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.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.

An experiment was conducted for a period of 56 days with 36 healthy New Zealand White (NZW) rabbits aged about one months having weight from 370 to 390g to evaluate the effects of dietary citric acid on growth performance, feed consumption and digestibility of nutrients as well as immune status. The experiment was designed with 6 dietary treatments having 6 rabbits per treatment. Rabbits of control treatment (T1) were given the diet without citric acid (CA) but the dietary treatments T2, T3, T4, T5 and T6 contained 0.5, 1.0, 1.5, 2.0 and 2.5% CA respectively. Green grass was supplied on ad libitum basis. The total body weight gain was Addition of CA at the level of 2% enhanced body weight significantly (P<0.05). (P<0.05)(P<0.05) T 734, 776, 812, 862, 911 and 740g for the rabbits fed 0, 0.5, 1.0, 1.5, 2.0 and 2.5% CA containing diets respectively. Total DM intake also increased with increasing the percentage of CA up to 2% level . Incase of feed conversion ratio, there was no significant difference in addition to different levels of CA. Supplementation of CA improved dry matter, crude protein and ether extract digestibility but incase of crude fiber and nitrogen free extract, there was no significant difference. Non significant difference was also found incase of acidity of feed and feces. The highest lymphocyte (73%) was counted in dietary treatment T6 having 2.5% CA, which was 17% higher than the control diet. From the result of this experiment, it may be concluded that the addition of CA up to 2% level in diet improves performance, digestibility of nutrients and immune status of growing rabbit.

The aim of this study was to evaluate the effect of the baical skullcap root (<I>Scutellaria baicalensis radix</I>) on the performance, chemical composition of the muscles and sensory characteristics of the meat of broiler chickens. 120 one-day old Hubbard Hi-Y broiler hybrids were assigned to four groups of 30 each and fed either a basal diet (control) or a basal diet supplemented with 0.5%, 1.0% or 1.5% ground root of skullcap. The body weight, weight gain, feed consumption and feed : gain ratio were calculated after 42 days. The addition of the ground baical skullcap root to the fodder had no effect on the quality or chemical composition of the breast and leg muscles of the broiler chickens. However, it positively influenced some of the performance characteristics of the chickens.

Aflatoxicosis is a cause of economic losses in broiler production. In this study, the effect of one commercial nanocompound, Nanocid (Nano Nasb Pars Co., Iran) was evaluated in reduction of aflatoxin effects on the growth and performance indices in broiler chickens suffering from experimental aflatoxicosis. For this, a total of 300 one-day-old broiler chicks (Ross strain) were randomly divided into 4 groups with 3 replicates of 15 chicks in each separated pen during the 28-day experiment. Treatment groups including group A: chickens fed basal diet, group B: chickens fed 3 ppm productive aflatoxin in basal diet, group C: chickens fed basal diet plus 2500 ppm Nanocid, and group D: chickens fed 3 ppm productive aflatoxin and 2500 ppm Nanocid, in basal diet. Data on body weight, body weight gain (BWG), feed intake, and feed conversion ratio (FCR) were recorded at weekly intervals. Also cumulative data were assessed. Results showed, although supplement of Nanocid to conventional diet had no effect on performance but addition of Nanocid to diet containing 3 ppm aflatoxin increased significantly the cumulative BWG, cumulative feed consumption and decreased FCR in the last 2 weeks of experimental period. The improvement in these performance indices by supplement of Nanocid to diet containing aflatoxin showed the ability of Nanocid to diminish the inhibitory effects of aflatoxin.

