“…The heritability estimate of Ca (0.15) was of the same magnitude as that obtained by R eetz et al (1975), while the present estimate of 0.18 for Mg was lower. Both Ca and Mg had lower heritabilities than that estimated for the mineral selenium (L ingaas et al 1990).…”

Summary A study on heritabilities for 20 biochemical and immunological blood parameters was performed based on blood samples from pigs at a performance testing station belonging to the Norwegian Pig Breeders' Association. The heritability estimates for the blood parameters varied considerably. Two blood parameters (FFA, LDH) had h2 lower than 0.1, six were in the range 0.1‐0.2 (ALB, AP, Ca, CK, Mg, TG), five between 0.2‐0.4 (ALAT, CHOL, CREAT, GGT, LYA), while estimated values for the remaining seven were greater than 0.4 (AMYL, ASAT, C3, GLOB, HCA, IgG, TPROT). The medium sized or high estimates of heritability for some of the blood parameters related to disease resistance, are encouraging as far as indirect selection are concerned, because of practical difficulties in recording of some diseases in pig herds. Further studies to reveal the genetic correlation between the blood parameters, and between blood parameters and disease resistance, meat quality or performance traits, should be performed. Zusammenfassung Biochemische Blutwerte bei Schweinen. 2. Heritabilitätswerte für 20 Blutparameter Die Untersuchung über die Heritabilität von 20 biochemischen und immunologischen Blutwerten wurde an Schweinen einer Prüfstation des Norwegischen Schweinezüchterverbandes durchgeführt. Die Heritabilitätsschätzwerte zeigten erhebliche Variabilität; zwei Werte (FFA; LDH) hatten Heritabilitätswerte unter 0.1, sechs im Bereich von 0.1 bis 0.2 (ALB; AP; CA; CK; MG; TG); fünf zwischen 0.2 und 0.4 (ALAT; CHOL; CREAT; GGT; LYS) während bei den restlichen sieben sie über 0.4 lagen (AMYL; ASAT; C3; GLOB; HCA; IgG; PROT). Die mittleren bzw. hohen Heritabilitätsschätzwerte für einige Blutwerte, die in Verbindung mit Krankheitsresistenz sein könnten, sollten im Bezug auf indirekte Selektion ermutigend sein, vor allem da die Schwierigkeiten der Krankheitserfassung in Schweineherden erheblich sind. Weitere Untersuchungen hinsichtlich der genetischen Korrelation zwischen Blutwerten und zwischen diesen und Krankheitsresistenz, Fleischqualität‐ und leistungen sollten durchgeführt werden.

“…However, the level of selenium, which also has been reported to be associated with disease resistance (B run 1986), was higher in L than in the crossbred sows. This latter point is interesting because cereals grown in Norway have been found to be extremely poor in selenium (F rølie et al 1980), and because serum levels of both selenium and GSH‐Px have been shown to have high heritabilities (L ingaas et al 1991). Our results may indicate that in low selenium areas natural selection regarding the ability to absorb or conserve selenium may have been taking place.…”

“… IgG and Complement factor C 3 were measured by a turbidimetric, antibody‐based procedure using an automatic centrifugal analyser (Encore system II; Baker Instruments Corp.) according to the method described by B run et al (1989); Lysozyme and haemolytic complement activity were measured by an agar diffusion technique (L ie et al 1986), slightly modified and optimized for pig serum; Whole blood selenium levels were determined by atomic absorption using a hydride generation method (N orheim and H augen 1986); GSH‐Px activity in whole blood was determined using an automatic centrifugal analyser, Encore system II (L ingaas et al 1991);The following analyses were done using a Technicon RA‐1000 automatic analyzer: Alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), lactate dehydrogenase (LDH) and gamma‐glutamyltransferase (GGT) were analysed according to the recommendations of the Scandinavian and Dutch committees on enzymes. Alkaline phosphate (ALP) was analysed according to the recommendations of the Scandinavian committee on enzymes.…”

Summary Blood samples were drawn repeatedly from sows to detect quantitative variation in several blood parameters associated with disease resistance, performance or both. Pure Norwegian Landrace (L) sows, crosses between L and Duroc (L*D) and crosses between L and Yorkshire (L*Y) were compared. Blood samples were collected one and three months after farrowing, and repeatability, as well as effects of breed, of litter number and time of blood sampling, were estimated. Investigated were alanine aminotransferase, albumin, alkaline phosphatase, amylase, aspartate aminotransferase, calcium, cholesterol, complement factor C3, creatine kinase, creatinine, free fatty acids, gamma glutamyl transferase, globulin, glutathione peroxidase, haemolytic complement activity, IgG, lactate dehydrogenase, lysozyme activity, magnesium, total protein, triglycerides and selenium. The repeatability varied from 0.06 (creatine kinase) to 0.66 (selenium). Several blood‐parameters were influenced by breed (alanine aminotransferase, alkaline phosphatase, amylase, calcium, C3, gamma glutamyl transferase, globulin, IgG, lactate dehydrogenase, lysozyme, magnesium, selenium and total protein). Thirteen of the blood parameters were influenced by litter number, and fifteen were influenced by time of blood sampling after farrowing. The moderate and high repeatabilities, and the breed differences suggest that the levels of several of the investigated blood parameters is genetically regulated. Zusammenfassung Chemische Blutwerte bei Schweinen. 1. Wiederholbarkeit und Wirkungen von Rasse, Wurfzahl und Probennormen Wiederholte Blutproben wurden von Sauen zur Untersuchung quantitativer Variabilität einiger Blutwerte gezogen, die mit Krankheitsresistenz, Leistung oder beiden zu tun haben. Norwegische Landrasse (L) Sauen, Kreuzungen zwischen L und Duroc (L × D) und Kreuzungen zwischen L und Yorkshire (L × Y) wurden verglichen. Blutproben wurden ein und drei Monate nach dem Ferkeln gezogen und Wiederholbarkeit sowohl als auch Rassenwirkungen und Einflüsse von Wurfzahl und Blutentnahme geschätzt. Untersucht wurden: Alanin, Aminotransferase, Albumin, Alkaline Phosphotase, Amylase, Aspartat, Aminotransferase, Kalzium, Cholesterin, Komplement factor C3, Creatinkinase, Creatinin, freie Fettsäuren, Gammaglutamyl Transferase, Globulin, Glutathion Peroxydase, hämolithische Complementaktivität, IgG, Laktatdehydrogenase, Lysozyme Aktivität, Magnesium, Gesamtprotein, Triglyzeride und Selen. Die Wiederholbarkeit schwankte von 0.06 (Creatinkinase) bis zu 0.66 (Selen). Einige Blutwerte wurden durch Rasse beeinflußt (Alanin Aminotransferase, Alkaline Phosphotase, Amylase, Kalzium, C, Gamma Glutamyltransferase, Globulin, IgG, Laktat Dehydrogenase, Lysozym, Magnesium, Selenium und Gesamtprotein). Zwölf der Blutwerte wurden durch Wurfzahl und 15 durch Blutentnahme‐Termin beeinflußt. Die mittelhohen bis hohen Wiederholbarkeiten und Rassendifferenzen lassen vermuten, daß der Spiegel von einigen der untersuchten Blutwerte genetisch beeinflußt wird.

“…Infrequent incidence of selenosis has been reported on the Kendrick Project in central Wyoming. Tolerance to high Se levels varies considerably among individual animals and birds[22]. In addition, experimental evidence suggests that some animals can accommodate high levels of dietary Se after evidencing some symptoms of chronic toxicosis, such as lameness and hair loss (H. F. Mayland, personal observation).…”
