AbstractPopulation growth and rising incomes have led to increasing global demand for meat products. Meeting this demand without converting remaining natural ecosystems or further degrading ecosystems is one of the largest global sustainability challenges. A critical step to overcoming this challenge is to increase the productivity of livestock grazing systems, which occupy the largest land area of any type of agriculture globally. Integrated crop−livestock systems (iCL), which re-couple crop and livestock production at the farm scale, have been considered a promising strategy to tackle this challenge by restoring degraded pasturelands and providing supplemental nutrition to livestock. However, few studies have analyzed the economic viability of such systems, especially in Brazil, an important player in global food systems. This paper presents an economic analysis of iCL in Mato Grosso, Brazil, the largest grain and beef producer in the country, which spans the ecologically diverse Amazon, Cerrado and Pantanal biomes. We compare the economic performance of an integrated soybean/corn and beef cattle system to a continuous crop (soybean/corn) system and a continuous livestock (beef cattle) production system from 2005 to 2012. We use empirical case study data to characterize a ‘typical’ farm for each production system within the study region. We find that the integrated crop−livestock system has a higher annual net present value (NPV) per hectare (ha) than continuous cropping or livestock under a range of discount rates. However, under a scenario of substantially higher crop prices, the continuous cropping outperforms iCL. While iCL is not feasible in all regions of the Amazon and Cerrado, our results indicate that in places where the biophysical and market conditions are suitable for production, it could be a highly profitable way to intensify cattle production and potentially spare land for other uses, including conservation. Nevertheless, additional credit and technical support may be needed to overcome high upfront costs and informational barriers to increase iCL areas as a sustainable development strategy for agriculture in the Amazon and Cerrado regions.

Abstract: The present study evaluates the economic viability of four different models of beef cattle production in the rio Vermelho hydrographic basin. The study focuses on the traditional extensive ranching system, which was compared to three intensive systems, one based on low levels of concentrated supplementation, a second with low levels of concentrated supplementation and confinement for fattening and an intensive grazing system, with supplementation during the dry and rainy seasons. The investments were estimated for the different levels of technical specifications of each system. The net present values and internal return rate were used for the assessment of the economic viability of the project, considering the minimum rate of attractiveness, equivalent to the inflation-adjusted savings interest rate (6.17%). The continuity of the sector was evaluated based on the gross and net margins, and profitability rates, where the system is already installed. All four systems had gross and net margins and profitability consistent with their economic sustainability over both the short and long terms. However, only two systems (reduced consumption of concentrated supplements and the intensive grazing system) were economically viable as start-ups.

Abstract This study aimed to assess the performance of intact and castrated beef cattle on the pasture of Brachiaria humidicola alone and intercropped with Arachis pintoi cv. BRS Mandobi. The experiment was carried out from February to June 2016 on the private property of a partner of Embrapa Acre. The experimental design was completely randomized in a 2×2 factorial arrangement, with two sex classes (intact and castrated) and two types of pasture (alone and intercropped). The leaf to stem ratio was high (P<0.05) in the pasture alone. No significant difference was found for stocking rates. Dry matter intake was high (P<0.05) in the intercropped pasture compared to that alone, with means of 8.96 and 6.66 kg/ day, respectively. Animals managed in intercropped pastures had better performance (P<0.05) than those castrated under pasture alone. Nelore steers castrated at 20 months of age, managed under intercropped pastures, showed similar productive performance (P>0.05) to intact animals.

The supplementary irrigation is an alternative to ensure forage production and quality in periods with irregular rainfall, however, is necessary to know the irrigation economic viability in order to maximize profits. The study was performed in Santa Maria, Rio Grande do Sul State in southern Brazil, during 2015/2016 and 2016/2017 agricultural years, aiming to evaluate the sudan grass economic viability under different irrigation depths, in order to define which irrigation depth (0, 25, 50, 75, 100 and 125% of the reference evapotranspiration-ETo) has the highest net revenue. Forage production functions were generated and allowed to establish the carrying capacity and production costs related to each applied irrigation depth. The forage supply was 4% of the liveweight, animals with 300 kg were considered, and average daily liveweight (LW) gains of 0.5, 1.0 and 1.5 kg LW day-1 were simulated for the conversion of dry mass production in liveweight gain per hectare. Gross revenue was determined considering the price of R$ 6.50 per kilogram of liveweight. The production costs were divided into fixed and variable, related and not related to irrigation. The conventional sprinkler irrigation was economically viable for the sudan grass cultivation for beef cattle production, with the highest net revenue for the irrigation depth of 100% of ETo, in both years. However, the animals feed conversion is the determinant factor in net revenue because it represents the greatest profits variation source.

