Pistachio hulls are pistachio processing by-products produced during de-hulling of pistachio nuts soon after harvesting. Total pistachio by-products in Iran have been increased at an average rate of about 300000 Tons per year. Chemical composition of Pistachio hulls contained 12%CP, 5%EE, 34% NDF, 21% ADF, and 9% ash (DM basis). The dry matter content of fresh Pistachio hulls is about 28%. Reducing the moisture content of this by-product with dryer systems is a cost effective process and can not be applied by most of the producers. Finding other alternative methods for preserving and using this by-product is highly required. The objective of the present study was to assess changes in Pistachio hulls silage (PHS) quality associated with the inclusion of different levels of urea (U) and molasses (M), and to compare in situ DM and protein degradability of PHS with dried pistachio hulls (DPH).

The objective was to determine chemical composition and in situ degradability for silages of dual-purpose sorghum hybrids. Twenty-five hybrids of double-purpose sorghum were investigated in a randomized block design with three replicates. Ammoniacal nitrogen (NH3-N), pH, chemical composition of the silage and in situ degradability were determined. Silage of the hybrids 9929012, 947216, 947030, 947254, 947072, 947252, 12F042066, 1141570 and 1141562 presented greater dry matter content, ranging from 402.9 to 470.7 g kg-1. The greatest crude protein content was presented by silages from the hybrids 9929036, 9929030, 12F042224, FEPAGRO19, FEPAGRO11, 9929026, 947030, 947072, 947252, 12F042226 and BRS Ponta Negra. The silage of hybrid 1141562 exhibited the lowest neutral detergent fiber content (588 g kg-1). The highest values of dry matter and crude protein degradability were observed in the silages of the hybrids 9929030, 947252, 947072, 12F042066 and 12F042226. The use of ensilage of the 9929030 and 12F042226 hybrids is recommended because these silages present a better chemical composition of dry matter, crude protein and neutral detergent fiber and better dry matter and crude protein degradability.

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were  evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five  treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia  nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and  reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.

SummaryThe effects of the time of sowing on growth and chemical composition of carrots grown from May to November were studied during 3 years.Delaying sowing for 1 or 2 months after the beginning of May resulted in a reduction in the growth of both roots and foliage and gave roots with lower dry-matter content and glucose/fructose ratio but higher amounts of hexoses, total nitrogen and amino nitrogen in root dry matter. Sowing date had no influence on the concentration of sucrose, phosphorus, potassium, calcium and magnesium in root dry matter up to 137 days from sowing. Carotene decreased only after the last sowing. Sucrose concentration of the roots increased throughout the periods studied irrespective of the time of sowing. The longer the growing period the higher was the sucrose concentration. The concentration of hexoses decreased from the first harvest at 70 days to reach a constant level at about 130 days from sowing.The results did not indicate the presence of a well-defined stage of biochemical maturity in the autumn when carrot roots are expected as most suitable for harvest and subsequent long-term storage.

Summary Modifications in growing techniques can affect the yield and nutritional quality of various cultivated plants. Among them, the use of biostimulants is environmental friendly method of stimulating crop productivity, stress resistance, and affecting yield or chemical composition of the plants. The aim of the investigation was determining of the effect of biostimulant treatment on yield and its quality of carrot grown for summer harvest. The experiment was carried out in 2009-2011 in the experimental station of the University of Agriculture in Krakow, south Poland. Two experimental factors were taken into consideration: (1) cultivar: Nandrin F1 and Napoli F1 (2) dose of Aminoplant (foliar application): 1.5 and 3.0 dm3∙ha-1 and control (without Aminoplant). Total and marketable yield, root length, its diameter, leaf mass and leaf : root mass ratio were assessed. The dry matter, soluble sugar, carotenoids and nitrate ions contents were analyzed as main determinants of carrot nutritional quality. Aminoplant influenced not only carrot productivity, but mainly chemical composition of the roots. The present results also suggest that carrot reaction to biostimulant treatment was depended on a cultivar more than on environmental conditions in particular growing seasons. The significant effect of Aminoplant in a dose of 1.5 dm3∙ha-1 on the yield of roots and leaf rosette mass of ‘Nandrin F1’ appeared only in the first year of the experiment. Spraying with Aminoplant in a dose of 3.0 dm3∙ha-1 significantly increased the soluble sugars content in carrot roots of both cultivars but only in 2011. Dry matter content was also affected by biostimulant treatment mainly for ‘Napoli F1’, which showed the lowest dry matter content when sprayed with Aminoplant in a dose of 1.5 dm3∙ha-1. In 2010 control plants contained the greater amount of carotenoids, while in next year roots of plants treated with Aminoplant in a dose of 3.0 dm3∙ha-1 had more these compounds. The significant effect of Aminoplant on nitrates content in carrot roots was observed but were not repeatable in the experimental years, so different climatic conditions modified carrot reaction on biostimulant spraying.

