Cultures: The Farms of the Lab

Step into a microbiology lab, and you might feel like you’ve wandered onto a tiny, futuristic farm. But instead of cows and cornfields, you’ll find stacks of clear dishes filled with jelly-like soil and colonies of colorful “crops.” Welcome to the world of microbial cultures, where scientists become the world’s smallest-scale farmers, cultivating invisible life into lush, visible harvests. Just as a farmer tends the land to grow food, a microbiologist cultivates bacteria, fungi, and other microbes on nutrient-rich media. These miniature farms don’t just look cool—they are the heartbeat of diagnostic medicine, research, and biotechnology. Let’s take a tour behind the barn doors of the lab. The Fields: Agar Plates and Broth Pastures Every farm needs soil. In the microbe world, our “fields” come in two main forms: solid and liquid. - Agar plates are the lab’s equivalent of neatly plowed plots. Agar, a seaweed-derived gelatin, creates a firm surface where microbes can put down roots—well, ...

complete guide to chicken feed formulation

 Complete Guide on Poultry Feed Formulation and Calculations Poor quality feeds lead to a slow growth in chickens, low egg production, diseases or even death.  Making poultry feeds  on the farm is one of the best ways to maintain quality and cut the cost of production. The common ingredients are whole maize, maize germ, cotton seed cake, soya beans, sunflower or fish meal (omena). In addition, farmers need to add several feed additives (micronutrients, minerals and vitamins) to make ensure their chicken have a balanced feed that meets their daily nutrient requirements. Material is available cheaply, especially after the harvesting season. Depending on the cost of raw material, farmers who make their own feeds at home save between 30 to 50 per cent for every 70kg bag of chicken feed, depending on the source of their raw materials. Due to government regulation, major feed companies have reduced the standard quantity of feed from 70kg to 50kg per bag, but the price of f...

hatching chicks

how to hatch chicks Hatching Chicks If you already have chickens (or know someone who does), there’s always the option of hatching your own chicks. Of course, you’ll also need a rooster to get fertile eggs. Check your zoning regulations; some places allow hens, but not roosters. Hens will lay perfectly well without one. You’ll also need a broody hen. Broodiness—the instinct to sit on eggs until they hatch—has been bred out of a lot of chickens, but we always had one or two who would begin to sit tight on the nest and peck if we tried to remove their eggs. Bantams are famously broody, and a bantam hen will hatch other hens’ eggs. You can hatch replacement chicks yourself with a home incubator. Eggs take 21 days to hatch. An incubator must be monitored diligently; chicks left too long after hatching will die of dehydration or picking. On the whole, we found it best to leave hatching to the hen. (Did you know that there are best times for setting eggs und...

Raising Chickens 101: How to Raise Baby Chickens Tips for Raising Young Chickens in Your Backyard Want to learn how to raise chicks? Here’s a beginner’s guide to bringing up baby, from purchasing baby chickens to keeping a happy coop. Where to Get Baby Chickens There are a number of ways to go about getting chickens! Most often, chicks can be bought locally in the spring, from farm supply stores or small farms themselves. These days, you can even go online to order chicks and get them shipped to your door (or local post office). Then there’s always the “ask a friend with chickens to hatch some for you” approach. Purchasing Chicks You can purchase chickens at several stages of development—it all depends on how long you’re willing to wait for eggs. Day-old chicks  are available from hatcheries. Most farm suppliers do one or two chick orders a year, so you can get your chickens where you plan to get your feed. They’re usually under $3 each. You’ll have to...

TECNO Camon 15 and Camon 15 PRO launched with 48MP cameras

Image
TECNO’s first phone with a pop-up camera, and first phone running Android 10 out of the box have officially been launched. They continue with TECNO’s audacious trends of bringing exciting specifications to the budget segments. The new phones all pack 48MP main shooters at the back, and all come with huge batteries. I don’t know why TECNO is going with Camon 15. The last we’ve seen from the Camon series is the  Camon 12 series . Why the company is jumping straight to Camon 15 is weird. Maybe there will also be a Camon 13, and 14 somewhere in between, but who knows. Back in January, I had a post saying  TECNO’s first phones with a pop-up camera  would be launching soon. We can also expect an Infinix phone with the same specs to also be announced soon. These will be the devices for the March-April smartphone launch cycle in the Kenyan market. Huawei, Samsung, TECNO, and Infinix will all be launching new devices. The two new phones are however only currently available in...
