The forage quality of habitats associated with mature conifer plantations and the use of these habitats by resident snowshoe hares (Lepus americanus) were evaluated. The winter forage of hares was composed of deciduous stems that were predominantly low in protein content and not preferred. The crude protein content of the principal browse species, Viburnum dentatum, was only 4.6–6.4% during winter months. However, snowshoe hares feeding on the low-protein browse maintained their body weight. The intake of protein was maximized by the consumption of stem ends, which compensated for the low-protein forage. Use of habitat by snowshoe hares was closely related to the vegetative cover but did not correlate well with forage availability. Sites preferred by hares had a well-developed overstory (mature spruce) but only sparsely available forage during the winter. Thickets of early-successional deciduous vegetation had high use and contained most of the low-protein browse.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

Midas marrowstem kale (Brassica oleracea L.) was grown in different row width associations with United 106 corn (Zea maize L.) in two studies and ensiled in different moisture blends with corn stover in another. Highest dry matter yields were obtained where a single row of kale was grown at 30 cm to the side of a corn row. This combination also provided the lowest moisture content feed and the highest in vitro digestibility and crude protein content. Changing the corn row width had no significant effect upon yield, plant height, in vitro digestibility, kale leaf or corn ear content. Blending kale with corn stover to provide a silage of about 70% moisture increased the digestibility and protein content of the feed and provided a silage that kept well in storage.

AbstractThe use of low-protein (LP) feeds is a good strategy to reduce the environmental release of N compounds, but their influence on the quality of the products must be considered. This study explored the influence of LP diet and two pig breeds (BR) with different lean growth ability on the quality traits of dry-cured hams. We analysed 40 left dry-cured hams from pigs of two BR [Duroc-Danbred crosses (Danbred) and Duroc × Large White crosses (Anas)] fed either conventional (147 to 132 g/kg, crude protein) or LP diet. The LP had a crude protein content reduced by 20% with respect to the conventional. The differences in ham quality resulting from protein reduction were small, with a decrease of the protein and an increase of the lipid content of the ham slice in Anas, but not in Danbred (BR × Diet interaction; P = 0.043). Therefore, the use of LP would be feasible and sustainable, without detrimental effects on products. It was found the pig genotypes with different potentials for lean growth may affect the initial ham weight, fat cover and seasoning losses of hams, but they appear to affect little other chemical, physical and textural quality traits of the dry-cured hams.

Abstract This study aimed to evaluate the chemical and fermentation quality of silage from two sorghum hybrids in different layers of the silo feed-out face, as well as the interference of the aerobic exposure time of structured and/or unstructured silo face (after feed-out). The AG-2005E hybrid silage presented higher crude protein content and higher pH compared to hybrid AG-60298 (6.33% and 4.0 versus 6.06% and 3.8, respectively). Silages from stratum 0 to 20cm had the lowest dry matter content and the highest crude protein content (38% and 6.35%, respectively). The pH did not differ between layers, and the NH3 content was higher in the stratum 60 to 80cm (4.5%). During 72 hours of aerobic exposure, the unstructured silage presented a higher increase in temperature than the silage from the structured face, but this period was not enough to result in differences in dry matter, mineral matter, NH3, and pH. The chemical and fermentation quality of the silage was directly influenced by hybrid and silo stratum. After aerobic exposure, silage from the structured face seems to suffer less interference compared to the silo feed-out face.

Oil palm press fibre is a byproduct of agro-industry that has a low nutrient content. To improve the nutritional quality of oil palm press fibre, it is carried out with biological processing techniques utilizing the work of indigenous microorganisms derived from local microorganisms of it. The research was conducted experimentally using a completely  randomized design (CRD) factorial pattern with 2 factors (3 x 3), namely first factor such as dose of local microorganisms (D 1 = 1%, D 2 = 3% andD 3 = 5%) and second factor such as long of fermentation (L1 = 7 days, L2 = 14 days and L3 = 21 days), with 3 replications. The parameters of this study consisted of the nutritional content of oil palm press fibre fermented such as moisture, dry matter, crude protein, crude fat, crude fiber, ash, and BETN. Based on the results of the study, it was found that the combination of treatment with a dose of local microorganisms 5% and fermentation time of 14 days had a significant effect (P<0.05) in increasing crude protein content and did not have a vegetable effect (P>0.05) in increasing the dry matter content and BETN and reducing water content. , crude fat, crude fiber and ash. Giving various doses of local microorganisms and fermentation time can increase crude protein content and have not been able to increase dry matter and BETN content and reduce moisture content, crude fiber and ash.

One of the major uses of soybean crops (Glycine max (L.) Merril) is as silage. However, due to its unpleasant odour and relatively high butyric acid content, soybean silage is not readily preferred by animals. Because it does not have a regular fermentation, easily fermented forage resources are needed to obtain quality silage. To improve the quality of the silage, soybeans can be mixed with an appropriate amount of maize (Zea mays L.). In this study, we examined the quality and properties of maize (M) and soybean (S) silages of different mixtures (100 % M, 100 % S, 10 % S + 90 % M, 20 % S + 80 % M, 30 % S + 70 % M, 40 % S + 60 % M, 50 % S + 50 % M, 60 % S + 40 % M, 70 % S + 30 % M, 80 % S + 20 % M and 90 % S + 10 % M). For this purpose, each plant species was grown separately, and the maize was harvested when the plants reached the doughy stage. The harvest was performed using a single row maize harvester that chops the plants into 1.5-2 cm pieces. The fresh plant material from each species was then mixed in different proportions and squeezed before being transferred to 1.5 L anaerobic jars (Le Parfait, France). The jars were opened after a 60-day ensiling period. Then, the dry matter rate, pH, silage loss, fleig point, crude protein content, ADF content and NDF content of the silages were determined. The results showed that an increase in soybean rate in the mixture decreased the dry matter rate. Conversely, the silage pH, crude protein content and ADF content increased. Our results suggested that producing quality silage required the soybean material to be mixed with a minimum of 50 % maize.

SummaryA 4–year experiment was conducted at two sites in each year to evaluate some of the effects of five harvesting treatments on the forage and grain production and quality of four spring barleys sown in November and grown under rainfed conditions. A single harvest during the growing season at the milk stage of grain produced the highest herbage drymatter and digestible yields.One harvest at tillering reduced significantly the plant height, grain production and dry-matter yields of straw and hay, while the digestibility of the organic matter in the dry matter (D-value) and the crude-protein content of straw, crudeprotein content of grain and the number of tillers were not affected. The weighted mean of D-value and crude-protein content of herbage was increased when a ‘grazing’ cut was taken prior to harvest. In addition lodging was eliminated. Three or four harvests during the growing season resulted in very low forage yields of otherwise excellent quality.
