The processing of meat industry waste into meat-and-bone meal (MBM) provides the opportunity to use it as fertiliser in the cultivation of agricultural crops. This study was conducted in the years 2014–2017 at the Experimental Station in Tomaszkowo, Poland to assess MBM effects on yield and quality of maize cultivated for grain. An example of the effective use of nutrients contained in MBM applied at doses of 2.0 and 3.0 t ha is the cultivation of maize in 2016, which was affected by favourable weather conditions. The effect of the accumulation of MBM doses and, consequently, the provision of a greater amount of nutrients ensure sufficient amounts to obtain yields, greater than those provided by mineral fertilisation only. The macronutrient concentration in the maize grains following the application of MBM was similar to the composition of the grains of maize fertilised with mineral N, P and K fertilisers. With the MBM, micronutrients are introduced in amounts that are able to satisfy plants with these components, yet this study failed to demonstrate any effect of increased MBM doses on the concentration of the analysed elements in the maize grains.

The objective of the research was to estimate the microbiological quality of feed and fodder components for the occurrence of Salmonella produced in the area monitored by the Department of Veterinary Hygiene in Olsztyn in the period 2010–2015. The compilation was prepared on the basis on the data of the Department of Veterinary Hygiene in Olsztyn. The research was performed according to the requirements of Polish Standard PN-EN ISO 6579. In the Warmia and Mazury Provinces in the period 2010–2015, 6 109 fodder samples were tested. 54 samples gave positive results, which accounted for 0.88%. In 2010, 1 537 samples were tested. Whereas in the years: 2011, 2012, 2013, 2014 and 2015 the number of samples tested was, consecutively: 1 187; 950; 1 304; 659 and 472. At this time, the most contaminated feed materials were rapeseed meal, which accounted for 5.81%. This feed material has had the highest degree of fodder contamination with Salmonella, and is represented as a good substrate for the development of bacteria. Afterwards, fishmeal was contaminated for 3.13% and soybean meal – 3.02%. The rarest contaminated materials for fodder production was meat and bone meal (0.28%). The results from the area monitored by the Department of Veterinary Hygiene in Olsztyn are similar to the levels of contamination reported in other years in the Warmia and Mazury. Technological advances and increasingly stringent control systems make it possible to reduce the degree of contamination of feed with Salmonella. However, it needs to be remembered that Salmonella is common in the environment. The bacteria has a high ability for survival. It is not possible for it to be completely eliminated.

A comprehensive study of feed staff of animal origin was carried out to identify the most efficient ways of the use as components of compound feeds. In the samples of feeds (fish meal, fish extrudate, meat and bone meal), parameters of nutritional value and safety were determined. It was found that the most stable content of crude protein and essential critical amino acids was characteristic of fish meal, which is advisable to be used for the purpose of balancing compound feed for young animals in protein and lysine.

Hydrothermal carbonization is one of suitable methods for energy recovery of sewage sludge and meat and bone meal. The task of the article is to determine appropriate hydrothermal carbonization process conditions and their impact on the quality of the final product – so called biochar or hydrochar. Parameters of the two main phases – initiation and polymerization – were monitored. The basic fuel properties of the final solid products of hydrothermal carbonization were determined. To produce biochar by hydrothermal carbonization, multifunctional pressure vessel with accessories was used – a batch reactor BR-300. Process parameters of hydrothermal carbonization confirm the effect of increasing temperature to increase the lower heating value (LHV). Neither calorific values of meat and bone meal (17.22 MJ/kg), nor calorific values of digested stabilized sludge (12.14 MJ/kg) showed a significant increase after undergoing processing. The effect of reaction temperature on the LHV of the final product is significantly higher than that of residence time. The results show that the main factor affecting LHV of the fuel sample is the final amount of ash. Unlike the meat and bone the hydrothermal carbonization of the stabilized wastewater sludge is one of the effective processing methods for subsequent energy use.

Variation in the apparent ileal digestibility of amino acids in 19 meat and bone meal samples, obtained from commercial rendering plants in New Zealand, was determined using 5-week-old broilers. Assay diets contained meat and bone meal as the only source of protein, and chromic oxide as an indigestible marker for the calculation of amino acid digestibility values. Correlations of chemical composition (crude protein, ash, crude fat, and gross energy) and in vitro assays (protein solubility in 0.2% potassium hydroxide and nitrogen digestibility by 0.2% pepsin hydrolysis) with ileal amino acid digestibility were also examined. Considerable variation was observed in the contents of crude protein (38.5–67.2 g/100 g), ash (13.0– 56.5 g/100 g), crude fat (4.3–15.3 g/ 100�g), and gross energy (9.4–22.3 MJ/kg) of meat and bone meal samples. The amino acid concentrations and ileal digestibility of amino acids also varied substantially. Cystine, the first limiting amino acid in meat and bone meal, had the lowest digestibility estimates. Correlation analyses showed that the ash content was the only chemical parameter that was consistently correlated with amino acid digestibility. Digestibility of amino acids, with the exception of aspartic acid, threonine, serine, tyrosine, histidine, and cystine, was negatively correlated with ash content, with samples with high ash levels having lower digestibility. Both in vitro assay measurements were found to be insensitive indicators of variations in amino acid digestibility.
