ABSTRACT: Broiler chicken welfare regulation at farm level is scarce in Brazil. This research aimed to study good agricultural practices at farm level adopted by broiler chicken companies in the state of Paraná, analyzing them in relation to the promotion of animal welfare. Twenty exporting companies were contacted, 15 answered the questionnaire. The participating companies were responsible for 76.3% of the State broiler production. Indicators related to the availability and the quality of food and water are being adapted by the companies, but still need to be improved. Regarding environmental indicators, companies had concerns about air and litter quality and about the implementation of emergency systems on totally enclosed broiler houses. Natural light has been replaced by low intensity artificial lighting. Footpad dermatitis was the most cited disease used as a sanitary indicator (93.3%), but little information was given about the maximum percentages allowed. Environmental enrichment is not used in poultry houses. This study identified agricultural programs with positive and negative impacts on animal welfare. Investments on research seem to be the only way to conduct changes on broiler chicken chain without reducing the quality of animals' life.

<p>Gedong gincu mango is a specific mango variety in West Java Province, which has a high economic value and the prospect of being a superior export commodity of Indonesia. Despite its increasing production and high market prospect, gedong gincu mango agribusiness still faces various problems, both in on-farm and off-farm aspects. This paper aims to study the agribusiness of gedong gincu mango, covering both on-farm and off-farm aspects and export prospects. In general, gedong gincu mango farmers are small-scale farmers who practice traditional cultivation, harvest, and post-harvest management; are not yet market-oriented; practicing conventional marketing that relies on collecting traders, and have weak institutional. These conditions cause low productivity and diverse quality of gedong mango and are not continuously available throughout the year, which hinder the potential for wide-open exports from being appropriately utilized. It needs improvement in both on-farm and off-farm to improve the production and marketing of gedong gincu mango. At the on-farm level, efforts to increase competitiveness can be made by improving fruit production, productivity, quality, and continuity, by applying good agricultural practices. At the off-farm level, this can be done through improving facilities and infrastructures, institutions, and regulations. These efforts should involve all parties, including farmers (producers), marketing agents (collectors, traders, exporters), and policymakers.</p>

The Food Safety on the Farm series is a collection that reviews the generally recognized principles of GAPs (good agricultural practices) as they relate to produce, primarily at the farm level and with a particular focus on fresh Florida crops and practices. This publication focuses on GAPs and GHPs (good handling practices) relating specifically to sanitary facilities. Written by Jessica A. Lepper, Aswathy Sreedharan, Renee M. Goodrich-Schneider, and Keith R. Schneider and published by the UF/IFAS Food Science and Human Nutrition Department, January 2018. http://edis.ifas.ufl.edu/fs159

Good agricultural practices (GAPs) and good handling practices (GHPs) encompass the general procedures that growers, packers and processors of fresh fruits and vegetables should follow to ensure the safety of their product. GAPs usually deal with preharvest practices (i.e., in the field), while GHPs cover postharvest practices, including packing, storage and shipping. This factsheet covers GAPs relating to packing operation sanitation. There are seven other Florida Cooperative Extension factsheets in the ‘Food Safety on the Farm’ series that focus on specific aspects of the GAPs program and how they relate to Florida crops and practices. Under the new Food Safety Modernization Act (FSMA), GAPs are a foundation of the Produce Safety Rule (PSR). Other than for round tomatoes in Florida (T-GAPs regulation), GAPs have mainly been a voluntary program. Additionally the PSR mandates all non-exempt operations to follow these new FSMA federal guidelines (6), but all exempt commodities and for those producers exporting to foreign countries, GAPs may still be required. Both the mandatory PSR and GAPs aim to reduce the foodborne illness burden associated with produce.

Aim. The comparison of the effect of hydrothermal conditions and various agricultural practices on the emission of CO 2 from chernozems in the Left-Bank Forest-Steppe of Ukraine. Methods. The dynamics of the intensity of carbon dioxide emissions from chernozem calcic (typical chernozem – in Ukrainian classifi cation) was studied during the growing season of 2011–2012. The observations were based on two fi eld experiments with various methods of soil till- age (6–7 years from the beginning of the experiment) and fertilization systems (21–22 years from the beginning of the experiment). Particularly, plowing at 20–22 cm, disking at 10–12 cm, cultivation at 6–8 cm and direct seeding using Great Plains drill were studied among the soil tillage methods. Mineral system (N 45 P 50 K 45 ), organic system (manure 8 t/ha) and combined organic-mineral system (manure 8 t/ha + N 45 P 50 K 45 ) were studied among fertilization systems. The intensity of CO 2 fl ux was determined using the non-stationary respiratory chambers by the alkaline absorption method, with averaging of the results during the day and the frequency of once a month. Results. During the warm period, the emission of carbon dioxide from the soil changes dynamically depending on temperature and humidity. The maximum of emission coincides with the periods of warm summer showers in June-July, the minimum values are characteristic for the late autumn period. The total emission losses of carbon in chernozems over the vegetation period ranged from 480 to 910 kg/ha and varied depending on the methods of tillage ± (4.0–6.0) % and fertilization systems ± (3.8–7.1) %. The changes in the intensity of CO 2 emission from the soil under different methods of soil tillage are associated with hydrothermal regime and the depth of crop residues location. The biggest difference is observed im- mediately after tillage, but in the spring period the differences are only 12–25 %, and after drying of the top layer of soil become even less. Direct seeding technology provides the greatest emission of CO 2 from chernozem, which is fa- cilitated by better water regime and more complete mineralization of plant residues on the soil surface. Annual losses of carbon are the least under disking of soil at 10–12 cm. The changes in the intensity of CO 2 emission from the soil under different fertilization systems are associated with the involvement of the additional organic matter from plant residues and manure to the microbiological decomposition. The greatest emission was observed under the organic- mineral fertilization system, which increased the loss of carbon by 7–8 % in comparison with the mineral system in the unfavorable hydrothermal year and by 11–15 % in the more favorable year. These differences are observed mainly during the fi rst half of the growing season when there is a clear tendency to increase the intensity of soil respiration. Conclusions. The hydrothermal conditions of the warm period of the year are decisive in the formation of the CO 2 emission fl ow from chernozems. Due to the improvement of agricultural practices, emissions might be reduced but not more that by 15 % of natural factor contribution.
