“…Nevertheless, recent studies have indicated that when fermentation is controlled, the use of sugarcane in well-balanced diets provides satisfactory results in animal production (Pedroso et al, 2006;Queiroz et al, 2008;Mendes et al, 2008).…”

-The objective of the present study was to evaluate the performance of beef cattle in feedlots fed diets containing either whole-crop maize silage or sugarcane silage, and with different formulations. Five diets were evaluated:MSF -diet containing whole-crop maize silage, with fixed formulation during feedlot period; MSV-diet containing wholecrop maize silage, with variable formulation according to feedlot phase; SCSF -diet containing sugarcane silage with fixed formulation; SCSV-diet containing sugarcane silage, with variable formulation; SCSV/MSV-SCSV diet in initial half of fedlot and MSV diet in final half of feedlot period, respectively. It was used a complete random experimental design, with five treatments and three replicates (pens). It was used 285 steers at 36 months of age, with an initial body weight of 362.4 kg. Diets with whole-crop maize silage promoted greater intake of dry matter (10.5 kg and 2.4% BW) compared with diets containing sugarcane silage (10.1 kg and 2.3% BW). There was no effect of the silages on average daily gain (1.348 kg/animal/day) and live weight at slaughter (481.2 kg BW). SCSV/MSV diet promoted the worst feed conversion (8.0 kg DM/kg BW). Animals fed diets composed of whole-crop maize silage presented greater weight of hot carcass, of carcass yield and subcutaneous fat thickness (262.1 kg, 54.1% and 6.2 mm) compared with the animals fed sugarcane silage (252.5 kg, 52.7% and 4.8 mm).The use of sugarcane silage in diets for finishing beef cattle is feasible and the adjustment of formulation during confinement period does not influence performance of the animals. Replacement of sugarcane silage by whole-crop maize silage during the feeding period affects negatively feed conversion.

“…Assim, diferentes níveis de inclusão de forragens na ração podem resultar em variações no desempenho animal (Queiroz et al, 2008). Entretanto, desde que os parâmetros nutritivos (PB, energia e FDN) sejam ajustados para serem semelhantes ou muito próximos, como no presente estudo, espera-se que não haja diferenças no CMS e no ganho de peso, independente da fonte de forragem.…”

RESUMO.As forragens cumprem um papel essencial no desempenho de bovinos de corte em confinamento. Vinte e quatro machos não castrados Red Norte × Nelore com peso corporal (PC) inicial médio de 439,8 kg e 21,7 meses de idade foram distribuídos em três grupos experimentas e alojados em baias individuais (doze animais) ou coletivas (doze animais em três baias) na Fazenda-Escola do IF Goiano (Campus Iporá). O experimento teve duração de 84 dias (14 dias para adaptação e 70 dias para coleta de dados). Alimentaram-se os animais uma vez ao dia com dietas à base de cana-de-açúcar in natura (Ci), silagem de cana (SC) ou silagem de milho (SM) como fontes de forragem. Avaliouse o consumo de matéria seca (CMS) diariamente pela diferença entre a quantidade oferecida menos a recusada, e registrou-se o PC dos animais a cada 14 dias após jejum de sólidos de doze horas. Não houve efeito (P>0,05) da fonte de forragem sobre o CMS nos animais alojados nas baias individuais, assim como não houve resposta (P>0,05) da fonte de forragem sobre o desempenho corporal. As fontes de forragem não alteraram (P>0,05) as características da carcaça. Os animais alojados nas baias individuais aumentaram (P < 0,05) o peso do trato gastrintestinal vazio (11,9 kg), comparados aos animais alojados nas baias coletivas (10,2 kg). Concluiu-se que as três fontes de forragem (Ci, SC e SM) podem ser recomendadas na alimentação de bovinos de corte em confinamento.Palavras chave: cana-de-açúcar, consumo, peso corporal, Red Norte, silagem de milho Performance of beef cattle fed different forages and housed in individual or collective pensABSTRACT. Forages play a key role on the performance of beef cattle in feedlot systems. Twenty-four non-castrated Red Norte × Nelore males with an average initial body weight (BW) of 439.8 kg and 21.7 months of age were distributed in three experimental groups, and housed either in individual or collective pens (twelve animals in individual pens and twelve in three collective pens) at the School-Farm of IF Goiano (Iporá Campus). The experiment lasted 84 days (14 days for adaptation and 70 days for data collection). Animals were fed once daily with diets containing in natura sugar cane (ISC), sugar cane silage (SCS) or corn silage (CS) as sources of forage. Feed refusals were measured daily and dry matter intake (DMI) was determined by difference. BW was recorded every two weeks after a twelve-hour fasting period. There was no effect (P>0.05) of source of forage on DMI in animals housed in individual pens, as well as there was no response (P>0.05) of source of forage on growth performance. The three sources of forage did not alter (P>0.05)

“…According to Nússio and Scmidt (2005), an earlier study, reducing alcohol accumulation improves animal performance due to an increase in DMI, as a result of improved palatability to bovine. Therefore, the silage of sugarcane may result in a better animal performance when the fermentation is controlled (Queiroz et al, 2008).…”

The aim of this study was to evaluate the performance of crossbred Holstein × Zebu steers fed on the diets containing sugarcane in natura or ensiled with two levels of concentrate (30% and 70%). A total of 32 males of 394 kg of body weight were used in a completely randomized experimental design with four treatments and seven repetitions. The animals reported a high dry matter intake (DMI) (P < 0.05) when fed on the high concentrate levels. The increase in concentrate levels resulted in an approximately 25% to 60% higher DMI as compared to the lowest level offered by silage-based diets and sugarcane in natura. The highest apparent digestibility coefficients of dry matter were observed in the diets based on sugarcane in natura (P < 0.05). The sugarcane based diets also affected (P > 0.05) the digestibility of organic matter, neutral detergent fiber, crude protein, ether extract, and non-fiber carbohydrates. There were no differences (P > 0.05) between the diets for average daily weight gain, carcass dressing, carcass gain, and feed conversion. The diets based on sugarcane in nature or ensiled with 30% and 70% concentrates do not influence the performance of crossbred Holstein × Zebu cattle.
