The present study was conducted to evaluate the efficacy of the feed additive, a novel multicomponent mycotoxin detoxifying agent (MMDA) containing modified zeolite (clinoptilolite), Bacillus subtilis, B. licheniformis, Saccharomyces cerevisiae cell walls, and silymarin, as detoxifiers of 0.5 mg/kg (0.5 ppm) ochratoxin A (OTA) and 1 mg/kg (1 ppm) T-2 toxin on broiler chickens. A total of 240 1-old broiler chickens (Ross 308) were randomly distributed into five different dietary treatments: (1) control (non-contaminated diet); (2) non contaminated diet + 3 g/kg of MMDA; (3) non-contaminated diet + 0.5 mg/kg OTA + 1 mg/kg T-2 toxin; (4) non-contaminated diet + 0.5 mg/kg OTA + 1 mg/kg T-2 toxin + 1 g/kg MMDA; and (5) non-contaminated diet + 0.5 mg/kg OTA + 1 g/kg T-2 toxin + 3 g/kg MMDA. The results showed that, in the starter period, from 1 to 10 days, the presence of OTA and T-2 mycotoxins reduced the consumption of feed and the growth of the broilers, and no effects of the detoxifying product were observed in the productivity of the chickens, at any of the doses tested, compared to the contaminated control (treatment 3). However, in the growing period, the same negative effect of mycotoxins was registered, but a recovery was observed in the consumption of feed and in the weight of the broilers that consumed 3 g/kg of the MMDA mycotoxin binder, reaching similar values to those of chickens fed uncontaminated control diets. The presence of mycotoxins in feed led to a reduction in the concentration of total proteins and albumin in blood compared to controls, and the presence of the detoxifying product partially reversed this effect. The breast yield of the chickens fed with mycotoxins was lower than that of the animals fed with the control feed and was not affected by the presence of the product tested, at 1 or 3 g/kg. The weight of the different organs (liver, gizzard, kidneys, or spleen), the intestinal pH, the histology of the small intestine, and oral lesions were not affected by the experimental treatments. In summary, the productive parameters and some blood and carcass characteristics of broiler chickens were impaired by the dietary presence of OTA and T-2 toxin. The tested product included at 1 or 3 g/kg feed in contaminated diets improved performance and seems to be effective in partly counteracting the deleterious effects of the tested mycotoxins.

The experiment was conducted to determine the effects of broiler chickens dietary kaolin, bentonite and zeolite supplementations on broiler thigh meat water holding capacity (WHC), lipid oxidation (TBARS), pH, and meat color during frozen storage. A total of 448-dayold sexed broiler cockerels were randomly assigned into 28 experimental units. A cornsoybean meal basal diet with 0, 15 and 30 g/kg kaolin, bentonite and zeolite as feed additive were added to control and 6 dietary treatments. Chickens were slaughtered and the left thighs kept at −20°C and analyzed after 1 and 150 days of storage. Experimental treatments had no effect on meat WHC, pH and color. Freezing at −20°C for 150 days impaired meat quality and caused chicken rancidity; however, lipid oxidation measured by TBARS value was significantly lower in chickens received diets including 15 g/kg bentonite and kaolin comparing to control diet after 150 days of frozen storage (P<0.05). It was concluded that though adding silicate minerals did not significantly influence WHC, pH and color in experimental treatments, they had influenced lipid oxidation and decreased chicken meat rancidity during frozen storage period

