Like I said before in this thread, I finally found duckweed. But I don't have enough space to build a big earthen pond where I'll plant them. so I'm presently keeping them alive in a small basin until I can get sufficient space. I've also harvested some and dry them. I fed some to my broilers.

   
   

Biogas Production: Avoid Failure by Using the Correct Carbon-Nitrogen Ratio

   

·     is mainly a problem in Gram-negative bacteria: E. coli, Salmonella
·        resistant strains can be introduced by one-day old chicks through the hatchery. So resistance is possible in farms where no drugs have been used
·        routine preventive treatments increase resistance
·        low concentrations (often in preventive treatments) increase resistance
·        some drugs easily create resistance: streptomycin
·        some drugs create multi-resistance. Multi-resistance is the combined resistance to different groups of drugs (e.g. neomycin)
·        in a healthy environment, where no antibiotics/chemotherapeutics are used, the resistance disappears rather rapidly.

Unlike humans, when pigs are born, they enter the world without any immunity against foreign elements like disease-causing pathogens. Their chance for survival relies heavily on getting enough colostrom—a milk-like substance produced by mammals after giving birth.

Newborns that fail to nurse and receive colostrum from the sow within the first 24 hours usually die. That's because piglets are born with limited energy stores, and colostrum also provides the energy they need to stay alive.

For the swine industry, preweaning mortality has long been a major problem, costing an estimated $1.6 billion each year. Now, a new tool may help give these at-risk animals a second chance.

To improve neonatal piglet survival, Agricultural Research Service physiologists Jeffrey Vallet, Jeremy Miles, and Lea Rempel at the U.S. Meat Animal Research Center (USMARC) in Clay Center, Nebraska, have developed a measuring technique referred to as the "immunocrit" that can determine whether neonatal piglets have received adequate colostrum from the sow.
Colostrum contains immunoglobulins, which are antibodies made by the sow's immune system to protect against bacteria, viruses, and other foreign substances. Humans receive these antibodies in their mother's womb, but pigs and other livestock rely on passive transfer through nursing after birth, says Vallet, research leader of USMARC's Reproduction Unit. Thus, piglets are born with no immunoglobulin, and piglet serum immunoglobulin reflects their colostrum intake.

"Colostrum gives piglets their first antibodies so that they can have some immunological protection during the first couple of days of life," Miles says. "If they don't suckle, they don't have any immunoglobulins." 

The Immunocrit at Work
The immunocrit, which measures newborn piglet serum immunoglobulin, is simple, inexpensive, rapid, and accurate. It is similar to the hematocrit, used for years by doctors to measure the volume of blood cells and determine whether a patient is anemic, Vallet says.

Blood samples are taken from piglets on day one after birth, mixed with ammonia sulfate to precipitate immunoglobulin, put into a microcapillary tube, and spun so the precipitated immunoglobulin settles to the bottom. The volume of the precipitated immunoglobulin is then measured and divided by the total volume in the tube.
 
"We can go through a litter of piglets and take blood samples quickly and easily, and the assay itself is very simple to use," Vallet says.
 
Scientists have demonstrated that immunocrit measurements are predictive of piglets' mortality and nursing ability and that the average immunocrit of piglets in a litter reflects the sow's colostrum production capability. Because the test is so rapid, it is possible to identify compromised piglets and take steps to rescue them, Vallet says. 
 
Help for the Smallest
The immunocrit is good at identifying piglets within a litter that haven't eaten at all or haven't had the opportunity to nurse, Miles says. In one experiment, scientists used the immunocrit to assess colostrum intake in a group of piglets—the smallest from each litter—and then measured the contents of each piglet's stomach. They found that some piglets' stomachs were nearly empty. Those same piglets had an immunocrit measurement of nearly zero, validating that the immunocrit accurately detects piglets that receive no colostrum within a 24-hour period.
 
Immunocrit results correlated well with results from a more complicated and expensive traditional method—protein A sepharose combined with electrophoresis—in detecting piglets that had not nursed at all.
 
