Alfalfa Meal

Corn and soybean meal are the two main components in formula feed of farm animals, leading to a serious food competition between humans and livestock. An alternative may be to encourage the utilization of unconventional feedstuff in animal diet. In the current study, we evaluated the utilization of fermented alfalfa meal (FAM) in weaned pigs. Twenty weaned piglets (separately caged) were randomly divided into two groups. Pigs in the control group (CON) were fed corn-soybean meal diet, and part of corn and soya protein concentrate in the diet of another group was replaced by 8% FAM. After 40 days of feeding, the average feed intake of FAM pigs was increased (P > 0.05), and the villus height (VH) of jejunum and duodenum, crypt depth (CD), and VH/CD in FAM pigs was improved compared to the CON group (P < 0.05). The increase (P < 0.05) of goblet cells in the jejunum of FAM pigs was positively correlated with the expression of MUC-2 gene (R = 0.9150). The expression of genes related to immunity (IRAK4, NF-κB, and IL-10) and intestinal barrier (Occludin and MUC-2) in the jejunum, as well as the expression of ZO-1 and MUC-2 in the colon of these pigs, also showed increase (P < 0.05) compared to CON pigs, which was accompanied by the decrease (P < 0.05) of LPS concentration in the serum. The elevated proportion of CD3+ and CD8+ T-lymphocyte subsets in spleen (P < 0.05) confirmed the improvement of systemic immune function in FAM pigs. In addition, FAM pigs have a higher β-diversity of microbial community (P < 0.05) and promoted enrichment of probiotics such as Lactobacillus that positively was correlated with acetate concentration in the colon over CON pigs. In summary, partially replacement of expanded corn and soya protein concentrate with FAM (8%) may benefit the intestinal barrier and immune function of weaned pigs without affecting their growth. Our findings also provide evidence of the feasibility of FAM as a dietary component in pigs to reduce the consumption of grain.

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

Abstract Background: Seaweed-derived polysaccharides (SDP) represent an attractive source of prebiotic nutraceuticals for the food and animal husbandry industry. However, the mechanism by which SDP from Enteromorpha mediates pig growth are not fully understood. This study aimed to investigate how SDP supplementation influences the growth performance and intestinal health in weaned pigs.Results: In Exp. 1, 240 weaned pigs were randomly assigned to four dietary treatments and fed with a basal diet or a basal diet containing 200, 400 or 800 mg/kg SDP, respectively, in a 21-d trial. Pigs on the 400 or 800 mg/kg SDP-supplemented group had greater ADG and lower F/G ratio than those on the control group (P＜0.05). In Exp. 2, 20 male weaned pigs were randomly assigned to two treatments and fed with a basal diet (CON group) or a basal diet supplemented with 400 mg/kg SDP (the optimum does from Exp. 1), in a 21-d trial. Pigs fed the SDP diet had greater ADG, the concentrations of serum IL-6 and TNF-α and the activities of glutathione peroxidase, superoxide dismutase and catalase (P＜0.05), and lower F/G, diarrhea rate, as well as serum D-lactate concentrations and diamine oxidase activity (P＜0.05). Moreover, dietary SDP supplementation enhanced secretory immunoglobulin A content, villus height and villous height: crypt depth ratio in small intestine, as well as the lactase and maltase activities in jejunum mucosa (P＜0.05). SDP supplementation elevated the mRNA levels of inflammatory response-related genes (IL-6, TNF-α, TLR4, TLR6 and MyD88), and the mRNA and protein levels of ZO-1, Claudin-1 and Occludin in jejunum mucosa (P＜0.05). Importantly, SDP not only increased the Lactobacillus population but also reduced the Escherichia coli population in cecum (P＜0.05). Furthermore, SDP increased acetic acid and butyric acid concentrations in cecum (P＜0.05).Conclusions: These results not only suggest a beneficial effect of SDP on growth performance and intestinal barrier functions, but also offer potential mechanisms behind SDP-facilitated intestinal health in weaned pigs.

Processed fruit products commonly contain very low protein due to the heat treatment during processing period. This article presents the researchresults concerning the increase of nutrition value of papaya jam fortified with soya protein concentrate. Papaya jam prepared with ratio 40:1, 40:2, 40:3, 40:4, and 40:5 (v/v) of papaya pulp and soya protein concentrate. The treatment of papaya jam and soya protein with the highest acceptability was then analyzed for the changes in chemical constituents and overall acceptability at monthly interval during three months of storage. The parameters that being analyzed were moisture content, total soluble solids (TSS), pH, total and reducing sugars, non-enzymatic browning, acidity, ascorbic acid, total carotenoid, total phenol, crude protein, and total plate count.  The results showed that fortified papaya jams prepared with papaya pulp and soy protein concentrate ratio at 40:1 had the highest acceptability. During storage time it revealed that moisture content, TSS, pH, total and reducing sugars, and non-enzymatic browning increased, while acidity, ascorbic acid, total carotenoids, phenols, total antioxidants and crude protein contents of jam decreased. Fortification of papaya jam with soya protein concentrate (40:1 v/v) increased crude protein content on average from 3.15% to 4.16%. Total plate count (TPC) indicated that no microbial contamination during 3 months storage period. It can be concluded that papaya jam fortified with soya protein concentrate remained acceptable during storage although the acceptability decreased over time.

