Diacylglycerol acyltransferase 1 (DGAT1) gene is one of the major genes that has an important role in milk fat synthesis. This research was aimed at to identifying genetic polymorphism of the DGAT1 gene by PCR-RFLP method and its association to milk fatty acid components. Animals studied were Holstein Friesian (HF) cattle from BBPTU Baturraden (123 cows) and BPPT SP Cikole (36 cows). The length of PCR product of the DGAT1gene was 411 bp. Genotyping resulted in two types of alleles, namely K (411 bp) and A (203 and 208 bp); and two genotypes, namely KK (411 bp) and AK (203, 208 and 411 bp). For both locations, genotype frequency of AK (0.75) was higher than KK (0.25). The allele frequency of K (0.64) was higher than A (0.36). Heterozygosity of HF cattles at both locations was relatively high (Ho>He). The DGAT1 gene of the observed HF cattle was polymorphic. Result showed that there was an association between the DGAT1 polymorphism with unsaturated fatty acids especially in nervonat acid. The AK cows had a significant effect on unsaturated fatty acid content of which having a higher nervonat content (0.05%) (P<0.05) than that of the KK cows (0.03%). From the results, it is concluded that the DGAT1 gene can be functioned as a marker of selection for milk fatty acids.

The aim of this research is to know the influence of the number of follicles produced per ovary on the quality of oocytes and the day length of developing blastocytes by in vitro fertilization (IVF) at 7-,8-, and 9-days. Material of the research is ovary of Fries Holland dairy cattle gathered from slaughterhouse. A number of 138 ovaries are grouped into four based on the number of follicles per ovary, including group I (≤5 follicles), group II (6-10 follicles), group III (11-20 follicles), and group IV (≥20 follicles). The result showed that the number of follicles per ovary are not significantly (P>0.05) influencing both on oocyte quality and the days length of forming blastocytes at 7-, 8-, and 9-days. Number of oocytes for grade A-B (percentage of the number of oocytes IVF per the number of oocytes obtained per ovary) for group I - IV consecutively is 83.5%, 91.3%, 97.1%, and 91.2%. The number of developing blastocytes (percentage the number of blastocytes per the number of oocytes) for group I - IV at 7-days consecutively is 5.19%, 5.56%, 5.45%, and 6.03%; at 8-days is 15.58%, 12.94 %, 13.64%, and 11.64%; at 9-days is 1818%, 8.96%, 8.18%, and 10.35%.

Lactoferrin (LTF) adalah gen pengontrol komponen protein susu dan memiliki karakteristik sebagai antimikrobial. LTF pada susu berfungsi untuk mencegah diare, sedangkan pada sapi laktasi untuk mencegah mastitis pada ambing. Mempertimbangkan peran penting dari gen LTF, maka perlu dilakukan peningkatan kadar LTF dalam susu melalui seleksi pada taraf DNA. Polymorfisme genetik dari gen LTF diidentifikasi pada sapi perah dan potong dengan metoda Polymerase Chain Reaction - Restricsion Fragment Length Polymorphism (PCR-RFLP), dengan enzim restriksi EcoRI. Genotyping dilakukan pada sapi perah Friesian Holstein (FH) total sejumlah 89 ekor, meliputi dari Balai Inseminasi Buatan Lembang (BIB Lembang) untuk 17 pejantan, Balai Besar IB Singosari (BBIB Singosari) untuk 32 pejantan, dan Balai embrio Transfer Cipelang (BET Cipelang) pada 40 dara. Genotyping dilakukan pula pada sapi potong dara berasal dari empat bangsa, meliputi Limousin (14 ekor), Angus (5 ekor), Simmental (13 ekor) dan Brahman (5 ekor) dari BET Cipelang. Gen LTF|EcoRI pada sapi perah dan potong pengamatan menghasilkan dua tipe alel, yaitu alel A dan B. Kedua jenis sapi tersebut menghasilkan hanya dua genotipe, yaitu genotipe AA dan AB, tanpa genotipe BB. Ini dapat menjadi hal yang baik karena genotipe AA dan AB dipertimbangkan berasosiasi dengan ketahan pada mastitis. Nilai-nilai dari heterozygositas observasi (Ho) dari gen ini lebih tinggi dibandingkan heterozigositas ekspektasi (He). Disimpulkan bahwa gen LTF|EcoRI memiliki variasi yang baik pada sapi perah dan sapi potong dari ketiga balai bibit nasional tersebut.

