التحليل الإقتصادي لتأثير مرض إلتهاب الجلد العقدي للأبقار علي الثروة الحيوانية بمحافظة أسيوط

Abstract EN

The breeding of cows is one of the most important elements of production in Egypt in general and the province of Assiut in particular.

As it represents an important part of the economic wealth as the attention to these animals in terms of veterinary care and immunization at the appropriate times and care and raising education and productivity are considered of the important aspects to achieve economic objectives .

The problem of research is in the exposure of animal production in the recent period to many problems due to the spread of serious epidemic diseases such as Foot and mouth disease and Nodal dermatitis in the cows which led to the increase in mortality in cattle and the shortage in the number of animals.

especially cows and the reluctance of many farmers to breed them.

and disposal of animals.

whether infected or healthy.

cheap prices due to the fear of the spread of the disease and suffer a lot of loss on the grounds that all the cows owned are their capital from And the amount of loss borne by the state for vaccination.

compensation and others.

The study aims to study the number of cows in Assiut Governorate and their relative importance of the total farm animals.

Study of the relationship between the degree of infection of Nodal Dermatitis of cows with the variables of breeders.

animal and climate in Assiut governorate.

To determine the effect of the disease on cattle in the study area.

to estimate the economic value of healthy and infected cattle.

to estimate the cost of treatment and the economic loss resulting from it in Assiut Governorate.

The study also aims to measure the potential effect of Nodal Dermatitis on livestock.

especially on cattle in Assiut Governorate .

And finally the study of the production problems facing the cows breeders in Assiut Governorate.

The study was based on two main sources.

the secondary data and.

the second.

field data through questionnaire forms.

which were specially designed through the personal interview of cattle breeders who have contracted Nodal Dermatitis of cattle in Assiut Governorate.

A 96 sample was taken in Assiut and Manfalut provinces.

Were divided into three categories according to age and gender: male and female cows less than one year.

male and female cows from one to two years.

and the third category was the largest cattle of three years.

The study has reached many results including the following: 1- The total number of livestock production in the governorate is about 702 thousand heads.

including 188 thousand heads of cows.

representing about 26.81% of the total number of animal heads in the province.

The province of Deirout.

the largest number of cows.

representing about 29.69% of the total number of heads of animals in the province.

while the lowest number of cows was in the province of Sahel Salim.

which represents about 29.54% of the total number of heads of animals in the province.

2- The total number of cattle animals in the sample farms was about 592 heads distributed over different ages and species.

Of them.

about 218 heads of the total number of animals infected of the sample farms were also distributed over different ages and species.

The cows were the most affected in the third category.

where female cows were the lowest in the first category.

3- It is also clear that the total number of animals in the sample is 22% of the total infected cows and 8.1% of the total cattle in the sample.

and the most vulnerable age in the second category.

and the lowest cows in the third category.

4- As shown by the study that the severity of the disease according to the classification of veterinarians and educators divided into three cases of light.

medium and severe representing about 12.5%.

13.9%.

10.5% of the total number of cattle in the sample.

respectively.

5- The study also showed a significant relationship between the severity of the injury and the level of education and immunization or vaccination of the animal and climate conditions.

while not significant with the experience of breeders.

6- The study showed that by estimating the economic indicators of cows infected with Nodal Dermatitis of cows.

the cost of treatment and the decrease in the value of animal feed and weight and the price of the animal compared to healthy animals of all species and age groups in the sample of the study.

the healthy cows of the third category.

the economic indicators represented in both net revenue .

The return to cost ratio.

the return on the investment.

and the profit margin ratio is higher for the infected cows.

while the opposite occurs for the operating ratio indicator.

7- The results of the analysis of the Probit model for the first category show that the affected animal is likely to lose 95.73%.

98.91% and 53.89%.

respectively.

while the probability of increasing the cost of treatment and period of illness is 99.48% and 83.06%.

respectively.

While it is clear from the Logit that the animal has a weighting and feeding value decreases by 92.5% and 98.1%.

respectively.

The variables of treatment costs and period of the illness lead to an increase of 99.09% and 70.28%.

respectively.

8- The analysis of the Probit model for the second category showed that the animal was less likely to lose 99.41% and 76.99%.

respectively.

with a 99.61% increase in the cost of treatment.

The Logit showed that the infected animal had a feeding value of 98.94 %.

76.09%.

while the variable treatment costs are likely to lead to an increase of 99.99%.

9- The analysis of the Probit model for the third category indicates that the animal has the potential to reduce both the value of the nutrition and milk production by 99.77%.

98.62% respectively.

and the possibility of increasing the cost of treatment by 99.77%.

while the estimate of the Logit model shows that the variable of treatment cost.

the most important and influential in animals infected with the disease the possibility of the cost of treatment increased by 99.45%.

10- The Probit model estimates that the animal has the potential to decrease the feeding value by 99.43%.

while the probability of increasing the cost of treatment.

duration of disease and animal type by 99.68%.

92.84%.

61.94%.

respectively.

while Logit model shows that the animal has the potential for feeding value decreases by 98.95%.

while the cost of treatment variables and the period of the disease and the type of animal increase by 99.37%.

87.80%.

36.72%.

respectively.

11- The study of the problems facing breeders of cows infected with Nodal Dermatitis in the sample that the three problems are: the first problem because of the spread of Foot and mouth disease in recent times.

which led to the interest of breeders to vaccinate their animals against that disease and ignore the immunizations against other diseases and the second problem as a result of exposure to animals For many diseases.

especially cows.

led to that the breeders get rid of them fearing from the disease or they do not breed new animals.

The third problem is that the government agencies do not compensate the breeders financially for the dead animals unless the animals were insured.

Although there were no significant differences between them.

The problems of the unequipped veterinary units and absence of technical devices to cope with the disease.

Awarness agencies don’t do their rule to aware breeders about the disease comes in the last place where there are no significant differences between them.

In light of the above results of the study recommends the following: 1- Immunization in terms of the effectiveness of the vaccine and the methods of transfer and the appropriate time as the methods of prevention recommend vaccination of the animal from Jan.15th to Feb.

15th of each year and the use of one syringe for each animal.

2- Fight the intermediary host represented in mosquitoes and flies to reduce the spread of the disease through the use of protection of the sheds by wire or spraying animals with insecticides or disinfecting the barns solution 2% sodium hydroxide or formalin solution.

3- Good animal care.

isolation of the infected animal and use of medicines to treat symptoms such as heat reducers.

anti-biotic.

anti-inflammatory and anti-histamine to avoid annual infection of the animal.

4- the sanitary disposal of carcasses of dead animals and of infected skin by burning or burying to reduce the spread of infection
