The purpose of the work was to determine the effect of the fi bre content in the mixture on morphometric traits of intestinal epithelium of fatteners. In one-phase fattening, 14 crossbred pigs were classifi ed into two groups and ad libitum fed the mixtures, differing in the composition and nutritional value, including the level of crude fi bre (control group – C – 3.4%; experimental group – E – 12%)...
The aim of the paper was to evaluate the effect of the birth body weight of the piglets on their productivity and survivability up to the age of 10 weeks. The observations covered the piglets born by 11 sows F1 of Polish Large White × Polish Landrace, inseminated by the semen of the boras (Duroc × Pietrain). The piglets were weighed on 1st, 21st, 35th and 70th day of life and the feed intake (per...
Celem pracy było określenie wpływu terminu (półrocze, kwartał, miesiąc) urodzenia loch na uzyskane przez nie wskaźniki rozrodu, liczbę prosiąt urodzonych (LPU) i liczbę prosiąt odchowanych do wieku 21 dni (LPO). Materiał do badań stanowiły wyniki użytkowości rozpłodowej loch użytkowanych w stadach zarodowych rasy wielka biała polska (1048 rekordów) i polska biała zwisłoucha (1791 rekordów) w latach...
Celem pracy było określenie wpływu liczebności miotu, z którego pochodziły lochy na liczbę prosiąt żywo urodzonych i odchowanych do 21. dnia. Materiał do badań stanowiły dane o użytkowości rozpłodowej samic pbz i wbp (1791 i 1047 rekordów), użytkowanych w latach 2004-2009 w stadach zarodowych mazowieckiego rejonu hodowlanego. Na podstawie liczebności miotu pochodzenia, lochy przydzielono do grup:...
The purpose of the studies was to determine the number of piglets born (NPB) and reared until 21 day (NPR) by the sows of Polish Landrace and Polish Large White breeds, differing in the number of teats. For calculations, the results from breeding pig houses of the Mazovian region, collected during the years 2004-2009, were employed. Three groups of females were distinguished for the particular breeds:...
The aim of the study was to evaluate the effect of the application of a prophylactic program based on effective microorganisms on the run and the results of fattening (daily weight gain) and slaughter value (fat thickness, longissimus muscle depth, meatiness) and state of intestinal microflora (colony-forming unit CFU, coefficient coli/lacto) of fatteners. Together with the feed or with water, Pro-Biotyk...
Badaniami objęto 16 miotów prosiąt (Näima x Neckar), po 8 w grupie kontrolnej (85 prosiąt) i doświadczalnej (87 prosiąt), oraz ich matki. Prosiętom z grupy kontrolnej (K) podano jednorazowo w iniekcji po 1 ml/szt. preparatu Gleptosil, a z grupy doświadczalnej (D) 3-krotnie, w 3., 7. i 11. dniu życia, per os po 40 g/miot preparatu Hemoral. Określone dla siary i mleka loch parametry jakościowe (skład...
An experiment with 94 fattening pigs (48 gilts and 46 barrows) was conducted to determine the effect of feeding 25% restricted diets at different body weights on meat quality and fatty acid profile of M. longissimus thoracis (LT). During the 84days of the experiment (4 periods, 21days each), animals with an initial weight of about 31kg were fed in different periods of observation ad libitum (A) or...
Celem pracy było określenie i porównanie poziomu wybranych wskaźników morfologicznych i biochemicznych krwi 34 loch mieszańców F1 (pbz x wbp), pierwiastek (P) i wieloródek (W), w 104. (±2-3) dniu ciąży (C) i w 21. dniu laktacji (L). Niektóre wskaźniki morfologiczne i biochemiczne różniły się w zależności od fazy cyklu reprodukcyjnego i kolejności oproszenia. Liczba płytek krwi była wysoko istotnie...
The aim of the studies was to determine the relationship between the placenta weight and fatness of the sows in late pregnancy, their body weight and reproduction indices. The evaluation covered 89 F1 sows (PLW x PL) and their progeny. The high-pregnant sows (104 ±2 days) were weighed; fatness of animals (points: P1, P2, P3 and P4) and height of musculus longissimus dorsi (MLD) was determined (P4M)...
A study conducted on 24 fatteners was undertaken to determine the effect of the level of feeding pigs in the first period of fattening on fatty acids profile of their muscles. In animals with body weight (b.w.) of 23 kg, the content of crude fat was similar in all muscles examined. In a lipid fraction of M. longissimus thoracis, M. semimembranosus and heart muscle of pigs with b.w. of 23 kg and 60...
