The experiment was conduced on 36 calves, aged 2 to 3 weeks. Twenty calves were transported for 2,5 hours in a trailer drwn by tractor and another sixteen formed the control group. The concentration of total protein and urea as well as the activity of cathepsin, LAP, GGTP, AspAT and A1AT were determined in blood serum taken 1 hour before transportation and 1 hour and 1, 4 and 7 days after transportation. The analysis of the obtained results the significant (P 4 0,05 and 0,01) influence of transportation stress on the level of urea and the activity of cathepsin, LAP, AspAT and A1AT in blood serum. No modification of total protein content and GGTP activity was observed.
Przemiany białkowe i aminokwasowe u cieląt w okresie neonatalnym. Cz. IV. Wpływ wielokrotnej stymulacji kory nadnerczy i uwalnianych glikokortykoidów na poziom składników i aktywność wybranych enzymów w surowicy krwi cieląt

The effect of endogenous cortisol on protein and aminoacid metabolism was studied in calves of 1 - 21 days age. The calves were treated with Synacthen N.V. Organon Holland - possessed activity ACTH - in dose 0,007 mg/kg mass body, intravenous injected. The concentration of cortisol, total protein, urea and activity LAP, GGTP, AspAT, A1AT were determined in samples serum taken before injection and after 90 min. and 8, 24, 48, 72 hours. There were observed two kinds of reactions: 1) rapid and high changes of the level of determined components, indicateing on increase catabolic processes of the proteins organism, 2) lack this kinds of changes, increase enzymes activity assuring enough free aminoacid for adaptation proteins synthesis.

The investigation aimed at the indication of the intensity changes of sounds emitted by bee colonies at various biological stages in longer time intervals. Observations were conducted in 1989 in a rearing colony and 30 small colonies. The computer system of measurement and analysis of sound applied in the investigations provided for the continuous recording of sounds applied by bees. It has been established that: 1. Biological stadges of a bee colony when different from normal (egg laying queen) are characterized by a higher frequency of the emitted sounds (above 170 Hz); 2. As time passes, beginning with a queenless stage, throughout larva, pupa, unfertilized queen till the egg laying, the frequency drops from 650 to 170 Hz; 3. The lower frequency of sounds, the higher is the probability that the colony approaches or is in a stage of biological equilibrium. Normal stages of the bee colony are accompanied by sounds of the frequency higher than 170 Hz. The lower frequency, the higher is the probabilfty than the approaches or is in a stage of biological equilibrium.

The purpose of the study was to determine the level of essential performance traits for lambs originated from single or double litters and to analyse usefulness of twins as a breeding material for meat-type center of Polish Merino. There were carried out three experiments which involved 563, 449 and 511 lambs respectively. They were divided into groups according to their sex (young ewes and young rams) and type of birth (singles and twins). Lambs body weight at the different age, the mass of wool and Ist staple length at the I controlled shearing, values of selection factors observed in meat-type centers were subjected to analysis. The lambs originated from single litters were significantly heavier from birth to the age of 6 months in young rams group and up to the age of 12 months - in young ewes group. The mass of wool and staple length at the Ist I shearing were keeping on a standard level for breeding Merino flocks and there was no difference resulting from the type of birth. The essential selection factors for singles were higher than these for twins but differences recorded did not reach statistically significant values. The lambs originated from twin litters in spite of periodically lower body weight developed properly and complied with . requirements made for young animals breeding in meat-type centers.
Masa ciała a wielkość czaszki kaczorów mieszańców kaczora piżmowego z kaczką pekińską

A total of 40 male hybrids aged about 9 months being an offspring of Musk duck males and Pekin duck females were studied. After weighing the birds, they were decapitated and their heads macerated. Eight linear cranial measurements were taken and the neurocranium volume (brain size) determined. In addition, the foramen magnum area was calculated. Within the population studied, the body weight was found to vary more than did cranial dimensions and the foramen magnum area.
Correlations between the cranial dimensions studied and body weight were in most cases Positive and highly significant. Moreover, cranial dimensions showed stronger correlation with each other than with the body weight.
Neither the body weight, nor cranial dimensions showed any significant relationship with the foramen magnum size and area.
