By 2020, Dutch dairy chains envisage to be self-sufficient with regard to energy used by dairy farms and dairy processors. This would require dairy farms to produce 25 PJ per year, possibly by a combination of wind, solar and biogas. Current analyses focus on biogas. To evaluate the project’s feasibility we estimated the expected technical and financial performance of 4 types of business models, i.e. “CHP-farm”, “CHP-large”, “green gas” and “central upgrading”. Data stem among others from 23 biogas plants in the Netherlands. Anticipating that CHP-models and green gas models occur with a likelihood of 40% and 60% respectively, the total number of biogas plants at dairy farms would amount to 463. There would however be an expected deficit of Euro 157 million... |

By 2020, Dutch dairy chains envisage to be self‐sufficient with regard to energy used by dairy farms and dairy processors. This would require dairy farms to produce 25 PJ per year, possibly by a combination of wind, solar and biogas. This paper focuses on biogas. To evaluate the project’s viability we estimated the expected technical and financial performance of 4 types of business models, i.e. “CHP‐farm”, “CHP‐large”, “green gas” and “central upgrading of green gas”. Data stem from among others 23 biogas plants in the Netherlands. Anticipating that CHPmodels and green gas models occur with a likelihood of 40% and 60% respectively, the total number of biogas plants would amount to 232 (1% of dairy farms), including a total of 5 million tons of manure per... |

Abstract In this study, the live performance and costs of broiler production was examined and cost analysis were assessed in the Balıkesir, Bolu and Sakarya Provinces, which are the most important broiler-producing regions of Turkey. Annual (years 2012-2013) production data of 125 broiler farms were analyzed. Farms were scaled according to the irrearing capacities as small (1-10,000 broilers), medium (10,001-30,000) and large (30,001 and above). Cost and performance differences among farm scales and research centers were tested by one-way analysis of variance. Average live weight (LW), livability (LA), slaughter age (SA), feed conversion ratio (FCR), and production efficiency factor (PEF) values were calculated as 2.436 ± 0.006 kg; 93.502 ± 0.133%; 42.293... |

ABSTRACT Biological nitrogen fixation (BNF) efficiency can be increased by co-inoculation with bradyrhizobia and Azospirillum brasilense, allowing even greater uptake of water and nutrients, leading to higher yields. Thus, this study aimed to evaluate the technical and economic viability of soybean in the Cerrado, according to the cultivars and co-inoculation with Azospirillum brasilense. The experiment was conducted in Selvíria, MS, in no-tillage system, in Oxisol, arranged in a randomized block design in a 2 x 2 factorial scheme with two cultivars (‘Potência’ and ‘Valiosa’), with and without co-inoculation with Azospirillum brasilense in the seed. Co-inoculation with A. brasilense increases grain yield in the cultivars ‘Potência’ and ‘Valiosa’, being... |
