Disinfection of environmental objects against coccidia oocysts in broiler chickens

The purpose of the research is developing a method for disinfection of environmental objects against coccidia oocysts in broiler chickens.Materials and methods. At the VNIIP – FSC VIEV vivarium, a bioassay test was performed to experimentally infect 60 chickens aged 14 days which were divided into six equivalent groups of 10 birds each and kept isolated in cages. Chickens from the first, second and third groups were administered orally, using a micropipette, 1 ml of an Eimeria oocyst suspension treated with 4, 5 and 6% solutions of the combined eimeriocide agent. Chickens from the fourth group were administered 1 ml of Eimeria oocyst suspension treated with 4% phenol solution (base drug). Chickens from the fifth group received 1 ml of a buffered solution and were used as a noninfected control. Chickens from the sixth group received 1 ml of suspension containing 2000 oocysts/mL and were used as an infected control. The efficacy of disinfection with eimeriocide and the basic drug was determined based on the percentage of decrease in the recovery of Eimeria oocysts after being exposed to drugs as compared to chickens of the infected control. The efficacy of 5% eimeriocide against poultry coccidia oocysts in a production test was determined empirically with the set of oocysts on control sites as compared with the basic drug on a poultry farm in the Moscow Region.Results and discussion. The intense-effectiveness of 4% eimeriocide against coccidia oocysts was 99.31%, and the 5 and 6% combined agent showed 100% efficacy. The basic drug, 4% phenol showed 74.65% intense-effectiveness. The results obtained in the production test of 5% eimeriocide at a dose of 0.5 l per 1 m2 with a 2 hour-exposure indicate its high efficacy for disinfection against coccidia oocysts in broiler chickens. The intense-effectiveness was 97.25% versus 59.03% efficacy of the base drug, phenol.

The purpose of the research is efficacy evaluation of the anticoccidial drug Solycox combined with the feed additive Chiktonik against avian eimeriosis.Materials and methods. The experiments were carried out on the Makhachkalinskaya poultry farm, which was contaminated with eimeriosis, on healthy 1 day old Ross-308 broilers. Two groups were formed from the selected chickens, test and control, 50 birds each. From the first day of life, broiler chickens from the test group were administered Solycox at a dose of 2 ml per 1 liter of drinking water combined with the feed additive Chiktonik at the rate of 1 ml per 1 liter of drinking water. The control chickens were not prescribed any anticoccidial drug or feed additive.Results and discussion. We established high efficacy of Solycox combined with Chiktonik against eimeriosis of broiler chickens (96%). Solycox combined with Chiktonik contributes to the poultry viability and resistance to the disease, and has a positive effect on productivity. The results of the studies allow us to recommend Solycox and Chiktonik to prevent and treat eimeriosis of broiler chickens.

Impact of Storage Period on Fertility and Mortality in Chabro Breeds of Poultry

An investigation was conducted to study the effect of storage period on fertility and hatchability in large, medium and small sized eggs of Chabro breed. The study was conducted at poultry farm of SKN College of Agriculture, Jobner. For the present study, a total of 297 eggs were collected for this study. These eggs were grouped into three egg size categories i.e. Small (38-44 g), medium (45-52 g) and large (53-59 g). To study the impact of incubation period, eggs were stored at 21 ̊C temperature for three different time periods (fresh, 3 day and 6 day). It was observed that egg fertility was increased on 3rd day and decreased on 6th day as compared to 0 day. For small egg class, egg fertility was 95.55, 96.02 and 92.13% respectively, on 0, 3 and 6 day of storage. Similarly, for medium-sized egg class, fertility was 95.17, 95.64 and 90.28% and for large sized egg class, it was 91.11, 92.15 and 87.41% respectively, on 0, 3 and 6 day of storage. Embryonic mortality increased with increase in storage duration. For small egg class, egg mortality was 20.95, 17.56 and 24.87% respectively, on 0, 3 and 6 day of storage. Similarly, for medium-sized eggs class, mortality was 10.15, 8.45 and 12.63% and for large sized egg class, it was 29.30, 20.14 and 33.41% respectively, on 0, 3 and 6 day of storage. The egg fertility and mortality are affected by the storage period. For best hatchability, egg storage should not exceed 3 days.

