Marine Macroalga

In the present study, the effect of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions on daily amounts of feces and urine excreted by growing pigs, apparent fecal nutrient digestibility and daily nitrogen balance and retention, meat quality and the slaughter value of carcasses was examined. The duration of feeding experiments was 87 days. In the control group, the requirement for zinc and copper was covered by inorganic salts, whereas in the experimental group algae enriched with these elements via biosorption were supplemented. No effect of Enteromorpha sp. on the increase in digestibility of dry matter, dry organic matter, crude protein, crude fat and nitrogen-free extractives was observed. Statistically significant differences concerned only the digestibility of crude ash. The daily amount of excreted feces and urine did not differ significantly between groups. Meat from pigs in the algal group was characterized by a lower water absorption and drip loss and contained less fat and more protein than meat from the control group. Furthermore, a slight darkening of the meat was observed. The weight of the liver was lower in pigs from the algal group. Enriched macroalga Enteromorpha sp. may be introduced into pig nutrition as a feed material as an alternative to inorganic salts.

AbstractThe aim of the study was to perform feeding experiments on growing pigs in order to assess the impact of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions via the biosorption process on the mineral composition of blood, meat, liver, feces and urine. In the control group, microelements were supplemented as inorganic salts, whereas in the experimental groups they were replaced by enriched macroalga. After 3 months of the feeding experiment, it was found that the meat was biofortified with Cr, Mn, Fe, Cu and Zn. The average content of Zn in the blood from the pigs fed with algae was higher by 9.5%, compared to that in the blood from pigs in the control group. The liver of growing pigs from the experimental group contained 16% less Cu and 18% less Zn than the liver in the control group. Growing pigs fed with macroalgae excreted in feces 27% more Zn than growing pigs in the control group, but 3.5 times less Cu. It could be concluded that the bioavailability of microelements to pigs from algae was higher than from the inorganic salts. Baltic macroalgae enriched with microelement ions could be potentially used as a biological feed additive.

A total of 16 crossbred (Large White × Landrace) castrated male pigs averaging 30.0 ± 2.5 kg were used in two trials (2 × 8 pigs) to determine apparent nutrient digestibility. The control group received feed mixture consisting of wheat and barley. In the experimental group, 3% proportion of wheat was replaced by sodium humate. The results of nutrient digestibility showed significantly lower (P < 0.01) digestibility of crude protein (82.2 ± 1.92 vs. 87.9 ± 2.05%) and crude fat (32.0 ± 2.81 vs. 49.3 ± 2.25%) in the control group compared to the experimental group. Non-significantly lower digestibility was found in dry matter (86.0 ± 3.20 vs. 89.2 ± 3.08%), crude fibre (34.3 ± 3.64 vs. 37.6 ± 2.86%) and ash (56.1 ± 2.49 vs. 58.1 ± 2.47%). The results confirmed sorption ability of humate fed to pigs. The decrease of coefficients of apparent digestibility in nitrogen substances can lead to decreased amounts of ammonia into the environment of the stables.

Abstract Background Dietary fibers are widely considered to be beneficial to health as they produce nutrients through gut microbial fermentation while facilitating weight management and boosting gut health. To date, the gene expression profiles of the carbohydrate active enzymes (CAZymes) that respond to different types of fibers (raw potato starch, RPS; inulin, INU; pectin, PEC) in the gut microbes of pigs are not well understood. Therefore, we investigated the functional response of colonic microbiota to different dietary fibers in pigs through metatranscriptomic analysis. Results The results showed that the microbial composition and CAZyme structure of the three experimental groups changed significantly compared with the control group (CON). Based on a comparative analysis with the control diet, RPS increased the abundance of Parabacteroides, Ruminococcus, Faecalibacterium and Alloprevotella but decreased Sutterella; INU increased the relative abundance of Fusobacterium and Rhodococcus but decreased Bacillus; and PEC increased the relative abundance of the Streptococcus and Bacteroidetes groups but decreased Clostridium, Clostridioides, Intestinibacter, Gemmiger, Muribaculum and Vibrio. The gene expression of CAZymes GH8, GH14, GH24, GH38, GT14, GT31, GT77 and GT91 downregulated but that of GH77, GH97, GT3, GT10 and GT27 upregulated in the RPS diet group; the gene expression of AA4, AA7, GH14, GH15, GH24, GH26, GH27, GH38, GH101, GT26, GT27 and GT38 downregulated in the INU group; and the gene expression of PL4, AA1, GT32, GH18, GH37, GH101 and GH112 downregulated but that of CE14, AA3, AA12, GH5, GH102 and GH103 upregulated in the PEC group. Compared with the RPS and INU groups, the composition of colonic microbiota in the PEC group exhibited more diverse changes with the variation of CAZymes and Streptococcus as the main contributor to CBM61, which greatly promoted the digestion of pectin. Conclusion The results of this exploratory study provided a comprehensive overview of the effects of different fibers on nutrient digestibility, gut microbiota and CAZymes in pig colon, which will furnish new insights into the impacts of the use of dietary fibers on animal and human health.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

