Reference Materials

The following resources were used in planning this lesson:

9 Years Basic Education Curriculum (Senior Secondary Education) for Animal Husbandry.
State Unified Scheme of Work for Senior Secondary School Animal Husbandry.
Oyewole, A. (2018). Comprehensive Animal Husbandry for Senior Secondary Schools. University Press PLC.

Instructional Materials

The teacher will teach this lesson with the aid of:

Video screen or projector.
Videos showing parturition in different farm animals (e.g., cow, goat, pig).
Charts illustrating signs of approaching parturition.
Whiteboard and markers.

Rationale for the Lesson

This lesson helps pupils understand the practical aspects of animal birth, which is a key part of animal reproduction and farm management. Pupils will learn to identify important signs and observe the process, preparing them for real-life situations on a farm and ensuring proper care for animals.

Prerequisite/Previous Knowledge

Pupils have prior knowledge of animal reproduction, reproductive organs of farm animals, and basic animal management practices.

Lesson Content/Board Summary

Practical on Parturition

Definition of Parturition

Parturition is the process of giving birth in animals. It marks the end of pregnancy and the expulsion of the foetus from the mother’s uterus.

Signs of Approaching Parturition

The following are common signs indicating that an animal is close to giving birth:

Swelling of the vulva.
Relaxation of pelvic ligaments (making the tail head appear raised).
Development and distension of the udder (bagging up).
“Waxing” of teats (small drops of colostrum appearing on the teats).
Restlessness, pacing, or nesting behaviour.
Separation from the herd.
Loss of appetite.
Discharge of mucus from the vulva.

Observing Parturition

Observing parturition involves watching for the stages of labour and birth. The process generally involves:

Stage 1 (Preparation): Uterine contractions begin, cervix dilates, animal becomes restless.
Stage 2 (Delivery): Stronger contractions push the foetus through the birth canal. The water bag (amniotic sac) usually ruptures, followed by the appearance of the foetus.
Stage 3 (Placenta Expulsion): After the birth of the offspring, the afterbirth (placenta) is expelled.

A farm visit allows for direct observation of these signs and the birth process, providing real-world experience beyond videos.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and asks them to recall what they learned about animal reproduction. The teacher then introduces the topic “Practical on Parturition” by explaining its importance in animal husbandry.
Pupils’ Activity: Pupils respond to the teacher’s questions and listen attentively.
Learning Point: Pupils are prepared for the new lesson and understand its relevance.

Step 2: Definition of Parturition

Time: 7 minutes
Teaching Skill: Explanation/Definition
Teacher’s Activity: The teacher defines parturition, explaining it as the process of giving birth in animals. The teacher ensures pupils understand it marks the end of pregnancy.
Pupils’ Activity: Pupils listen, take notes, and ask questions for clarification.
Learning Point: Pupils understand the meaning of parturition.

Step 3: Identification of Approaching Parturition Signs

Time: 10 minutes
Teaching Skill: Demonstration/Observation
Teacher’s Activity: The teacher uses charts and discusses the various physical and behavioural signs that indicate an animal is about to give birth. The teacher encourages pupils to describe what they see on the charts.
Pupils’ Activity: Pupils observe the charts, identify the signs, and discuss their observations with the teacher and peers.
Learning Point: Pupils can identify key signs of approaching parturition.

Step 4: Observation of Parturition Process (Video)

Time: 10 minutes
Teaching Skill: Visual Aid/Discussion
Teacher’s Activity: The teacher shows short video clips of parturition in different farm animals (e.g., cow, goat, pig). The teacher pauses the video to highlight the stages of birth and points out the signs discussed earlier.
Pupils’ Activity: Pupils watch the videos carefully, observe the birth process, and ask questions.
Learning Point: Pupils gain visual understanding of the parturition process.

Step 5: Discussion on Farm Visit Preparation and Importance

Time: 5 minutes
Teaching Skill: Discussion/Application
Teacher’s Activity: The teacher discusses how the knowledge gained from videos and charts would be applied during an actual farm visit to witness a birth. The teacher explains the importance of careful observation and preparation for such a practical experience.
Pupils’ Activity: Pupils contribute to the discussion, asking about what to look for and how to behave during a farm visit.
Learning Point: Pupils understand the practical application of their learning and the value of real-world observation.

Step 6: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define parturition.
Mention three signs that indicate an animal is about to give birth.
Describe one key event that happens during the delivery stage of parturition.
Why is it important for a farmer to monitor animals during the parturition period?

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 7: Conclusion

Time: 3 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the key points of the lesson, reiterating the definition of parturition, its signs, and the importance of observation. The teacher assigns homework: “List five farm animals and their gestation periods.”
Pupils’ Activity: Pupils listen to the summary and copy the homework.
Learning Point: The lesson is reinforced, and pupils have follow-up activities.

Lesson Keywords

Parturition – The process of giving birth in animals.
Gestation – The period of development of an embryo or foetus in the mother’s uterus.
Udder – The mammary gland of female livestock, especially cows, goats, and sheep.
Vulva – The external female genitalia of mammals.
Colostrum – The first form of milk produced by the mammary glands of mammals immediately following delivery of the newborn.

Differentiation

For pupils who grasp concepts quickly, the teacher can encourage them to research specific challenges or complications during parturition and how they are managed. For those needing more support, the teacher can provide simplified charts or extra time for reviewing video segments, focusing on one sign or stage at a time.

Note for teachers using this lesson plan

Ensure that the video clips of parturition are appropriate for the age group and focus on the educational aspects rather than graphic details. If a farm visit is planned as a follow-up, ensure all safety protocols and permissions are in place. Encourage pupils to take notes during video observations and discussions to reinforce learning.
