The Influence of Piglet Birth Weight on Growth Performance
Result description
The aim of the study was to estimate the effect of piglet birth weight on future growth intensity of pigs. Piglets (n=80) were weighted after birth, at age of 21 days, 28 days, 38 days, 4 weeks before slaughter, 2 weeks before slaughter and at the day ofslaughter. For purpose of the study pigs were divided in four groups according their birth weight (less than 1000 g, 1001-1200 g, 1201-1500 g, 1501 g and more) and average daily gain in particular periods was calculated. Low birth weight was associatedwith decreased survival and lower postnatal growth rates. The pigs with low birth weight grew slower than pigs with higher live weight at birth. The lowest daily gains were found in pigs with the lowest birth weight during their growing and finishing period (P<0.01-0.001). They achieved the average daily gain from birth to slaughter of 546.04 ? 35.44 g in comparison to pigs with the heaviest birth weight (732.04 ? 40.19 g). Pigs with birth weight 1201-1500 g reached the slaughter weight
