METHODS OF DRUG ADMINISTRATION IN DISEASED POULTRY
Commonly used drugs include – antibiotics, anticoccidial, growth promoters

In Drinking Water :
ADVANTAGES > there is no delay in administration or withdrawal. Birds may continue to drink when sick and “off feed”.There is prompt absorption and is also very convenient to use.

Topical Spray or Dust : ( for Ectoparasites) 

Egg Dipping: Must be done at the hatchery under controlled conditions. Usually results in reduced hatchability or fertility (e.g. antibiotics to control egg transmissible diseases such as mycoplasma.

Individual Bird Injection : necessary in severe disease or when drug of choice is non-absorbable (e.g. antibiotics). It is also labour intensive and time consuming

In Feed: Often used in preventive or long-term medication. Must be done when mixing feed and requires planning so that delivery and storage on the farm does not delay treatment.

@vets delight DRY COW THERAPY : dry period (drying to calving: 60days) The dry period should last for about 60 days irrespective of whether the cow is still producing a lot of milk. Attempts should be made to minimize stress to the cow during the drying especially for high yielders. Ways of drying cows:  • The feed intake should be reduced to maintenance level by withdrawing the concentrates and for high yielders, feed on low quality forages (eg straw) to reduce milk synthesis. • For low yielding cows, just stop milking. Pressure builds up in udder and milk production is cut off. • If cow is a high yielder, practice intermittent milking i.e. skip some milking times (milk only in mornings) so as to reduce milk synthesis due to pressure build up in udder while reducing feed intake. • Water can be temporarily withdrawn for very high yielders to reduce milk synthesis. • After cessation of milking, treat (infuse) all the quarters with long acting antibiotics to ...

Dairy cattle nutrient requirements

-
©vets delight Major nutrients required to feed a dairy cow so that  she will not only produce good yields of milk for 250 days but also  have a calf every year The two major nutrients are Energy (which comes from carbohydrate in the form of sugars, starches, cellulose and hemicellulose found in plants and their seeds) Protein, also found in plants and their seeds. The other nutrients are vitamins and minerals but they will be found naturally in most plants and if not, can be supplemented quite cheaply. Thus it is important that plants fed to cows are high in energy or protein or preferably both. Natural (veld) grass only has these for the cow for about three months of the year in the rains. After that they are not good enough for good milk yields and good fertility and furthermore, by September, there is often not enough grazing for the animals, especially in a dry year. Commercial dairy concentrates have energy derived from maize and maize by-products and pr...
