Pozycja Open Access Masa ciała a wielkość czaszki kaczorów mieszańców kaczora piżmowego z kaczką pekińską(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Pierko, Małgorzata; Szczepańczyk, Ewa; Melosik, Maciej; Akademia Rolnicza w Szczecinie, Katedra Zoologii; Akademia Rolnicza w Szczecinie, Katedra Zoologii; Akademia Rolnicza w Szczecinie, Katedra ZoologiiA 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.Pozycja Open Access Kształtowanie się wartości biologicznej białka nasion amarantusa pod wpływem ogrzewania(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Petkov, Krum; Łukaszewski, Zbigniew; Antczak, Krzysztof; Akademia Rolnicza w Szczecinie, Katedra Żywienia Zwierząt i Gospodarki Paszowej; Akademia Rolnicza w Szczecinie, Katedra Żywienia Zwierząt i Gospodarki Paszowej; Akademia Rolnicza w Szczecinie, Katedra Żywienia Zwierząt i Gospodarki PaszowejThe aim of the research was to determine the quality of amaranthus protein. Two bio logical tests were carried out on the laboratory rats (Wistar strain) fed with non - heated and heated (105°C for 20 minutes) seeds of amaranthus. Methodology requirements for this type of research were realized by the growth (PER, PERstand, NPR) and balance (Dap, Dt, BV, NPU, NPUstand) methods. The research indicates adviseable heating the seads of amaranthus and increasing their nutritive value.Pozycja Open Access Wzrost i asymetria soczewki ocznej bydła domowego Bos primigenius f. taurus w okresie płodowym(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Melosik, Maciej; Pierko, Małgorzata; Szczepańczyk, Ewa; Szuba , Zdzisław; Akademia Rolnicza w Szczecinie, Katedra Zoologii; Akademia Rolnicza w Szczecinie, Katedra Zoologii; Akademia Rolnicza w Szczecinie, Katedra Zoologii; Akademia Rolnicza w Szczecinie, Katedra ZoologiiGrowth and bilateral asymmetry of the eye lens was studied in 241 Black and White cattle fetuses examined from pregnancy day 42 until parturition. The left and right eye lenses were weighed and their equatorial diameter and thickness measured. The fetuses were divided into four groups differing in body weight: I, early fetal stage, body weight below 0.99 kg; I a, initial part of intermediate fetal stage, body weight 1.00-3.49 kg; II b, terminal part of intermediate fetal stage, body weight 3.50-7.99 kg; III, late fetal stage, body weight exceeding 8.00 kg. Possible sex-dependent differences were taken into account in each analysis. Basic descriptive statistics was determined and used to calculate symmetry and asymmetry. The highest values of fluctuating asymmetry coefficients with respect to the eye lens and linear dimensions were found at stage II b in both sexes.Pozycja Open Access Ocena postępu produkcyjnego w zakresie cech związanych z użytkowością wełnistą owiec rasy merynos polski(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Lachowski, Włodzimierz; Akademia Rolnicza w Szczecinie, Katedra Hodowli Bydła i OwiecThe goal of the studies was to compare the productivity level of dams with the productivity level of their daughters. Data from breeding records of a flock of Polish Merino sheep coming from a sheep shed at Ulikowo were used in the analysis. They included some traits of the wool type utility and the body weight at the age of 12 months of 3992 ewes born in 1977-1987. The analysis aimed at comparison of the dam groups with groups of their daughters coming from successive lambings and the daughter groups with groups of their sisters and half-sisters referred to evaluation of the productivity level within such traits as: weight of greasy fleece and weight of clean fleece from the second lamb shearing, weight of greasy fleece from the first mature shearing, point classification for fleece character, total point score from a 100-point classification and body weight of ewes at the age of 12 months. This analysis was performed in order to show the presence of the production progress. The results obtained demonstrated a positive tendency, i.e. the presence of the production progress within the studied traits. However, its value should be evaluated from the point of view of the production achieved in 1984, that is in the year when the actual and not converted data were used.Pozycja Open Access Analiza wpływu niektórych czynników na wybrane cechy użytkowości wełnistej owiec(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Lachowski, Włodzimierz; Akademia Rolnicza w Szczecinie, Katedra Hodowli Bydła i OwiecThe study was aimed at estimating the influence of main effects (genealogical group, month, year, type of birth) on selected traits of wool performance in ewes (weight of greasy wool and weight of clean fleece from the second lamb shearing and weight of greasy wool from the first mature shearing). Analysis was based on data from breeding records of the Wool Centre of Polish Merino at Ulikowo. The investigations included 3992 ewes born in 1977-1987 coming from single and twin litters and selected for replacement purposes. A significant or, more frequently observed, highly significant influence of main effects on the studied traits was found. In consequence, one might suggest to include them absolutely as a source of varability when evaluating the wool performance or to introduce suitable corrections.Pozycja Open Access Schistosomia u cieląt na terenie byłych województw: białostockiego, gdańskiego i olsztyńskiego w latach 1971-1975(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Kubasiewicz, Wiesław; Rękas, Lucyna; Akademia Rolnicza w Szczecinie, Katedra Anatomii Zwierząt; Akademia Rolnicza w Szczecinie, Katedra Anatomii ZwierzątRecords of 1971-1975 were examined referring to 64 calves with schistosomia registered on the territory of the former Białostockie, Gdańskie and Olsztyńskie Provinces. These calves make 7.1% of all cases of this type found