Journal ArticleDOI

Feeding diets varying in forage proportion and particle length to lactating dairy cows: I. Effects on ruminal pH and fermentation, microbial protein synthesis, digestibility, and milk production.

Chun Li, +2 more
- 01 May 2020 - 
TL;DR: The results indicate that feeding dairy cows a low F:C diet helps increase DM intake, milk production, and microbial protein synthesis, but may adversely affect feed digestibility and milk efficiency due to increased risk of subacute ruminal acidosis.
Journal ArticleDOI

Optimum extent of barley grain processing and barley silage proportion in feedlot cattle diets: Growth, feed efficiency, and fecal characteristics

K. M. Koenig, +1 more
- 01 Sep 2011 - 
TL;DR: Formulating diets to reduce the incidence of digestive disorders may decrease the cost of mortalities and treatment of sick animals, thereby improving animal health and welfare, but these costs are unlikely to offset the increased cost of gain in commercial feedlots.
Journal ArticleDOI

Impact of strain and dose of lactic acid bacteria on in vitro ruminal fermentation with varying media pH levels and feed substrates

P.X. Jiao, +4 more
- 01 Feb 2017 - 
TL;DR: In this paper, the authors evaluated the effects of five live lactic acid bacteria (LAB; LAB1, LAB2 and LAB3) on gas production kinetics, dry matter (DM) disappearance (DMD), volatile fatty acid (VFA) and NH 3 -N concentrations in batch culture.
Journal ArticleDOI

Milk production, nitrogen utilization, and methane emissions of dairy cows grazing grass, forb, and legume-based pastures.

Randi L Wilson, +5 more
- 01 Jul 2020 - 
TL;DR: Forb pasture can support animal performance, milk quality, and health, comparable to Legume pasture; however, Forb pasture provides the additional benefit of reduced environmental impact of pasture-based dairy production.
Journal ArticleDOI

Liquid hot water treatment of rice straw enhances anaerobic degradation and inhibits methane production during in vitro ruminal fermentation.

Xiu Min Zhang, +8 more
- 01 May 2020 - 
TL;DR: The LHW treatment is a potential strategy to improve the nutritive value of forage such as rice straw and decrease the CH4 emissions in ruminants.
