The ensilability and chemical composition of silages made with different proportions (100:0; 90:10; 80:20; 70:30; 60:40 and 50:50%) of foliage (fresh and pre-wilted) and noni fruit (fresh) was evaluated. Some fermentative patterns of the original forages and the chemical content of the silages were determined. Correlations between the parameters of quality, chemical composition and the fruit levels in the mixture were made and adjusted the same one to polynomial equations. A higher inclusion of fruits with both fresh and pre-wilted foliage of noni decreases the pH and NH3-N Nt-1 in the silage. In addition, the increase in the level of fruit increased the concentration of water soluble carbohydrates (WSC) and the ratio of WSC/PC. Moreover, the pre-wilted foliage increased the dry matter (DM) content and its combination with fruit levels between 30 to 40% decreased the fibrous compounds and crude protein (CP) concentration in the silage. According to a cubic model used, the pre-wilted foliage and fruit proportions showed a higher R2 for DM, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent-lignin (ADL) and cellulose, while CP and hemicelluloses were higher in the fresh plant material. The results showed that the pre-withered process (foliage) and inclusion levels of 30 and 40% of fruits in the mixture improved the quality of the silage intended for animals.

Early Harvest

The chemical composition of plant components of three maize hybrids harvested at the beginning of six reproductive stages of maturity was compared. The hybrids evaluated included Maximus VIP3, Defender VIP and Feroz VIP, which were evaluated at each of following stages: R1 (grain formation), R2 (milky grain), R3 (pasty grain), R4 (floury grain), R5 (hard grain) and R6 (ripe grain). The advancement in maturation was linearly related to the crude protein (CP) content of the stem, whole plant, and leaves, and there was a difference among the hybrids. Between R4 and R5 stages, Maximus and Defender presented the highest CP contents for husk (6.58 and 5.42% for Maximus; 5.54 and 5.17% for Defender). The neutral detergent fiber (NDF) of the leaves showed a quadratic relationship with the advancement of maturation but did not differ among the hybrids. For all the hybrids, the NDF content in the husk and cobs increased linearly during the reproductive stages (>77 and 78%, respectively, for the three hybrids in R6). Defender had the lowest NDF content of the cob in R3. The acid detergent lignin contents did not differ among stages in the stems, and showed a linear decrease throughout the whole plant, though the contents did not differ among the hybrids. Due to the differences observed, recommendations for harvest based on the maturity stage for each hybrid should be taken into consideration. There seems to be no important distinction among hybrids for harvesting and use of straw. Despite the reduction in grain yield, an early harvest for earlage or snaplage can provide lower lignin content in husk and cob, as well as higher protein content in the husk, favoring the nutritional value of the vegetative fraction (husk and/or cob).

Abstract: The objective of this work was to evaluate the effects of combined phosphorus and nitrogen fertilization and of harvesting frequency on the chemical composition of 'Gigante' cactus pear (Opuntia ficus-indica) cladodes. The experiment was carried out in two municipalities, Quixadá and Tejuçuoca, in the state of Ceará, Brazil. Fertilization with nitrogen (urea) and phosphorus (single superphosphate) was done with nine doses, respectively: 10 and 70, 70 and 10, 70 and 70, 70 and 130, 100 and 100, 130 and 70, 130 and 130, 130 and 190, and 190 and 130 kg ha-1 per year, besides 100 kg ha-1 N and P2O5 per year as the control. The harvesting frequencies evaluated were annual and biannual. A randomized complete block design was adopted, in split plot, with four replicates. The effect of fertilization on the contents of total dry matter, crude protein, neutral detergent fiber, organic matter, and total carbohydrates in the cladodes varies with harvesting frequency and site. Regarding harvesting frequency, there were higher contents of organic matter, total carbohydrates, and neutral detergent fiber, but lower contents of crude protein for the biannual harvesting in both municipalities. Annual harvesting improves the nutritional quality of primary and secondary cladodes in the municipality of Quixadá and of secondary and tertiary cladodes in Tejuçuoca.

Research was conducted to determine the quality and chemical composition of silages obtained by mixing in different ratios of narbonne vetch (Vicia narbonensis L.) and barley (Hordeum vulgare L.) grown in rabi season of 2017-2018 in Eastern Anatolia, Turkey. In the study we studied the pure sowings of barley and narbonne vetch and their mixtures (20, 30, 40, 50, 60, 70, 80% of narbonne vetch (N) + 80, 70, 60, 50, 40, 30, 20% of barley (B). The values of ADF (acid detergent fiber), NDF (neutral detergent fiber), DDM (digestible dry matter), DMI (dry matter intake), DM (dry matter), CP (crude protein) and RFV (relative feed value) of silages of analyzed were respectively 33.38, 33.73, 62.89, 3.57, 24.69, 15.50%, 174.64. We also founded that LA (lactic acid), AA (acetic acid), BA (butyric acid), PA (propionic acid) and Ca, P, Mg, K and pH of silages investigated were respectively 1.60, 0.57, 0.42, 0.06, 1.17, 0.53, 0.25, 3.51% and 3.80. Our results shows that silages with high narbonne vetch were higher quality values for CP, ADF, NDF, DM, RFV, DDM, DMI, Ca, Mg, LA which determined chemical composition and feeding quality of silages. As a result, it is suggested that mixture silages with narbonne vetch (80%) and the barley ratio (20%) have important advantages for some properties of silages.