The aim of this research was the visual characterization and investigating the effects of Alternaria spp. contaminated wheat grains in the starter stage of broilers nutrition on productive parameters and oxidative stress. The research was divided into two phases. Bunches of wheat in post-harvest period of year 2020 was collected from a various locality in Serbia and Albania. In the first phase, collected samples were visual characterized by Alternaria spp. presence by color measurement methods. Gained results are conferred in the range of the color properties of grain color properties of Alternaria toxins. Wheat grain samples were significantly different (p < 0.05) in terms of all measured color parameters (L*, a*, b*). Classification of field fungi in analyzed wheat grain samples showed that the significant field fungi were Rhizopus spp., followed by Alternaria spp., and Fusarium spp. In the second phase, biological tests with chickens were carried out during the broiler chickens’ dietary starter period in the first 14th days of age. At the beginning of the experiment, a total of 180-day-old Ross 308 strain broilers were equally distributed into three dietary treatments, with four replicates each. Dietary treatments in the experiments were as follows: basal diet without visual contamination of Alternaria spp. with 25% wheat (A1), a basal diet with visual contamination of Alternaria spp. with 25% wheat from Serbia (A2), basal diet with visual contamination of Alternaria spp. with 25% wheat from Albania (A3). The trial with chickens lasted for 14 days. After the first experimental week, wheat infected with Alternaria spp. in treatment A2 and A3 expressed adverse effects. The highest body weight of chickens of 140.40 g was recorded in broilers on control treatment A1 with statistically significant differences (p < 0.05) compared to treatments A2 (137.32 g) and A3 (135.35 g). At the end of the second week of test period, a statistically significant (p < 0.05) difference in body weight of broiler chickens could be noticed. The highest body weight of 352.68 g was recorded in control treatment A1, with statistically significant differences compared to other Alternaria spp. treatments. The lowest body weight of chickens was recorded in treatment A3 (335.93 g). Results of feed consumption and feed conversion ratio showed some numerical differences between treatments but without any statistically significant differences (p > 0.05). Alternaria spp. contaminated diet increased glutathione (GSH), glutathione reductase (GR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and decreased peroxidase (POD) and superoxide dismutase (SOD) serum levels, respectively. Built on the achieved results, it can be concluded that the wheat contaminated with Alternaria spp. in broilers nutrition negatively affected growth, decreased oxidative protection and interrupted chicken welfare in the first period of life.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

The progressive increase in the cost and scarcity of conventional feedstuffs, especially energy and protein sources has resulted into a continuous effort in researching into the possible utilization of the under - exploited wild legumes in poultry feed formulation. Several Researchers had reported on the utilization of Moringa oleifera leaf meal in poultry diets whereas; few reports exist on the utilization of Moringa seed. Therefore, this study wasconducted to evaluate the effect of graded dietary levels of moringa seed cake (MSC) on the performance of broiler chickens. A total of 195, one day old Arbor Acre broiler chicks were randomly assigned into five dietary treatments of moringa seed cake, each treatment having three replicates in a completely randomized design. MSC was included at levels of 0, 5,10, 15 and 20% respectively. Feed and water were given ad- libitum. Proximate composition ofMSC showed that it is high in energy, crude protein and ether extract with3304. 39 ME kcals/ kg, 32.49 % and 17.70%, respectively. Birds fed 5% MSC diet were better than the birds on the other levels of MSC diets in terms of growth and carcass characteristics. The results obtained from growth study revealed a significant declined in, final weight, weight gain, feed intake, and feed conversion ratio as the inclusion levels of MSC increased beyond 5% in thediets. The birds on control diet had the best result in terms of final weight , daily weight gain and daily feed intake of 2974g/bird, 52.4g/bird / day and 107.51g/bird/ day respectively followed by those fed diet containing 5% MSC with 2183.4g/bird, 38.24/bird /day and 95.66g/bird /day respectively. whereas, the birds fed 20% MSC had the least (P>0.05) final weight, daily weight gain and daily feed intake of 560 g/bird, 9.26g/bird /day and 33.51g/bird/day respectively. Carcass characteristics followed similar trend as the growth parameters. Hematological indices showed significant differences across the dietary treatments, however, the results were within the normal range except for the white blood cell. It can therefore be, concluded that the inclusion of MSC in broiler chicken diet should not exceed 5% for optimum growth and general performance.

