Abstract: Quantificaram-se o consumo voluntário e a digestibilidade aparente da matéria seca, proteína bruta, energia bruta e balanço de nitrogênio das silagens de cinco genótipos de milho (HT01, HT47C, HT129, AG 5011 e BR 3123). Foram utilizados 15 carneiros alojados em gaiolas metabólicas para coleta total de fezes e urina. O delineamento experimental foi o inteiramente ao acaso com cinco tratamentos e seis repetições. Não foram observadas diferenças entre os genótipos quanto ao consumo e digestibilidade da MS, da EB … Show more

“…Gross energy intake, in kcal/kg 0.75 /day, was similar to the ones presented by Freitas et al (2003) and Ribas et al (2007) Metabolizable energy intakes ranged from 1.510.5 to 2.650.8 kcal/day and were higher than the ones recommended by the NRC (2007), whose requirements are around 590 kcal/day for lambs with 20 kg of BW and daily gains of 100 g. Super early BRS Assum Preto variety presented values for digestible energy intake and metabolizable per kg 0.75 /day higher than Gurutuba and BRS Caatingueiro. This probably happened because that material presented high gross energy contents in association with high apparent digestibility from the gross energy.…”

“…Apparent gross energy results from the present study were similar to those obtained by Ribas et al (2007) (66.6%), who evaluated apparent digestibility from four corn hybrids in lambs. Yet results from this experiment were higher than the ones described by Freitas et al (2003) Regarding energy balance from the searched silages, differences were observed (P<0.05) over all variables, except for gross energy voluntary intake (P>0.05) ( Table 6). …”

“…Freitas et al (2003) also observed no effect of silages of five corn genotypes on DM intake and digestibility. According to Muck and Pitt (1993), both silages had good quality due to their adequate percentage of N-NH 3 /Total N and pH values.…”