Information about genetic distances among populations (geographics) of local swamp buffalo is less published. Genetic distance analysis was done among seven local swamp buffalo populations trhough a morphological analysis. Female and male buffaloes were observed for a total number of 905 hds, originating from the Provices of NAD (100 hds), North Sumatera (51 hds), Banten (180 hds), Central Java (203 hds), South Kalimantan (121 hds), NTB (200 hds), dan South Sulawesi (50 hds). Genetic variation among buffalo populations was calculated by discriminant function of Mahalonobis distance. Genetic distance was estimated by MEGA program. Morphometric measurements of female buffalo in North Sumatera were larger (P < 0,01) than those of buffaloes in Banten, South Kalimantan, NAD and South Sulawesi. Morphometric measurements of male buffalo in South Sulawesi were larger than those of buffaloes in Central Java, Banten, and NAD. Chest width was the highest different morphometric factor (0.969). Buffalo from NTB had the highest similarity (95.0%), followed by buffaloes from North Sumatera (74.51%) and South Sulawesi (74.19%); while the lowest one was from South Sulawesi (38.02%) and Banten (49.44%). Morphological distribution map indicated existence of three local swamp buffalo groups. Grup 1 was presented by buffalo from NTB, distributed in the II and III quadrants. Group 2 was presented by buffaloes from five locations (North Sumatera, Central Java, South Kalimantan, South Sulawesi, and Banten), distrributed in I and II quadrants, and a smaller part distributed in III and IV quadrants. Group 3 was presented by buffaloes from NAD and a smaller part from South Kalimantan and Banten, distributed in IV quadrant. The lowest genetic distance was identified between buffaloes in NAD and South Kalimantan (0.348), while the highest one was between buffloes in Banten and South Kalimantan (1.883). Based on phenogram tree structure, the observed local swamp buffaloes could be classified into 3 cluster, namely: Cluster 1 from South Kalimantan, NAD and Banten; Cluster 2 from South Sulawesi, Central Java and North Sumatera, and Cluster 3 from NTB.

Correction factors as standard factor are needed to standardize internal environmental effects to evaluate genetic for desired traits of each breed, strain, or individual animal. Some dairy cattle scientists in warm (cold) and hot climate have made observing correction factors (CF) of internal environmental effects mainly for stages (days length) of lactation, calving age, milking ftequency, days open, and dry period for milk and its components (protein and fat). The correction factors should be done due to high variability on those parameters that occur natually eventhough dairy management have been kept well. Developing correction factors of calving age, days open, and days dry for milk production becomes main discussion in this paper. In Indonesia, correction factors of internal environmental effect for local Fries Holland dairy cattle need to be developed. The appropriate correction factors will be effective to eliminate the variation of milk yield caused by non-genetic effects. So the result of evaluation and selection could be expected to figure out genetic potencial of dairy cattle in producing milk. Key words: Milk yield, correction factors, and internal environment

Milk yield and milk quality are essential in determining the development of national dairy industry. Domestic fresh milk is largely produced by Holstein Friesian cows. There is a wide variation of the genetic ability of cows to produce milk or bulls to transmit milk, thus giving the opportunity for the improvement of milk production trait through selection. Milk yield as one of the quantitative traits, in the genetic evaluation, is estimated based on a breeding value. Breeding value can be estimated accurately through appropriate selection methods and by considering various non-genetic factors influencing milk production. This paper focuses the discussion on milk selection methods, which are very commonly done in dairy cattle. To produce superior dairy breeding cattle, selection for the bulls were done by progeny testing method, whereas selection for cows were commonly by individual selection method and their siblings. A number of internal environment factors should be considered in the genetic evaluation of milk production, through the development of appropiate correction factors, thereby increasing the accuracy of the estimated breeding values. The quality of milk especially milk protein contents, in the future, will get more attention from consumers. Therefore, selection should be directed also to improve milk protein components. The existence of major genes controlling on milk protein contents is expected to be the effective way in increasing milk protein yield in domestic HF cow. Selection of superior breeding dairy cattle in producing high milk protein contents is done through the identification of polymorphism of milk protein genes, providing casein and whey family genes. Key words: Holstein Friesian, selection, milk yield, milk protein

