Learning outcomes

On completion of this module, students should be able to:

Analyse common feeds

Interpret the results of feed analysis

Describe the current feeding standards used in animal nutrition

Formulate rations for ruminant livestock and horses

Outline the principles of Mendelian genetics using examples from domestic livestock and discuss their application to breeding for coat colour, and the control of lethal or deleterious conditions with Mendelian inheritance.

Apply the basic concepts of quantitative genetics.

Describe national breeding schemes for domestic livestock and evaluate aspects of their design that influence the rate of genetic improvement for metric traits.

Brief description

The lecture course involves a study of the present and previous feeding standards used in animal nutrition, leading to a discussion of ration formulation and the analytical techniques required for feed evaluation. The animal breeding component of the module will investigate Mendelian and quantitative genetics, parentage testing, and the definition of selection objectives for successful breeding programmes.   Practical classes include the identification of various feed ingredients and the determination of the chemical composition of feedstuffs, which will enable students to formulate rations for ruminants and horses.


The primary aim of the new module is to develop an understanding of the principles of animal nutrition and animal breeding together with their application to the management of domestic farm animals and horses. The main aims are:

a. To develop an understanding of the importance of feed analysis and its limitations for efficient animal nutrition.
b. To outline the principles of ration formulation for ruminant livestock and horses and to apply the current feeding standards.
c. To outline the principles of Mendelian and quantitative genetics in animals.
d. To define selection objectives and discuss problems in the evaluation of breeding value in the genetic improvement of performance in horses and farm livestock.

Module Skills

Improving own Learning and Performance Will be developed and assessed in both the written assignment and examination.  
Application of Number The successful formulation of rations for horses and livestock involves the use of relatiely complex equations and ideas in order to establish nutrient and energy requirements and allowances. These will form an integral part of the feed evaluation/ration formulation assignment and will be assessed at that point. Animal breeding requires an understanding of statistical concepts such as probability, variance, regression and correlation. Skills in the use of numerical information will be developed during lectures and practical classes, and will be assessed by examination.
