Corn stover stacks were harvested and a portion of these were treated with anhydrous ammonia at a level of 3% of dry matter (DM) and left covered with plastic for at least 30 days during the fall of 1977. In the spring, both treated and untreated corn were chopped through a forage harvester. A portion of each was then ground through a 1.3-cm screen. Treatments were: untreated chopped, untreated ground, ammoniated chopped, ammoniated ground. Treatments were evaluated with eight Hereford-Angus yearling steers in a double 4 × 4 latin square design. In addition to the stover, rations contained 10% molasses, 6% soybean meal, and 2.3% mineral mix. Urea was added to the untreated rations at the level of 1.6% to make rations isonitrogenous. Steers were injected with vitamins A, D and E at 90-day intervals. With both control and ammoniated rations, grinding increased (P < 0.001) intake on a body weight raised to the 0.75 power basis (MBW) of DM, digestible energy (DE) and digestible DM by 47%, 39%) and 39%), respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) intake of digestible DM and DE and increased (P < 0.01) intake of DM all on a MBW basis by 22%, 31% and 12%), respectively. However, grinding decreased digestibilities of DM and neutral detergent fibre (NDF) (P < 0.001) and of organic matter (OM) (P < 0.01) by 5%, 10% and 5%, respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) digestibility of DM, OM, and NDF by 9%, 9% and 14%, respectively. Ammoniation plus grinding increased (P < 0.01) intake (MBW) of DM, digestible DM and DE by 64%), 71% and 85%), respectively, over untreated chopped rations. Grinding increased (P < 0.01) rumen acetate 0.5 h preprandially but did not significantly affect other rumen parameters measured preprandially or 2 h postprandially. Ammoniation increased (P < 0.01) rumen propionate 0.5 h preprandially but did not significantly affect the remaining rumen parameters. Before versus after feeding levels of rumen metabolites did not differ except for an increase (P < 0.01) in ammonia-N and total VFA postprandially. No significant treatment interactions were present.

THE EFFECTS OF OFFERING KING GRASS (Pennisetum purpupoides) AND CORN  STOVER ON DRY MATTER AND  ORGANIC MATTER OF ONGOLE CROSS BREED STEER CALVES. A research has been conducted to evaluate the effects of offering king grass (Pennisetum purpupoides) and corn stover as ingredients for ration formulating on dry matter and organic matter digestibility of ongole cross breed steer calves. Five ongole cross breed steer calves with about 100 kg body weight were used in this experiment. Latin square design  with 5 tereatments was used. The treatments were rasio of king grass and corn stover; R1 = 100% king grass, R2 = 75% king grass + 25% corn stover, R3 = 50% king grass + 50% corn stover, R4 = 25% king grass + 75% corn stover, R5 100% corn stover.  The variables measured were dry matter and organic matter digestibility. Analysis of variance showed that there were no significant effect of treatments on dry metter and organic matter digestibility. Averages of dry matter digestibility during experiment ranged 56.27% - 59.48%. The highest was 59.48% for R5 (100% corn stover) and the lowest was 56.27% for R1 (100% king grass). Averages of organic matter ranged from 87.64% to 88.72%. The highest organic matter digestibility was on R4 (25% king grass + 75% corn stover) and the lowest organic matter digestibility was on R2 (75% king grass + 25% corn stover). It can be concluded that the best nutritive value was at combination of 25% king grass + 75% corn stover on dry matter and organic matter digestibility of ongole cross breed steer calves. keywords: king grass, corn stover, digestibility, dry matter, organic matter

A research evaluating dry matter (DM) and organic matter (OM) digestibility of crops residues and local grass supplemented urea molasses multinutrient block (UMMB) on Ongole crossbred cattle (PO). Four male PO cattle, 12 – 18 months of age with ± 100 kg of body weight were used in this experiment. Latin Square Design 4 x 4 with 4 cows and 4 treatments was used. The treatments were : R1 : UMMB + local grass, R2: UMMB + Corn straw, R3: UMMB + Rice straw, and R4: UMMB + peanut straw. The results showed that there were significant effect (P<0.01) of treatments on NDF and ADF digestibility. C1 showed that NDF and ADF digestibility of local grass (68.44% and 61.37%) were higher (P<0.05) compared to crop residues (corn straw 65.25% and 58.59%, rice straw 62.63% dan 52.80%, and peanut straw 67.53% and 59.81%) respectively. C2 showed that NDF and ADF digestibility of legume straw was higher than grasses straw; and C3 showed that  NDF and ADF digestibility of rice straw was lower than corn straw. The results have concluded that : 1. NDF and ADF digestibility of local grass were higher compared to crop residues. 2. NDF and ADF digestibility of legume straw (peanut straw) was higher than grasses straw  (corn straw and ricce straw);3. NDF and ADF digestibility of  corn straw was higher than peanut straw.Key words: NDF and ADF digestibility, crop residues, UMMB, ongole crossbred cattle

