Penelitian ini bertujuan untuk mengetahui hubungan lama masa kering dengan produksi susu dan puncak laktasi pada sapi FH. Materi yang digunakan adalah data sekunder dari pencatatan recording 189 ekor sapi FH pada PT. Greenfields Indonesia di Desa Babadan Kecamatan Ngajum Kabupaten Malang. Analisis pengaruh lama masa kering terhadap produksi susu dan puncak laktasi dilakukan dengan menggunakan analisis regresi linier. Hasil analisis regresi menunjukkan bahwa hubungan lama masa kering terhadap produksi susu berpengaruh signifikan (P<0,05) dengan persamaan regresi Y = 28,31 – 1,26 X sedangkan dengan puncak laktasi menunjukkan hubungan yang tidak berpengaruh (P>0,05). Lama masa kering menentukan produksi susu pada sapi perah dengan masa kering yang ideal 55- 60 hari dimana semakin lama masa kering maka produksi susu akan menurun. Kata kunci : masa kering, produksi susu, regresi, sapi FH ABSTRACT The objective of this study was to evaluate the effect of dry period length on milk production and peak milk yield of the Friesian Holstein (FH) dairy cows. Data on milk production from 189 FH cows raised at PT. Greenfields Indonesia were collected and subjected to linier regression analysis. The results showed that dry period length significantly (P<0.05) on affected milk production with regression equation of Y = 28.31 – 1.26 X, but had no significant effect (P.0.05) on peak milk yield. The optimal length of dry period was observed between 55 and 60 days. Milk production decreased with the increasing length of dry period above 55-60 days. Key words : dry period, milk yield, regression, FH cows

Nutritional Strategy

Recently, there has been an interest in shortening the non-income-producing dry period (DP). Retrospective analysis of farm data and planned experiments both indicate about a 5 to 6% loss in milk yield during the subsequent lactation when the DP is reduced by approximately 30 d (Rastani et al., 2005). Additional milk produced during the extra 30 d of lactation can compensate for some of the loss in the subsequent lactation. There are, however, some advantages to reducing the dry period length, including increased income from milk in the current lactation, simplified management of dry cows through movement toward a one-group nutritional strategy, decreased metabolic disorders, and reduced strain on dry cow facilities. The aim of this study was to determine the effects of dry period length on milk production and composition in early lactating Holstein cows.

SummaryFenvalerate ear tags reduced fly loads on dry dairy cattle by 95% between July and September. Fly dislodging behaviour, such as ear flicks which correlated with numbers of Musca autumnalis on the face and stamps/kicks which correlated with numbers of Stomoxys calcitrans on the legs, was also significantly reduced. There was no significant difference between the tagged and untagged groups in the total time spent grazing each day. Milk yields were not statistically significantly different, but the tagged group showed a greater increase in milk yield between lactations, of 1·45 kg/cow daily in the first 12 weeks of the lactation.
