Abstract Background The efficacy of a novel inactivated intradermal Lawsonia intracellularis vaccine, Porcilis® Lawsonia ID, was evaluated in two experimental vaccination-challenge studies and under field conditions on a farm with a history of recurrent acute ileitis. In addition, the efficacy of the vaccine was compared to that of a commercially available live attenuated vaccine. The novel inactivated vaccine consists of a freeze-dried antigen fraction that is dissolved just prior to use in either the adjuvant or in Porcilis® PCV ID; an existing intradermal vaccine against porcine Circovirus type 2. In the two experimental vaccination-challenge studies, groups of 25 piglets were vaccinated once at 3 weeks of age or left unvaccinated as challenge control. Vaccines tested were Porcilis® Lawsonia ID as standalone (study 1) or in associated mixed use with Porcilis® PCV ID (study 2) and an orally administered commercially available live vaccine (study 1). The pigs were challenged with virulent L. intracellularis at 4 weeks (study 1) or 21 weeks (study 2) after vaccination. Post-challenge, the pigs were evaluated for clinical signs, average daily weight gain, shedding and macroscopic as well as microscopic immuno-histological ileum lesion scores. In the field study, the mortality and key performance parameters were evaluated over a period of 8 months. Results The results of the two experimental vaccination-challenge studies showed that Porcilis® Lawsonia ID as single vaccine or in associated mixed use with Porcilis® PCV ID, induced statistically significant protection against experimental L. intracellularis infection, 4 weeks or 21 weeks after vaccination. This was demonstrated by lower clinical scores, improved weight gain, reduction of L. intracellularis shedding and reduction of macroscopic as well as microscopic ileum lesion scores when compared to the controls. The protection induced was superior to that of the commercially available live vaccine. In the field study Porcilis® Lawsonia ID was highly efficacious in reducing L. intracellularis associated mortality and improving key production parameters. Conclusion The results support that this new intradermal vaccine is efficacious against L. intracellularis and may be used in associated mixed use with Porcilis® PCV ID.

Insufficient sleep is a strong risk factor for unhealthy weight gain in children. Māori (the indigenous population of Aotearoa (New Zealand)) children have an increased risk of unhealthy weight gain compared to New Zealand European children. Interventions around sleep could provide an avenue for improving health and limiting excessive weight gain with other meaningful benefits for whānau (extended family) well-being. However, current messages promoting good sleep may not be realistic for many Māori whānau. Using qualitative methods, the Moe Kitenga project explored the diverse realities of sleep in 14 Māori whānau. We conclude that for infant sleep interventions to prevent obesity and improve health outcomes for Māori children, they must take into account the often pressing social circumstances of many Māori whānau that are a barrier to adopting infant sleep recommendations, otherwise sleep interventions could create yet another oppressive standard that whānau fail to live up to.

