20.500.12556/DKUM-16792 Analiza parametrov mlečnosti in plodnosti na govedorejski kmetiji Analysis of milk parameters and fertility on cattle farms Na kmetiji, izbrani za to raziskavo, se redno izvaja mesečna kontrola mlečnosti. Z analizo smo ugotovili, da je osnovni krmni obrok sestavljen neustrezno, saj v njem primanjkuje prebavljivih surovih beljakovin. Rezultati kontrol mlečnosti so nam pokazali nepravilnosti prehrane. Porazdelitev krav v polja glede razmerja med maščobo in beljakovinami v mleku (M/B) nam je pokazala, da je bilo decembra 2008 v optimalnem polju B2M/B več krav kot leta 2007. Tudi vsebnost sečnine je bila pri obroku leta 2008 višja kot leto poprej. Pri obračunu standardne laktacije med letoma 2007 in 2008 smo ugotovili, da med obravnavanima letoma ni statistično značilnih razlik. Primerjava med pasmami je pokazala, da se LS-pasma statistično razlikuje od ČB in KR v vsebnosti maščob v mleku (P < 0,05). Največja mlečnost je bila leta 2007 pri prvesnicah. Leta 2008 je bila najvišja mlečnost v tretji laktaciji. Rezultati plodnosti po obroku v letu 2008 so boljši kot pred obrokom v letu 2008. Dolžina cele laktacije je trajala v povprečju 374 dni. In the farm a regularly milk check is carried out. The analysis of feed was found to be inadequate because of the basic meal consistency, it lacks digestible crude protein. Milk recording results have shown us irregularities in the diet. Distribution of cows in a field on the relationship between fat and protein in milk (M / B) showed us that in December 2008, more cows were in the optimum field B2M/B than in 2007. The concentration of urea was higher in 2008 than in 2007. The accounting standard lactation between 2007 and 2008 has shown that during the two years there were no statistically significant differences. The comparison between breeds showed that the LS breed is statistically different from the CB and KR in the fat content of milk (P <0.05). The maximum yield in 2007 was with the first-calves. In 2008, the highest yield was in the third lactation. Fertility results after eating in 2008 are better than before the meal in 2008.
