The influence of dietary replacement of soybean meal with high-tannin faba beans on gut-bone axis and metabolic response in broiler chickens

Abstract Faba bean (FB) seeds can be a good protein-energy component in animal feed. However, the presence of anti-nutritional substances is a negative feature of FB seeds. The aim of this study was to examine the influence of different levels of unprocessed FB seeds in feed on the gut-bone axis and metabolic profile in broilers. Ninety six, 1-day-old Ross 308 broiler chickens were randomly selected to one of the 3 dietary treatments (32 chickens in each, divided into 8 pens with 4 birds per each pen): the control group fed standard diet with soybean meal and without FB seeds, group I fed 8/15% (starter/grower) of high-tannin FB seeds, and group II fed 16/22% of high-tannin FB seeds. Bone mechanical examination, hematological and serum biochemical analysis as well histomorphometry of small intestine and liver tissue were performed. The intake of high-tannin FB seeds, irrespective of their amount, did not alter the bone geometric, mechanical and densitometric parameters nor influenced basal hematological parameters, however it resulted in: decreased serum concentration of total cholesterol and calcium; a reduced longitudinal myenteron of small intestine; increased mucosa and villus epithelium thickness, villus length, thickness and absorptive surface in duodenum; increased number of active crypts in jejunum; unchanged collagen area, intercellular space, and total cell number in the liver; decreased number of multinuclear hepatocyte cells. Moreover, the livers of birds fed the higher dose of high-tannin FB seeds had lymphocytic infiltrates in portal tracts and sinusoids. Feeding of unprocessed high-tannin FB seeds exerted an influence on the gastrointestinal tract by increased absorptive surface. In conclusion, the dietary inclusion of unprocessed high-tannin FB seeds had no negative effects on broiler growth, tibial bone mechanical properties and intestinal characteristics. Unprocessed high-tannin FB seeds may be used in broiler diets, but their dietary levels should not be higher than those discussed.

The objective of this study was to investigate the protective effects of pomegranate (Punica granatum) juice (PGJ) on oxidative damages in liver tissue and erythrocytes of rats intoxicated by sodium fluoride (NaF). Rats were randomly divided into two groups: group I received standard diet and group II received orally 1 mL of PGJ. After 5 weeks of pretreatment, each group was divided again into two subgroups and treated for another 3 weeks as follows: group I was subdivided into a control group and a group that was treated with 100 ppm of NaF (in drinking water); group II was subdivided into one group that was treated daily with both 100 ppm NaF and PGJ (1 mL orally) and one that received daily 1 mL of pomegranate juice. Exposure to NaF decreased hematological parameters, changed the total protein, albumin, bilirubin levels, and increased the activities of hepatic marker enzymes. We also noted an increase in lipid peroxidation contents, accompanied by a decrease of reduced glutathione levels. Antioxidant enzyme activities in both tissues were modified in the NaF group compared with the control group. However, the administration of PGJ juice caused an amelioration of the previous parameters. Our results indicated the potential effects of NaF to induce oxidative damage in tissues and the ability of PGJ to attenuate NaF-induced oxidative injury.

It was postulated that a phytobiotic preparation containing cinnamon oil and citric acid added to drinking water for chickens in a suitable amount and for a suitable time would beneficially modify the microbiota composition and morphology of the small intestine, thereby improving immunity and growth performance without inducing metabolic disorders. The aim of the study was to establish the dosage and time of administration of such a phytobiotic that would have the most beneficial effect on the intestinal histology and microbiota, production results, and immune and metabolic status of broiler chickens. The experiment was carried out on 980 one-day-old male chickens until the age of 42 days. The chickens were assigned to seven experimental groups of 140 birds each (seven replications of 20 individuals each). The control group (G-C) did not receive the phytobiotic. Groups CT-0.05, CT-0.1, and CT-0.25 received the phytobiotic in their drinking water in the amount of 0.05, 0.1, and 0.2 mL/L, respectively, at days 1–42 of life (continuous application, CT). The birds in groups PT-0.05, PT-0.5, and PT-0.25 received the phytobiotic in the same amounts, but only at days 1–7, 15–21, and 29–35 of life (periodic application, PT). Selected antioxidant and biochemical parameters were determined in the blood of the chickens, as well as parameters of immune status and redox status. The morphology of the intestinal epithelium, composition of the microbiome, and production parameters of chickens receiving the phytobiotic in their drinking water were determined as well. The addition of a phytobiotic containing cinnamon oil and citric acid to the drinking water of broiler chickens at a suitable dosage and for a suitable time can beneficially modify the microbiome composition and morphometry of the small intestine (total number of fungi p < 0.001, total number of aerobic bacteria p < 0.001; and total number of coliform bacteria p < 0.001 was decreased) improving the immunity and growth performance of the chickens (there occurred a villi lengthening p = 0.002 and crypts deepening p = 0.003). Among the three tested dosages (0.05, 0.1, and 0.25 mL/L of water) of the preparation containing cinnamon oil, the dosage of 0.25 mL/L of water administered for 42 days proved to be most beneficial. Chickens receiving the phytobiotic in the amount of 0.25 mL/L had better growth performance, which was linked to the beneficial effect of the preparation on the microbiome of the small intestine, metabolism (the HDL level p = 0.017 was increased; and a decreased level of total cholesterol (TC) p = 0.018 and nonesterified fatty acids (NEFA) p = 0.007, LDL p = 0.041, as well as triacylglycerols (TAG) p = 0.014), and immune (the level of lysozyme p = 0.041 was increased, as well as the percentage of phagocytic cells p = 0.034, phagocytosis index p = 0.038, and Ig-A level p = 0.031) and antioxidant system (the level of LOOH p < 0.001, MDA p = 0.002, and the activity of Catalase (CAT) p < 0.001 were decreased, but the level of ferric reducing ability of plasma (FRAP) p = 0.029, glutathione p = 0.045 and vitamin C p = 0.021 were increased).

