    Protocooperation refers to a type of symbiotic relationship in which two organisms interact in a way that benefits both parties, but is not essential for their survival.

    In the context of yoghurt manufacturing, protocooperation occurs between the different strains of bacteria used in the fermentation process.

    Yoghurt culture bacteria, such as Lactobacillus bulgaricus and Streptococcus thermophilus, exhibit protocooperation by working together to ferment the milk sugars into lactic acid.

    While each strain is capable of producing some lactic acid on its own, the presence of both strains enhances the fermentation process and results in a more rapid and efficient production of yoghurt.

    The benefits of protocooperation in yoghurt manufacturing include faster acidification of the milk, which helps prevent the growth of harmful bacteria and ensures the safety and quality of the final product.

    Additionally, the combined action of the bacteria leads to the production of unique flavours and textures in the yoghurt, contributing to its overall desirability for consumers.

    Steric hindrance refers to the repulsion or interference that occurs when bulky groups attached to molecules come into close proximity with each other.

    This interference can restrict the movement or reactions of the molecules, affecting their overall behaviour.

    An analogy for steric hindrance could be like trying to fit a large piece of furniture through a narrow doorway.

    The bulkiness of the furniture can make it difficult to manoeuvre through the door, just as bulky groups on molecules can make it challenging for them to interact or react effectively.

    Steric hindrance is significant in chemistry because it can impact the shape and reactivity of molecules, affecting various chemical processes such as molecular interactions, reactions, and biological activities.

    Grass tetany, also known as grass staggers or hypomagnesemia, is a common metabolic disorder that affects ruminant animals such as cattle and sheep. It is primarily caused by a deficiency of magnesium in the animal’s bloodstream, which can lead to severe health complications if not addressed promptly.

    Understanding Grass Tetany

    Causes and Risk Factors

    Grass tetany typically occurs when there is an imbalance of minerals in the animal’s diet, particularly a deficiency of magnesium. Factors that contribute to the development of grass tetany include:
    1. Low Magnesium Levels in Forage: Grazing on pastures with low magnesium content can lead to a lack of magnesium intake, making animals more susceptible to grass tetany.
    2. High Potassium and Nitrogen Levels: Pastures with excessive potassium and nitrogen can interfere with the absorption and utilization of magnesium in the animal’s body.
    3. Rapid Grass Growth: During periods of rapid grass growth, magnesium availability in the plants decreases, further exacerbating the risk of grass tetany.
    4. Physiological Condition of the Animal: Sick and old or younger animals may be more susceptible to grass tetany due to compromised immunity.

    Symptoms and Diagnosis

    Identifying the symptoms of grass tetany is crucial for prompt treatment. Common signs include:
    1. Muscular Twitching: Animals affected by grass tetany may exhibit muscular twitching, particularly around the face, ears, and flanks.
    2. Staggering Gait: Infected animals may have an unsteady gait, struggle to maintain balance, and exhibit difficulty in moving.
    3. Nervousness and Agitation: Grass tetany can cause animals to become restless, agitated, and display signs of discomfort.
    4. Reduced Appetite: Affected animals may show a decreased interest in grazing or consuming feed.
    5. Convulsions and Collapse: In severe cases, grass tetany can progress to convulsions and even result in the animal collapsing.
    If you suspect grass tetany in your livestock, it is vital to seek veterinary assistance for a proper diagnosis. Veterinarians often conduct blood tests to measure the magnesium levels in the animal’s bloodstream and confirm the presence of grass tetany.

    Resolving and Preventing Grass Tetany

    Supplementation and Balanced Diet

    One of the primary methods to resolve and prevent grass tetany is through magnesium supplementation and maintaining a balanced diet. This involves:
    1. Magnesium Supplementation: Providing magnesium supplements, such as mineral blocks or oral drenches, can help replenish the animal’s magnesium levels. It is important to consult with a veterinarian to determine the appropriate dosage for your livestock.
    2. Balanced Forage: Ensuring that the animals have access to high-quality forage with adequate magnesium content is crucial. Regular soil testing and appropriate fertilization can help maintain optimal mineral levels in the pasture.
    3. Mineral Mixtures: Using mineral mixtures specifically designed for grass tetany prevention can be beneficial. These mixtures often contain a balanced combination of magnesium, calcium, and other essential minerals.

