The objective of this study was to compare the molecular, physiological and microbial effects of mushroom powder (MP), vitamin D2 enriched mushroom powder (MPD2) and zinc oxide (ZnO) in pigs post-weaning. Pigs (four pigs/pen; 12 pens/treatment) were assigned to: (1) basal diet (control), (2) basal diet + ZnO, (3) basal diet + MP (2 g/kg feed) and (4) basal diet + MPD2 (2 g/kg feed). Zinc oxide supplementation improved the feed intake (p < 0.001); increased the caecal abundance of Lactobacillus (p < 0.05); increased the villus height (p < 0.05) in the duodenum, jejunum and ileum; increased the expression of chemokine interleukin 8 (CXCL8; p < 0.05); and decreased the expression of pro-inflammatory cytokine gene interleukin 6 (IL6; p < 0.05), tumour necrosis factor (TNF; p < 0.05), nutrient transporters peptide transporter 1 (SLC15A1; p < 0.05) and fatty acid binding protein 2 (FABP2; (p < 0.05) in the duodenum. Whereas dietary supplementation with MPD2 improved the gastrointestinal morphology (p < 0.05); increased the total volatile fatty acid concentrations (p < 0.05); increased the expression of anti-inflammatory cytokine gene interleukin 10 (IL10; p < 0.05) and nutrient transporters SLC15A1 (p < 0.05), FABP2 (p < 0.05) and vitamin D receptor (VDR; p < 0.05); and reduced the expression of pro-inflammatory cytokine gene IL6 (p < 0.05), it adversely affected average daily feed intake (ADFI; p < 0.001) and average daily gain (ADG; p < 0.05). Mushroom powder supplementation had a positive impact on gastrointestinal morphology (p < 0.05) and upregulated the expression of nutrient transporters SLC15A1 (p < 0.05) and FABP2 (p < 0.05) and tight junction claudin 1 (CLDN1) (p < 0.05) compared to the controls but had no effect on the expression of inflammatory markers (p > 0.05). Furthermore, MP reduced ADFI (p < 0.01); however, this did not negatively impact the ADG (p > 0.05). In conclusion, MP and MPD2 have limited use as commercial feed additives in replacing ZnO in pig diets as feed intake was reduced post-weaning.

Sorghum Grain

Sorghum grain was included in a basal diet of molasses (molasses 505, urea 21, sunflower meal 191, pangola grass hay 250, minerals 31 g/kg as fed) at rates of 0, 202, 391 and 707 g/kg, generating diets in which grain replaced 0 (diet A), 33 (diet B), 66 (diet C) and 100% (diet D) of the molasses and hay. The four diets were fed to groups of four Hereford steers (293–334 kg liveweight) over a 96-day period. One half of each treatment group was implanted with a growth promotant (zeranol), and all were slaughtered at a commercial abattoir at the end of the trial. The inclusion of 33% grain increased voluntary feed consumption, digestible dry matter (DM) intake (from 57·6 to 82·0 g digestible DM/kg0·75 per day and significantly increased liveweight gain from 592 to 900 g/day. Zeranol implantation also increased liveweight gain but not feed intake. Steers given only grain (diet D) had the highest liveweight gains (1127 g/day). The addition of grain to molasses diets decreased urinary N excretion and increased ammonia and volatile fatty acid (VFA) concentrations in rumen fluid. Molar proportions of propionic acid in total VFA increased from 0·15 to 0·20, and butyric acid decreased from 0·36 to 0·29 when 33% of the molasses was replaced by sorghum grain. The fat content (depth at sacral position) of the carcasses of steers given grain only (diet D) was significantly greater (14 mm) than that of steers given the basal diet of molasses (4 mm), and carcass fat contents were intermediate (10 and 11 mm) for steers given diets B and C respectively. It was concluded that the inclusion of small amounts of grain in molasses-based diets increased cattle growth principally by increasing digestible energy intake without decreasing molasses intake, thus improving the efficiency of utilization of molasses in molasses-based diets.

