HEATIME, A TECHNOLOGY IN EVOLUTION Do you own a smartphone? If yes, there’s a good chance that it’s an iPhone or an Android. Which version are you holding in your hands? It seems that the launch of new versions is endless. The hi-tech industry is progressing at a very rapid pace and the agricultural world is no exception, and this, to the benefit of producers. Closer to home, Heatime has undergone major changes and is constantly improving to better respond to producer’s expectations. The Heatime system is the only one in the world designed for both free and tie stalls. SCR Dairy (Allflex), in partnership with Ciaq, has carried out a research for over two years to develop tag sensors for cows in tie stalls and to improve the original version. The behavioural study on cows in tie stalls resulted in the development of a distinct algorithm that detects the movements of a tied cow in heat. SCR Dairy now has tag sensors programmed to respond to the environment in which your animal is housed. The rate of heat detection has increased 10-15% with new tag sensors programming for tie-stall cows based on the environment in which they are housed. HEAT DETECTION Service rate x Conception rate = Pregnancy rate (Point de vue, January - February 2016, Landry, Ménard) Breeding and production success is the result of this very simple equation. The easiest variable to influence is the service rate. Top managers spot 60% of heats from visual detection and the average is about 40%. The top performing tool on the market to help producers detect cows in heat and reduce the number of open days is the Heatime heat detection system. With 70% of the world market, the Heatime system, is an excellent tool to measure the activity of a cow or heifer, and its rumination rate. According to a study carried out in 2011 by Rafael C. de F. Neves, the system allows for better heat management and results in a 93.5% rate of heat detection for cows in free stalls. The system is fully configured for monitoring right from the time of installation. Here is what one of the main screens looks like. The green line outlines any activity change of the selected animal and the purple line is its change in rumination rate. An increase in activity parallel to a decrease in rumination represents the onset of a heat. The two heats in question can be clearly seen and the system algorithm analyzes each cow individually based on its usual activity. 16 POINT DE VUE NOVEMBRE - DÉCEMBRE 2016

By Matt Delisle, Dairy Solutions Specialist RUMINATION Rumination is also a key element of the system. A cow’s health is reflected in a direct line to its rumination; if there is a noticeable drop in the rumination rate then something is happening to the animal. If you have tie stalls, it is very easy for you to see if a cow consumes all or just part of its feed. But what about those with free stalls? It is very difficult, if not impossible, to measure the voluntary intake of dry matter in this type of housing. Producers must question themselves when one of the cows does not consume its feed. The Heatime system therefore becomes an effective tool to help you carry out this analysis. A study by Cornell Univer sity demonstrated that 68% of cows show signs of heat between 6:00pm and 6:00am. Times cows show signs of heat 6 a.m. - noon 22% Noon - 6 p.m. 10% CHANGES AND HEALTH 6 p.m. - midnight Midnight - 6 a.m. 25% 43% Source: Cornell University The monitoring component is an essential part of the Heatime system. How do you measure the fact that a freshly calved cow is progressing more than another? Knowing that you are already investing a significant amount of money for treatment. Wouldn’t you be interested to know if the treatment is working well, and know the pace at which your cow is reacting positively? The Heatime system responds readily to all of these questions through the individual monitoring of each cow equipped with a tag sensor. A ruminating cow with an increase in the frequency of her heart beat is making progress and can be expected to get better. For all kinds of situations, Heatime is an excellent indicator! If you want to be proactive rather than reactive in the management of your dairy operation in an environment that currently presents enormous economic challenges, then let us help you simplify the task with a Heatime system; you’ll be incredibly happy with the results! Testimonial of Martin Henderson of DFM Henderson Farm in Saint-Chrysostome, a producer who participated in the research program: "Two months after the installation of the new Heatime tag sensors, we did pregnancy checks on 32 cows. We had 28 positive tests and 24 of the 28 were due to Heatime. Before this, 85% of our cows were on synchronization protocols and with the new tag sensors this has dropped to less than 10%. With Heatime, the timing for service is more accurate and the system saves me time and lowers my health costs. The use of Heatime is very easy and the rumination report helps me monitor my fresh cows and balance my rations." POINT DE VUE NOVEMBRE - DÉCEMBRE 2016 17
