SELECTION OF DAIRY CATTLE 
Proper selection is the first and the most important step to be adopted in dairying. Records are the basis of selection and hence proper identification of animals and record keeping is essential. Cross-breed animals with exotic inheritance of about 50 percent are preferable. This preference is based on comparison of the performance of the animals with different percentage of exotic inheritance. Fifty percent of the native germplasm is helpful to retain the adaptability, heat tolerance and disease resistance traits of local animals, in cross breeds. The utilization of the Zebu (Sahiwal) germplasm in the formation of breeds like Australian Friesian Sahiwal (50% of Holstein and 50% Sahiwal) and its international recognition as a breed for the tropics is an example.

Maintaining animals sustainable to the situation is the best policy. Bringing animals from different agro-climatic conditions causes problems due to non-adjustment in many cases. In case, purchase becomes absolutely essential it should be from similar environmental conditions as far as possible.

• The maximum yields by dairy cows are noticed during the first five lactations. So generally selection should be carried out during First or Second lactation and that too are month after calving.
• There successive complete milking has to be done and an average of it will give a fair idea regarding production by a particular animal.
• A cow should allow anybody to milk, and should be docile.

Selecting breeds for Commercial Dairy Farm - Suggestions

• Under Indian condition a commercial dairy farm should consist of minimum 20 animals (10 cows, 10 buffaloes) this strength can easily go up to 100 animals in proportion of 50:50 or 40:60. After this however, you need to review your strength and market potential before you chose to go for expansion.
• Middle class health-conscious Indian families prefer low fat milk for consumption as liquid milk. It is always better to go for a commercial farm of mixed type. (Cross breed, cows and buffaloes kept in separate rows under one shed).
• Conduct a through study of the immediate market where you are planning to market your milk You can mix milk from both type of animals and sold as per need of the market. Hotels and some general customers (can be around 30%) prefer pure buffalo milk. Hospitals, sanitariums prefer cow's milk.

Selection of cow breeds for commercial farm:

• Good quality cows are available in the market and it cost around Rs.1200 to Rs.1500 per liter of milk production per day. (E.g. Cost of a cow producing 10 liter of Milk per day will be between Rs.12, 000 to Rs.15, 000).
• If proper care is given, cows breed regularly giving one calf every 13-14 month interval.
• They are more docile and can be handled easily. Good milk yielding cross breeds (Holstein and Jersey crosses) has well adapted to Indian climate.
• The fat percentage of cow's milk varies from 3-5.5% and is lower then Buffaloes.
