“…Wet corn gluten feed (WCGF), a co-product of the wet-milling process, is a high-fiber, low-lignin feedstuff that has been repeatedly demonstrated to be a viable option for inclusion into lactating dairy cattle rations (Wickersham et al, 2004;Mullins et al, 2009). Although the fiber in WCGF is highly digestible, its effective NDF content can be variable depending on the method used to estimate it.…”

Productivity of lactating dairy cows fed diets with wet corn gluten feed (WCGF, Sweet Bran, Cargill Inc., Blair, NE) as the primary energy substrate and prairie hay as the primary source of physically effective neutral detergent fiber (peNDF) was assessed relative to a control diet. Forty-eight Holstein cows, 100 to 250 d in milk, were randomly assigned to 1 of 6 pens and pens were randomly assigned to treatment sequence in a replicated 3×3 Latin square. Treatments were a control diet with 18% alfalfa, 18% corn silage, 33% WCGF, and 15% forage NDF (CON); a diet with 20% tallgrass prairie hay, 46% WCGF, and 13% forage NDF (TPH20); and a diet with 14% tallgrass prairie hay, 56% WCGF, and 9% forage NDF (TPH14). Midway through period 2, TPH14 was discontinued due to the high prevalence of diarrhea among cows on that treatment. Data from period 2 for TPH14 pens were discarded, and the pens that had been assigned to TPH14 for period 3 were randomly assigned to the other 2 treatments. Pen-level data were analyzed using linear mixed models, including the random effects of period and pen and the fixed effect of treatment. For animal-level data, additional random effects were introduced to account for subsampling. No evidence for treatment effects was apparent on dry matter intake. Least squares mean milk yields were 36.2, 34.6, and 35.2 kg/d for CON, TPH20, and TPH14, respectively, and were not significantly different. Milk fat concentration was higher for CON and TPH20 than for TPH14, with means of 3.48, 3.41, and 2.82%, respectively. Fat yield was significantly greater for CON compared with TPH20 and TPH14. Milk urea nitrogen was greatest for TPH20 and TPH14 and least for CON, consistent with differences in dietary protein content. Efficiencies, expressed as energy-corrected milk divided by dry matter intake, were 1.47, 1.42, and 1.24 for CON, TPH20, and TPH14, respectively, and were not significantly different. These data indicate that TPH14 did not provide adequate peNDF to support normal rumen function in mid lactation dairy cows; instead, TPH20 may be a feasible diet for use on dairies where high-NDF grass hay and WCGF are available.

“…Corn gluten feed also contains approximately 35% NDF and low levels of lignin (2%), and is a source of highly digestible fiber that may supply energy to the lactating dairy cow. Because WCGF contains a relatively low concentration of rapidly fermentable carbohydrates such as starch, these feeds supply energy without increasing the risk of ruminal acidosis (Wickersham et al, 2004).…”

An experiment was conducted with 36 primiparous and 40 multiparous Holstein cows to examine the effects of feeding wet corn gluten feed (WCGF) on 305-d milk production, dry matter (DM) intake, body condition score (BCS), and health. The experimental treatments included: 1) control-WCGF not fed (n = 27); 2) WCGF-L-cows received diets containing WCGF (38% DM basis) during lactation (n = 23); and 3) WCGF-DL-cows received diets containing WCGF (38% DM basis) during the dry period and lactation (n = 26). During the dry period, cows consuming WCGF were observed to have a significant gain in BCS (0.07 ± 0.06) compared with a loss in BCS in cows fed the control diet (control = −0.11 ± 0.06 and WCGF-L = −0.04 ± 0.06). During lactation, there were no differences by treatment on BCS. Cows consuming WCGF during lactation consumed more feed compared with the control: 25.4, 23.8, and 21.2 ± 0.76 kg/d for WCGF-L, WCGF-DL, and the control, respectively. Milk production was higher for cows consuming WCGF: 35.0, 34.7, and 31.1 ± 2.1 kg/d for WCGF-L, WCGF-DL, and the control, respectively. No differences were found in either DM intake or actual milk yield between the WCGF-L and WCGF-DL treatments, indicating that prepartum diets did not influence lactational performance. The WCGF diets resulted in significant reductions in the concentration of milk fat (3.94, 3.74, and 4.15 ± 0.08% for WCGF-L, WCGF-DL, and the control, respectively), but because total milk yield was increased, there were no differences in total milk fat yield. In addition, 3.5% of fat-corrected milk tended to be affected by diet: 38.9, 36.3, and 34.7 ± 1.93 kg/d for 2608WCGF-L, WCGF-DL, and the control, respectively. The increasing effect of DM intake and milk yield in cows consuming WCGF resulted in a similar efficiency of 3.5% fat-corrected milk production for all treatments, averaging 1.5 ± 0.09. Total protein yields were significantly higher for cows consuming WCGF diets during lactation: 1.15, 1.10, 1.00 ± 0.06 kg/d for WCGF-L, WCGF-DL, and the control, respectively. These results indicate that diets may be formulated to contain as much as 37.5% WCGF (DM basis).