Abstract Two experiments were conducted to investigate the effects of phytase source and feed pelleting on digestibility of dry matter (DM), crude protein, organic matter (OM), and phosphorus (P) with different doses of phytase in pigs. In Exp. 1, ten barrows (31.4 ± 3.5 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 6 Latin square design with 5 diets and 6 periods. In Exp. 2, ten barrows (28.2 ± 3.2 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 5 Latin square design with 5 diets and 5 periods. Each period lasted 10 d consisted of a 5-d adaptation and a 5-d collection periods and the marker to marker method was used for fecal collection. In both experiments, a basal diet was prepared based on corn and soybean meal without phytase or inorganic P. Four additional diets were prepared in a 2 × 2 factorial treatment arrangement with 2 phytase sources (Buttiauxella spp. or Escherichia coli) and 2 feed forms (mash or pellet). Both experiments employed the same treatments but had different supplemental phytase doses (500 and 1,500 FTU/kg in Exp. 1 and 2, respectively). In Exp. 1, supplemental phytase increased standardized total tract digestibility of P (66.1 vs. 51.7%; P &lt; 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM, crude protein, and OM (P &lt; 0.001). In Exp. 2, supplemental phytase increased standardized total tract digestibility of P (72.8 vs. 44.8%; P &lt; 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM and OM (P &lt; 0.001). Taken together, supplemental phytase at 500 and 1,500 FTU/kg increases P digestibility regardless of phytase source or feed pelleting.

Alfalfa Meal

Eight sheep were used in two 4 × 4 latin square digestion trials substituting alfalfa meal with unsteamed or steamed muka (foliage) at levels of 20, 40 or 60%. Including muka at all levels depressed (P < 0.05) the digestibility of dry matter, organic matter, crude protein and acid detergent fiber compared with the control alfalfa meal diet. When calculated by difference, the digestibility of muka dry matter and organic matter was not affected (P < 0.05) by either the level of its inclusion in the diets or by steaming. The mean dry matter and organic matter digestibilities of muka were 29.2 and 30.4%, respectively. The protein content of muka was 5.0% and the estimated protein digestibility at the 60% level of inclusion was only 6.6%. With unsteamed muka, the digestibility of acid detergent fiber calculated by difference averaged −11.9%, suggesting the presence of factors which depressed the digestibility of fiber in the basal diet. Steaming appeared to reduce this depression. A growth trial was conducted with lambs where alfalfa meal, as the sole roughage source, was compared to the same diet with 20% of the alfalfa replaced by steamed muka. Growth rates were not different (P > 0.05) being 142 and 138 g/day, respectively. A taste panel evaluation of the carcasses found no adverse effects on flavor due to the inclusion of steamed muka in the diet. Key words: Lodgepole pine muka, nutritive value, sheep

Abstract The obstacles of using supplementation are related to the cost and labor. Self-fed supplements of low and medium intake can be an option to overcome these problems. However, the nutritive value and pasture yield are crucial to finding the right composition and amount of supplement. We evaluated productive responses of steers receiving self-fed supplements of low and medium intake on Aruana grass pasture. The animal performance, ingestive behavior, and pasture characteristics were evaluated in a completely randomized design with three treatments and three replicates. Twenty-four Aberdeen Angus steers were used as the tester animals. The dry matter intake and nutrient digestibility were evaluated in a 3 x 3 double Latin square repeated over time. The treatments consisted of mineral salt (control), supplementation for intake of 1.5 g/kg body weight (low-intake), and supplementation for intake of 4.0 g/kg body weight (medium-intake). The supplements did not influence the pasture characteristics and ingestive behavior, except the number of bites/day that was higher for the low-intake. Dry matter digestibility and forage intake were not affected by the supplementation, but the total dry matter intake increased for the medium-intake. The average daily gain, stocking rate, and fat thickness gain were higher for the medium-intake. The self-fed supplements of medium-intake increase the total dry matter intake, maximizing the performance of steers on Aruana grass.

Four castrated crossbred (Karagouniki♂ × Friesian♀) rams were used in a 4 × 4 Latin-square design to determine the apparent digestibility of four diets based on alfalfa hay and maize grain and containing varying proportions of whole cottonseed (WCS). The proportions of WCS studied were 0, 175, 355 and 530 g/kg diet dry matter (DM) and the respective apparent digestibility coefficients of DM were 0·744, 0·716, 0·689 and 0·625; of organic matter, 0·772, 0·739, 0·718 and 0·643; and of neutral-detergent fibre (NDF), 0·409, 0·481, 0·522 and 0·472. The gross energy (GE) apparent digestibility coefficients were 0·745, 0·722, 0·704 and 0·641, for the same order of treatments. The effect of the incorporation of WCS instead of maize grain in the diet in significantly reducing DM, OM and GE digestibility was evident. The lowest digestible energy value of WCS was observed in the treatment with the highest level of WCS.

