Heifer care and management
Department Publishes Overview of Heifer Raising Industry

The report, which is a cooperative effort between the Animal and Plant  Health Inspection Service (APHIS), the 21 participating States, and the  Dairy Calf and Heifer Association (DCHA), aims to give a snapshot of  how the industry was operating in 2011.
Because the capital costs associated with starting up heifer rearing  businesses are not large they often go in and out of business in a  relatively short time. Despite the transient nature of the business,  gauging how this industry works is important as they contribute to the  Dairy sector greatly by freeing up space and time on other farms for  lactating cattle and milk production. 
 
Report Findings
Logistical and Business Observations
The challenges faced according to the report were principally; stock  health, client relations, receipt of payments; and cost and availability  of feed. These challenges were new to the majority of operations as  most farms had been involved in the industry less than ten years. In  fact, only 10 per cent of operations could boast of more than 21 years’  experience in the business.  
For the surveyed enterprises in 2011, most heifers were returned to  the dairy of origin although about 20 per cent of heifers were sold  through auction markets, dealers or directly to other dairies. The age  heifers were sent from original dairies varied greatly from two days old  to heifers that were pregnant.
Health
Understandably, heifer health was the main concern amongst operations  managers with digestive problems and pneumonia being the most common  disorders affecting pre-weaned heifers. Antibiotics were used to treat  pre-weaned heifers on 85 per cent of operations. 
The two most common health issues affecting weaned heifers were  diarrhoea and respiratory problems. The survey showed that 82 per cent  of operations treated respiratory problems in calves with antibiotics.
Feeding Practices
The results of the report emphasised the importance of administering  colostrum to new born calves and in all cases this was undertaken on the  dairy of origin. 
Once in the heifer rearing systems 85 per cent of farms fed milk  replacer to calves. The report concluded that of farms that administered  medication in milk replacer Oxytetracyline in conjunction with Neomycin  was the most common. 
Despite concerns about the use of antibiotics in livestock feed three out of four operations fed antibiotics to heifers.
Disease Transmission
Due to risks of TB, Brucellosis and Salmonellosis transmission the  USDA opposes the mixing of different heifers from different dairies of  origin. The survey showed that 60 per cent of operations allowed heifers  from different dairies to mix. On 20 per cent of operations nose to  nose contact was possible. 
The report observed the operations, monitoring them for disease carrying  wild animals. Foxes, coyotes, deer and raccoons were sited on nine out  of ten enterprises. The USDA consider these animals as a threat to  agriculture and consider Raccoons a potential source of rabies and  Salomella and associate Foxes with Leptospirosis and Neospora. 
The department stated that because breeding can spread Bovine  Leukaemia Virus and Trachiomoniasis insemination methods used by the  enterprises had implications on disease management. Of the farms  surveyed 75 per cent bred heifer on site with 18 per cent using natural  breeding. Half of farms used a combination of artificial semination (AI)  and bulling and 30 per cent used AI only.
