Squamous cell carcinoma is one of the muco-cutaneous soft tissue growths occurs in horses. Proliferative external genitalia squamous growth is a common type. This case report is about ulcerative squamous growth which is common in eyeball but uncommon in prepuce area. A Marwari 11 year old stallion was presented to the Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of mass in the external genitalia which had increased in size gradually over 12 months with ulceration shown in the last 5 weeks of that period. On clinical examination, ulcerated mass was noticed in the prepuce. Pudental nerve block was done for physical examination. Fine needle aspiration cytology and impression smear didn’t reveal tumour pathology. The presented case was tentatively diagnosed as preputial tumour and planned to perform surgical excision. Under xylazine and ketamine anaesthesia and triple drip maintenance, the preputial tumour mass was excised and samples were sent for histopathology which revealed poorly differentiated squamous cell carcinoma. Post-operative antibiotics, painkillers were administered and wound dressing done for 5 days. Animal had an uneventful recovery without recurrence.

Background: Microsatellites are short repeat motifs consisting 1-6 base pair (bp) and have a high degree of length polymorphism and are useful to study the genetic diversity. In Chicken, no micro satellite markers were demarcated to different chromosomes, viz., 29, 34, 35, 36, 37, 38 and 39 in the genome. In the present study, we carried out chromosome-wise identification of SSRs that will be of great use in diversity and gene mapping studies in chicken. Methods: The perl script of MISA tool was used to screen the polymorphic microsatellites with different thresholds level. Result: We identified a total of 397877 SSRs from the latest chicken genome assembly (GRCg7b), of which mononucleotides, dinucleotides, trinucleotides, tetranucleotides, pentanucleotides and hexanucleotides composed of 307453 (77.27%), 40991 (10.30%), 23059 (5.79%), 16723 (4.20%), 8127 (2.04%) and 1524 (0.38%), respectively.

Background: Reproductive management of goats on large scale becomes difficult due to contributing reasons like poor estrus expression, lack of heat detection techniques, etc. Synchronization of ovulation has significantly improved the conception in cows. However, such investigations are lacking in goats. Hence, an experiment was conducted to compare the efficacy of different ovulation synchronization protocols on kidding and fecundity rates in Tellicherry goats during winter and summer seasons. Methods: The study was conducted in 240 does of 60 days postpartum period in two different seasons and investigated the efficacy of different protocols, The efficacy of intravaginal sponge (group I), Ovsynch (group II), Ovsynch with sponge (group III), Co synch (group IV), Co synch with sponge (group V) and control (group VI) on kidding and fecundity rate following fixed time breeding (NS/AI) was investigated in Tellicherry goats. Result: The overall kidding rate recorded during winter season in natural service (NS) was 80.00 and Artificial Insemination (AI) it was 70.00 per cent and in summer season it was 60.00 and 55.00 per cent, respectively. During winter season the fecundity rates observed were 1.70, 1.60, 1.75, 1.60, 1.60 and 1.40 in group I, II, III, IV, V and VI, respectively. The corresponding values during summer season were 1.55, 1.40, 1.60, 1.45, 1.50 and 1.10, respectively. From this study, the ovsynch with intravaginal sponge protocol found to be an effective protocol for ovulation synchronization in Tellicherry goats.

Background: Physical activity alters the cardiovascular system of dogs depending on the exercise characteristics and the animal’s physical conditioning. Little is known about the cardiovascular changes in working police dogs. This study evaluated the cardiovascular responses of working Labradors to regular exercise and various workload. Methods: Twelve working Labradors of Tamil Nadu police department that were regularly trained and exercised 30 minutes morning and evening and twelve normal household pet Labradors brought for regular checkup to Madras Veterinary College Teaching hospital were taken for the study. All the animals were subjected to physical, clinical, hematobiochemical, electrocardiographic examinations and cardiac auscultation before performing echocardiography. Those animals which showed normal recordings in all the above tests were further subjected to M-mode, Pulsed wave and Tissue Doppler echocardiography. In this study, the resting heart rate values of working groups were lesser than that of normal pet dogs. Result: The results of echocardiography showed significant increase in Interventricular septal diameter during diastole, left atrial diameter, aortic artery diameter and the left atrium to aortic diameter ratio without impairing systolic and diastolic cardiac functions in working dogs. The present study indicated that there were few changes in the echocardiographic parameters which might be a response to physiological adaptation and regular exercise.
背景：运动会改变狗的心血管系统，这取决于运动特点和动物的身体状况。人们对工作警犬的心血管变化知之甚少。本研究评估了工作用拉布拉多犬对定期运动和各种工作量的心血管反应。研究方法本研究选取了泰米尔纳德邦警察局的 12 只工作用拉布拉多犬和 12 只普通家庭宠物拉布拉多犬作为研究对象，前者定期接受训练并早晚锻炼 30 分钟，后者则定期到马德拉斯兽医学院教学医院接受检查。在进行超声心动图检查前，对所有动物进行了体格、临床、血液生化、心电图检查和心脏听诊。在所有上述检查中均显示正常的动物将进一步接受 M 型、脉冲波和组织多普勒超声心动图检查。在这项研究中，工作犬组的静息心率值低于正常宠物犬。结果超声心动图结果显示，工作犬舒张期室间隔直径、左心房直径、主动脉直径和左心房与主动脉直径比值明显增大，但不影响心脏收缩和舒张功能。本研究表明，超声心动图参数变化不大，这可能是对生理适应和定期运动的反应。

