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.

Completely Randomized Design

The objective of this study was to evaluate the performance of broiler chickens in different lighting programs. Broiler chickens were fed on feeders of different colours at different breeding phases. In total, 240 Cobb500™ chicks mixed at 1 d of age were used. They were distributed in a completely randomized design. The treatments followed a 2 × 4 factorial design: two lighting programs (continuous and intermittent), and four colours of feeders (white, green, blue, and red). The birds were evaluated for weekly productive performance and the data were submitted to analysis of variance and later Tukey’s test for comparison of means. In the periods 1–7, 1–21, and 1–42 d of age, lighting programs and feeder colours affected weight gain, feed intake, and feed conversion. Intermittent red feeders influenced positively the performance of birds. It is possible to replace conventional lighting programs for intermittent lighting programs. Red feeders exert a positive influence on the performance of broiler chickens.

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.

Background: Herbal antioxidants have beneficial effects on health and performance. Meanwhile, medicinal plants and their derivations are utilized as growth and immunity promoter. Objectives: This research aimed to evaluate the effects of garlic powder and Satureja Khuzestanica essential oil (SKEO) on broiler performance, blood lipid profile, immune responses, intestinal microflora, and morphology. Methods: In total, 400 male chickens were randomly divided into five groups. Treatments included garlic powder (2 and 4%) and SKEO (400 and 500 mg/kg). Those in the control group received no intervention. On the 35th day of the experiment, the immune system of subjects was investigated, and at the end of the study, performance and blood lipid profile were analyzed. Also, the jejunal and ileal contents were separated to investigate the intestinal morphology and microflora. Results: Administration of herbal extracts was associated with improved performance, such as feed intake, BWG, and FCR (P < 0.05). Treatments could diminish the serum concentrations of lipid profile, including cholesterol, triglycerides, and LDL (P < 0.05). Meanwhile, the number of harmful intestinal bacteria was reduced by garlic (4% of diet) and SKEO (500 mg/kg) treatments (P < 0.05). Also, morphological characteristics of the intestine were improved (P < 0.05). Herbal plant supplement remarkably increased the villus length, villus length to crypt depth, and villus area (P < 0.05), but did not affect the immune responses (P > 0.05). Conclusions: This study demonstrated that dietary inclusion of herbal extracts is potentially an effective strategy for improving health and performance in broiler chickens.

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.