Abstract The objective of this experiment was to evaluate the effects of a phytogenic feed additive (PFA-F, Digestarom® Finish, BIOMIN America Inc.) on growth performance and carcass characteristics of grow-finish pigs compared to a control, two commercial PFA products (A and B), and a ractopamine feeding program. Two hundred pigs (Choice Genetics, BW = 24.88 ± 0.53 kg) were randomly allotted to 5 dietary treatments and fed diets based on 4 dietary phases. Dietary treatments consisted of: CON, a corn-soybean meal based diet; RAC, 4.5 ppm Ractopamine HCl was added into CON for the last 21 d; PFA-A (commercial product A) was added into CON when pigs reached 90 kg of BW; PFA-B (commercial product B) was added into CON from 75 kg of BW; PFA-F was added into CON from the beginning (25 kg of BW). Body weight and feed disappearance were recorded at the end of each phase, and carcass traits were measured at the end of the trial. Data were analyzed using the Mixed procedure of SAS. No differences were observed from phase 1 to phase 3 among the treatments. At the end of phase 4, RAC had a higher (P &lt; 0.05) BW than the CON, PFA-A, or PFA-B (127.5 vs.123.1 or 121.5 kg); however, no difference between RAC and PFA-F in BW (127.5 vs.124.0 kg) was found. Pigs fed PFA-F had a higher (P &lt; 0.05) hot carcass weight than those of fed CON or PFA-B (93.0 vs. 88.8 or 88.8 kg). No differences were found in lean percentage, fat depth, and loin depth among the treatments. In conclusion, PFA-F (Digestarom Finish) supplementation resulted in similar growth performance and hot carcass weight when compared to a Ractopamine feeding program during the grow-finish period, whereas either commercial product A or B had significantly lower performance than feeding Ractopamine.

A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each in order to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield was not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, Lactobacilli count in the gut of broilers significantly (p<0.05) increased in T2 compared to that of T1. Lactobacilli count in the gut of broilers received T1, T3 and T4 did not differ significantly (p>0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of Lactobacilli.

Dietary coniferous resin acids have previously been suggested to support the intestinal integrity of broiler chickens by reducing mucosal collagen degradation. The present study examined the effects of resin acid concentrate (RAC) on broiler performance and litter quality. In trial 1, RAC was added to diets at 0, 125, 250, or 1250 g/ton, while in trials 2 and 3, RAC dosing was 0 or 175 g/ton. Bird weight, feed consumption, mortality, feed conversion ratio (FCR), European Efficiency Index (EEI), litter moisture, and footpad dermatitis (FPD) lesions were measured. In trial 1, RAC at 125 and 250 g/ton improved weight gain and EEI, while RAC at 1250 g/ton group did not differ from control. Feed consumption, FCR, FPD scores and mortality were similar in all treatments, but litter quality was improved by all doses of RAC. In trials 2 and 3, RAC increased the final weight of birds, improved FCR, EEI, and litter quality, but had no effects in other parameters. In summary, RAC at 125–250 g/ton improved bird performance and thus shows promise as a feed additive. The dryer litter in RAC treatments may suggest improved intestinal condition as a response to in-feed resin acids.

One hundred and eighty (180) unsexed twenty-one day-old growing Japanese quails (Coturnix coturnix japonica) were fed for 28 days with diets in which maize was replaced with cassava grit at 0, 25 and 50% with or without β-glucanase supplementation. The birds were randomly grouped into six treatments in three replicates of ten birds per replicate. Diet 1 was the control without cassava grit while diets 2 and 3 had 25 and 50% of their maize contents replaced with cassava grit respectively. Diets 4, 5 and 6 were the same as diets 1, 2 and 3 respectively but for the inclusion of β-glucanase at 100mg/kg. Feed and water were supplied ad libitum throughout the period of study. Feed intake (590.98g), weight gain (93.77g) and FCR (6.35) were significantly (p<0.05) affected by the dietary treatments. 6 Among the haematological parameters monitored RBC (4.46x10 /UI) and WBC 3 (26.52x10 /UI) were significantly (p<0.05) affected by dietary treatments. Thiocynate (2.57 mg/ml), AST (290.6 U.I/L) and ALT (33.6 U.I/L) were also significantly (p<0.05) influenced by the experimental diets. Replacement of 25 or 50% maize with cassava grit in diets of the Japanese quail diets did not have negative effect on haematology and serum biochemistry of the birds. There were however significant differences (p< 0.05) affected by the treatments while caeca length and the lungs weight were statistically similar across the treatments. Replacement of maize with cassava grit at 25 and 50% in Japanese quail diets had no negative effect on haematology, serum biochemistry and carcass characteristics of the birds.
