AB  - The first few weeks after broilers hatch are the period of most intense bone growthand development, and the time when they are most susceptible to the in fluence ofvarious external and internal factors. Research in the recent decades has focused on theinvolvement of melatonin in bone development during early life in chickens. Melatoninrelease from the pineal gland has a circadian rhythm, with the highest levels circulatingduring the night and decreasing during the light phase of the day. Various types oflighting are used in intensive broiler production. In this study, the effects of melatoninon the tibial structure and growth of broilers were investigated. During the first twoweeks of life, two groups of chickens were kept under continuous light and fed thesame diet, with the experimental group receiving melatonin in the amount of 0.03 g/kg of feed. The results obtained showed that the addition of melatonin in the diet hadpositive effects on the development and growth of the tibia, which was expressed ina signi ficantly greater thickness of the diaphysis and cortical bone of the diaphysis,higher breaking force and higher values of alkaline phosphatase activity. The corticalbone mineral density of the tibia did not differ signi ficantly between the groups ofchicken.

AB  - Intensive broiler chicken production involves different lighting regimes, which affects a natural cycle of secretion of
melatonin, a hormone included in multiple physiological processes in a bird's body. This research aimed to determine the effects of
dietary melatonin supplementation during the first two weeks of broiler chickens' life, bred under constant 24 h lighting, on their health
and some hematological, biochemical, and production parameters. The study lasted 6 weeks. Three hundred and twenty 1-day chickens
were divided into two groups (control - C and experimental - M), with four replications and 40 chickens in each replica. In the first
two weeks (the first phase of the study), a continuous lighting mode 24L: 0D was applied. Group M was receiving a diet supplemented
with 30 mg/kg synthetic melatonin only during the first phase. Group C had a diet without melatonin supplementation throughout the
whole study. Melatonin addition had a statistically significant effect (P<0.01) on the mean values of body weight and daily weight gain
at the end of the 1st, 2nd, 3rd, 4th, 5th, and 6th week. The chickens of the experimental group have had a significantly higher value of the
European Production Efficiency Factor (EPEF) (P<0.05). The results presented in this paper indicate a direct benefit in stress relief in
broilers and a value of the organism's antioxidant system promotion, manifested by improved production performance and fattening
efficiency.

AB  - Meso je proizvod koji nastaje kroz različite biohemijske procese nakon
rigor mortis-a od skeletnih mišića životinje. Zbog toga karakteristike mišićnog
tkiva, njegova struktura, broj, prečnik i zastupljenost pojedinih tipova mišićnih
vlakana u velikoj meri određuju količinu i kvalitet mesa. Kako su selekcijom i
ishranom gotovo dostignuti maksimumi u proizvodnji mesa sa jedne strane, a sve
su veći zahtevi potrošača za “ekološkim” i proizvodima iz održive proizvodnje, uz
poštovanje principa dobrobiti životinja sa druge strane, ispitivanje uticaja fizičke
aktivnosti kod životinja dobija sve veći značaj, pri čemu se pod tom aktivnošću
podrazumeva ili slobodno kretanje životinja (na pašnjacima) ili poluslobodni
sistemi držanja različitog stepena intezivnosti. Takođe, ovaj faktor mogao bi biti
od značaja posebno kod svinja i živine, kod kojih je intenzivnom selekcijom na
mesnatost povećan broj glikolitičkih vlakana u mišićima, što je uslovilo i probleme
sa kvalitetom mesa (bledo, meko i vodnjikavo meso - BMV meso).
