A cross-sectional study was conducted from December 2019 to May 2020 to determine the seroprevalence and identify potential risk factors of brucellosis in dairy cows and owners. Purposive sampling was performed in the respective farms and kebeles to screen recent cases of abortion. The overall seroprevalence of bovine and human brucellosis was 0.61% (95%CI:0.016–2.09) and 1.21% (95%CI:0.032–4.27) respectively using combined RBPT and CFT tests. Late stage of abortion (OR = 14.74, p = 0.0002), retained fetal membrane (OR = 32.74, p = 0.006), market-based stock replacement (OR = 16.55, p = 0.002), and presence of parturition pen (OR = 11.511, p = 0.027) was found to be significantly associated with seropositivity for Brucella infection in dairy cattle. Human housing (OR = 1.8, p = 0.002), contact with aborted fetus (OR = 21.19, p = 0.017), and drinking raw milk from aborted (OR = 5.72, 0.019) and retained fetal membrane (OR = 4.22, p = 0.029) cows all had a significant influence on human brucellosis seropositivity. A structured interview question was administered to 284 respondents. Accordingly, most respondents had no knowledge of bovine brucellosis and their zoonotic effects (93.3%) in contrast most of them drink raw milk. Implementation of a test and slaughter strategy with compensation is recommended with this low prevalence. In the case of human brucellosis, implementing one health approach framework should be practiced.
2019年12月至2020年5月进行了一项横断面研究，以确定奶牛和奶牛主人的布鲁氏菌病血清阳性率并确定潜在危险因素。在各自的农场和卫生院进行了有目的的抽样，以筛查最近的堕胎病例。采用RBPT和CFT联合检测，牛和人布鲁氏菌病的总血清阳性率分别为0.61% (95%CI: 0.016-2.09)和1.21% (95%CI: 0.032-4.27)。流产后期(OR = 14.74, p = 0.0002)、胎膜残留(OR = 32.74, p = 0.006)、市场置换(OR = 16.55, p = 0.002)和产房栏存在(OR = 11.511, p = 0.027)与奶牛布鲁氏菌感染血清阳性显著相关。人的居住环境(OR = 1.8, p = 0.002)、接触流产胎(OR = 21.19, p = 0.017)、饮用流产牛(OR = 5.72, 0.019)和残留胎膜(OR = 4.22, p = 0.029)的生乳对人布鲁氏菌病血清阳性均有显著影响。对284名受访者进行了结构化访谈。因此，大多数应答者不了解牛布鲁氏菌病及其人畜共患效应(93.3%)，相比之下，大多数应答者饮用生奶。鉴于这种低流行率，建议实施带有补偿的检测和屠宰策略。就人类布鲁氏菌病而言，应实行一种卫生方针框架。

ABSTRACT The poultry population in Africa is mostly composed of local or indigenous chickens appreciated for the unique taste and texture of their meat. However, with the ever-increasing population growth, the free-range or backyard poultry farming system is no longer adapted to supply people with protein requirements. Crossbreeding local hens with an improved rooster weakens the thermotolerance and disease resistance of the offspring in African areas. In this context, the available breeds need to be preserved. The improvement of their productivity should be actualized through the implementation of a sustainable production programme that is simple and less expensive for the farmer, taking into account: feeding, habitat and chicken care. Scientific research should invest more time on the identification and characterization of all available breeds or chicken ecotypes allowing us to know production performances and their nutritional needs. Feeding with locally available resources, vaccination and use of indigenous medicine requiring training of farmers are essential perspectives. This paper focused on the productivity and resilience of indigenous chicken ecotypes in various African tropical environments and some essential factors to improve the birds. For this, a critical analysis was made based on the available data on the birds from research databases.

ABSTRACT The willingness of consumers to buy animal welfare products is an important support for the transformation of animal husbandry to animal welfare. However, animal welfare farming often means a considerable capital investment, which often increases the likelihood of price increases for the products. The main purpose of this study is to assist in the marketing of animal welfare products through the research results and then promote the transformation of animal husbandry to animal welfare-friendly agriculture. The analysis results showed that consumers’ moral attitudes towards animal products significantly affect perceived higher prices and buying willingness, while perceived higher prices negatively affect buying willingness. Still, fortunately, the negative impact is not significant. Based on the findings, a discussion of academic and managerial implications is provided at the end of this article.

