Species targeted: Pigs;
Age: Young;
Summary:
A study was done to measure the effects of quaternary benzo(c)phenanthridine alkaloids (QBAs) against Salmonella spp and determine effects on growth performance, organism shedding, and gastrointestinal tract integrity in pigs inoculated with Salmonella Typhimurium. Pigs were inoculated with Salmonella organisms and placed in 4 groups: receiving diets supplemented with 1.5 g of QBAs/1,000 kg of feed, 0.75 g of QBAs/1,000 kg of feed, or 59.4 g of chlortetracycline/1,000 kg of feed or a nonsupplemented diet. Diets containing QBAs decreased Salmonella spp shedding; shedding was lower 40 days after inoculation for pigs fed diets containing QBAs or chlortetracycline. Growth performance was similar for pigs fed diets containing QBA or chlortetracycline. Gastrointestinal tract integrity improved in pigs fed the diet containing 1.5 g of QBAs/1,000 kg of feed.QBAs and chlortetracycline decreased Salmonella spp shedding but did not differ regarding growth performance. Gut integrity was slightly better in pigs fed diets containing QBAs.

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 \ New antibiotics; Feed / gut health
Species targeted: Pigs;
Age: Young;
Summary:
The effects of eucalyptus-medium chain fatty acids (E-MCFAs), zinc oxide (ZnO), and antibiotics on performance, nutrient digestibility, and serum chemistry parameters of were studied in nursery pigs. Three experiments were conducted. Recently weaned pigs, were given five treatments consisting of a basal diet or the basal diet supplemented with antibiotics (33 mg per kg tiamulin and 44 mg per kg lincomycin), ZnO (1500 or 2500 mg per kg), or 0.1% E-MCFAs (Experiments One and Two). In Experiment Three, 1% diatomaceous earth was added and the negative control was not used. In all three experiments, performance of pigs fed the four supplemented diets did not differ. Digestibility was higher in the diet supplemented with E-MCFAs than in diets supplemented with ZnO or antibiotics. This study indicates eucalyptus-MCFAs can be successfully used as a growth promoter in diets fed to nursery pigs.

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements; Specific alternatives
Species targeted: Pigs;
Age: Young;
Summary:
This study aimed to evaluate the effects of dietary Brazilian red pepper essential oil and an antimicrobial agent on weanling pig growth performance, diarrhea, pH of the digestive content, small intestine cells, and intestine microbial counts. Ninety weanling castrated male pigs were given five treatments: a diet supplemented with 0 (negative control), 500, 1000, and 1500mg/kg Brazilian red pepper essential oil vs with 120mg/kg chlorohydroxyquinoline (antibiotic). Treatments had no effect on growth performance, diarrhea occurrence, pH of the digestive content, gut mucosa and intestinal microbial counts of weanling pigs. However, pigs fed the diet containing 500mg/kg essential oil had thicker gut mucosa than those fed diets containing the antibiotic or 1000 and 1500 mg/ kg essential oil. Thus, Brazilian red pepper essential oil and the antibiotic are of limited benefit for enhancing the growth of weanling pigs. Nonetheless, the effectiveness of growth enhancer additives may be reduced in non-challenging situations.

In Significant Impact Groups: Specific alternatives \ Pre-/probiotics
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep; Other;
Age: Young; Adult;
Summary:
In the last years there has been substantial interest on the use of aromatic herbs and essential oils as feed additives in animal nutrition. Significant antimicrobial effects of several essential oils and compounds against gut organisms in farm animals have been shown. Specific Escherichia coli strains could be controlled by in-feed application of carvacrol-rich essential oils, and the effect of some essential oil components against Clostridium perfringens and necrotic enteritis was confirmed in poultry. In ruminants, an improvement of the digestion was observed. Aromatic plants and essential oil compounds improve stability and palatability of animal feed and improved shelf-life and quality of animal products. The ‘growth-promoting effect’ of essential oils is not as evident. Nonetheless, the overall efficacy of essential oils and aromatic herbs, especially their impact on the health status and benefit of animals and humans (via the food chain) is encouraging further research and development in this field.

