Abstract

The aim of this research was to study the tendency of population distribution of Friesian Holstein (FH) cows and to create a population distribution map of FH cattle in Banyumas, Semarang, Boyolali, and Sleman regencies. Thisresearch was conducted from November 2007 to June 2008. Data collected were those of FH cows population from 2002 to 2006 in Banyumas, Semarang, Boyolali and Sleman Regencies and the production of crosscut grass, field grassand straw from agriculture waste in 2006 in the respective regencies. The result was the model of map of population distribution FH cattle in Banyumas, Semarang, Boyolali and Sleman Regencies. Structure of population of FH cattle inthe year 2006 pursuant to percentage sum up the bull calf, heifer calf, young bull, heifer, bull, cow in Banyumas Regency were 8.25, 13.32, 0.00, 8.86, 0.00, and 69.57%, Semarang Regency were 8.99, 13.00, 7.01, 16.00, 11.00, and44.00%, Boyolali was 9.00, 13.00, 7.00, 16.00, 11.00, and 44.00%, and Sleman Regency were 15.98, 1.58, 20.57, 0.72, and 47.39%. Population growth of FH cattle from 2002 to 2006 in Banyumas, Semarang, Boyolali and Sleman were –4.76, 3.52, 0.93, and 8.99% respectively. The produce of crosscut grass, field grass and straw from agriculture waste pursuant to value of Dry Matter (DM), Crude Protein (CP) and Total Digestible Nutrients (TDN) to requirement ofpursuant to amount of herbivore livestock with Animal Unit (AU) base in 2006 only Banyumas Regency which was still over supply while Semarang, Boyolali, and Sleman Regencies were found insufficient. The dynamics of requirementand availability of DM, CP and TDN from 2007 to 2011 in Banyumas Regency was over supply DM and TDN but insuffiency CP, Semarang Regency was insuffiency DM, CP and TDN, Boyolali Regency was over supply DM but insuffiency CP and TDN, Sleman was over supply DM but insuffiency CP and TDN from 2007 to 2008 and other years insuffiency DM, CP and TDN.

Abstract

The objective of this study was to estimate potential genetic of Friesian Holstein at Taurus Dairy Farm, Cicurug, Sukabumi. Data observed were secondary data of milk yield, calving interval, service per conception, age at first calving, and length of lactation records of cows that have been experiencing one or more lactation since year 2003 to 2009, then were standardized based on milk yield by using correction factor 305 days of lactation period and mature equivalent (ME). Production trait (milk yield), reproduction traits (CI, S/C, length of lactation, and age at first calving) were analyzed by descriptive statistic. Data were analyzed by paternal half-sib correlation and nested method to get heritability, while the repeatability value were obtained by interclass and intraclass correlation method. Heritability and repeatability value then was used to count most probable producing ability (MPPA) and estimated real producing ability value and estimated transmitting ability (ETA) and breeding value (NP) of dairy cows. Estimates of heritability of milk yield by using nested are 0.287±0.135 (h2s), 0.310±0.154 (h2d), and 0.299±0.103 (h2(d+s)), and paternal half-sib correlation method was 0.63±0.23. Estimates of CI heritability with paternal half-sib method was 0.46±0.23, and values obtained using nested were 0.038±0.106 (h2s), 0.733±0.231 (h2d), 0.385±0.117 (h2(d+s)). Estimated heritability of S/Cwith paternal half-sib method was 0.001±0.110 and using nested method are -0.022±0.043 (h2s), 0.098±0.133 (h2d), 0.038±0.072 (h2(d+s)). Estimated value of milk yield repeatability with interclass correlation was 0.43±0.1 and intraclass correlation was 0.15±0.05. CI repeatability value with interclass correlation method was 0.00±0.09 and intraclass correlation was 0.19±0.07. S/C repeatability value with interclass correlation method was 0.12±0.15 and intraclass correlation was 0.02±0.05. Based on the calculation, the highest five ranks on the estimated relative value of MPPA and ERPA from 147 holstein friesian dairy cows with interclass repeatability method and 279 Friesian Holsteindairycows with intraclass method were 1966, 1941, 2180, 2087, and 2248. Database, Kimball, Beam, Doeboy, Paul, Varlour and Cassela get the highest rank, based on the estimated value of ETA and NP for 40 bulls using paternal half-sib heritability method and 38 bulls using nested heritability method.(Keywords: Friesian Holstein dairy cows, Milk yield, Reproduction traits, Genetic parameter)

Abstract

Penelitian ini bertujuan untuk mengetahui faktor pakan dan tipe usaha yang berpengaruh terhadap produktivitas sapi perah, membandingkan profitabilitas usaha sapi perah rakyat dan perusahaan yang diukur berdasarkan produksi susu per ekor sapi laktasi, dan menduga pengaruh adanya perbaikan parameter produksi terhadap profitabilitas. Lokasi peternakan sapi perah rakyat di Yogyakarta, dan Perusahaan PT. Lembah Hijau Multifarm Sukoharjo, yang keduanya terletak di dataran rendah. Sampel sebanyak 30 ekor sapi perah laktasi diambil  secara purposive dan proporsional dari setiap lokasi. Pengambilan data melalui survei yaitu wawancara kepada peternak dan pemantauan langsung terhadap sapi sampel, untuk mengetahui pengaruh faktor pakan dan tipe usaha terhadap produktivitas sapi perah digunakan analisis regresi model fungsi produksi Cobb Douglas dengan metode OLS. Hasil analisis regresi menunjukkan bahwa secara bersama – sama total digestible nutrient (TDN) pakan hijauan, pakan konsentrat, dan tipe usaha berpengaruh nyata terhadap produktivitas sapi perah (R2 = 0,47). Secara parsial, TDN pakan hijauan dan pakan konsentrat berpengaruh signifikan (P<0,01) dan tipe usaha (P<0,05) terhadap produktivitas sapi perah. Indeks gross margin pada peternak rakyat lebih besar dari perusahaan, sedangkan indeks profit margin sebaliknya. Perbaikan parameter teknis yaitu memperpendek jarak beranak sampai 12 bulan dapat memperbaiki profitabilitas usaha pada peternakan sapi perah rakyat sebesar 6,55% dan pada perusahaan sebesar 19,48%, memperkecil mortalitas anak 0% dapat memperbaiki profitabilitas usaha pada peternakan sapi perah rakyat sebesar 1,55%. Perbaikan parameter ekonomis berupa peningkatan harga susu Rp6.000,00/liter dapat memperbaiki profitabilitas usaha pada peternakan sapi perah rakyat sebesar 113,96% dan perusahaan sebesar 109,98%, peningkatan harga feses Rp350,00/kg dapat memperbaiki profitabilitas usaha pada peternakan sapi perah rakyat sebesar 48,96%.(Kata kunci: Peternakan sapi perah rakyat, Perusahaan, Produktivitas, Indeks profitabilitas)
