Description
As part of nutritional management of horses you need to know the dietary intake of the horses that you manage. As part of the practical class requirements you will undertake pasture evaluation, collection and analysis. Based on these calculations you will determine the daily requirement for lacating mares and determine any supplementary feeding required in addition to the pasture that is available to the mares. A detailed document for this assessment will be provided at the practical class.

files updated The excel is the data we collect from our feeding paddock, and the data is not completed calculated, you have to calculate and have the mean value of each group of data, then compare to the " Feeding value of pastures for horses", and have a discussion (see the detail in "ANIM3030/7117 Equine Nutrition and Health (Internal and External) 2018") Its like a lab report, and here is the instruction PRACTICAL CLASSES In these practical classes you will undertake a number of activities to assess the quality of pastures. 1. Pasture collection Samples will be collected from two different pastures used to graze horses. From these you should be able to determine an estimate of the quantity of pasture available on a per hectare basis. 2. Chemical analysis of pasture and concentrate samples The samples will be analysed for dry matter (DM), organic matter (OM), crude protein (CP), ash, acid detergent fibre (ADF), neutral detergent fibre (NDF) and minerals. From the raw data given in the sheets provided, complete the calculations for the different nutrient classes. This data will give a good assessment of the quality of the pasture. 3. Calculate the daily ration for a lactating mare Calculate the nutrient content of the pasture and concentrate. Estimate the amount of available pasture and the daily feed intake of mares with foals at foot that are aged 1 to 4 weeks. We will assume that we have samples a 2h paddock and base our calculation on that. Determine how many mares with foals at foot you could reasonably graze on each of the 2 paddocks. You have a concentrate available. If you do feed this how much would you feed and what time of day? Should minerals be supplemented? Assume that the mares have free access to pasture, weigh 500kg, are in the 1st month of lactation and you need to maintain them at the same body condition score.

Introduction
Horses need the balanced diet for the better performance. The optimal management of the horse
should be held at a particular level regardless of the use of the horse. Feed is done to maintain
horse healthy capable of performing its desired tasks. The diet includes all essential nutrients in
correct ratios and amounts as their health varies with nutrients delivering and management of
feeding program.
The understanding of their digestive tract anatomy is needed for adequate discussion of the horse
diet needs. Feed passage from mouth through the stomach and small intestine is very rapid. It’s
affected by various factors main one been the particle sizes. When food is ground or chewed the
rate of digestion increases. Therefore selection of feeds which are easily gradable or chewable
will make the animal perform better and be healthy.
In addition to this, nutrients in the feed for support various body functions. The main classes of
nutrients are energy, water, protein, minerals and vitamins. Water is crucial in the diet as it
assists in the regulation of body temperatures. Water consumption depends on environmental
temperature and humidity, exercise, stage of lactation and kind of feed. However, the animal can
live fewer days without water compared to days without other nutrients.

In addition to this, a horse needs energy. Energy is obtained from carbohydrates, fats and
sometimes proteins (in times of starvation). Due to abundance in many plant feeds,
carbohydrates are sources of energy. Main carbohydrates are sugars and starches, which are
easily absorbed and cellulose which take long to be digested/absorbed. Energy is used for
growth, milk production and body repair as well as powering the main body activities- energy is
fuel for all physical activities.
Proteins are consumed in muscular activities, growth, lactation, skin hair development, worn out
body tissues repair and even reproduction. In starvation, they become sources of energy.
However, consideration of the protein quality is always prudent.
Vitamins have varieties of body roles, more often are metabolic catalysts. Their classification is
into two: fat soluble such as A, D, E and K. They can be stored in the body and utilised in the
future. Then we have water-soluble vitamins which cannot be stored they include B complex
vitamins. Generally, a good diet of green hay, cereals and sunlight provide a reliable supply of
vitamins.
Minerals are mainly available in diet depending on soil and water in the area, food quality and
grain hay proportion in the diet. The main type of mineral is macro minerals such as calcium,
sodium, chlorine and phosphorous.
Discussion
In this regard, we have to check the quality of the feeds keenly so that we attain good
performance of our animals. In this paper, we are going to examine various types of feed
depending quality and quantity of these parameters.