In another study, using more than 2,000 piglets, researchers found that the immunocrit could predict preweaning survival. They also noted a connection between immunocrit measurements and piglet weight: Heavier piglets were more likely to survive the challenge of not getting colostrum within the critical time frame. 
 
Enhancing Management Practices
The immunocrit can be used to test management practices, such as split suckling, and other strategies used by swine producers to help prevent colostrum deficiency, Vallet says.
 
Split suckling is a labor-intensive method that involves marking the first-born group of piglets, putting them aside, and then allowing the last piglets born uninhibited access to the sow. The practice is designed to improve access to colostrum for later-born piglets, because studies have shown that there is some influence of birth order on colostrum intake.
 
"The immunocrit can be performed 24 hours after the split suckling procedure to find out if progress is being made in improving colostrum in different piglets," Vallet says. "Producers can also use the immunocrit as a monitoring device for day-one piglet care. For example, they can randomly select piglets and benchmark how those piglets are doing."
 
The new technique isn't just for pigs. It could also fit well into management practices of cattle producers. The immunocrit was successfully used to monitor colostrum intake of 96 calves 24 hours after birth. 
 
Taking a Genetic Approach
"Another strategy is to use genomics to modify the colostrum-piglet-mother interaction during that first 24-hour window," Vallet says. "We should be able to use the immunocrit to get some idea of the sow's ability to produce colostrum and then genetically select for colostrum production."
 
Preliminary research conducted by Gary Rohrer, a geneticist at USMARC, suggests that individual immunocrit values are heritable, presumably because nursing ability is heritable. From analyses of piglets and their mothers, Rohrer found the most significant portion of the variation—50 percent—is accounted for by the piglet's genetics. The mother is responsible for 20 percent of the variation.
 
Immunocrit data collected from 500 litters—about 5,000 piglets—provide a valid sample for genomic research, Vallet says. Data from each individual piglet is an indicator of its nursing ability, but the average across all piglets gives some indication of the sow's colostrum-production ability.
 
"When it comes to genetic associations, the more numbers, the better," Rohrer says. "Not only do we have a much higher heritability for the actual piglet's ability or potential, we also have a lot more records."
 
Rohrer plans to group DNA from piglets with very high immunocrit values and compare it with DNA collected from piglets with very low values.
 
"We can efficiently genotype those pools of DNA, estimate frequencies, and hopefully identify regions of the genome that are affecting the pig's ability to acquire and absorb colostrum," he says.
 
If successful, researchers would be able to recommend genetic markers that allow pork producers to identify and breed sows that ably produce colostrum and piglets with improved neonatal nursing abilities— an outcome that would help reduce the odds of preweaning mortality.- By Sandra Avant, ARS.

Abstract

On average, 1 liter of pure human urine contains about 7 gm nitrogen, 1 gm Phosphorous, 2 gm potassium, 1 gm sulphur, 80 mg magnesium and 200 mg calcium. As a result, it can be a cheap source of organic nutrients for plants. Urine from animals (cattle, rabbit etc) can also be used.
 
How to Collect Urine: Ecological sanitation (Eco-san) toilets can be used to collect human urine since they have separate hole for urine diversion and feaces. The urine is channeled to the collection vessels through a polythene pipe. Jerry can or plastic tanks with 15-25 liters capacity can be used as collection vessels for household. If eco-san toilets are not available, you can improvise a way to collect urine.
On large scale, urine can be collected from public places such as hotels, bus
parks etc.
Storage: The urine is stored for at least 1 month in airtight cans to kill enteric microorganisms prior to using in plants. Air must not be allowed to get into the storage container because it will react with the urine and lead to nitrogen loss in the form of ammonia. Stir the urine from time to time to prevent phosphorus precipitation. Storing for more than 100 days ensures that all enteric microbes are killed.
How to Use: It can be diluted and used to fertilize crops or in an undiluted form, it can be used as a soil drench for fruit trees. To reduce nitrogen loss after applying urine fertilizer, work it into the soil and apply when the temperature is low (morning or evening).
 
