The final phase in pork production is the transport of finisher pigs to the slaughterhouse. Fasting is one of the parameters that influence the stress coping ability of the pigs during transport and lairage. When implemented correctly with attention to the local factors, pre-slaughter fasting can improve animal welfare, pathogen risk and carcass hygiene. The length of pre-slaughter feed withdrawal time is important to the success of the production practice. In practice, a fasting time before slaughter between 12 and 18 h enhances pork safety, pork quality, and animal welfare. This means that communication between producer and slaughterhouse is essential when planning the fasting and lairage times to avoid carcass and technological pork quality problems (such as pale, soft, and exudative (PSE) meat or dark, firm and dry (DFD) meat).

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

In two experiments, individually weighed male broiler chickens were held without feed in either conventional transporting crates or litter floor pens. These latter birds received water ad libitum and were given constant light. At regular intervals, 12 of the crated or 10 of the penned birds were killed and the section of the proximal alimentary tract containing feed residue recorded. Carcass yield and water uptake after 2 h immersion in running water at 4 °C was also recorded. Feed residue did not pass through the tract of birds held in crates, since approximately 70% of these birds had feed in their gizzard after 16 h. Holding in pens resulted in a progressive emptying of the gut, such that after 12 h the upper tract was evacuated. Less shrink was observed for birds held in pens, which might be explained by the birds having access to water. It is concluded that the alimentary tract of birds cannot effectively be cleared of feed when birds are held in crates. Thus the time birds spend in transport should not be included in calculating time of feed withdrawal.

Amid high-profile food scares, health concerns and threats of information imperfection and asymmetry, the Chinese pork industry faces increasing demands from consumers for assurances regarding quality and production methods in both the domestic and export markets. Using a real choice experiment (RCE), 316 consumers in Wuxi, located in China’s Jiangsu Province, were randomly surveyed to examine the impact of various factors (e.g., traceability, lean meat essence testing, animal welfare, appearance, and price) on consumers’ preference and willingness to pay (WTP) for pork products. A random parameter logit model was estimated, and the results show that having a traceable code is the second important factor after price for consumers, corresponding to a WTP of 4.76 yuan per catty, followed by a bright red appearance, a national stocking density standard of animal welfare, and detected no lean meat essence, corresponding to a WTP of more than 2 yuan per catty. In addition, there is a complementary interrelationship between a traceable code and a bright red appearance, detected no lean meat essence, and a national stocking density standard of animal welfare. The results concerning the latent class model (LCM) indicate that 56.9% of consumers are “quality-focused” consumers who are willing to pay a high price for traceable code, detected no lean meat essence, a national stocking density standard of animal welfare, and bright red appearance attributes. A further 28.1% are “price-sensitive” consumers who pay significant attention to the price, and the price that they pay for each product is meagre. The consumers with “preference combination attributes” attach greater value to interaction attributes, such as a traceable code combined with detected no lean meat essence or a bright red appearance and detected no lean meat essence combined with a national stocking density standard of animal welfare or a bright red appearance, accounting for 15% of consumers. The government should improve the traceability system, increase the intensity of lean meat essence testing, promote the welfare level of pigs, and promote public education and publicity on pork quality and safety attributes. Meanwhile, enterprises can formulate “differentiated” pork products, according to different consumer groups, and appropriately increase prices, according to production costs, in order to meet the requirements for pork quality and safety for consumers.
