This document describes the clinical signs and treatment of various types of mastitis in cattle. Peracute mastitis is characterized by severe systemic reaction and painful, hot swelling of the udder with blood-stained milk. Acute mastitis presents as painful udder swelling with changes in milk consistency and pus. Chronic mastitis results in udder fibrosis and atrophy with milk clots. Treatment involves intramammary antibiotic infusion and supportive therapies like anti-inflammatories and cold therapy. Prognosis depends on mastitis type, with staphylococcal having poor response to antibiotics.

2. Clinical signs
1-Peracute mastitis:
*severe systemic reaction (fever , anorexia , depression(
*painful & hot swelling of the the udder
*blood stained milk secretion
*recumbancy due to toxamia
2-Acute mastitis
*painful , hot swelling of the udder
*change in consistancy of milk , presence of flakes or
pus
*swelling of supramammary L.N

3. 3-Chronic mastitis:
*fibrosis & atrophy of the udder
*change in milk in the form of clots
4-streptococcal mastitis: ch` by:
*fever
*inflammation of the udder
*watery milk
5-staphylococcal mastitis: ch` by:
*severe systemic reaction
*severe swelling of the udder
*gangrene & sloughing of the affected quarter
may occur after 1 week
*poor in its response to antibiotic

4. 6-coliform mastitis: ch` by
*more common around calving ch` by peracute form
7-Tuberculous mastitis: → chronic disease , ch` by:
*induration of the udder
*enlargement of supramammary L.N
*milk contain fine flocules → settle down after milk left
stand → clear amber color
8-mycoplasma mastitis: ch`by
*sudden onset
*involvement of all quarter
*severe swelling of the udder
*milk contain granular deposite (fine sandy material &
flakes) → after milk left stand → turbid whey
supernant
*complet cessation of milk secretion

5. 9-pasteurella mastitis: common in sheep , ch` by:
*systemic reaction
*acute swelling of the udder
*watery milk
*the udder become blue & cold (gangrenous mastitis)
10-Mycotic mastitis:
)1(in case of cryptococcus:
*swelling of udder & supramammary L.N
*severe ↓ in milk yield
*section of viscid mucoid gray white secretion
)2(in case of candida
*fever
*severe inflammation of udder
*swelling of supremammary L.N
*presence of large yellow clots in watery fluid

6. (3)in case of aspiragillus:
*presence of abcesses in udder surrounded by fibrous
tissue
**D.D: from:
1-physiological edema:
*occur after calving
*painless swelling of the udder & edema may extend
along abdomen
*normal ch` of milk + blood from 1 quarter
*it disappear within 2-3 days
*it responds rapidly to diuretics

7. 2-Bloody milk dut to leptospira
*flaccid udder & flappy
*the blood come from all quarter
*no inflammation of the udder
*has bloody urine
3-bloody milk due to truma:
*blood only without milk
*treatment of trumatic bloody milk:
1-I/ mammary infusion of epinephrine alone or with
saline (1 - 2 amp.(
2-I/V injection of Cal-D-Mag → 50-100 cm
3-I/M injection of Vit.K→ amri K 1 amp. / 70 kg B.wt
4-cold application

11. Treatment of mastitis:
1. I/M injection of panTerramycin → 1cm/10kg b.wt /24 hr / for 5
successive days or streptopencid → 2 vial /12hr / I.M / 5 days
(in case of systemic reaction
only)
2. Udder infusion with antibiotic (in mastitis drug – in drug index)
N.B :
*It is very necessary to evacuate the quarter before infusion of
the drug I/mammary
*make massage for the udder after drug infusion
*milk from treated cows must be not used for human
consumption for a period of time (acc,. To the used drug)
3. Drying off the chronically affected quarter by produce chemical
mastitis by :
-udder infusion of 30-60 ml of silver nitrate solution or
copper sulphate 5 %
or 100-300 ml of acriflavin solution 1/500

12. 4- supportive treatment :
*I/V injection of glucose 25% → 1-2 liter
*I/V injection of Avil → 1 amp./70 kg B.wt
*local application of cold fomentation (ice bag) on the
udder(in acute cases)
