In Hawaiʻi , there is a relatively high number of feral chickens, commonly seen on roads and in parking lots. These feral chickens are of scientific interest, as they can provide clues about the modern-day chicken’s biology. However, until now, there was limited or no knowledge of the gut microbiota of these feral birds. That’s according to Professor Rajesh Jha of the University of Hawaiʻi at Mānoa College of Tropical Agriculture and Human Resources ( CTAHR ) Department of Human Nutrition, Food and Animal Sciences . For the first time, Jha’s research team sequenced the intestinal microbiota of the Hawaiian feral chicken and explored the cecal (referring to a specific part of the intestine) microbiota profile of commercial chickens. “Since microbial populations are instrumental to their host’s health, we hope that our work will help determine what bacteria are dominant and what potential roles they play, either beneficial or non-beneficial,” said Jha. Knowing the healthy gut mic...

This study was carried out to evaluate the efficacy of Fenugreek seeds ( Trigonella foenum-graecum L.) on overall performance of broiler. A total of 96-day old Cobb-500 chicks were randomly divided into four dietary treatment groups namely T0, T1, T2 and T3 having three replications in each treatment group. Brooded chicks were randomly separated into replications wise separate pen to rear up to 4 weeks. Each treatment group contains 24 birds (8 birds in each replication). Experimental birds in T1, T2 and T3 were provided fenugreek seeds meal with 0.5%, 1% and 1.5% of feed while T0 was provided with standard feed and considered as control group. The results of this study were indicated that final live weight gain and feed efficiency of birds was significantly (P<0.05) higher in T3 compared to T2, and T0 respectively. The result also indicated that feed efficiency was increased at dose rate of 1.5% fenugreek seeds meal in T3 compared to T2, T1 and control T0 group respectively. In ca...

Poultry, also recognized as universal food, as poultry meat and eggs enjoy zero religious’ restrictions, unlike pork and beef. Being universal and accepted by all religions, the demand of poultry increased globally hence the trend of rearing is also increased. Poultry meat and eggs are main source of protein, household nutrition and income in developing countries. In Somali economy, still the Livestock sector act a crucial component and become a backbone. Like other countries, the poultry production in Somalia is also an important component of the livestock sub-sector. Development of the poultry sub-sector contribute in income foreign currency, employment, food and nutrition security, and women’s economic employment in rural areas. In Somalia, Poultry keeping is widespread among poor house-holds and now commercial poultry farming is also on the rise, particularly in urban areas. Hence, a retrospective study was designed to investigate the prevalence of poultry diseases in southern Soma...

Diverse gut microbiota plays a significant role in host metabolism, growth performance, nutrient digestion, and overall health of birds. The composition of chicken gut microbiota depends on age, especially at the early stages of life, genotype, farming conditions/environment, and diet/feed additives. Sometimes, the gut microbiota composition can be altered severely by non-infectious or infectious stressors. Consequently, this dysbiosis can impact intestinal morphology and activities (e.g., increased permeability of the intestine, higher risk of bacterial infection, sepsis, inflammation, and reduced digestion). Probiotics can affect the health, performance, and disease risk of the hosts, as they can amend the dysbiosis and improve the balance of gut microbiota in healthy hosts by reducing the proliferation of pathogenic species and increasing the beneficial bacteria. The most commonly used probiotic species belong to the genera Lactobacillus ,  Streptococcus ,  Bacil...

But livestock producers may want to reconsider that stance. That’s according to Associate Professor Rajesh Jha of the University of Hawaiʻi at Mānoa College of Tropical Agriculture and Human Resources Department of Human Nutrition, Food and Animal Sciences . “Our lab has studied many alternative feed components for developing cost-effective and sustainable animal production systems and, in the process, found many functional benefits of dietary fiber not previously appreciated,” Jha noted. Although fibrous feedstuffs typically have fewer calories and relatively lower nutritional values, the higher level of dietary fiber works to improve the animal’s gut health by modulating beneficial microorganisms in the large intestine, the same way as in humans. This benefits the immune function, as well as ove...

Addition of color in food materials are common and widely used to maintain the real color and sometime to preserve it. Synthetic dyes have become more popular for several reasons but these dyes act as a potential source of various diseases from simple skin allergies to serious cancer. “So, alternative natural sources for pigments are needed,” says Assistant Professor Maria Afroz Toma of Department of Food Technology and Rural Industries, Bangladesh Agricultural university, Bangladesh. “Our recent study suggest that soil-borne fungi are the good source of natural pigments for food industry which are more cost-effective and can be harvested throughout the year with no side effects, as well as being eco-friendly and biodegradable” Toma noted. “Using of pigment in food products extracted from soil-borne Aspergillus niger in Bangladesh is very new and so far this is the first attempt, but for industrial use, the food colorants must be approved by a responsible authority, e.g., the FDA or th...

Probiotics are live microorganisms which, when administered in adequate amounts, confer health benefits to the host. The use of probiotics in poultry has increased steadily over the years due to higher demand for antibiotic-free poultry. The objective of this systematic review is to present and evaluate the effects of probiotics on the nutrient utilization, growth and laying performance, gut histomorphology, immunity, and gut microbiota of poultry. An electronic search was conducted using relevant keywords to include papers pertinent to the topic. Seventeen commonly used probiotic species were critically assessed for their roles in the performance and gut health of poultry under existing commercial production conditions. The results showed that probiotic supplementation could have the following effects: (1) modification of the intestinal microbiota, (2) stimulation of the immune system, (3) reduction in inflammatory reactions, (4) prevention of pathogen colonization, (5) enhancement of...
