“…Anaerobic fungi have been isolated from a number of ruminant and nonruminant herbivorous mammals (Ljungdahl 2008 ;Paul et al 2010 ). These contribute signifi cantly to overall metabolism of host with their high cellulolytic activity and play a greater role in degradation of lignifi ed plant tissues (Akin and Borneman 1990 ; Dey et al 2004 ;Thareja et al 2006 ;Sirohi et al 2012b ) with the help of a wide range of hydrolytic enzymes (Tripathi et al 2007b ;Shelke et al 2009 ;Nagpal et al 2009Nagpal et al , 2010Nagpal et al , 2011 including cellulases (Barichievich and Calza 1990 ), hemicellulases (Novotna et al 2010 ;Mountfort and Asher 1989 ), proteases (Michel et al 1993 ), amylases, amyloglycosidases (Paul et al 2004 ), feruloyl and p-coumaroyl esterases (Borneman et al 1990 ), various disaccharidases (Chen et al 1995 ), and pectinases (Kopecny and Hodrova 1995 ). To date, only six genera (Table 1.2 ) have been described (Griffi th et al 2009 ;Sirohi et al 2012b ).…”

The systematic exploration of microbial ecosystem of the rumen was commenced by the father of rumen microbiology, Robert Hungate, in 1950s. His contributions toward the development of anaerobic culture techniques have illustrated the ways to explore the complex microbial structures of the rumen and other anaerobic ecosystems. The understanding of rumen microbiology has strengthened an awareness to improve the feed utilization and manipulation of microbial compositions. Microbes and their interactions in interspecies H 2 transfers were fi rst studied in the rumen ecosystems and attracted pioneers to investigate the alternate abatement strategies of methane production along with enhanced animal productivity. The discovery of alternate hydrogenotrophs and industrially important novel microbes and the management of rumen disorders via microbial manipulations make this community an interesting research platform for different microbial theories. The discovery of anaerobic fungi as a part of rumen fl ora by Orpin during the 1970s disproved their mistaken identity as fl agellated protozoa and the concept that all fungi are aerobic organisms.

“…The rumen habitat is characterized by complex microbial communities with a large degree of overlap in substrate degradation capabilities and cross-feeding nets (Hungate et al 1988;Stahl et al 1988;Tajima et al 2000;Ziemer et al 2000;Sadet et al 2007;Lanyasunya et al 2007;Comlekcioglu et al 2008;Shelke et al 2009). The structure and diversity of rumen microbiota is strictly influenced by animal feeding behavior.…”

The aim of the present study was to investigate the possible effects of a diet containing transgenic corn (Zea mays), cultivar Bt176 expressing the insecticidal protein CryIA(b), on bacterial diversity of the cow rumen in vivo. Silage prepared with Bt176 corn and its parental non-transgenic cultivar showed no significant differences in either composition or in vivo degradability. Four cows were fed for 35 days with the different silage in a cross-over feeding experiment. The overall structure of rumen bacterial populations was analyzed using a cultivationindependent approach-ribosomal intergenic spacer analysis (RISA)-during 3 consecutive days of each feeding trial in all cows. Planktonic bacterial populations present in the rumen fluid and biofilm grown directly on the silage were analyzed separately. Statistical analysis of RISA fingerprints did not reveal significant differences in bacterial community structure between different feedings. Small differences were nevertheless observed between individuals on the structure of bacterial communities directly colonizing the silage material. A diet constituted by transgenic Btcorn silage was demonstrated not to be substantially different from non-transgenic corn silage in terms of composition, digestibility and impact on the overall rumen microbiota.

“…Moreover, bagasse is highly produced from industry processing (Thai Sugar Mill, 2007), and if mixed with vinasse should increase the dry matter content and it could be easily supplied to animals in the form of bagasse–vinasse mixture. However, bagasse is the highly fibrous residue remaining after sugar cane is pressed to remove sucrose (Martin et al, 2007) and results in low protein and high in cellulose (Shelke et al, 2009; Kumari et al, 2013). Therefore, bagasse–vinasse mixture (BV) should increase the bagasse quality.…”

Silages from pineapple peel, sweet corn husk and cob mixed with bagasse and vinasse were evaluated to determine their chemical composition and fermentation characteristics as well as feeding performance in fattening steers. The experiment, which lasted 90 days, involved 48 fattening steers (264 ± 37.4 kg BW) randomly allocated to three diets. Treatments included: a control diet containing rice straw and molasses (T1); diet containing bagasse-vinasse mixture including sweet corn husk and cob silage (BS; T2); and diet containing bagasse-vinasse mixture including pineapple peel silage (BP; T3). All treatments included a commercial concentrate feed (13% CP) and ad libitum rice straw throughout the experiment. Results from chemical analysis showed that dry matter (DM) of BS was higher than BP (P < 0.05), whereas the protein content of BS and BP was similar (P> 0.05). For fermentation characteristics, pH in BP was lower than BS (P < 0.05); in addition, acetic and butyric acids in BS were higher than BP (P < 0.05). Findings from growth trial showed that total DM intake in steers fed T1 was higher compared to the other dietary treatments (P < 0.05), whereas the average BW gain was found to be grater in T3 steers (P < 0.05). As result from our findings, bagasse-vinasse mixture with pineapple peel silage appeared to be a viable feed ingredient in fattening steer diet and moreover it could become an economically feasible agro-industrial by-product for farmers.