In Significant Impact Groups: Specific alternatives \ New antibiotics
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep; Other;
Age: Young; Adult;
Summary:
It is a common practice for decades to use of sub-therapeutic dose of antibiotics in food-animal feeds to prevent animals from diseases and to improve production performance in modern animal husbandry. Concerns over the increasing emergence of antibiotic-resistant bacteria have prompted efforts to develop so-called alternatives to antibiotics. This review summarizes recent development and perspectives of alternatives to antibiotics. The mechanism of actions, applications of the alternatives such as immunity modulating agents, bacteriophages and their lysins, antimicrobial peptides, pro-, pre-, and synbiotics, plant extracts, inhibitors targeting pathogenicity, and feeding enzymes are discussed. Lastly, the feasibility of these alternatives is analyzed. The conclusion is that these alternatives are not likely to replace antibiotics in animals in a foreseeable future. Therefore, prudent use of antibiotics and the establishment of scientific monitoring systems are the best and fastest way to limit the adverse effects of overuse of antibiotics.

Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age:
Summary:
Veterinarians are encouraged to check and consider EMA’s updated scientific advice on the categorisation of antibiotics when prescribing these medicines for animals in their care. This categorisation can also be used as a tool for the preparation of treatment guidelines. The classification now comprises four categories, from A to D: Avoid, Restrict, Caution and Prudence. Category A: These medicines may not be used in food-producing animals and may be given to individual companion animals only under exceptional circumstances. Category B: The use of these medicines in animals should be restricted to mitigate the risk to public health. Category C: These antibiotics should only be used when there are no antimicrobial substances in Category D that would be clinically effective. Category D: These antibiotics can be used in animals in a prudent manner.

In Significant Impact Groups: Water \ Water quality
Species targeted: Pigs;
Summary:
Good quality drinking water is an important prerequisite for livestock. Experience shows that the water entering the company is of excellent quality. Afterwards, however, until the water is absorbed by the animal, the bacteriological and chemical quality often deteriorates. Drinking water of bad quality has effects on animal health and can therefore be a cause of lower production or slower growth!
On behalf of VION and LIB, ZLTO has developed a checklist together with a number of pig farmers in order to be able to monitor the quality of the drinking water itself.
With the checklist you can find out where you can improve the drinking water supply and there are tips on how to do this.
Go through all the sections if you want to know where improvements are possible. If you already know where you can make improvements, take a look at the extra tips.

In Significant Impact Groups: Housing and welfare
Species targeted: Pigs;
Summary:
Since mid-June 2020, welfare checks for sucking piglets, weaned piglets, fattening pigs and rearing sows have been available on www.welzijnscheckvarkens.nl. They show the risks of welfare problems on the farm per animal category.
This concerns in particular the risk assessment of the biting behaviour of pigs. The indicators (animal-bound and non-animal-bound) that influence the bite behaviour are assessed. The aim of the risk assessment is to improve animal welfare, animal health and overall operating results.
Purchasers in the Netherlands and abroad place high demands on the animal welfare of pigs. The welfare check for pigs has been developed to demonstrate good animal welfare. It also enables pig farmers to properly identify the risk of biting their pigs’ flanks, ears or tails.

247 Industry Innovation – Pain relief during castration of piglets by Lintjeshof

In Significant Impact Groups: Housing and welfare
Species targeted: Pigs;
Age: Young;
Summary:
Pain relief during castration is not compulsory in all countries, including the Netherlands. Pig breeders who are perfect in pain management should administer the anaesthetic half an hour before castrating the piglet. There are also pig farmers who administer pain relief at the same time as other piglet treatments. With complete pain management, the piglet recovers faster. A point of attention is to give the piglets the correct anaesthetic with the concentration suitable for piglets. The injection is rewarding, but the operation requires some adaptability on the part of the pig farmer. Pain management costs roughly 2 cents per piglet.
