One thing like a Jersey cow, which many dairy farms additionally maintain as a result of excessive butterfat content material of their milk, can produce anyplace from 1 to six gallons of wealthy milk per day.
Steps to extend Cow Milk Production
Past the weight-reduction plan, rearing circumstances and herd administration have a direct influence on the quantity of milk produced per cow per day. Step one to be carried out consists of enterprise an audit. The conclusion drawn from this audit will assist determine areas for enchancment.
This course of will take varied elements into consideration : diet, well being, environmental and herd housing by specializing in the next factors:
Administration of reproductive points: poor reproductive efficiency will increase the calving to calving interval and, due to this fact, the common size of lactation. As a direct impact, low reproductive efficiency can forestall the weight-reduction plan from being totally utilized.
Management of well being points: the assorted illnesses generally encountered in dairy herds can scale back the effectivity of digestion (ketosis, acidosis, fatty liver, alkalosis …) and trigger issues in consuming behaviors (acidosis, lameness) in addition to have an effect on secretory tissues (mastitis …).
Housing circumstances: housing should favor a greater expression of the complete potential of animals’ habits. Animals ought to have everlasting entry to the feed bunk and consuming water. Applicable housing should additionally forestall the emergence of illnesses inherent to rearing contexts (the significance of air flow, brightness, of bedding high quality, of stalls setting…).

the gross sales worth: this worth extremely relies upon in the marketplace and alternatives obtainable on the farm. Certainly, sure levers on the farm stage can enable for increased earnings. The primary entails the command of milk composition with regard to exploit solids (fats and proteins). The second lever pertains to the command of milk high quality for avoiding possible dangers (germs, somatic cell depend …). These two levers can maximise the value of every ton of milk.
Optimisation of the weight-reduction plan: enchancment of the Milk Index, or the quantity of milk produced per kilogram of dry matter consumption, is more likely to generate a excessive return on funding contemplating the preliminary feed prices engaged.
The management of upkeep charges: some upkeep prices are proportional to the variety of animals current on the farm. These prices embody the next: authorized constraints for the management of manure, animal housing and milking gear wanted to make sure respectable working circumstances, employment prices…. Boosting the productiveness per cow ensures a greater return on funding of those charges.
