The paper mulberry (Broussonetia papyrifera) leaf is rich in alkaloids and flavonoids, which has high medicinal and feeding value. We aimed to analyze the effects of B. papyrifera leaf extract on growth performance, antioxidant capacity, immune functions, and fecal microflora of weaned piglets. Thirty healthy, 28-day-old piglets were randomly assigned to three groups and fed with a basal diet supplemented with 0, 150, and 300 g/t B. papyrifera leaf extract for 42 days (control group, group I, and group II) separately. The result revealed that the final weight of piglets in group II was higher than the other groups, and the diarrhea rate in this group was 62.9% lower than in the control group. The feed conversion ratio in group I was significantly lower than the other two groups. Higher blood urine nitrogen concentration was noted in group II, higher glutathione peroxidase and catalase in group II, higher superoxide dismutase in the control group, and higher immune globulins (Ig) IgG, IgA, and IgM in group II. There was no significant difference in community richness and community diversity among the three groups of fecal samples. The relative level of Roseburia was higher in groups I and II, while Lactobacillus was higher in the control group. In conclusion, supplementation with B. papyrifera leaf extract at a certain dosage can increase growth performance and antioxidant capacity of weaned piglets, reduce the occurrence of diarrhea, enhance immune functions and disease resistance, and affect the composition of fecal microflora.

Abstract: Papaya leaves contain several antioxidants (flavonoid, tanin, and vitamin C) which have antiatherogenic effects that may inhibit the progression of an atherosclerotic lesion. One of the risk factors causing atherosclerosis is the consumption of food containing highly saturated fatty acids e.g. lard. Low density lipoproteins (LDL) accumulate within the intima and then are oxidized (LDL-ox). This LDL-ox is ingested by macrophages, resulting in foam-cell formation (early lesion of atherosclerosis). This study aimed to find out the histological features of the aorta of wistar rats having lard diets without the addition of the papaya leaf extract; having lard diets along with the papaya leaf extract; and having lard diets followed by papaya leaf extract. This was an experimental study on 16 wistar rats divided into 4 groups: group I without treatment (negative control group), group II lard diet for 14 days (positive control group), group III lard diet with papaya leaf extract for 14 days (treatment group I), and group IV lard diet for 14 days, and then followed by papaya leaf extract for 14 days (treatment group II). It was found that the aorta of group I showed adipose cells in the intima and media layers; group II and III showed foam cells in both layers; and group IV showed foam cells in fewer numbers than group II. Conclusion: The aorta histological features of wistar rats given lard diets for 14 days, with or without papaya leaf extract, showed foam cells in the intima and media layers. Papaya leaf extraxt added to lard diets had no effect on decreasing foam cells (no protective effect), meanwhile papaya leaf extract following lard diets showed a reduction of foam cells (therapeutic effect). Keywords: papaya leaf, lard dietary, foam cells, wistar rat.   Abstrak: Daun pepaya mengandung antioksidan (flavonoid, vitamin C) yang berefek anti-aterogenik, sehingga diharapkan dapat menghambat perkembangan lesi aterosklerosis. Salah satu faktor risiko penyebab aterosklerosis yaitu makanan yang berkandungan tinggi asam lemak jenuh, antara lain lemak babi. Konsumsi lemak jenuh berlebihan dapat mengganggu fungsi sel endotel, sehingga lipoprotein berdensitas rendah (LDL) dapat masuk dan menjadi LDL teroksidasi (LDL-oks). Makrofag menangkap LDL-oks dan menjadi sel busa (lesi dini aterosklerosis). Penelitian ini bertujuan untuk mengetahui gambaran histologik aorta tikus wistar dengan diet lemak babi tanpa pemberian ekstrak daun pepaya, diet lemak babi bersamaan pemberian ekstrak daun pepaya, dan setelah diet lemak babi dilanjutkan pemberian ekstrak daun pepaya. Penelitian ini bersifat eksperimental. Subyek penelitian terdiri dari 16 ekor tikus wistar yang dibagi menjadi empat kelompok: kelompok I tanpa perlakuan (kelompok kontrol negatif); kelompok II dengan diet lemak babi selama 14 hari (kelompok kontrol positif); kelompok III dengan diet lemak babi serta pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan I); dan kelompok IV dengan diet lemak babi selama 14 hari, dilanjutkan pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan II). Hasil penelitian memperlihatkan gambaran histologi aorta kelompok I tampak perlemakan; pada kelompok II terdapat sel-sel busa; pada kelompok III masih terdapat sel-sel busa; dan pada kelompok IV terdapat sel-sel busa, namun dalam jumlah yang lebih sedikit dibandingkan pada gambaran kelompok II. Simpulan: Tikus wistar dengan diet lemak babi selama 14 hari, baik dengan maupun tanpa ekstrak daun pepaya, memperlihatkan gambaran histologik adanya sel-sel busa pada tunika intima dan tunika media aorta. Pemberian ekstrak daun pepaya bersamaan dengan diet lemak babi tidak berefek menurunkan jumlah sel busa (tidak ada efek protektif) sedangkan pemberian ekstrak daun pepaya setelah diet lemak babi berefek mengurangi jumlah sel-sel busa yang terbentuk (efek terapi). Kata kunci: daun pepaya, diet lemak babi, sel-sel busa, tikus wistar.

