Organic Matter Digestibility

Seventy samples of browse feeds, collected during late autumn and spring of 1971 from 42 western Queensland shrubs and trees, were subjected to laboratory analyses of the proximate fractions and in vitro digestibility. Crude protein, crude fibre and nitrogen-free-extract fractions ranged between 65 and 242, 55 and 353 and 425 and 71 1 g kg-1 dry matter, repectively. The in vitro dry matter digestibility coefficients ranged between 0.22 and 0.86. Comparisons of 15 browse feeds collected in April-May and October indicated a higher crude protein content (P < 0.05) and in vitro digestibility (P .= 0.01) and lower crude fibre (P < 0.01) and ash (P < 0.01 ) content in spring samples for most species. Nine browse feeds of known in vivo dry matter and organic matter digestibility were subjected to in vitro digestibility analysis. Whilst the in vitro and in vivo dry matter digestibilities were similar (0.43 and 0.45, respectively) the mean in vitro organic matter digestibility was substantially lower than the corresponding in vivo digestibility (0.40 and 0.46, respectively).

Organic Matter Digestibility

This experiment was aimed to study the effect of nutmeg leaf tannin addition on in vitro nutrient digestibility. Treatments in this experiment consisted of: P0 (control without tannin), P1 (feed + 2% tannin) and P2 (feed + 4% tannin). Feed for fermentation substrate consisted of Pennisetum purpureum and soybean meal with ratio 60:40. Fermentation was carried out using Tilley and Terry two stages in vitro technique for 48 hours. Variables measured were the digestibility of dry matter, organic matter, and crude protein in the rumen as well as the total digestive tract digestibility based on in vitro technique. The data obtained were analyzed by One Way ANOVA, and followed by the Duncan Multiple Range Test (DMRT). The results showed that rumen dry matter digestibility was lower (P<0.05) in P1 and P2 (59.03±3.24 and 57.19±1.32) compared to P0 (70.77±1.05), but did not show a significant difference (P>0.05) in the total dry matter digestibility of P0, P1, and P2 (74.88±5.28, 67.70±3.21, and 64.83±4.96). Organic matter digestibility in the rumen was also lower (P<0.05) in P1 and P2 (55.55±6.29 and 55.76±6.88) compared to P0 (75.39±0.91), but did not show significant difference (P>0.05) in total organic matter digestibility from P0, P1, and P2 (64.69±6.44, 64.33±6.34, and 61.20±5.11). The digestibility of crude protein in the rumen at P1 and P2 (45.48±5.12 and 38.47±3.44) was also significantly lower (P<0.05) compared to P0 (60.93±9.72), whereas total digestibility did not show any significant difference (P>0.05). Addition of tannin leaf nutmeg 2% optimally reduced rumen dry matter and crude protein digestibility without causing excessive negative impact on results of in vitro digestibility, so it can be used as a protective agent protein feed.

The study aimed to determine invitro digestibility, volattyle fatty acid (VFA) and ammonia (NH3) of corn straw silage with different storage periode. The experiments use a completely randomized design (CRD) with four treatments and each treatment was repeated five times, so there are 20 experimental units. The fourth treatments are W1 = storage time of 14 days, W2 = storage time of 21 days, W3 = storage time of 28 days, and W4 = storage time of 35 days. The parameters observed in this study in-vitro digestibility including dry matter and organic matter digestibility, VFA, and NH3. Results of the experiment showed that dry matter digestibility showed significant differences, otherwise organic matter digestibility, VFA, and NH3 were not significantly different, and there was a tendency to decrease the value of dry matter and organic matter digestibility, VFA, and NH3 with longer duration of storage of corn straw silage. It can be concluded that dry matter, organic matter digestibility VFA, and NH3, are not significant different. Keywords: corn straw, silage, storage periode, invitro digestibility, VFA, NH3

This study aimed primarily to investigate the effect of Zn-Proteinate (Zn-Prot) supplementation on in vitro rumen digestibility and rumen fermentation. This research used a completely randomized design with four treatments and four replicates. The experimental treatment was the supplementation of various levels of Zn-Prot (0; 12.5 ppm; 25 ppm, and 37.5 ppm) on a dry matter basis. Parameters determined were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), partial volatile fatty acid (VFA) (acetate, propionate, and butyrate), A/P ratio, CH4, and the efficiency of the conversion hexose to VFA. Data were analyzed using ANOVA. The results showed that goats fed with a diet supplemented with 25 ppm Zn-Prot had the highest IVDMD and IVOMD values. There was no significant effect on the VFA and CH4 concentrations, A/P ratio, and the efficiency of the hexose-VFA conversion within treatment groups. In conclusion, supplementing 25 ppm of Zn-Prot into the diet of dairy goat increase the dry matter and organic matter digestibility.

APBN1, a variety of hybrid napier was analysed at five stages of harvest (30, 40, 45, 50 and 60 days) for yield, leaf to stem ratio, chemical composition, in vitro dry matter digestibility, in sacco dry matter and protein degradation to find out optimum stage of harvesting. The yield of green fodder, dry matter (DM) and crude protein (CP) (MT/ ha/year) of forage harvested at 30, 40, 45, 50 and 60 days of growth ranged from 274.68 to 387.95, 47.35 to 98.81, 7.44 to 11.45, respectively. Highest (P less than 0.05) CP yield (11.45 MT/ha) and nitrogen free extract content (46.12%) was observed at 45 d of growth. Crude protein (15.72 to 11.34%), ether extract (3.65 to 2.26%) decreased, whereas total ash (10.88 to 13.86%), crude fibre (23.81 to 29.88%) and acid insoluble ash (3.92 to 5.14%) levels increased when forage was allowed to grow from 30 to 60 d. Similarly, NDF, ADF, hemicellulose, cellulose, lignin and silica levels also increased gradually as plant matures. The in vitro dry matter digestibility was maximum (57.87%) at 30 d and minimum (51.40%) at 60 d of growth. Effective dry matter and protein degradability decreased from 55.80 to 43.78 and from 38.30 to 33.17 per cent, respectively as plant matured from 30 to 60 days. The insoluble but degradable protein fraction ‘b’ was highest (77.07%) at 45 d of growth. Based on the biomass yield, leaf to stem ratio, chemical, in vitro and in sacco evaluation, the optimum stage of harvesting for APBN1 forage was found to be at 45 d of growth.

Apparent Digestibility

1. Grass from the same sward was ensiled without additive, with 14.6 g formic acid/100 g crude protein or 10.8 g formic acid and 10.6 g formaldehyde/100 g crude protein. Similar grass was dried and pelleted. Drying or ensiling with the mixture reduced solubility of N in the preserved grass but formic acid increased it, and ensiling without additive increased it even more. Apparent digestibility of N in the rumen of cows tended to decrease with decrease in solubility. Digestibility in vitro of the mixed diet given to the cows, calculated from digestibility of the separate components, agreed well with the values in vivo for diets with silages, but was high for that with dried grass.
