| 1 | Dietary sources and their effects on animal production and environmental sustainability显示文摘Animal agriculture has been an important component in the integrated farming systems in developing countries. It serves in a paramount diversified role in producing animal protein food, draft power, farm manure as well as ensuring social status-quo and enriching livelihood. Ruminants are importantly contributable to the well-being and the livelihood of the global population. Ruminant production systems can vary from subsistence to intensive type of farming depending on locality, resource availability,infrastructure accessibility, food demand and market potentials. The growing demand for sustainable animal production is compelling to researchers exploring the potential approaches to reduce greenhouse gases(GHG) emissions from livestock. Global warming has been an issue of concern and importance for all especially those engaged in animal agriculture. Methane(CH_4) is one of the major GHG accounted for at least 14% of the total GHG with a global warming potential 25-fold of carbon dioxide and a 12-year atmospheric lifetime. Agricultural sector has a contribution of 50 to 60% methane emission and ruminants are the major source of methane contribution(15 to 33%). Methane emission by enteric fermentation of ruminants represents a loss of energy intake(5 to 15% of total) and is produced by methanogens(archae) as a result of fermentation end-products. Ruminants' digestive fermentation results in fermentation end-products of volatile fatty acids(VFA), microbial protein and methane production in the rumen. Rumen microorganisms including bacteria, protozoa and fungal zoospores are closely associated with the rumen fermentation efficiency. Besides using feed formulation and feeding management, local feed resources have been used as alternative feed additives for manipulation of rumen ecology with promising results for replacement in ruminant feeding. Those potential feed additive practices are as follows: 1) the use of plant extracts or plants containing secondary compounds(e.g., condensed tannins and saponins) such as mangosteen peel powder, rain tree pod; 2) plants rich in minerals, e.g., banana flower powder; and 3) plant essential oils, e.g., garlic, eucalyptus leaf powder, etc. Implementation of the-feed-system using cash crop and leguminous shrubs or fodder trees are of promising results. | Metha Wanapat Anusorn Cherdthong Kampanat Phesatcha Sungchhang Kang | 2015 | Animal Nutrition2015，，3： | 5 |

| 11 | Effect of ground corn cobs as a fiber source in total mixed ration on feed intake,milk yield and milk composition in tropical lactating crossbred Holstein cows显示文摘The aim of this study was to evaluate the effect of ground corn cobs(GCC) as a sole fiber source in total mixed ration(TMR) on feed intake, milk yield and milk composition in tropical lactating crossbred Holstein cows. Four multiparous crossbreds Holstein Friesian dairy cows with an initial body weight(BW) of 415.5 ± 26.20 kg were used in a 4 x 4 Latin square design. The dietary treatments of TMR contained a roughage-to-concentrate ratio of 40:60. The roughage source was used at different ratios of GCC to rice straw(RS) at 100:0, 82.5:17.5, 67.5:32.5, and 50:50 for TMR1 to TMR4, respectively. The results revealed significant improvements in intake of dry matter, protein,neutral detergent fiber(NDF)and metabolizable energy(ME) for TMR1 and TMR2(P < 0.05), while the digestibility of nutrients was not altered by the treatments(P > 0.05). Ground corn cobs was used for up to 100% of the total roughage without affecting milk production. Moreover, ruminal pH, temperature, ammonia-nitrogen(NH_3-N) and volatile fatty acid(VFA) concentrations were not impacted by the treatments(P> 0.05). However, milk yield was significantly different among the GCC:RS ratios(P < 0.05) and was the highest in TMR1 and TMR2(13.1 kg/d), while the milk compositions were not changed(P > 0.05). The results imply that using GCC as a whole roughage source significantly improved nutrients intake and milk yield in dairy cows raised in tropical areas. | Chalong Wachirapakorn Krung Pilachai Metha Wanapat Pawadee Pakdee Anusorn Cherdthong | 2016 | Animal Nutrition2016，，4： | 1 |

| 15 | 日粮中添加香茅粉对肉牛瘤胃生态的调节显示文摘试验旨在研究香茅(Cymbopogon citratus Stapf.)粉(LGP)对瘤胃生态,瘤胃微生物和营养物质的消化率的影响。试验采用4×4拉丁方设计,选择4头安有瘘管的杂交肉牛(波罗门牛)并随机分配。设4个日粮处理组,LGP添加水平分别为0、100、200、300g·d^-1,结合尿素处理的稻草(5%)一起饲喂,试牛自由采食。试验结果显示:各处理间干物质(DM)、粗脂肪(EE)和中性洗涤纤维(NDF)的可消化性差异显著,以添加LGP100g·d^-1组最高。然而,添加LGP使粗蛋白质(CP)的可消化性显著降低(P〈0.05),且随着LGP添加量的升高,瘤胃中氨氮和尿素氮含量显著降低(p〈0.05)。 | Wanapat M Cherdthong A Pakdee P Wanapat S | 2008 | 饲料博览(技术版)2008，，12： | 0 |