This study aims to determine the effect of adding different proportions of Broussonetia papyrifera (BP)-fermented feed on Hu sheep. A total of 40 male Hu sheep (weighting 20.6 ± 2.20 kg) were collected and then divided into group I, II, III, and IV, with 0%, 5%, 10%, and 15% of BP-fermented feed to based diet, respectively. After the trial period of 10 and 50 d, the sheep were slaughtered by conventional methods for the chemical analyses. It showed that adding 10% fermented feed could significantly increase the growth performance of the Hu sheep. Adding the fermented feed can improve the protein level, main flavor amino acid content, and fatty acid in the muscle. Based on the headspace solid-phase microextraction and gas chromatography – mass spectrometry methods, a total of 125, 120, 119, and 117 kinds of volatile compounds were identified in group I, II, III, and IV, among which the relative content of the acid compound, ester compound, ketone compound, and aldehydes in group II, III, and IV were higher than that in control group, respectively. Addition of BP-fermented feed could significantly improve growth performance and meat quality of Hu sheep.

This study aims at establishing the effect of T. daniellii and A. cordifolia leaf extracts on the lipid profile of experimental rat models. A total of twenty five (25) adult male wistar rats were used for the study. The rats were divided into five groups of five rats each. Group I (normal control) was administered with 2ml/kg distilled water p.o. Group II was administered with 200mg/kg aqueous leaf extract of T. daniellii p.o. Group III was administered with 200mg/kg methanolic leaf extract of T. daniellii p.o. Group IV and V were administered with 200mg/kg aqueous and methanolic leaf extracts of A. cordifolia respectively. Administration of extracts lasted for 14 days after which animals were sacrificed and serum developed from blood samples was collected and used for analysis to evaluate the lipid profiles of experimental models using standard methods. Results obtained from the study show that the highest level of Low Density Lippoprotein (LDL) (31.21±0.04 mg/dL) was recorded on Group II and was not significantly different from the control group (33.20±0.10 mg/dL). However, for High Density Lipoprotein (HDL), the highest level was recorded on Group IV (48.14±0.08mg/dL). Similarly, this was not significantly different from the Control group (51.80±0.10mg/dL). Group II presented the highest level of Triacylglyceride (TG) (48.80±0.02mg/dL), which however, was considered not significantly different from the control group (51.17±0.08mg/dL). For Total Cholesterol (TC), highest level (64.64±0.49mg/dL) was recorded on Group II and value was not significantly different from that recorded on the normal control (63.83±0.10mg/dL). In conclusion, it can be deduced from this study that extracts of T. daniellii and A. cordifolia lacks the potential to alter the lipid profile of patients depending on them for one medicinal use or the other and may thus be considered potential candidates for drug development.

