14-Feb-2023: Black Soldier Fly and its utilization in Poultry industry

Black soldier flies (BSF), scientifically known as Hermetia illucens, are becoming increasingly popular in the poultry industry. These flies are not only environmentally friendly but also provide a sustainable alternative to traditional protein sources. In India, the utilization of black soldier fly larvae (BSFL) is being explored as a sustainable and cost-effective source of protein for poultry feed.

Black Soldier Fly

Black Soldier flies have a distinctive black color and are approximately 16-22mm in length. They have a short lifespan of only 5-8 days and do not have functional mouthparts. The lifecycle of black soldier flies consists of four stages: egg, larva, pupa, and adult. The larvae of these flies are voracious eaters and can consume organic waste such as food scraps, animal manure, and agricultural byproducts. As a result, the larvae can be used to convert these wastes into a valuable protein source for poultry. They do not consume food during their adult stage and are not vectors for disease.

Benefits of Black Soldier Fly

BSF have numerous benefits that make them a valuable resource in the poultry industry. They provide an alternative to costly and often unsustainable protein sources such as fishmeal and soybean meal. They are also an environmentally friendly source of protein. Unlike traditional protein sources such as soy and fishmeal, which require large amounts of land and water, BSF require minimal resources to thrive. BSF larvae can be reared on various organic waste materials such as food scraps, animal manure, and agricultural by-products, making them an excellent way to repurpose waste and reduce waste disposal costs. Also, it can lead to a decrease in greenhouse gas emissions and other negative environmental impacts.

Secondly, BSF larvae are highly nutritious and can be a valuable protein source for poultry. The larvae are rich in amino acids, lipids, and minerals, making them an ideal supplement for poultry feed. BSF larvae can also help improve the digestibility of other feed ingredients, leading to better feed conversion and reduced feed costs. This makes them an attractive option for poultry farmers who are looking to improve the quality of their feed and promote the growth and development of their birds. Furthermore, BSFL are a rich source of calcium, which is essential for eggshell formation in laying hens.

Utilization of Black Soldier Fly in the Poultry Industry

The use of BSFL in poultry farming is still in its infancy in India, but it has already shown promising results. A study conducted by the Indian Institute of Technology (IIT) Delhi found that the inclusion of BSFL in the diet of broiler chickens improved their growth rate and feed conversion efficiency. The study also reported a decrease in the cost of feed by up to 50% when BSFL was used as a protein source.

The potential benefits of using BSFL in the poultry industry are not limited to just broiler chickens. In fact, BSFL can be used in the diet of all types of poultry, including layers, turkeys, and ducks. Furthermore, the use of BSFL can also have positive impacts on the environment by reducing the amount of organic waste that ends up in landfills.

The use of BSFL can improve the quality of feed, reduce the cost of production, and contribute to sustainable development. As the demand for sustainable protein sources continues to grow, it is likely that BSFL will play an increasingly important role in the poultry industry.

28-Jan-2023: Punjab State government airlifts 25 lakh doses of goat pox vaccine

Punjab State government has airlifted 25 lakh doses of goat pox vaccine to carry out a free vaccination campaign for early prevention of cattle from lumpy skin disease.

Lumpy Skin Disease(LSD) had affected the cattle on a large scale in July, 2022. About 1.75 lakh cattle were affected across the Punjab state and about 18,000 cattle died.

Lumpy Skin Disease(LSD)

  • A viral disease affecting cattle or water buffalo caused by the Lumpy Skin Disease Virus (LSDV)
  • Causes: Infection with LSDV
  • Mortality rate: Less than 10% according to FAO
  • First outbreak: Zambia in 1929
  • Transmission: Primarily spread by vectors like mosquitoes and flies
  • Symptoms: Fever, discharge from eyes and nose, drooling, blisters on skin, loss of appetite, reduced milk production
  • Prevention: Administering goat pox and sheep pox virus vaccines (heterologous vaccine), development of live attenuated vaccine (Lumpi-ProVacInd) providing 100% protection
  • Treatment: Supportive care, wound care sprays, antibiotics to prevent secondary infections, anti-inflammatory painkillers to increase appetite

21-Jan-2023: Researchers have proposed a “Pan-transcriptome” which combines transcriptome with pan-genome

Mapping transcriptome (complete set of RNA molecules) allows researchers to better understand an individual’s gene expression.

Pan-Transcriptome

  • It is a Combination of a transcriptome and a pan-genome
  • Transcriptome: Complete set of RNA molecules in a cell or tissue, produced by the genetic material of an organism
  • Pan-genome: Reference containing genetic material from a diverse group of individuals

Uses

  • Discovery of new genes: Can be used to identify novel genes that may not have been detected through traditional genome sequencing methods.
  • Regulating gene expression: Pan-transcriptome can change in response to environmental or physiological conditions, and it plays a key role in regulating gene expression.
  • Characterizing genetic diversity: Pan-transcriptomes can be used to identify genetic variations within and between different populations of organisms. This can provide insights into the evolution and adaptation of different species.

RNA Mapping

Technique used to identify and map the location of RNA molecules within a cell or tissue. Typically used to study the expression and localization of different types of RNA, including messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).

Types:

In-situ hybridization (ISH)

  • Allows researchers to see where a specific RNA is located within a cell or tissue
  • Provides insights into the function of that RNA

RNA-seq (RNA sequencing)

  • Simultaneous analysis of thousands or even millions of RNA molecules in a sample
  • Can generate a detailed picture of the transcriptome, including the abundance and location of different RNA molecules

Uses

  • Study gene expression patterns
  • Identify novel transcripts
  • Detect genetic variations
