Dirunal variations in rabbits: hematological parameters

Hematological parameters in Polish mixed breed rabbits with addition of meat breed blood in the annual cycle

“…Haematological parameters in mix-breed Polish rabbits with addition of blood of meat breed blood in annual cycle considering sex. Legend: ( ) -number of animals; x -mean value; SD -standard deviation, a -statistically significant difference between male and female, b -statistically significant difference between seasons (together), where b1 -statistically significant difference between spring and summer; b2 -statistically significant difference between spring and autumn; b3 -statistically significant difference between spring and winter; b4 -statistically significant difference between summer and autumn; b5 -statistically significant difference summer and winter; b6 -statistically significant difference between autumn and winter in the present study (Pintor and Grassini 1957, Fox and Laird 1970, Bortolotti et al 1989, Kabata et al 1991, Aleman et al 2000, Cazabon et al 2000, Rohilla et al 2000, Kim et al 2002, Burnett et al 2006, Chineke et al 2006, Olayemi and Nottidge 2007, Archetti et al 2008, Black et al 2009, Ç etin et al 2009, Jeklova et al 2009, Poljičak-Milas et al 2009, Abdel-Azeem et al 2010, Martinec et al 2012, Ö zkan et al 2012, Yaqub et al 2013). …”

“…In turn, the results of the studies obtained presently, as compared to the results obtained abroad, are different and difficult to compare with prior results (Fox and Laird 1970, Kabata et al 1991, Aleman et al 2000, Kim et al 2002, Burnett et al 2006, Chineke et al 2006, Black et al 2009, Ç etin et al 2009, Poljičak-Milas et al 2009, Abdel-Azeem et al 2010, Ö zkan et al 2012, Yaqub et al 2013). The present study does not confirm the results obtained by Kabata et al 1991 (Fox and Laird 1970, Aleman et al 2000, Kim et al 2002, Chineke et al 2006, Black et al 2009, Abdel-Azeem et al 2010, despite the assessment of the impact of sex on the behaviour of red and white blood cell image parameters in rabbits, did not show any significant changes in this respect. To conclude on the impact of the sex of Polish mixed-breed rabbits with addition of blood of meat breeds on haematological parameters of blood, it is hard to make absolute statements on the impact of this factor on the parameters analysed, as similarly to the case of the first group of rabbits (Polish mixed-breed rabbits) the results are very differentiated.…”

“…On the other hand, the worldwide research have been performed on rabbits of different races (New Zealand, Agora, Czech and Sylvilagus Bachmani Riparius, cottontail, Soviet Chinchilla, grey giant, albino) and many unspecified mixed-breed rabbits, but only some of them have analysed the impact of the season of the year (Pintor and Grassini 1957, Black et al 2009, Ç etin et al 2009, Abdel-Azeem et al 2010, Yaqub et al 2013, sex (Fox and Laird 1970, Kabata et al 1991, Aleman et al 2000, Kim et al 2002, Burnett et al 2006, Chineke et al 2006, Black et al 2009, Ç etin et al 2009, Poljičak-Milas et al 2009, Abdel-Azeem et al 2010, Ö zkan et al 2012, Yaqub et al 2013, age (Bortolotti et al 1989, Chineke et al 2006, Olayemi and Nottidge 2007, Archetti et al 2008, Jeklova et al 2009, Yaqub et al 2013, and race of rabbits (Cazabon et al 2000, Rohilla et al 2000, Burnett et al 2006, Chineke et al 2006, Martinec et al 2012, Yaqub et al 2013. Also books (Feldman et al 2000, Harkness et al 2007 regarding reference values for haematological parameters in rabbits, present such values only for the New Zealand race, and do not account for environmental or physiological factors.…”

Natural immunity factors in Polish mixed breed rabbits

“…Furthermore, when assessing such parameters in rabbits, the impact of the season of the year and sex of the animals have not been analysed, and the importance of such factors has been Correspondence to: P. Niedźwiedzka-Rystwej, email: paulina.niedzwiedzka@gmail.com, tel. : +48 91 444 16 05 evidenced in reference to haematological factors (Pintor and Grassini 1957, Fox and Laird 1970, Nowaczyk et al 2005, Burnett et al 2006, Chineke et al 2006, Black et al 2009, Cetin et al 2009, Poljičak-Milas et al 2009, Abdel-Azeem et al 2010, Ö zkan et al 2012, Yaqub et al 2013), although Nowaczyk et al (2005) recorded, in Polish mixed-breed rabbits, the influence of the year season on the polimorphonuclear (PMN) cells adherence capacity and lysozyme (LZM) volume in serum. It must be mentioned that natural immunity factors are so important that their role has been evidenced in bacterial and viral infections in rabbits (Tew et al 1971, Tokarz-Deptułasubstances, including drugs (Prokopowicz 1972, Prokopowicz and Ziobro 1972, Szmigielski 1972, Rausch and Moore 1975, Garbuliński et al, 1985, Dębowy et al 1988, Obmińska-Domoradzka 1992, Świtała 1992, Obmińska-Domoradzka et al 1993, Wessely-Szponder et al 2012.…”

B-cell and T-cell values in peripheral blood in Polish mixed-breed rabbits with addition of blood of meet breeds

“…: +48 91 444 1605 in peripheral blood have only been carried out in Poland on typical Polish mixed-breed rabbits (Table 1), while analogical foreign studies were performed on New Zealand and Fauve de Bourgogne rabbits, as well as LP and V genetic lines, and on Spanish mixed-breed rabbits (Table 2). Despite the fact that the studies were performed on a limited material, they are not determining reference values, and they were not assessed in the context of physiological and environmental conditions, which importance in rabbits was evidenced in the previous studies on haematologi- Legend: ns -not studied; x -mean value, SD ± -standard deviation cal factors (Pinna Pintor and Grassini 1957, Fox and Baird 1970, Laird et al 1970, Bortolotti et al 1989, Jain 1994, Rohilla et al 2000, Nowaczyk et al 2004, Nowaczyk et al 2005, Burnet et al 2006, Chineke et al 2006, Olayemi et al 2007, Archetti et al 2008, Black et al 2009, C etin et al 2009, Jeklova et al 2009, Poljičak-Milas et al 2009, Abdel-Azeem et al 2010, Martinec et al 2012, Ö zkan et al 2012, Yaqub et al 2013). The observations carried out in Poland on typical Polish mixed-breed rabbits showed the impact of animal age (Deptuła et al 1995) and season of the year (Nowaczyk et al 2004(Nowaczyk et al , 2005, while foreign studies performed on New Zealand, Angora, Czech rabbits and Sylvilagus Bachmani Riparius breeds, as well as mixed-breed rabbits, not only evidenced the impact of the age (Laird et al 1970, Bortolotti et al 1989, Chineke et al 2006, Olayemi and Nottidge 2007, Archetti et al 2008, Jeklova et al 2009…”
