Digestibility and rumen fermentation of a high forage diet pre-treated with a mixture of cellulase and xylanase enzymes

  • 2021
  • Issue: 3
  • Volume: 51
K. Selzer, A. Hassen, A.M. Akanmu & A.Z.M. Salem Page: 399 - 406

Forages play an important role in ruminant animal production worldwide. Unlocking the nutritional potential of poor-quality tropical forages with fibrolytic enzymes would improve forage digestibility and utilization. Using in vitro and in vivo methods this study investigated the effect of…

Effects of garlic supplementation on in vitro nutrient digestibility, rumen fermentation, and gas production

  • 2021
  • Issue: 2
  • Volume: 51
M.R. Kekana, D. Luseba & M.C. Muyu Page: 271 - 279

Garlic contains secondary metabolites with antimicrobial properties that can alter nutrient digestibility and rumen fermentation, similar to other antimicrobial products. The objectives of the study were to evaluate the effects of garlic powder and garlic juice on in vitro nutrient…

Effects of whey, molasses and exogenous enzymes on the ensiling characteristics, nutrient composition and aerobic stability of maize cobs

  • 2016
  • Issue: 2
  • Volume: 46
A.T. Kanengoni, B.D. Nkosi, M. Chimonyo, B. Ndimba & K. Dzama Page: 113 - 120

The study was conducted to assess the effects of whey, molasses and exogenous enzymes on fermentation, aerobic stability and nutrient composition of ensiled maize cobs. Five treatments were ensiled in 1.5 L anaerobic glass jars over 32 days, namely i)…

Effects of supplementing humates on rumen fermentation in Holstein steers

  • 2011
  • Issue: 2
  • Volume: 41
C.P. McMurphy, G.C. Duff, S.R. Sanders, S.P. Cuneo & N.K. Chirase Page: 134 - 140

Humates have nitrogen-binding qualities that could prove to be beneficial in the retention of ammonia nitrogen in the rumen of Holstein steers fed a high-concentrate finishing diet. Therefore, four ruminally fistulated Holstein steers were used in a 4 x 4…

Influence of supplemental aminooligosaccharides on in vitro disappearance of diets for dairy cattle and its effects on milk yiel

  • 2010
  • Issue: 4
  • Volume: 40
J.A. Sánchez, J.M. Pinos-Rodríguez, S.S. González, J.R. Barcena and J.C. García Page: 294 - 300

Two experiments were conducted to evaluate the influence of supplemental aminooligosaccharides (AOS) on the disappearance and fermentation of diets for lactating cows, and its effects on milk yield and quality. In the first study, diets containing 0 or 0.2% AOS…

Adaptation effects of ionophores on rumen fermentation

  • 1983
  • Issue: 1
  • Volume: 13
A. de Jong & F. Berschauer Page: 67 - 70

The effect of monensin on the in vitro degradation of cellulose was investigated using ruminal fluid obtained from sheep adapted and unadapted to the antibiotic. In vivo ruminal adaptation to monensin was also examined over a six-week treatment period. Results…

Fermentative digestion in the ostrich (Struthio camelus var. domesticus), a large avian species that utilizes cellulose

  • 1993
  • Issue: 5
  • Volume: 23
D. Swart, R.I. Mackie and J.P. Hayes Page: 127 - 135

The production of volatile fatty acids (VFA) was studied in vitro to assess the possible contribution of microbial fermentation to the energy economy of growing ostrich chicks. Structure, capacity and contents of the gastro-intestinal track were examined to identify major…
