The production of goat's milk under extensive grazing is very important to ensure an adequate growth of the progeny, but the productivity of local does and their progeny is not accurately characterized, particularly in the semi–arid Region of Northern Mexico. The aim was to evaluate the productive potential performance of local does and their offspring, when does are offered a supplementary feeding program in pre and post–partum period. Twenty–four local does and their progeny (n=40) were used and divided into two groups: 1) Control group; does fed exclusively on grazing, 2) Supplemented group; does were supplemented at 1.5% of live weight 45 d before and 45 d after parturition. Differences due to treatment were found (P<0.05) for kid´s weight at sale (KWS), kid´s age at sale (KAS), kid´s daily weight gain (KDWG) and doe’s milk production (DMP). Kid’s mortality percentage and birth weight, milk fat content and doe’s live weight did not differ between treatments (P>0.05). High positive correlations between kid´s weight at birth (KWB) and KWS and KDWG were found (P<0.0001), but it was negative with KAS. On the other hand, KWS was positively correlated (P<0.05) with KDWG and DMP. Finally, KAS was negatively correlated with KDWG (P<0.0001) as well as KDWG with DMP (P<0.001) and protein content (P<0.05). Its concluded that pre and postpartum supplementation in local does helps to express the productive potential for milk production, plus protein and lactose contents at starting of lactation, which in turn enhanced the performance of their progeny.

The records of Leptospira spp. in bats from México are scarce. It is known that several species of bats are hosts of pathogenic Leptospira spp.; therefore, they participate in the epidemiological cycle and can generate transmission scenarios to people and animals. The aim was to detect the DNA of Leptospira spp. in bats captured in four sites from the Yucatán Peninsula, México. A kidney fragment was collected from the bats and used to extract genomic DNA. Using a PCR, the DNA of Leptospira spp. was detected. Fifty–four bats of the species Desmodus rotundus, Mimon cozumelae, Pteronotus mesoamericanus, Pteronotus fulvus, Nyctinomops laticaudatus, Peropteryx macrotis, Molossus nigricans, Molossus aztecus, Noctilio leporinus, Saccopteryx bilineata and Mormoops megalophylla were studied. The PCR yielded a total frequency of Leptospira spp. of 44.4% (24/54, 95% CI 36.2–71.7%). Species with at least one positive individual were D. rotundus, M. cozumelae, P. mesoamericanus, N. laticaudatus, P. macrotis, M. nigricans, N. leporinus, M. aztecus, and S. bilineata. A high frequency of Leptospira spp. was found in different species of bats belonging to several trophic guilds. The presence of Leptospira spp. in bats is relevant for Public and Animal Health because the evidence indicates that they can generate zoonotic transmission cycles.
在墨西哥的蝙蝠中钩端螺旋体的记录很少。已知几种蝙蝠是致病性钩端螺旋体的宿主。因此，它们参与流行病学周期，并可能产生向人和动物传播的情景。目的是检测在墨西哥Yucatán半岛四个地点捕获的蝙蝠的钩端螺旋体的DNA。从蝙蝠身上收集了一个肾脏碎片，用于提取基因组DNA。采用PCR法检测钩端螺旋体的DNA。对54种蝙蝠进行了研究，包括圆齿蝠、长齿蝠、中美洲翼蝠、黄翅蝠、长尾翼蝠、大翅蝠、黑翅蝠、阿兹特翼蝠、细尾翼蝠、双翼翼蝠和巨叶翼蝠。钩端螺旋体总感染率为44.4% (24/54,95% CI 36.2 ~ 71.7%)。至少有1个阳性个体的种为圆齿棘球绦虫、cozumelae、中美洲棘球绦虫、laticaudatus、macrotis、nigricans、leporinus、aztecus和bilineata棘球绦虫。钩端螺旋体在不同种类的蝙蝠中有较高的传播频率。蝙蝠中钩端螺旋体的存在与公共和动物卫生有关，因为有证据表明它们可以产生人畜共患传播循环。

