Dry Forages: Process and techniques (OK-Net EcoFeed Practice Abstract)

To obtain the best forage quality, cutting at the correct time is important, when cellulose and lignin content is not too high. During spring, cutting early is the best option to preserve forage quality; for grasses, the correct time is beginning of heading; for leguminous plants, it is beginning of blooming. However delaying cutting increases dry matter (DM) content, which speeds up the drying process. Favourable weather conditions can reduce drying costs. Making hay decreases the moisture content to 15 % and increases dry matter (DM) to 85 %. Cutting height (Figure 2) is important for a perennial crop, affecting speed and quantity of regrowth. Generally is not recommended cutting too close to the ground, because basal buds are the slowest to refill and have low vigour. • Spreading the grass at cutting helps to decrease drying time and minimise forage quality and quantity losses. On field crushing of stems using a conditioner, increases water loss by up to 30 % and increases DM. The drying process can be completed on the field or in drying rooms, where forage quality is highest. At the end of the drying process, the hay can be baled and stored

Structural basis for the inhibition of RecBCD by Gam and its synergistic antibacterial effect with quinolones

Our previous paper (Wilkinson et al, 2016) used high-resolution cryo-electron microscopy to solve the structure of the Escherichia coli RecBCD complex, which acts in both the repair of double-stranded DNA breaks and the degradation of bacteriophage DNA. To counteract the latter activity, bacteriophage λ encodes a small protein inhibitor called Gam that binds to RecBCD and inactivates the complex. Here, we show that Gam inhibits RecBCD by competing at the DNA-binding site. The interaction surface is extensive and involves molecular mimicry of the DNA substrate. We also show that expression of Gam in E. coli or Klebsiella pneumoniae increases sensitivity to fluoroquinolones; antibacterials that kill cells by inhibiting topoisomerases and inducing double-stranded DNA breaks. Furthermore, fluoroquinolone-resistance in K. pneumoniae clinical isolates is reversed by expression of Gam. Together, our data explain the synthetic lethality observed between topoisomerase-induced DNA breaks and the RecBCD gene products, suggesting a new co-antibacterial strategy

Honey bee foraging distance depends on month and forage type

To investigate the distances at which honey bee foragers collect nectar and pollen, we analysed 5,484 decoded waggle dances made to natural forage sites to determine monthly foraging distance for each forage type. Firstly, we found significantly fewer overall dances made for pollen (16.8 %) than for non-pollen, presumably nectar (83.2 %; P < 2.2 × 10−23). When we analysed distance against month and forage type, there was a significant interaction between the two factors, which demonstrates that in some months, one forage type is collected at farther distances, but this would reverse in other months. Overall, these data suggest that distance, as a proxy for forage availability, is not significantly and consistently driven by need for one type of forage over the other

Report on the forage and feed product flow in Kenya (Busia, Bungoma, Kakamega and Siaya Counties)

Kenyan economy expanded 4.7% in 2017 and 6% in 2018 (World Bank, 2018). This growth was mainly supported by growth in agricultural output, among other steady economic growths such as industrial activity and service sectors. Agriculture is a huge contributor in terms of GPD with livestock taking a key position in this contribution. There is high demand for livestock products, which in turn creates a high demand for forage and feed. The availability of forage and feed is challenged by inadequate rainfall, overstocking, lack of knowledge and technology among others. However, famers are becoming persistent by using various ways in order to counter these challenges; among them production, conservation and purchase of forage and feed. This study examines the flow of forage and feed in selected counties in Kenya. A mixed research technique was applied using questionnaire as instrument of choice to conduct interviews with livestock farmers. The study found that most of the forage and feed consumed by livestock in these areas comes from respondents’ family lands. The study also found that most of the livestock diet is comprised of crop residues. Almost all the respondents in the counties agreed that planning forage and feed is not an expensive endeavor. Almost all the respondents said that buying forage and feed is an expensive engagement across the four counties. There is therefore room to increase productivity in terms of quality and quantity of forage and feed in these counties, through forage and feed farming

Maximizing Forage Yields in Corn Silage Systems with Winter Grains

Producing sufficient high quality forage on farms is becoming difficult given current economic and environmental pressures. Farmers are looking for strategies to improve yield and quality of their own forage to reduce the financial burden of purchasing feed off-farm. One strategy for accomplishing this is utilizing winter grains, such as rye, wheat and triticale, as forage crops. These crops could be grazed or harvested in the fall to extend the grazing season, and in the spring could provide early forage prior to planting corn silage. In the fall of 2015 the University of Vermont Northwest Crops and Soils Program initiated a trial investigating the integration of winter grains for forage into corn silage cropping systems

