Abstract
Fungus development in field crops or in storehouses could lead to nutritional and even physical loss, as well as to mycotoxins production, which could be extremely harmful for humans and animals. Therefore, the economic impact on animals performances could be huge and controlling mould development is in fact a key factor in preventing feedstuffs contamination with fungus and mycotoxins. There have been used several methods to prevent or treat mycotoxicosis in animals, but the usage of certain special feed additives, known as mycotoxins adsorbents of detoxifying agents is the most common one. This paper presents a part of the trial that aimed to estimate the productive and economic effects of supplementary feeding chickens broilers with the Mycofix MTV commercial product, from Biomin, at dietary inclusion rates of 1 and 3 . The biological material was represented by 111678 ROSS-308 chicken broilers, reared industrially, in deep litter system, till slaughter at 40 days old. Certain performance parameters have been investigated throughout the entire experimental period: - body weight dynamics, average daily weight gain, feed conversion ratio, mortality, as well as the economic efficacy of detoxificant additive used in broilers feeding, through the calculation of European Broiler Index (EBI) and European Production Efficacy Factor (EPEF). In all production parameters, inclusion of detoxifying feed additive generated better results (+10.8% live weight at slaughter; 6.24% less for feed conversion, hence savings of important feed quantities and moneys; 40.15% decreased casualties). Although the dietary inclusion of Mycofix MTV in chicken broilers feeding imposed supplementary expenses, it also generated better incomes and revenues, which were 1.42 33.75% higher in experimental groups L1exp. and L2exp., compared to control group-Lc.