An intensive development in Indonesian dairy industry has expanded over two decades. During this period, the structure of the national dairy industry has progressed completely. The capacity of the national fresh milk production, however, has been able to supply only 35% of domestic milk demand. The milk domestic demand is predicted to be continous due to the increases in the national population and their welfare. Raising temperate dairy breed (Holstein-Friesian) under tropical climate has resulted many deteriorates in productivity. More inferiority has been found under a semi-intensive management at small dairy farms. The existence of various changes in the global trade regulation for agriculture commodities has been a considerable factor directly affecting the future development of the national dairy industry. Increasing efficiency of various determinant components of the national dairy industry is required to produce domestic fresh milk in a good quality at a competitive price. This paper is dealing with the status of various determined factors especially for dairy livestock components to improve the future national dairy industry prospectively, involving for the national dairy cattle population, domestic milk yield, productivity of dairy cattle, breeding system and supporting reproduction technology. More over, other essential factors providing for dairy institution as well as distribution and marketing domestic milk production are also described.

ABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh ketinggian tempat terhadap kondisi mikroklimat,termoregulasi dan produktivitas sapi Friesian-Holstein (FH). Penelitian dilakukan pada tiga lokasi dengan ketinggian berbeda, yaituPodok Ranggon (97mdpl), Ciawi (576mdpl), dan Lembang (1241mdpl). Sebanyak 63 sapi FH dalam kondisi laktasi normal digunakan dalam penelitian ini. Aspek lingkungan meliputi suhu udara, kelembaban relatif dan Temperature-Humidity Index di dicatat setiap 2 jam dari pukul 08.00 sampai 16.00 WIB. Parameter termoregulasi yang diamati terdiri atas suhu kulit (Ts),suhu rektal (Tr), suhu tubuh (Tb), denyut jantung (Hr),laju pernapasan (Rr), dan Heat Tolerance Coeficient (HTC).Berdasarkan nilai Ta, Rr dan THI, dataran rendah memberikan dampak cekaman panas sedang, dataran sedangdan tinggi memberikan dampak cekaman panas ringan pada sapi perah. Hasil menunjukkan bahwa sapi dataran rendah memiliki Nilai HTC, Tr, Ts dan Tb tertinggi (P<0,05) dan Hr yang terendah (P<0,05). Produksi susu di ketiga lokasi penelitian berbeda nyata (P<0,05), dengan produksi susu tertinggi di dataran tinggi (13,1±3,52 kg),dataran sedang (11,3±4,73 kg) dan dataran rendah (7,0±3,36 kg). Secara umum sapi FH di dataran rendah, sedang dan tinggi tercekam panas akibat kondisi lingkungan yang berada pada kondisi di luar zona nyamanselama musim kemarau, akan tetapi mampu beradaptasi terhadap kondisi tersebut. Kata kunci: ketinggian tempat, produktivitas, sapi perah, cekaman panas, termoregulasiABSTRACTThe purpose of this research was to determine altitude effect on microclimate, thermoregulation and productivity of Friesian Holstein. Research was conducted in different altitudes, i.e.: Pondok Ranggon (97m asl), Ciawi (576m asl), and Lembang (1241 m asl). A total of 63 FH cows in normal lactation were used in this study. Microclimate aspects observation includes environmental temperature (Ta), relative humidity (RH) and Temperature-Humidity Index (THI) were recorded every 2 hours from 08.00 to 16.00. The physiological responses measurements consisted of skin temperature (Ts), rectal temperature (Tr), body temperature (Tb), heart rate (Hr), respiratory rate (Rr) and Heat Tolerance Coeficient (HTC). Lowland environmental provide moderate heat stress, while the medium and highland impacts with mild stress. The results showed that lowland cows have highest HTC, Tr, Ts and Tb (P<0.05) and lowest Hr (P<0.05). Milk production in the different altitude was significantly different (P<0.05), with the highest milk yields in the highlands (13.1±3.52 kg), medium (11.3±4.73 kg) and lowland (7.0±3.36 kg). In general, HF dairy cows in low-, medium- and highland are exposed to climatic stress during dry season conditions, although they have the ability to adapt physiologically and cope with environmental stress.
