Special Issue Information

Dear Colleagues,

The high costs of nutrition force farmers to consider optimal precision feeding, feed quality and feed digestibility. Therefore, ensuring the good quality of ingredients and feed additives is an indispensable element of modern animal nutrition. Feed additives which improve nutrient absorption could reduce the feeding cost and negative environmental impacts of farms. Ingredients and supplements dedicated to the early lives of animals can affect their long-term health and future growth performance. An increasing number of consumers are choosing foods that are beneficial to health, originating from animals fed with good-quality feed ingredients and natural feed additives that modify the quality of meat and other animal products. In this Special Issue, beyond the aforementioned issues, we are also interested in ingredients and additives which improve the growth performance and meat quality of animals exposed to heat stress, as well as those intended for companion animals.

This Special Issue is interested in research papers and reviews on all aspects related to the efficiency of feed ingredients and their effects on growth performance, carcass characteristics and meat quality. We invite you to share your recent findings in this Special Issue.

Beef is a dominant meat commodity produced mainly from beef cattle breeds. Dairy cattle breeds are reared for milk production, but their calves could be raised to produce high quality meat subject to designated feeding. The objective here was to investigate the role of oregano oil-enriched diets on the quality characteristics of meat produced by Holstein bulls. Fifty Holstein bulls, aged 12 ± 2 months and with an average weight of 365 ± 60 kg, were used. They were equally allocated in two experimental groups (n = 25). One group (group CON) was offered a basal diet and the other (group OREG) the same diet enriched with 50 mg/kg DM of oregano oil, for a period of 90 days. Afterwards, meat samples were subjected to microbiological (1 h after slaughter), physicochemical (1st and 15th day after slaughter), and sensory analyses (15th day after slaughter). The beef of group OREG is characterized with improved color parameters and a lower malondialdehyde (MDA) production rate and content (68.52 ng/g versus 105.91 ng/g, p = 0.01). The sensory evaluation of beef revealed higher scores for group OREG in flavor (3.88 versus 3.17, p = 0.0007) and color (3.87 versus 3.21, p = 0.001), as well as higher nutritional value, which was associated with significantly higher levels of alanine, arginine, aspartic acid, histidine, isoleucine, leucine, lysine, valine, and total amino acids (p < 0.05). Thus, the results suggest that the quality of the meat of Holstein bulls can be improved when they are fed a diet enriched with oregano oil. Full article
