Israeli design forms basis for modern South African farm

Israeli design forms basis for modern South African farm

The most southern province of South Africa is called Western Cape. This region has the largest dairy operations in the country as well as the most registered Holsteins. Because the area is not suitable for the production of high-quality forage, they are very focussed on performing as well as possible in all aspects – here is their story.

The Multifactorial Approach to Fertility Problems

The Multifactorial Approach to Fertility Problems

Feeding for efficient milk production leads in modern dairy practice. Efforts to maintain production and fertility at optimal levels under given market, husbandry and feeding conditions, often fail. Yet, financial
losses for an “open day” are estimated in various studies to be 2.5 to 5.0 US$.

Importance of Estrus Detection on Dairy Farms

Importance of Estrus Detection on Dairy Farms:

On the dairy estrus detection is the deliberate act to monitor and record the event of estrus and if artificial insemination (AI) is the method of reproduction, the breeding of the cow takes place at this time

Fertility Report in AfiFarm program and efficiency of Estrus detection

The fertility reports of the Dairy Records Processing Centers in some countries, including Israel, contain data about distribution of the length of the cows’ cycles in the herd. The percentage of “double cycles” (36-60 days) indicates above all the efficiency of heat detection.
The lower the percentage of double cycles, the greater the efficiency of heat detection. According to the HACHAKLAIT – the cooperative society for veterinary services – the goal of Israeli dairy cows’ reproductive management is less than 18 percent of double cycles.

Automated Monitoring of Dairy Cows’

Automated Monitoring of Dairy Cows’

Automatically monitored behavioral (feeding and locomotor) irregularities of Israeli Holstein cows were investigated in three dairies in relation to animals’ health status and stress conditions. Feeding behavior patterns were analyzed on the base of automatic on-line recording of feeding events. Indices of feeding behavior irregularities were proposed.
Long lasted feeding behavior irregularities were accompanied by poor health related parameters: higher milk Somatic Cells Count and conductivity, greater body condition loss toward first insemination, and increased cooling rate.

Proper control brings positive returns (Stuart Mackenzie)

Proper control brings positive returns

“About three years ago I was in an aggressive expansion phase. For me to get a good quota, I had to get my cow numbers up quickly. When I got the chance to acquire an Ayrshire herd, I not only could up my milk production, but it also offered me the opportunity to differentiate a little bit in terms of the price I receive for my milk, Ayrshire milk being regarded as different from Holstein milk.”
