, is also outlined. Based on the collected data, in the closing part of the work a hypothesis for a potential quantitative research is stated. The contribution of the thesis is based on the possibility of clarifying complicated relations between physicians and pharmaceutical manufacturers both for professional and general public.
