Worked Solution & Example Answer:The diagram below represents the udder of a dairy cow - NSC Agricultural Sciences - Question 4 - 2017 - Paper 1
Step 1
The graph shows information on the development of the udder's size over a dairy cattle.
Answer
The graph indicates an increase in the size of the udder as the dairy cow matures. This growth is essential for the production of milk, which is crucial for the nutrition of calves and for milk production purposes.
Step 2
Growth and development of the udder normally take certain forms.
Answer
The growth and development of the udder typically occur through a combination of hormonal stimulation and physical changes. Initially, there is an increase in the number of alveolar cells, which are critical for milk production. Moreover, as the cow approaches lactation, vascularization and the expansion of connective tissues are necessary for efficient milk storage.
Step 3
Step 4
Name the hormone responsible for: Growth and development of Graafian follicles.
Answer
The hormone responsible for the growth and development of Graafian follicles is Follicle Stimulating Hormone (FSH). FSH promotes the maturation of the ovarian follicles, which is crucial for ovulation and subsequent reproduction.
