This study was conducted to study the effects of the intake of the Alysacrpus Monilifera on dry matter intake, digestibility of nutrients and performance of Desert bucks. Twelve Desert goats bucks 4-5 years old with an average weight of 11 + 0.250 kg, were divided into three equal groups. The first group was fed A. Monilifera fodder, while the second group consumed the natural pasture free of A. Monilifera while the third group consumed the groundnut haulms. After observing the cases of deadly diarrhea in the first group, the feeding pattern was modified with 50% natural pasture and 50% A. Monilifer fodder. The fodder was analyzed as well as conducting in vitro digestibility. The experimental design was randomized and the data were analyzed using the analysis of variance and the detection of differences among means using least significant difference test. The results showed that feeding A. Monilifer alone resulted in fatal diarrhea in bucks without affecting appetite, and the dry matter digestibility and organic matter in vitro digestibility was significantly (P<0.05) higher in A. Monilifer than compared to the groundnut haulms or the natural grazing. The weight gain was significantly (P<0.05) higher for the group on groundnut haulms and the natural grazing than those on A. Monilifer alone but when 50% of the plant biomass was replaced by the natural grazing the gain was significantly higher. The study concluded that the intake of A. Monilifer at the growth stage was good quality roughage when fed as part of the diet.

C3 Grasses

In a study that included C4 tropical grasses, C3 temperate grasses and C3 pasture legumes, in vitro dry matter digestibility of extrusa, measured as in vitro dry matter loss (IVDML) during incubation, compared with that of the forage consumed, was greater for grass extrusa but not for legume extrusa. The increase in digestibility was not caused by mastication or by the freezing of extrusa samples during storage but by the action of saliva. Comparable increases in IVDML were achieved merely by mixing bovine saliva with ground forage samples. Differences were greater than could be explained by increases due to completely digestible salivary DM. There was no significant difference between animals in relation to the saliva effect on IVDML and, except for some minor differences, similar saliva effects on IVDML were measured using either the pepsin–cellulase or rumen fluid–pepsin in vitro techniques. For both C4 and C3 grasses the magnitude of the differences were inversely related to IVDML of the feed and there was little or no difference between extrusa and feed at high digestibilities (>70%) whereas differences of more than 10 percentage units were measured on low quality grass forages. The data did not suggest that the extrusa or saliva effect on digestibility was different for C3 grasses than for C4 grasses but data on C3 grasses were limited to few species and to high digestibility samples. For legume forages there was no saliva effect when the pepsin–cellulase method was used but there was a small but significant positive effect using the rumen fluid–pepsin method. It was concluded that when samples of extrusa are analysed using in vitro techniques, predicted in vivo digestibility of the feed consumed will often be overestimated, especially for low quality grass diets. The implications of overestimating in vivo digestibility and suggestions for overcoming such errors are discussed.

Protein source feed is the feed that has the biggest share in the nutritional needs of livestock. Lamtoro or Leucaena leucocephala is one of the leaf flours that can be used as an alternative feed ingredient for poultry in the tropics. With its abundant availability and does not compete for its needs with humans and has no selling value so that it can minimize consumption costs for poultry. This study aims to determine the effect of fluid from the digestive tract of chickens on the in vitro digestibility measurement of lamtoro leaves. The study used a completely randomized design (CRD) with a unidirectional pattern with 4 treatments and 3 replications. The treatments consisted of P0 = control, P1 = gizzard fluid, P2 = duodenal fluid and P3 = a mixture of gizzard and duodenal fluid. The results of this study show the average Dry Matter Digestibility Coefficient (%) for the treatment P0, P1, P2 and P3 respectively; 19.276, 29.089, 20.515 and 28.737. Organic Matter Digestibility Coefficient ; 27.702, 36.313, 24.795 and 35.649. Dissolved Protein Digestibility Coefficient ; 39.777, 53.288, 21.145 and 48.737. The results of the statistical test that the administration of lamtoro leaves showed a significant difference (P<0.05) on the digestibility coefficient of dry matter, organic matter and dissolved protein. The conclusion is that the use of gizzard liquid is more effective in increasing the in vitro digestibility of lamtoro leaves.

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.

