The aim of the present study was to evaluate the effect of including different levels of peanut (Arachis pintoi cv. Amarillo) hay (167 and 572 g/kg dry matter (DM) of crude protein and neutral detergent fibre respectively) on the nutritional value of diets based on dwarf elephantgrass (Pennisetum purpureum Shum, cv. Kurumi) hay (98 and 668 g/kg DM of crude protein and neutral detergent fibre respectively). Peanut hay was included in the proportions of 0.0, 0.33, 0.66 and 1.00 of total diet DM. Eight Texel × Suffolk crossbred wethers provided with duodenal cannula were assigned to the treatments in a replicated 4 × 4 Latin-square experiment. The organic matter (OM) intake increased linearly (P < 0.05) and the total apparent OM digestibility decreased linearly (P < 0.001) with an increasing inclusion of legume. The nitrogen (N) intake and N urinary excretion increased linearly (P < 0.05), whereas linear and quadratic responses were significant for digestible OM intake, N retention, and for the efficiency of rumen microbial protein synthesis. Cubic positive responses were significant (P < 0.05) for duodenal flow of total N, non-ammonia-N and rumen microbial-N. The inclusion of A. pintoi in dwarf elephantgrass-based diets improved the nutrient supply to sheep, but no additive effect was observed as a result of increasing the peanut proportion in the mixed diet.

A duplicated 4 x 4 Latin Square experiment was conducted to determine the effects of a gradually increased level of barley fibre in the diet on ad libitum grass silage intake and milk production. Barley fibre is a fibrous ethanol-starch by-product (120 g crude protein, 550 g neutral detergent fibre (NDF) and 120 g starch/kg dry matter (DM)). The four supplements, given at the rate of 6.5 kg/d on DM basis, were barley (B) and barley of which 333 g/kg (BF), 667 g/kg (FB) and 1000 g/kg (F) were replaced by barley fibre. In addition the cows were given 1 kg of rapeseed meal and 0.25 kg of mineral mixture. As the proportion of barley fibre in the diet increased there was a linear (P

The objective of this study was to evaluate the inclusion rate of pea hay in barley or oat hay diets for beef cattle. Six ruminally cannulated heifers (407 ± 38 kg) were used in a 6 × 6 Latin square (25 d periods) with a 2 × 3 factorial design. Treatments included whole-crop barley or oat hay with pea hay blended in to achieve inclusion rates of 0%, 15%, or 30% (dry matter basis) of the forage. Pea hay inclusion increased dry matter intake (DMI; P = 0.03) by 0.75 kg d−1 relative to diets without pea hay, but the response was not linear or quadratic. Inclusion of pea hay linearly increased mean ruminal pH (P = 0.039), the concentration of butyrate in ruminal fluid (P = 0.013), plasma urea nitrogen (N) concentration (P = 0.001), and quadratically increased ruminal ammonia concentration (P < 0.001). Pea hay inclusion reduced crude protein (CP) digestibility by 2.87% relative to cereal-only treatments (P = 0.025), but did not affect N intake, microbial N, or N excretion. Overall, pea hay inclusion increased DMI, increased ruminal butyrate concentration, but reduced CP digestibility without affecting N balance.

Four mature wether sheep weighing 45–50 kg and fistulated in the abomasum and in the terminal ileum with plastic cannulas were used to determine the effect of formaldehyde treatment of rapeseed meal on the digestibility of nutrients and flow of nitrogenous compounds through the gastrointestinal tract. The sheep were fed four pelleted diets containing 8 or 16% rapeseed meal treated with water or formaldehyde at 1 g formaldehyde/100 g crude protein in a 4 × 4 latin square design. Urea was added to the diets containing 8% rapeseed meal at a level calculated to make all diets isonitrogenous; however, the actual N level of the formaldehyde-treated 8% rapeseed meal diet was somewhat higher than for the other diets. The animals were offered 600 g of feed twice daily at 12-h intervals. Formaldehyde treatment of rapeseed meal did not significantly affect the apparent digestibility of crude protein or dry matter of the experimental diets. No significant differences were observed in total N excretion, or N retention among the four treatments. However, N retained, expressed as grams or as a percentage of absorbed N, for the diets containing formaldehyde-treated rapeseed meal tended to be higher than for the diets containing water-treated rapeseed meal. Formaldehyde treatment of the 16% rapeseed meal diets moderated the increases in rumen fluid ammonia and blood urea N levels following feeding. Formaldehyde treatment of the 16% rapeseed meal diet also increased the flow of dry matter, total N (P < 0.01), and true protein N (P < 0.05) in the abomasal digesta of sheep compared to those fed the water-treated rapeseed meal diet. A similar, but nonsignificant (P > 0.05), effect of the formaldehyde treatment was observed in the ileal digesta of the sheep.

