| Description
| - This paper deals with changes in the basic composition of sheep colostrum within the first 72 hours after parturition on the one hand and with the possibility of determination of the major components of sheep colostrum by near-infrared spectroscopy on the other. Levels of essential, non-essential and total amino acids in sheep colostrum were determined by near-infrared reflectance spectroscopy (NIRS). For each component, sets of 90 samples were used to calibrate the instrument by means of a modified partial least-square regression. Values of correlation coefficients (r) were as follows: 0.979 for Thr; 0.954 for Val; 0.968 for Leu; 0.918 for Ile; 0.946 for Lys; 0.908 for Arg; 0.845 for His; 0.999 for Trp; 0.915 for Phe; 0.909 for Met; 0.939 for Cys; 0.911 for Met+Cys; 0.933 for Tyr; 0.945 for Asp; 0.935 for Glu; 0.986 for Ser; 0.985 for Pro; 0.957 for Gly; 0.949 for Ala; 0.940 for EAA; 0.958 for NEAA and 0.977 for AA. Partial least squares (PLS) regression was used to develop calibration models for exa

- Práce řeší změny aminokyselinového složení ovčího mleziva v průběhu 2 -- 72 hod. po porodu a možnost použití blízké infračervené spektroskopie pro jejich stanovení. Dynamika a změny obsahu aminokyselin byly sledovány u 10 kříženek (F111) plemene východofrízská ovce x zušlechtěná valaška (EF87IV) na druhé a vyšší laktaci. Korelační koeficienty pro kalibrační model byly zjištěny: Thr 0,979; Val 0,954; Leu 0,968; Ile 0,918; Lys 0,946; Arg 0,908; His 0,845; Trp 0,999; Phe 0,915; Met 0,909; Cys 0,939; Met+Cys 0,911; Tyr 0,933; Asp 0,945; Glu 0,935; Ser 0,986; Pro 0,985; Gly 0,957; Ala 0,949; EAK 0,940; NEAK 0,958 a 0,977 pro AK. Korelační koeficienty aminokyselin pro validační model činily Thr 0,959; Val 0,912; Leu 0,936; Ile 0,855; Lys 0,903; Arg 0,853; His 0,717; Trp 0,667; Phe 0,854; Met 0,867; Cys 0,895; Met+Cys 0,868; Tyr 0,886; Asp 0,910; Glu 0,882; Ser 0,968; Pro 0,968; Gly 0,923; Ala 0,916; EAK 0,901; NEAK 0,923 a AK 0,943. Konstruovaný kalibrační model plně odpovídá validovaným hodnotám. (cs)