Barley Silage

The effect of ensiling barley treated with two bacterial inoculants containing mixtures of Lactobacillus plantarum and Enterococcus faecium (1.0 × 105 cfu g−1 as fed silage) on the nutritional value and aerobic stability of barley silage was examined. Inoculants differed in the strains they contained and were originally selected by Pioneer Hi-Bred International for use with corn or alfalfa silage, SILA-BAC® (1174), or with grass silage (X2637). Concentrations of water-soluble carbohydrates were higher (P < 0.05) in inoculated than in control silages. Although inoculants appeared to increase the numbers of lactic acid producing bacteria (LAB) at ensiling, post-ensiling numbers (cfu g−1) of yeasts and molds were lower (P < 0.05) in inoculated than in control silages. Lactic acid concentrations and pH were similar among the silages and variations m the growth of yeast and mold populations could not be explained by differences in the production of volatile fatty acids (VFA) among silages. Inoculation of barley silage with either inoculant increased (P < 0.01) the average daily gain of lambs. A digestibility experiment with 12 growing ram lambs showed that inoculants did not alter (P > 0.05) DM intake, feed efficiency or the digestion of DM, organic matter, acid detergent fiber (ADF) and neutral detergent fiber (NDF). Nitrogen intake and retention were greater (P < 0.05) in lambs fed silage inoculated with 1174 as compared with control silage. Yeast populations were increased (P < 0.05) in control and 1174 after 2 d of exposure to air but it required 13 d for a similar yeast population to be established in X2637 silage. Increases in the mold populations within the silages were noted after 2, 5 and 13 d of exposure to air for control, 1174 and X2637, respectively. The temperature of control silage increased (P < 0.05) 2 d after exposure to air, whereas increases in temperature were delayed for 4 d in 1174 and 8 d in X2637. Temperatures rose as high as 30 °C in control silage, but did not exceed 24 °C in inoculated silages during the 13 d period.

Maize cultivation for silage could be a sustainable option in Boreal conditions, especially when combined with nutrient recycling. Effects of digestate (sludge from biogas of domestic origin) application in comparison with synthetic fertilizer and two maturity stages on chemical composition and in vitro digestibility of whole-crop maize were investigated. Starch, neutral detergent fiber, water soluble carbohydrate (WSC) and digestible organic matter (DOM) contents of maize did not differ in response to the two fertilizer treatments. However, starch, DOM and metabolizable energy of maize increased, while ash, crude protein and WSC contents decreased with increasing maize maturity. Heavy metals in maize fertilized with digestate remained low. The results indicate that whole-crop maize fertilized with digestate and harvested at 150 days after sowing is a promising feed and has good nutritive value, even in Boreal conditions.

Buffalo milk mozzarella is often adulterated by the addition of cow’s milk. The aim of this study was to assess the quality of buffalo milk mozzarella by using electrophoresis (SDS-PAGE) to detect the addition of cow’s milk. Reference cheeses were produced exclusively from combinations of buffalo and cow milk, and labeled reference treatment buffalo or cow (RTB and RTC, respectively). Standardized cheeses were made by combining buffalo milk and 2.5%, 5.0%, 10%, 20%, 30%, 40% or 50% cow’s milk. A total of 9 cheese formulations were produced and either frozen immediately (time 0) or after 20 days (time 20). Eighteen commercial samples of buffalo mozzarella were sampled between 0–20 days of production. The chemical composition (moisture, ash, fat in dry matter, protein, total solids and defatted dry extract) and physicochemical characteristics (acidity) of the cheeses were evaluated. Proteins and water-soluble peptides (WSP) extracted from RTB, RTC and from the commercial samples, and were analyzed by SDS-PAGE electrophoresis under denaturing conditions. It was not possible to detect the inclusion of cow’s milk by the cheeses’ chemical and physicochemical properties. However, the separation and detection of peptide and protein fractions of the cheese was possible by electrophoresis. The results of the electrophoretic analysis suggest that 28% of the commercial samples considered here had evidence of the addition of cow’s milk. The methodology described here is important to identify occurrences of fraud in buffalo mozzarella production.