Background: The use of alternate feed resources like tree leaves is key element in addressing the problems derived from climate change and food shortages that demand establishment of sustainable feeding system for ruminants. Methods: A study was conducted on 36 Nellore cross ram lambs (6-7 months; 18.48±0.29 kg BW) randomly allotted to six dietary treatments to evaluate the effect of 20% dietary inclusion of moringa (MOR) subabul (SBL) and guava (GVL) leaves either sole or in combination (MS and MG mixture incorporated at 60:40 and 40:60, respectively) in concentrate mixture on nutrient utilization, plane of nutrition and nitrogen balance. The control group concentrate mixture contained maize, de-oiled rice bran, cotton seed cake and soybean meal as major ingredients and in the 5 experimental concentrate mixtures, de-oiled rice bran and soybean meal were partially replaced with moringa (MOR20), subabul (SBL20), guava (GVL20), moringa and subabul mixture (MS20) and moringa and guava mixture (MG20), by including them at 20%. Animals were fed with respective concentrate mixtures to meet about 80% of protein requirements and sorghum stover was offered ad libitum to meet the nutrient requirements of lambs for maintenance and growth as per ICAR (2013). Result: Dietary inclusion of tree leaves had no effect on the intake of various nutrients viz. DM, OM, CP, EE, CF, NFE, NDF,ADF, Hemicellulose and cellulose and were comparable (P greater than 0.05) among the six dietary groups. The crude protein and crude fibre digestibility improved (P less than 0.01) in tree leaves included diets compared to control, while ether extract (EE) digestibility was lower (P less than 0.01) in tree leaves included diets compared to CON. The DCP, TDN (%) and ME content was higher (P less than 0.05) in MS20, MG20 and MOR20 groups compared to CON. The N intake (g/d), excretion through faeces and urine (g/d), total N excretion and total N balance (g/d) was comparable among the different dietary groups.

Zearalenone (ZEN) is a mycotoxin that is usually found in moldy grains. ZEN causes reproductive toxicity to domestic animals by interfering with follicular and embryonic development, reducing sperm vitalityand destroying the homeostasis of endogenous hormones, leading to reproductive system diseases such as abortion, ovarian dysfunctionand stillbirth. The reproductive damage caused by zearalenone is mainly attributed to the factors as follows: (1) interaction with estrogen receptor; (2) induction of oxidative stress; (3) induction of apoptosis, necrosis, autophagyand iron prolapse and (4) interference with cell replication cycle. Natural compounds and micro-nutrients have the potential to alleviate the oxidative stress caused by ZEN. In addition, some microorganisms and enzymes have also shown good detoxification effects. Therefore, in this review, we focus on the damage caused by ZEN on animal gamete development and embryonic development, its molecular mechanismsand suggested some potential mitigation measures for the prevention of ZEN-induced toxicity to provide information for preventing toxicity associated with ZEN as well as serve as a foundation for further development of drug candidates for the treatment of ZEN induced damage.
玉米赤霉烯酮（ZEN）是一种霉菌毒素，通常存在于发霉的谷物中。玉米赤霉烯酮通过干扰卵泡和胚胎发育、降低精子活力和破坏内源性激素的平衡，对家畜造成生殖毒性，导致流产、卵巢功能障碍和死胎等生殖系统疾病。玉米赤霉烯酮对生殖系统的损害主要归因于以下因素：(1）与雌激素受体相互作用；（2）诱导氧化应激；（3）诱导细胞凋亡、坏死、自噬和铁脱落；（4）干扰细胞复制周期。天然化合物和微量营养素有可能减轻 ZEN 造成的氧化应激。此外，一些微生物和酶也显示出良好的解毒效果。因此，在这篇综述中，我们重点探讨了 ZEN 对动物配子发育和胚胎发育造成的损害、其分子机制，并提出了一些预防 ZEN 引起的毒性的潜在缓解措施，从而为预防与 ZEN 相关的毒性提供信息，并为进一步开发治疗 ZEN 引起的损害的候选药物奠定基础。