Background: Diazinon is a globally used pesticide. Morus nigra (Black Mulberry) possesses flavonoids and phenols, which act as antioxidants. The objective of this study was to determine the possible protective effects of Morus nigra leaf extract on Diazinon-induced hepatotoxicity in rats. Material and Method: It was an experimental study conducted in the Department of Anatomy, Postgraduate Medical Institute, Lahore. A total of 36 healthy male Wistar albino rats were divided into three groups with 12 rats in each group. Group I was the control group. Group II was treated with 60 mg/kg body weight (bw) Diazinon daily for 4 weeks through orogastric intubation. Group III was treated with Diazinon 60 mg/kg bw daily along with 350 mg/kg bw of Morus nigra extract daily for 4 weeks through orogastric intubation. Blood samples were collected through cardiac puncture, for estimation of alanine transaminase (ALT) and aspartate transaminase (AST) levels. Liver dissection was done, slides of the hepatic tissue were prepared and studied under light microscope. The histology of hepatocytes, portal lobule, portal vein and sinuosoids was observed. SPSS 20 was used for data analysis. One-way ANOVA followed by Tukey’s test was applied to establish difference among groups with P-value ≤0.05 considered as statistically significant. Results: Histology of Liver tissue in group I showed normal morphology while group II revealed hypertrophy and vacuolization of hepatocytes, congested central vein and sinusoids and presence of necrotic foci. These toxic effects were reversed by the co-administration of Diazinon with Morus nigra in group III which showed normal histology of the hepatic tissue. Similarly, Diazinon administration resulted in significant elevation of ALT and AST levels (P-value<0.05), while, Morus nigra resulted in a considerable decline in the levels of these enzymes (P-value <0.05). Conclusion: Morus nigra extract has hepatoprotective effects against liver toxicity induced by Diazinon.

This study investigated the effects of dietary supplementation with fermented Mao-tai lees (FML) on growth performance, plasma metabolites, and intestinal microbiota and metabolites of weaned piglets. A total of 128 Duroc×Landrace×Yorkshire piglets (28-days old) were randomly assigned to one of four groups, feeding a basal diet (control group), a basal diet supplemented with 2, 4 or 6% FML, respectively, for 42days. The results showed that dietary 4% FML supplementation had higher (p&lt;0.05) average daily gain (ADG) and plasma triglyceride concentration during days 1–14 of the trial than the other FML supplemented groups. In addition, dietary 2 and 4% FML supplementation increased (p&lt;0.05) the ADG during days 15–28 of the trial and plasma total protein concentration on day 42 of the trial compared with the 6% FML supplement. The plasma concentrations of arginine, ethanolamine, histidine, isoleucine, lysine, methionine, proline, taurine, threonine, and tyrosine were increased (p&lt;0.05) in the 4% FML group compared with the other three groups on day 14 of the trial. Dietary supplementation with 2–6% FML decreased (p&lt;0.05) the plasma urea nitrogen concentration on day 14 of the trial and the abundance of Escherichia coli in the colon, and dietary 2 and 4% FML supplementation decreased (p&lt;0.05) the abundance of sulfate-reducing bacteria compared with the control group. In the intestinal contents, a higher concentration of FML (6%) supplementation decreased (p&lt;0.05) the colonic acetate concentration compared with the control and 2% FML groups, while 4% FML supplementation increased (p&lt;0.05) the colonic cadaverine concentration compared with the other three groups. In conclusion, dietary 4% FML supplementation might contribute to the increased amino acids metabolism without affecting the growth performance of weaned piglets. Moreover, dietary 2 and 4% FML supplementation were also beneficial to intestinal health via decreasing the abundances of specific pathogens and increasing the concentrations of microbial metabolites in the gut, which provides the theoretical basis and data support for the application of FML in pigs.

