“…Crop residues are generated in huge quantities as a primary byproduct of intensive agricultural production system. For example, in India about 523 Mt per annum crop residue is generated [12]. Crop residues of low lignocellulosic composition are used as a resource either in manure/compost preparation or as cattle feed.…”

“…Crop residues of low lignocellulosic composition are used as a resource either in manure/compost preparation or as cattle feed. But, substantial quantities of high lignocellulosic residues of crops such as pigeon pea (9 Mt per annum in India) and sunflower (1 Mt per annum in India) are neither used for feeding cattle nor preparing manure [12]. Keeping these large volumes of high lignocellulosic crop residues in field often cause obstruction for agro-machinery/ implements and also harbors pests.…”

In the quest for identifying low‐cost, locally available and effective adsorbents, pigeon pea (Cajanus cajan L.) residue ash (PRA) and sunflower (Helianthus annuus L.) residue ash (SRA) were evaluated as adsorbents for sequestering a basic dye, methylene blue (MB), from aqueous solution. Effects of contact time, initial solution pH and adsorbent dose on MB adsorption were investigated. MB adsorption onto PRA and SRA was dependent on initial solution pH, with adsorption being greater at higher pH. Percent MB removal increased with increase in adsorbent's dose. Adsorption followed pseudo‐second order kinetics. Intraparticle diffusion was not the sole rate‐controlling step. Both film diffusion and intraparticle diffusion controlled the adsorption process. The equilibrium data fitted well to Langmuir isotherm as compared to Freundlich isotherm, on the basis of coefficient of determination and error analysis. The maximum MB adsorption capacities of PRA and SRA were found as 58.8 and 62.5 mg g−1, respectively. The free energy change and dimensionless equilibrium parameter revealed spontaneous and favorable nature of MB adsorption onto crop residue ashes. Results demonstrate that the PRA and SRA have high adsorptive potential as compared to many previously reported ash based adsorbents, and hence can be used for treating water contaminated with cationic dyes.

“…Leaf fibres of pine apple (Bhaduri et al, 1979) and sisal used in textile industries are quite different from the fibres reported here. Pathak et al (1986) reported the chemical and mineral composition of a variety of agricultural by-products such as wheat and rice straw, rice husk, arhar and maize stalks, groundnut shell etc. which are very similar to those of the fibres reported here (Tables 1 and 3).…”

SYNOPSISLeaffibre residues obtained as a by-product during bulk extraction ofleafprotein meal from three tropical forest trees viz. Albizzia procera Benth., Dalbergia sisso Roxb. and Delonix regia Raf. were analysed for their chemical and mineral composition. The fibres were found to consist oflignin, a-cellulose, pentosan, lipids, minerals, etc. and were similar in chemical nature. The data were compared with those of other lignocellulosic wastes and agricultural by-products like straw, husk, bagasse,jute stick, fibres, wood etc., which are commercially used in the preparation of feed, pulp, particle board, paper and composts.

“… Pathak et al (1986) compared the bulk density, equilibrium moisture content (EMC) at 80% relative humidity and gross energy of maize cobs with other crop residues such as Arhar stalks, cotton sticks, maize stalks and rice straw. The EMC describes the moisture state of a hygroscopic material as it equilibrates on a moisture basis with its environment and has implications on shelf life ( Igathinathane et al, 2005 ).…”

The quest to broaden the narrow range of feed ingredients available to pig producers has prompted research on the use of low cost, unconventional feedstuffs, which are typically fibrous and abundant. Maize cobs, a by-product of a major cereal grown worldwide, have potential to be used as a pig feed ingredient. Presently, maize cobs are either dumped or burnt for fuel. The major challenge in using maize cobs in pig diets is their lignocellulosic nature (45% to 55% cellulose, 25% to 35% hemicellulose, and 20% to 30% lignin) which is resistant to pigs’ digestive enzymes. The high fiber in maize cobs (930 g neutral detergent fiber/kg dry matter [DM]; 573 g acid detergent fiber/kg DM) increases rate of passage and sequestration of nutrients in the fiber reducing their digestion. However, grinding, heating and fermentation can modify the structure of the fibrous components in the maize cobs and improve their utilization. Pigs can also extract up to 25% of energy maintenance requirements from fermentation products. In addition, dietary fiber improves pig intestinal health by promoting the growth of lactic acid bacteria, which suppress proliferation of pathogenic bacteria in the intestines. This paper reviews maize cob composition and the effect on digestibility of nutrients, intestinal microflora and growth performance and proposes the use of ensiling using exogenous enzymes to enhance utilization in diets of pigs.
