Weathering and mold growth in alfalfa (Medicago sativa L.) hay stored at 20% moisture in large round bales was extensive. The losses of dry matter were 9, 40 and 30%, respectively, for hay stored inside, outside and partially protected. Prolonged storage reduced the quality of the edible portion of hay. Key words: Alfalfa hay, digestibility, storage losses, recovery of nutrients

HighlightsTime to bind a round bale was longest for twine (56 s) compared to B-Wrap® (28 s) and net wrap (18 s).Alfalfa cultivar had minimal effects on changes in dry matter and forage quality of round bales stored outdoors.Dry matter losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM in outdoor storage.Deleterious changes in forage quality were generally observed after =180 days of outdoor storage. Abstract. Large round bales are commonly fed to livestock; however, it has been well documented that outdoor storage can negatively impact dry matter (DM) and forage quality. To reduce storage losses and improve feeding value, new wrap types and alfalfa cultivars have been developed; however, these options have not been extensively investigated. Therefore, the objectives of this research were to evaluate the time required to bind large round bales, determine changes in DM and forage quality, and examine the economics of reduced-lignin and conventional alfalfa hay bound in twine, net wrap, and B-Wrap® while in outdoor storage. Hay was baled into 24 large round bales; 12 bales each of reduced-lignin and conventional alfalfa. Within each cultivar, four replicates were bound with each wrap type. Using stopwatches, the time to bind each bale was recorded. At the time of harvest, and every 90±3 days for 365 days, individual bales were weighed and cored to determine changes in DM and forage quality. Significance was set at P = 0.05. Time to bind a bale was longest for twine, intermediate for B-Wrap®, and shortest for net wrap (P < 0.01). Alfalfa cultivar had minimal effects on the parameters measured; therefore, the interaction between wrap type and storage length was reported. After 365 days in outdoor storage, DM losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM. Changes in forage quality were observed at =180 days of storage where nonstructural carbohydrates were decreased and insoluble fiber components were concentrated. B-Wrap® bales had a higher value compared to net wrap and twines bales at 180 and 270 days in storage. These results suggest that B-Wrap® was better able to shed precipitation which preserved forage quality and bale value compared to large round bales bound in net wrap and twine in long term, outdoor storage. Keywords: B-Wrap®, Bale value, Net wrap, Reduced-lignin alfalfa, Twine.

A microbial profile of smoked dry herring stored under various storage conditions for up to 6 months at ambient temperature was determined. The fish were stored in polyethylene bags, polyethylene bags with desiccant, the traditional oven storage, modified storage structure, and freezer (control) storage. The fish stored in polyethylene bags with or without desiccant spoiled rapidly. Microbial counts were also very high. The microbial counts of fish stored in the traditional oven and the modified structure were small, even less than that stored in freezer. The storage losses were only 4% for the modified structure while the traditional oven storage was 29%. The major pathogenic bacterium found in smoked dry herring was Staphylococcus aureus.

Two experiments were conducted to assess the effects of storage conditions on the quality of large round bales (LRB). Samples were taken at 75-d intervals from LRB stored inside, outside single bales covered with a 15-mm black polyethylene plastic bag, outside uncovered as single bales, outside uncovered in a single row and outside uncovered in a double stacked row. Bales were sampled at depths of 0–15, 15–30 and 30–45 cm. Time, storage and depth factors had an influence on the chemical components of the LRB except for protein. Weathering had the most effect after 150 d of storage and with LRB stored uncovered and in the top 15-cm layer. Significant (P < 0.05) interactions in in vitro dry matter digestibilities were found for storage time × depth of sample, storage time × storage methods and for depth of sample × storage methods. Under the conditions of our experiments, weathering damages were limited to the superficial layer of LRB left uncovered. Key words: Large round bales, weathering, storage, moisture

Rumen fluid from two sheep was used to determine in vitro dry matter digestibilities of 25 samples each from alfalfa hay (Medicago sativa L.) and barley grain (Hordeum vulgare L.). The sheep were fed either a good quality hay ad libitum and 1 kg rolled barley per day, or only the hay ad libitum, in a switchback design. The in vitro dry matter digestibilities of both alfalfa hay and barley were lower (P < 0.01) when the donor animal was fed hay and barley than when fed only hay.

