Coconut Water Aids Artificial Insemination of Pigs

Coconut Water Aids Artificial Insemination of Pigs
Jul 01, 2022

Using nutrient-rich coconut water to artificially inseminate female pigs could improve breeding and meat quality, a project carried out in Uganda has found.

Uganda has the highest demand for pork in East Africa at 3.4 kilograms per capita per year and a population of 3.6 million pigs providing livelihoods to over 1.1 million households, according to the International Livestock Research Institute.

Researchers conceived the community action project after realizing that most smallholder pig farmers keep poor breeds resulting in low growth rates, few piglets produced, and poor quality pork with little lean meat and high-fat content.

"Artificial insemination facilitates the collection of boar semen from superior boars to improve the genotypes, and subsequently higher productivity is achieved," said Elly Ndyomugyenyi, the project's lead researcher and senior lecturer at the department of animal production at Uganda's Gulu University.

Farmers take fresh  water from five-month-old fruit known to be rich in nutrients such as sodium and potassium, he added. The water is used to aid insertion and delivery of the semen into the female pig's reproductive canal.

"High concentration of sodium and potassium in the green coconuts are factors which help in sperm motility and longevity," Ndyomugyenyi explained. "Coconut fruits are readily available in the local markets. They are sold like other local fruits."

Extraction is done by opening the fruit with a sanitized blade, after which the water is poured into a clean beaker before it is transferred using a cotton cloth.

The project, which is an initiative of Uganda-based Regional Universities Forum for Capacity Building in Agriculture (RUFORUM), started in 2017 and has engaged nearly 1,000 smallholders in Uganda, Ndyomugyenyi said.

Farmers under the project have been trained in better husbandry and are now organized into a pig farmers' association—something that never previously existed in the area—added Anthony Egeru, who heads the community project at RUFORUM.

Natural mating using boar (male pigs) comes with a myriad of risks including  and inbreeding that leads to poor quality offspring, he explained.

It exposes pigs to the deadly African swine fever virus because of the movement of boars from one place to another. In many instances, a whole village can use one or two boars to mate sow, increasing the risk of transmitting diseases.

Joab Malanda, a pig production expert at the department of animal science at Egerton University, Kenya, said that, as well as aiding the insemination process, coconut water helps increase the number of viable live spermatozoa cells and extends their life.

"Outside a boar's body, the spermatozoa will live for about four hours, after which they start to die due to starvation and , but when it is added to coconut water, they will live for up to 96 hours, allowing insemination at the appropriate time," he toldSciDev.Net.