An experiment was carried out to determine the effects of dietary supplementation of Albizia lebbeck seed oil (ALO) on the fatty acid composition of weaner rabbits.50 weaned rabbits of mixed breed and sexes, aged between 6-7 weeks with an average initial body weight of 460 ± 1.3 were randomly assigned into five dietary treatments of ten rabbits per group; each group was further divided into 5 replicates consisting of two rabbits each. Basal diet was formulated to meet the nutritional requirements of rabbits according to NRC (1977). Rabbits in treatment 1, 2, 3, 4 and 5 were supplemented with ALO at 0 %, 0.1%, 0.2 %, 0.3 % and 0.4 % respectively. Feed and water was given ad libitum and the experiment lasted for 12 weeks.The results showed that significant differences (P<0.05) were observed in saturated fatty acid (SFA), polyunsaturated fatty acid (PUFA) and omega-6/omega -3 ratio (n-6:n-3) values obtained. Rabbits fed diet containing 0.4 % ALO had the highest PUFA value (54.17 %), followed by T4 (53.01 %), T3 (45.13 %), T2 (37.61 %) and T1 (26.93 %) respectively. Similarly (n-6:n-3) composition in T5 (3.65 %) increased in T5 fed 0.4 % ALO compared with T1 (1.38 %) fed 0% ALO.Antherogenic index were significantly (P<0.05) different among the treatments. It can be concluded that supplementation of ALO at 0.4 % highly influenced the composition of fatty acid in rabbit meat.

Abstract Background Intestinal health remains a key factor in animal production because it is essential for digestion, absorption and bacterial fermentation. Feed additives have been used to attenuate the weaning stress such as Zinc Oxide (ZnO) and benzoic acid (C7H6O2). The objective of this study was to evaluate the impact of of benzoic acid and probiotics (BA + P) on performance, diarrhea and cecal microbiota of piglets in the nursery phase (23 to 65 days). Results One hundred and sixty weaned piglets with an initial weight of 6.335 ± 0.698 kg and 23 days of age were submitted to four treatments: supplementation with 2500 ppm of Zinc oxide (ZnO), supplementation with a commercial blend of benzoic acid and probiotics (Bacillus licheniformis, Bacillus subtilis and Enterococcus faecium NCIMB 10415; Vevogut P®) (BA + P), supplementation with Zinc oxide plus benzoic acid and probiotics (ZnO + BA + P), and controls receiving only the basal diet without any supplementation. At 65 days of age, 32 piglets (n = 8 per treatment) were slaughtered for the evaluation of the cecal microbiota. Supplementation with ZnO and BA + P were associated with better feed conversion (P < 0.05) in the early stage (23 to 49 days) and with an improvement in all performance parameters over the entire experimental period. The occurrence of diarrhea was lower (P < 0.05) in the BA + P group. The 4 most abundant phyla along with unclassified bacteria represented 93% of all sequences. Firmicutes dominated the cecal microbiota of all groups, followed by Bacteroidetes. Richness represented by the observed number of genera and by the Chao index were statistically lower in ZnO and ZnO + BA + P supplemented animals compared to controls. The beta diversity analysis that compares similarities between bacterial communities demonstrated formation of two distinct clusters containing samples with and without supplementation with ZnO, confirming a strong influence of ZnO on the intestinal microbiota. Conclusion The use of Benzoic acid with probiotics yields similar performance results with lower impact on the gut microbiota compared to ZnO, and it should be considered as a potential alternative in swine production.