Until now there are only few data on the effects of thermal treatments on the nutritional and hygienic characteristics of donkey milk. This Research Communication aims to provide information on the effects of pasteurization (at +65 °C for 30 min) and prolonged storage at refrigeration and freezing temperatures (21 d at + 3 °C ± 2 °C and up to 90 d at −20 °C ± 5 °C) on some nutritional and hygienic characteristics of Amiata donkey milk. The milk was monitored by chemical and microbiological analysis. Pasteurization ensured compliance with EC Regulation No 1441/2007, as Enterobacteriaceae were never found in the milk, or during storage at refrigeration and freezing temperatures. Colony count at 30 °C in pasteurized milk never went beyond 1 log CFU/ml. The heat treatment and the storage did not result in any variations in the main constituents of the milk. Only a decrease in lactose and few variations in some fatty acids at 90 d of freezing were observed. In conclusion, pasteurization was able to achieve and maintain a high hygienic-sanitary quality over time; storage at refrigeration or freezing temperatures did not alter the nutritional quality of fat and the gross composition of the product. These findings are useful to improve knowledge on the milk shelf life in order to guarantee safety and nutritional quality for infants who need small quantities of daily milk.

Abstract The purpose of the study was to assess the storability of unripe hazelnuts in the husk of four cultivars: ‘Hall’s Giant’, ‘Catalan’, ‘Webb’s Prize Cob’ and ‘Cosford’. The nuts were stored in normal and controlled atmospheres, and in Xtend® bags for three months. A quality assessment was performed based on the following parameters: weight of the nut in the husk and without the husk, weight of the kernel, percentage of nuts with husk attached, dry matter content in kernels, infection with fungal diseases, and the presence of physiological disorders. The study demonstrated that hazelnuts stored in Xtend® bags and under a controlled atmosphere had a higher weight for the nut in the husk and without the husk, as well as a higher weight of the kernel and water content when compared to batches of hazelnuts stored in a normal atmosphere. The percentage of nuts remaining in the husk was also higher when stored under such conditions. For the majority of investigated cultivars the storage in Xtend® bags, and to a lesser extent under normal atmosphere conditions, resulted in a substantial increase in nuts infected with fungal and abiotic diseases. Among investigated cultivars, ‘Hall’s Giant’ turned out to be the most resistant to storage diseases.

Flowering potted plants during the postproduction stage are usually stored in inadequate environmental conditions. We evaluated the effect of the most common storage conditions and treatments on twoBougainvilleacultivars after harvest and during recovery. Flowering pottedBougainvilleaplants were treated with 100 mL 2 mM amino-oxyacetic acid (AOA) or 500 ppb 1-methylcyclopropene (1-MCP) prior storage in dark at 14∘C for simulating transport or storage conditions and, subsequently, transferred to growth chambers at 20∘C in the light for one week for evaluating the recovery ability. The plant stress during the experiments was assessed by ethylene, ABA, and chlorophyllafluorescence measurements. Ethylene production was affected by temperature rather than treatments. ABA concentration declined in leaves and flowers during storage and was not affected by treatments. Fluorescence parameters appear to be very useful for screeningBougainvilleacultivars resistant to prolonged storage periods.

The effects of cultivars, date and rate of seeding on the yield and quality of alfalfa (Medicago sativa L.) seeded at the end of summer and harvested the year after was studied from 1971 to 1975 on a Kamouraska clay. Seeding in early August gave the best results; seeding should not be carried out after mid-August. Differences between cultivars were more important on the third than on the first cut. Aftergrowth was an important factor on yield during the first year of harvest. Seeding rate did not always affect the yield, but the 6,7 kg/ha rate yielded less than the 13,4 kg/ha rate at the first cut and when the cuts were summed. The combined effects of the three factors studied indicates the importance of the seeding date on the height, cover and yield of alfalfa. Digestibility and crude protein content of the dry matter were affected more by seeding dates than by cultivars. The effect of cultivars on quality was variable and seeding rates had no effect. The variation in forage quality may be attributed to a difference in maturity of the plant at harvest, rather than only to the factors studied.Key words: Medicago sativa L., cultivar, date, rate, yield, quality
