Effect of in ovo injection of raffinose on growth performance and gut health parameters of broiler chicken

Abstract Maintaining a healthy gastrointestinal tract (GIT) is critical for better nutrient utilization, optimum performance, and overall health of poultry. Thus, several nutritional strategies have been tried to improve poultry’s gut health. More recently, different nutrients and feed additives are being used in poultry diets with some success when antibiotic growth promoters (AGP) are not an acceptable option anymore. However, effective modulation of gut health depends on the methods and timing of the compound being available to host animals. Routinely, the alternatives to AGP like prebiotics, probiotics, symbiotic, enzymes, and other nutrients are provided in feed or water to poultry. However, the GIT of the newly hatched poultry is functionally immature, despite going through significant morphological, cellular, and molecular changes toward the end of incubation. Thus, the early growth and development of GIT are of critical importance to enhance nutrients utilization and optimize the growth performance of poultry. Maternal nutrition and in ovo feeding have been used and found to be effective in improving gut health but with inconsistent results. The effects of maternal nutrition on the development and viability of embryo and post-hatch growth performance of birds are documented. However, there is limited information on how maternal nutrition affects the gut health of chicks. In contrast, information on the same from in ovo feeding of nutrients and feed additives has increased in recent years. The results show that in ovo feeding can be a good tool to modulate gut health of post-hatch birds positively. However, more information is needed on the proper route and time of inoculation, optimum doses, and effective combination of different compounds to maximize the benefits of in ovo feeding technique in poultry production.

AbstractDue to the threat and emergence of bacterial resistance against antibiotics, the use of in-feed antibiotics at therapeutic and subtherapeutic levels has been limited. Complete withdrawal of antibiotics as growth promoters (AGP) has led to poor gut health signs in chickens that include conditions like wet litter, intestinal bacteria overgrowth, poor growth performance, malabsorption and various diseases. Two of the most common alternatives to AGP are prebiotics and probiotics. Both prebiotics and probiotics have become the potential feed additives that improve the gut health, immune system and microbiota by various mechanisms of action, and enhance growth performance of chickens. The review discusses the modes of action like antibacterial, competitive exclusion (CE), and immunomodulatory properties of prebiotics and probiotics, particularly in poultry.In ovofeeding of prebiotics and probiotics with promising effect on growth performance and reduction of pathogens likeSalmonellais also discussed in this review. However, it is necessary to conduct more research with prebiotics and probiotics as well as other feed additives to understand the detailed mechanisms of action and identify better alternatives for poultry production and health.

The present study was conducted to investigate the effects of probiotic on growth performance, gut health, viability, carcass yield traits and cost benefit analyses etc., of broiler chicken from d1-28 days. A total of 192 day-old broiler chicks (Ross 308) was assigned into four dietary treatment groups, i.e. D1 (Control), D2 (Poultry Starsol), D3 (Avilac plus) and D4 (Avibac), and each treatment replicated six times with eight birds per replicate in a completely randomized design. The chicks were raised in battery cages all the trial period. Ready-made starter diet (crumble) was fed the chicks up to 14 days, after that, grower (pellet) diet fed the broiler from d15 to 28 days. The water treated with probiotics at the rate of 1.0 g L-1 (Poultry Starsol), 1.0 ml L-1 (Avilac plus) and 1.0 g L-1 (Avibac) in D2, D3 and D4 treatment groups, respectively, and supplied the birds ad libitum entire the trial period. Data on feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR) and livability (%) were collected. Apart from this, caecal digesta sample was taken on 28 days to determine the gut microflora population, i.e. total viable count (TVC) and total lactobacilli count (TLC) of broilers. Carcass characteristics (dressing %, blood weight, drumstick weight, thigh weight, breast weight %) and cost benefit were also calculated on the last day of trial period to assess the different meat cuts and the profitability of broiler. The data revealed that FI, viability (%), TVC and TLC of broilers had no difference (P>0.05) between treatment on 28d. Except for first week, BWG was improved significantly (P<0.05) in the birds fed probiotics during d1-21 and d1-28, respectively. Superior FCR values (1.30, 1.34) were observed in the broilers of probiotics supplemented groups from d1-28 days of age. The results of carcass traits were influenced significantly (P<0.05) by dietary treatment. The percentage of breast weight, thigh weight, dressing yield, drumstick weight and blood weight was increased (P<0.05) in the supplemental group compared to control. Higher (P<0.01) net profit was observed in the birds of probiotics supplemented group than that of control group. It can be concluded that broiler responded positively as a result of probiotics supplementation in water, and can be raised profitably under farming condition with low cost. Int. J. Agril. Res.
