Skrzypczak","doi":"10.21005/asp.2021.20.3.07","DOIUrl":"https://doi.org/10.21005/asp.2021.20.3.07","url":null,"abstract":"Proteins in the urine of healthy individuals of various species are present in trace, practically immeasurable amounts. Under physiological conditions, the renal glomeruli filter out proteins with a molecular weight below 69 kDa, which are then almost completely reabsorbed in the proximal tubules. Occasionally, as an effect of low temperature, physical exercise, rapid change of body position, high-protein diet, medications, or at the end of pregnancy and in the postnatal period etc., proteins may be present in the urine of healthy individuals in higher amounts. This condition is referred to as physiological proteinuria. Most often, however, proteinuria is a symptom of a kidney disorder and may lead to further damage, eventually to renal failure. Proteinuria may be a result of: (a) increased penetration of proteins, mainly of low molecular weight, through the normal filtration membrane and the inability to absorb the increased amount of proteins in the proximal tubules – overflow proteinuria, (b) increased permeability of the glomerular filtration barrier, most often as a result of its damage – glomerular proteinuria, (c) damage to the renal tubules due to failure of reabsorption mechanisms – tubular proteinuria. Excretion of larger amounts of protein in the urine is always indicative of dysfunction of the kidneys and/or of the urinary tract. Having knowledge on the kind of excreted proteins (in terms of weight/size of the molecules) is very useful in medical and veterinary practice, as it enables early identification of the causes of proteinuria and distinguishing its etiology. In recent years, much attention has been paid to the role of uromodulin as a diagnostic marker of an early phase of renal dysfunction, especially of the tubules. The observations on the interaction of the digestive and excretory systems in the regulation of proteonemia in the postnatal period also seem to be important.","PeriodicalId":30932,"journal":{"name":"Acta Scientiarum Polonorum Zootechnica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45583084","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}

Only 10.9% of those were young farmers with age of 15 to 34 years old. According to the survey of animal industry in 2020, there were about 10,300 livestock farms and 9,900 poultry farms in Taiwan. For those of producing milk, meat and egg in different sectors, the average annual incomes per farm is more than 20 million Taiwan dollar in dairy cattle farms and broiler chicken farms with number of rearing animals per farm were 210 cows and 27,618 birds, respectively. Farm animal genetic resources of 117 breeds in Taiwan updated to 2021, including 20 native breeds, 43 imported breeds, 39 registered new breeds, and 15 ongoing selection breeds, serve as a gene bank for the study of genetic diversity. In Taiwan experience, mule duck production with two species crossbreeding via artificial insemination of laying duck sired with mixed semen from Muscovy duck, it is an essential application of multiple-sires instrumental breeding. In free range production, females of native chicken and laying duck can be multiple-sire natural mating to ensure a higher fertility rate of ovulated eggs. Application of frozen semen and embryo may perform sire-daughter mating, brother-sister mating, or son-dam mating for increasing genetic homogeneity without inbreeding depression of reproduction performance. Inbreeding quickly brings to the surface any detrimental genes that are in a population. With the facility of paternal DNA test, single-sire breeding can be used with extended semen and intra-uterine insemination to test the allele effect of sire genome on their economic traits of pig, cattle, goat, and poultry breeds in a small-scale farming system. Advanced breeding efforts are undertaken to broaden the genetic base of conserved animals and create new breeds that meet the manifold demands in relation to quality, resilience, and sustainability in small-scale farms.","PeriodicalId":30932,"journal":{"name":"Acta Scientiarum Polonorum Zootechnica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42727086","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}

Level of milk dry matter (MDM) (%) is of great importance. The material of this study consisted of 2208 milking records of dairy cattle yielding more than 40 l per day from Polish Holstein Friesian population. In this study to estimate the milk dry matter, regression of daily milk yield (MY) (l), milk urea (MU), milk protein (MP) (%) and milk fat (MF) (%) as explanatory variables were used. To estimate the best fitting, curve estimation was used. Estimation of the curves showed that milk urea was cubic, milk yield, milk protein and milk fat were quadratic. To avoid multicollinearity where VIF value greater than 10, stepwise variable selection procedure was used. After variable selection the regression equation was obtained as MDM=2.879+1.290*MF+2.395*MP-0.039*MF^2–0.225*MP^2 with 0.946 coefficient of determination. Our results showed that milk fat (%) and milk protein (%) can be used to estimate the milk dry matter (%) with a great achievement in high milk yielding dairy cattle.","PeriodicalId":30932,"journal":{"name":"Acta Scientiarum Polonorum Zootechnica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48490465","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}