The objective of this study was to evaluate the effect of varying levels of cassava leaf pellet (CLP) on feed intake, digestibility and rumen fermentation of goats fed with pangola hay as roughages. Eight growing crossed (Thai native x Anglo-Nubian) goats between 10 to 12 months of age and pre-trial average body weight of 18.5 + 2.5 kg were allotted into two groups on the basis of body weight in a randomized double 4 x 4 Latin square design to investigate the utilization of concentrate mixtures of varying levels of CLP. The four concentrate mixtures had CLP included at 0% (control), 10 % (CLP1), 20% (CLP2) and 30% (CLP3) in concentrate as replacing soybean meal (SBM) with CLP as 25 %CP, 50%CP and 75%CP, respectively.  On average, all parameters measured, including dry matter intake (DMI), nutrients digestibility, ruminal ammonia-N (NH3-N), ruminal total volatile fatty acid (total VFA), individual VFAs concentration (mM/L), microbial N supply, and N retention increased (P less than 0.05) with the addition of CLP in concentrate up to 20% (CLP2) in concentrate, thereafter  decreased (P less than 0.05) in goats fed CLP 30% (CLP3). The results indicated that replacing SBM with CLP as 50 %CP (CLP2), resulted in higher animal performance as a consequence of improved ruminal fermentation, microbial yield and N balance,  but decreased (P less than 0.05) with 30% CLP diet. It is concluded that cassava leaf pellet can successfully replace soybean meal 50% CP as a protein source in growing goats.

Concentrate Treatment

SUMMARYA 6 x 6 Latin Square balance experiment was carried out using six Friesian steers, each of which initially weighed about 304 kg. The six treatments studied were an all-hay diet and five other diets containing 20,40,60,80 and 100 % of rolled barley fortified with mineral and vitamin supplements, accompanied by correspondingly reduced proportions of hay. Each diet was fed at an estimated maintenance level of feeding.The progressive increase in the proportion of concentrate gave a significantly linear increase (P < 0·001) in both digestible and calculated metabolizable energy. The actual increase in digestible energy was from 2·62Mcal/kg dry matter (59·3% of the gross energy) on the all-hay treatment to 3·42 Mcal/kg dry matter (79·5% of the gross energy) on the all-concentrate treatment. Use of the determined digestible energy values for the all-hay and fortified barley diets to calculate the digestible energy of the four mixed diets gave results in reasonably good agreement with the determined values, the maximum difference being 0·12 Mcal/kg dry matter, which represented 3·83 % of the determined value. The losses of energy in the urine expressed as percentages of the gross energy of the diets showed a small but significantly linear decrease (P < 0·01) with increase in proportion of barley in the diet. The molar proportions of steamvolatile acids in samples of rumen fluid taken from two animals on each treatment indicated that increase in the proportion of concentrate was associated with tendencies for increase in acetic acid, decrease in propionic acid and little change in butyric acid. The mean digestibility of the organic matter was 62·6 % on the all-hay treatment and 81·8 % on the all concentrate treatment. The progressive increase in the proportion of concentrate gave a significantly linear increase (P < 0·001) in digestibility of the organic matter. Although intakes of nitrogen decreased with increase in the proportion of concentrate due to a decrease in the amount of dry matter fed, the weights of nitrogen retained were well maintained and when expressed as percentages of intake showed a significantly linear increase (P < 0·01).

SUMMARY It was evaluated the effect of feed supplementation at 0.4; 0.8 and 1.2% of body weight (BW) on intake and digestibility of crossbred goats finished on caatinga, in relation to crossbred goats not supplemented (0.0% of BW). Thirty-two crossbred, Anglo-Nubian goats were used, eight months old and with body weight of 18 ± 2.5 kg, organised into randomised blocks, which were kept on 37 hectares of caatinga from 7 h to 16 h. Intake of dry matter, organic matter, crude protein, ether extract, neutral and acid detergent fibre, total carbohydrates and total digestible nutrients was influenced (P<0.05) by the levels of feed supplementation, with linear increases of 202.31; 179.42; 25.05; 11.83; 35.79; 12.27; 142.63 and 166.79 g animal-1 day-1 respectively. There was a substitution effect (P<0.05) on dry matter intake when using feed supplementation at 0.7% BW. Feed supplementation resulted in positive linear effect (P<0.05) for digestibility of dry matter, organic matter, crude protein, ether extract, total carbohydrates, total digestible-nutrient content and digestible energy, with an increase of 17.15; 16.64; 19.07; 44.74; 15.15 and 17.56% for dry matter, and 0.69 Mcal kg-1 of dry matter respectively. Final body weight, total gain and average daily gain, showed a linear increase (P<.005) of 2.60, 3.09 and 0.036 kg per percentage point of each additional level of supplement. Feed supplementation increases the intake and digestibility of total dry matter and nutrients, a fact that makes greater performance possible, and recommends use up to a level of 0.7% BW to avoid any substitution effect.

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%.;
