In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Pigs;
Age: Young; Adult;
Summary:
A number of feed additives are marketed to assist in boosting the pigs’ immune system, regulate gut microbiota, and reduce negative impacts of weaning and other environmental challenges. The most commonly used feed additives include acidifiers, zinc and copper, prebiotics, direct-fed microbials, yeast products, nucleotides, and plant extracts. Inclusion of pharmacological levels of zinc and copper, certain acidifiers, and several plant extracts have been reported to result in improved pig performance or improved immune function of pigs. It is also possible that use of prebiotics, direct-fed microbials, yeast, and nucleotides may have positive impacts on pig performance, but results have been less consistent and there is a need for more research in this area.

In Significant Impact Groups: Feed / gut health \ Feed composition
Species targeted: Pigs; Poultry;
Age: Not stated;
Summary:
Processing livestock feed influences gut health/function, efficacy of feed enzymes and nutrient availability. Finer feed particles allow better absorption of nutrients (increased surface area allowing better contact with digestive enzymes) and enhance animal performance. There is a limit to the particle size; very fine particles negatively affect gut health, i.e. stomach ulceration in pigs and gizzard dysfunction in poultry. Coarse particle size increases stomach and hindgut acidification, which may be beneficial in controlling overgrowth of gut bacteria, such as salmonella and E. coli. However, since most commercial pig/poultry diets are subject to heating to reduce levels of feed-borne bacteria (e.g. Salmonella) reduction of feed particle size is inevitable. However, achieving high nutritional quality and processing at high temperatures does not favour high nutrient availability and stability of heat sensitive enzymes. Therefore, feed processing balance maximum nutrient utilization, feed hygiene status, stability of enzymes post-processing and impact on gut health.

Age: Young;
Summary:
Synthetic porcine beta-defensin-2 (pBD-2) was tested as an alternative to antimicrobial growth-promoters in pig production. Thirty 21-day weaned piglets were challenged with Escherichia coli, and orally dosed with either sterile water (CON), pBD-2 (BD) or neomycin sulphate (NS) twice daily for 21 days. Therefore, pBD-2 has antimicrobial activity in piglets, and it can improve growth performance, reduce inflammatory cytokine expression and affect intestinal morphological indices in the same way as probiotics. Moreover, pBD-2 has a more positive effect on intestinal morphological indices and intestinal probiotics of piglets than does NS. Therefore, the present results suggest that pBD-2 may be a suitable replacement for NS in piglets.

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements; Specific alternatives
Species targeted: Pigs;
Age: Young;
Summary:
This study evaluated the effects of hop (Humulus lupulus) beta-acids or colistin on several parameters, namely body weight (BW), Average feed intake (ADFI) Average daily gain (ADG), gain:feed ratio (G:F). Two hundred 21-d weaned pigs fed diets supplemented with 0 (negative control), 120, 240, or 360 mg/kg hop beta-acids, or with 40 mg/kg colistin (antimicrobial control) during a 35-d experiment. Increasing dietary levels of hop beta-acids improved linearly BW, ADG, G:F,and digestibility in weanling pigs. The colistin treatment improved BW, ADG, and G:F compared to the negative control. No difference in growth performance was observed between hop beta-acids levels and colistin. Overall, the occurrence of diarrhea was lower for colistin, negative control, and 360 mg/kg hop beta-acids than for other levels. In conclusion, dietary hop beta-acids concentrations up to 360 mg/kg improved weanling pig growth rate by affecting the efficiency of feed utilization, as well as observed for colistin.

288 Research paper – Huang – 2010 – Effects of dietary allicin on health and growth performance of weanling piglets and reduction in attractiveness of faeces to flies

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Pigs;
Age: Young;
Summary:
The effect of allicin on health and growth performance of weanling piglets was investigated at 21 days of age. Two hundred and twenty-five piglets were weaned and allocated into five groups. Piglets in the control group were fed diets supplemented with antibiotics. In the treatment groups pigs were fed diets without antibiotics, but supplemented with allicin product (25% pure allicin oil) with 0.10 g/kg, 0.15 g/kg, 0.20 g/kg and 0.25 g/kg in the diet, respectively. After 28 days, the average daily weight gain increased as the level of dietary allicin increased; whereas feed gain ratio, the incidence of diarrhoea in the treatment piglets decreased (especially female piglets) and the number of flies on the surface of the faeces decrease with increased allicin. In conclusion, diets with allicin may improve growth performance, reduce the incidence of diarrhoea and improve their local environmental conditions due to lower number of flies.

