“…Improving roughage quality can also significantly lower CH4 emissions from animal enteric fermentation. Na et al [11] compared the effects of different straw roughage and maize silage roughage on enteric CH4 emissions from dairy cows. The results showed that with the same roughage to concentrate ratio, CH4 emissions of maize silage rations was 20% lower than with of straw-based rations.…”

“…Changing concentrate-to-forage ratio (CTFR) in the ration of ruminants, improving the quality of forage, and promoting whole-plant maize silage can effectively improve feed digestibility for dairy cows and reduce emissions of CH4 from enteric fermentation. Previous reviews indicate that maize silage as the forage source at CTFR of 4:6 can reduce enteric CH4 emissions by more than 20%, compared with dry maize stalks [11] . The conversion rate for enteric fermentation CH4 can decrease from 6.5% to below 6%.…”

Animal husbandry is a major source of greenhouse gas (GHG) emissions in agriculture. Mitigating the emissions from the livestock sector is vital for green development of agriculture in China. Based on National Communication on Climate Change of United Nations, this study aims to investigate the characteristics of GHG emissions of animal husbandry during 1994 to 2014, introduce major emission reduction technologies and their effectiveness, and investigate options for emission reduction for the livestock sector in China. It proposes that control of pollution and carbon emissions can be realized through increased animal productivity, improved feed quality and recycling of animal manure. This paper thus concludes with suggestions of green and low-carbon development of animal husbandry, including the research and development of new technology for emission reduction and carbon sequestration of the livestock sector, enhancement of monitoring and evaluation, and establishment of emission reduction and carbon sequestration standards.

The objective of current study was to evaluate effect of Saccharomyces cerevisiae (SC) on rumen fermentation characteristics and fiber degradation in steers fed diets with different concentrate levels. Ten Simental × Local breed steers fitted with rumen fistulas were assigned to control and treatment groups. Steers were fed the same basal diets but the treatment groups received SC supplementation (8×10 9 cfu/h/d) following a 2-period crossover design. Each period was comprised of four phases. From the 1 st to the 4 th phase, steers were fed in a stepwise fashion with incremental levels of concentrate diets at concentrate to forage ratios (CTFR) of 30:70, 50:50, 70:30 and 90:10, respectively. MIXED procedure was used to analysis effect of SC supplementation on parameters. Linear and quadratic responses for dietary CTFR were assessed using orthogonal polynomial contrast statements. The results showed that with dietary CTFR increasing, rumen pH, acetate and isobutyrate molar proportion, acetate: propionate, degradation rate (c DM , c NDF ) and effective degradability (ED DM , ED NDF ) of CRH linearly decreased (L; P < 0.01); TVFA concentration, molar proportion of propionate, butyrate, valerate and isovalerate and enzyme fibrotic activities linearly increased (L; P < 0.01), but concentration of rumen ammonia N, D+L-lactate and rapidly degradable fraction (a DM , a NDF ) of CRH presented quadratic variation (Q; P < 0.01). Regardless of dietary CTFR, rumen pH, c DM , c NDF , ED DM , ED NDF of CRH and enzyme fibrotic activities with SC supplementation was higher compared to control groups (P < 0.05). Overall, SC possesses the capacity to stabilize rumen pH and to enhance fiber degradation.