HighlightsJuice extraction resulted in a decrease in the nutritive value of the bagasse as compared with the initial biomass.Silages made from the second pressing bagasse were well conserved.Sweet sorghum silage has a better nutritive value than sweet pearl millet.Abstract. Pressing the biomass of sweet sorghum and sweet pearl millet in-field is one of the suggested options for bioethanol production. The extracted juice can be delivered to an ethanol plant, and the bagasse (pressing residue) can be used for ruminant feeding. Efficient carbohydrate extraction is highly important for good ethanol yield. However, enough carbohydrates must remain in the bagasse for its adequate conservation as silage. In this study, the ensilability and the chemical composition of the second pressing bagasse of sweet sorghum and sweet pearl millet were investigated. The bagasse was obtained following a second pressing of the first pressing bagasse after its impregnation with water based on three water:bagasse ratios (0.5, 1, and 1.5). Results indicated that water:bagasse ratio did not affect water-soluble carbohydrate (WSC) extraction for both crops. The second pressing bagasse of sweet sorghum and sweet pearl millet contained 80.5 ±4.6 and 60 ±4.6 g of WSC kg-1 dry matter (DM), respectively. The second pressing bagasse of both crops had reduced nutritive value compared to the initial biomass, i.e., higher neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations along with lower non-structural carbohydrate (NSC) concentration, in vitro true digestibility of DM (IVTD), and in vitro NDF digestibility (NDFd). The second pressing bagasses of both crops also showed good ensilability, but sweet sorghum bagasse silages were of better nutritive value than sweet pearl millet bagasse silages (ADF = 446.2 ±3.7 vs. 463.2 ±3.7 g kg-1 DM, IVTD = 813.8 ±3.4 vs. 708.8 ±6.8 g kg-1 DM, and NDFd = 741.8 ±4.8 vs. 596.2 ±8.5 g kg-1 NDF, respectively). The water:bagasse ratio used for bagasse impregnation before the second pressing only affected the NDF concentration of silages, as a higher NDF concentration was obtained with a water:bagasse ratio of 1.5. Sweet sorghum and sweet pearl millet can be considered dual-purpose crops; the extracted juice can be fermented into ethanol, and the second pressing bagasse can be used to make good-quality silage.

Fresh whole plant spring triticale (x Triticosecale spp.) was field wilted and chopped prior to either being sprayed or not with a homolactic bacterial inoculant (HBI). Wilted triticale was ensiled for 120 d at 20 to 23 °C using 16 PVC mini-silos of 3 L capacity fitted with two-way mechanics to vent gas (which imposed aerobic stress (ASTS) when it remained open), and filled with about 2 kg of the crop containing 35% dry matter (DM) and 5.2% water soluble carbohydrates (WSC) in the DM. Four treatments of a 2x2 factorial were: 1) No HBI/vent closed; 2) HBI/ vent closed; 3) No HBI/vent open; 4) HBI/vent open. Upon opening the mini-silos, chemical composition, fermentation characteristics and in vitro 30 h neutral detergent fiber (NDF) digestibility of the silages were determined. Relative to pre-ensiled forage, either sprayed or not with HBI, ensiling increased (P<0.05) contents of moisture, inorganic matter, fibrous fractions (acid detergent fiber (ADF) and lignin), and ether extract (EE), while decreasing contents of WSC and non-fibrous carbohydrates (NFC). However, treatment had no consistent effect on content of silage nutrients. Of the two non-inoculated silages, the one subjected to ASTS was more than 20 percentage points lower (66 vs. 88 %) in DM recovery (DMR), whereas the HBI silage subjected to ASTS was protected from DM losses. Ensiling and ASTS during the 120 d fermentation decreased NDF digestibility, whereas inoculated non-ASTS silage was nearly as digestible (57.5) as the pre-ensiled forages (58.2 and 60.7%, without and with HBI). Inoculation tended to steer fermentation in a homolactic direction. On balance, HBI is recommended because of the benefits in the fermentation pattern, fiber digestibility and DMR, especially in the presence of ASTS.

The objective of this study was to determine the chemical composition and in situ ruminal degradability of normal and brown midrib (bmr) forage pearl millet [Pennisetum glaucum (L.) R. Br.] grown in southwestern Québec conditions. Forage was harvested twice during the season. Relative to normal genotype, bmr millet contained less (P < 0.05) neutral detergent fiber (NDF) and acid detergent lignin and more (P < 0.05) crude protein (CP). Fiber fractions were similar for the two harvests. However, CP content was higher (P < 0.05) in the first than the second harvest. In situ ruminal degradabilities of DM, CP and NDF were all higher (P < 0.05) for bmr than normal forage millet and were not affected by harvest.