No nível mais baixo, 21,9% da MS, não houve diferenças no teor de proteína do leite.…”

“…Da mesma forma que para a proteína do leite, na maioria dos trabalhos revisados, não se observou alteração nos teores de lactose do leite (Blasi et al, 2001;Vanbaale et al, 2001;Schroeder, 2003;Alves et al, 2005;Kononoff et al, 2006). De maneira contrária, Wickersham et al, (2004) verificaram aumento no teor de lactose do leite com a inclusão do FGM-21 em substituição a parte do concentrado e parte do volumoso. A redução no teor de lactose observada nesta pesquisa pode estar relacionada à menor disponibilidade energética proporcionada pelas rações com o subproduto, o que reduziria o aporte de glicose para a glândula mamária, prejudicando a síntese de lactose.…”

RESUMO -Avaliou-se a substituição do milho moído por farelo de glúten de milho (FGM-21) para vacas em lactação alimentadas com ração completa contendo silagem de milho como volumoso principal e polpa cítrica como parte da fonte energética. Trinta vacas holandesas no terço médio de lactação foram mantidas em delineamento quadrado latino 3 × 3, composto de 10 quadrados simultâneos, e alimentadas com três rações completas: sem FGM-21 e com 20% de milho na matéria seca (MS); 10% de FGM-21 e 10% de milho moído na MS; e 20% de FGM-21 na MS e sem milho moído. As variáveis analisadas foram: consumo de matéria seca, produção e composição do leite, concentração de nitrogênio ureico no leite, parâmetros sanguíneos e escore de condição corporal das vacas. Os animais foram dispostos em 10 quadrados latinos 3 × 3, de acordo com a produção de leite, os dias em lactação e a paridade. A ingestão de MS (21,19 kg/dia), a produção de leite (24,88 kg/dia), a produção de leite corrigida para 3,5% de gordura (25,34 kg/dia), o teor de gordura (3,62%) e o teor de sólidos totais (11,86%) não foram afetados pela substituição do milho moído por farelo de glúten de milho. A inclusão do farelo de glúten de milho afetou os teores de proteína e lactose do leite e a concentração de nitrogênio ureico do leite.Palavras-chave: produção e composição do leite, resíduos fibrosos, ruminantes, subprodutos, vacas em lactação Replacing corn grain with corn gluten feed in the diet of feedlot lactating cowsABSTRACT -Thirty mid lactating Holstein cows (159 DIM) were used to evaluate the substitution of ground corn with gluten feed (FGM-21) in total mixed diets containing corn silage as the main forage and citrus pulp as part of the energy source. Treatments were: no FGM-21 and 20% ground corn in total feed DM (FGM 0), 10% FGM-21 and 10% ground corn in total feed DM (FGM 10), and no corn and 20% FGM-21 in total feed DM (FGM 20). The parameters evaluated were: dry matter intake, milk yield and composition, milk urea N concentration, blood parameters and body condition score. Cows were randomly assigned in ten 3 × 3 Latin Squares, according to milk yield, days in lactation and parity. Treatments did not affect the daily dry matter intake (DMI) (21.19 kg/d), milk yield (24.88 kg/d), FCM yield (25.34 kg/d), milk fat content (3.62%), and milk total solids (11.86%). Inclusion of corn gluten feed affected milk protein, lactose and urea concentrations.Key Words: byproducts, fibrous feeds, lactating cows, milk production and composition, ruminants IntroduçãoA crescente demanda pela utilização racional e sustentável dos recursos alimentícios em todo o mundo tem exercido pressão cada vez maior sobre a necessidade de se pesquisar a utilização de fontes alimentícias alternativas na nutrição animal que não causem competição por alimentos usados em larga escala na alimentação humana. Nesse contexto, a busca por alternativas para substituir os grãos de cereais na alimentação de ruminantes assume grande importância.Além disso, o custo dessas fontes tradicionais de alimento t...
