Grazing Systems

The objective of this research was to evaluate of three grazing systems (GS) with elephant grass (EG), Italian ryegrass (IR) + spontaneous growing species (SGS); EG + IR + SGS + forage peanut (FP); and EG + IR + SGS + red clover (RC), during the winter and summer periods in rotational grazing with dairy cattle. Experimental design was completely randomized with three treatments, two replicates with repeated measures. Lactating Holstein cows receiving 1% BW-daily feed supplement with concentrate were used in the evaluation. Eight grazing cycles were performed during the experimental period. The values of pre forage mass and stocking rate were 2.52, 2.60 and 2.99 t ha-1 and 2.64, 2.77 and 3.14 animal unit ha-1, respectively for GS. Samples of forage were collected by hand-plucking technique to analyze the crude protein (CP), neutral detergent fiber (NDF), in situ dry matter digestibility (ISDMD), in situ organic matter digestibility (ISOMD) of forage present between rows of elephant grass, in the rows of elephant grass and the legumes. Higher value of CP, ISOMD and lower of NDF were observed for the grazing systems mixed with legumes forage.

The objective of this study was to compare the most widely grown barley cultivar in Canada, AC Metcalfe, a malting type barley, with five feed cultivars. Barley cultivars were grown at one location during 3 consecutive years and barley samples were milled to pass through a 1-mm screen and analysed to determine nutritive value. Additional samples were passed through a roller mill with a gap set at 1.12 mm and incubated ruminally for 0, 2, 4, 8, 12, 24, and 48 h in 3 dry Holstein cows fitted with rumen cannulae. The rate and extent of rumen digestion were estimated. AC Metcalfe had a higher (P < 0.001) concentration of NDF, and lower (P < 0.05) concentrations of non structural carbohydrates, starch, ADF, total digestible nutrients, and fermentable cell wall carbohydrates compared with the mean of the feed cultivars. The malting cultivar had a higher (P < 0.001) soluble DM fraction, lower (P < 0.05) CP and starch degradation rates, and a lower (P < 0.001) ruminally degradable starch concentration compared with the mean of the five feed cultivars. The results demonstrate that there are only small differences in terms of chemical composition and in situ degradation kinetics between the malting cultivar AC Metcalfe and the five feed cultivars of barley reported here.

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.

The in situ technique forms the basis of many feed evaluation systems for ruminants. Although this method is widely used, the NBT is very laborious, time-consuming, and incubations and analyses of the feed residues often last several weeks. Therefore, several other techniques have been investigated to measure and predict ruminal degradation of various chemical components of feedstuffs. The aim of this study is to investigate the possibilities of estimating in situ degradation characteristics of DM, CP, ADF and NDF in several feedstuffs by gas production characteristics and chemical composition.

In the Brazilian savanna region, which covers 2.1 million km2, roughage production is irregular during the year. However the manufacture of passion fruit juice produces approximately 13,000,000 ton per year of industrial residue which consist of fruit pulp and seeds (FPSR) (Medina, 1980). Beef and dairy cattle farmers are feeding it to their livestock with no knowledge of its nutritive value or concern for its pollution aspects. The FPSR is left in piles outside on the ranches and fluid effluent is often observed reaching streams and contaminating the environment. Furthermore it is a good medium for fly proliferation which stresses the animals and reduces profits. The objective of this study was to demonstrate to the farmers a better way for storing the FPSR and to determine its nutritional value for ruminants.The FPSR was stored in triplicate experimental mino-silos (200 1) in a complete 2x2 factorial design to observe the effects of 48-h wilting (sun dry) and anaerobic conditions. Open mini-silos were left uncovered while in anaerobic mini-silos the FPSR was sealed in plastic bags and covered with sacks of soil. Treatments were: Tl wilted and anaerobic; T2 wilted and open; T3 unwilted and anaerobic; T4 unwilted and open. The mini-silos were sampled at 30-day intervals for up to ll2 days. The samples were analysed for dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), lignin (LIN), phenolic compounds (PHEN), ammonia nitrogen (NH3 -N), soluble carbohydrats (CHO sol) and pH. The DM effective degradability (DMED) was determined “in situ” using six Santa Inês male sheep fitted with rumen cannula and fed with a mixture 80:20 diet containing grass pasture and concentrate (160 g CP/kg DM). The effects of experimental conditions were analysed in a factorial treatment structure and tested by analysis of variance. Treatment means were compared by contrasts.

Two Stages

The fresh weight, dry matter (DM) contents and nutritional quality in maize vary considerably with variation in varieties, stages at which harvested, climatic conditions and agronomic factors. Recently, agronomists, nutritionists, and dairy producers have placed increased emphasis on factors affecting the nutritive value of maize. However, very little information is available on quantitative variability of the feed value of maize fodder as affected by such factors. This study was, therefore, carried out to assess the effect of harvesting of six different maize varieties at two stages (dates) of grain maturity on quality of both the stover and cobs.

High Moisture Corn

Abstract Exogenous fibrolytic enzymes (EFE) improve the energy availability of grains for nonruminant animals by reducing encapsulation of the endosperm nutrients within grain cell walls; however, these benefits are unknown in the treatment of corn-based silage for cattle. The objective of the present study was to evaluate the effects of adding EFE at ensiling on the nutritive value of high-moisture corn (HMC) and snaplage (SNAP) for finishing Nellore bulls. The EFE dose was 100 g/Mg fresh matter in both HMC and SNAP. Diets were 1) a SNAP + HMC control (without enzyme addition); 2) SNAP + HMC EFE (with enzymes); 3) a whole-plant corn silage (WPCS) + HMC control (without enzyme addition); and 4) WPCS + HMC EFE (with enzymes). In addition to the silages, the diets were also composed of soybean hulls, soybean meal, and mineral–vitamin supplement. The statistical design was a randomized complete block with a factorial arrangement of treatments, and the experiment lasted 122 d. For in situ and in vitro analyses, 2 cannulated dry cows were used. There was no interaction between the diets and EFE application (ADG, P = 0.92; DMI, P = 0.77; G:F, P = 0.70), and there was no difference between the SNAP and WPCS diets regarding the DMI (P = 0.53), ADG (P = 0.35), and feed efficiency (ADG:DMI, P = 0.83). Adding EFE to the HMC and SNAP at ensiling did not affect ADG but decreased DMI (P = 0.01), resulting in greater feed efficiency by 5.91% (P = 0.04) than that observed in animals fed diets without the addition of EFE. Addition of EFE to HMC resulted in reduced NDF content and increased in vitro and in situ DM digestibility compared with untreated HMC. No effects were found for the addition of EFE to SNAP. Fecal starch decreased with EFE application (P = 0.05). Therefore, the diet energy content (TDN, NEm, and NEg) calculated from animal performance increased (P = 0.01) with the addition of EFE to HMC. In conclusion, exchanging the NDF from WPCS with that from SNAP did not affect the performance of finishing cattle, whereas the addition of EFE to HMC at ensiling improved animal performance by increasing the energy availability of the grain.
