“…Steers fed SFC had a larger u) < .05) longissimus muscle area than steers fed SFSG, resulting in lower u) < .05) yield grades for SFC steers. This result is in contrast to those obtained in other studies comparing sorghum grain and corn (Maxson et al, 1973;Brethour, 19851, and a biological explanation is not readily apparent.…”

“…Reduction in ADG when replacing corn by HTS was of a magnitude similar to reports in the literature. Maxson et al (1973) reported a 24% reduction in ADG, whereas we observed a 21% reduction in ADG when comparing HTS to the corn-fed group, the same reduction observed by Fox et al (1970).…”

“…Feed efficiency (G:F) was less for HTS than corn (P < 0.01; Table 2), but G:F for steers fed HTS (19.3 g/100 g) was almost twice the efficiency reported in the works of Maxson et al (1973), Brommelsiek et al (1979), and Fox et al (1970). These studies reported G:F of 10.0 g/100 g, 10.5 g/100 g, and 10.1 g/100 g, respectively.…”

The objective of this work was to compare feedlot performance, carcass characteristics, and beef sensory attributes from steers finished with diets based on corn, high-tannin sorghum (HTS), and a mix of both grains. Angus crossbred steers (n = 11 steers per treatment, initial BW = 404 +/- 18 kg) were finished on diets containing 765 g/kg of DM of corn, HTS, or a 1:1 mix of corn and HTS. Final BW (P < 0.01), ADG (P < 0.001), and G:F (P < 0.01) were reduced in steers fed HTS when compared with steers fed corn. Steers fed the mixed diet had greater G:F than the average between corn and HTS diets (P = 0.04), which indicated that mixing corn and HTS had positive associative effects. Estimated NE(m) of HTS was 1.91, and estimated NE(g) was 1.35 Mcal/kg of DM. Hot carcass weight (P < 0.01), trimmed carcass weight (P < 0.01), yield grade (P = 0.04), and 12th-rib fat thickness (P = 0.01) were less in steers fed HTS than in those fed corn. Estimated percentage of HCW as boneless, closely trimmed retail cuts was greater in steers fed HTS compared with those fed corn (P = 0.02) but, due to the decreased HCW, estimated amount of boneless, closely trimmed retail cuts was less in steers fed HTS than in those fed corn (P = 0.03). Steers fed HTS had greater pH on LM (P = 0.02) than steers fed corn, but the difference was small (5.42 +/- 0.02 vs. 5.36 +/- 0.02, respectively) and within the range of normal beef pH. Diet had no effect on Warner-Bratzler shear values (P > or = 0.72). Multivariate ANOVA indicated a difference in sensory attributes of beef from corn and HTS steers (Wilks' Lambda, P = 0.04). When evaluating each sensory attribute independently, panelists found beef from steers fed HTS to be less juicy (P < 0.01), less tender (P = 0.03), and more cooked (P < 0.01) than beef from animals fed corn. Data from this study indicated that by using a 1:1 mix of HTS and corn it is possible to finish steers to similar BW and carcass quality as by using a corn-based diet. Also, total replacement of corn by HTS in the diets produced lighter and leaner animals. Total replacement of corn by HTS in the finishing diet changed beef sensory attributes, reducing the perception of beef tenderness and juiciness by panelists but without changing instrumental tenderness.

“…No presente trabalho não foi observado o efeito depressor dos taninos sobre o consumo de matéria seca. Também, Maxson et al (1973) e Riffel (2002 verificaram maior consumo de matéria seca em ração contendo alto teor de tanino. Provavelmente, houve degradação dos taninos do grão durante o processo de ensilagem, reduzindo a concentração deste fator anti-nutricional, sem acarretar redução do consumo de matéria seca nos animais alimentados com ração de alto teor em tanino (BHATET al., 1998).…”

RESUMO Objetivou-se avaliar três tipos de silagem de grão úmido de sorgo (alto tanino, baixo tanino e branco), na forma de silagem de grão úmido, combinados com duas formas de fornecimento da ração (volumoso e concentrado fornecidos de forma separada ou misturada), sobre o consumo de matéria seca, evolução do peso vivo, ganho de peso médio diário, conversão alimentar e principais características de carcaça (área de olho de lombo, espessura de gordura subcutânea e marmorização in vivo e post mortem) e carne (cor, maciez e pH) de novilhos cruzados Hereford-Angus. Foram utilizados 48 bovinos machos, castrados, cruzados Hereford-Angus, com idade média de 20 meses, divididos em blocos casualizados, em fatorial 3 × 2. A regressão do ganho de peso de cada tratamento foi comparada utilizando-se contrastes ortogonais. Para consumo de matéria seca relativo, houve efeito do tipo de sorgo (P=0,002) e forma de fornecimento da ração (P=0,0005). A forma de fornecimento da ração pode interferir sobre o consumo de matéria seca absoluto e peso vivo médio (P=0,0001). Para a conversão alimentar foi observado efeito do tipo de sorgo (P=0,04. Observou-se efeito da forma de fornecimento da ração para a marmorização (P=0,04) post mortem. Não houve efeito do tipo de sorgo e da forma de fornecimento da ração sobre as características de carcaça e pesos dos cortes cárneos. O fornecimento do volumoso separado do concentrado na alimentação de bovinos confinados é viável do ponto de vista operacional e nutricional.