The objective of the present study was to evaluate the nutritional value of elephant grass (Pennisetum purpureum, Schum.) silages with the addition of 0; 4; 8; 12 and 16% of the by-product from SPU annato (Bixa orellana, L.) based on natural matter. A complete random design was used with four replications. The nutritional composition, pH, ammonical nitrogen and lactic, acetic, propyonic and butyric acids were determined. Levels of annato by-product had an increasingly linear effect on contents of dry matter, organic matter, crude protein, ether extract, non-fibrous carbohydrates, propionic acid and ammonical nitrogen. The insoluble nitrogen contents in detergent and acid detergent, calculated on the percentage of total nitrogen and lactic, acetic and butyric acids were not altered by adding the annato by product. The annatto by-product improves the bromatological characteristics of the silages and it can be added in levels up to 16% of the natural matter at the moment of elephant grass ensilage.

The bagasse has potential as an alternative feed for ruminant. However,  though the high of the crude fibre and the very low in the nutritional value make them very limited in using for animal feed. To overcome the problem in order to increase nutritional value was the fermentation technology by the application of the starbio inoculums. The objective of the research was to observe the  nutrition  qualities of the bagasse with aplication of different levels of starbio. The experimental design was  a completely Randomized Design  with 4 treatments i.e. P0 (bagasse + 0% Starbio), P1 (bagasse+ 0.2% starbio), P2 (bagasse+ 0.4% Starbio), P3 (bagasse+ 0.6% Starbio) and each treatment has 5 replication, The parameters measured were pH, dry matter (DM), crude protein (CP), ether extract (EE) crude fiber (CF), ash and Nitrogen Free Extract (NFE). The results of the research indicated that pH of the  fermentation was very good (3.37-3.67), DM (66.59-68.73%), and CP 1.47-1,97%. However, there was no effect on EE, CF, ashes and NFE. The addition of 0.6% starbio was the best result to increase CP but did not affect on ash content.

Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes.

Abstract A study was conducted to evaluate effects of increasing concentration of food grade glycerol on rumen environment and nutrient digestibility. Three ruminally cannulated Jersey steers were used in this study. The study was conducted from March to May 2019. Experimental design was a 3x3 Latin square with a 2wk adjustment period followed by a 1wk collection period. Diet was coastal bermudagrass hay based. Different forage types were introduced in the incubation process to evaluate digestibility. Glycerol was administered once a day at 0, 15, or 20% of DMI (dry matter intake). dNDF (digestible NDF) and dDM (digestible dry matter) was determined using an ANKOM Daisy II incubator inoculated with 200g fresh rumen fluid and incubated for 12, 24, 48 and 72 h at 39°C. Each vessel contained ground forage samples in filter bags in triplicate. After incubation, filter bags were rinsed with cold water and dried for 24h in a 55°C forced air oven. Data were analyzed using the Proc MIXED procedure of SAS version 9.4. There was no difference dNDF in effect of different levels of glycerol between forage types by diet. But a numerical tendency was observed that dNDF was decreased at 20% inclusion rates in comparison to 0 and 15% inclusion of glycerol in the diet. Neither steer nor run was significantly different in the study. However as expected digestibility over time was significantly different (P &lt; 0.001). A significant increase was observed in DMI with the increased levels of glycerol in the diet (P = 0.003), both the 15% and 20% levels of glycerol increased in DMI in comparison to the control (0%). It appears based on these study results that digestibility may be inhibited, as levels of dietary glycerol increase in the diet and more work needs to be done to find the optimal level of glycerol supplementation.

Four dairy steers were allotted to four lysine infusion levels in a 4 × 4 latin square design and fed an 11.5% crude protein (90% dry matter (DM)) diet continuously (10-min intervals every 24 hr). Lysine hydrochloride equivalent to 0.0, 3.0, 6.0, and 9.0 g lysine per day was infused per abomasum. When 9 g lysine were infused per day, the percent of absorbed nitrogen (N) retained was significantly (P < 0.05) reduced; urinary N excretion as a percentage of N intake and plasma-free lysine were increased significantly compared with the other three infusion treatments. The infusion of 9 g lysine per day apparently exceeded the body tissue requirements for this amino acid and the excess N was excreted in the urine. A possibility of lysine being limiting (0.28% lysine of a 100% DM diet) was apparently offset by the synthesis of lysine by rumen microorganisms, which increased the dietary lysine two- to threefold. Increased levels of infused lysine did not result in a linear increase of lysine in the abomasum. With 3 g per day lysine infusion rumen ammonia and N retentions were high. However, a smaller amount of N reached the abomasum with steers on this treatment.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.