In diabetes mellitus, non-alcoholic fatty liver disease (NAFLD) is closely linked to hyperglycemia metabolism. This study aimed to find out how a banana peel supplemented diet affected histological and liver function changes in streptozotocin-induced diabetic rats. Vitamins, minerals, dietary fiber, antioxidants, and tryptophan are all contained in banana peel flour (BPF). Serotonin is a neurotransmitter that has been linked to depression and anxiety. This post-test-only control group study was conducted on twenty-five male Wistar rats which were separated into five groups with different treatments. Groups II to V were diabetic rats model groups that consumed standard diet mixed with BPF 0%, 5%, 10%, and 20%, respectively, while group I was a healthy control group fed a standard diet. Hepatic enzyme transaminase (Alanine Aminotransferase-ALT and Aspartate Aminotransferase - AST) and Hematoxylin-Eosin (HE) staining were analyzed with the NAFLD score to examine the liver function and hepatocellular morphology. A change in liver function was observed, as well as a substantial change in the levels of ALT and AST. The NAFLD score with HE staining showed substantial improvements in liver morphology, which was better seen at a 20% BPF dose. The current study supported the hypothesis that BPF had a hepatoprotective effect in diabetic rats, which may be due to the mechanism of controlling the hepatic enzyme transaminase and inducing liver regeneration.

Background: An in-depth study of dismetabolic mechanisms in the genesis of pre-eclampsia (PE) has been updated because pregnancy is considered as a natural model of metabolic syndrome (MS), as well as the metabolic disorders are important in development of essential hypertension.Aims: to reveal clinical and laboratory parallels in pregnancy complicated by PE without MS and pregnancy proceeding on the background of MS to assess the role of metabolic disturbances in the development of PE.Materials and methods: 82 women with MS were examined in the dynamics of pregnancy and were divided into 2 groups depending on the implementation of PE: group I consisted of 50 women with PE on the background of MS, group II 32 women with MS without PE. We formed group III consisting of 44 pregnant women with PE without accompanying diseases to assess the pathogenetic value of metabolic disorders in the development of PE. The IV (control) group consisted of 30 healthy women with physiological pregnancy. Metabolic, hematological parameters, hormones, markers of the proinflammatory state, endothelial hemostasiological dysfunction, decidualization and placental angiogenesis, accumulation dynamics and distribution loci of adipose tissue were determined in all pregnant women.Results: In the groups of pregnant women with PE, changes similar to MS were revealed: pronounced diabetic and atherogenic disorders with the development of pathological insulin resistance, hyperinsulinemia and leptinemia, endothelial-platelet link hyperactivation, thrombotic and inflammatory status, visceral type of fat deposition, hyperuricemia, hypersympathicotonia. It is proved that in the hierarchy of mechanisms of PE formation, placental dysfunction is a secondary alteration factor, which additionally potentiates the insulin resistance increase and the effects of structural and functional destabilization of the vascular endothelium.Conclusions: The direction of metabolic changes during pregnancy, the common development of PE and MS indicate the important role of dismetabolic mechanisms in the formation of PE.

