“…AFB 1 has been shown to have a strong hepatotoxic effect, but it can be minimized, for example, by supplementing the food with curcumin [94]. Control of the production of mycotoxins and the growth of molds responsible for their formation should be a priority issue for food producers, both for humans and animals [95]. A study by Singh and Chuturgoon [96], the purpose of which was to compare the microbiological quality of supermarket pet foods with premium foods, showed that regardless of the manufacturer, all food samples were contaminated with fungi (mainly Aspergillus flavus, Aspergillus fumigatus and Aspergillus parasiticus), as well as their secondary metabolites (most often AFs and FBs).…”

Mycotoxins can be found in many foods consumed by humans and animals. These substances are secondary metabolites of some fungi species and are resistant to technological processes (cooking, frying, baking, distillation, fermentation). They most often contaminate products of animal (beef, pork, poultry, lamb, fish, game meat, milk) and plant origin (cereals, processed cereals, vegetables, nuts). It is estimated that about 25% of the world’s harvest may be contaminated with mycotoxins. These substances damage crops and may cause mycotoxicosis. Many mycotoxins can be present in food, together with mold fungi, increasing the exposure of humans and animals to them. In this review we characterized the health risks caused by mycotoxins found in food, pet food and feed. The most important groups of mycotoxins are presented in terms of their toxicity and occurrence.

“…In this regard, there are new modern reproduction techniques, such as embryo in vitro production and transfer to the recipient mother (Manik et al, 2003;Huang and Rosenwarks, 2012). These new techniques contribute to the intensification of the genetic improvement of the herd (Chukwuka et al, 2010) and the usefulness of slaughtered pregnant cows' oocytes.…”

A cow can give birth to an average of 6-7 calves in her entire reproductive period. The remaining oocytes could be used for the in vitro production of embryos. The present study was conducted to evaluate the effects of ovarian and non-ovarian factors on the follicular population and oocyte maturation of three Chadian cattle breeds (Arab, Kouri, and Toupouri). For this purpose, the ovaries of 166 cycled cows were collected at the Farcha slaughterhouse of Chad and placed individually in labeled conical tubes containing 0.9% NaCl and 0.5 mg/ml penicillin-streptomycin. After clearing the ovaries of tissue debris, they were weighed, and the follicles were counted. The diameter of each follicle was measured and classified into three categories. A total of 2734 oocytes were collected in 28 days with a minimum of 97 per day by the slicing method using a 10X stereoscope. They were then classified into four groups according to the structure of their cumulus oophorus. Immature oocytes (class 1 and 2 [1455]) were placed in different culture media consisting of Minimum Essential Medium (MEM) alone, MEM with 10% follicular fluid, and MEM with 50% follicular fluid for oocyte maturation. The results indicated that the mean follicular population and mean oocyte yield were 24.71 ± 0.88 and 11.65 ± 0.94, respectively. The mean oocyte index and the number of cultivable oocytes for in vitro embryo production (class 1 and 2) were 1.03 ± 0.23 and 1.65 ± 0.94, respectively. The number of follicles observed in the age group of 6-9 years was higher than in other age groups. Oocyte yield was significantly higher in cows with a body condition score of 4-5 compared to average and lean cows. Among the different culture media used for oocyte maturation, the medium consisting of MEM plus 10% follicular fluid recorded a higher maturation rate than the other culture media. Cows aged 6-9 years had a higher maturation rate than other age groups. In conclusion, the good follicle (follicle that produced oocyte) and appropriate oocyte performance were observed in cows with body condition score 3-5 and an age range of 6-9 years.

“…Pelleted feed is less susceptible to spoiling, moisture and odour adsorption, decomposition and transportation losses. Heat generated during pelleting operation, reduces total microbial count (Chukwuka et al, 2010;Lević and Sredanović, 2010;Đorđević and Dinić, 2007;Sretenović et al, 1995). And finally, pelleting process induces degradation of thermolabile antinutrients and undesirable feed mixtures ingredients (trypsin inhibitor, lectin, urease, peroxidase, lipoxygenase, myrosinase, glucosinolate, gossypol and others).…”

The study was conducted to determine effect of pelleting agents on physical and chemical characteristics as well as microbiological and mycotoxicological safety of pelleted feed mixtures for laying hens. Four feed mixtures were analyzed: Control (K)-without supplemented pelleting agent, and three experimental ones (A, B and C) with supplemented pelleting agent. Lignocellulose concentrate-based agent was added in feed mixture A-"Arbocel" (2%), and bentonite-based agent in feed mixture B "Bentopel" (2%), while both agents were added in feed mixture C in the concentration of 1%. The pellets of highest hardness (6 Khal J/kg) were found in feed mixture B. The pellets of rather good hardness (5.5 Khal J/kg) were found in feed mixture A, while the pellets in feed mixture C (3.5 Khal J/kg) were of the lowest hardness. Total number of bacteria was the highest in diet K amounting to 39000/g sample, and significantly lower in the experimental feeds mixtures ranging from 2,100 (C) to 5,000 (B). Pathogenic bacteria were not detected in the analyzed feeds mixtures. The highest number of yeast species (8) was found in feed mixture K, and in experimental feeds mixtures this number was significantly lower. In feed mixture A one yeast species was found, in feed mixture B three and in feed mixture C 6, respectively. The predominant were the representatives of the Aspergillus species, a typical mycobiota developed in the animal feed warehouses. Presence of mycotoxins (aflatoxin B1, ochratoxin A, zearalenone, deoxynivalenol, diacetoxyscirpenol and T-2 toxin) was not detected in analyzed feeds mixture.