Ryegrasses: An Option for an Annual Forage Crop in Alaska

Annuals are often planted for a forage crop in Alaska, often on land that is being renovated or on newly cleared land, thus providing a longer opportunity for worldng the soil before seeding a perennial. Oats (Avena sativa) and barley (Hordeum vulgare) , sometimes seeded with a legume, are the most important annuals used for forage in Alaska. Cereals can provide a high-yield , late-summer forage crop, stored as hay or silage. Ryegrass (Lolium), another annual not now in significant use in Alaska , affords an option that merits consideration in forage programs

Maximizing Forage Yields in Corn Silage Systems with Winter Grains

Producing sufficient high quality forage on farms is becoming difficult given current economic and environmental pressures. Farmers are looking for strategies to improve yield and quality of their own forage to reduce the financial burden of purchasing feed off-farm. In addition, with increasing focus on managing farm nutrient balances for environmental reasons, farmers are also looking to decrease the importation of additional nutrients from feed onto their farms. One strategy for accomplishing this is utilizing winter grains, such as rye, wheat and triticale, as forage crops. These crops could be grazed or harvested in the fall to extend the grazing season, and in the spring providing early forage prior to planting corn silage. The fall planted forage also provides essential soil cover during winter months to reduce soil and nutrient loss. In the fall of 2016, the University of Vermont Northwest Crops and Soils Program initiated a trial investigating the integration of winter grains for forage into corn silage cropping systems

Forage Yields in Turkey Hill Wilderness in East Texas for White-tailed Deer

Wilderness areas are often considered quality areas where natural processes occur without human activity. It is often assumed that these unmanaged areas will provide and support quality wildlife habitat. The objective of this study was to evaluate the forage production and stocking potential of an unmanaged wilderness area in east Texas. Four different community types were evaluated for forage yield, forage availability, and browse utilization for white-tailed deer. Results show that although a wide range of forage yields were measured in the spring, summer forage yield did not differ among the various communities. Availability also differed between community types, but utilization within each community appears to be lower than what could be supported

Cool Season Annual Forage Mixtures Trial

In 2015, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of five cool season annual forage species and five mixtures at Borderview Research Farm in Alburgh, VT. In the Northeast, cool season perennial grasses dominate the pastures and hay meadows farmers rely on throughout the season. In the fall, perennial pasture declines in yield and quality. The addition of cool season annual forages into the grazing system during this time, can help improve the quality and quantity of forage and potentially extend the grazing season. Recently, there has been a growing interest in utilizing multiple cool season forage species to maximize forage yield and quality. We compared five annual species alone and in three-and four-species mixtures to evaluate potential differences in forage production and quality. While the information presented can begin to describe the yield and quality performance of these forage mixtures in this region, it is important to note that the data represent results from only one season and one location

Taro leaf and stylo forage as protein sources for pigs in Laos

Existing forage plants may have applications as alternative protein resources for pigs in smallholder farming systems. This thesis examined the effect of harvesting/defoliation interval on the yield and chemical composition of taro leaves and stylo forage and analysed appropriate ensiling methods for these materials. The effect of replacing soybean crude protein (CP) with ensiled taro leaf and stylo forage CP on growth performance and carcass traits of LY (Landrace x Yorkshire) and ML (Moo Lath) pigs was also examined. Taro leaf and petiole dry matter (DM) yield increased with increased harvesting frequency in the two years studied, but there was no effect on tuber yield. The leaves contained 160-260 g CP kg¹ DM. Stylo leaf DM yield was unaffected by harvesting interval in the first year, while leaf DM yield was larger with the most frequent harvesting in the second year. The leaves contained 170-235 g CP kg¹ DM, which was much higher than in the stems or forage (leaves+stems). Use of cassava root meal, sugar cane molasses and taro tuber meal as silage additives affected pH and the DM, ash and NDF content of stylo forage and taro leaf silage, and the NH₃-N content of stylo forage silage. Level of additive affected pH and DM, NH₃-N, CP, ash and NDF content in taro silage, but not NH₃-N, CP and NDF content in stylo forage silage. Increasing duration of ensiling reduced pH and DM content in stylo forage and taro leaf silage. Dry matter intake (DMI) and CP intake (CPI) in growing LY and ML pigs were unaffected by increasing replacement (25 and 50%) of soybean CP by taro leaf silage CP in the diet, whilst for stylo forage silage DMI and CPI were highest when 25% of soybean CP was replaced. Average daily weight gain and feed conversion ratio (FCR), carcass weight, back fat thickness and dressing percentage were unaffected by increasing replacement of soybean CP with taro leaf or stylo forage CP in the diet. LY pigs had higher intake and better carcass traits than ML pigs. The work confirmed that stylo forage and taro leaves can be used as protein sources in smallholder pig production systems without negative effects on the performance of growing LY and ML pigs
