In an experiment of 3 x 3 Latin Square design, 3 heifers each fitted with rumen and simple T-piece duodenal cannulae were used to determine the effects of method of processing soyabean meal (SBM), and low (LRSM) and high (HRSM) glucosinolate rapeseed meals on rumen degradabilities (RD) and intestinal digestibilities of dry matter (DM), nitrogen (N) and organic matter (0M) using a mobile nylon bag technique.Heifers were given a basal diet of hay (0.55 of DM intake) and mineralized barley with LRSM (0.45 of DM intake) to provide a ME intake of > 2 x maintenance. The diet was offered twice a day and a period of four weeks was allowed before the experiment. Methods of processing were formaldehyde (FT, 0.8 HCH0/l6g N), heat (HT, 110°C for 2 h) and untreated (UT). After processing the feedstuffs were ground and 1g samples were placed in sealed nylon bags (3-5 x 5.5 cm). The bags were placed in a plastic mesh cylinder and incubated in the rumen for 0, 12, and 24 hours.

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 < 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM, crude protein, and OM (P < 0.001). In Exp. 2, supplemental phytase increased standardized total tract digestibility of P (72.8 vs. 44.8%; P < 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM and OM (P < 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

Soyabean Meal

The effects of methods of processing soyabean meal (SBM), and low (LRSM) and high (HRSM) gluco-sinolate rapeseed meals on rumen degradability (DG) of dry matter (DM) and nitrogen (N), were determined by the nylon bag method in experiments of Latin Square design with 4 rumen-fistulated heifers. Rumen fractional outflow rates (FOR) for untreated SBM, LRSM and HRSM were determined by the chromium-mordant method in 2 heifers. Effective rumen degradabilities (EDG) for rumen incubation times of 24 h were calculated from DG and FOR.Methods of processing were formaldehyde (FT, 0.8g HCH0/I6g N), heat (HT, 110°C for 2 h) and untreated (UT). Heifers were given a basal diet of hay (0.55 of DM intake) and mineralized barley with LRSM (0.45 of DM intake). The diet was offered twice a day at 08.00 and 16.00 hours. An adaptation period of four weeks preceded the experiments.

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).

NDF AND ADF DIGESTIBILITY WHICH GET THE SUPPLEMENTED UREA MOLASSES MULTINUTRIENT BLOCK (UMMB) OF SOME CROP RESIDUES TYPE AND LOCAL GRASS ON ONGOLE CROSSBRED CATTLE. 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

Earlier studies with temporarily isolated rumen of heifers show saturation kinetics of Mg efflux across the rumen wall. Therefore, we hypothesized that high Mg intakes would not further increase the rate of Mg absorption in cows. To test our hypothesis, six ruminally fistulated non-pregnant dry cows were given diets with different Mg concentrations in a 6×6 Latin square design. Desired concentrations of Mg were attained by adding MgO to the basal diet and the Mg concentrations in the total rations were 3·8, 6·4, 9·1, 11·8, 14·1 and 17·3 g Mg/kg dry matter, which provided Mg intakes of 27·1, 44·6, 64·6, 83·5, 100·4 and 124·3 g/d, respectively. Increasing Mg intakes were associated with increased (P<0·001) faecal Mg excretion. However, apparent Mg absorption expressed as g/d was not significantly different for Mg intakes from 100·4 to 124·3 g/d while Mg absorption expressed as a proportion of intake was not significantly different for Mg intakes ranging from 64·6 to 124·3 g/d. Mg concentrations in rumen fluid after feeding increased (P<0·001) with increasing Mg intakes. Apparent absorption of Mg appeared to become saturated at a ruminal Mg concentration of 17·5 mM (Mg intake of 83·5 g/d). Group-mean post-feeding concentrations of Mg and Na in rumen fluid were significantly correlated (Pearson's r=−0·96; P=0·003, n=6). This study showed that under conditions of practical dairy cow feeding, Mg absorption was maximal at Mg intakes [ges ]84 g/d.

Feedblocks, poultry manure diet, gliricidia: leucaena mixture (1:1 W/W) and maize offal diet were compared as sources of protein supplements for WAD sheep fed a basal diet of elephant grass hay (Pennisetum purpureum), through a 12-week performance and digestibility study. Dry matter and organic matter intakes (DMI, OMI) of the sheep were higher (P0.05) on the gliricidia: leucaena supplement than on the other diets. DMI on poultry manure and maize offal diets were not significant (P0.05). Organic matter intake (OMI) of the animals followed the same trend as DMI. Sheep fed legume supplements excelled in intakes of crude protein (CP), acid detergent fibre (ADF) and digestibilities of dry matter (DM), organic matter (OM) and neutral detergent fibre (NDF) (P>0.05). Intakes of CP and ADF by sheep on the other supplements were not significantly different (P>0.05). Sheep fed on feedblock supplement consumed the least amount. (P0.05) of NDF. Variations were observed in DM,OM, and NDF digestibilities by sheep on maize offal, poultry manure and legumes supplements. Crude protein digestibility in the legumes and feedblocks supplements was higher (P0.05) than with the other two supplements. All the sheep used gained weights but those on maize offa' diet recorded higher (P0.05). weight gain (86.57g) than those on browse leaves (59.40g), feedblocks (47.80g) and poultry manure (40.44g). Rumen pH was lower (P<0.05) on the gliricidia: leucaena supplement than on other diets. Total VFA recorded for sheep on maize offal diet and legumes supplements was higher (P<0.05) than for the other two supplements. Blood urea nitrogen of the supplements were not significantly different (P>0.05)

Design Experiments

Rumen-fistulated yearling steers were used in two 4 × 4 latin square design experiments to determine the digestibility and nitrogen retention of all-concentrate rations with various supplements. The inclusion of 5.7 per cent sodium bicarbonate in either a ground- or dry-rolled-grain ration resulted in an increase in urine excretion. Digestibility of organic matter and nitrogen or nitrogen retention were not affected. The addition of 60 milliliters of cod liver oil (1200 I.U. vitamin A, 150 I.U. vitamin D per gram) per day to the bicarbonate supplemented, ground-grain ration tended to decrease organic matter digestibility while the addition of 3.6 per cent sodium propionate tended to increase organic matter digestibility. Differences between these rations and the bicarbonate ration were not statistically significant; however, the percentage of nitrogen retained on the cod liver oil supplemented ration was significantly (P < 0.05) lower than on the propionate supplemented ration.The inclusion of 5.7 per cent ground limestone significantly (P < 0.05) reduced the digestibility of dry matter, and nitrogen, but the digestibility of organic matter was not significantly lower at this probability level.
