Favorable conditions for development, reproduction, and accumulation of large amounts of zoophilous flies in commercial poultry farms are caused by incomplete compliance with veterinary and sanitary rules for growing in cage facilities. The purpose of the study was to test a systematic insecticidal program for destroying flies’ populations using adulticide and larvicide drugs in poultry farms under battery cage management. The number of imago flies in hen houses was dynamically evaluated using flypapers, six flypapers in each hen house, situated in different levels above the floor. Flypapers were removed and the number of stuck insects was counted. The number of larvae was evaluated in dynamics by specimen testing from the floor area 10x10 cm, with weight of 3-5 g. The Quick Bayt WG 10% was applied to destroy the imago of flies. Baycidal® WP 25% was used against larvae of flies. Complex insecticide program Quick Bayt WG 10% + Baycidal® WP 25% provided the opportunity to destroy flies, with a significant difference in intensefficacy, (98.3 % for adult flies and 99.8 % for larvae). Furthermore, this program had a positive impact on economic indicators of meat production of broilers. The present study demonstrated high preventive efficacy and economical efficacy of complex program against flies under battery cage broiler management.

Lycopene is a powerful antioxidant present in tomatoes and other vegetables and fruits. Present research was carried out to evaluate lycopene and nitrogen retention and crude fiber (CF) digestibility of steaming tomatoes waste powder which was combined with oil. Tomatoes waste in this experiment were local fresh tomato rejected from tomato field around West Sumatera province, Indonesia. The experimental factors were included the type of oil (palm and coconut oils) and dosage of oils (0.25, 0.5, 0.75, 1, and 1.25 %), and each treatment was replicated three times. The results indicated there was an interaction between the type of oil and dosage of oil on lycopene retention, and CF digestibility, while the type of oil and dosage of oil affected lycopene retention significantly. The dosage of oil also influenced lycopene retention, nitrogen retention, CF digestibility significantly. The addition of coconut oil in steaming tomato waste powder increased lycopene and nitrogen retention, and CF digestibility higher than the addition of palm oil to steaming tomato waste powder in broiler chickens. The lycopene and nitrogen retention, and CF digestibility of steaming tomato waste powder added 0.5% coconut oil was the best level for lycopene and nitrogen retention, and CF digestibility in broiler chickens.

The main purpose of the present study was to find an alternative source for traditional energy to provide the energy requirements in the poultry industry. The present study was conducted in four poultry houses with different heating systems (solar and conventional) and ventilation rates located in El-Sharkia Governorate, Egypt, during June and July 2018. In this study, it was found that productivity increased by increasing the ventilation rate, where productivity reached 2.3 kg when using a solar heating system with a ventilation rate every two minutes. Productivity decreased in poultry houses with a conventional heating system and was 2 kg in ventilation rate every 2 minutes, and 1.8 kg in the ventilation rate every four minutes. The level of ammonia was also reduced with the ventilation rate every two minutes. Concentrations of ammonia ranged from 22 ppm at ventilation rate every two minutes to 28 ppm at the ventilation rate every four minutes. In addition, solar energy provided good levels of thermal requirements. It was demonstrated that solar energy as an alternative source to the conventional energy, is very efficient and can be applied on a large scale when combined with conventional electricity as a light source and within specified limits.

Poultry production is presently the most effective animal production industry and provides an excellent source of protein production worldwide. The poultry gastrointestinal microbiota includes commensal, mutualistic and pathogenic microbes. The relationship between host and gut microbiota can affect the balance of mutualism and pathogenicity. The imbalanced gut microflora caused by the incidence of disease, hygiene conditions, diet, management practices, and environmental stress affects the survival and productivity of chicken. Maintenance of the gut microbial composition is possible through the regulation of the gastrointestinal microbiota by suppressing the growth of pathogens. For many years, antibiotic growth promoters have been used to manage these problems. Nowadays, because of the emergence of antibiotic-resistant bacteria, other alternatives are being sought. Supplementation of probiotics as feed additives is considered to enhance chicken productivitity and to protect the gut from pathogen colonization and help to tolerate environmental stress. The goal of the present article was to review the poultry gastrointestinal microflora and probiotics role in the health and growth of poultry. In addition, this article focused on probiotic microorganisms and their potential characteristics.

The current study was aimed to investigate the effects of feeding Mospilan and Actara insecticides on egg production performance and meat quality of laying hens. Experimental research was conducted in the laboratory of the Department of Pharmacology and Toxicology of the National University of Life and Environmental Sciences of Ukraine in 2015. The experiments were performed on five groups each consisting of seven chickens. The age of the chickens at the beginning of the experiment was 150 days. The birds were fed the granulated compound feed. In M1 and M2 groups, Mospilan at doses of 65 mg/kg and 32.5 mg/kg of body weight were added to the feed, respectively. In A1 and A2 groups, Actara at doses of 360 mg/kg and 180 mg/kg of body weight were added to the feed, respectively. Chickens of the control group were fed without the addition of insecticides to the feed. The feeding period lasted 30 days and finally, egg production performance, meat quality, and gross pathological changes were evaluated. Egg production rate in M1 and M2 groups in comparison to the control group decreased by 78.4 and 29.7%, respectively. Egg production rate in A1 and A2 groups reduced by 89.2% and 48.7% compared to the control group, respectively. Chickens in groups of receiving insecticides had pale skin and enlarged heart, also showed spot hemorrhages in mucous membranes of the glandular stomach and intestine, color heterogeneity of the lungs, and the liver was dark cherry in color with hemorrhage. In addition, the relative weights of internal organs decreased by 23-36% in experimental groups. In the experimental groups, the pH of meat decreased at day 4 post-slaughter, and the meat broth with the addition of 5% copper sulfate solution was slightly cloudy with flakes. The meat of birds from the experimental groups was low toxic. Extracts from chicken meat of the experimental groups caused pathological changes, inhibition of movements and death of 13-16% of Tetrahymena pyriformis infusoria. This study demonstrated that the presence of Mospilan and Aktara in feed reduced the egg production rate, caused chronic poisoning, changed biochemical processes in chicken meat and increased its toxicity.
