The report highlights trends prevailing in the market, and drivers and restraints pertaining to the laboratory animal diet market.

Mice models are essential tools for studying the pathogenesis of infectious diseases and the preclinical evaluation of vaccines and therapies against various human pathogens. The use of genetically defined inbred mouse strains, humanized mice, and gene knockout mice has enabled the research community to study how pathogens cause diseases and explain the role of specific host genes in controlling or promoting diseases. It also helps determine potential targets for the prevention, identification, or treatments for various infectious agents .

With the emergence of new infectious diseases, the animal model has become a vital tool for studying disease mechanisms and developing therapeutics. Mice with xenografted human immune systems have been used to study the pathogenesis of various infectious agents, including Plasmodium falciparum (malaria), Mycobacterium tuberculosis, dengue virus, and influenza virus. These models have been beneficial in studying HIV, which includes analyzing viral and host factors that promote viral replication and HIV interactions with the host's immune response. They are also helpful as platforms for testing therapeutic approaches to control HIV infection.

Mouse models are widely used for preclinical screening of vaccines/therapies because of their reproducibility, low cost, and ease of experimental manipulation. Over the past century, advancements in vaccines, antibiotics/antivirals, and infection control measures have significantly reduced the burden of infectious diseases on public health. However, there has been an increase in contagious viral diseases.

Mouse models are considered the best small animal models to be tested for hepatitis B virus (HBV), hepatitis C virus (HCV), Zika virus, SARS-CoV-2, and cytomegalovirus (CMV). According to the WHO, more than 17 million deaths are reported yearly due to infectious diseases. Over the past two decades, over 30 new infectious diseases have emerged. According to UNAIDS, 38 million people were affected by HIV by the end of 2019. Mouse models have been widely used for various viral studies due to their small size, low cost, ease of use, and high reproducibility. To study the effect of the vaccines and therapies, these laboratory mice models are given a standardized diet according to the need of the mice model. The prevalence of viral and infectious diseases drives the need for mice models. As a result, there is an increasing demand for specific diet for the mice models, which bolsters the growth of the laboratory animal diet market.

North America held the largest share of the laboratory animal diet market in 2021. The market in the US was valued at US$ 1,382.80 million in 2021 and is expected to reach US$ 1,938.06 million by 2028; it is expected to grow at a CAGR of 4.9% during the forecast period. The growth of the market in the country is attributed to the development and introduction of personalized medicine products and services emerged mainly in the US. Concerns regarding the adverse effects of certain drugs and the desire to increase patient participation in medical decisions have the potential to speed up the acceptance of personalized medicine in the country. Rapid developments in regenerative medicine and tissue engineering have witnessed an increasing inclination toward clinical translation on animal model, which is fueling the demand for laboratory animal diet across the US. However, Asia Pacific is expected to register the highest CAGR during the forecast period.

The COVID-19 outbreak significantly increased the demand for mice models for the research & development of vaccines and antiviral drugs. A large number of animal models were required to verify the safety and efficacy of new entities before conducting human trials. The market demand for COVID-19 mouse models was on a rise during the pandemic, especially for humanized ACE2 (hACE2) mice, which express human ACE2 in the airway and other epithelia and develop a lethal SARS-CoV infection. However, the supply was limited, as mice model providers do not have handy populations to meet rising demand. Additionally, due to the pandemic, many research institutions were bound to shut down and were unable to operate normally, which hindered the laboratory animal diet market. Considering the situation as described above, in the short term, the pandemic has negatively impacted the market due to import and export restrictions. However, in the long term, governments and scientific research institutions in various countries were bound to increase research investments in treatments and vaccines against infectious diseases, which would propel the demand for laboratory animal diet in the coming years.
