TOFOLI, C.A. et al. Nutritional evaluation of high moisture corn silage with different oil contents for piglets in nursery phase. Arq. Bras. Med. Vet. Zootec. [online]. 2006, vol.58, n.6, pp. 1206-1213. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352006000600033.
Sixty crossbred weaned pigs (Large White x Landrace) average initial body weight of 7.9kg and 20 crossbred pigs average initial body weight of 16.8kg were used in the performance and digestibility experiments, respectively, to evaluate high-moisture corn silage with different oil contents. The nutritional value of high-moisture corn silage and dry corn with normal (4.3% EE in DM) or higher (5.66% EE in DM) oil contents were analyzed. The treatments had no effect on either average daily feed intake (ADFI) or average daily gain (ADG) from 0 to 9 and 0 to 31 days. The piglets had higher feed/weight gain in both periods when fed silage and in the period from 0 to 9 days when fed higher oil content corn. In the digestibility experiment only the digestible and metabolizable fractions of energy were affected by the processing method and the silage provided higher energy utilization regardless of the oil content in the grains.
