The aim of the study was to overview the results of scientific research on the impact of feed additives used in broiler nutrition on breeding and meat quality. Selected additives used in feeding broilers with immunomodulatory properties, prebiotics and probiotics, herbs and herbal extracts and protein additives were characterised. The application of insects in poultry feeding as a good source of proteins and fat as a substitute of expensive feed rich in proteins was presented. Further research is needed on their nutritional value, levels of incorporation into diets and the performance of this feed ingredient. However, there are many challenges that need to be overcome by adoptingsuitable strategies to produce antibiotic-free broiler meat with regards to food safety and chickenwelfare issues. The additives available on the market should be used in accordance with the manufacturers’ recommendations and the grace period should be observed in order to obtain the expected production results and a high-quality product.

Buyers on eBay commonly rely on seller feedback ratings to determine bidding strategies.  Various studies have examined the impact of eBay’s reputation system on auction outcomes.  This study builds on prior research by examining the relationship between seller ratings on auction prices for two distinct product types, DVDs and designer watches and by benchmarking the bid prices against retail prices. The results show that eBay ratings explain a greater degree of price variation in Designer Watches than in DVDs.  The study also suggests that high quality product listings with such features as digital images, formatted pages, and product details may result in higher bid prices.

Accelerating the availability of COVID-19 vaccines is critical to preventing further waves and mitigating the impact on society. However, preparations for large-scale manufacturing, such as building production facilities, are typically delayed until a vaccine is proven safe and effective. This makes sense from a commercial perspective, but incurs great costs in terms of lives lost and damage to the economy. Several policy options are available to reduce this delay, all of which involve incentives or subsidies to invest in production facilities. We review existing approaches, then propose a novel alternative using “option-based guarantees” in which the government commits to paying a proportion of the manufacturer’s preparation costs should the product turn out not to be viable. Counterintuitively, this “payment for failure” is appropriate because in the case of success, a company makes a profit from the product itself, and does not need additional money from the government. While other approaches have critical roles, we argue that option-based guarantees are the most promising approach to ensuring a rapid vaccine for COVID-19. Compared to the alternative approaches, they reduce both costs to the government and risk to the companies, while maintaining an incentive to produce a high-quality product quickly and at scale.

EMPOWERMENT OF DUCK FARMERS GROUP THROUGH UTILIZATION OF RICE SNAILS AS ALTERNATIVE FEED FOR DUCKS IN CIHATEUP HAMLET, TASIKMALAYA. In Cihateup Hamlet, the presence of golden snail is abundant with a large number of paddy fields scattered in several locations. Moreover, the presence of golden snail in this area has the potential to be an agricultural pest so that to minimize its existence it needs to be used as an alternative to duck feed. The community service program aims to improve the insight and skills of members of livestock groups in utilizing and processing rice snails into quality food products. This community service method takes the form of counseling, training and mentoring for members of livestock groups. The target of this program is members of the livestock group “Kelompok Ternak Megar Bebek Cihateup”. The implementation of the community service program began in March to September 2017 in the Cihateup Hamlet, Sukanagalih Village, Rajapolah District, Tasikmalaya Regency. The impact of this program is to reduce the loss of rice farmers from rice snail pests and reduce the cost of feed for duck farmers. In addition, there has been an increase in the community's insight and skills in utilizing the region’s potential to become a useful and high-quality product.

SummaryTwo cases of livestock production involving French local breeds are analysed. The first shows how a high quality product under AOC (Protected Designation of Origin — PDO) has been defined for the Bresse chicken breed, formely kept by fancy breeders. The second shows the role of the local cattle breeds Abondance and Tarentaise in both the use of mountain areas and the development of PDO products. How to consider such values in a public policy dealing with farm animal genetic resources is discussed.

Abstract The presence of stems in cut tobacco is detrimental to cigarette quality, resulting in problems during production particularly on today's high-speed makers. Incomplete threshing and the use of unthreshed semi-Oriental tobaccos can increase the stem content in the cut tobacco considerably. The percentage of stems present in cut tobacco was investigated by HauniMaschinenbau AG specifically for semi-Oriental tobacco. Their findings show that not all stems present in the strips or lamina after cutting are classified as “objectionable”. However, the percentage of objectionable stems in the cut tobacco is not inconsiderable and depends on the thickness of the stems present. Reducing the objectionable stem contingent in cut tobacco is therefore a crucial concern of many cigarette manufacturers who set great store on ensuring high-quality product. HauniMaschinenbau AG offers a cut tobacco separator which has been specially designed for this purpose and also used as a cooler. A corresponding model is available in the HauniMaschinenbau AG pilot plant in Hamburg for tests using the customers’ own tobacco.

The results of the study of the influence of various concentrations of the complex bakery improver «Unipan Total» on the properties of semi-finished products and quality indicators of bakery products are presented. Bakery products were produced using the unpaired method according to a unified recipe for Dniprovskaya buns. To obtain a high-quality product, prototypes were prepared from wheat bakery flour of the highest grade with the addition of the «Unipan Total» improver at a concentration of 0,5 to 8% to the flour weight, control ones without the improver. Organoleptic and physicochemical indicators of the quality of wheat bread samples were determined by conventional methods.

The aim of this investigation was to develop a treatment for combined porcine blood corpuscle concentrate (BCC) and porcine collagenous connective tissue (rind) so as to make more use of these slaughter by-products as an ingredient in a high-quality product such as salami-type sausage. For this study, BCC was preserved, standardized (sBCC) (15% NaCl and 25% protein content), and then added (proportion of sBCC to rind, 15:85) to rind subjected to different treatments designated A, B, and C (A, 2 h at 90°C; B, 5 min at 90°C; and C, 2 h at 3°C). One half of each mixture was again heated (designated A1, B1, and C1; F70, ∼15), and the other half was only cooled (designated A2, B2, and C2). The now colored, highly proteinaceous rind mixtures (A1 to C2) were then cooled and granulated (designated GBR-A1 to GBR-C2). Three of the granulates (GBRA1, -B1, and -B2) proved to be promising new raw materials: their aerobic plate counts were <log 4.0 CFU/g, and their color was appealing (L* values, 23.9 to 25.9; a* values, 17.7 to 22.2; b* values, 11.5 to 12.7). These granulates were then substituted for part (5%) of the meat in the production of fermented raw salami-type sausages. Two of the sausages (SA1 and SB1) were microbiologically stable (containing mainly lactobacilli) and had positive sensory, chemical, and physical properties (e.g., protein, 21%; water activity, 0.90; pH, between 5.3 and 5.4 on day 36) meeting all standards for commercially produced raw sausages. Our investigation yielded a practicable way to treat and combine two slaughter by-products for use in a high-quality meat product.

In a principal-agent framework under moral hazard, when the monopolist can pass on the liability of any defect of the product to the subcontractors, and cannot credibly commit to a high level of investment, he actually chooses a low investment level and supplies a low quality product if the product replacement cost is below a critical level. However, under contract renegotiation, when the monopolist is taking the entire risk of replacing the defective product, he will profitably choose high investment level and serves high quality product. But the results show that the monopolist will choose to renegotiate the contract only for limited values of product replacement cost, even if renegotiation is socially optimal.