The amount to apply will depend on soil fertility, other source of nutrients used and requirement of the plant. You’ll get better results when urine fertilizer is applied in the early growth stage of the crop. This is because nitrogen is essential for leaves growth.
 
To fertilize vegetables with urine fertilizer, dilute it with water in a urine:water ratio of 1:6. Use this to fertilize the soil around the roots. Application interval is every 15 days or thereabout.
As a foliar fertilizer (i.e. fertilizer spread on the leaves), the dilution rate should be 1:10. This is mainly used for young plants. Spray both sides of the leaves. Application interval is every 15 days or thereabout. Note that as foliar fertilizer, the urine must be diluted to avoid burning the leaves.
 
For fruit trees, you can apply to the root zone without diluting. Application interval is 2-3 times per year at 15-20 liters per application.
Urine fertilizer can be applied to all crops, but it is mainly used in vegetables and fruit trees whose edible parts do not touched the soil.
 
Other Uses: It can also be mixed with compost and used a lime substitute (to correct acidic soil) since urine increases soil pH.
Precaution: Never apply urine directly on the parts of the plants harvested and it should be stopped at least 1 month before harvesting to avoid any possible risk of crop contamination with germs. Another thing to prepare for is smell. You may fine it offensive.

Cow’s milk is used to suppress viral and Fungal diseases in cucumber, tomato, pepper and other crops. It does this by increasing the pH of leaf surface (6.2-6.8), thus establishing a protective barrier and the crop develops systemic resistance to diseases. Milk protein (casein) inactivates the virus protein (capsid protein) in plants.
 
This technique is being used by many organic vegetable growers.
 
How to Apply: Mix 1 part cow milk with 8 part water or 15g dry milk per liter water. Spray on your plants at 7 days interval. You may also spray once in 15 days before disease appearance and at 7 days interval for reducing the spread of virus. Spray both sides of the leaves (top and bottom) and spray when the sun is not shining (morning or evening) - NO! A source said it works better in the presence of sunlight! . Note that application at higher concentration MAY not be economical and you should practice this only if cow milk is readily available and cheap. You can also use whey if you have access to it and it is cheaper.
 
This spray has been reported to be effective in controlling powdery mildew - a fungal disease prevalent during dry seasons.

Quote:Turning now to large scale assembly in quick succession, it has already been mentioned that very few plants are in operation today. This was not the case even two years ago. In the late 1990s medium to large processing facilities were operating, many as starch manufacturers.
 
However, many of these industries closed down because they were working at low and seasonal capacities. Peak Products Nigeria Limited is an example of a company that was able to adjust under adverse circumstances and thus remain in operation. Its story is worth describing here in some detail. 

Peak Products Nigeria Limited began cassava processing in 1998 with the sun drying of cassava flour. The flour was sold to bakeries and confectionaries through Ogun State Agricultural Development Programme (Agro Processing Unit). However, some processors began contaminated fermented cassava flour with unfermented cassava and by 1999-2000 the flour bakeries and confectionaries stopped asking for and using cassava flour. This forced Peak to shift to the production of sun dried cassava starch.  With growing demand for cassava starch, Peak upgraded from sun drying to the use of a mechanical dryer. Using a flash dryer, production capacity achieved 3-5 tonnes per day, 72 000 tonnes per year with a daily input of 25-30 tonnes of wet starch.
 
Flash drying however requires a wet milling component. Faced with environmental problems, the company was forced to stop wet milling and instead obtained wet cake from rural women. At present Peak is currently under utilized in its production of cassava starch because it has diversified production into the fabrication of flash dryers.
 
