Thirty male buffalo calves (284.40 ± 18.45 kg) were randomly distributed into three groups and fed a basal diet (BD) of concentrate feed mixture and roughages. The first group was fed BD and considered as the control, the second group was fed the BD supplemented with eubiotics at 1.0 kg/ton of concentrate, whereas the third group was intravenously infused with amino acid (IVAAI) injection at a dose of 2.0 ml/100 kg body weight. Results showed that the total gain and the average daily gain were improved (P < 0.05) with dietary eubiotics. The digestibility of some nutrients was increased (P < 0.05) with dietary addition of eubiotics. In addition, eubiotics stabilize (P < 0.05) the rumen pH, which reduce the risk of subacute ruminal acidosis but increased (P < 0.05) ruminal NH3-N and total volatile fatty acids. The rectal temperature was decreased (P < 0.05) with eubiotics supplementation. In conclusion, the use of eubiotics induced superior positive effects on the digestibility of nutrients, rumen fermentation, rumen enzymes, rumen protein concentration, growth performance, feed conversion, blood parameters and ameliorated the harmful effects of thermal stress of buffalo calves in comparison with intravenous infusion of amino acids.\u0000Key words: eubiotics; amino acids; buffalo calves; nutrient digestibility; rumen fermentation; growth performance","PeriodicalId":21765,"journal":{"name":"Slovenian Veterinary Research","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48643514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty baladi healthy dogs were included in the experimental study. Dogs were divided into four groups each group consisting of five animals; Group I (control group), the group that does not receive any medication. Meloxicam treated groups divided into: Group II which received meloxicam at a dose of 0.2 mg/kg BWT per OS /24 hr. Group III animals received the same previous dose of meloxicam and esomeprazole at a dose of 1mg/kg BWT per OS /24 hr. Group IV animals received the same dose of meloxicam and misoprostol 3μg /kg BWT per OS tid. Upon drug administration, dogs were kept under observation for 14 consecutive days. Clinical and hemato-biochemical analysis were evaluated across time (T0, T3, T7, T10 and T14). The image analysis of the gastroscopic examination was evaluated across time (T0, T7 and T14), endoscopic examinations were applied to all animals in four groups at three time points (T0, T7, and T14), endoscopic lesions were scored by use of a 5-point scale. Clinically, the most common clinical sings in dogs with Meloxicam induced- gastropathy were inappetence to anorexia, hematemesis, melena, abdominal pain and weakness, the specific endoscopic lesions of gastropathy were gastric erosion, hemorrhage and ulcers. Serum gastrin concentration is a biochemically sensitive indicator of gastropathy.

TAA administration significantly increases the hepatic cell enzymes (ALT, AST, ALP and GGT) in the serum referring to hepatic cell destruction with an increase in hepatic MDA with a reduction in GSH concentrations, antioxidant enzyme activities as well as down regulation of their expression levels. NAR administration either with or after TAA ameliorates this effect suggesting its antioxidant ability. In the fibrotic pathway, TAA treatment up-regulates the expression levels of fibrogenic biomarkers (TGF-β, collagen 1α and fibronectin) genes while NAR down-regulates these genes suggesting its anti-fibrotic ability. Histopathological analysis confirms the biochemical results.

Helminths affect the health and production of livestock which need to be controlled efficiently and economically. The high usage of anthelmintic drugs has increased anthelmintic resistance to all available classes resulting in failed treatment options and economic losses. Herbs, which may be better options for animal and food safety, are among the best candidates to control these parasites. For this purpose, a research experiment was conducted. Twelve Sahiwal heifers were used for the evaluation of the anthelmintic activity of herbal dewormers composed of various parts of local herbs. Animals were divided into 4 groups A, B, C and D, all the groups, except group D were given herbal dewormer powder. In an experiment of 30 days, doses were given on a weekly basis. Fecal samples for egg counts, blood and serum samples were obtained fortnightly and subjected to statistical analysis. Results revealed that the animals receiving herbal dewormer @ 1400 mg/Kg had the best results and egg counts and hematological values were significantly (P<0.05) better than the control animals.

On the other hand, Graviola is commonly used as a source of food and has a wide range of bioactive components. In this study, out of 50 albino rats, breast cancer was induced in 40 rats using 7,12-dimethylbenanthracene (DMBA). These rats were subjected to the treatment using Graviola leaves ethanolic extract (GLEE) and 5-Fluorouracil (5-FU) to evaluate the anti-carcinogenic activity and the immunohistochemical changes. A single oral dose of DMBA led to the induction of rats’ breast cancer. Induced mammary tumors were diagnosed, and all were malignant without any benign tumor. Among the malignant tumors, non-invasive, invasive, mixed (invasive and non-invasive), and unclassified malignant tumors were detected. The immunohistochemical analysis showed that estrogen and progesterone receptors revealed negative nuclear expression. However, HER2 receptors score was +3, and Ki-67 revealed 85-90% nuclear stainability, denoting a very high proliferative index. The morphometric analysis revealed that staining reactivities of HER2 and Ki-67 were 60.66 and 89.84%, respectively, and were significantly higher than ER (15.24 %) and PR (15.68%). Genetic studies revealed marked upregulation of P53 with GLEE more than 5-FU while Bcl2 showed down regulation with GLEE more than 5-FU. The quantitative analysis of GLEE phytochemical constituents showed the presence of some bioactive chemical compounds that exhibit many therapeutic activities.