    Pasture Management

    Proper pasture management practices play a significant role in minimizing the risk of grass tetany. Consider the following strategies:
    1. Grazing Management: Implement rotational grazing practices to allow forage regrowth and reduce the intake of magnesium-deficient plants. This helps ensure a more balanced diet for the animals.
    2. Supplemental Feeding: Providing additional feed, such as magnesium-rich hay or silage, during periods when the risk of grass tetany is high, can help mitigate the deficiency. Cows need at least 2g/kg DMI per day.
    3. Timing of Grazing: Avoid grazing animals on fresh/ early season pastures that are still deficient of magnesium.
    4. Apply Magnesium to Pasture: Apply magnesium oxide to the pasture at the rate of 30kg/ha every 21 days during the risk period. You can also spray pasture with magnesium sulphate every 2 weeks (2% magnesium sulphate in 1000L per hectare = 20kg/h).
    5. Long-term Remedy: Apply dolomite (contains some magnesium) or lime to correct the acidity of the soil. Plant clover crops and apply phosphate fertilizers. You should also limit application of nitrogen and potash fertilizers until the soil acidity is corrected or the clovers established.

    Monitoring and Regular Veterinary Care

    To effectively manage and prevent grass tetany, it is essential to monitor the condition of your livestock and maintain regular veterinary care. Consider the following:
    1. Health Checks: Regularly assess the overall health and condition of your animals. Promptly identify any signs of grass tetany and seek veterinary assistance when necessary.
    2. Vaccinations and Deworming: Follow recommended vaccination schedules and deworming protocols to minimize additional stressors on the animals’ immune systems.
    3. Record Keeping: Maintain accurate records of your livestock’s health, diet, and mineral supplementation. This helps track their progress and enables better management strategies.
    By ensuring adequate magnesium supplementation, maintaining a balanced diet, implementing pasture management strategies, and seeking regular veterinary care, you can minimize the risk of grass tetany and promote the overall health and well-being of your animals.

    Registered dairy cattle have a higher market value than unregistered ones. This is because their pedigree can be verified by the available records, which gives their buyers more confidence during acquisition.
     
    Some of the benefits of registering dairy cattle include:
    1. Higher market value for the registered livestock
    2. Ease of tracing ancestry of animals
    3. A farmer can breed their stock up to pedigree level without spending a fortune
    4. Farmers with registered bulls can be contracted to contribute to the National Breeding Program (i.e. Kenya Agricultural Genetic Resource Centre – KAGRC).
    5. Farmers can also participate in contests and shows (e.g. Agricultural Societies of Kenya – ASK show), which gives them a larger platform to market their stock at a premium
    6. Registration records are important for the conservation of the national biodiversity assets.
    7. Farmers are better informed when making decisions on breeding, feeding, culling, and claiming insurance.
    The registration entails a number of documentations to keep track of various critical dimensions of the animal of interest. For instance, the registered animal has records to show their milk production data (including quantity and quality of the milk), certification of lactation, and certification of lifetime productivity.
     
    With these certifications, the farmer can avail the records to the local livestock breeding centre to be incorporated into the National Breeding Program.
     
    They also get to enjoy professional extension service delivery to ensure proper livestock management at the farm.
     
    Procedure for getting your cow registered in the Kenya Stud Book
    1. Make sure your animals are properly marked for easy identification. Read the following rules and guidelines to have a better grasp of what is expected of you during the process.

    Why do milk processors buy raw milk by weight and sell processed milk by volume?

    There is a commercial incentive to this principle, and you will shortly see why this is the industry standard way of doing things. The average density of milk is 1.032kg/l. Because of this, the processor is in in effect getting more volume of milk per weight paid for.
    To get the volume of milk per Kg, you can do cross-multiplication and you’ll end up with 0.97 litres of milk per unit. This means that the processor is getting 0.03 extra litres of milk per litre of milk bought “without paying for it”.
    This may seem negligible when you look at it from the face value, but things begin to add up fast when you consider the volumes serious processors handle per day. For instance, let’s say a particular processor procures 800,000 Kgs of milk per day from farmers. This means the processor is getting an edge of (800000*0.03 = 24,000 litres of milk per day).
    Now multiply that volume by the prevailing price of milk per litre and see the magic. Even if you give the process a 90% efficiency (which is unacceptable in the dairy industry), the figures are still looking up.
     
    Do processors make losses?
    Yes, they do. But they have measures in place to recover the losses. This is just one of them.