Existing buyers of Peak’s flash dryers are predominantly chemical companies from the Sango-Lagos Axis and a few beverages and food industries. Prospective buyers include Nigerian Distilleries in Ota who want 150 tonnes of cassava flour per day for ethanol production. DeUnited Nig Ltd., is looking to produce 60 000 tonne of cassava flour per month for noodles (Ndomie Noodles). Oil companies are interested in producing cassava starch for drilling muds11. Textile industries, although not currently using local cassava starch negotiations are currently underway between the Government, cassava processors and the textile industry. Finally, paper mills such as Iwopin Paper Mill in Ogun State and Okui Ibokwe Paper Mill in Akwa Ibom State may also patronize cassava starch in the near future12
 
Although no one can know the likelihood that these prospective buyers will actually purchase, their efforts to search out information on cassava processing fabrication offers hope. Their slowness to invest however may be a symptom of uncertainty regarding future government policy directions, uncertainty in being able to produce competitively and uncertainty in their ability to source cassava roots. As illustrated in the Peak example, cassava processing is vulnerable to many conditions – market vagaries, trade policy, product substitution, and adverse environmental impacts, to name a few.
 
The ability (or inability) to source a reliable stream of good quality cassava roots is also a real concern for cassava processors. Problems relating to sourcing cassava roots are a serious deterrent for industrialists as described in the following example of the Mosaconi Cassava Factory in Kogi. The Mosaconi Cassava factory was a large operation that utilized raw cassava from farmers for the production of packaged gari and laundry starch for local markets. It began operations in 1993 but closed in 1999. Before the establishment of the factory, the community used cheap cassava for the production of local staple foods like lafun and gari. When the company began, it patronized all cassava growers in the state and bought most of the cassava from their farms. This resulted in a scarcity of cassava and a higher selling price for smaller local processors. As local cassava prices rose, public complaint by the local people surfaced that the presence of the factory was increasing the price of lafun. This resulted in host of problems such as pilfering, administration fraud, and use of poor land, lack of adequate accurate information and vandalism of factory equipment. The factory suffered as a result and faced a shortage of cassava for its operation. Since the factory had no farm of its own, it tried to solicit cassava growers to supply cassava into the factory through radio and television jingles. This only encouraged cassava growers to truncate the maturity of planted cassava, selling cassava of less than eight months old. After many unsuccessful attempts at troubleshooting, the owner was forced to close down the company. Clearly if cassava processing is to mature in Nigeria these types of deterrents must be resolved.

This is my backyard Turkey farming, they are hybrid and i bought them at 8weeks old.    

Good morning house. I am new here.

I am here to exchange views with fellow snail farmers. I won't bore you with lots of write ups. I will give you Just the needful.

Hi guys,

I am new here and I think this forum is fabulous! I would appreciate information on the set up of a small scale abattoir...and beef processing. Any ideas, information or materials? Please help out!!

My strong point is business planning, and I would be glad to share!!

Hello farmers, please were can I get alfalfa and elephant grass in the north for my rabbits and what are their names in Hausa please?

Gud evening all. Pls How long can egg store without refrigeration?

I’m planning to start layers farming. Pls what size is needed for 1000 birds?

Pls like how much will it cost someone to something like 100 layers until they start laying eggs?

How much methane can one get from cow manure? Also, how much is needed to cook food?

To save housing cost.

Hello evryone. Should day old chicks be brooded on newspapers, sawdust or wood shavings? I get conflicting info when I searched google.

Below are some valuable info I got from some guys in nairaland and I wish to share them with you.

1. To succeed target hotels, eateries and cold rooms, or start your own outlet. Selling live birds is only sustainable under small scale and seasonal.

2. Rear 1000-10,000 birds per batch to make reasonable profit. Harvest should be at least weekly.

3. Feed adlibitum so that they grow fast. But introducing few hours of no feed will increase feed efficiency. A well-managed flock will weigh between 1.8-2.4kg in 6-7wks and upon dressing, will weigh between 1.4-1.8kg. this is the standard weight for most eateries.

4. Some companies that buy live birds pay between N410-600/kg live weight. Eateries and some cold rooms pay N600-820/bird dressed weight.

5. Profit Expectation: N150-250/bird.

6. Possible Needs: Cold room, defeathering machine.

Thanks.
