AB  - The broiler production faces many challenges, which can cause negative
effects on their health and welfare. The great importance for farmers is to prevent
disease outbreaks, and biosecurity measures are very significant. This study aimed
to quantify the level of biosecurity measures in broiler farms of different capacities,
using a standardized procedure, and to identify key aspects that would require
improvements. The research was conducted from May to September 2022, and 15
randomly selected broiler farms participated. Five large-size (>30,000 chickens),
five middle-size (10,000-30,000 chickens) and five small-size farms (<10,000
chickens) were analyzed. All farms are located in Vojvodina and farmers agreed to
participate in the survey. The Biocheck.UGent scoring system
(https://biocheckgent.com/en) was used to quantify biosecurity measures. The
overall farm biosecurity is a weighted average of the external and internal
biosecurity. Our results showed a low level of implementation of internal and
external biosecurity measures on all farms (40-63%). The overall rating of
biosecurity on farms was lower than the world and country's average. The results of
this study suggest that the control of implemented biosecurity measures in broiler
farms is very important. Most of the biosecurity risks for broiler farms originate
from inappropriate site selection, purchase of day-old chicks of unknown quality,
lack of procedures, and training of farm employees. This study should provide a
good encouragement for the development of a biosecurity plan, identifying risks
and the appropriate way to educate farm

AB  - This experiment was performed to investigate the protective effect of a new combined adsorbent (bentonite + yeast cell 
wall extract) previously tested in vitro, on the occurrence of pathological lesions in broilers fed a diet contaminated with aflatoxin
B1 until 21 days of age. A total of 96 one-day old Ross 308 hybrid broiler chickens were divided into four groups: group I (control),
group II (5 g/kg adsorbent), group III (5 g/kg adsorbent + 2  mg/kg aflatoxin B1), and group IV (2 mg/kg aflatoxin B1). Grossly,
AFB1 and AFB1+adsorbent fed birds showed enlargement, friable texture of liver and enlargement and pallorness of kidneys. Spleen
revealed size reduction. No gross-pathological changes were observed in control and group II. Histopathologically, lesions were
observed in aflatoxicated groups. Liver revealed vacuolar cell degeneration, periportal and perivascular infiltration of mononuclear
cells. Kidneys revealed mild to moderate degree of haemorrhages, tubular epithelial necrosis and infiltration of mononuclear
cells along with heterophils. In group IV, catarrhal enteritis characterized by desquamation of epithelial cells were found in the
duodenum. A milder form of gross and histopathological lesions was seen in group III. In conclusion, the present study revealed
that supplementation of a new combined toxin binder product in the concentration of 5 g/kg could not completely ameliorate
aflatoxicity in broilers, although it met the stringent European regulation requirements for the minimum of 90% aflatoxin binding
efficiency in in vitro study.
