Eimeria species causes disease in goats associated with poor growth, diarrhoea and decrease in production, high morbidity and mortalities. The present study was conducted to analyse the haematological and biochemical parameters in response to natural coccidian infection in Barbari and Jamunapari goat breeds in semi-arid tropics. Methods: A total of 474 goats were examined; 96 goats were selected (48 Barbari and 48 Jamunapari) and divided on the basis of high (12 males and 12 females) and low (12 males and 12 females) oocyst per gram (OPG) counts of both Barbari and Jamunapari goats. The blood was aseptically collected from the jugular vein, using a 22-gauge needle for each animal separately in 5 ml blood for the haematological and biochemical estimations. Result: In haematological parameters of Barbari goats there were no significant (P greater than 0.05) differences in males and females. Although significantly higher values of RBC were observed in low OPG females, similar results were also observed in Hct, Mcv, Hb, MCH and MCHC. Whereas, in WBC, Lymphocyte, Monocyte and Granulocyte statistically had no significant (P greater than 0.05) differences among all the groups. In haematological parameters of Jamunapari goats no significant (P greater than 0.05) differences was seen in males and females of both the groups. The same group of Barbari goats were also selected for biochemical parameters and high OPG females had significantly (P less than 0.05) higher blood glucose values. The blood potassium concentration was found to be significantly (P less than 0.05) higher in low OPG males compared to high OPG males. The same group of Jamunapari goats were selected for biochemical parameters and ALT, total protein and globulin had significantly (P less than 0.05) higher values in high OPG females than others. A/G ratio had significantly (P less than 0.05) higher value observed in high OPG males.","PeriodicalId":13410,"journal":{"name":"Indian Journal of Animal Research","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140755341","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}

The collected foeti were divided into three age groups viz. early prenatal (up to 50 days) or G-I, mid prenatal (51-100 days) or G-II and late prenatal (101 to 150 days) or G-III. The heart samples of the sheep foeti were processed by routine paraffin technique and after section cutting, the slides were stained by routine Haematoxyline and Eosin stains, Masson’s trichrome stain, Verhoeff’s stain and Gomori’s stain for studying the detailed histological and histomorphometrical parameters. Result: It was revealed that the cells lining the endocardium and epicardium became elongated from flat shape with advancing age. The intercalated discs appeared continuous from broken lines with advancing age in the myocardium of cardiac wall in sheep foeti. The frequency of blood vessels, connective tissue fibres and connective tissue cells increased with age in the subendothelium, subepicardium, myocardium and epicardium in the sheep foeti. The average thickness of heart chambers, average diameter of the myocardiocytes and their nuclei in atrial and ventricular walls, papillary muscles, pectinate muscles and Purkinje fibre cells revealed an age dependent rise in sheep foeti of G-I to G-III.

Those dogs which are not responded to the medical management, with severe degenerative changes and osteoarthritis were selected for surgical management for total hip replacement. The femoral stems used in this study were small (4) and Medium (2). The size of the acetabular cup used ranges from 20 to 22 mm outer diameter. The bone cement used was polymethyl methacrylate (PMMA) low viscosity type bone cement (Simplex-P).

The causative agent, class II NDV strains are frequently virulent and are classified into at least 21 distinct genotypes with several sub-genotypes. The circulating strains of NDV from mainland India are identified as genotype XIII, whereas emergence of a new genotype XXII has been reported recently from North East Region of India. Methods: A total of 25 poultry farms comprising a total population of 2165 birds were studied for field outbreaks of ND. Detailed post-mortem examination was conducted on a total of 121 dead birds and field outbreaks were confirmed by the detection of the F gene in tissue samples by reverse transcription PCR. Deduced amino acid sequence analysis of fusion proteins and phylogenetic analysis based on complete F gene were carried out to understand the molecular epidemiology of the circulating NDV strains. Result: This study has confirmed severe NDV outbreaks in the vaccinated flock, from Mizoram state of India. The three isolates from the outbreaks revealed the presence of the multi-basic amino acid residues at the fusion protein cleavage site (112RRQKRF117) identified as characteristic of velogenic strain. The phylogenetic analysis based on the complete F gene has characterized the isolates belonging to newly identified genotype XXII and subgroup XXII.2.

The pseudopregnancy or false pregnancy or pseudocyesis is a syndrome which is characterized by the presence of signs of pregnancy in a non-pregnant animal. False lactation or nervous lactation are the terms which are used to refer pseudopregnancy as there is very low quantities of milk production is seen. This condition can be differentiated with true pregnancy by using hormones and by correlation of behavioral symptoms of pregnancy with hormonal profiles for confirmation of pregnancy in female tigers. Methods: Total seven animals were used in the experiment and was divided into three groups (G I, G II and G III). Group G I consist of 03 non-bred animals of less than 9 years of age, G II consisted of 03 non-bred animals of more than 9 years of age and G III was consisted of 03 animals after mating irrespective of their age. Faecal samples were collected non-invasively from enclosures weekly up to 14 weeks. Only fresh samples (deposited within 24 h) was chosen, urine puddles were aspirated from the floor. The extracted samples were then analysed for estimation of relaxin, progesterone and prostaglandin F2 alpha metabolite (PGFM) by enzyme linked immunosorbent assay (ELISA). Result: Relaxin the hormone for early detection of pregnancy in felines gives elevated concentration from 49 days after mating and attains a peak during parturition, whereas, no elevation or peak was observed in pseudopregnant animals. Progesterone, in true pregnancy remains elevated from 7th week onwards after mating, it gets dropped after 7th week with wide fluctuation in pseudopregnant animals.
