Abstract

ABSTRAKPenelitian ini membandingkan tingkat kontaminasi bakteri pada susu segar yang dianalisis dengan uji reduktase, uji alkohol, kadar asam, dan standard plate count (SPC). Susu segar didapatkan dari lokasi peternakan, tempat pengumpulan susu (TPS) dan Koperasi Unit Desa (KUD). Hasil dari seluruh sampel susu yang didapat jumlah bakteri dalam susu melebihi SNI  3141.1: 2011. Sampel susu milik KUD adalah yang paling tinggi ( P < 0,05) diantara sampel susu yang lain dan tidak terdapat perbedaan antara jumlah bakteri antara peternak dan TPS. Meskipun jumlah bakteri melebihi standar SNI, rata – rata waktu reduktase diatas 8 jam, yang diindikasikan bahwa susu tersebut dalam kualitas yang baik. Jumlah bakteri akan meningkat ketika dibawa dari peternakan sampai ke KUD. Meskipun beberapa sampel terdapat hasil positif dalam uji alkohol, kadar asam dalam semua sampel masih dalam standar SNI. Kesimpulannya adalah peternak dan pemerintah harus memperhatikan higiene pemerahan, penanganan dan perlunya rantai dingin untuk memperlambat pertumbuhan bakteri. Kata kunci: jumlah bakteri; kontaminasi; susu segar; kualitas ABSTRACT This research was conducted to determine the level of bacterial contamination in raw milk as analyzed by the reductation test, alcohol test, total acid and standard plate count. The raw milk samples were collected from dairy farm, milk collection centre (MCC) and dairy cooperative. Results indicated that the bacterial count in all of milk samples were higher than SNI 3141.1:2001 standard. The dairy cooperative milk sample had the highest (P<0.05) bacterial count among the samples and there is no different (P>0.05) in the bacterial count between the dairy farm and MCC . Although the bacterial counts were above the SNI standard, however, the average of reductation time were above 8 hours, indicating good quality of raw milk. The number of bacteria increase when the shipping time from farm to dairy cooperative increased. Although some of the samples were positive in the alcohol test, the acid concentrations in all samples were in the range of SNI standard. In conclution, farmers and government should pay attention to milking hygiene, handling and cold chain to prevent the bacterial contamination in raw milk.Keywords: bacterial count; contamination; raw milk; quality

Abstract

ABSTRAK Penelitian dilakukan untuk mengkaji hubungan konsumsi serat kasar (SK) terhadap produksi susu dan kandungan lemak susu sapi perah. Materi yang digunakan adalah 30 ekor sapi perah laktasi. Kadar lemak susu dianalisis menggunakan analisis gerber, sedangkan kadar SK dianalisis menggunakan analisis proksimat. Data dianalisis secara korelasi untuk mengetahui besar kecilnya hubungan variabel bebas dan variabel terikat sertaanalisis regresi non linier kuadratik untuk mengetahui hubungan dari variabel-variabel.Hasil penelitian menunjukkan konsumsi SK rata-rata sebesar 5,99 kg/ekor, produksi susu rata-rata sebesar 10,95 kg/ekor, kandungan lemak susu 0,33 kg/ekor. Koefisien hubungan konsumsi SK pakan terhadap  produksi susu sapi perah rendah (r=0,275), dengan koefisien determinasi (R2=0,076)dan persamaan y = - 0,208x2 + 3,026x +0,828. Hubungan konsumsi SK pakan terhadap lemak susu sapi perah adalah sangat rendah (r=0,190), dengan koefisien determinasi (R2=0,036) dan persamaan y = - 0,005x2 + 0,070 x +0,086. Dapat disimpulkan bahwa hubungan antara konsumsi SK terhadap produksi susu dan lemak susu mengikuti kurva quadratik, berarti peningkatan konsumsi SK tidak menyebabkan peningkatan produksi susu dan lemak susu secara linier.Kata kunci : serat kasar; produksi susu; lemak susu; sapi perah ABSTRACT The research was done to evaluate the correlation between crude fiber intake with total milk production and milk fat by using a total of 30 dairy cattle. The concentrations of milk fat were analyzed using Gerber method, while crude fiber in the diets were analyzed using proximate analysis. The data analyzed by corellation method to find relationship value of independent variabel and dependent variabel, the non linier quadratic regression was used to analyze the data. The results showed that the average crude fiber intake was 5.99 kg/d which give total milk production of 10.95 kg/d, with milk fat content of 0.33kg/d. Correlation coefficient between crude fiber intake and total milk production was low (r=0.275), as well as the determinant coefficient(R2=0.076)with these equation y = - 0.208x2 + 3.026x + 0.828. Correlation coeficient (r) between crude fiber intake and milk fat content were very low (r=0.190), and the determinant coefficient (R2=0.036) with these equation y = - 0.005x2 + 0.070x + 0.086. In conclusion, the correlation between crude fiber intake, milk production and milk fat were followed the quadratic regression. It was suggested that increasing crude fiber intake did not increase milk production and milk fat.Keyword : crude fiber; milk production; milk fat; dairy cattle