AbstractThe aim of this experiment was to examine the possibility of replacing part of soybean meal in the diets of sows, their piglets and fatteners with two varieties of high- or low-tannin faba bean seed. Twenty-four sows were allocated to 3 groups, 8 animals in each. Control group (C) received standard feed mixture containing soybean meal as the main protein source. Next groups received standard feed mixture in which part of soybean meal was replaced by high-tannin variety Bobas (group HT) or low-tannin variety Kasztelan (group LT). Faba bean was added to diets at the level of 12 and 14% for pregnant and lactating sows, 6% for piglets, and 12 and 16% for fatteners (grower and finisher, respectively). Diets for half piglets and fatteners were supplemented with the enzyme Ronozyme VP. Apparent digestibility of nutrients was evaluated in a parallel experiment, using the same feeds on 18 barrows weighing about 40 kg (grower) and 80 kg (finisher). There was almost no difference in sow reproductive rates, litter weight and body weight of piglets on the first day of life were similar. Until 35 days of age piglets receiving faba bean grew faster than control ones. Control piglets grew fastest from 35 to 84 days of age, but differences were not significant. Enzyme supplement had a positive effect on body weight only from 56 to 84 days of piglet life. Digestibility of nutrients was lower in pigs fed with faba beans, especially in the grower period. Faba bean HT had lower nutrient digestibility in both periods of fattening. Almost all carcass traits were better in control pigs than in those fed with bean variety Bobas. Meat of these pigs had also the lowest content of unsaturated fatty acids and highest atherogenic indices. In sensory evaluation this meat had also the worst smell and taste. It can be stated that faba bean seeds, in moderate amounts, can partially replace soybean meal in feed for pigs, but some lowering of body weight gain and meat quality is possible especially when high-tannin varieties are used.

Abstract As an alternative to antimicrobial growth promoters, fermented feed (FF) has been continuously developed for two decades; however, its effects on feed, performance, digestibility, and meat quality of pigs have yet to be systematically and comprehensively evaluated. This study aimed to (i) quantitatively evaluate the effects of fermentation on nutritional components of feed stuffs; (ii) quantitatively evaluate the effects of FF on pig growth performance, digestibility, and meat quality; and (iii) explore the dose–effect relationship. From PubMed and Web of Science (searched range from January 1, 2000 to April 4, 2019), we collected 3,271 articles, of which 30 articles (3,562 pigs) were included in our meta-analysis. Our analysis revealed that fermentation significantly increased the CP content in feed (P &lt; 0.05). For weaned piglets and growing pigs, FF significantly improved ADG, G:F, DM digestibility, N digestibility, and energy digestibility (P &lt; 0.05). However, compared with the basal diet, FF had no significant effects on growth performance and nutrient digestibility in finishing pigs (P &gt; 0.05). In the subgroup analyses, fermented ingredients increased the growth performance of weaned piglets and growing pigs, and fermented additives promoted the growth of pigs at all stages. The dose–effect analysis confirmed that the optimal doses of fermented ingredients and additives were 8% and 0.15%, respectively. Furthermore, FF had beneficial impacts on meat quality through increased lightness, redness, marbling and flavor and reduced drip loss (P &lt; 0.05). In conclusions, FF improved growth performance and meat quality primarily due to its positive effects on nutritive value and utilization.

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p < 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p > 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p < 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p < 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p < 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.

Aim: The experiment was conducted to evaluate the effect of swine-origin probiotic Pediococcus acidilactici FT28 on growth, nutrient utilization, health status, meat quality and intestinal morphology in growing female pigs. Materials and Methods: Pigs (n=27) were distributed into three groups (3 replicates of 3 each) and supplemented with basal diet either without probiotics (C) or with a probiotic of dairy-based (Lactobacillus acidophilus NCDC-15; TLact) or swine based (P. acidilactici FT28; TPedic). The probiotics were fed as fermented feed at 200 g/pig/day. At the end of the trial, six pigs from each group were selected for metabolism trial and then sacrificed to determine meat quality and intestinal morphology. Results: Supplementation of both probiotics improved growth performance, whereas feed intake, digestibility of CP and N retention were better (p<0.05) in P. acidilactici FT28-fed group. However , the digestibility of dry matter (DM), organic matter (OM), ether extracts (EE), crude fibre and nitrogen free extract did not show any significant effect on probiotic supplementation. The serum A: G ratio, triglyceride, and cholesterol level were also improved (p<0.05) in TPedic group compared to other treatment groups. Both probiotic supplementations showed lower (p<0.05) serum glucose level with similar protein and albumin value, which indicated good utilization of feed as well as health status of growing pigs. Dressing percentage, vital organ weight, and EE of loin meat were higher (p<0.05) in probiotic-supplemented groups compared to control. However, P. acidilactici FT28-fed animals showed higher (p<0.05) CP and total ash percentage of meat without affecting pH, water holding capacity, and extract release volume of loin muscle. The villi height and crypt depth were better in both supplemented groups compared to control. Conclusion: Results of the present study revealed that P. acidilactici FT28 could serve as better probiotic source in swine production for the better utilization of CP and N-retention in meat with improved health status and intestinal morphology.
