Background: For this study, information was gathered on 6785 Chokla sheep at the Central Sheep and Wool Research Institute in Bikaner, Rajasthan, India and documented between 1974 and 2020. Methods: (Co)variance components and genetic parameters of weight at birth (BW), weaning (WW), 6, 9 and 12 months of age (6W,9W and YW, respectively) of Chokla sheep, were estimated by average algorithm restricted maximum likelihood (AIREML), fitting six different animal models with various combinations of direct and maternal effects. Result: The direct heritability estimates increased from birth to twelve months of age and values for all the body weight traits except birth weight (0.170) were moderate (0.30-0.50). The maternal influence diminished as age increases and maternal genetic effect (m2) was found to be important and sizeable at weaning stage (0.181). Maternal permanent environmental variance was found to influence the early body weight traits. Negative and high estimate of covariance between direct and maternal effects, resulted in highly inflated values of additive heritability. In this condition, it is more useful to use the total heritability (h2t) for evaluation of the response for selection based on phenotypic values to prevent the use of biased estimates of additive heritability. Genetic and phenotypic correlations among body weights at different ages were positive and ranged from medium to high.

Background: Zoletil has been used at different dose rates with or without preanaesthetics through intramuscular or intravenous routes in canine patients with varying results in other countries. The doses recommended by the manufacturer as well as researchers and the observations on various clinico-physiological and hemodynamic parameters are also highly variable. Keeping these points in mind, the present study was conducted to study anesthetic/sedative effects of intramuscular administration of Zoletil (20 mg/kg) and also to study the effect of glycopyrrolate (0.005 mg/kg)-xylazine (0.5 mg/kg) supplementation on Zoletil (10 mg/kg)-induced total intramuscular anesthesia in dogs. Methods: Fourteen canine patients were divided into two groups, viz., A and B, with seven animals in each group.In group A, Zoletil (tiletamine-zolazepam) at the dose rate of 20 mg/kg body weight was administered intramuscularly as an anaesthetic. In group B, preanesthetic glycopyrrolate at 0.005 mg/kg body weight was administered intramuscularly. After 15 minutes, xylazine at 0.5 mg/kg body weight was administered intramuscularly. After 15 minutes of preanesthetic administration in the B group, anaesthesia was induced intramuscularly with tiletamine-zolazepam @ 10 mg/kg body weight. Result: Zoletil (Tiletamine-zolazepam, 20 mg/kg IM) (group A) is only recommended for non-surgical/diagnostic (viz. Gastro-intestinal endoscopy)/minor surgical procedures in uncooperative dogs. An intramuscular anaesthetic protocol using glycopyrrolate (0.005 mg/kg)-xylazine (0.5 mg/kg) - Zoletil (10 mg/kg IM) (group B) is recommended for major surgical procedures of long duration. Neither the anaesthetic protocol produced any serious deleterious effect on hemato-biochemical and hemodynamic parameters; hence both protocols can be used safely in dogs as per the requirements of the procedure.

Artificial oocytes were used of different mammalian species for repairing reproductive dysfunctions. Artificial oocytes are those created in vitro using enucleated germinal vesicle, metaphase I and metaphase II oocytes followed by embryonic cells, somatic cells, pluripotent stem cells and germ cells nuclear transfer. Artificial oocytes are under development, they have the potential to revolutionize reproduction in mammalian species. The potential applications of artificial oocytes include 1) treatment of infertility as premature ovarian failure, ovarian cancer, or other conditions that damage the ovaries, 2) preservation of fertility, 3) creating cloned and transgenic animals. While artificial oocytes have the potential to revolutionize reproductive medicine, there are still a number of challenges that need to be addressed before they can be effectively and safely used in humans including the adapting efficient and safe enucleation techniques. Furthermore, cellular reprogramming is the biggest obstacle for creating artificial oocytes in addition to activation procedures to ensure that artificial oocytes are genetically and epigenetically normal and producing healthy offspring. Several studies are designed to overcome these challenges and there is significant progresses being made. Offspring are obtained in several animals species whereas developed blastocysts were obtained in humans. This review is developed and implemented to discuss the progress in creation of “artificial oocytes” in addition to the factors affecting the developmental competence of reconstructed oocytes.

