“…These behaviors could explain why average ruminai pH was not different in animals fed these diets, because both diets promote mastication and the corresponding salivation and buffering action. This result would confirm that in forage-free diets, the effectiveness of NDF from WCS is also equivalent to that of BS, as was stated by Clark and Armentano (1993) when WCS was compared with alfalfa haylage in lactating dairy cows fed a diet with a 30:70 forage to concentrate ratio.…”

Eight Simmental heifers (initial BW 313.4 ± 13.2 kg) were randomly assigned to 1 of 4 experimental treatments in a 4 × 4 double Latin square design. The experiment was performed in four 28-d periods. Treatments tested were a control diet in which barley straw (BS) was used as a fiber source and 3 diets where the main difference was the nonforage fiber source used: soybean hulls (SH), beet pulp (BP) in pellets, and whole cottonseed (WCS). All ingredients, except the fiber sources, were ground through a 3-mm screen. Fiber ingredients were incorporated at 10, 17, 17, and 16% (on DM basis) in BS, SH, BP, and WCS, respectively. All diets were offered ad libitum as total mixed ration and designed to be isoenergetic (2.95 Mcal ME/kg DM), isonitrogenous (15% CP, DM basis), and with a NDF content of 20% (on DM basis) although there was a discrepancy between the theoretical and the actual chemical composition of the diets. Particle size separation was performed using the 3-screen Penn State Particle Separator. Animals were allotted in 8 individual roofed concrete pens equipped with a feedbunk and water trough. Intake was recorded over 7 d in the last week of each experimental period. Behavior was recorded for 24-h on d 2 and d 6 of each experimental week using a digital video recording device. A digital color camera was set up in front of each pen. Data recorded, except behavioral activities, were statistically analyzed using the MIXED procedure of SAS. To test treatment effect for each behavioral activity, analysis was performed using the GLIMMIX procedure of SAS. Diets ranked from greater to lesser proportion of particles of less than 1.18 mm as follows: SH, BS, WCS, and BP. Dry matter intake of heifers fed WCS was greater than the remaining treatments (P = 0.049). The greatest average ruminal pH was registered in heifers fed BS (6.4) and BP (6.3) whereas the smallest was recorded in SH diet (5.9), with WCS (6.2) occupying an intermediate position (P = 0.006). Total chewing time was greater (P = 0.001) in BS and WCS than in SH and BP. In conclusion, the nonforage fiber sources tested in this experiment can be used in forage-free diets fed to beef heifers as total mixed ration (TMR) without negative consequences in DMI in SH and BP diets and with an increased DMI in WCS diet. The WCS diet promoted rumination and total chewing time to the same degree as BS, which demonstrates that it is equally effective as this forage fiber source.

“…Whole cottonseed is a nonforage fiber source used most commonly in Brazil as a source of protein and fat but also can be used to replace roughage. Clark and Armentano (1993) compared WLC to alfalfa haylage with mean particle length of 7.6 mm and determined that effective NDF content of the WLC was 1.3 times that of the haylage. Mooney and Allen (1997) estimated physical effectiveness of NDF in WLC to be 50 and 127% that of alfalfa silage cut long (11.4 mm) or short (5.8 mm), respectively.…”

This study was conducted to evaluate the effects of flint corn processing method (CPM) and level of NDF from roughage (rNDF) on performance, carcass characteristics, and starch utilization by finishing Nellore-based cattle fed high-concentrate, flint corn-based diets. In this study, 112 Nellore type bulls (initial BW 384.07 ± 29.53 kg and 24-36 mo of age) were individually fed using Calan gates or individual pens. The animals were used in a randomized complete block design in a 2 × 4 factorial arrangement with 2 CPM, high-moisture flint corn (HMC) or finely ground dry flint corn (FGC), with 1 of 4 levels of rNDF, 3, 8, 13, and 18% (DM basis), using sugarcane silage (SS) as roughage. Bulls were adapted to the finishing diet over a 21-d period and fed for a total of 81 d. Fecal starch (FS) concentration was determined on d 46 and 74 of the feeding period. There was a quadratic effect of rNDF on final BW (P < 0.01) and ADG (P = 0.01). Optimal concentrations of rNDF were estimated using the first derivative of second order polynomials, indicating that final BW and ADG were maximized with 13.3 and 13.0% rNDF, respectively. An interaction was observed between CPM and rNDF (P = 0.05) for DMI, with peak DMI occurring at 11.3 and 13.7% rNDF with FGC and HMC, respectively. Cattle fed HMC had 13.9% greater G:F (P < 0.01) compared with those fed FGC (0.172 vs. 0.151, respectively). There were quadratic effects of rNDF on HCW (P = 0.04) and ME intake (P < 0.01); heaviest carcass weights were estimated, in both cases, to be achieved with 12.8% rNDF. A quadratic effect of rNDF for renal, pelvic, and inguinal fat weight (P = 0.04) was observed, with a peak estimated to occur at 12.6% rNDF. An interaction between CPM and rNDF also was observed for FS (P < 0.05). Bulls fed FGC with 3% rNDF had greater FS content, and FS linearly decreased as concentration of rNDF increased. For bulls fed HMC, FS was 3.0% of DM and was unaffected by rNDF in the diet. Lower FS from bulls fed HMC suggests that availability of starch from flint corn was greater than that of FGC. For Nellore-based cattle fed a flint corn-based diet containing SS and 8% whole lint cottonseed, performance was optimized with 12.8% rNDF. In the absence of cottonseed addition to diets, optimal performance would be expected with about 14.5% rNDF.

“…Além disso, segundo Clark & Armentano (1993), a efetividade da FDN do línter do caroço de algodão é equivalente à efetividade do feno de alfafa, podendo-se inferir que é fonte de fibra adequada para manter a porcentagem da gordura do leite. Um outro ponto favorável à sua utilização é a relativa disponibilidade e custo na região.…”

Este trabalho teve como objetivo avaliar o efeito da inclusão do caroço de algodão em dietas à base de palma forrageira (Opuntia ficus indica Mill.), sobre o desempenho de vacas da raça Holandesa em lactação. O experimento foi feito com cinco vacas, com média de 50 dias de lactação, distribuídas em quadrado latino 5x5. Os tratamentos experimentais foram constituídos da inclusão de caroço de algodão em 0, 6,25, 12,50, 18,75 e 25% da matéria seca da dieta. O caroço de algodão aumentou o consumo de matéria seca, extrato etéreo, nutrientes digestíveis totais, cálcio e fósforo; porém não afetou o consumo de proteína bruta e fibra em detergente neutro. O caroço de algodão aumentou a produção de leite corrigido para 3,5% de gordura (de 26,53 para 31,68 kg por dia), e a produção de gordura do leite (de 0,86 para 1,09 kg por dia); não afetou, porém, a produção de leite sem correção (31,19 kg por dia), a porcentagem de gordura do leite (3,18%) e a eficiência alimentar (1,31 kg de leite corrigido por quilograma de matéria seca consumida). O caroço de algodão melhorou o desempenho animal, quando incluído em até 25% da matéria seca em dietas à base de palma forrageira.
