Summary. The effect of continuous grazing on pasture composition and quality was assessed on 2 pasture types in a subtropical environment. The pastures were native stocked at 1 cow/2.5 ha, and previously improved stocked at 1 cow/1.6 ha. In August 1990, carpet grass (Axonopus affinus) was the major species in both the native (49.8%) and improved (61.3%) pastures. However, the proportion of carpet grass decreased during the study to 33% in the native pasture and 30% in the improved pasture in February 1994. In the native pasture, blady grass (Imperata cylindrica) increased at the expense of carpet grass, whereas in the improved pasture higher quality grasses, and to a lesser extent Giant Parramatta grass (Sporobolus indicus), increased at the expense of carpet grass. Overall, dry matter on offer and green dry matter depended on rainfall and these peaked in late summer. Dry matter on offer differed between non-drought and drought periods in both pastures and was ≤3500 kg/ha in drought months in the native pasture and ≥3500 kg/ha in comparable months in the improved pasture. Green dry matter was higher in pastures towards the end of the summer growing season (83%, March 1992) and lower during many of the drought months (12%, May 1991). Grazing pressure (liveweight 0.75/t green dry matter) was highest in August, the crucial period for weed incursion. Organic matter digestibility was highest following rain in late spring (November 1990; 69%, improved pasture) but lowest in the absence of rain (November 1993; 38%, native pasture). The proportion of green dry matter in the native pasture was not related to organic matter digestibility nor to the nitrogen content of plucked pasture samples. However, in the improved pasture the proportion of green dry matter was related to organic matter digestibility on 3 occasions but not to nitrogen content.

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 1999–2001. 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, 220–240 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 (4–5-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%.;

The experiment goal was to determine the supplementation effect of katuk leaves meal and Zn bio complex on dry and organic matter consumption and digestibility of postweaning male of Ettawa Crossbred. The experiment used sixteen heads of the postweaning male of Ettawa Crossbred aged 4-5 months with an initial body weight of 9.01±1.85kg (CV 20.55%). Completely Block Randomized Design (CBRD) with 4 treatments and 4 replications were applied in this experiment. Those treatments were P0: Lamtoro + concentrate without katuk leaves meal and Zn biocomplex (control); P1: P0 + 5% katuk leaves meal (on the basis of forage dry matter)  and Zn bio complex; P2: P0 + 10% katuk leaves meal (on the basis of forrage dry matter) and Zn bio complex; P3: P0 + 15% katuk leaves meal (on the basis of forage dry matter) and Zn bio complex. Variables measured were dry matter (DM) consumption, organic matter (OM) consumption, DM digestibility, and OM digestibility. Average of DM  consumption were P0 (326.68 ±44.13g/h/d), P1 (351.68±63.47g/h/d), P2 (351.78±33.41g/h/d) and P3 (346.24±32.48g/h/d). Average of OM consumption were, P0 (300.38 ±41.14g/h/d), P1 (316.11±57.05g/h/d), P2 (315.54±30.83g/h/d) and P3 (309.21±29.00g/h/d). Average of DM digestibility, P0 (78.94 ±4.67%), P1 (78.77±9.54%), P2 (64.82±11.45%), P3 (75.38±14.56%). Average of OM digestibility, P0 (81.17±4.01%), P1 (80.77±8.69%), P2 (68.79±9.90%), and P3 (76.93±12.77%). The result of variance analysis showed that treatment has a significant effect (P<0.05) on dry and organic matter consumption but no significant (P>0.05) on dry and organic matter digestibility It can be concluded that supplementation of of katuk leaf meal (Sauropus androgynus L. Merr) at 5% up to 15% and Zn bio complex might increase dry and organic matter consumption of postweaning male of Ettawa crossbred.

Grass silage forms the basal forage for the majority of dairy and beef cattle during the winter indoor feeding period. However its feeding value, as determined by intake potential and digestibility can differ dramatically at farm level as indicated by the Hillsborough Feeding Information System (HFIS). For example, for 7000 silages which were offered to dairy and beef cattle during the 1999/2000 indoor feeding period in Ireland and analysed through the HFIS, dry matter digestibility (DMD) varied from 540 to 830 g/kg DM (Keady, 2000). Many models used to predict feed intake by dairy cattle include a digestibility component (Keady and Mayne, 2000). However some models use DMD whereas others use digestible organic matter digestibility (DOMD). Furthermore commercial laboratories in Ireland measure silage digestibility as DMD while in the UK it is measured as DOMD. To facilitate the use of different models to predict food intake by dairy cattle, often it is necessary to be able to predict DMD from DOMD or vice versa. The present study was undertaken to develop a relationship between DMD and DOMD to facilitate the use of different models for the prediction of food intake when digestibility is available only either as DMD or as DOMD.

Aim: This research aimed to discover the chemical composition, as well as the content of the degradable and undegradable protein of the ruminant feed commonly used as cattle feed by Indonesian farmers. Materials and Methods: In this study, Pennisetum purpureum, Leucaena leucocephala, Indigofera zollingeriana, Gliricidia sepium, cassava, maize, palm kernel cake, and rice bran were used as feed. Chemical composition was determined by proximate and Van Soest analyses performed in triplicate. Dry matter and organic matter digestibility, as well as the rumen degradable proteins (RDP) and rumen undegradable proteins (RUP) contents, were determined in vitro using the Tilley and Terry method. Results: The results showed that more proteins can be obtained from legumes than from grass or concentrates. The highest protein amount was obtained from I. zollingerian (31.22%), while the lowest protein amount was obtained from cassava (3.59%). Dry matter digestibility ranged from 18.53% (rice bran) to 49.21% (G. sepium). Organic matter digestibility ranged from 35.71% (cassava) to 59.57% (I. zollingerian). Rice bran had the highest RDP from concentrate (73.26%), whereas I. zollingerian had the highest RDP from forage (74.72%). The highest RUP from concentrate was obtained from palm kernel cake (61.01%), and the highest RUP from forage was obtained from L. leucocephala (49.23%). Conclusion: The preparation of ruminant livestock rations must be based on RDP and RUP to meet the needs of both the rumen microbes and host animals. Information regarding the RDP and RUP of feeds is still limited, making this study useful in the preparation of ruminant livestock rations based on RDP and RUP ratios. Keywords: chemical compositions, rumen degradable proteins, rumen undegradable proteins, ruminant, tropical feedstuff.
