The chemical composition and dry matter (DM) and nitrogen (N) degradation characteristics of four diet combinations ar four total digestible nutrients (TDN) levels of cottonseed cake (CSC), dried brewer's grains (DBG) and Lablab purpureus hay (LL) which were fed to ruminants in the humid zone of Ibadan, South-west Nigeria, were evaluated. TheTDN levels used were 3.5, 4.5, 5.5 and 6.5 kg TDN. The CSC and DBG used are agro-industrial by-products which are used in feeding livestock while the LL is a leguminous plant which is not used much as human feed but is usually grown as forage legume for animal feeding. The completely randomized design with four treatments and three replicates was used. The experiment was carried out In Ibadan, South-western Nigeria during the wet season (June to July). The diets were high in crude protein contents so that they had high nutritional potential for ruminants feeding and productivity. The potential degradability (PD) of dry matter (DM) values ranged from 75. 24 to 79.47 g/100g DM, while that for the nitrogen (N) degradability ranged between 88.36 and 94.30 g/100g N. The soluble fraction value of DM degradation and the crude fibre (CF) content of the chemical composition of the diets were significantly correlated (r=0.644; P=0.007). The potential degradability (PD) values for both the DM and N degradabilities were significantly (P>0.05) different among the four treatment diets combinations.

The experiment was aimed to predict the relationship between rumen degradation parameters and chemical composition, especially acid detergent lignin, and molecular structure profiles of lignin (the relative content ratio of syringyl and guaiacyl unit) of twenty-two herbaceous and leguminous forage, which were commonly used as roughage for dairy cows in the northeast of China. Analyses of the spectra of forage materials' high boiling solvent lignin samples showed that common features and specific vibrations to each unique lignin were found in the spectrum. In this paper, the spectra of materials high boiling solvent lignin demonstrated absorption at the band around 1332 cm–1 (syringyl) and 1258 cm–1 (guaiacyl). The spectra indicated that the lignin of the plant materials used in this study are H-G-S type. A broad range was found among the chemical composition for each feedstuff. The degradation kinetics characteristics among feedstuffs also had relatively large range of variation. The relative content ratio of syringyl (S) and guaiacyl (G) unit of leguminous samples positively correlated with some rumen degradation characteristics. However, there was no correlation between relative content ratio of S and G unit and degradation parameters among the herbaceous materials (p > 0.05). According to analyses, content acid detergent lignin (ADL) and relative content ratio of S and G could be the predictors of the degradation parameters expect SCP among forage. In conclusion, the relative content ratio of S and G might be potentially used to predict some of the degradation parameters (Kd CP, EDCP, SNDF) of leguminous feedstuffs.

This study aimed to identfy chemical composition, ruminal degradation characeristics and metabolizable energy (ME) content of five different chickpea line and a check cultivar’s straw using nylon bag technique. Feed samples were incubated as three replicates of each fistulated Holstein heifer for 0, 8, 12, 24, 36, 48, 72 and 96 h. Degradation characteristics of dry matter (DM) and neutral detergent fiber (NDF) in rumen were determined by using this mathematical expression D=a+b(1-e-ct). Crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), and ash contents of straw were ranged from 5.61 to 7.42%, 51.33 to 56.0%, 63.67 to 67.0%, and 8.0 to 9.0% respectively. Besides Rapidly soluble fraction (a), potantial degradability (a+b) and effective dry matter degradability (EDDM ) were ranged from 17.86 to 21.41, 54.40 to 59.43, 49.65 to 54.91% respectively. Estimated ME of chickpea entries straw were ranged from 5.96 to 7.37 MJ/kg. Metabolizable energy content of control chickpea cultivar was significantly higher than the other chickpea straw of lines. The research values of ME revealed that significant differences were determined among the lines in terms of energy content. In addition to, a strong relationship between straw NDF level and ME content were determined.

The Difference

ABSTRACTTwo varieties of barley straw, Corgi and Gerbel, which varied in degradability when incubated in the rumen in nylon bags, were chosen for further examination of botanical fractions and to see how each fraction responded to treatment with ammonia. The straws were separated into leaves, internodes, nodes and chaff. The average proportions of these fractions were respectively 0·499, 0·380, 0·055 and 0·065 in Corgi straw and 0·404, 0·512, 0·059 and 0·025 in Gerbel straw. For both varieties the degradability of the botanical fractions were leaves > chaff > nodes > internodes.Despite a similar chemical composition, the dry-matter loss (DML) values of leaves, internodes and nodes of Corgi were higher than those of Gerbel straw.The differences between varieties were larger for internodes and nodes than for leaves. The difference in DML of the two varieties at 48-h incubation was 132 g/kg DM. Of this difference, 25 g were due to differences in distribution of the botanical fractions and 107 g to differences in DML of the fractions.Ammonia treatment significantly increased the DML of all fractions except the nodes. The overall improvement due to ammonia treatment of the different fraction was internode > chaff > leaves > nodes.