in Poland up to 1975. The sire pedigree for the studied calves was established for 50 cases. Six bulls were found to be fathers of two calves each; the remaining calves were sired by different bull each.Pozycja Open Access Efektywność probiotyku w żywieniu loch w okresie okołoporodowym(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Jacyno, Eugenia; Pietruszka, Arkadiusz; Owsiany, Jacek; Akademia Rolnicza w Szczecinie, Katedra Hodowli Trzody Chlewnej; Akademia Rolnicza w Szczecinie, Katedra Hodowli Trzody Chlewnej; Akademia Rolnicza w Szczecinie, Katedra Hodowli Trzody ChlewnejInvestigations were carried out on 248 sows divided into two groups: control - 120; and experimental - 128. The sows from experimental group received 5g of probiotic per day for Ю days before farrowing and for 15 days during lactation. The sows receiving a probiotic produced by 0.49 more piglets than sows from the control group. The mortality of piglets from the experimental group was by 41% lower. In conse quence in this group was reared by 0.71 more piglets than in the control group. The body weight and daily gains of piglets in the rearing period were some what higher in the experimental group, too.Pozycja Open Access Współzależność między użytkowością tuczną a użytkowością rzeźną świń(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Jacyno, Eugenia; Pietruszka, Arkadiusz; Akademia Rolnicza w Szczecinie, Katedra Hodowli Trzody Chlewnej; Akademia Rolnicza w Szczecinie, Katedra Hodowli Trzody ChlewnejThe relationship between the fattening performance and slaughter traits of carcass was determined on 80 fatteners progeny of Polish Large White sows and Belgian Landrace, HampshirexPietrain, Pietrain and Polish Large White boars. There was 20 pigs of each genotyp (10 gilts and 10 barrows) in the experimental group. The animals were fattened from 23 to 100 kg of liveweight and then slaughtered for testing. The daily body weight gains were correlated highly significantly and positively with the area of loin eye, meat content in basic cuts, hind ham, and the carcass meat percentage. On the other hand, low and negative correlations were obtained for daily gains and mean backfat thickness. Highly significant positive correlations were obtained for intake of digestible protein, metabolisable energy, lysine and mean backfat thickness. Highly significant negative correlations were found for intake of digestible protein, metabolisable energy, and lisyne and the carcass meat PercentagePozycja Open Access Analiza zaburzeń rozwojowych występujących u cieląt urodzonych na terenie działalności Stacji Hodowli i Unasienniania Zwierząt w Kleczy w latach 1976-1990(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Gawlikowski, Jerzy; Bońdos, Edyta; Akademia Rolnicza w Szczecinie, Katedra Anatomii Zwierząt; Akademia Rolnicza w Szczecinie, Katedra Anatomii ZwierzątCase description of 165 calves with developmental abnormalities born in 1976-1990 in the activity area of Animal Breeding and Insemination Station at Klecza is presented, information concerning fathers of calves are given for the most cases. Defects and their distribution are presented in two tables. Among all cases the most numerous was congenital hydrocephaly (hydrocephalus congenitus) found in 24 cases, what stands for 14.55% of all calves described. The largest number of defected calves was fathered by Ygrek 31324-9-6, Mandaryn 04059-9-7, Manhatan 04049-9-3, and Tors 37371-9-3.Pozycja Open Access Mięso kurcząt brojlerów jako źródło magnezu, sodu, potasu, wapnia, fosforu i litu(Wydawnictwo Akademii Rolniczej w Szczecinie, 1997) Gardzielewska, Józefa; Sochacka, Agnieszka; Goluch, Zuzanna; Cyran, Aleksander; Natalczyk-Szymkowska, Wanda; Akademia Rolnicza w Szczecinie, Katedra Oceny Produktów Zwierzęcych; Akademia Rolnicza w Szczecinie, Katedra Oceny Produktów Zwierzęcych; Akademia Rolnicza w Szczecinie, Katedra Oceny Produktów Zwierzęcych; Akademia Rolnicza w Szczecinie, Katedra Chemii Ogólnej; Akademia Rolnicza w Szczecinie, Katedra Oceny Produktów ZwierzęcychThe present study was aimed at determining the content of mineralj: omponents, i.e., Mg, Na, K, Ca, P and Li, in the breast and thigh muscles of 6-week-old cockerels and pullets of the Arbor Acres, Hybro N, Lohmann and Starbro lines. The studies included 96 broiler chickens in total (3 cockerels and 3 pullets out of each line and repetition) in to replicates. The content of these elements was determined in the breast and the thigh muscles separately with the ICP method. In the performed studies, a higher content of Mg, К, P and Li was found in the breast muscles and of Na in the thight muscles. The level of Ca was similar in both types of muscles. The largest amount of Ca was found in meat of chickens of the Lohmann line compared to the remaining linesPozycja Open Access Przypadki wrodzonego braku odbytu u bydła w rejonie działania stacji hodowli i unasienniania zwierząt w Krasnem w latach 1976-1989(Wydawnictwo AkademiI Rolniczej w Szczecinie, 1997) Dobrowolska, Anna; Gawlikowski, Jerzy; Akademia Rolnicza w Szczecinie, Katedra Anatomii Zwierząt; Akademia Rolnicza w Szczecinie, Katedra Anatomii ZwierzątOut of the total number of 1465 newborn calves affected with developmental disorders and recorded on the territory of the Rzeszów Province in 1976-1989, 102 cases were found loaded with congenital atresia ani, what made almost 7% of al cases. In 36 calves atresia ani occurred independently, whereas in 66 cases other additional defects were noted. The most frequent coexisting defects were: anuria, limb arthrogryposes, dyspygia, torticollis, brachyrachia and hypotrichosis. The calves loaded with congenital atresia ani were fathered by 63 bulls. The average length of pregnancy, out of which the calves came, did not differ from its physiological length.