Dietary Preferences

Behavioural and genetic evidence shows that the taste system is intimately related to the sensing of nutrients with consequences for poultry nutrition practices. A better understanding of how chickens may sense fat could provide the background for selecting feedstuffs used in poultry feeds. Acid oils have the potential to be economical and sustainable feedstuffs. These fat by-products from the edible oil refining industry possess a similar fatty acid composition to the crude oils but are richer in free fatty acids (FFA). An experiment was conducted to study the effect of FFA content and the unsaturated:saturated ratio (U:S) on dietary preferences in hens. Four fat sources were added to a basal diet at an inclusion rate of 6%, determining the experimental diets: soybean oil (SO; high U:S, 5% FFA); soybean acid oil (SA; high U:S, 50% FFA); palm oil (PO; low U:S, 5% FFA); and palm fatty acid distillate (PFAD; low U:S, 50% FFA). The experimental diets were offered in a series of double-choice tests to forty-eight Lohmann Brown laying hens housed individually in cages. Each hen was offered the ten potential binary combinations of the four diets including each diet compared to itself (referred to as four control double-choices). Feed intake was measured for two hours twice a day after one hour of fasting. Consumption was analysed as a standard preference index (% of test diet intake in comparison with the total intake). Preference values were compared to the random choice value of 50% using the Student’s t-test. None of the four control comparisons differ significantly from 50% (p > 0.05), indicating that the changes in preference values observed in the other binary comparisons were related to the dietary changes associated to fat ingredients. Hens showed a feed preference for palm oil added diets over soybean oil diets (p < 0.05), with PO and PFAD being equally preferred (p < 0.05). However, in this trial the hens demonstrated a preference for SO (low %FFA) when offered in choice with SA (high %FFA) (p < 0.05). These results suggest that the degree of saturation plays an important role in dietary fat preferences: hens prefer predominantly saturated oils even when these are rich in FFA. Furthermore, when presented with a choice between predominantly unsaturated oils, hens prefer feed with a low %FFA. In conclusion, %FFA and the U:S ratio affected feed preferences in hens. The use of oils with greater preference values may give rise to greater feed palatability, enhancing feed intake at critical stages.

Twenty-five Hereford cattle, of both sexes and a mean liveweight (� s.e.) of 172 �5.6 kg were allocated randomly from stratified groups to five treatments in which urea (UR), urea plus maize (URM), urea plus maize flour and protected casein (URMFC) or protected casein alone (FC) were offered to individually penned cattle on a basal diet of native pasture hay (8.4 g N/kg dry matter (DM)) over 70 days. Rumen ammonia concentrations were low in cattle on the basal hay diet (mean � s.e.d.) of 17 � 10.0 mg N/L but were significantly increased (P<0.01) by a supplement of 280 g/head.day of protected casein (FC) to 70 mg N/L and increased further (1 68 mg N/L) when urea was included with maize (URM) in the treatment. Volatile fatty acid concentrations in rumen fluid were increased (P<0.05) only by URM which also resulted in higher (P< 0..01) molar proportions of propionic acid. All treatments increased (P< 0.01) the hay intake of cattle during the study with the exception of URM, which was based on a high rate of feeding (400 g/day) of maize flour. Liveweight change of cattle was increased (P<0.01) by urea (UR) and maize flour (URM) to 290 and 340 � 56 g/head.day respectively. Higher (P< 0.01) liveweight gains were recorded when protected casein was included in the diet (URMFC, FC), being 550 and 600 g/head.day respectively. The results are discussed in terms of the scope for improving the efficiency of gain in cattle on a low quality grass hay by including low rumen-degradable proteins as a supplement to grass hays.

The effect of zinc oxide (ZnO) and a Mycobacterium smegmatis-derived bio-response modifier (BRM) supplementation on blood neutrophil functions, high-mobility group box 1 (HMGB1) protein and pro-inflammatory cytokine responses was studied in early weanling piglets. In total, 45 piglets were placed in the following five groups: basal diet only (I), supplemented with ZnO (II), supplemented with BRM (III), supplemented with ZnO plus BRM (IV) in basal diet and basal diet without weaning from dam (V). The phagocytic activity, superoxide anion and myeloperoxidase production in blood neutrophils and the concentrations of HMGB1, TNF-α, IFN-γ and IL-1β in blood plasma were measured before and after weaning. The neutrophil functions were impaired and the concentrations of HMGB1, inflammatory cytokines, were elevated in piglets during the post-weaning period. The neutrophil functions were not improved until Day 7 of weaning (P &gt; 0.05) and pronounced elevation (P &lt; 0.05) in the concentration of pro-inflammatory cytokines and HMGB1 was observed until Days 14 and 21 respectively, in Groups II and III. The addition of BRM plus ZnO in basal diet improved superoxide anion and myeloperoxidase production on Day 2 (P &lt; 0.05) and decreased the TNF-α and IFN-γ concentrations on Day 7 (P &lt; 0.05), with no significant change in the level of IL-1β and HMGB1 in Group IV. Finally, it is concluded that addition of ZnO plus BRM in the diet induced the neutrophil functions and reduced the inflammatory cytokine response much earlier to stimulate innate immunity than did ZnO or BRM alone.
