Noise is any unwanted chronic or intermittent sound and the amount and type of noise sources are related to the cattle production system. The aim of the review was to highlight the literature regarding noise as a robust environmental stressor and the following impact on the behavioural, physiological and performance reactions of cattle. In addition, it was shown how often this problem is discussed in the scientific literature. Review was conducted with a search strategy of peer-reviewed articles written in English before June 2022. The systematic searches were performed using the Web of Science and Scopus databases with the integration of Boolean operators to string together words or phrases. It is recommended to create an environment around cows in which the acoustic stimuli affecting the animals are under their control. Therefore, if the sound source cannot be eliminated, animals should be able to choose places with a lower sound intensity appropriate for the perceptual abilities of cattle. On the other hand, attention is paid to the positive aspects of some groups of sound signals i.e. positive nature of music for cows and people during milking. The scientific publications analysed by the methodology drew attention to the repeatability of the discussed results. Further research on this subject should be considered because developing farms use modern solutions in barns which can negatively affect the acoustic comfort of cows, and their impact has yet to be determined.","PeriodicalId":8235,"journal":{"name":"Annals of Animal Science","volume":"23 1","pages":"717 - 723"},"PeriodicalIF":1.9,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47896528","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}

Ultrasonograms of mammary glands in coronal (C) and sagittal (S) planes were obtained using 5.0- and 7.5-MHz transducers from four Polish Mountain (PMt) and six Olkuska (Olk) ewes. Computerized image analyses of all images have been performed to determine pixel intensity (numerical pixel values-NPV) and heterogeneity (pixel standard deviation-PSD) of the mammary gland stroma/parenchyma. In PMt ewes examined with the 5.0-MHz probe, the mean NPV-C correlated negatively with C17:0 (margaric acid) and C17:1 c10 (heptadecenoic acid). Furthermore, NPV-S correlated negatively with C17:0 content of milk. In PMt ewes examined with the 7.5-MHz transducer, the mean NPV-S correlated positively with the crude fat and total solids, and negatively with C18:3 c9, c12, c15 (n-3) (α-linoleic acid) content of milk samples, while PSD-S correlated positively with C16:0 (palmitic acid) and negatively with lactose. In the scans obtained with the 5.0-MHz in Olk sheep, the mean NPV-C was directly related to C10:1 (decanoic acid), C14:1 (myristoleic acid), C16:1 iso (iso-hexadecanoic acid), C16:1 c9 (palmitoleic acid), and C18:0 (stearic acid) content; the mean PSD-C correlated positively with total solids, C14:1, C15:0, C16:0, C16:1 iso, C16:1 c9, CLA (conjugated linoleic acids), and total saturated fatty acid content, and negatively with C18:1 c11 (n-7) (cis-vaccenic acid), C18:2 c9,c12 (n-6) (linoleic acid), and total polyunsaturated fatty acid content of milk; and the mean PSD-S correlated directly with ash and total saturated fatty acid content of the milk. Lastly, the mean NPV-C of images recorded with the 7.5-MHz probe in Olk ewes related directly to ash and C12:0 (lauric acid); the mean NPV-S related directly to ash and C16:1 iso; the mean PSD-C correlated positively with ash and total saturated fatty acid (SFA) content, and the mean PSD-S correlated positively with the total SFA. Echotextural attributes of the mammary gland in ewes have the makings of the technique for determining milk content of certain chemical constituents in a breed-specific manner; however, further studies are needed to verify the usefulness of echotextural analyses of the udder to consistently predict complete milk composition.","PeriodicalId":8235,"journal":{"name":"Annals of Animal Science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46012524","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 present overview aimed to evaluate the effects of farrowing induction on farrowing duration, birth interval, birth weight, dystocia/birth assistance, and stillbirth in pigs. The results showed that via different routes of administration, either natural or synthetic prostaglandins alone or in combination mostly with uterotonic drugs, including oxytocin and carbetocin, have been used for the induction of farrowing. Sometimes other drugs, such as dexamethasone, estradiol, xylazine, ergometrine, and AGN190851, were added. Vulvar and perinatal routes reduced the intramuscular dose of prostaglandins by 50% to 75%, while equal effects remained. A split dose of prostaglandin 6 h apart should be used because it may enhance complete luteolysis. Additionally, if uterotonic drugs are used following prostaglandin injection, they should be injected after the birth of the first piglets at the earliest timepoint to ensure full opening of the cervix. These two practices decrease the farrowing duration, the birth interval, and dystocia. Induction should not be conducted more than 2 days earlier than the expected farrowing date in order to keep the stillbirth rate and birth weight unaltered. This review also revealed that certain factors, such as the rate of farrowing supervision, natural differences in piglets’ birth weights, litter size, gestation length, and treatment with altrenogest before induction, may be confounding factors that possibly alter the effect of induction programs on certain farrowing characteristics.","PeriodicalId":8235,"journal":{"name":"Annals of Animal Science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42739473","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}

Biofloc technology (BFT) is accepted as a novel sustainable method that reduces the pollution load on receiving water resources with its zero-water-discharge approach, eliminates extra water treatment costs with its biological cycles, and supports the growth performance of reared animals and thereby reduces feed costs. However, each BFT system has its own set of difficulties and obstacles. This review focuses on the advantages and disadvantages of BFT systems in terms of economy, sociability and applicability. The BFT shows more effective results in the conversion of toxic nitrogenous compounds to nontoxic compounds compared with the technologies based on nitrification processes. In addition, the growth performance and health of the cultured animals are generally better in BFT systems than those in conventional rearing systems (continuous water flow). The risk of common diseases occurrence due to pathogenic microorganisms appears to be lower in BFT systems compared to conventional aquaculture. It is also noteworthy that the immune system, biochemical stress indicators and antioxidant activities of organisms held in BFT systems are positively affected. In BFT systems based on microbial activity, the high water temperature demanded by bacteria is a limiter for the system. Moreover, a higher aeration/energy requirement is the case in BFT to meet the oxygen demand of all organisms including fish, shrimp, heterotrophic bacteria, nematodes, rotifers and others inside. There is also another concern about the acceptability potential of the cultured organism in BFT systems for consumption. Finally, since the high temperature demand of the system will create high energy costs, it should be considered as another restriction that forces the application. Considering the advantages and disadvantages of BFT systems as sustainable aquaculture, this review provides a guide for future studies and full-scale implementations.","PeriodicalId":8235,"journal":{"name":"Annals of Animal Science","volume":"0 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69171030","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 results indicate that the phytobiotic product beneficially altered feed, fillet and serum oxidative status and improved performance of trouts. Also, oregano essential oil beneficially affected the histopathology and histomorphometry of intestine and skin. Moreover, oregano oil addition in the rainbow trout diet can initiate mitogenic and anti-apoptotic responses in the liver, which is one of the main actions of IGF-1 receptor promoting body growth and health.

The experimental diets were fortified with chitosan powder at 0, 250, 500, and 1000 mg per kg diet, respectively. It was found that final weight, specific growth rate, daily weight gain, and feed: gain enhanced linearly (P<0.05) with increasing chitosan levels in the diet. No significant differences were found for all slaughter traits, including hot carcass weight, carcass yield, and internal organ weights, besides carcass parts, including head, fore, intermediate and hind parts.
