The present study was planned to evaluate the chemical composition and nutritive values of commonly available pulse chunies of Green gram (GGC), Black gram (BGC), Bengal gram (BnGC) and Red gram (RGC) available in the local markets of Hyderabad, Andhra Pradesh. These chunies were subjected to chemical analysis followed by measurement of in vitro gas production (IVGP) with sheep rumen liquor. By calculation, in vitro organic matter digestibility (IVOMD), total digestible nutrient (TDN), Metabolizable Energy (ME) was determined. DM (P<0.001), CP (P<0.001), CF (P<0.001), TA (P<0.001), NDF (P<0.001), ADF (P<0.001), cellulose (P<0.01), hemicelluloses (P<0.001), lignin (P<0.01) silica (P<0.001) and Ca (P<0.05) varied significantly. The cumulative gas production in IVGP technique at 0-2, 0-4, 0-6, 0-8, 0-12 and 0-18h incubations varied significantly. The TDN and ME content were highest (P<0.01) in GGC. IVOMD (mg/24h) was comparable (P>0.05) among them. The study concluded that these chunies are good energy sources. GGC was the best with respect to its energy and organic matter digestibility among these. High protein and energy contents of BGC and GGC signified that these can be a good feed replacement of concentrates for livestock feeding.

Micro Organisms

A previous study (Mauricio et al., 1998) with 12 forage substrates (straw, hay and dried grasses) showed a high correlation between rumen liquor and faeces for total gas production and in vitro organic matter digestibility (OMD). However parameters estimated using faecal inoculum were generally lower man when using rumen liquor. To confirm this observation, a second study was conducted using maize silage and silages made from maize plant fractions.

Different Levels

The objective of this study was to evaluate the effects of different levels of Vitex agnus-castus (VAC) on in vitro gas production (GP), organic matter digestibility (OMD) and net energy lactation (NEL) using an in vitro gas-production method. Two rumen-fistulated sheep were used in the experiment. The sheep were fed 60% alfalfa hay and 40% concentrate feed twice daily. Five different levels of VAC were added to the concentrate (CON) to produce 200 mg DM (CON - without VAC; 1 - 2 mg VAC+198 mg CON; 2 - 4 mg VAC+196 mg CON; 3 - 6 mg VAC+194 mg CON; 4 - 8 mg VAC+192 mg CON; 5 - 10 mg VAC+190 mg CON). The volume of gas produced was recorded at 2, 4, 8, 12, and 24 h after incubation. The results showed GP, OMD and NEL contents with no significant changes even as the level of VAC were added to the CON. VAC groups affected the rapidly degraded fractions; however, did not affect the slowly degraded fractions.