Environmental Perception Q-Learning to Prolong the Lifetime of Poultry Farm Monitoring Networks

The reduction of the effects of heat-stress phenomena on poultry health and energy conservation of poultry farm monitoring networks are highly related problems. To address these problems, we propose environmental perception Q-learning (EPQL) to prolong the lifetime of poultry farm monitoring networks. EPQL consists of an environmental-perception module and Q-learning. According to the temperature and humidity model of heat stress, an environmental-perception module determines the transmission rate, while Q-learning adjusts the transmission rate according to the success rate of packet transmission and the remaining energy. In real-world tests, our poultry farm monitoring networks used only about 8% of energy in a month. The real-time information of these monitoring networks was available on smartphones. In laboratory tests, compared with CSMA/CA (23.67 days), S-MAC (109.37 days), and T-MAC (252.79 days) under real systems with 2000 mAh battery, the battery-life performance of EPQL (436.48 days) was better. Moreover, EPQL reduces the packet loss rate by about 60% while simultaneously decreasing the average delay by about 20%. Generally, based on the framework of EPQL, the implemented temperature and humidity model of heat stress for poultry could be replaced by other models to extend its applicability range.

Meat yield characteristics of different upgraded dwarf chicken under intensive management condition

The study was conducted with attempts to determine the effects of autosomal dwarf (adw) gene introgression from Indigenous dwarf chicken (IDC) to White Leghorn (WLH) and Fayoumi (Fay) on growth and meat yield characteristics. Experiment was carried out at the Poultry Farm of Bangladesh Agricultural University (BAU), Mymensingh for a period of 28 months from March 2013 to June 2015 under intensive management condition. In this study, the di-allele crossing between WLH, Fay and IDC produced 4 up-graded chickens viz. IDC♂ × WLH♀, WLH♂ × IDC♀, IDC♂ × Fay♀ and Fay♂ × IDC♀. The up-graded F1 generations were mated intersex to access their productivity. The up-graded F1 generations were mated intersex to access their productivity. Pre-slaughter live weight of birds significantly (P<0.001) varied by genotype, sex and genotype × sex interaction. Percentage of thigh meat, drumstick meat, dark and total meat weights was significantly influenced by genotype. Although meat yield parameters of male birds in relation to live weight were found higher than their female birds, some parameters like breast meat, liver, giblet and total meat yield were found higher in female birds than that of male birds of all genotypes. However, meat yield parameters like percentage of thigh, drumstick and total meat yield were the highest in IDC♂ × Fay♀ and Fay♂ × IDC♀ and the lowest in IDC♂ × WLH♀. From the above findings, Fayoumi mediated dwarf genotypes showed better meat yield characteristics than Leghorn mediated dwarf genotypes.

Methodological recommendations for rationing the number of injuries observed during delivery were developed. The study of losses of live birds during delivery to the processing plant from the density of stocking in shipping boxes was carried out; the economic and mathematical model for optimizing the landing of live birds in shipping boxes was proposed. The calculation of the economic impact of the implementation of the results of the study is given.

Effect of Storage Time On the Hatchability of Eggs of Two-Line Dual-Purpose Combination for Production of Male Chickens for Meat

The aim of the study was to assess the effect of the storage time on the hatching traits of eggs obtained from a two-line dual-purpose combination for production of male chickens that will be utilized for meat. The trial was carried out in the experimental poultry farm of the Institute of Animal Science-Kostinbrod, with a total of 150 Lohmann Brown Classic layers, at the age of 54 weeks. Hatching eggs were gathered for three weeks and were stored for 5, 10 and 15 days at 15-18°C ambient temperature prior incubation. The storage time had no effect on the fertility of the set eggs, however, it adversely affected the hatchability. Prolonged storage led to significant decline in the total hatchability (P=0.0027) and the hatchability of the fertile eggs (P<0.0001) which was lowest after 15 days of storage prior incubation. The viability of the chickens was influenced by the storage of the eggs prior incubation (P<0.0001), and decreased considerably when the chicks were hatched from eggs stored for 15 days.

Automatic Temperature Control System on Smart Poultry Farm Using PID Method

Chicken farmers in Indonesia are facing a problem as a result of the country's harsh weather conditions. Poultry species are very susceptible to temperature and humidity fluctuations. As a result, an intelligent poultry farm is necessary to intelligently adjust the temperature in the chicken coop. A smart poultry farm is a concept in which farmers may automatically manage the temperature in the chicken coop, thereby improving the livestock's quality of life. The purpose of this research is to develop a chicken coop prototype that focuses on temperature control systems on smart poultry farms via the PID control approach. The PID control method is expected to allow the temperature control system to adapt to the temperature within the cage, thereby assisting chicken farmers in their tasks. The sensor utilized is a DHT22 sensor with a calibration accuracy of 96.88 percent. The PID response was found to be satisfactory for the system with Kp = 10, Ki = 0, and KD = 0.1, and the time necessary for the system to reach the specified temperature was 121 seconds with a 1.03 % inaccuracy.
