Recent Advances in Probiotic Application in Animal Health and Nutrition: A Review

Biotechnological advances in animal health and nutrition continue to play a significant role in the improvement of animal health, growth, and production performance. These biotechnological advancements, especially the use of direct-fed microbials, also termed probiotics, those genetically modified and otherwise, have minimized many challenges facing livestock production around the world. Such advancements result in healthy animals and animal products, such as meat, for a growing population worldwide. Increasing demand for productivity, healthy animals, and consumer food safety concerns, especially those emanating from excessive use of antibiotics or growth promoters, are a driving force for investing in safer alternatives, such as probiotics. The advent of vastly diverse pathogens and bacterial organisms, some of which have acquired antimicrobial resistance due to therapeutic use of these antibiotics, has had a negative impact on the animal and food industries. Probiotics have been chosen as substitutes to counter this excessive use of antibiotics and antibiotic resistance. Over the last decade, probiotics have gained recognition, increased in importance, and stimulated growing interest in the animal health and nutrition industry. Probiotics are considered to be favorable live microorganisms by the host organism by maintaining microbial homeostasis and healthy gut, and can be a viable alternative to antibiotics in addition to providing other growth-promoting properties. Even though various studies describe the modes of action of probiotics, more research is needed to illuminate the exact mechanism of action of probiotics and how they benefit the host. This review describes the importance of probiotics in animal health, nutrition, and in growth and production performance. It also provides a thorough review of recent advances in probiotics research and application in animal health and nutrition and future directions on probiotic research to enhance animal performance

A study to investigate the uptake of digital technology in Ruben FM radio station

Having realized the potential of digital technologies, radio stations in Kenya have embraced technology to improve “interactivity with their listeners”. However, the extent to which digital technologies are used at radio stations and existing challenges and opportunities in uptake is yet to be established. The research\u27s primary goal was to investigate technology uptake in Ruben FM radio stations. Specifically, the study sought to examine the extent of use of the existing digital technologies in Ruben FM radio station, explore other digital technology opportunities for uptake in Ruben FM radio station and establish challenges facing digital technology uptake in Ruben FM radio station. The study was based on Technology Acceptance Model (TAM). The study adopted a cross-sectional research design. The target and sample size were 20 employees at Ruben FM. The primary data was collected using both questionnaires and focus group discussions. Quantitative data were analysed using descriptive statistics such as frequencies, mean and standard deviation. Qualitative data generated from open-ended questionnaires and focus group discussions were analysed using content analysis. The study established that existing digital technologies are used daily to a greater extent at Ruben FM, including social media sites like Facebook, WhatsApp, twitter, Instagram and YouTube, podcasts, and radio websites. The study found various challenges facing digital technology uptake by Ruben FM radio station. These include power supply interruptions and limited access to the internet, among others. The study recommended that the management of Ruben FM radio station should ensure the installation of a backup generator to solve power supply interruptions. The study also recommended that the management of Ruben FM radio station should create an offline radio mobile app that will enable more people with android phones to access radio programs without using the internet

A Review on Effects of Aloe Vera as a Feed Additive in Broiler Chicken Diets

Prohibition of application of antibiotic growth promoters in broiler chicken diets has resulted in increased use of herbs as natural additives in broiler feeds over the recent years. Researchers particularly look for herbs that can affect such parameters as growth performance, immune response, or treatment of certain diseases. Aloe vera is a well-known herb characterized by properties such as anti-bacterial, anti-viral, anti-fungal, anti-tumor, anti-inflammatory, immunomodulatory, wound-healing, anti-oxidant, and anti-diabetic effects. During the past years, attention has shifted toward Aloe vera as a natural additive to broiler diets, and studies have shown that Aloe vera can improve immune response and growth performance in broilers. In addition, Aloe vera is an excellent alternative for antibiotic growth promoters and anticoccidial drugs. Since Aloe vera can be used for broilers in the form of gel, powder, ethanolic extract, aqueous extract, and a polysaccharide contained in Aloe vera gel (i.e. acemannan), more studies are required to determine the best form and to compare Aloe vera with other medicinal herbs. This paper reviews effects of Aloe vera on intestinal microflora, growth performance, immune response, and coccidiosis in broiler chickens

Growth performance and carcass characteristics of guinea fowl broilers fed micronized-dehulled pea (Pisum sativum L.) as a substitute for soybean meal

This study was conducted to evaluate the effect of substitution of soybean meal (SBM) with dehulled-micronized peas (Pisum sativum) in diets of guinea fowl broilers on their growth performance, car- cass yields, and fatty acid composition of meat. One hundred forty 1-d-old guinea fowl keets were randomly assigned to 2 dietary treatments, which were fed from hatch to 12 wk. The birds were fed 2 wheat middling- based diets comprising a control diet, which contained SBM (78 g/kg) and a test diet containing dehulled- micronized peas (180 g/kg) as the main protein source. The substitution of SBM with peas had no adverse ef- fect on growth performance, dressing percentage, or breast and thigh muscle relative weights of the guinea broilers. However, a reduction of abdominal fat content (P < 0.05) was observed in birds fed the pea diet com- pared with the control. Breast and thigh meat of birds fed the pea diet had higher lightness scores (P < 0.05) and water-holding capacity (P < 0.01) than the control. Meat from guinea fowls fed the pea diet had less choles- terol (P < 0.01) and lipids (P < 0.05), and higher con- centrations of phospholipids (P < 0.05). Feeding peas increased polyunsaturated fatty acid concentration in breast and thigh muscles, and decreased the saturated fatty acid concentration. Feeding the pea diet also low- ered the n-6/n-3 polyunsaturated fatty acid ratio of the guinea broiler muscles. Our results suggest that replac- ing the conventional SBM as the protein source with dehulled-micronized pea meal in diets of guinea fowls broilers can improve carcass quality and favorable lipid profile without adversely affecting growth performance traits

Recent Advances in the Application of CRISPR/Cas9 Gene Editing System in Poultry Species

CRISPR/Cas9 system genome editing is revolutionizing genetics research in a wide spectrum of animal models in the genetic era. Among these animals, is the poultry species. CRISPR technology is the newest and most advanced gene-editing tool that allows researchers to modify and alter gene functions for transcriptional regulation, gene targeting, epigenetic modification, gene therapy, and drug delivery in the animal genome. The applicability of the CRISPR/Cas9 system in gene editing and modification of genomes in the avian species is still emerging. Up to date, substantial progress in using CRISPR/Cas9 technology has been made in only two poultry species (chicken and quail), with chicken taking the lead. There have been major recent advances in the modification of the avian genome through their germ cell lineages. In the poultry industry, breeders and producers can utilize CRISPR-mediated approaches to enhance the many required genetic variations towards the poultry population that are absent in a given poultry flock. Thus, CRISPR allows the benefit of accessing genetic characteristics that cannot otherwise be used for poultry production. Therefore CRISPR/Cas9 becomes a very powerful and robust tool for editing genes that allow for the introduction or regulation of genetic information in poultry genomes. However, the CRISPR/Cas9 technology has several limitations that need to be addressed to enhance its use in the poultry industry. This review evaluates and provides a summary of recent advances in applying CRISPR/Cas9 gene editing technology in poultry research and explores its potential use in advancing poultry breeding and production with a major focus on chicken and quail. This could aid future advancements in the use of CRISPR technology to improve poultry production
