Sam or Grant 881-0234 Skelton TemoriAs INDOOR SHOWROOM WALKERTON Measurement systems for cattle nutrition Energy is usually the first limiting nutrient in rations of high producing dairy cows. Energy is required in relatively large amounts and is required for body maintenance, milk production, reproduc- tion and growth. However, when a dairy ration is balanced some concerns that are often voiced are: "Is this feed good enough for maximum milk production?", "How much of this feed da I need to feed?", and 'How do I compare one feed to another?". Using energy measurement systems, like Total Digestible Nutrients (TDN) or Net Energy Systems, questions like this can be answered. - Before you can understand the dif- ferences between TDN and NE it helps to first understand what energy is, how it is measured and what units of measure are used. 1. What is Energy? Energy is the `fuel' that helps the body grow, maintain itself, as well as produce milk and a calf. Energy is not a simple nutrient like protein, car- bohydrates, vitamins or minerals and neither can it be measured directly in the lab like protein, fibre or minerals. Energy exists in the organic component of feed such as protein, fat and fibre, however, the amount of energy present in the feed and its availability to the animal will depend upon the quantity and quality of each com- ponent in the feed. Energy is not present in the inorganic component of feeds, i.e., minerals, nor is it considered present in vitamins as the amount of vitamins pre- sent is very small. 2. How is Energy Measured? Since energy is rather an `elusive' nutrient and is part of a lot of other nutrients, direct laboratory measurement is very difficult. To get around this problem, scientists have developed equations which estimate TDN and NEL from the fiber fraction of feed. Fiber can be measured directly in the laboratory as Acid Detergent Fiber (ADF). However, there is a catch: the only equations that the research community feel at the present time are accurate are those equations which estimate energy for hay, haylage and corn silage. Other equa- tions that estimate energy for feeds that WHITE BEANS We're ready when you deliver. W.G.

Energy values for such feeds as barley, barlage and soy- bean meal are derived from actual animal trials and are commonly referred to as "book values". Research is continuing in this area and soon all feeds will be able to be routinely analysed for energy. 3. What Units of Measure are Used? The units most commonly used in North America to measure energy are kilocalories (kcal). However, other units of measure that can be seen are calories (cal), megacalories (Meal) and kilojoules (KJ). Their relationship with each other is as follows: 1 kcal equals 1000 cal; 1 Mcal equals 1000 kcal; and 1 kcal equals 4.18 KJ. Energy can also be measured in terms of ration dry matter (Meal/kg) or as a percentage of the total ration or feed. 4. What is the difference between TDN and NE? Both systems measure energy, but the NE system is the more accurate of the two. The NE system is more precise and is composed of 3 categories; NE maintenance (NEm), NE gain (NEg) and NE lactation (NEL). The NE system therefore is divided into the amount of feed energy required for maintenance, gain and lactation. When formulating rations, the type of NE used will depend upon whether the animal is lactating or grow- ing. Lactating dairy cattle rations use NEI, while growing cattle rations such as for young heifers and growing and mature bulls use both NEm and NEg. TDN, on the other hand, is used for all classes of dairy cattle and has been shown to overestimate the energy available from roughages for botch milk production and weight gain. The TDN system has been used in the past, but if the dairy industry is to continue to strive for optimum production per cow and maximum feed efficiency improved systems such as the NE system mustbe adopted. Shared risk interest rate Farm Credit Corporation announced on August 29 that the interest rate on Shared Risk Mortgages (SRM) approved after August 26, 1988, has been increased to 12.75 per cent from the previous 12.25 per cent. Shared Risk Mortgages are funded by a combination of long and short term bor- rowings. While long-term interest rates have remained steady, short-term sates have risen making it necessary to increase the SRM lending rate. The interest rates on other loans offered by the Corporation are unchanged. Rates compared Federal Minister of Consumer and Cor- porate Affairs Harvie Andre recently released a table comparing features and costs of basic deposit accounts offered by major banks and trusts companies. This action fulfillls the Government's commit- ment to consumers to help them make in- formed decisions about banking services. "This table will provide consumers with access to the information they need to compare basic accounts and charges associated with them," the Minister said. The comparison chart covers the largest federally regulated chartered banks and the major trust companies. It is not ex- haustive but includes the main features of those accounts identified as basic in the agreement reached between the Govern- ment and Canada's financial institutions. Consumers are urged to shop and compare. "My Department will publish regularly updated tables of "n6 -frills" deposit ac- counts of financial institutions," Mr. An- dre said. "This information will assist consumers in making informed choices To obtain a copy of the comparative chart of basic deposit accounts, contact Consumer and Corporate Affairs Canada.