Background: Mitochondria are organelles called power plants of the cell, which are found in eukaryotic cells and are responsible for the production of energy needed by the cells through aerobic respiration. Mitochondrial dysfunction causes endocrinological, cardiovascular, metabolic and neurodegenerative diseases. The aim of this study was to examine the effects of body condition score (BCS), lactation, pregnancy, age and gender on Mitochondrial-Derived Peptide (MOTS-c) and Brain Mitochondrial Transporter Protein 1 (BMCP1) levels in Akkaraman sheep. Methods: Sheep are classified into 3 categories according to BCS (BCS less than 2, BCS=3-3.5, BCS≥4). In creating groups in terms of BCS, it was determined by the palpation method applied to the waist area. The sheep included in the study were divided into 4 groups: early lactation, early pregnancy, late pregnancy (dry period) and age (female and male sheep).1st group, ewes in the first period of pregnancy (on the 100th day of the first pregnancy) (n = 30), 2nd group, ewes in the early lactation period (n = 30), 3rd group, ewes in the dry period (the last two months of pregnancy) (n = 30) and in the 4th group, less than 2 (young) (n=30), 2-8 (adult) (n=30), 8 greater than (old) (n=30), male and female sheep (n=30) of different ages. =180) total of 270 animals. Blood samples were taken from the jugular vein of the sheep before the morning feeding. MOTSc and BMCP1 levels were determined in blood serum samples by ELISA method. Result: In the study, serum MOTS-c and BMCP1 levels in sheep during lactation and pregnancy were determined to be lowest in the VKS less than 2 group and highest in the VKS≥4 groups. Likewise, in age and gender groups, the highest level was detected in young lambs and yearlings in the VKS less than 2 group, while the highest level was detected in old sheep and rams in the VKS≥4 group. As a result, it was determined that different age, gender, pregnancy and lactation periods affected serum MOTS-c and BMCP1 levels depending on the change in BCS (P less than 0.05). It was concluded that MOTS-c and BMCP1 may be useful parameters in the evaluation of mitochondrial function, energy metabolism and metabolic profile.

Background: Smoking tobacco is a serious global health problem that is associated with psychiatric disorders and increased mortality rates. Nicotine, the main compound consumed during smoking, causes damage to different organs, especially the brain. The current study assessed the modulatory impact of Teucrium polium extract (TPE) on nicotine-induced behavioral and biochemical, alterations in mice brains. Methods: Twenty-four mice were divided into four groups and treated for three weeks. Group one was control, group two was subcutaneously injected with 2.5 mg/kg nicotine, group three received 100 mg/kg TPE orally, and group four was given 2.5 mg/kg of nicotine subcutaneously after an hour of oral administration of 100 mg/kg TPE. Result: The HPLC results of the plant extract showed the presence of 11 bioactive compounds. Nicotine administration increased anxiety and decreased locomotor activity and forelimb grip strength. Dopamine, serotonin, and acetylcholinesterase activity showed a significant decline in the nicotine-induced group. Treatment with TPE showed anxiolytic effects, modulated muscle strength and locomotor activity. Also, there was an increase in neurotransmitters compared with the nicotine group. In conclusion, TPE protected against nicotine-induced neurotoxicity through modulating behavior and neurotransmitter levels in mice.

Background: Caveolae are essential in regulating signal transduction mechanisms of ion channels in vascular tissue, including BKCa channels (maxi-K). The current study investigated the localization of maxi-K channels within caveolae. Methods: Sixteen rats were divided into two groups: A control group and a treated group, where arteries in the treated group were incubated with methyl-β-cyclodextrin (MβCD) to disassemble caveolae from artery tissue. Immunohistochemistry (IHC), immunocytochemistry (ICC), transmission electron microscopy (TEM) and Western blot techniques were used in this study. Result: IHC of intact arteries showed colocalization of maxi-K channels with caveolin-1 in smooth muscle and endothelial cells and colocalized of maxi-K channels with caveolin-3 in smooth muscle cells only. These findings were also corroborated with ICC in a single smooth muscle cell. TEM revealed caveolae covering most plasma membranes of smooth muscle and endothelial cells and showed that caveolae sit close to the sarcoplasmic reticulum only in smooth muscle cells. TEM showed incubating arteries with MβCD led to the disassembly of caveolae from artery tissue. This study concluded that maxi-K channels localize to caveolae and that caveolae abolishment by MβCD led to the abolition of the coupling of caveolae and the sarcoplasmic reticulum.

Background: The present study was undertaken to investigate protective activity of W. somnifera root extract (W.S.R.E.), cow urine (C.U.) and their combination against acetaminophen (APAP) induced toxicity in male mice. APAP also known as paracetamol, is a well-known drug used for its analgesic and antipyretic effects. However, outside of the therapeutic window, the toxicity may result. W.S. and C.U. are from indigenous sources of plant and animal origins, respectively with several therapeutic activities. Methods: Sixty adult swiss albino male mice were randomly divided into six groups, comprising of ten mice in each group. Group I (control group) received 2% gum acacia suspension for 14 days orally and on day 14, 0.9% NaCl (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents. Group II, III, IV, V and VI received 2% gum acacia, silymarin (@25 mg/kg b.wt.), W.S.R.E. (@100 mg/kg b.wt.), C.U. (@7.8 mL/kg b.wt.) and W.S.R.E. (@100 mg/kg b.wt.) and C.U. (@7.8 mL/kg b.wt.) co-treatment orally for 14 days and on day 14, APAP (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents as mentioned. On 15th day, the animals were sacrificed and samples were collected to study various hematobiochemical and growth related parameters. Result: The treatment of acetaminophen caused significant decrease in haemoglobin, total erythrocyte count whereas increase in total leucocyte and prothrombine time. There were significant (p£0.05) decreases in plasma total protein, albumin and globulin values in group II (APAP), as compared to control (group I). Treatment with W.S. +C.U attenuates these alterations. W.S.R.E., C.U. and their combination pre-treatment mildly restored the changes to normal observed following APAP exposure in mice. However, the results of co-treatment group were more pronounced as compared to individual treatment groups. Thus, it was concluded that treatment with W.S.R.E. and C.U. curtailed the toxic effect of APAP, however, co-administration of both potentiated the protective effect.