This study aimed to investigate the effect of Aspalathus linearis on the expression levels of major histocompatibility complex (MHC) molecules and their ability to present antigens to CD8, CD68, and T cells in an experimental rat model of gastritis. Furthermore, changes in tumor necrosis factor–alpha (TNF–α), myeloperoxidase, superoxide dismutase, and malondialdehyde levels due to the antioxidant properties of the plant were evaluated. The study included 24 female Wistar albino rats (Rattus norvegicus). A. linearis was administered to the treatment groups of an ethanol–induced gastritis rat model via oral gavage for 5 days the blood and stomach tissues were sampled for analysis. Biochemical evaluation revealed that TNF–α and myeloperoxidase levels decreased and superoxide dismutase activity increased in the A. linearis–treated groups compared with the ethanol–treated group. Histochemical evaluation revealed that the severity of inflammation decreased in the rats with gastritis treated with A. linearis. In addition, the number of cells expressing CD8 and CD68 decreased. The number of MHC–II immunopositive cells was higher in the A. linearis–treated group compared with the control and other treatment groups. A. linearis exhibits a protective effect on gastric mucosa by reducing the severity of oxidative stress owing to its antioxidant, anti–inflammatory, and antiapopitotic properties.

Cyclophosphamide (CP) is one of the frequently preferred chemotherapeutic agents Worldwide. CP has negative effects on the testes, spermatogenesis, and reproductive hormones. The aim of this study was to determine the protective effect of Coenzyme Q10 (CoQ10) on the damage caused by CP. CoQ10 is use in the treatment of infertility problems and is naturally found in the testes and seminal fluid. Thirty–six Albino Wistar male rats were divided into six groups (Control, Sham, Cyclophosphamide (CP), Coenzyme Q10 (CoQ10), CP + CoQ10 I, CP + CoQ10 II), with six animals in each group. Semen analysis included investigations of sperm DNA damage, motility, abnormal sperm ratio, and density. Histopathological examination and assessment of oxidative stress parameters in the testes were conducted. Additionally, serum levels of FSH, LH, and Testosterone were measured. CoQ10 administration increased the motility rate, density, and Testosterone levels in testicular damage caused by CP (P<0.05). Furthermore, it was observed that the abnormal sperm ratio, sperm DNA damage, and oxidative stress were reduced (P<0.05). Based on the results of this study, the use of CoQ10 in conjunction with CP has the potential to alleviate male infertility problems that may arise from CP administration.

The aim of this study was to determine the effects of alone and combined treatment of Tarantula cubensis alcoholic extract (TCAE) and Methenolone Enanthate (ME) on morphometric parameters of humerus and femur in young rats. In this study, 36 five–week–old Wistar Albino rats were used. The animals were divided into 4 groups; Control group (n:6, normal saline solution, 0.2 mL·rat-1, subcutaneously –SC–), TCAE group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC), ME group (Methenolone Enanthate), 10 mg·kg-1, intramuscularly –IM–) and TCAE + ME group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC + Methenolone Enanthate, 10 mg·kg-1, IM). Drug treatments were done once a week for 7 weeks. At the end of the experiment, all the animals were euthanized and their humerus and femur bones were resected and their morphometric parameters were determined. No statistical differences were determined (P>0.05) between the groups in terms of the anatomical reference points (length, corpus thickness, cavum medullare diameter, and cortex thickness) of humerus and femur bones. In conclusion, it was found that alone and combined treatments of Tarantula cubensis alcoholic extract and ME (at normal dose) had no effects on morphometric parameters of humerus and femur bones in rats in the growing period. However, these effects may not be observed at high–dose and long–term treatments in rats.

This study investigated the hormonal, inflammatory, oxidant–antioxidant, and histopathological effects of exogenous Melatonin administration on Spermatogenesis in rats' chronic unpredictable stress model (CUSM). In the study, stress caused a decrease in follicle stimulating–hormone (FSH), luteinizing hormone (LH), Testosterone, Melatonin, Glutathione (GSH), Glutathione peroxidase (GSH–Px), catalase, interleukin 10 (IL–10) levels and motility, and an increase in Corticosterone, nuclear factor kappa beta (NF–kB), tumor necrosis factor–alpha (TNF–α), interleukin 1 beta (IL–1β), interleukin 6 (IL–6), abnormal sperm, dead/live sperm ratio and exogenous Melatonin reduced inflammatory cytokines and oxidative stress and improved spermatological parameters (P<0.05). Melatonin also partially corrected stress–induced changes in testicular morphology. As a result, using Melatonin in rats with CUSM may be effective in improving spermatological parameters through anti–inflammatory and antioxidant mechanisms.