The concern of people about nutritional quality and healthy eating make them to reduce meat consumption due to the fear of hypercholesterolemia. Against this background, there is need to incorporate cholesterol-reducing feed stuff into diets of meat producing animals. This study was therefore carried out to evaluate the performance as well as carcass quality of rabbits fed diets containing processed Mucuna seed meal (MSM) for 84 days. A total of 45 rabbit bucks (New Zealand White) of six weeks old were divided into three treatment groups of 15 rabbits each. Each treatment group was replicated thrice with five rabbits per replicate. The rabbit groups were randomly assigned to three treatment diets in a completely randomized design: The three experimental diets were formulated such that Mucuna pruriens seed (processed by soaking and boiling) replaced maize at 0, 20 and 30% as T1, T2 and T3 respectively. T1 served as the control without Mucuna Pruriens. Data were collected on feed intake, weight gain, feed conversion ratio, carcass traits and meat lipid profile viz: total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and high density lipoprotein (HDL). Result obtained revealed that rabbits on mucuna-based diets (T2 and T3) had significant (P<0.05) increase in feed intake and weight gain than rabbits on diet T1 (control). Similarly, carcass characteristics of the animals fed mucuna-based diets showed significant (P<0.05) increase in dressed weight, dressing percentage, cut parts (fore leg, hind leg, loin, thoracic cage) except organ (liver, kidney. heart, lungs) weights which were comparable to rabbits fed control diet. Significant (P<0.05) improvement in meat quality in terms of increase in HDL, protein, muscle, meat to bone ratio and reduction in TC, TG, LDL, VLDL and fat were obtained for the rabbit fed the mucuna-based diets. Economy of production indicated that cost of feed consumed and cost per weight gain reduced for rabbits fed MSM compared to those fed control diet. The results of the trial have shown that processed MSM can be used to substitute maize in diet up to 30% for improved performance, carcass traits and meat quality of rabbit bucks.     Les préoccupations des gens au sujet de la qualité nutritionnelle et d'une alimentation saine les font réduire la consommation de viande en raison de la crainte de l'hypercholestérolémie. Dans ce contexte, il est nécessaire d'incorporer des aliments pour animaux réducteurs de cholestérol dans les régimes alimentaires des animaux producteurs de viande. Cette étude a donc été réalisée pour évaluer la performance ainsi que la qualité de carcasse des lapins nourris à des régimes contenant des farines de graines de Mucuna transformées (le 'MSM') pendant 84 jours. Un total de 45 mâles de lapin (New Zealand White) de six semaines ont été divisés en trois groupes de traitement de 15 lapins chacun. Chaque groupe de traitement a été répliqué trois fois avec cinq lapins par réplique. Les groupes de lapins ont été assignés au hasard à trois régimes de traitement dans une conception complètement randomisée : Les trois régimes expérimentaux ont été formulés de telle sorte que les graines pruriens de Mucuna (traitées par trempage et ébullition) ont remplacé le maïs à 0, 20 et 30% comme T1, T2 et T3 respectivement. T1 a servi de contrôle sans Mucuna Pruriens. Des données ont été recueillies sur la consommation d'aliments pour animaux, le gain de poids, le rapport de conversion des aliments pour animaux, les traits de carcasse et le profil lipidique de la viande viz : cholestérol total (le 'TC'), triglycéride (le 'TG'), lipoprotéine de basse densité (le 'LDL'), lipoprotéine de très faible densité (le 'VLDL') et lipoprotéine de haute densité (le 'HDL'). Le résultat obtenu a révélé que les lapins qui suivreaient un régime à base de mucuna (T2 et T3) avaient une augmentation significative (P<0.05) de la consommation d'aliments pour animaux et du gain de poids que les lapins au régime T1 (contrôle). De même, les caractéristiques de carcasse des animaux nourris à base de mucuna ont montré une augmentation significative (P<0.05) du poids habillé, du pourcentage d'habillage, des parties coupées (jambe avant, patte arrière, longe, cage thoracique) à l'exception des poids des organes (foie, rein, cœur, poumons) comparables aux lapins nourris au régime de contrôle. Une amélioration significative (P<0.05) de la qualité de la viande en termes d'augmentation de la HDL, des protéines, des muscles, du rapport viande/os et de la réduction du TC, du TG, du LDL, du VLDL et de la graisse a été obtenue pour le lapin nourri aux régimes à base de mucuna. L'économie de production a indiqué que le coût des aliments consommés et le coût par gain de poids réduit pour les lapins nourris aux 'MSM' par rapport à ceux nourris régime de contrôle. Les résultats de l'essai ont montré que les 'MSM' transformés peuvent être utilisés pour remplacer le maïs dans l'alimentation jusqu'à 30 % par une meilleure performance, des caractéristiques de carcasse et la qualité de la viande des mâles lapins.

Treatment with Panax ginseng has been reported to elicit various biological effects in both animal and human models. Among the reported effects on animal are protein synthesis and growth promoting ability. For a better understanding, the current experiment was conducted to evaluate the effect of oral administration of P. ginseng extracts (PGEs) on growth performance parameters of growing New Zealand White (NZW) rabbits. A total of 48 NZW male and female rabbits, with the average age of two months were used for the experiment, conducted in a Randomized Complete Block Design (RCBD). The rabbits were organized into 3 groups of 16 rabbits each (8 males and 8 females), on weight equalization basis and randomly assigned to 3 treatments: T1, T2 and T3, containing PGEs at 0.0, 200.0 and 400.0 mg/ml, respectively. Final body weight and total body weight gain of the male rabbits on T2 and T3 were significantly (p < 0.05) higher than those of male rabbits on T1, while feed conversion ratio for the male rabbits recorded a higher (p < 0.05) value in T1 than in T2 and T3, which were similar (p < 0.05). Trunk length and breast girth of the male rabbits were significantly (p < 0.05) higher in T3 than in T1 and T2. Feed intake pattern was similar among the male rabbits, but different between males and females. Significant (p < 0.05) differences were not observed in all parameters measured among female rabbits, but all experimental rabbits followed the same pattern of body weight gain. Oral administration of Panax ginseng extracts at 200 and 400 mg/ml levels enhanced feed conversion ratio in male NZW rabbits, thereby increasing body weight gain, trunk length and breast girth, while feed intake patterns slightly differed between the male and female growing rabbits.

Introduction: Weight gain during smoking cessation is a major concern. The relationship between smoking and weight is complex and not well understood. There is interest in substitution of nicotine with food.Aims: This study investigates whether the development of food addiction explains weight gain following a quit smoking attempt.Methods: This study was a subset of a larger study investigating smoking cessation in New Zealand. Participants were assessed on five visits over a 1-year period. Using validated instruments, measurements for smoking, weight, food intake, craving and food addiction were taken.Results: Among the 256 participants, 54.7% attended at least one follow-up. Food addiction prevalence at baseline was 0.8%. 14.5% were quit at early follow-up and 14.8% at late follow-up. Weight gain was found in abstainers compared to those still smoking. No increase in food addiction was detected.Conclusion: The development of food addiction does not play a prominent role in post quit weight gain. Further research is needed to elucidate the underlying weight gain mechanisms.
