Article Synopsis
- Beef is primarily produced from beef cattle, but dairy calves can also be raised for meat; this study focuses on how oregano oil in diets affects meat quality in Holstein bulls.
- A total of 50 Holstein bulls were split into two groups: one received a standard diet, while the other’s diet was enriched with oregano oil for 90 days.
- The results showed that the oregano oil group had better meat color and flavor scores, lower malondialdehyde levels, and higher nutritional value, indicating that oregano oil can enhance the quality of meat from Holstein bulls.
Maintaining respiratory tract health is crucial for layers, impacting gut health, laying performance, and egg quality. Viral diseases and standard vaccinations can compromise tracheal epithelium function, leading to oxidative stress. This study assessed the impact of a blend of feed additives, predominantly lysozyme (L), essential oils (EO), and vitamins (VIT) (referred to as L + EO + VIT), on young layers during an oral vaccination schedule.

Milk production and fertility traits were investigated. A total of 330 animals were allocated into two groups, treated ( = 176) and control ( = 154).

- The study examined how replacing half of the soybean meal in dairy cow diets with flaxseed and lupins affects milk and cheese production.
- Both groups of cows had similar milk yields, but the FL group produced milk with more beneficial fatty acids and lower protein carbonyls compared to the control group.
- The resulting white cheese from the FL diet had a healthier fatty acid profile and maintained similar taste and texture characteristics to the cheese from the control group.
The demand for ovine milk and ovine dairy products is constantly increasing due to their exceptional sensorial characteristics and their health benefits for consumers. However, dairy fat content and composition are of particular concern for consumers as well as the medical community, as there are risk factors for coronary disease, diabetes mellitus, cancer, and other serious diseases. For this reason, attempts have been made to control/regulate the fat composition of ovine milk by modifying sheep dietary intake of polyunsaturated fatty acids.

Plant secondary metabolites may alleviate effects, partly due to their antioxidant activities. Herein, we investigated the effects of dietary supplementation with a phytonutrient solution (PHYTO) consisting of a plant extract combination of and on young layers (25-32 wk of age) raised under naturally elevated temperature conditions.