Background: Tropical grasses, such as elephant grass, have high moisture content during its ideal phenological state for silage. High moisture content hinders proper preservation and reduces the nutritive value of silage due to secondary fermentation and production of effluents. Adding feed materials with high dry matter content, such as murumuru (Astrocaryum murumuru) meal, is a potential alternative to improve silage yield. Objective: To determine the effects of including murumuru meal (0, 7, 14, 21, and 28%) on the fermentative characteristics, microbiological activity, aerobic stability, and chemical composition of elephant grass silages. Methods: A completely randomized design with five treatments and five replicates was used. Elephant grass was collected at 60 d of age, minced, and homogenized with murumuru meal. The mass was placed in experimental 15-L silos. The silos were collected and analyzed 45 d later. Results: Effluent production decreased (p<0.05) as the proportions of murumuru meal in silage increased. A quadratic effect (p<0.05) was observed on dry matter recovery. An increase (p<0.05) was observed in dry matter content, a decrease (p<0.05) in the neutral detergent fiber content, and an increase (p<0.05) in the non-fibrous carbohydrate content with the inclusion of murumuru meal. Conclusions: Addition of murumuru meal improves chemical composition and does not affect the fermentative characteristics of elephant grass silage, while it reduces effluent losses. Nevertheless, the inclusion of murumuru meal in the elephant grass silage decreased the time of aerobic stability.

In trial one, seven lactating Holstein cows fitted with rumen cannulae were used in a replicated 3 × 3 Latin square design to investigate the effect of feeding alfalfa/grass ensiled at three dry matter (DM) levels (27.5, 46.1 and 56.4%) on the rate and extent of protein degradation. Cows were fed a total mixed ration of 70% alfalfa/grass silage, at one of three DM levels, and 30% concentrate (high moisture corn and mineral) (DM basis). Silage samples were incubated in sacco in the rumen for up to 48 h to model disappearance of DM, neutral detergent fibre (NDF) and nitrogen (N). Passage rates of silage, using Cr-mordanted NDF, were determined for small and total particulate fractions. Rates of DM, NDF and N disappearance, as well as rates of passage were unaffected by silage DM content. The 27% DM silage contained a larger soluble N fraction, but a smaller fraction of potentially digestible N than either the 46 or 56% DM silages. Estimates of effective protein degradability corrected for microbial contamination of digesta residues, for the 27, 46 and 56% DM silages were 75.8, 71.2 and 65.0%, respectively. In a second trial, 30 Holstein cows in mid-lactation were fed the same silages as in trial 1 using a completely randomized design. Milk protein percent and yield were higher (P < 0.05) for cows fed the 56% DM silage than those fed the 27 or 46% DM silages. Wilting alfalfa/grass silages prior to ensiling decreased estimated net ruminal silage protein degradation, which was associated with improved milk protein yield.

Samples of freshly cut wheat were exposed in freezing chambers, then stook-cured, threshed, and compared with unfrozen check samples, in the seasons 1929, 1930 and 1932, at Edmonton, Alberta. The check samples attained approximately maximum grade and weight per bushel when cut at a stage of maturity represented by a dry matter content ranging in different varieties and seasons from 50 to 60%. The weight per 1000 kernels of Marquis wheat, determined in 1930 only, reached a maximum at the same stage as weight per bushel. Susceptibility to superficial injury by frost continued generally over nearly the whole maturation period. Even 4 degrees of frost (28° F.) frequently caused a cut in grade, while 8, 10 and 14 degrees caused more substantial degradation, often accompanied by some reduction in weight per bushel. Marquis wheat is apparently more susceptible than Garnet, Reward and Red Bobs, to degradation by frost during the maturation period. Grade, being based on external appearance, is more sensitive to frost than are chemical composition and baking quality. Classification of the kernels of Marquis, in 1930, into vitreous, starchy, immature, green, bran frosted and heavily frosted, confirmed the earlier conclusion (2) that only the sound class (vitreous + starchy) has enough relation to grade to be useful as a grading factor. The germination of Garnet was improved by moderate freezing.

Forage quality is a key factor in dairy cattle nutrition. High moisture forages are so susceptible to loss their nutrients during ensiling. Canola is one of the oilseed plants that belong to Brassica species. Canola forage has high level of moisture in its tissues and must be wilted to 60 -65% moisture before ensiling. On the other hand, molasses and urea as two silage additives can be effective in improvement and preservation of canola forage quality. Molasses is commonly used to provide readily available energy for lactic acid fermentation. Addition of molasses can increase dry matter content of silage that related to relatively high dry matter content of molasses (Baytok and Aksu, 2005). Meanwhile, silage protein content can be increased and proteolysis decreased with the addition of urea. Application of urea to harvested forage before ensiling can restrict the fermentation processes and release ammonia to potentially enhance nutritive value of the ensiled crop and reduce deterioration during storage. The main objective of this study was to evaluate effects of different levels of urea and molasses on chemical composition and in vitro DM digestibility of whole crop canola silage.
