Allicin, diallyl thiosulfinate, has a strong antibacterial activity against a wide range of gram-negative and gram-positive bacteria. The purpose of this study was to determine the possible use of allicin as a formaldehyde alternative on broiler breeder hatching eggs. The lowest microbial counts on the eggs were obtained from formaldehyde followed by allicin. Microbial counts slightly decreased with the increasing allicin concentrations. Compared to the positive control formaldehyde, allicin treatment lowered the early and late embryonic mortality, and feed conversion ratio, but increased the discarded chick rate, pipping rate and hatchability of the fertile eggs. Allicin concentrations had no significant effect either on hatching or chick growth and development after hatching. These results imply that allicin had a potential as a hatching egg disinfectant since allicin had no detrimental effect on the developing embryo.
Review of gaseous methods of killing poultry on-farm for disease control purposes
Veterinary Record, 2006
Poultry may need to be culled in the event of an outbreak of disease. Gassing has advantages over mechanical and electrical methods or overdoses of anaesthetics because large numbers can be killed simultaneously and little or no handling of the birds is required. However, gaseous killing methods may have welfare implications for the birds, which may find various gases more or less aversive, may undergo respiratory distress and/or experience convulsions, and may remain conscious for a considerable time before they die. In addition, the gases used may present health and safety risks to human operators, and be difficult to supply and deliver.
Comparative study of different surface decontaminants on chicken quality
British Poultry Science, 2004
1. A comparative study on the effect of different surface decontaminants: hot water at 70 C for one minute; 2% lactic acid for 30 s; 1200 p.p.m. acidified sodium chlorite (ASC) solution for 5 s and 50 p.p.m. chlorine solution for 5 min in the form of dips and sprays on the surface of dressed broilers for 0, 24 and 48 h of storage was conducted. 2. The variables studied were, total plate count (TPC), presumptive coliform count (PCC), pH and extract release volume (ERV). All treatments reduced TPC and PCC. 3. Lactic acid dip and hot water dip were the most effective for reducing TPC (1. 36 and 1. 28 log/cm 2 , respectively) with no significant difference between them. 4. ASC and hot water in dip could diminish PCC (1. 37 and 1. 34 log/cm 2 , respectively) and did not vary significantly. 5. No treatment affected muscle pH, water holding capacity (WHC), ERV, appearance, smell, tenderness and overall acceptability of treated broilers significantly. 6. Hot water treatment is the cheapest, most convenient and simplest decontamination technique for hygienic and wholesome poultry production.
The present study examined the effectiveness of Oregano (Origanum vulgareL) and Ginger (Zingiber officinale) oils versus formaldehyde fumigation (FF) to disinfect White Leghorn and Matrouh hatching eggshell surface and maintain hatching results and chick performance after hatch. Hatchability was not affected by breed of birds, however, the chick quality measured as live body weight, feed conversion ratio and viability percentage of Matrouh chicks were significantly better as compared to White Leghorn chicks at 4 or 8 weeks of age. Significant differences between Origanum vulgare L or Ginger oils and formaldehyde fumigation in the hatchability of eggs were observed. Embryo mortality was lower in both of Origanum vulgare L and Ginger oils groups and their combination group compared to control and formaldehyde fumigation groups. The best chick weight at hatch time was observed in the Ginger oil group. Performance of chicks after hatch showed that the best results for live body weight a...
EFFECTS OF SOME INSECTICIDES ON GROWTH AND CLINICO-PATHOLOGICAL PARAMETERS OF CHICKENS
Agriculture University Faisalabad , 2023
The poultry sector is an important and lively section of agriculture in Pakistan with a substantial contribution to the national GDP (1.3%). Pakistan began producing commercial poultry in the 1960's and provide a large percentage of dietary proteins to the Pakistan population over since. The purpose of the current study is to investigate the effects of insecticides (Lufenuron, Betacypermethrin, Deltamethrin and Buprofezin) on pathological parameters (liver, kidney and reproductive organs) of chickens. These chicks will be divided into equal groupings of four. A, B, C, and D are the groups. Group A will be kept as controlled, Group B will be subdivided into three equal groups (B1, B2 and B3) and orally treated with lethal, sub-lethal and super lethal.

Cotton (Gossypium hirsutum L.) is the world’s leading fiber crop for textile industry in many countries. Pakistan ranks 4 in cotton production worldwide. Cotton is notorious for being susceptible to many diseases. Bt cotton is mainly affected by sucking pests after a decrease in the intensity of pesticides. The following study has been planned to check the effect of different doses of pesticides. Three neonicotinoid insecticides (nitenpyram, imidacloprid, and acetamiprid) and a same number of conventional insecticides (profenophos, λ-cyhalothrin and bifenthrin) are used to be checked. Their effect is checked on sucking insect pests in the cotton field. RCBD (Randomized Complete Block Design) is used to arrange the seven treatments containing six insecticides and one control treatment with three replications each. The data of three sucking insect pests, red cotton bug, thrips, and the dusky cotton bug was recorded after spraying at the interval of 24, 72 hours and 7 days from each pl...
Effective Fumigation to Control Stored Grain Pests (Project Report)
Now-a-days the gaseous poisons are being commonly used to kill stored grain pests. These gaseous poisons are known as fumigant. Methyl Bromide, Phosphine and Calcium Cyanide are common fumigant. Methyl Bromide is now being expected to be short-live because of its harmful effects on the atmosphere. Phosphine is now being used successfully throughout the world. However insects’ resistance is being increased against this fumigant. Calcium Cyanide is highly poisonous for respiration, that’s why its use is now being limited. Author Note: This research project was assigned by the management of Matco Rice Processing (Pvt.) Ltd. to the Quality Control Department and completed during July 1998-January 2000.

The study was conducted at 6 tehsils (Newai, Tonk, Uniara, Todarai singh, Deoli and Malpura) of Tonk district of Rajasthan. One thousand and two hundred chicks of six weeks age were purchased from Maharana Pratap University, Udaipur, Rajasthan. Two groups of ten farmers each were sekected from each tehsil. 10 chicks were provided to each farmer which was broiler and layer mixed. The average increased weight of broiler was 3.66±19.34 kg under Akodia village group and 3.94±19.34 kg was under Talibpura village group. Akodia village group was slowly gaining weight compare than Talibpura village group because they were providing vermin waste which contained more amounts of proteins. The findings of Harnoda village group in I, II, II, IV, V and VI month was found to be 480±22g, 480±14g, 640±09g, 710±22g, 720±20g and 730±21g fed crop waste to the poultry chicks and other essential contents of diet were similar with other groups. In case of meat it was slowly growing compare than Fuleta village group because Fuleta village group was providing Fish waste which contained more amounts of vitamins and minerals. Harnoda village group reported the number of egg was 06±01, 07±02, 09±01, 10±02, 09±01 and 09±02 respectively in six months with an average of 8.33±02. The performance of Harnoda village group was better than Akodia and Fuleta village group but poor in comparison with Talibpura, Panwar and Barbas village group because of difference in feeding, locally available sources of feed and water quality. Talibpura village group reported that the number of egg was 08±02, 10±02, 11±01, 11±02, 10±02, 11±02 and 11±03 respectively in six months with an average of 10±02. It was best performance of this study due to improved feeding, water quality and managmental factors. Environmental factors may affect the production of broiler and layers.