Oocyte maturation is a critical step for in vitro embryo production. In female cats, findings on the influence of the estrous cycle stage on oocyte quality and maturation are contradictory. Little is known about this phenomenon in female cats in the tropics. This study aimed to assess the effect of the estrous cycle stage on oocyte quality and subsequent capacity to complete nuclear maturation in cats in a tropical environment. Ovaries from 18 sexually matured cats were collected during ovariohysterectomy. Cumulus–oocyte complexes (COCs) were released from follicles by slicing and fragmentation of the ovarian cortex. According to morphological characteristics, COCs were classified into grades I–II (suitable) and III–IV (no suitable). Only suitable COCs from each cat were cultured for in vitro maturation. Nuclear oocyte maturation was assessed by the presence of a telophase I or metaphase II plate with extrusion of the first polar corpuscle. A significantly greater number of oocytes per ovary were collected from queens in inactive than in follicular or luteal phase. Proportions of suitable COCs were similar among groups. Rate of oocyte maturation did not differ among stages of the estrous cycle, nor did the proportion of non–matured or degenerated oocytes. The age of the queens did not affect the percentage of oocyte maturation. In conclusion, the quality and rate of oocytes maturation were similar in the three stages of estrous cycle examined.

Ovaries from 18 sexually matured cats were collected during ovariohysterectomy. Cumulus–oocyte complexes (COCs) were released from follicles by slicing and fragmentation of the ovarian cortex. According to morphological characteristics, COCs were classified into grades I–II (suitable) and III–IV (no suitable). Only suitable COCs from each cat were cultured for in vitro maturation. Nuclear oocyte maturation was assessed by the presence of a telophase I or metaphase II plate with extrusion of the first polar corpuscle. A significantly greater number of oocytes per ovary were collected from queens in inactive than in follicular or luteal phase. Proportions of suitable COCs were similar among groups. Rate of oocyte maturation did not differ among stages of the estrous cycle, nor did the proportion of non–matured or degenerated oocytes. The age of the queens did not affect the percentage of oocyte maturation. In conclusion, the quality and rate of oocytes maturation were similar in the three stages of estrous cycle examined.","PeriodicalId":32316,"journal":{"name":"Revista de la Facultad de Ciencias Economicas","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81459289","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}

This study was carried out on Bafra (Chios × Karayaka) breed to determine the fertility characteristics of sheep, growth performance, survivability and carcass weights of lambs. For this purpose, the reproductive characteristics of 600 sheep aged 2–5 years and the survivability of 1,150 lambs born from these sheep were determined. In addition, the growth performance characteristics, slaughter, and carcass weights of 65 lambs born from 38 randomly selected ewes 3–4 years old were determined. In the study, the pregnancy rate was 90.00%, the birth rate was 87.16%, singleness 15.00%, twins 80.00%, and triplet 5.00%, lamb yield per ewe 1.90, number of lambs per birth 2.20 was calculated. Birth and weaning (90th d) weights as well as 61–90th d of live weight gains of male and female lambs were found as 4.26 and 3.57 kg, 24.15 and 21.32 kg, 265.75 and 231.72 g, respectively. The 120th d survivability, slaughter and carcass weights and carcass yields of lambs were determined as 97.74%, 47.10 kg, 21.61 kg and 45.92%, respectively. As a result, although the Bafra sheep is a breed that can be recommended to be raised in terms of the characteristics discussed, more scientific research is needed on it.

This study aimed to determine proximate analysis and fatty acid profile of whole body muscle tissue (WM) and muscles in different parts of the body, including dorsal (D), ventral (V), and caudal (C) regions, of the crimean barbel (Barbus tauricus), which is an species caught from the Gelingüllü Dam. In whole body muscle the protein, lipid, moisture, and ash contents of the fish were 18.61, 1.54, 78.49, and 1.09% respectively. The lipid contents of crimean barbel varied between 1.78 and 2.68%, with the highest and lowest percentages in the C and V regions, respectively. There was a significant difference (P<0.05) in the fatty acid content present in the different parts of the fish. The highest and lowest proportions of saturated fatty acids (SFA) were found in WM (23.03) and D (21.94%) region, respectively. The highest and lowest monounsaturated fatty acid (MUFA) contents were found in the D muscle (36) and V muscles (33.73%), respectively. The proportion of polyunsaturated fatty acids (PUFA) was highest and lowest in C (25.63) and D (22.62%) regions, respectively. The highest eicosapentaenoic acid (4.11) and docosahexaenoic acid (12.98%) contents were found in V and C regions, respectively. The results showed that lipid content and composition of fatty acids may vary in the different body parts of the fish.
