Weak and big belly calve
identifying potentially unwell Calves
Step 1: pick out calves wanting more cautious assessment at and just earlier than feeding times.
component 1: reaction to calves at feeding time.
in case you solution "no" to a query under, look at these calves greater carefully using the questions indexed under Step 2: nearer Inspection.
Does the calf rise up and actively function itself at its milk feeding station?
Does the calf want to drink its milk?
Does the calf drink its milk at its ordinary predicted fee?
With computerized feeding stations, does the calf drink its regular allocation of milk within the allocated time body?
Are the calf’s ears erect, and is the calf alert? Droopy ears are a signal of illness (See Fig. 1).
discern 1. An alert calf with erect ears.
parent 1. An alert calf with erect ears.
part 2: extra observations at each feeding.
If any problems are detected, calves need to be tested more carefully the use of the questions listed underneath Step 2: closer Inspection.
what's the calf's manure consistency?
take a look at the outline that is the nearest. Calves which can be scouring need extra fluids and need to be tested more carefully and need to be fed closing to prevent unfold of diseases to healthy calves.
Pudding consistency – normal fecal consistency
Yogurt consistency – fecal consistency does no longer warrant feeding electrolytes
Maple syrup consistency and/or strong scent – too skinny. Calf needs nearer examination, and electrolytes have to be fed similarly to and separately from milk.
Apple juice consistency – too thin. Calf wishes closer exam, and electrolytes should be fed in addition to and separately from milk.
Is the calf coughing and/or has a discharge from its nostril or eyes? if so, nearer examination of the calf is wanted for potential respiration illnesses. Your veterinarian allow you to diagnose the source of the hassle and prescribe the great route of movement. Antibiotics need to be used as directed with the aid of your neighborhood veterinarian.
Step 2: nearer Inspection (for calves with ability infection detected through questions answered in Step 1)
Calf’s essential signs or physical Measurements
If a calf’s important signs are outside the ordinary range (this is, you have got spoke back "sure" to any query), put in force remedy protocols that have been evolved with the assist of your local veterinarian.
regular or anticipated calf vitals
Is the calf’s temperature elevated? one zero one° to 103°F is regular
Is the calf respiration rapidly? 24 to 26 breaths per minute is everyday in calves much less than 1 month of age and 15 to 30 breaths in step with minute in older calves
Is the calf’s coronary heart price extended? one hundred to 140 beats per minute is ordinary in calves (two times as rapid as a cow). An abnormal heart beat is one sign of contamination.
Are the calf’s eyes sunken into the eye socket? (lightly evert the calf's lower eyelid and examine the amount of space between the eyeball and the decrease eyelid.) healthful calves have a minimum amount of space among the lower eyelid and eyeball (less than 2 mm or a touch greater than 1/sixteenth of an inch). because the calf turns into dehydrated, the amount of space between the eyeball and lower lid increases. (See Fig. 2)
whilst the pores and skin of the neck is pinched and gently rotated ninety°, a tent of the pores and skin paperwork. Does this skin tent return to normal within 2 seconds? (See Fig. 3) generally, count on the tenting of skin to return to normal within 2 seconds.
Are the calf’s gums dry and white? typically, a calf’s gums are wet and pink. Dry, white gums are a symptom of intense dehydration (8-10% dehydration).
If the calf is mendacity down, does it fail to stand up when given a small quantity of persuasion? For calves that are not able to upward thrust, contact and/or observe your veterinarian’s pointers without delay. these calves may need IV fluids (fluids administered at once into the blood) to help deal with the dehydration and feasible acidosis. If now not treated correctly and fast, this calf can also die.

Electrolytes important for Scouring Calves
Calves can lose 5% to 10% of their body weight day by day in fluids because of scours. To replace those misplaced fluids, electrolytes ought to be fed further and one by one to the calf’s allocation of milk. Electrolytes on my own do no longer provide an good enough amount of electricity for the calf to combat off the ailment and preserve frame weight. To determine if extra treatments (i.e., antibiotics) are had to assist the calf get over scours or pneumonia, farmers need to paintings with their nearby veterinarian to increase remedy protocols that reflect the needs and illnesses seen on their dairy operation (referred to as fashionable running procedures, or SOP).
each day amount of electrolytes needed for a hundred-lb calf**
total daily quantity of fluids (milk plus electrolytes)
robust suckling reflex
skin tent returns to everyday in less than 2 seconds
three quarts of electrolytes plus 4-6 quarts of milk
Calf still has sucking reflex
pores and skin tent returns to regular in 2-6 seconds
moderate depression; calf may be vulnerable
6-eight% (fairly dehydrated)
4 quarts of electrolytes plus 4-6 quarts of milk
Calf mendacity down; rises most effective when advocated
pores and skin tent returns to ordinary in greater than 6 seconds
Very sunken eyes; white and dry gums
Calf depressed; calf can be weak
eight-10% (critically dehydrated)
IV fluids had to offer good enough fluids and to accurate blood pH as a result of imbalance of acids and bases inside the blood (referred to as metabolic acidosis)
contact veterinarian and observe his or her advice
* Overfeeding electrolytes causes little detriment to calves. but, underfeeding electrolytes can prolong scours and not accurate the dehydration and lack of electrolytes.
** The range of quarts of electrolytes wished similarly to the fluids from milk is identical to
((Weight of the calf * (% dehydration/one hundred))/2)
