Non-destructive foliar chlorophyll measurement has the potential to predict crude protein concentration and in vitro ruminal organic matter digestibility in Bracharia decumbens herbage

The purpose of this experiment was to investigate herbage production and nutritive value of C. ternatea harvested at 60, 75 and 90 days after planting. The legume was planted in eighteen of 3 × 3 m2 plots a t 40 × 20 cm2. Forage was harvested at 60, 75 and 90 days after planting as treatmens. Variables measured included forage production, nutrient content and in vitro dry matter and organic matter digestibility. Herbage production was not significantly different (P>0.05) when harvested at different stages of growth. Leaf : stem ratio, however, declined (P<0.05) with advancing growth stage. Forage quality in terms of crude protein content was comparable (P>0.05) among different harvest time. Meanwhile the energetic value as shown by in vitro organic matter digestibility (IVOMD) was significantly higher (P<0.05) when C. ternatea was harvested 60 days compared to 75 and 90 days after planting. It can be concluded that for calf supplement, C. ternatea is preferably harvested at 60 d after planting. Key words : Clitoria ternatea, IVOMD, energy, calf supplement

Objective: This study aims to determine the nutritional value and nutrient digestibility by in vitro of fodder sorghum (Sorghum bicolor (L.) Moench) from the effect of the addition of fermented urine fertilizer to the hydroponic media.Methods: The research used sorghum Numbu varieties grown hydroponically in the fodder phase, which was carried out in June - September 2020. The research treatments consist of water medium (T1), fermented urine 12.5 mL/L (T2) and 25 mL/L media (T3) with 4 replications. The urine fertilizer used was derived from fermented Ongole Crossbreed cow urine for 21 days. Fodder sorghum planted for 15 days. The results of the fodder harvest were analyzed by proximate and in vitro nutrient digestibility. Observation nutritional value parameters consists of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF), total nutrient digestible (TDN), dry matter digestibility (DMD) and organic matter digestibility (OMD). Data were analyzed using one way ANOVA design, the significance by Duncan's Multiple Range Test.Results: The results showed that the addition of fermented urine had no effect on the DM, OM, and EE, but had a significant effect (P <0.05) on CP, CF, TDN and nutrient digestibility. The T2 and T3 treatments increased crude protein by 6.31% and 11.23% compared to T1. T3 treatment increased organic matter digestibility by 3.06% compared to T1.Conclusions: It can be concluded that the crude protein and organic matter digestibility of sorghum fodder at 15 days harvest stage, increases with the addition of fermented cattle urine up to 25.0 ml/L hydroponic media.

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.

Enzymatic Methods

Rumen fluid and cellulase based techniques are widely used to predict the digestibility of compound feeds and their ingredients. Recently gammanase enzymes have been added to some cellulase based techniques (Dowman, 1993; De Boever et al., 1994). Few comparisons of these techniques have involved by-product concentrate ingredients. The objective of this experiment was to compare the ability of three techniques, in vitro rumen fluid (RF), pepsin cellulase gammanase (PCG), and neutral detergent cellulase gammanase (NCDG), to predict the in vivo organic matter digestibility (OMD) of concentrate ingredients.

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.

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35´N) in 19992001. The dry matter yield and leaf:stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibility of both whole plant samples and leaf and stem fractions were analysed. In primary growth, the most rapid increase of dry matter, 220240 kg ha-1 per day, was measured around the beginning of the heading stage. There was a very strong positive correlation between the proportion of stems and the amount of dry matter in the primary yield. The daily growth rate of the regrowth was less than half of that of the primary growth. The fastest decrease, 1 percentage unit per day, in crude protein content was measured at the pasture stage (45-leaf stage). During the entire sampling period, the average daily decline in crude protein content in the primary growth of timothy was 0.65 percentage units. The main cause for the rapid decline in crude protein content was the high proportion of stem matter and its low protein content. In the regrowth, during the last four weeks before the harvest, the average daily decline in crude protein content was 0.28 percentage units.The average decline in organic matter digestibility from early pasture stage to late silage stage was 0.9 percentage units per day. The most remarkable change was noticed at the growth stage of timothy when about the half of stems were heading and it was then that the digestibility decreased by more than one percentage unit per day. The rapid decline in organic matter digestibility was due to the low digestibility of stem matter. The daily change in forage digestibility in the regrowth was very small, on average 0.11%.;
