EVALUATION OF BIOLOGICAL VALUE OF DRY MATTER AND ORGANIC MATTER COMPLETE FEED BASED ON CORN FORAGE IN DAIRY COWS. This aim of this study was to determine intakes and digestibility of the dry matter and organic matter of complete feed based on corn forage. 14 FH cows weighing 300-400 kg were used in this research. The feed treatments consist of  Ra (30% concentrate + 70% corn forage), and  Rb (30% concentrate + 35% corn forage +    35% king grass). This experiment arranged in a statistical method of t-test two sample assuming unequal variance. The variables observed were intakes and digestibilities of both dry matter and organic. The results shows that the intakes of both dry matter and organic matter in the Ra were not significantly different from the Rb (P> 0.05). The dry matter digestibility of Rb were highly significant different from Ra (P<0.01), as well as organic matter digestibility of Rb was also significantly different from Ra (P <0.05). It is concluded that complete feed consisting of concentrate, corn forage and king grass was obtained the best digestibilities of both dry matter and organic matter.

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.

ABSTRACTOne hundred tonnes of spring-sown barley harvested as whole crop were treated on a commercial farm with pearl sodium hydroxide at 46 g/kg dry matter.The treated material was stored in a silage clamp beneath grass and lucerne silage. A thin layer of grass, cut and wilted to hay-making dry matter, was placed immediately on top of the barley to absorb any silage effluent.Monthly samples were taken for microbiological examination and chemical analysis throughout winter storage, while the material was fed to British Friesian dairy cows. There was no evidence of fermentation by clostridia in the whole-crop barley or wilted grass and there was no spoilage of the exposed feeding face. The treatment increased the in vitro organic matter digestibility and the in vitro digestible organic matter in the dry matter of the whole-crop barley. No excessive urination or other ill effects were observed in the stock.The method proved practical for the satisfactory storage and feeding of sodium hydroxide-treated whole-crop barley.

AbstractTwenty-eight Holstein/Friesian dairy cows were divided into four groups of seven. From weeks 4 to 15 of lactation they were given a basal diet consisting of 8 kg hay, 2 kg sugar-beet feed and 2 kg grass nuts, together with a concentrate allowance of 8 kg/day. Concentrates for group A were based on cereals and soya (control). Concentrate B contained 60 g protected fat supplement per kg; concentrate C contained 100 g lactose per kg; concentrate D contained 60 g fat supplement and 100 g lactose per kg. Milk yields were 24·6, 27·7, 25·6 and 26·5 kg/day and milk protein concentrations were 32·3, 30·7, 32·7 and 31·9 g/kg for groups A, B, C and D respectively. The effect of fat supplementation on milk yield and protein concentration was significant (P < 0·05) but the effect of lactose was not significant. Milk fat concentration was not significantly affected by treatment. It is concluded that lactose can partially alleviate the depression in milk protein concentration often observed when cows are given protected fat.

The general characteristics of a group of thirtynine herds of dairy cows in the Eastern Counties of England, and the method of obtaining information about their diet during the winters 1938–9 to 1942–3 inclusive, are briefly described.The first three winters of the war show a continuous decline in starch equivalent and protein equivalent per cow, followed by a recovery during winter 1942–3.Comparing winter 1942–3 with winter 1938–9: Consumption per cow of concentrates declined by one-third, reductions in proprietary compounds and mixtures and in maize and wheat products being outstanding.The more important increases were in oats, straw and succulent foods, notably mangolds, sugar-beet tops and kale.Hay retained its important place with little overall change; a modest increase in silage was restricted to a few herds.The crude weight of the average daily ration increased from 44 to 61 lb., but its dry matter only from 21·0 to 22·6 lb.The residue: total dry matter less digestible organic matter—increased from 7·2 to 8·4 lb. per cow daily. Reference is made to changes in palatability.

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 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.
