Abstract Restrictions on access to important components of poultry rations such as corn and soybean meal are among the biggest issues in the poultry feed industry. Quinoa with a very high nutritional value can be a good alternative. The present study aimed to investigate the effect of processed quinoa seeds on performance, small intestinal morphology, and blood parameters of Ross broiler chickens. The present experiment was performed with 5 treatments, 4 replications, and 15 chickens per pen in a completely randomized design. Hydrothermal, extrusion, and expansion methods were used to process quinoa seeds. Apart from the control treatment, 15% of quinoa seeds were included in the other treatments. The studied traits were recorded. The general linear model procedure in SAS software was used to compare the means of treatments. The effect of processing methods on body weight, feed conversion ratio, total protein, uric acid, and blood cholesterol, villi height, crypt villi depth, and length to depth ratio of cryogenic villi of jejunum were significant (P<0.01). Quinoa processing improved its nutritional properties. In general, extrusion and expansion processing methods were more effective than the hydrothermal method in improving the quality of quinoa.

Micro Organisms

It is well known that alternative food additives are being researched following the prohibition of the addition of antibiotics to poultry feed as growth factors. Recently, antimicrobial peptides (AMPs) have been considered as alternatives to antibiotics. AMPs, produced by bacteria, insects, amphibians and mammals, as well as by chemical synthesis. In particular, their natural antimicrobial properties and their low tendency to create resistance in micro-organisms suggest that they might be a good alternative to antibiotics. They are not only effective against bacteria, but are also known to be effective against fungi and viruses. In studies on pigs and broiler chickens, they have been shown to be beneficial effects on growth performance, nutrient digestibility, the immune system, intestinal morphology and gut microbiota. Antimicrobial peptides are small biological molecules formed from 12-60 amino acids. AMPs have been reported to kill bacteria, in particular those showing resistance to multiple antibiotics. AMPs block the development of harmful bacteria while encouraging the growth of beneficial bacteria. For instance, it has been reported that sublancin reduces the Clostridium perfringens count while increasing the numbers of Lactobacilli. Furthermore, they have been proved to have a strong effect against Staphylococcus aureus and Pseudomonas aeruginosa. Some of the AMPs used in broiler chicken feeding are sublancin, secropin, magainin, nisin and defensin. These peptides can be used by adding them to feed or to drinking water. This review has attempted to find an answer to the question of whether AMPs added to the feed of broiler chickens can be an alternative to antibiotics by examining previous studies.

Lactobacillus Spp

The effect of dietary genistein on performance, intestinal morphology, caecal Lactobacillus spp. count, and tibia composition in broiler chickens after 21 and 37 days of feeding was investigated. A total of 360 Cobb 500 broiler chickens (21 days old) were randomly allocated to five treatments with six replicates of 12 birds each. They were fed a basal diet (C) or a basal diet supplemented with 200 (T1), 400 (T2), 600 (T3) and 800 (T4) mg genistein/kg of feed. Genistein supplementation did not affect feed intake, but improved bodyweight, weight gain and feed conversion ratio (FCR) after 21 days, while 600 mg/kg led to a significant increase in FCR after 37 days of feeding. Plasma triglyceride level decreased with dietary genistein after 21 days, while increases were found in T3 and T4 groups after prolonged supplementation. Significantly improved duodenal and jejunal villus length and width, crypt depth and villus/crypt ratio were observed after the first and the second finishing periods, respectively, while adverse effects were found in the ileum for both periods. At 42 days old, greater spleen and heart weights were measured in broilers fed diets with 800 mg/kg than in other broiler groups. The shorter genistein supplementation period (21 days) of 200 and 400 mg/kg had a positive effect on tibia wet weight, ash and calcium (Ca) content, while 37 days of the higher genistein doses administered to the T2, T3 and T4 birds significantly increased caecal lactic acid bacteria (LAB) counts. Thus, recommended doses should not exceed 400 mg/kg. Keywords: broiler performance, blood triglyceride, Lactobacillus, prolonged fattening, small intestinal morphology

Quadratic Effect

The objective was to evaluate increasing levels of dried brewers’ grains (DBG) in feed for broiler chickens from 1 to 21 days old and their effect on performance, blood parameters, intestinal morphometry, carcass characteristics and meat quality. The design was completely randomized with six treatments, which consisted of various levels of DBG inclusion, namely 0 (no inclusion), 20, 40, 60, 80, and 100 g/kg with seven replications and 17 animals per experimental unit, totalling 714 male broilers. Performance parameters, blood biochemical profile, morphology of the intestinal epithelium (duodenum), and carcass yield and composition were evaluated. Feed intake was not changed by DBG inclusion levels. Nor were weight gain and feed conversion ratio. Serum cholesterol levels were not influenced, and there were no effects on triglyceride, uric acid and creatinine levels. Enzyme aspartate aminotransferase showed a quadratic effect, as did alanine aminotransferase, with higher values at 79.5 and 63.9 g/kg DBG inclusion, respectively. No changes in carcass yield and relative organ weight were observed. The composition of the carcass in ether extract showed a quadratic effect, as fat deposition rate, with lowest values at 62.8 and 62.4 g/kg of DBG inclusion levels, respectively. Crude protein levels in carcass reduced linearly, as did fat deposition rate. The parameters of intestinal morphology and meat quality were not changed. Dried brewers’ grains can be included in broiler diet from 1 to 21 days at levels up to 100 g/kg without influencing the metabolic parameters and broiler performance.

Enzyme Supplementation

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

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.

Lipid Status

The aim of this study was to investigate the effect of dietary garlic powder addition on productive performance and blood lipid status of broiler chicken. At the beginning of experiment, three treatments of 150 one day old broiler chickens of hybrid line Hubbard per treatment, on a total of 450 chickens were formed. Every treatment was divided in four groups which represents four replicates of the experiment. Control treatment (T1) was fed with mixtures without addition of garlic powder, while experimental treatments were fed with addition of 0.5% (T2) and 1.0% (T3) of dietary garlic powder, respectively. Experiment lasted 42 days. After the completion of experimental period the highest achieved body weight of chicken was at treatment T2 (2371.1g) which was followed by treatment T3 (2336.1 g) with statistically significant differences (p<0.05) compared to control treatment. For the entire experimental period, feed conversion ratio was lowest in treatment T2 (1.8 kg/kg) and the highest in control treatment T1 (2.1 kg/kg), without statistically significant (p>0.05) differences. Addition of garlic powder led to a statistically significant (p<0.05) increase in values of EBI in compare to a control treatment T1. The highest mortality rate (5.1 %) and the lowest EBI (220.4 %) were recorded in control treatment. Addition of garlic powder in the amount of 1.0% (T3) significantly (p<0.05) decreased LDL concentrations in blood serum. The lowest concentration of total cholesterol was recorded at treatment T2 (p<0.05). The highest concentration of HDL (44.8 and 39.6 mg/dl) was recorded in treatments T3 and T2. It could be concluded that the addition of garlic has positive influence on chicken production and blood lipid status, but the further investigation of their mode of action is still necessary.