In Significant Impact Groups: Specific alternatives \ Pre-/probiotics Feed / gut health
Species targeted: Poultry;
Age: Young;
Summary:
Reducing the use of antibiotics is a major challenge for the poultry sector. This work aims at assessing the efficiency of several different forms of food additive on technical performances and health status of Label Rouge broilers, produced in sub-optimal conditions (eggs storage before incubation for 18 days and distribution of less digestive food with essential amino-acid deficiency). The effects of pre-starter, rehydrating, and combination of the two products are tested for the first two days of rearing. The (day-old) chick quality, measured according to 8 criteria, is negatively impacted by the storage duration before incubation. For the first 2 days, the pre starter effect is positive. Its usefulness is clear when this is combined with the rehydrating association. The supplementation from 7 to 12 days has improved the broiler feed efficiency. For the second part of rearing (15-76 days), technical results are not significantly different regardless of treatments.

214 Industry Innovation – Essential Oils in Drinking Water_ Using Flexibility and Speed to Help Poultry During Gut Health Challenges by Biomin

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Poultry;
Age: Adult;
Summary:
While adding phytogenic feed additives (PFAs) to feed is the most common application method, many producers are realizing the benefits of including PFAs in drinking water. PFAs can be used to tackle necrotic enteritis (NE) in poultry, a challenge likely to result in decreased feed intake. Bans on the use of antibiotic growth promotors in livestock production around the world have resulted in a performance gap. Phytogenic feed additives (PFAs) can help bridge the gap due to their beneficial biological effects. Drinking water application of PFAs (example of Digestarom® P.E.P. sol.) ensures they are delivered to the gut during times when they are most needed. Drinking water application of PFAs is flexible and quick and is increasing in popularity. Application can take place in combination with other additives such as organic acids, probiotics, or vaccines. Improved broiler gut quality and function results in reduced disease incidence and less treatment costs.

Species targeted: Poultry;
Age: Adult;
Summary:
Even with good management, bacterial infections stemming from the imbalance of the gut microbiota can cause production losses in layers. Preventive nutrition strategies that support gut performance can offer a cost effective alternative to antibiotic application, particularly around peak production. In fact, unsaleable eggs and the challenge of drug-resistant bacteria can make antibiotic application more expensive than non-antibiotic alternatives. Organic acids and phytogenic feed additives have been accepted as an efficient tool to prevent and control disease proliferation in poultry. The case of a commercial layer farm in Hungary illustrates how preventive nutritional strategies using novel feed additives can offer a profitable alternative to antibiotics in cases of chicken disease.

SIG: Feed / gut health \ Feed additives and supplements
Species targeted: Poultry;
Age: Adult;
Summary:
Banning preventive in-feed antibiotics has increased risks for outbreaks of necrotic enteritis, predisposing from coccidiosis and overloads of nutrients in the intestine. Coated butyrate can be a valuable in-feed additive for broilers to prevent feed intake reduction as a consequence of coccidiosis and necrotic enteritis (NE). Different dietary strategies can be used to fight coccidiosis. Some products act antimicrobially against Eimeria species, e.g. essential oils and herbal extracts. Other products beneficially modulate the immune status of the chicken, whereas prebiotics and probiotics improve microflora to reduce the chance of secondary infections. The immunological challenge from coccidiosis and C.perfringens, makes the barrier function of the gut layer extremely important. Butyrate is a short-chain fatty acid that enhances the chickens’ intestinal functioning, promoting development, maintaining the barrier functioning and acts as anti-inflammatory agent. Proper coating results in butyrate reaching both upper and lower parts of the intestine to exert its positive effects.

SIG: Feed / gut health \ Feed additives and supplements; Pathogen management
Species targeted: Pigs;
Age: Adult;
Summary:
Despite current control measures, Salmonella in pigs remains a major public health concern. In this in vivo study, the effect of three intervention strategies on Salmonella Typhimurium transmission in pigs was evaluated. The first intervention was feed supplemented with coated calcium-butyrate, the second comprised oral vaccination with a double-attenuated Salmonella Typhimurium strain, and the third was acidification of drinking water with a mixture of organic acids. Both feed supplementation with coated calcium-butyrate and vaccination with an attenuated vaccine decreased Salmonella Typhimurium transmission in pigs. Further studies are needed to assess the practical issues related to the implementation of these interventions. For example, more data are needed to determine the best age groups and treatment regimens for the coated calcium-butyrate and to learn how to overcome the problem of Salmonella-specific antibodies in vaccinated pigs.
