Forage Conservation And Utilization

Visão Geral

Grass grows fastest exactly when livestock need it least. Through the rains, pasture around Kaduna, Makurdi or Jos grows thick and lush, far more than a herd can eat in a day, while by January the same fields are bare and brown and animals lose condition fast. Forage conservation is the answer to that mismatch: cutting the wet season's surplus grass and legume at their best and locking that quality in, as hay or silage, so it is still good feed months later when the dry season bites.

The two methods that do this work in almost opposite ways. Hay making dries forage until it is too dry for anything to spoil it. Silage making seals moist forage away from air until fermentation itself keeps it from spoiling. This lesson takes you through both processes step by step, shows you how to tell one from the other by moisture content alone, and covers how conserved forage is actually fed out and checked for quality once the harmattan arrives.

Objetivos

Define forage conservation
Explain the methods of forage conservation
Distinguish between hay making and silage making
Explain the methods of forage utilisation
State the importance of forage conservation to livestock production

Nota de Aula

A herder near Sokoto lets the wet season surplus on his range stand uncut; by November his range is bare and his cattle lose weight daily. A neighbouring cooperative baled hay from the same rangeland back in September, and through the harmattan their cattle are fed from that store and hold condition. Neither controls the weather. Only one of them conserved the grass his land already gave him for free.

Resposta

a) i. To obtain specimen A (dry groundnut haulm), you can follow the steps below:

Harvest the groundnut plant when the pods are fully mature and the leaves have dried up.
Cut the plant near the base, leaving a few inches of the stem.
Hang the cut plants in a well-ventilated area to allow the leaves to dry completely.
Once fully dry, remove the leaves from the stem and store in a dry place until ready for use.

ii. Three benefits that farm animals could derive from feeding on specimen A (dry groundnut haulm) include:

High protein content which can improve animal growth and production.
Rich in fiber which can help improve digestive health and prevent digestive disorders.
Good source of energy which can help improve animal performance and overall health.

b) i. Two methods that could be used to propagate specimen B (Guinea grass) are:

Vegetative Propagation - This involves taking cuttings from existing plants and planting them in soil to grow new plants.
Seed Propagation - This involves sowing seeds in soil to grow new plants.

ii. To preserve specimen B (Guinea grass), you can follow the steps below:

Cut the grass into small pieces and dry it in a well-ventilated area.
Once fully dry, store the grass in a dry, cool place, such as a barn or shed.
To protect it from insects and other pests, you can wrap the grass in plastic or keep it in an airtight container.

c) Specimen C (Kitchen knife) can be used in animal production in the following ways:

For slaughtering animals - A sharp knife is used to humanely slaughter animals for meat production.
For castrating animals - A knife is used to castrate male animals to prevent unwanted breeding.
For dehorning animals - A knife is used to remove the horns of animals, such as cattle, to prevent injuries to other animals and humans.
For tail docking - A knife is used to shorten the tails of animals, such as pigs, to prevent injury and improve hygiene.
