Topic 8: Livestock Physiology

Define the term Artificial Insemination 

.Is the introduction of semen directly into the female reproductive tract through means other than copulation.


Procedures of artificial insemination of cow


Discuss the advantages of artificial insemination 

There are several advantages by artificial insemination over natural mating or servicing:

.There is no need of maintenance of breeding bull for a herd; hence the cost of maintenance of breeding bull is saved.

.It prevents the spread of certain diseases and sterility due to genital diseases’: contagious abortion, vibriosis.

.By regular examination of semen after collection and frequent checking on fertility make, early detection of interior males and better breeding efficiency is ensured.

.The progeny testing can be done at an early age.

.The semen of a desired size can be used even after the death of that particular sire.

.The semen collected can be taken to the urban areas or rural areas for insemination

.Old, heavy and injured sires can be used.


Disadvantages of Artificial Insemination


.Requires well-trained operations and special equipment.

.Requires more time than natural services.

.Improper cleaning of instruments and in sanitary conditions may lead to lower fertility.

.If the bull is not properly tested, the spreading of genital diseases will be increased.

.Necessitates the knowledge of the structure and function of reproduction on the part of operator.

Topic 6: Principles of plant growth

  Explain the concept turgor and plasmolysis Define the term Tugor Turgor pressure is the force exerted by fluid inside a plant cell that pushes the cell membrane against the cell wall, contributing to the rigidity of living plant tissue.  .This pressure is crucial for maintaining the structural integrity of plants, allowing them to stand upright and maintain their shape.  .A loss of turgor pressure, typically due to water loss, leads to wilting in flowers and leaves as the cells lose their firmness.  Define the term Plasmolysis Plasmolysis is defined as the process of contraction or shrinkage of the protozam of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature. Differences between Turgor and Plasmolysis  .Plant Cells: Plants are made up of cells that cooperate to support growth and structural integrity. The proper maintenance of energy and operation of these cells is greatly influenced by wa

Topic 4: Soil Types

Image
  Describe the main characteristics of Clay soil, Sand soil, and Loam soil Clay soils are heavy, high in nutrients, wet and cold in winter and baked dry in summer Characteristics   . Poor drainage  . Difficult to cultivate because the soil is sticky when wet. . High organic content . Poor aerated due to particles closely packed together  . Has blocky structure  Sandy soils are light, dry, warm, low in nutrients and often acidic Characteristics   . Low water holding capacity  . Low fertility . Fast drainage because of large particles  . Easy to cultivate  . It is structureless   Loams are mixtures of clay, sand and silt that avoid the the extreme of each type.                                    Loam soil Characteristics   . Right amount of air . Rich in organic matter . Easy to cultivate  . It has a crumb structure Click on the link below for more videos! Thank you!   https://youtu.be/QtwMIIRX8TM?si=g14H82VkPad9FtEn
