Ранее я делал серию постов про битовые операторы.
Вот вам ещё один наглядный пример как это используется в Python в модуле re.
Чтобы указать флаг для компилятора нам надо указать его после передаваемой строки. Например, добавляем флаг для игнорирования переноса строки.
pattern = re.compile(r"(\w+)+")
words = pattern.search(text, re.DOTALL)
А как указать несколько флагов? Ведь явно будут ситуации когда нам потребуется больше одного. Кто читал посты по битовые операторы уже понял как.
pattern.search(text, re.DOTALL | re.VERBOSE)
А теперь смотрим исходники, что находится в этих атрибутах?
Не удивительно, степени двойки. Почему? Потому что каждое следующее значение это сдвиг единицы влево.
>>> for n in [1, 2, 4, 8, 16, 32, 64, 128, 256]:
>>>
print(bin(n))
0b1
0b10
0b100
0b1000
0b10000
0b100000
0b1000000
0b10000000
0b100000000
Чтобы было понятней, давайте напишем тоже самое но иначе, добавим ведущие нули:
000000001
000000010
000000100
000001000
000010000
000100000
001000000
010000000
100000000
Не понятно что тут происходит? Читай три поста про битовые операторы начиная с этого ➡️https://t.me/pythonotes/45
В общем, это пример применения побитовых операций в самом Python.
Теперь вы знаете Python еще немного лучше)

COCCIDIOSIS
Coccidiosis is a deadly disease that hampers chicken's productivity and welfare. Thus, the disease is a major menace to the global poultry industry. Coccidiosis which is caused by the apicomplexan parasite of the genus Eimeria has seven known species which affect the different parts of the intestinal tract of chickens
#SIGNS
Common signs in infected flocks include
*reduced feed consumption,
* rapid weight loss,
* droopiness
* ruffled feathers,
* severe diarrhea.
* Wet droppings with mucus
* Clinical infections are seldom seen in poults >8 wk old. Morbidity and mortality may be high
#TREATMENT
The most popular treatment for coccidiosis is #Amprolium, which blocks the parasite's ability to uptake and multiply. Treatment is usually administered by adding Amprolium to the chickens' water supply, however in some cases, where sick chickens aren't eating or drinking enough, the medication is given orally.

Cow Calves Mites Infestation:
*******
#Mite_infestations in calves are usually caused by sarcoptic mange (Sarcoptes scabiei) or
chorioptic mange (Chorioptes bovis).
These mites cause
intense itching,
hair loss,
scabs, and
thickened skin, especially around the
head,
neck,
legs, and
tail base.
#Symptoms of Mite Infestation in Calves:
Severe itching and restlessness
Hair loss and crusty skin lesions
Thickened, wrinkled skin
Reduced weight gain due to stress and discomfort
Secondary bacterial infections if untreated
#Diagnosis:
Skin scrapings examined under a microscope
Clinical signs and response to treatment
#Treatment Options:
1. Topical Treatments:
Lime sulfur dips
Amitraz or permethrin-based sprays
Ivermectin or doramectin pour-on treatments
2. Injectable Treatments:
Ivermectin (SC or oral): Effective against both Sarcoptes and Chorioptes
Doramectin or Moxidectin
3. Environmental Control:
Clean and disinfect calf pens
Avoid overcrowding
Treat all animals in the herd to prevent re-infestation
#Prevention:
Regular parasite control programs
Monitoring new animals for signs of mites
Ensuring good nutrition and overall calf health

‘Heart Water’ Disease:
*******
Heart water also known as
1. Cowdriosis
2. Nintas
3. Ehrlichiosis.
Heart water is a ricketsial disease of ruminats and some wild animals include cattle sheep and goats ans deer in domestic animals the incubation period varies because of dependent of their rout infection and age.
...................#Etiology....................
its a tick born rickettsial diseases caused by Ehrilichia ruminantum (foremaly known as cowdaria ruminuntum)
its transmitted by tick genus of Ambylomma
#NB cowdariosis is a notifiable disease.
.................#Clinical#Sign..................

* Tremor
* head pressing

* Tachycardia
* Muffled heart sound
5. Very hard kicking
6. Oedema and diarrhoea.
...................#Diagnosis.......................
#Post-#Mortum#Examination.
1. a light yellow transudate found
* Thorax
* Abdomen
* Pericardium.
2. Pulmonary oedema
3. Most fetal cases is
* Hydropericardium
4. Difinetly diagnosis you have to focus.
* Hippocampus (Under gemsa stain ) or histopathology
.......#Differential#Diseases.( look like ).......
1. Toxic plant
2. Tetanus ( just look for wound )
3. Listeriosis.
4. Milk fever (but remeber its depends muturation during or after parturaion)
5. Mineral deficiency
6. And more others related muscles.
..............#Control. (Vector control ).................
(Amblyomma hebraeum)
1. Ectoparasiticide
control tick those cause diseases specially thse species
* Boophilus
* Hyalomma
.................#Vaccination (young once ).............
