“…This makes calendar days a variable and therefore inaccurate time scale. Few publications report forage DM accumulation as a function of GDD (see for instance Martini et al, 2009; Iannucci et al, 2015) and no previous research has, to our knowledge, linked the changes in nutritive value parameters with thermal units for modern oat cultivars.…”

Core Ideas• Oat forage harvested in late heading increases yield and milk production per hectare.• Oat cultivar Laker reached boot and heading 3-4 days earlier than ForagePlus.• Thermal units (GDD) should be used to report maturity time instead of calendar date. AbstractOat (Avena sativa L.) is a widely used forage crop in the USA and globally, often integrated in dairy systems where it provides the benefits of diversifying crop rotations. As the forage harvest occurs at a later date, forage yield is expected to increase while nutritive value is expected to decrease. To determine the optimal maturity stage to maximize milk production, a 2-year experiment with two forage-oat cultivars (ForagePlus and Laker) and four harvest times (boot stage, 2 days after boot stage, heading, and 5 days after heading) was established in a randomized complete block design with three replications at two locations in Wisconsin, USA. Laker reached the boot stage 4 days earlier and headed 3 days earlier than ForagePlus. Relative forage quality decreased at the same rate with increasing growing degree-days for both locations, years, and cultivars. Therefore, to maximize milk production per cow through feeding the highest nutritive value forage, harvesting oat at boot stage is recommended. Forage yield increased linearly with increasing growing degree-days for both locations, years, and cultivars, with steeper slope in Arlington than Madison due to precipitation differences. Model estimates of milk production per hectare in both cultivars increased linearly across the four harvest dates in Arlington. In Madison, milk production per hectare did not change significantly with harvest date. Harvesting oat for forage at late heading can therefore increase milk production per hectare, since the greater forage yield compensates for the reduction in forage nutritive value.

Abstract:Winter cereals are cultivated in order to produce grain for food and feed, green forage and haylage for cattle. The objectives of this study are to assay the production and chemical characteristics bromatological of winter cereal forages. The factorial arrangement of treatments 5 × 2 (5 cultivars and two cutting heights-low 7-10 cm and 20 cm from the soil surface) harvested when the grain was at the dough stage. Genetic materials tested were rye BRS Serrano, wheat BRS Umbu and BRS Pastoreio, triticale BRS Saturno, barley BRS Aliensa and Brevis oats BRS Centauro. The experimental design was a randomized complete block design with four replications. The assay carried out to forage, BRS Centauro showed oat forage yield higher than the other genotypes. Barley BRS Aliensa stood out for DMD (dry matter digestibility) and CP (crude protein) for the two tested cutting heights. BRS Pastoreio wheat had lower NDF (neutral detergent fiber) concentration than BRS Serrano rye.

“…On the other hand, oat are sown late in spring and the plants develop during the spring flush of other highly nutritious natural forage. Thus, while harvesting was at the end of summer for both crops, wheat was a less attractive food than oat after emergence of the oat plants and definitely after the stage of full grain development [40]. Therefore, the agronomic and phenological cycles of winter wheat expose it to deer feeding in winter and fall, while oat become a viable source of feed late in spring, when many other feed sources are available.…”

Interactions between a population of fallow deer (Dama dama), humans and crops in a managed composite temperate landscape in southern Sweden: Conflict or opportunity?

Landscapes composed of agricultural land mixed with forest are desirable since they provide a wide range of diversified ecosystem services, unlike specialized agricultural landscapes, but that creates a trade-off between these land uses since wildlife usually feed on crops and reduce yields. In Nordic countries, where human population density is low and game hunting can be a viable economic alternative, mixed landscape systems are particularly interesting. To evaluate the economic sustainability of such systems we need to quantify wildlife damage to crops. One important species, being popular among Swedish hunters and therefore economically valuable, is fallow deer ( Dama dama ). Our objective was to evaluate the economic sustainability of mixed landscape systems including cultivated fields and commercial hunting of fallow deer. We studied the effects of excluding fallow deer by using 86 exclosures and adjacent plots in winter wheat and oat fields in south-west Sweden. We analyzed yield losses and interactions between spatial and temporal grazing patterns, anthropogenic landscape features, and topological characteristics of the landscape. We found that animals avoided exposed spots, irrespective of distance from human activity. We also found a seasonal grazing pattern related to the different growing periods of winter wheat (more grazed, emerging in autumn) and spring oat (less grazed, emerging in spring). We then compared the costs of crop damage against the commercial value of fallow deer hunting. The damage amounted to 375 ±196 € ha -1 for wheat and 152 ±138 € ha -1 for oat, corresponding to a total cost per animal of 82.7 ±81.0 €, while each animal had an estimated market value of approximately 100 €. Therefore the value of fallow deer presence compensated for the associated cost of crop damage. Profit could be further improved in this case by adopting additional management strategies. In general our study confirmed the economic feasibility of this particular mixed land management.
