Row Width

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.

Yield And Quality

At Kyabram, Victoria, the effects of growth stage at cutting on dry matter (DM) yield and quality of lucerne was determined during the warm season haymaking period for cultivars with contrasting winter dormancy characteristics. Growth stages at cutting were pre-flower bud, flower-bud, 10% bloom and full bloom. Cultivars were winter non-dormant CUF 101 and Pioneer Brand 572, semi-winter dormant Pioneer Brand 581 and winter dormant Pioneer Brand 545. Cultivar responses or interactions between cultivar and growth stage at cutting were not significant (P>0.05) for dry matter yield, crude protein or in vitro digestibility. Cutting of the pre-flower bud stage, compared with cutting at the 10% bloom stage, reduced DM yield by 18% (16.4 v. 13.5 t/ha), but increased crude protein content of the lucerne from 19.3 to 24%. The total protein yield per hectare was not affected by cutting stages from pre-flower bud stage to 10% bloom. Cutting lucerne at the flower bud stage rather than at 10% bloom gave increased protein content and digestibility with only a moderate yield decline. However, more frequent cutting was unsatisfactory as it decreased the density of the stand and increased the proportion of weeds and so could not be recommended.

Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

ABSTRACT The present study aimed to assess the influence of pruning on the starch yield and nutritional value of the aerial parts of industry- purpose cassava clones adapted to the Cerrado region of Central Brazil. Four elite clones were submitted to either total shoot pruning or no pruning at 12 months after planting, in a randomized complete block design with three replications. Plants were evaluated eighteen months after planting. Clone 330/09 presented the highest root yield with and without pruning, and also higher starch yield, green and dry mass yields, and crude protein yield of aerial parts without pruning. In plants that were pruned, clones 117/09 and 359/09 stood out, with higher yields of the crude protein content of the aerial part and a higher in vitro digestibility of the dry matter. These clones are therefore an option when using the aerial parts of cassava in animal feed. Total pruning at 12 months of age significantly increased the crude protein content and in vitro digestibility of the dry matter of the aerial parts, improving its nutritional value. Pruning did, however, reduce the starch yield of the roots and the total yields of the roots and aerial parts.

Yield And Quality

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

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.

Seasonal changes in the quality of pinegrass (Calamagrostis rubescens) on native forest range in southern British Columbia included declines in crude protein content and in vitro digestibility of dry matter and increases in content of lignin, acid-detergent fiber, and ash. The decline in average daily gains of beef heifers was more rapid than changes in quality of the pinegrass over the grazing period from June to October.Pinegrass contained adequate nutrients for the rapid growth of yearlings or for maintaining weanling calves until August 1, whereupon protein and phosphorus supplementation were required. Nutrient requirements of pregnant cows and replacement heifers were adequately met until September 1.Copper and zinc were inadequate throughout the season. Calcium, iron, and manganese contents, however, were satisfactory. Silica was high and must be considered a potential problem in pinegrass utilization.Digestible dry matter gave a high positive correlation with crude protein and phosphorus and a high negative correlation with lignin, acid-detergent fiber, and total ash.Crude fiber, crude fat, and total soluble carbohydrate contents of pinegrass did not closely follow changes in either animal gains or in vitro digestible dry matter.Crude protein, phosphorus, and acid-detergent fiber appear to give a good indication of animal yields on pinegrass and could be used to evaluate pinegrass quality where animal data are not available.

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.