This study aimed to determine the effect of bay [Syzygium polyanthum (Wight) Walp.] leaf extract to decrease the blood triglyceride level of white rats (Rattus norvegicus). This research was an laboratory experimental research with pre and post-test design with control group. This research used 30 Wistar white rats, with ±200 g body weight and the age of ±2 months, divided into 5 groups by a random sampling, six rats per group. Group I was a negative control, group II was a positive control, groups III, IV and V was treated with the bay leaf extract in the doses of I, II and III. All groups were fed of hyperkolemia, group II was treated by Gemfibrozil 20 mg/200 g BW/day, while groups III, IV and V were treated by the bay leaf extract with the doses of 0.18 g, 0.36 g and 0.72 g/200 g BW/day. The study was conducted for 35 days. On the 28th and 35th day, the blood of all rats was taken from orbital vein for blood triglyceride levels measured in pre-test and post-test. The data were statistically analyzed with One-Way ANOVA test and a post-hoc test. There were significant differences between pre-test and post-test in the levels of blood triglycerides of white rats (p<0.001), in which a post-hoc test results showed the comparison between negative control and Gemfibrozil was p<0.001, and the comparison between the groups of the bay leaf extract with Gemfibrozil was p>0.05, and the comparison of three doses of bay leaf extract was p>0.05. The provision of bay leaf extract could reduce the blood triglyceride levels of white rats significantly compared with the negative control, whereas the effects of three doses of bay leaf extract was comparable with the effects of Gemfibrozil.

The present study investigated the effects of dietary paper mulberry (Broussonetia Papyrifera, BP) on growth performance, muscle quality and muscle growth-related mRNA expressions of grass carp. Fish (initial weight: 50.0 ± 0.5 g) were fed diets supplemented with 0% (control diet), 5%, 10%, 15% and 20% BP for 8 weeks. The results showed that increasing levels of paper mulberry linearly and quadratically decreased the special gain rate (SGR) and increased the feed conversion rate (FCR) of grass carp (p < 0.05). Significantly positive quadratic trends were found between paper mulberry levels and muscle crude fat or crude protein of grass carp (p < 0.05). In comparison to the control diet, the 10%BP and 15%BP groups had significantly decreased muscle crude fat and increased crude protein (p < 0.05). The levels of paper mulberry resulted in a linear and quadratic increase in water loss of grass carp muscle (p < 0.05), and all groups with paper mulberry supplementation were significantly higher than the control group (p < 0.05). Significant positive linear and quadratic trends were found between the paper mulberry levels and muscle fiber diameter or density of grass carp (p < 0.05). In comparison to the control diet, the significant differences were found in the 15%BP and 20%BP groups (p < 0.05). The muscle adhesiveness and hardness linearly and quadratically increased with the increasing levels of paper mulberry (p < 0.05), and both of which increased significantly when the level of paper mulberry reached 10% (p < 0.05). In addition, the increase in paper mulberry linearly and quadratically improved the expressions of myoblast determination protein (MyoD), myogenin (MyoG), paired box protein 7 (Pax7) and myostatin 1 (MSTN1) (p < 0.05). When the supplementation of paper mulberry reached 15%, the expressions of all these mRNAs were significantly higher than those of the control group (p < 0.05). In summary, adding 5% paper mulberry did not affect the growth of grass carp. However, the supplementation of 10% paper mulberry could improve muscle quality through improving muscle hardness, reducing fat accumulation and muscle fiber diameter, at the cost of reducing growth performance.

The aim of this study was to evaluate the effect of zinc (Zn) supplementation in different commercial forms on the growth performance, health status, and Zn balance of weaners in field conditions. The animals were fed pre-starter (from the 28th to 47th day of life) and starter (from the 48th to 74th day of life) mixtures differing in Zn form and concentration. Group I was given ZnSO4 at 150 mg kg−1; Group II received pre-starter zinc oxide (ZnO) at 3000 mg kg−1 and starter at 150 mg kg−1; and Group III was given 150 mg kg−1 of zinc oxide nanoparticles (nZnO). We found that the average daily gain in Group I was significantly lower, compared to Groups II and III. A commonly accepted level of Zn (150 mg kg−1) as nZnO can be recommended, instead of therapeutic doses of Zn preparations with the same efficiency. Moreover, a lower level of Zn in the diet can prevent the excessive accumulation of this element in waste and, thus, reduce environmental damage.
