“…No oeste do Paraná algumas propriedades se destacam na produção de feno de Tifton 85 , porém os fenos e Aveia Preta (CASTAGNARA et al, 2012a), Azevém (NERES et al, 2011) e Alfafa (NERES et al, 2010) são menos usuais. Da mesma forma, o Capim Sudão (Sorghum bicolor), cv.…”

“…Bertol et al, (2004) suggest that the effects of no-tillage cropping systems involving winter crops should manifest themselves after several years of adoption. However, the presence of plants and their root system can minimize the possible impacts to be caused by trampling of animals (Castagnara et al, 2012), result evidenced in this work, since all plots contained plants, even spontaneous on the fallow plots.…”

“…For the 0.05-0.1 m layer, seeding density influenced the total porosity, and the lowest sowing density (40 kg ha (Table 1). This result may have been caused by the root system of oats, since, according to Bertol et al (2000) in the ICLS the presence of roots of forage grasses improves the structure of the soil, mitigating the impact of trampling, through the root renovation (Castagnara et al, 2012). In addition, we have a dual purpose: crops are stimulated to develop the root system when grazed.…”

“…The cultivation of oat, whether single or consortium in integrated crop-livestock system (ICLS), is a technically and economically viable alternative used by farmers in the winter period in the south of Brazil. This cultivation makes it possible to obtain high-quality forage for animal feed, as well as straw to cover the soil for sowing summer crops under no-tillage system with good quality (Castagnara et al, 2012). However, in areas where ICLS is used, inadequate oat crop management may result in lower straw production for soil protection and no-tillage of crops in succession (Demétrio et al, 2012) which may contribute to a decrease in productivity.…”

The objective of this study was to evaluate the effect of two sowing densities of oat crop, managed in an integrated crop-livestock system (ICLS), or the use of fallow during the winter period, on the soil physical properties, total carbon and soil carbon stock, in two years. A split-plot in a randomized block design, with additional treatment was used. It was found that the number of grazing in the year 2014 adversely affected the values of macroporosity and microporosity in the layer 0-0.05 m, besides the microporosity in the 0.1-0.2 m layer. The total porosity in the 0.1-0.2 m layer was positively influenced by the sowing density of oats only in the year 2014. The soil penetrometer resistance (SPR) had changes after winter 2015, at 0-0.05 m due to the number of grazing. During 2014, there were no changes in the total carbon and carbon storage of the soil. In 2015, the amount of grazing used, negatively affected the total carbon in layers 0-0.05 and 0.1-0.2 m. However, it positively affected the storage of carbon in soil in the layer 0.05-0.1 m. The adoption of the lower density of the oat crop with realization of a grazing tends to improve the physical properties, total carbon and soil carbon stocks.

“…In the semiarid climates, for animals to maintain an appropriate level of production throughout the year, highquality roughages must also be provided during the dry season, since the demand for feed is present all year long. Among the typical forage-preservation methods, haying is a process aimed at rapidly drying the material to prevent losses of carbohydrates and leaves; for this reason, the plant should ideally have fine stems so that its drying time is reduced (Castagnara et al, 2012).…”

Substitution of soybean meal for urea in diets based on deferred buffelgrass hay for feedlot sheep

et al. 2018

The objective of this study was to evaluate the effect of substituting soybean meal for urea in diets based on deferred buffelgrass on the performance of feedlot sheep. Thirty mixed-breed sheep with an average initial body weight of 17±1.5 kg were distributed in a completely randomized design in which the experimental treatments consisted of five diets with six replicates. Diets were composed of deferred buffelgrass plus concentrates and calculated to be isoproteic. Treatments were represented by the substitution of soybean meal for the urea levels (0, 25, 50, 75, and 100%). Nutrient intake did not differ among animals fed diets with urea levels. Hot and cold carcass weights, hot and cold carcass dressing percentages, initial and final pH, and weight of commercial cuts did not differ among animal fed diets with urea levels. There was no difference for non-carcass components among animals, except for the empty carcass, gall bladder, and perirenal fat weights, which were influenced by dietary urea levels. Substituting the crude protein from soybean meal for the protein from urea provides a similar performance in sheep consuming deferred buffelgrass.