A comparison of two near infrared (NIRA) calibrations (C1 and C2) for the prediction of in vitro dry matter digestibility (IVDM) in whole-plant corn (WPC) was conducted. C1 consisted of 40 WPC samples collected from four locations across Ontario (Brucefield, London, Guelph and Elora). C2 consisted of 90 samples and included the above locations plus Pakenham and Winchester. Nine wavelengths were used in both equations but only three were common in C1 and C2 equations. These wavelengths were 2139 nm, 2100 nm, and 1445 nm, respectively. The predictions of IVDM utilizing both C1 and C2 were good. Coefficients of determination (r2) and standard error of the estimate (SEE) for calibration and prediction sets were 0.91, 1.7; 0.85, 1.7 for C1 and 0.88, 1.6; 0.77, 1.6 for C2 respectively. Regression analysis within location, however, showed low r2 values for the prediction of IVDM for Pakenham and Winchester in both calibrations. The more mature stage of harvest at these locations might be the cause of the poorer predictions. Key words: In vitro digestibility, whole-plant corn, near infrared reflectance

The in vitro dry matter digestibility (I.V.D.) of the stem and total leaf fractions of four orchardgrass clones was similar at the preheading stage. Even at 100% head emergence, differences in I.V.D. between stems and living leaves were not great with the early-maturing clones. However, wide differences existed between the values for stems and living leaves in mature plants. Heads were only slightly higher than stems in digestibility.Leaf digestibility was lower for those leaves dead or even partially dead. Nevertheless, in mature plants, dead leaves were higher in I.V.D. than heads or stems. Large differences occurred among clones in stem digestibility. However, the variability among clones in leaf digestibility was small.

Dry Matter Digestibility

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

The microbial protein bioconversion of cactus pear by yeast in solid medium was studied. Three cultivation variables used were: inoculum's concentrations (5, 10 and 15 %), substrate layer thickness (2, 4 and 6 cm) and temperature (30, 34 and 38 ºC). The rate of dry matter production and total protein were determined. Results obtained were variance analysis, gross energy and in vitro dry matter digestibility. The maximum protein amount achieved for the conditions studied in the present work was higher than 26 %, which was compatible or greater than those of conventional concentrates of protein supplements used for animal feed. The protein concentrate of cactus pear had a higher in vitro digestibility index (95.8 %) and did not show any changes in the gross energy value when compared to that of the cactus pear in natura.

In the semi-arid tropics, accumulated shed leaf of certain pasture legumes can provide highly nutritious feed for cattle in the dry season. Previous papers in this series have dealt with the fungal spoilage of leaf of Caribbean stylo in response to dew and unseasonal rainfall and the threat to acceptability by cattle. This paper focuses on the effects of varying degrees of moulding and leaching on dry matter digestibility of leaf of this legume. Uniform leaf material of high digestibility was exposed at six locations during the dry season and samples retrieved at 4-weekly intervals. From initial values of 75%. in vitro digestibility dropped to as low as 50%. Degree of moulding, as indicated by a quantitative index of discoloration, accounted for about 80�/o of loss. Moulding was much more important than leaching. This latter finding in the winter-dry tropics contrasts with previous findings in the summer-dry Mediterranean climate.

A series of experiments has been carried out with tannin-free and tannin-containing cultivars of fababeans. The in vitro dry matter digestibility of the cotyledon portion of the two groups of fababeans was the same (88.2%) whereas the in vitro digestibility of the testa portion of the tannin-free cultivars was much higher (27.6%) than that of the tannin-containing cultivars (9.2%). The concentrations of certain cell wall constituents in the testae of tannin-free and tannin-containing cultivars were also different (P < 0.01); the respective average values for the two groups were: condensed tannins, 0.2 and 4.9%; lignin, 4.2 and 6.2%; acid detergent fiber, 72 and 66%; and cellulose, 67 and 60%. There was a negative correlation between the in vitro dry matter digestibility and the amount per unit weight of whole beans of either condensed tannin (r = −0.86, P < 0.01) or lignin (r = −0.89, P < 0.01). When expressed on a similar basis there was no correlation between levels of cellulose or acid detergent fiber and in vitro dry matter digestibility.
