The aim of this paper is to estimate the influence of different breeds on rabbit growing and physiological indicator. The temperature of our investigated rabbits varied from 37.6 ºC to 38.8 ºC when the environmental temperature was 18 ºC. Good dental health and a perfect 'bite' help to assimilate feeds nutrients. The fur of all rabbits was clean, sleek and not matted. The average weight varied from 3.7 kg to 4.05 kg. Referring to various Lithuanian and foreign sources it turns out that there is no fixed hematological standards subjected to different breeds. Usually it is said that the quantity of cholesterol is 0.14-1.86 mmol/l, glucose – 2.78-5.18 mmol/, triglycerides – 1.38 mmol/. The state of health can be evaluated according to rabbits’ behavior. The author (Solar, 2001) makes out the main behaviour observation stages. With reference to these guidelines we have estimated that New Zealand rabbits’ eating and drinking in 1-hour period during the day made 20%, moving – 10%, rest – 70 %, no cecotrophy was observed. If to compare French Giant rabbits the periods were 33%, 37 % and 30 %. Conclusions:1. The rabbit growing has increased 22.8% during the last three years and the number of a herd of breeding rabbit has increased 13.7%. Italy provides about 40.7% and Spain 20.3% of rabbit meat for world market. 2. The White New Zealand and French Giant rabbits that were fed on industrial crops were healthy and blood index was within the mark. 3. The quantity of glucose, cholesterol... [to full text]