ABSTRACT The aim of this study was to determine the prevalence of bacteria Dichelobacter nodosus (D. nodosus) and Fusobacterium necrophorum (F. necrophorum) in non-lame dairy cows on eight Slovak dairy herds. In total, 1,631 Holstein Friesian dairy cows were included in the study. Information of the cows was collected from on-farm software included cow ID, lactation number (heifer/cow), year milk yield (kg), and DIM on collection date. The PCR method detected D. nodosus and F. necrophorum on the feet of 1,394 (85.5%) and 373 (22.1%) dairy cows, respectively (p < 0.05). No dairy farm could be found without positive samples for D. nodosus and the majority of the farms were free or had very low prevalence of F. necrophorum (0–9.1%). Statistical difference for the prevalence of D. nodosus and F. necrophorum in different Slovak regions was detected for both strains. Logistic regression revealed an association between both D. nodosus and F. necrophorum identification and annual milk production (odds ratios = 0.69 and 0.32, respectively). Our data demonstrates that D. nodosus is present on the feet of almost every dairy cow what means a potential risk for cattle to develop foot rot. Furthermore, both bacteria are associated with decreased annual milk production.

ABSTRACT The objective of this study was to evaluate the effect of a low dose of hCG or FSH on follicle growth and pregnancy per artificial insemination (AI) in crossbreed beef heifers subjected to a split-time AI program. All heifers (n = 386) were subjected to a 7-d Co-synch protocol and an intravaginal controlled internal drug release (CIDR) device (GnRH and CIDR insertion; 7 days later PGF2α, CIDR removal, and application of a tail head estrus detection patch; 36 hours later AI of heifers detected in estrus, 24 hours later timed AI of remaining heifers). At CIDR removal, heifers were randomly assigned to receive either 150 IU of hCG, 20 mg of FSH, or remained as untreated controls. The diameter of the preovulatory follicle and the pregnancy per AI did not differ among treatments. A smaller (P = 0.035) proportion of heifers in the hCG group were detected in estrus compared with control. Additionally, the incidence of premature ovulation was greater (P < 0.01) among heifers treated with hCG compared with control. In conclusion, using a low dosage of hCG or FSH at the time of device removal did not affect pre-ovulatory follicle growth or the proportion of pregnant heifers.

ABSTRACT The objective of this study was to evaluate sorghum hybrids associated or not associated with Azospirillum brasilense and nitrogen fertilization (N) during planting on the yield, fermentative profile, and nutritional value of the respective silages. Five sorghum hybrids (Volumax, 201813B, 201814B, 201709B, BRS716) were evaluated with three nitrogen fertilization strategies using urea (100 kg ha−1 of N) and Azospirillum brasilense, and urea (100 kg ha−1 of N)/A. brasilense in association. A randomized block design was used in a 5 × 3 factorial scheme, with five hybrids, three fertilization strategies and three replications (blocks). The useful area of each experimental unit was 3 m x 3 m. The biomass sorghum hybrids showed a dry matter (DM) production (P = 0.01) 48.31% higher than the DM production of the Volumax forage (mean of 17.49 t ha−1 of dry matter). There was no difference between the sorghum hybrid silages in the pH values (mean of 4.11; P = 0.68), gas losses (mean of 3.74% of DM; P = 0.19). The sorghum hybrids biomass 201709B and BRS 716 showed better digestible and DM productivity. Azospirillum brasilense can be used as a nitrogen fertilization strategy in partial or total replacement of urea.

ABSTRACT The study was conducted to determine the effects of supplementing probiotics and concentrates on intake and growth performance of Sahelian does fed Brachiaria decumbens grass. Twenty-four Sahelian does averaging one year and weighing 13.3 ± 1.16 kg were assigned randomly in a 2 × 2 factorial arrangement to four treatments in a Completely Randomized Design with 6 replicates and used to measure intake and live weight changes for 14 weeks. The factors were levels of concentrate and probiotics. Blood samples were taken for the determination of haematological and biochemical parameters. The results revealed differences (P < 0.05) in total dry matter intake, live weight changes and feed conversion ratio attributable to treatment effects. The differences observed in total dry matter intake led to improvements in average daily gain, feed conversion ratio and growth rate. All blood haematological indices with the exception of mean cell volume were impacted positively by treatment effects. White blood cell and total protein contents improved linearly with probiotics and higher level of concentrate supplementation, while total cholesterol content declined (P < 0.05). The results highlighted the positive impact of probiotics and higher level of concentrate supplementation on growth performance and blood profile of growing Sahelian does on a basal diet of Brachiaria decumbens grass.