The purpose of the study was to compare the effect of feeding broiler chickens with mixtures containing raw or extruded soybean seeds on the performance indices, slaughter value and liver histology of the animals. The research began with an analysis of the chemical composition of selected high protein feeds. A nutritional experiment was then performed on 108 sexed Ross 308 chickens, which were allocated to 3 equal groups (I, II, III). The chickens were reared for 42 days with ad libitum feeding. The birds from the control group (I) received mixtures in which the only high protein component was soybean meal extracted. Extruded soybeans and raw soybeans were fed to chickens in experimental groups II and III, respectively, in quantities that replaced 30% of soybean meal extract protein in the Starter mixture and 50% of this protein in the Grower and Finisher mixtures. During the experiment, the body weight of the birds (BW) and their feed intake (FI) were recorded. At the end of rearing, 12 chicks of body weights representative of their group and sex were slaughtered in each group. The results of the slaughter analysis were used to calculate the percentage of muscles, skin with subcutaneous fat and abdominal fat in the carcass. The weights of selected internal organs were also determined, and then their proportion in the chilled carcass weight was determined. In addition, after slaughter, chicken livers were collected to assess the histological image. Raw soybean meal extrusion resulted in an increase in protein content and a decrease in crude fibre by about 10%. Quantities of individual amino acids in the analysed material were proportional to the protein content. The extrusion of full-fat soybean seeds reduced the content of trypsin inhibitors by more than a half (to 9 mg/g), but the least of these compounds (1.2 mg/g) was found in soybean meal extract. The tannin content of extruded soybeans was about one-third of that of extracted meal and less than one-fourth of that of raw soybean. It was shown that the chickens receiving extruded soybeans reached a weight similar to that of the control group, with similar FCRs for individual rearing periods, whereas the use of raw soybean significantly (P ≤ 0.01) decreased both parameters. In addition, group III had a significantly lower dressing percentage (P ≤ 0.05) and a higher proportion of abdominal fat (P ≤ 0.01) compared to the other groups. The introduction of extruded or raw soybeans into the mixtures increased (P ≤ 0.05) the proportion of total internal organs. The microscopic image revealed that all chickens had a similar, normal histological structure. The results of this study show a beneficial effect of raw soybean extrusion on the nutritional value of soybeans. Extruded soybeans can therefore be recommended as a partial substitute for protein (30% in Starter and 50% in Grower and Finisher) from soybean meal extract in chicken broiler mixtures. Raw soybeans should not be used in the above amounts, mainly because of the clearly worse rearing results....

Background: Nephrotoxicity is characterized by raised serum urea and creatinine levels and kidneys being one of the primary organs of drug concentration and excretion are vulnerable to many widely used marketed drugs, including anti-cancer drugs, antibiotics, immunosuppressants, and radio contrast agents, are nephrotoxic. Aim: To determine the nephroprotective effect of ethanolic extract of Carica papaya seeds in Aminoglycoside induced acute nephrotoxicity. Study design: Quasi Experimental study. Methodology: Thirty Sprague Dawley rats were sub divided into 3 groups i.e., I, II and III with 10 rats in each group. Group II and III were administered Aminoglycoside drug; Gentamycin in 80 mg/kg) via intraperitoneal route once daily for 5 consecutive days to induce acute nephrotoxicity. At day 6, nephrotoxicity was confirmed by measuring serum urea and creatinine. Ethanolic extract of Carica papaya seeds (1000 mg/kg) was started once daily through oral route in group III for 5 consecutive days to see the nephroprotective effects of seed extract after causing acute kidney injury. All animals were given standard diet pellets manufactured at NIH. Results: Mean serum urea and creatinine for Group I (Control Group) at day 0 were 24.90 mg/dL ± 1.633 and .750 mg/dL ± .0619 respectively. Mean serum urea and creatinine for Group II (Disease Control Group) was 81.00 mg/dL ± 1.247 and 1.980mg/dL ± .0467 at day 6th. This suggested induction of nephrotoxicity by Gentamycin. Mean serum urea and creatinine for Group III (Ethanolic Extract Treated Group) at 11 day was 72.40mg/dL± .991 and 1.680 mg/dL± .0467 after 5 days treatment with ethanolic extract of Carica papaya seeds. Conclusion: We concluded that ethanolic extract of Carica papaya seeds has significant nephroprotective effects on Aminoglycoside induced acute nephrotoxicity in rats.