Abstract: The objective of this work was to evaluate the inclusion of sunflower cake (SC) and the addition of enzymes in the ration of lightweight replacement pullets in the growth phase, as well as their effects on the variables feed consumption and conversion, productive performance, sexual maturity, egg quality at the beginning of the laying phase, and economic viability. Five hundred and forty pullets of the Hy-Line W-36 light line were used. The experimental design was completely randomized, in a 2×2+1 factorial arrangement, with two inclusion levels of SC (10 and 20%), with or without the addition of enzymes, and a control treatment. At the end of the growth phase (7 to 17 weeks age), 360 birds were transferred to the laying shed until their thirty-fifth week of age. There was no interaction between SC levels and enzymes, but an isolated effect of rations and enzymes was observed on feed consumption and conversion. There was a decrease in specific egg density and an interaction between the factors for this variable, but without affecting productive performance. The inclusion of up to 20% SC in the rations does not affect bird performance in both evaluated phases; however the use of 20% SC with enzymes is more economically viable.

Abstract The Indonesian Beef Cattle Research Station (BCRS) has undertaken conservation and improvement of Grati-Ongole crossbred cattle (POGASI Agrinak) by distributing selected cattle into some provinces in Indonesia. This study aimed to evaluate the productive performance of the calves born in different agroecological zones. Sixty-seven male and female POGASI Agrinak were distributed in Indonesia including in upland (e.g., in 50 Kota, Payakumbuh, one bull, and nine cows and Pule, Trenggalek, one bull, and eight cows) and in low land (e.g., in Jember, one bull and six cows, Indramayu, one bull and six cows, Situbondo, 25 bulls and Tanahlaut, South Kalimantan, ten bulls). The cattle were kept under diverse environmental and management systems. The natural mating system was applied in communal pens using selected bulls. The parameters observed were the number of calves and the birth weight. It resulted in 168 calves born in the upland and five calves born in low land. While the birth weight of calves born in lowland and upland was 25.8 + 1.6 kg and 25.2 + 2.4 kg respectively. Meanwhile, the birth weight of calves in BCRS was 25.3 + 25 kg. To conclude, the birth weight both in BCRS and in those sites’ ex-situ was comparable.

The aim of the present study was to evaluate the effects of feeding faba bean and sweet lupin as alternative protein sources to soybean on productive performance, blood parameters, carcass composition, and chemical-physical characteristics of meat and its fatty acid (FA) profile in Charolais heifers. Twenty-four heifers were divided into three homogenous groups and fed with durum wheat straw and three iso-energetic and isonitrogenous pelleted complete diets containing 14% (on as-fed basis) soybean meal; 28% faba bean; and 20% sweet lupin seed. The animals were slaughtered after a 168 day feeding period, and the Longissimus lumborum muscle was sampled for meat quality measurements. The feed conversion index was better in the heifers fed faba bean compared with the soybean treatment group (6.71 versus 7.17). No differences were found among treatment groups in productive performance, slaughtering data and physical features. The concentration of linoleic acid in the meat of the soybean group differed significantly from that in the lupin group (2.38 versus 2.11%). Feeding lupin seed increased the concentrations of C20:3 n-6 (0.09%) and C20:4 n-6 (0.20%) in meat significantly, compared with the soya- and faba bean treatments (0.06–0.07% and 0.12–0.13%, respectively). No differences were found among groups for blood parameters, except for urea concentration, which was lower in the lupin group compared with the concentrations in the serum of heifers receiving the soya bean treatment (31.29 as opposed to 37.56 mg/dL). In conclusion, since faba bean and lupin seed did not affect any of the parameters negatively, these legume grains can be included successfully as alternative protein sources in beef cattle diet.Keywords: Faba bean, lupin seed, soybean, beef cattle, feeding
