“…The reason for that incompatibility could be discussed in the light of concentrate composition that may have mayor roll in expression of supplemented rumen protected methionine. KIJORA et al (2002) in their research stated strong relationship between feed intake and protein content in the ration of dairy goats, thus aminoacid protection might have provided also higher RDP level in duodenum of dairy goats in our research. In addition, parity and live weight of animals could have had the impact on the production results.…”

“…The implement of the protected amino acids in dairy cows diet showed the improvements of the production of milk and milk proteins (OVERTON et al, 1996;PISULEWSKI and KOWALSKI, 1998). Although, the literature data are rather variable regarding the amino acid supplements and influence on the milk protein and milk fat synthesis in dairy cows it could be suspected the same effect on the dairy goats performance (OVERTON et al, 1996;OLIVEIRA et al, 2001;KIJORA et al, 2002;WANG et al, 2003). There were experimental model applied to show the gland amino acid uptake and partitioning in dairy goat and possible repercussion on the milk protein synthesis (LEE et al, 1999).…”

Abstract. The experiment was conducted on three farms of dairy goats. The experimental groups of animals were during the four months period supplemented with 5g Mepron®, (Degussa, Germany), daily. Milk yield, milk protein and milk fat content were recorded throughout the experiment. The milk production was statistically higher in the experimental group of animals on two farms, farm 1 and farm 3 in the first control period, a month after the application, whereas on farm 2, the higher milk production was present in the third and forth control period, two and three months after the application. During the experiment there was no statistically differences in milk protein and milk fat content between experimental and control groups on farm 1 and farm 2, whereas on farm 3 the milk fat content was statistically lower during the Mepron® supplementation. In conclusion, the higher milk production in the first control period on farm 1 and 3 with great probability referred to the influence of Mepron®. The higher milk production on farm 2 in the third and fourth control period coincided with introduction of alfalfa hay in daily ration, that may have enriched the amino acid supply.

“…Die Milchinhaltsstoffe stiegen hingegen mit späterer Lammzeit signifikant an. Ursache sind neben dem von LINZELL (1972) beschriebenen deutlichen Jahresrhythmus der Milchleistung, mit maximalen Leistungen in den Sommermonaten, auch Umwelteinflüsse, wie Fütterung (KIJORA et al, 2002), Temperatur und Weidegang (GALL, 2001). Das Ablammjahr hatte einen signifikanten Einfluss auf alle Milchleistungsmerkmale.…”

Abstract. Title of the paper: Influence of systematic environmental effects on milk performance traits in German Improved Fawn The objectives of this study were to analyse the influence of fixed effects on milk traits of German Improved Fawn. The analysis was based on 27,778 test day records of 1,848 German Improved Fawn with 3,574 lactation records. The milk records were sampled between 1988 and 2002 from 229 flocks in Lower Saxony, Saxony and Baden-Wuerttemberg. The average daily milk yield was 2.87 ± 1.20 kg with a fat content of 3.08 ± 0.54% and a protein content of 3.38 ± 0.95%. Somatic cell count (SCC) was transformed into somatic cell score (SCS). Mean SCS was 5.49 ± 1.93. The average lactation length was 234.1 ± 76.4 days. The analysis of variance showed a significant influence of lactation number, stage of lactation, year of lambing and month of lambing on all analysed milk production traits. Milk yield was highest in the fourth lactation number and fat as well as protein content in the 7th to 13th lactation number. Litter size had a significant influence on milk and fat yield and on fat and protein content. The region significantly influenced protein yield and fat and protein content of German Improved Fawn but had no effect on milk and protein yield and SCS. Animals from Baden-Wuerttemberg reached the highest milk protein content but the lowest milk fat content.
