Over the last years a growing demand for ratite meat, including ostrich, emu, and rhea has been observed in the world. Ratite meat is recognised as a dietetic product because of low level of fat, high share of PUFA, favourable n6/n3 ratio, and higher amounts of iron content in comparison with beef and chicken meat. The abundance of bioactive compounds, e.g. PUFA, makes ratite meat highly susceptible to oxidation processes. Moreover, pH over 6 creates favourable environment for fast microbial growth during storage conditions affecting its shelf life. However, availability of information on ratite meat shelf life among consumers and industry is still limited. Thus, the aim of the present review is to provide current information about the effect of ratite meat packaging type, i.e. air packaging, vacuum packaging with skin pack, modified atmosphere packaging (MAP), on its shelf life quality during storage, including technological and nutritional properties.

In recent years a growing demand for ratite meat, including ostrich, emu, and rhea has been observed all over the world. However, consumers as well as the meat industry still have limited and scattered knowledge about this type of meat, especially in the case of emu and rhea. Thus, the aim of the present review is to provide information on technological and nutritional properties of ostrich, emu, and rhea meat, including carcass composition and yields, physicochemical characteristics, and nutritive value. Carcass yields and composition among ratites are comparable, with the exception of higher content of fat in emu. Ostrich, emu, and rhea meat is darker than beef and ratite meat acidification is closer to beef than to poultry. Ratite meat can be recognised as a dietetic product mainly because of its low level of fat, high content of polyunsaturated fatty acids (PUFA), favourable n6/n3 ratio, and high iron content in comparison with beef and chicken meat. Ratite meat is also rich in selenium, copper, vitamin B, and biologically active peptides such as creatine (emu) and anserine (ostrich), and has low content of sodium (ostrich). The abundance of bioactive compounds e.g. PUFA, makes ratite meat highly susceptible to oxidation and requires research concerning elaboration of innovative, intelligent packaging system for protection of nutritional and technological properties of this meat.

Infectious diseases caused by microorganisms are still a problem in Indonesia, both humans and animals. The problem of bacterial resistance to antibiotics has an impact on increasing morbidity, mortality, and health care. The problem of bacterial resistance to antibiotics has also been found in livestock, which can threaten human health. This situation has led many researchers to search for new bioactive compounds as alternative antibiotic candidates to fight multidrug resistant bacteria such as Mycobacterium tuberculosis, Staphylococcus spp., and Streptococcus spp. This study aimed to discuss and determine the development of endophytic bacteria isolated from several plants so we can know the role of endophytic bacteria in producing bioactive compounds, especially for application in veterinary medicine. Endophytic bacteria provide great potential to produce various new bioactive compounds obtained from secondary metabolite compounds from their host. Plants are one of the hosts for endophytic bacteria. Bioactive compounds from endophytic bacteria are widely used in health and veterinary applications as antibacterial, antiviral, anti-inflammatory, and antioxidant. This shows that endophytic bacteria can be a promising source of new antibiotics to overcome the problem of pathogenic bacterial resistance and disease in the world of animal health which also threatens human health. This review discusses some aspects in the phytochemistry of endophytic bacteria producing bioactive compounds and its application in veterinary medicine.
