“…Studies conducted in Brazil determined that the inclusion of ensiled corn kernels in diets can improve the feed efficiency of growing/finishing cattle by an average of 14% as a result of an average 12% feed intake reduction (Berndt et al, 2002;Costa et al, 2002;Putrino, 2006;Henrique et al, 2007;Silva et al, 2007;Almeida Júnior et al, 2008;Carareto, 2011;Caetano et al, 2015;Silva, 2015;Tres, 2015;Silva, 2016). However, these benefits of grain ensiling are based on three major factors (Gomes et al, 2018): moisture content (Owens et al, 1997), particle size (Rémond et al, 2004), and length of storage time (Hoffman et al, 2011).…”

Exogenous fibrolytic enzymes (EFE) improve the energy availability of grains for nonruminant animals by reducing encapsulation of the endosperm nutrients within grain cell walls; however, these benefits are unknown in the treatment of corn-based silage for cattle. The objective of the present study was to evaluate the effects of adding EFE at ensiling on the nutritive value of high-moisture corn (HMC) and snaplage (SNAP) for finishing Nellore bulls. The EFE dose was 100 g/Mg fresh matter in both HMC and SNAP. Diets were 1) a SNAP + HMC control (without enzyme addition); 2) SNAP + HMC EFE (with enzymes); 3) a whole-plant corn silage (WPCS) + HMC control (without enzyme addition); and 4) WPCS + HMC EFE (with enzymes). In addition to the silages, the diets were also composed of soybean hulls, soybean meal, and mineral–vitamin supplement. The statistical design was a randomized complete block with a factorial arrangement of treatments, and the experiment lasted 122 d. For in situ and in vitro analyses, 2 cannulated dry cows were used. There was no interaction between the diets and EFE application (ADG, P = 0.92; DMI, P = 0.77; G:F, P = 0.70), and there was no difference between the SNAP and WPCS diets regarding the DMI (P = 0.53), ADG (P = 0.35), and feed efficiency (ADG:DMI, P = 0.83). Adding EFE to the HMC and SNAP at ensiling did not affect ADG but decreased DMI (P = 0.01), resulting in greater feed efficiency by 5.91% (P = 0.04) than that observed in animals fed diets without the addition of EFE. Addition of EFE to HMC resulted in reduced NDF content and increased in vitro and in situ DM digestibility compared with untreated HMC. No effects were found for the addition of EFE to SNAP. Fecal starch decreased with EFE application (P = 0.05). Therefore, the diet energy content (TDN, NEm, and NEg) calculated from animal performance increased (P = 0.01) with the addition of EFE to HMC. In conclusion, exchanging the NDF from WPCS with that from SNAP did not affect the performance of finishing cattle, whereas the addition of EFE to HMC at ensiling improved animal performance by increasing the energy availability of the grain.

“…A silagem de grãos úmidos inteiros de sorgo apresenta menor custo de produção por dispensar a operação da moagem, assim, seu uso pode trazer vantagens econômicas (Almeida Júnior et al, 2008), podendo ser usado em rações para bezerros holandeses após o desaleitamento, pois não prejudicam o desempenho do animal e conferem os mesmos resultados obtidos com o milho MOUSQUER, C.J. et al Produção de carne de vitelo: sistemas produtivos e aspectos zootécnicos.…”

“…O Brasil não tem tradição na produção de carne de vitelo; inclusive, o termo "vitelo" tem sido desprovido de identidade tanto para produtores quanto consumidores e é genericamente usado para descrever diversos tipos de animais abatidos jovens. Mesmo no Sistema Nacional de Tipificação de Carcaças Bovinas (Portaria 193/84), o vitelo é apenas descrito como o bovino (macho ou fêmea) abatido com até 12 meses (Almeida Júnior et al, 2008).…”

A pecuária brasileira de corte e de leite produz certa proporção de bezerros problemáticos, de baixo valor, aqueles considerados "fundo de boiada" e bezerros machos na produção leiteira, que poderiam ter melhor aproveitamento econômico. A utilização de machos leiteiros é bastante difundida e desenvolvida nos países Europeus, onde estes animais são utilizados para produção de carne e considerados uma importante fonte de renda para os produtores de leite e para a cadeia produtiva da carne. Os bezerros podem ser criados para a produção de vitelos de carne branca ou vitelos de carne rosa. Sendo esses últimos, apresentando maiores perspectivas

“…Given the notable advancements and significant transformations in the dairy industry, milk producers are increasingly recognizing the importance of efficient animal husbandry as a key factor in their operations. This shift towards efficiency not only enhances competitiveness but also empowers them to adopt an entrepreneurial mindset, regardless of the scale of their production system (Lopes et al, 2009). Effective livestock planning and financial management have become essential strategies for overseeing the entire production system with the ultimate goal of generating profit for rural producers.…”

The complete rearing cycle of dairy calves is not yet widely adopted by rural producers, possibly because they do not perceive these animals as potential meat producers or are unaware of their production capabilities. This study aimed to assess the economic viability of rearing dairy calves through their entire growth cycle. Sixteen Holstein × Gyr crossbred animals were assessed, originating from dairy farming, with an average initial weight of 40.67 ± 5.27 kg and slaughtered at 10 months of age, reaching a final weight of 320.4 ± 45.87 kg. These calves were reared in a feedlot system and received a mash diet without the inclusion of roughage. The experiment was conducted on a farm primarily focused on dairy farming, situated in the municipality of Turvânia, GO, Brazil. Economic evaluations were conducted at the conclusion of the production cycle, with the calculation of the value of the arroba (@ = 15 kg) produced. Data were analyzed using a production cost structure methodology, which included effective operating cost, total operating cost, and total cost. The following economic indicators were examined: gross revenue, gross margin, net margin, and the break-even point. Results were highly promising, demonstrating a profit from raising dairy male calves, with a net margin per animal of BRL 321.50. Additionally, these animals displayed noteworthy potential for weight gain and carcass quality. A total of 149.19 @ were produced, averaging 9.32 @ per animal, with a production cost of BRL 105.52, encompassing expenses such as milk consumption, concentrate diet, and labor, which amounted to BRL 1.18 per month per animal. These findings underscore the economic feasibility of this rearing system.
