3(1) #01 01 Mar 2000	Agronomy	MICROBIOLOGICAL ANALYSIS OF LESSIVE SOIL FERTILISED WITH ANIMAL WASTE Zbigniew Paluszak, Halina Olszewska

The present research aimed at defining the survival rate of faecal bacteria selected in the lessive soil fertilised with cattle slurry. The field trials over dry and moist summers involved slurry at the amount of 3 l^.m^-2 with the suspended matter of S. senftenberg, E. coli and faecal streptococci. Soil was sampled from different depths prior to the application of slurry, a week after the application, and then four times with monthly intervals. On average over the total soil profile over the dry period, the survival time of E. coli amounted to 17.7 weeks, faecal streptococci 18.7, while Salmonella bacilli - 14.1 weeks. Over the moist period, it was much longer and amounted to 26.7, 25.9 and 19.9 weeks, respectively. A prevailing number of faecal bacteria were retained in the upper layers of soil profiles. Over the dry period microorganisms migrated to the depth of 43 cm, while over the moist period - to 70 cm. The research showed that facing soil structural d

The research aimed at defining the variability in the yielding of yellow lupin cultivated in pure stand and in mixtures with spring triticale in a field experiment at a varied April-July rainfall as well as a varied sowing density of both components. The experiments were carried out over 1990-1993 at the Mochełek Experiment Station of the Bydgoszcz University of Technology and Agriculture, Faculty of Agriculture. The experiments were conducted on light soil of a good rye soil suitability complex, IVa soil quality classification. The value of the rainfall variability coefficient over April-July amounted to 37.1%. The driest period rainfall amounted to 106 mm, while the most moisten period rainfall - 260 mm. It was observed that the yellow lupin yielding variability in pure stand was considerably lower than in the mixtures with spring triticale. An increasing lupin sowing density from 25 to 50-100 seeds per 1 m², both in pure stand and in mixtures, showed a stabilising effect on the seed yield and pl

The 3-year field experiment researched the impact of weed control with herbicides on the chemical composition of four table potato cultivars. There were observed significant changes in the tuber chemical composition of potatoes treated with herbicides which significantly decreased the contents of dry matter, starch and phosphorus as well as increased the contents of vitamin C, total saccharides and magnesium in tubers, as compared to the object weed-controlled mechanically.

The activity of alpha-D-galactosidase and contents of soluble saccharides were studied in Juno yellow lupin (Lupinus luteus L.) seeds stored. Seeds harvested at three stages of maturity (15, 25, 35 days after flowering - DAF) were stored at 21°C for two years (frozen immediately after harvest) or were dried after harvest to 8% of water content and stored at +20°C for 5 and 6 years. A high alpha-D-galactosidase activity in maturing and mature seeds could have been one of the causes of decreasing viability and vigour of the seeds stored. The hydrolysis of raffinose oligosaccharides decreased the ratio of these saccharides to sucrose. The decrease in the content of raffinose oligosaccharides was accompanied by an increase in galactosyl cyclitol contents.

The studies were carried out in the North -West part of Poland. The investigation was conducted on 292 specimens of the Holstein cattle with added 50% of HF.The extensity and intensity of the coccidia infection were determined by means of the Willis-Schlaaf's and McMaster's methods. Six species of coccidia were found : E. bovis, E. auburnensis, E. zürni, E. ellipsoidalis, E. subspherica and E. cylindrica. Twenty seven per cent of dairy cows and 49.6 per cent of calves were infected . Number of oocysts per gram of feces in calves ranged form 333 to 2237. Observations on the dynamics of the coccidia invasion in calves during a yearly cycle exhibited the existence of two peaks; a vernal and an autumnal ones.

The study, carried out during the spawning season, involved 30 mature carp females aged 5 years. The fish were divided into two experimental groups, those belonging to one of them being injected pimozide, a dopamine antagonist. The pituitaries and pineals were removed from all the females and perifused. Perifusion was carried out in pure medium alone, in the medium in the presence of the pineal gland, and in the medium enriched with dissolved melatonin. The perifusion proceeded in 2000 lux intensity light and in total darkness. Maturation gonadotropin (GtH2) concentration in the perifusion medium pumped through columns was determined with ELISA, an immunoenzymatic technique. The experimental treatments within each group showed no significant differences (p>0.01) with respect to the GtH2 concentrations in the perifusion medium. This result can be regarded as an evidence of a lack of any direct effect of the pineal gland and/or melatonin on GtH2 secretion from the carp pituitary during spawning.
3(1) #02 01 Mar 2000	Fisheries	ATTACKS OF CYCLOPOID Acanthocyclops robustus (Sars) ON NEWLY HATCHED CYPRINIDS Waldemar G. Piasecki