ABSTRACT A species of catfish belonging to the Anguilla genus called Anguilla marmorata has long been exploited and grown in Vietnam. Marbled eels are regarded as a specialty seafood species with several therapeutic and nutritive benefits. This study used High-Performance Liquid Chromatography (HPLC) to identify various biochemical and nutritional ingredients in A. marmorata collected in its natural habitat. There was 16 different amino acids analysed in the muscle, skin, and mucus of marbled eels at the rates of 14.01%, 5.48%, and 9.96%, respectively. Twenty-four fatty acids were found in muscle and skin, while only nine fatty acids were detected in the mucus with proportions of 11.93, 25.91, and 0.37 g/100 g, respectively. Six different vitamins (A, B3, B5, D3, C, E) are found in the muscle of the eel; five types of vitamins (A, B3, B5, D3, E) were detected in the skin; and three vitamins (B3, B5, C) are found in mucus. Using HPLC analysis has shown remarkable effectiveness in micronutrient analysis in nutritional research. The results will increase our knowledge of the nutritive benefits of the A. marmorata and point the way toward the creation of functional foods and cosmetics with natural ingredients that may be used on people.

Six different vitamins (A, B3, B5, D3, C, E) are found in the muscle of the eel; five types of vitamins (A, B3, B5, D3, E) were detected in the skin; and three vitamins (B3, B5, C) are found in mucus. Using HPLC analysis has shown remarkable effectiveness in micronutrient analysis in nutritional research. The results will increase our knowledge of the nutritive benefits of the A. marmorata and point the way toward the creation of functional foods and cosmetics with natural ingredients that may be used on people.","PeriodicalId":15030,"journal":{"name":"Journal of Applied Animal Research","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48664239","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}

ABSTRACT The objective of the study was to establish baseline thermographic information on body and udder skin surface temperature (USST) of lactating cows in different stages of lactation, milk yield, parity, breed and season. Holstein Friesian crossbred (n = 19 cows) and Deoni lactating cows (n = 14 cows) were monitored for body (i.e. eye) and USST prior to milking using a forward looking infra-red (FLIR) camera. It was observed that the mean body and USST of both crossbred and Deoni cows did not differ significantly. The body and USST of both the breeds were significantly higher by 0.9–1.0°C during evening than morning milking. There was no difference in body and USST between days and between udder quarters. Similarly, stage of lactation, milk yield and parity did not show any influence over body and USST. The body and USST were higher in summer (1.1°C) than in spring and winter seasons. Deoni cows had 1.0°C lesser body and USST than crossbred cows. It is concluded that baseline thermographic information on body and USST would be useful in developing breed-specific thermographic signature for individual animal.

ABSTRACT The functions of tumour protein, translationally controlled 1 (TPT1), have been extensively researched in various cell types. Although TPT1 was reported to have accelerating effects on the lipid deposition of mouse hepatocytes, and the activation roles in phosphatidylinositol 3 kinase (PI3K/AKT) pathway, its role in the differentiation of ovine stromal vascular fractions (SVFs) and their underlying mechanisms have not been addressed. Therefore, the objective of this study was to explore whether TPT1 participates in the adipogenic differentiation regulation of ovine SVFs and the underlying mechanisms. The results from this study revealed that TPT1 was abundant in the tail fat of sheep and the protein was located in the nucleus of C3H10T1/2 cell line and ovine SVFs. Moreover, TPT1 expression was up-regulated during the adipogenic differentiation of SVFs. The overexpression of TPT1 dramatically accelerated the adipogenic differentiation of SVFs, accompanied by the up-regulation of adipogenic marker genes, while TPT1 inhibition had opposite effects. TPT1 also had a negative effect on forkhead box O1 (FOXO1). The PI3K/AKT pathway was involved in the promotion of adipogenesis induced by overexpressing TPT1. We concluded that TPT1 promotes the adipogenic differentiation of ovine SVFs through PI3K/AKT-dependent pathway and attenuates the expression of FOXO1 in ovine SVFs.
