“…However, Taylor et al (1960) Urness et al (1977) reported that the Tilley and Terry technique yielded dry matter digestion indices that were significantly lower than those of conventional trials. Van Dyne (1962) found good agreement between the Tilley and Terry and nylon bag procedures.…”

Aboveground biomass of four range species was collected at several phenological stagesand total nitrogen wasdetermined. The dissolvable nitrogen fraction within these samples was estimated utilizing four techniques: (1) in vivo nylon bag digestion in a rumen-flstulated Bison bison; (2) in vitro Tllley and Terry plus pepsin; (3) neutral detergent fiber; and (4) laboratory detergent fiber. Total nitrogen concentration in all plant species studied was highest during early growth and decreased with advancing maturity. A similar amount of nitrogen was removed from dead or dormant plant materials using any technique, but significantly more nitrogen was removed from green succulent material utilizing the nylon bag technique than was removed with the three laboratory assays. The amount of nitrogen removed from plant foliage was highly correlated among techniques. Equations were developed to predict nitrogen losses with the nylon bag technique using dissolved nitrogen values obtained from any of the other three techniques.

“…The use of degradation characteristics as a means of formulating ration combinations for ruminants becomes an aide or guide especially for those nutritionists. Several researchers employing the nylon-bag technique [11] [12] [13] to study ruminant digestion use a specific basal diet so as to minimize any variations between animals and different trial periods within animals. However, while the results gained do indicate relatively dry-matter digestibility (DMD) of forages, Journal of Agricultural Chemistry and Environment they do not represent natural conditions where the animals are free-ranging and there is variation in basal diets and hence in DMD efficiencies.…”

The study aimed to explore the potential of dietary fats supplementation on the overall goat performance. Three (3) mature rumen-cannulated goats weighting 27.33 ± 1.53 kg housed in individual elevated metabolism stalls with customized fecal and urine collection tools with treatments replicated three times over time following the Complete Randomized Design (CRD). Animals were randomly selected on different dietary treatment at different cycle. For each cycle, animals were provided with 30% concentrate on the morning based on feed requirements {3% of their body weight (BW) dry matter (DM) basis} of the animals. Ad libitum feeding of Napier grass will follow thereafter. Clean drinking water were made available all the times in the respective animal watering troughs. The rumen-cannulated goats were supplemented with different levels of two dietary fats (VCO and Lard) with dietary treatment combinations as follows, Control and VCO and Lard at 3% & 5%. Degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were collected sequentially in every cycle of the study. There were seven (7) days lag period in every cycle for the animals to return to each natural state. On the 8th day of every cycle, animals were given different dietary treatment. Sequential insertion of nylon bag was done on the 15th to 16th day (7 days after treatment). The results showed that degradability of the dry matter (DM) was noticed degraded exponentially on the first twelve hours of incubation and slower down in the next few hours until 48 hours. Crude protein, acid and neutral detergent fiber showed breakdown of components was observed in the first 48 hours of incubation. No significant difference (P > 0.05) among treatment means was observed in all parameters gathered. This implies that mature female goat diet How to cite this paper: Ningal, N.L.

A digestion technique using a commercially-available crude cellulase preparation from Trichoderma viride is described. The enzyme showed cellulase, hemicellulase and proteolytic activity when tested on herbage or herbage polysaccharides. A high correlation (r = 0.92, P < 0.001, residual standard deviation 2.5) was found between a simple one stage enzyme digestion and in vivo dry matter digestibility for a range of grass species and varieties. In vitro dry matter digestibility and detergent fibre were also determined on the same samples and the results correlated with in vivo dry matter digestibility. The cellulase method is rapid and reproducible and particularly well suited for the evaluation of plant material in breeding programmes.
