dc.description.abstract | U radu je prikazana analiza učestalosti intervala između dva osemenjavanja u dva godišnja perioda, od 1. 4. 2001. do 31. 3. 2003. godine na farmi sa 500 crno-belih holštajn-frizijskih krava, sa proizvodnjom mleka od 5500 do 6000 kg mleka. Histogramima su predstavljeni ciklusi od po mesec i po dana sa polnim ciklusima kod steonih, nesteonih i isključenih krava. Normalni i višestruki polni ciklusi ukazuju na greške u otkrivanju estrusa, kod 26,70 posto / 22,73 posto i kod 33,25 posto / 33,77 posto krava, u prvom / drugom analiziranom periodu. Skraćeni i produženi polni ciklusi zabeleženi su kod 12,22 posto i 4,34 posto, odnosno kod 10,07 posto i 7,36 posto krava i junica, a predstavljaju indikator poreme}aja u ishrani i držanju, odnosno pokazatelj su povećanog stepena embrionalnog mortaliteta. Poremećeni polni ciklusi su ustanovljeni kod 41,31 posto i 43,10 posto krava i junica i kumulacija su ostalih činilaca stadnog steriliteta. Planskim radom na prevenciji poremećaja funkcije jajnika i dobrom evidencijom, postiže se bolja plodnost zapata. | sr |
dc.description.abstract | The frequency of interestrus intervals between two inseminations during two annual period, from 1. 4. 2001 - 31. 3. 2003, on a farm with 500 Holstein-Frisian cows and milk production of 5500-6000 kg was analyzed. Periods of 1½ months of estrus cycles were presented by histograms for pregnant, nonpregnant and culled cows. Normal and multiple cycles indicate estrus detection errors, and were recorded in 26.70% / 22.73% and 33.25% / 33.77% cows, in the first and second analysed periods, respectively. Short and prolonged estrus cycles were noted in 12.22% / 4.34%, and 10.07% / 7.36% cows, in the first and second analysed periods respectively, and indicate nutritional disturbances and embryonal mortality. Disturbed estrus periods were found in 41.31% and 43.10% cows and heifers and were a consequence of other cumulate factors in herd sterility. Herd fertility improvement may be achieved with systematic work on prevention of ovarial disfunction and proper records management | en |