Hepatotoxic chemicals damage liver cells primarily by producing reactive oxygen species. The decoction of the leaves ofTamarindus indicaL. is used for liver disorders. In this work we evaluated the hepatoprotective activity of a tablet formulation of this plant. Thirty-five Sprague Dawley rats were randomly divided into five groups (n=7). First group (I) is control group, fed with standard diet. Groups II to V (hepatotoxic groups) were subjected to a subcutaneous injection of CCl4(0.5 mL/kg). Group II was negative control, fed with standard diet; group III was subjected to administration of Silymarin 150 mg/kg and groups IV and V were treated with tablets in dose of 100 mg/kg and 200 mg/kg, respectively. Lipid peroxidation and the activity of superoxide dismutase, catalase, and reduced glutathione were evaluated. Serum levels of alanine aminotransferase, aspartate aminotransferase, gamma-glutamine transferase, alkaline phosphatase, and a lipid profile were evaluated too. The tablets inhibit lipid peroxidation. The redox balance (SOD-CAT-GSH) remains normal in the experimental groups treated with tablets. The liver function using dose of 200 mg/kg of tablets was better than the other experimental groups. These results justify, scientifically, the ethnobotanical use of the leaves ofTamarindus indicaL.

The main objective of this experimental study was to determine how diets containing lupin meal affect the performance indicators, carcass value, and chemical composition of breast and thigh muscles in broiler chickens. The diets tested in experimental groups E1 and E2 differed as follows: in group E1, one third of nitrogen-containing substances (NSs) from extracted soybean meal was replaced with NSs from lupin meal; in group E2, two thirds were replaced compared to the control group. The replacement of soybean meal with lupin meal in experimental diets failed to produce any significant effect on the average live weight of chickens on Day 42 of the fattening period compared to the control group. The replacement of soybean meal with lupin meal resulted in decreased average weight of carcass and breast muscles and in decreased yield of breast muscles. Differences between the control group (C) and group E2 were significant (P &#x2AAC 0.01). Chickens in group E2 also showed a significant increase (P &#x2AAC 0.01) in the yield of the heart and stomach compared to the control group. The differences in weight and yield of thigh muscles between the control group and the experimental groups (E1 and E2) were not significantly affected. As far as chemical composition is concerned, chickens receiving the lupin-containing feed showed a significant (P &#x2AAC 0.01) increase in the ash content in breast muscles. On the contrary, in thigh muscles in group E2, the ash content decreased significantly (P &#x2AAC 0.01). The content of calcium showed an increasing trend in both breast and thigh muscles in both experimental groups. In contrast, the content of magnesium in chicken muscles in both experimental groups decreased. These differences were significant (P &#x2AAC 0.01) only in thigh muscles. Our results show that lupin seed is a suitable substitute for NSs contained in soybean extracted meal. It is considered optimal to replace up to one third of NSs contained in soybean meal with lupin seed. Higher inclusion rate of lupin meal in diets may reduce the growth intensity of chickens, particularly the yield of breast muscles. Due to substantial inter-varietal differences, it is necessary to optimize individual nutrients, particularly amino acids when formulating lupin-containing diets.

Abstract An experiment was conducted on 600 broiler chickens to determine the effect of using Camelina sativa oil as a dietary component on meat quality indicators. Broiler chickens were raised on litter under standard conditions of feeding and maintenance. In the second period of rearing, the control group (I) received a diet containing 6% rapeseed oil. Experimental groups were fed on a diet containing 3% rapeseed oil and 3% Camelina sativa oil (group II) and 6% camelina oil (group III). At the end of rearing 8 chickens from each group were slaughtered. A simplified analysis of the carcasses was conducted. Blood samples were taken to determine the content of total fat, triglycerides, total cholesterol and its fractions. Muscle samples were analysed for the content of dry matter, total protein and crude fat, fatty acid composition and malonic aldehyde (TBA). The meat was subjected to sensory evaluation. It was found that the introduction of Camelina sativa oil to the grower diet for broiler chickens does not have a negative effect on rearing parameters and carcass quality. What was observed was a tendency to reduce the proportion of abdominal fat in the carcass with increasing level of oil used in compound feed and increases in the total protein content of breast meat in group II receiving 3% of camelina oil. The addition of 6% of Camelina sativa oil to compound feed significantly decreased the content of total cholesterol and its fractions in the blood plasma of chickens in comparison to the other groups. The introduction of 3% and 6% of Camelina sativa oil to chicken diets enriched the breast meat in n-3 PUFA, mainly α-linolenic acid (ALA) and did not impair the flavour qualities of the cooked meat. The meat from chickens fed on a diet containing 6% of camelina oil was characterized by a greater increase of ALA.
