Cím:	Growth rate and carcass quality of hybrid fatteners depending on the age of slaughter / Hanna Jankowiak, Aleksandra Cebulska, Gabriella Novotni-Dankó, Péter Balogh, Anna Zmudzińska

Megjegyzések:	The aim of the study was to evaluate the effect of age on the fattening performance qualities and carcasses slaugh- ter value. The assessment covered 99 crossbred pigs (Danish Landrace X Yorkshire X Duroc). The animals were subdivided into two groups with different slaughter age (159 and 169 days). The assessment covered fattening and post-slaughter characteristics. It has been proven that, at slaughter, younger crossbred pigs showed a higher growth rate than older pigs (P < 0.01). In addition, the former were fattened for a shorter period and consumed less feed across the entire fattening period as well as per 1 kg of gain. Carcasses of pigs older at slaughter were characterised by greater warm carcass weight and height of the loin muscle relative to group I carcasses (P < 0.01). Slaughter value of fatteners from both groups studied was very high, as each of the carcasses under assessment was classified under the most valuable categories S, E, and U.

Cím:	Impact of piglet birth weight on later rearing performance / H Jankowiak, P Balogh, A Cebulska, E Vaclavkova, M Bocian, P Reszka

Megjegyzések:	The piglet birth weight and its variance within a litter may be considered important traits that influence pig productivity in the first and later stages of rearing. 222 piglets were evaluated from the moment they were born until weaning, and then as fattening pigs until the end of the fattening (n = 207) in three birth weight groups. Negative consequences of an excessively low piglet birth weight were observed, including higher mortality until weaning and a lower average daily gain during suckling. The correlation coefficients between the piglet birth weight and the remaining indicators confirmed the negative impact of the low piglet birth weight, fattening performance and carcass slaughter value (P < 0.01). The regression analysis between the piglet birth weight and the growth rate during the whole rearing phases indicated that only the piglet growth rate from birth to weaning is determined by their birth weight.
