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. © 2022, Ankara University.

AB  - Lameness is a multi-factorial condition that depends on managerial as well as genetic variables, but often is related to legs and feet condition of the animals. The aim of the study was to give an overview of legs and claws condition and the presence of lameness in sows at one industrial farm. Total 130 animals (90 dry i.e. pregnant and 40 lactating sows) were observed. The occurrence of leg joints swellings, than claws condition (toes length, dew claw condition, cracked wall) and lameness (in animals in group boxes) were visually recorded and then classified according to the appropriate protocols. Findings proved the occurrence of one or more of examined conditions in 40% of pregnant sows and in 45% sows in lactation. In more than 20% of pregnant sows lameness was presented. There was statistically significant positive correlation between the occurrence of lameness and leg swellings and between lameness and claw condition in pregnant sows (in both cases p lt 0.0001). The results show that lameness is a significant problem in the studied farm. In general, more attention should be given to monitoring of sows' physical condition and behaviour, to minimize the occurrence of welfare problems and to reduce production losses.
