Learning objectives
The course aims to enable the student to know and to understand the essential elements of morphological evaluation of farm animals, the methods of dairy cattle breeding, the different types of structures, the composition and quality of bovine milk, the main criteria of animal welfare, physioclimatology and farm hygiene.
This is also with the aim to develop the student's ability to use the knowledge and understanding gained in identifying the different problems that can occur in different types of dairy cattle farms.
The student, also, applying the knowledge and understanding acquired, must be able, also working with farmers and other professionals, to
- contribute to the proper management of a dairy cattle farm
- Contribute to the prevention of problems that can meet a dairy cattle farm
- Know how to detect and interpret the main parameters of a dairy cattle farm
Prerequisites
Prerequisites: 1005122 - Anatomia Normale Veterinaria and 1004812 - Zootecnica Generale e Miglioramento Genetico
Course unit content
The first part of the course is focused on morpho-functional evaluation of cattle: Regions in the head, in the trunk, in the fore legs and related defects, in the hind legs and related defects. First elements of animal mechanics and stance evaluation. Weighing and measurements. Morphologic evaluation.
The second part of the course focuses on breeding of dairy cows, calves and heifers. Also describes the different types of housing and the different types of milking systems.
The third part of the course takes into consideration the quantitative and qualitative characteristics of bovine milk, the different factors of milk variation and milk quality payment system.
The fourth part of the course is the morpho-functional evaluation of animals in livestock production.
The fifth part of the course focuses on animal welfare, analyzing the main cattle and pig welfare legislation and relations with the breeding structures.
The sixth part of the course deals with the principles of farm hygiene, the main methods of cleaning, disinfection and disinfestation and the general criteria of livestock biosecurity.
In the last part of the course will discuss the main concepts of physioclimatology, climate and microclimate, methods of measurement of climatic parameters, definition and calculation of THI.
During the course guided tours to dairy cattle farms will be carried out.

Teaching methods
During the lectures in the classroom, with the use of audio-visual facilities morphological evaluation of farm animals, the characteristics of dairy cattle farms, the properties of the milk will be presented. The course will be supported by visits to farms in order to make it clear to the student, through a direct experience in the field, the theoretical concepts discussed in the classroom.
The lessons will also be supplemented by seminars to deepen some specific issues.
Assessment methods and criteria
The assessment of the achievement of the objectives of the course is that the two modules are examined together. Therefore, the assessment of the achievement of the objectives of the course in its entirety provides a written examination followed by an oral examination, on a series of questions which will be previously provided to students at the end of each topic. Through questions regarding the course content will be determined whether the student has achieved the goal of knowledge and understanding of the content. The students must demonstrate that they have mastered the knowledge about the morphological evaluation of farm animals, on breeding of dairy cattle, on the physico-chemical and technological properties of milk, on animal welfare and on the general principles of farm hygiene. By means of the questions in the oral examination will be determined whether the student has achieved the goal of linking the arguments and to find solutions to problems, and if it proves to have good reasoning skills and independent judgment. It will be also assessed the appropriate specific language.