Jangir","doi":"10.18805/ijar.b-5162","DOIUrl":"https://doi.org/10.18805/ijar.b-5162","url":null,"abstract":"Background: The present study was undertaken to investigate protective activity of W. somnifera root extract (W.S.R.E.), cow urine (C.U.) and their combination against acetaminophen (APAP) induced toxicity in male mice. APAP also known as paracetamol, is a well-known drug used for its analgesic and antipyretic effects. However, outside of the therapeutic window, the toxicity may result. W.S. and C.U. are from indigenous sources of plant and animal origins, respectively with several therapeutic activities. Methods: Sixty adult swiss albino male mice were randomly divided into six groups, comprising of ten mice in each group. Group I (control group) received 2% gum acacia suspension for 14 days orally and on day 14, 0.9% NaCl (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents. Group II, III, IV, V and VI received 2% gum acacia, silymarin (@25 mg/kg b.wt.), W.S.R.E. (@100 mg/kg b.wt.), C.U. (@7.8 mL/kg b.wt.) and W.S.R.E. (@100 mg/kg b.wt.) and C.U. (@7.8 mL/kg b.wt.) co-treatment orally for 14 days and on day 14, APAP (@300 mg/kg b.wt.) intraperitoneally was administered after 30 min of prior treatment of various agents as mentioned. On 15th day, the animals were sacrificed and samples were collected to study various hematobiochemical and growth related parameters. Result: The treatment of acetaminophen caused significant decrease in haemoglobin, total erythrocyte count whereas increase in total leucocyte and prothrombine time. There were significant (p£0.05) decreases in plasma total protein, albumin and globulin values in group II (APAP), as compared to control (group I). Treatment with W.S. +C.U attenuates these alterations. W.S.R.E., C.U. and their combination pre-treatment mildly restored the changes to normal observed following APAP exposure in mice. However, the results of co-treatment group were more pronounced as compared to individual treatment groups. Thus, it was concluded that treatment with W.S.R.E. and C.U. curtailed the toxic effect of APAP, however, co-administration of both potentiated the protective effect.\u0000","PeriodicalId":507727,"journal":{"name":"Indian Journal of Animal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141105290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Infectious canine hepatitis (ICH) is an uncommonly recognized disease of dogs and wild canids. This study aimed to investigate and report an outbreak of infectious canine hepatitis (ICH) caused by canine adenovirus type 1 (CAV-1) in dhole (Cuon alpinus) pups at Bannerghatta Biological Park, Bengaluru, Karnataka. Methods: During this investigation, four dhole pups succumbed following a short clinical course of ICH. Clinical biochemical and hematological tests were done. Gross and histopathological observations were made along with genome detection through PCR. Result: Clinical findings comprised of leucopenia, thrombocytopenia and anaemia with high levels of total and direct bilirubin as well as ALT, AST and ALP enzymes. The necropsy findings were sub-mandibular edema, generalised icterus, petechial haemorrhages on liver, spleen, lungs, kidneys and skeletal muscles. Liver was enlarged, haemorrhagic, friable and severely icteric with rounded borders. Histopathologically, intranuclear inclusion bodies typical of CAV-1 infection could be observed in hepatocytes and Kupffer cells in the liver. The disease confirmation was done on histopathological findings and detection of CAV-1 genome through PCR.

Background: The use of synthetic bone substitute,b-tricalcium phosphate (β-TCP) as an osteo-conductive material and platelet-rich plasma (PRP) as an osteo-inductive material is the alternate strategies for replenishing bone loss. Thus, the present study was conducted to evaluate the bone healing efficacy of β-TCP and PRP combination in dogs with long bone fracture repaired with threaded intramedullary pinning. Methods: Fifteen dogs were selected, which were allotted to two groups irrespective of age, breed and sex. In six dogs of Group I intramedullary pinning was performed, while in nine dogs of Group II β-TCP and PRP was applied at fracture site after stabilising with intramedullary pin. Clinical and radiographic examinations were conducted preoperatively and postoperatively on 15th, 30th and 60th day. Result: The mean weight bearing and radiographic union scores were better in group II animals as compared to group I at different time intervals. The present findings suggest that β-TCP and PRP effectively enhances the bone healing in dogs with long bone fracture.
