Special Issue Information

Dear Colleagues,

Feed constitutes the largest share of livestock production costs, which highlights the need for proven feed management practices for monogastric animals (pigs and poultry). An effective livestock feeding strategy starts with the quality of feed ingredients. The content of energy, nutrients and anti-nutritional substances in feed raw materials and, consequently, in animal rations determines the results of rearing, the slaughter value and the quality of the products obtained. It is known that by appropriately selecting components for animals' food ration, we can influence the dietary value of meat or eggs. The appearance of new raw materials and feed additives requires the assessment of their nutritive value and usefulness in feeding a given animal species. Moreover, the effects of animal production may be the result of the interaction of nutritional and other factors.

This Special Issue focuses on the role that animal nutrients and feed management play in the modern nutrition of animals. For this reason, it welcomes high-quality studies on disparate feed and from their animal research fields including poultry, pigs, etc. Original research articles and reviews will be considered for publication in this Special Issue.

The study was conducted to evaluate the alternative to imported soybean meal—extruded soybean press cake—in feeding weaning pigs. The experiment was carried out with 20 35-day-old weaned pigs weighing about 8.8 kg, divided into 2 groups (10 pigs in each) differing in the main protein source: group I—control, solvent-extraction soybean meal, group II— extruded soybean press cake. The feed mixtures were iso-protein and iso-energetic. After 35 days of feeding, the pigs were slaughtered. The samples of blood, intestinal tissue and digesta, meat, and back fat were collected for analyses. Replacement of soybean meal with extruded soybean press cake in the weaners’ diet had no statistically significant effect on growth performance and feed utilization. Histomorphometry analysis of the intestines did not indicate any harmful changes. The soybean press cake did not affect the sum of volatile fatty acids in the large intestine, but the ammonia concentration was lower in the distal colon (p ≤ 0.05). It was found that the extruded soybean press cake in the feed significantly affected the fatty acid profile (p ≤ 0.05) of meat and back fat, increasing the amount of PUFAs; however, no negative impact on the durability of meat and back fat during storage was noted. In conclusion, the study confirmed the possibility of completely replacing solvent-extraction soybean meal with extruded soybean press cake in the feeding of weaned pigs. Full article