Background: The study investigated the effective roasting or sprouting of cowpeas (Vigna unguiculata) based on effects on in vitro digestibility (IVDMD), supported by measurement of key chemical components and trypsin inhibitor activity (TIA). Methods: The in vitro dry matter digestibility (IVDMD) of raw and all processed cowpeas were evaluated using standard, 3-step (gastric-ileal-colon) simulation of porcine digestion, modified for micro (0.5 g) sample digestion. Standard methods were employed to track processing effects on Ash, CP, Fat, ADF, NDF and trypsin inhibitor activity (TIA) at key processing points. Result: Sprouting for 2 and 3 days significantly decreased (p less than 0.05) gastric-ileal IVDMD while increasing (p less than 0.05) colon IVDMD. Total (steps 1-3) IVDMD increased (p less than 0.05) in 2-day (0.911) and 4-day (0.902) sprouts. The 20-minute cowpea roasting to 105°C terminal grain temperature resulted in high (p less than 0.05) step 3 and total IVDMD coefficients. The lowest (p greater than 0.05) total IVDMD was recorded in 15-minute (0.883) (95°C terminal grain temperature) roasts. In both experiments 1 and 2, quantitative changes in IVDMD were consistent with the changes in the chemical components (ADF, NDF, fat, CP, minerals) and trypsin inhibitor activity. In conclusion, the compartmental and total IVDMD and quantitative change in chemical components and TIA indicated 4 days sprouting and 20-minute (105°C) roasting were respectively most effective for cowpea processing.

Standard methods were employed to track processing effects on Ash, CP, Fat, ADF, NDF and trypsin inhibitor activity (TIA) at key processing points. Result: Sprouting for 2 and 3 days significantly decreased (p less than 0.05) gastric-ileal IVDMD while increasing (p less than 0.05) colon IVDMD. Total (steps 1-3) IVDMD increased (p less than 0.05) in 2-day (0.911) and 4-day (0.902) sprouts. The 20-minute cowpea roasting to 105°C terminal grain temperature resulted in high (p less than 0.05) step 3 and total IVDMD coefficients. The lowest (p greater than 0.05) total IVDMD was recorded in 15-minute (0.883) (95°C terminal grain temperature) roasts. In both experiments 1 and 2, quantitative changes in IVDMD were consistent with the changes in the chemical components (ADF, NDF, fat, CP, minerals) and trypsin inhibitor activity. In conclusion, the compartmental and total IVDMD and quantitative change in chemical components and TIA indicated 4 days sprouting and 20-minute (105°C) roasting were respectively most effective for cowpea processing.\u0000","PeriodicalId":507727,"journal":{"name":"Indian Journal of Animal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141817613","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: Bypass fat, also called rumen-protected fat, boosts dairy animals¢energy for better milk production and health. Mineral deficiency is a leading cause of poor growth, weakened immunity, lower milk yield and reproductive issues in dairy animals. Considering the aforementioned details, an on farm trial was undertaken at farmer’s field to assess the effectiveness of bypass fat and mineral mixture on overall performance of milch buffalo. Methods: Twenty lactating Murrah buffaloes reared under farmer's field were selected and distributed equally in two groups of ten buffaloes in each group, i.e. T1 (control) and T2 (supplementation bypass fat @ 100 g and minerals mixture @ 50 g/day/ buffalo beside the farmer practices). Result: The outcome of study revealed that the additional of bypass fat and a mineral mixture had no effect on the weights of the buffaloes undergoing the experiment. Supplementation of bypass fat and mineral mixture did not influence the DM intake (in terms of kg/d and DMI %) in lactating buffalo. The mean milk yield during supplementation period was determined 10.19 ±0.36 and 12.13±0.43 l/day in group T1 and T2, respectively; which was 19.04 per cent higher in group T2 than the control. The average length of the postpartum estrus cycle (62.20±5.86 days) and service period (82.49±7.46 days) was significantly (P less than 0.05) reduced in supplemented group than control (86.40±11.57 days and 131.00±12.33 days, respectively) at farmer¢s field. AI per conception was also observed to be significantly (P less than 0.05) higher in non-supplemented group than the supplemented group. AI per conceptions in supplemented group and control group was recorded 1.39±0.33 and 2.71±0.44, respectively. It could be inferred from the observations that the feeding of bypass fat and area-specific mineral mixture in the diet significantly (P less than 0.05) improved the yield of milk and its composition as well as postpartum reproductive performance in milch buffalo at farmer’s field.

Background: Papillomatosis is a skin condition that is distinguished by benign proliferative tumors with a complicated etiology and epithelial proliferation. There is a need to perform a more thorough study on bovine papillomavirus and identify the virological properties of the agent in detail since a definitive treatment approach against this infection has not yet been completely identified and the suggested treatment outcomes differ. Methods: Samples were collected from warts developing on the teats of 500 cattle raised for milk production in Burdur Center and its districts. The samples were defrosted in order to extract DNA and the Dneasy Blood and Tissue Kit was used for the extraction procedure. By using a PCR assay, wart sample extracts were examined for 13 different BPV types (excluding BPV Type 7). For BPV type-specific primers, a protocol was utilized. Amplification products were demonstrated using agarose gel electrophoresis. Result: In the PCR test of 500 wart samples, BPV types (type 1-type 13) were detected in 378 (75.6%). In the general distribution of BPV types (single or mixed types) in teat warts, BPV-2 (n=85; 22.49%), BPV-8 (n=45; 11.90%), BPV-9 (n=48; 12.70%) and BPV-10 (n=52; 13.76%) were determined to be more common. In the study; it was determined that three different combined treatments provided 100% regression or complete recovery in warts developing on the teat of cattle. In conclusion; one of these three treatment combinations may be preferred for teat wart lesions in cattle.
