    The aim of study was to determine of basic values slaughter meat production and histological parameters of pectoral muscle in quadruple 24 weeks old crossbred geese. The hybrids produced using Graylag, White Kołuda and Slovakian geese. The geese were divided to 4 groups differing crosses scheme. The body weight before slaughter was in the range from 4,752 g to 4,921 g, weight of carcass with neck from 3,101 g to 3,175 g and weight of breast muscles from 649 g to 698 g. Histological analysis of pectoral muscle showed that diameters of white fibers (αW) was in the range from 43 μm to 46 μm, red fibers (βR) from 19.4 μm to 22.1 μm. The percentage share of αW muscle fibers was in the range from 25.3% to 28.9%, βR fibers from 71.1% to 74.7%. The number of muscle fibers per unit area was in the range from 256 to 316 and intramuscular fat content from 3.9% to 6.7%. The results of evaluation of microstructural traits of musculus pectoralis superficialis and meat production parameters suggest that the breast muscles of the crossbred geese are raw material of high quality. The quadruple crossbred geese with graylag geese it is an alternative for production of high-quality meat.Celem pracy było określenie podstawowych wskaźników użytkowości mięsnej i cech histologicznych mięśnia piersiowego 24-tygodniowych poczwórnych mieszańców gęsi. Mieszańce pochodziły z krzyżowania dzikiej gęsi gęgawej, Białej Kołudzkiej i Słowackiej. Gęsi przydzielono do 4 grup różniących się systemem krzyżowania. Masa ciała ptaków przed ubojem mieściła się w graniacach od 4 752 g do 4 921 g, masa tuszki patroszonej z szyją od 3 101 g do 3 175 g i masa mięśni piersiowych od 649 g do 698 g. Ocena histologiczna mięśnia piersiowego wykazała, że średnica włókien białych (αW) wynosiła od 43 μm do 46 μm, włókien czerwonych (βR) od 19,4 μm do 22,1 μm. Procentowy udział włókien αW mieścił się w granicach od 25,3% do 28,9%, βR od 71,1% do 74,7%. Ilość włókien na jednostce powierzchni mieściła się w granicach od 256 do 316, a udział tłuszczu śródmięśniowego wynosił od 3,9% do 6,7%. Wyniki oceny cech mikrostruktury musculus pectoralis superficialis i cech użytkowości mięsnej sugerują, że mięśnie piersiowe gęsi mieszańców są wysokiej jakości surowcem rzeźnym. Poczwórne mieszańce wytworzone z udziałem dzikiej gęsi gęgawy stanowią alternatywę w produkcji mięsa o wysokiej jakości

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