Two experiments on newly hatched, 1-d-old, immobile and non-feeding larvae of carp (Cyprinus carpio Linne) and crucian carp (Carassius carassius (Linne)) were performed. Each experiment involved 3 treatments: WA (larvae + Acanthocyclops robustus); WAD (larvae + A.robustus + additional food for the cyclopoids consisting of Daphnia magna, rotifers, and ciliates); and W (larvae only; control). The carp larvae experiment took 5 days, while the crucian carp one proceeded for 6 days. During the experiments, the number of larvae in each treatment, their condition, degree of damage by A.robustus attacks as well as behaviour of both the larvae and cyclopoids were checked. The experiments demonstrated that A.robustus did attack the larvae, the attacks resulting in a considerable mortality. The mortality rate depended on the cyclopoid density as well as on the presence and quality of an alternative food supply. The attacks were most frequently effected by males and
3(1) #03 01 Mar 2000	Fisheries	THE PROBLEM OF QUALITY ASSESSMENT OF SURFACE LOTIC WATERS AS EXEMPLIFIED BY RIVERS TYWA AND RURZYCA Malgorzata Raczynska, Joanna Zurawska, Juliusz C.Chojnacki

The paper describes and compares various (chemical and biological) methods used in Poland for lotic water quality assessment; included are methods which have not been formally approved yet. Based on ecological surveys made in 1996-1998, a quality assessment of water of rivers Tywa and Rurzyca is presented. The assessment allows to conclude that application of a single method leads to a serious misrepresentation of the lotic biota. In both rivers there were sections the water of which, when assessed with physico-chemical methods, appeared much different than when assessed with biological methods in both seasons of studies.

In the study on pastes: native potato, wheat and corn and those segregated according to granule size as well as pastes of native oat special consideration was given to soluble and insoluble fractions of 2.5% pastes obtained at 90^oC. Those fractions were analysed using gel chromatography. Ratio of amylose to amylopectin in supernatant and in sediment were calculated and differences were demonstrated in molecular mass depending on starch origin.

The anatomical structure of the middle cerebral artery in domestic pig (Sus scrofa f. domestica) was defined using 88 cerebral hemispheres. It was observed that the artery ramified into ten permanent branches. Two rhinal arteries supplied the area of cerebrum on the border between the old and the new cerebral cortex. The other eight branches bifurcated into three branches going into the frontal area, two branches - the parietal area and three temporal branches which supplied the new cerebral cortex exclusively. In domesic pig, most frequently, 38.7 %, the rostral cerebral artery gave rise to two and, in 59.1%, three independent branches. In one hemisphere (1.1%) the rostral cerebral artery gave rise to one main trunk of the middle cerebral artery. Similarly in one individual there were observed six independent branches of that artery.

The course and variability of cerebral base arteries in Capra hircus L was researched in 27 cerebra. It was observed that the vascular pattern of the species researched remains similar to the pattern observed in the members of Cervidae. The features characteristic for this species include the variability of descend of the rostral choroid artery as well as of the posterior cerebral artery.

In case of small animals the endoscopic examination of the digestive tract may apply to the endoscopy of esophagus, stomach and duodenum, which is described as the examination of the anterior part of the digestive tract (panendoscopy), or may be limited to examination of rectum and colon, which is described as endoscopy of the posterior part of the digestive tract. The examination was performed in the 12 cats of European race, various sex, 2-6 years of age and divided into 2 groups. We received some interesting results: Fibroscopy of the anterior part of digestive tract is a safe and very useful diagnostic technique to recognise esophagus, stomach and duodenum illnesses in cats. Olympus XQ 20 pediatric fibroscope can be used in endoscopy of the anterior part of digestive tract in cats. Esophagoscopy might be performed with stiff endoscope, which is of little use in gastroscopy.

The aim of the studies was the influence comparison of the three kinds of blood products: brown and black dried livexes and blood meal, added to sheep forage, on total protein level, energy value, volatile fatty acids (VFA) amount, levels of carbon dioxide and methane in caecal content of the animals. The samples of caecal content were taken from the sheep immediately after slaughtering, i.e. 2,5 hrs after morning feeding. The livex and blood meal were added to the forage in the amount of 2%. During in vivo application of these nonconventional dietary supplements, the significant inhibitory livex (black and brown) effect on methane level in the sum of caecal gases (45,5% increase for black and 33,4% for brown livex, respectively). Energy of caecal content was about 30% higher in sheep fed with black livex. Respective percentage was about 40% and about 20% for the brown livex and blood meal respectively. Percent increase of protein amount was as follows: 17,9% (for black livex), 23,1% (for brown livex) and 14