Dietary Treatments

An experiment was carried out to investigate the performances with 1080 male Cobb-500 broiler chicks using different levels of a microbial phytase in plantbased diet. Six dietary treatments were formulated as follows; the first 3 diets were balanced with Ca and Av. P according to the recommendation of Cobb-500 served as basal diet without phytase enzyme (T1), basal diet with 100g phytase ton-1 feed (T2) and basal diet with 200g phytase ton-1 feed (T3), while the last 3 diets were deficient in Ca and Av. P and containing no phytase enzyme (T4), diet with 100g phytase/ton feed (T5) and diet with 200g phytase ton-1 feed (T6). All 6 treatments were replicated 6 times. Body weight, feed consumption and mortality of broilers were recorded weekly. The highest body weight was found in T3 with 200g phytase ton-1 feed with recommended Ca and Av. P level in the diet, followed by T6 with 200g phytase/ton feed with deficient in Ca and Av. P level in the diet (P<0.05). The lowest weight was found in T1 without phytase with recommended Ca and Av. P level in the diet. The feed consumption, feed conversion ratio and mortality of the birds during 35 days of experimental period did not differ significantly (P<0.05). The meat yield characteristics at 35 days of age were non-significant among different treatments (P>0.05). Significantly lower value of total ash (%), Ca (%) and total P (%) of tibia was found in control group (T1) and T4. The results of this experiment revealed that phytase supplementation at 200g ton-1 of feed improved broiler performances at either recommended or deficient level of Ca and Av. P. SAARC J.

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

The aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

Ross 308 broiler chicks (n = 240) aged 1 day were assigned to five groups for eight replicates (six chicks for each) (3♂ and 3♀). Basal dietary groups were supplemented by 2000, 4000, and 6000 mg/kg cinnamon (CN) for 21 days. Basal diet alone was used as a negative control, and basal antibiotic diet (Colimox) was used as a positive control. At 10, 14, and 21 days of age, chicks that received 2000 mg CN and Colimox had a higher body weight, resulting in an increase in body weight gain. CN also resulted in the maximum improvement in the feed conversion ratio and feed efficiency over 1–21 days at the level of 2000 mg/kg. At days 10, the maximum relative breast weight was 2000 mg/kg of CN. Mean serum albumin concentrations, duodenal villus height, and goblet cell density increased (p < 0.05) by 2000 mg/kg of CN, and mean serum globulin and total protein concentrations and crypt depth increased (p < 0.05) by 6000 mg/kg of CN compared with control. Increased cecal Escherichia coli number was CN dose-dependent. In conclusion, dietary inclusion of 2000 mg/kg CN can be applied as an alternative to in-feed antibiotics for broiler starter diet.

An investigation was undertaken on 180 day-old Hy-line layer chicks to assess the effect of herbal products on feed consumption, egg production and profitability. The experimental chicks were randomly divided in three groups with three replicates in each and were housed in identical management and environmental conditions. Dietary treatments were prepared by addition of herbal liver stimulants such as Livoliv 250 @500 g/ton (D2) and Superliv @500g/ton (D3) in the basal diet (D1). Feed intake, egg production and mortality were recorded throughout the observation period of 50 weeks. Feed per unit of egg production, hen day percentage, additional income of supplemented diet over the basal diet were calculated. Average daily intake (g) of the diets per bird were observed as 59.19±1.05 g, 58.31±0.337 g and 57.67±0.163 g up to 20 weeks and 108.94±0.06 g, 109.01±0.05 g and 108.26±0.41 g during the laying period fed with D3, D1 and D2 diets respectively. Similarly, higher hen day egg % (76.9%) was recorded in the birds fed with Superliv supplemented diet (D3), followed by Livoliv supplemented diet (D2) (73.4%) and Basal diet (D1) (72.1%) with feed intake per unit egg production of 179.3 g, 178.1 g and 193.0 g, respectively. Total egg production was found higher with D3 (161.49 egg), followed by D2 (154.15 egg) and basal diet (151.45 egg) with layer house cumulative mortality only in D3 (3.75%). Additional profits of Rs. 35.18 and Rs. 12.86 in terms of egg selling over feed cost per layer were calculated for the bird fed with Superliv supplemented diet (D3) and Liveloliv supplemented diet (D2) than that of the basal diet.