Casein-based diets containing a low (LDI) or high (HDI) dose of soya protein concentrate enriched with isoflavones were fed to obese Zucker rats for 6 weeks. HDI feeding, but not LDI feeding, reduced the fatty liver and decreased the plasma levels of alanine transaminase and aspartate transaminase. This was accompanied by increased activities of mitochondrial and peroxisomal β-oxidation, acetyl-CoA carboxylase, fatty acid synthase and glycerol-3-phosphate acyltransferase in liver and increased triacylglycerol level in plasma. The decreased fatty liver and the increased plasma triacylglycerol level appeared not to be caused by an increased secretion of VLDL, as HDI decreased the hepatic mRNA levels of apo B and arylacetamide deacetylase. However, the gene expression of VLDL receptor was markedly decreased in liver, but unchanged in epididymal white adipose tissue and skeletal muscle of rats fed HDI, indicating that the liver may be the key organ for the reduced clearance of triacylglycerol-rich lipoproteins from plasma after HDI feeding. The n−3/n−6, 20:4n-/8:2n−6 and (20:5n−3+22:6n−3)/18:3n−3 ratios were increased in liver triacylglycerol by HDI. The phospholipids in liver of rats fed HDI contained a low level of 20:4n−6 and a high level of 20:5n−3, favouring the production of anti-inflammatory eicosanoids. When obese Zucker rats were fed soya protein, this also resulted in reduced fatty liver, possibly through reduced clearance of VLDL by the liver. We conclude that the isoflavone-enriched soya concentrate as well as soya protein may be promising dietary supplements for treatment of non-alcoholic fatty liver.

Abstract The present study has investigated the potential of including different sources and levels of fiber (6.5% and 7.5%) in growing-fattening pigs’ diet. The nine weeks feeding trial was conducted on nine hybrids TOPIGS castrated males with an initial average weight of 25.25±2.11 kg, randomly assigned to 3 experimental groups with 3 replicates per group. The control group (C) was fed with a corn, wheat and soybean basal diet and it was characterized by 3.5% crude fiber (CF), the experimental groups E1 had 6.5% CF (4% alfalfa meal and 12.36 % sunflower meal) and E2 had 7.5% (6% alfalfa and 18.38% sunflower meal) decreasing the dietary rate inclusion of soybean meal from C (21.42% soybean meal). Bodyweight (initial, final), average daily feed intake (ADFI), leftovers were registered and average daily gain (ADG), feed conversion ratio (FCR) were calculated during the experiment. At the end of the study, the pigs were slaughtered for the determination of carcass traits and meat quality parameters. The productive performances were not influenced by the source or level of the fiber content. The saturated fatty acid (SFA) values were significantly different (P<0.05) in E1 group for shoulder and belly samples compared to C and for breast samples on E2. Higher MUFA concentrations significantly different (P<0.05) were noticed for ham, sirloin, rack, shoulder, breast on E1. PUFA, Ω:6 concentration shown significant differences (P<0.05) within E2 to all meat samples collected, except the neck. The best carcass classification results were recorded in the E1 with 6.5% cellulose (50% Class S and 50% Class E) according to the SEUROP system classification. The study concluded that the dietary percentages of alfalfa meal and sunflower meal did not compromise productive performances but the average muscle thickness and meat percentage registered lower values compared with group C. Further studies with the same raw materials but changing the inclusion percentages should have experimented with emphasis on carcass traits results.

Abstract β-Mannans are strongly anti-nutritive polysaccharide fibres found in most vegetable feed ingredients. The objective of the study was to compare piglet performance and antibiotic use between a Control group, fed a conventional 3-phase diet, and an Enzyme treated group, fed an adapted 3-phase diet including a β-mannanase enzyme (Hemicell™ HT; Elanco). A seven weeks feeding trial was conducted with 896 pigs in two rotations of 448 piglets in 32 replicate pens of 14 pigs. Two different 3-phase diets were compared: a standard 3-phase control diet and an adapted 3-phase diet including a β-mannanase enzyme included at 300 g/tonne. The following adaptations were made: Phase-1 (weeks 1–2): 1.14% potato protein concentrate and 1.00% Forcital (extruded soya product) were replaced with soybean meal. Phase-2 (weeks 3–4): 0.46% potato protein concentrate and 0.68% Forcital were replaced with soybean meal. Phase-3 (weeks 5–7): β-mannanase was formulated to replace 63 kcal/kg NE. Standard piglet performance parameters (ADWG, ADFI, FCR) and antibiotic use were recorded. All data analyses were performed using R version 3.6.3 (R Core Team, 2020). All tests were performed at the 5% level of significance. When multiple testing was involved, the nominal 5% Familywise Error Rate (FWER) was used. Throughout the trial and within each phase, ADWG, ADFI and FCR were not significantly different (P &gt; 0.05) between Control and Enzyme group. Mortality was significantly (P &lt; 0.001) lower (-0.90 %) in the Enzyme treated group. Antimicrobial use was significantly (P &lt; 0.01) lower (-56%) in the Enzyme treated group as compared to the Control group. Inclusion of a β-mannanase to nursery diets with an adapted formulation by replacing expensive protein sources by soybean meal, or reducing the NE content by 63 kcal/kg, resulted in similar piglet performance post-weaning with reduced mortality and less antimicrobials used.