Abstract

The purpose of this experiment was to investigate the main source of bacteria contamination in milk at smallholder dairy farmers. The research was conducted at Margo Rukun dairy farm group in Semarang regency. Samples were milk and possible bacteria contamination sources during milking process such as: milk bucket swab, cow teat skin swab, farmer’s hand swab, water used during milking and napkin for wiping the udder (cutted at 1x1 cm square). Observed parameter was total number of bacteria using total plate count (TPC) method. The data were analyzed by t-test and linear regression analysis. The result showed that the total bacteria in milk were 320.143 CFU/ml. Total bacteria in the bucket (320.143 CFU/ml) was higher (p<0.05) than that in the water (149.227 CFU/ml). However, total bacteria in the water did not differ with the total bacteria in the teat skin (109.833 CFU/ml). Total bacteria in the teat skin were higher (p<0.05) than that in the napkin (96.750 CFU/ml) and in the farmer’s hands (33.380 CFU/ml). Highest coeficient correlation (r=0.384) was found between total bacteria in milk and total bacteria in milk bucket, indicating that the milk bucket gave the highest contribution to bacteria contamination in milk. Keywords: milk, bacteria, contamination, milking

Abstract

The aim of this research is to determine the effect of teat dipping of Ettawa crossbred goat using babadotan leaves (Ageratum conyzoides Linn.) extract on the number of Staphylococcus aureusin milk. The udder inflammation degree also was determined using California Mastitis Test (CMT). The treatments were post milking teat dipping using antiseptic solutions containing 1%, 3%, and 5% of babadotan leaves extract (T1, T2 and T3, respectively). Milk samples were collected at before treatment (H0) and on the day 3, 6 and 9 day of the treatments (H3, H6 and H9, respectively). Commercially antiseptic povidone iodine was used as positive control (K+). Experimental research design was completely randomized design (CRD) split plot types, with the different extract concentration as the main plot and the day of treatment as subplot. CMT scores was analyzed using Kruskal-Wallis test. The results showed that babadotan leaves extract 5% had the same effectiveness (p>0,05) with povidone iodine to reduce the number of Staphylococcus aureusin milk. All extract concentrations (1%, 3% and 5%) had the same effectiveness (H>c0,05(3)) to decrease the CMT scores by postmilking teat dip treatments for 9 days. Keywords:Teat dipping, Ageratum conyzoides (L)., Staphylococcus aureus, CMT score

Abstract

Goat management in rural areas is still commonly done traditionally with little regard for health factors. One factor is the presence of parasitic worms in the goat's digestive tract which causes disturbed growth. The research aims to evaluate the effect of the addition of turmeric and multinutrient block plus (MNBP) in eliminating endoparasites and increasing feed intake of Jawarandu goats. The material used was 12 male Jawarandu goats weighing an average of 20 kg. A completely randomized design was used in this study with 4 treatments and 3 replications. Treatment T0: basal ration + MNBP; T1: T0 + 1% turmeric; T2: T0 + 3% turmeric; T3: T0 + 5% turmeric. The parameters observed were feed intake, weight gain, number of endoparasites and total eggs per gram of feces. Data analysis using analysis of variance significance level of 5% to determine the effect of treatment. If there is a treatment effect, it is followed by Duncan's multiple range test. The results showed a decrease in the number of endoparasites. The best treatment to induce an antibody system is T2 treatment, namely the addition of turmeric with a level of 3%. Feed intake was not significantly increasing although improving body weight gain in T2 and T3. The conclusion of the study is that the administration of MNBP and turmeric with a level of 5% has not been able to eliminate all endoparasites until the 28th day. MNBP and turmeric are useful as natural antioxidants. Increased level of turmeric can increase weight gain and immune system of goats.

Abstract

This study aimed primarily to investigate the effect of Zn-Proteinate (Zn-Prot) supplementation on in vitro rumen digestibility and rumen fermentation. This research used a completely randomized design with four treatments and four replicates. The experimental treatment was the supplementation of various levels of Zn-Prot (0; 12.5 ppm; 25 ppm, and 37.5 ppm) on a dry matter basis. Parameters determined were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), partial volatile fatty acid (VFA) (acetate, propionate, and butyrate), A/P ratio, CH4, and the efficiency of the conversion hexose to VFA. Data were analyzed using ANOVA. The results showed that goats fed with a diet supplemented with 25 ppm Zn-Prot had the highest IVDMD and IVOMD values. There was no significant effect on the VFA and CH4 concentrations, A/P ratio, and the efficiency of the hexose-VFA conversion within treatment groups. In conclusion, supplementing 25 ppm of Zn-Prot into the diet of dairy goat increase the dry matter and organic matter digestibility.
