Abstract

The purpose of this research was to determine and to assess the milk production of Holstein Friesian cows in Capita Farm based on its lactation period. The research was conducted on 29thSeptember – 28thOctober 2019. The materials used in the study were 59 FH dairy cows in the lactation period of 1-6 and lactation months of 1-10. The body weight was 497.71 ± 44.73 kg and the milk production was 14.43 ± 4.43 liters / day / head. The study was conducted by observation. The parameters observed were the lactation period and daily milk production. Afterward, the daily milk production was converted into milk production in one lactation period. The difference in milk production of one lactation period between the lactation periods was determined by the independent sample t test at level of 5%. The results of this research showed that the peak production in the 4th lactation period was 4458.26 liter/lactation, while the 1st, 2nd, 3th, 5th, 6th lactation periods were 3976.85; 4100.01; 4143.85; 3850.27; 2938.56 liter/lactation, respectively. The 6th lactation period was significantly lower than the others withproduction capability of 65.91% of the mature equivalent (ME). It was concluded that the Holstein Friesian dairy cows inCapita Farm has the highest production in the 4th lactation period, but there is a real difference in production when it enters the 6thperiod.

Abstract

This study aims to examine the effect of the storage time of milk at a temperature of -18? on the chemical, physical and microbiological content due to different storage times. The goat's milk studied was the milk of the Sannen Crossbreed of the Sapera goat. Twenty samples were taken from the milking results on the same day. The design used in this study was a completely randomized design (CRD) with five treatments and four replications. Samples were grouped according to treatment, namely 0d (control) and 10d, 20d, 30d, 40d; stored for 10, 20, 30 and 40 days, respectively. The milk storage process is carried out using a freezer at a temperature of -18?. The physicochemical and microbiological parameters observed were protein, fat, lactose, solid-non-fat (SNF), total solid (TS), specific gravity, pH, total plate count (TPC), and coliform. Evaluation of milk quality is based on the Indonesian National Standard (SNI) and Thai Agricultural Standard (TAS). The results showed that storage time did not significantly affect the components of fat, protein, lactose, total plate count, and coliform (p> 0.05). In milk stored for 40 days, there were differences in the values of SNF, TS, specific gravity, and pH compared to control (p<0.05). In terms of chemical, physical and microbiological quality, Sapera goat's milk stored at -18? for 40 days still complies with SNI and TAS. The process of storing and freezing milk can be an alternative for preservation to ensure the physical and chemical quality of Sapera goat's milk.

Abstract

Mayoritas masyarakat di Desa Tumbrep bermata pencahariaan sebagai petani dan peternak. Budidaya ternak yang dilakukan masih bersifat tradisional dan belum memiliki keterampilan mengolah limbah peternakan dengan baik. Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan skill kepada peternak di Desa Tumbrep untuk mengolah limbah peternakan menjadi biogas dan pupuk organik. Biogas yag dihasilkan diharapkan mampu menjadi energi alternatif bagi peternak dan slury hasil keluaran biogas dapat dimanfaatkan sebagai pupuk, sehingga mengurangi pencemaran lingkungan. Kegiatan ini dilaksanakan di Desa Tumbrep, kecamatan Bandar Kabupaten Batang Provinsi Jawa Tengah. Kegiatan pengabdian ini dilakukan dalam beberapa tahap yaitu sosialisasi tentang teknologi biogas, pembuatan biodigester, pengoperasion atau pengisian biodigester, uji pembakaran biogas dan monitoring dan evaluasi. Hasil kegiatan ini menunjukkan bahwa peserta kegiatan mempunyai respon yang baik terhadap program yang dilaksanakan. Biogas yang dihasilkan dari biodigester mencapai produksi yang cukup untuk digunakan menyalakan kompor untuk memasak peternak. Peternak dengan kepemilikan sapi sebanyak 5-6 ekor dapat direkomendasikan untuk penerapan pengolahan limbah peternakan menjadi biogas dengan biodigester berukuran 16 kubik.

Abstract

The aim of the study was to analyze the increase in body dimensions of post-weaning female Holstein Friesian (HF) calves fed with lactation cow concentrate with different levels of calf starter substitution. The material was 4 post-weaning female HF calves aged 4-5 months, with an average weight of 101.38 ± 14.21 kg. The feed consisted of elephant grass, calf starter (CS), and lactation cow concentrate (LCC). The study used a Latin square design, with 4 concentrate treatments, i.e. P1 (75% CS and 25% LCC), P2 (50% CS and 50% LCC), P3 (25% CS and 75% LCC), P4 (100% LCC); and 4 replications in 4 periods (each period in 1 month). The concentrate was given 1% BW in the dry matter; elephant grass and drinking water were provided in a measurable ad libitum. The research parameters were the increase in body dimensions (heart girth (HG), body length (BL), and withers height (WH)). The treatments had no significant effect (p>0.05) on the increase in body dimensions, were P1 (HG = 2.31 cm/month, BL = 4.75 cm/month, WH = 1.95 cm/month), P2 (HG = 4.23 cm/month, BL = 4.38 cm/month, WH = 2.23 cm/month), P3 (HG = 4.60 cm/month, BL = 4.38 cm/month, WH = 2.35 cm/month), P4 (HG = 4,10 cm/month, BL = 3.48 cm/month, WH = 2.18 cm/month). It was concluded that with sufficient quality forage feed, giving 100% LCC to post-weaning female HF calves could result in an increase in body dimensions that was relatively the same as the substitution of CS (25-75%) in LCC as concentrate feed.Keywords: post-weaning female HF calves, body dimensions, calf starter, lactation cow concentrate

Abstract

Penelitian bertujuan untuk mengkaji kualitas fisik susu segar pada peternakan sapi perah rakyat di Kecamatan Mijen, Kota Semarang. Penelitian di lakukan secara observasional pada 11 peternak yang menyebar dalam 3 Kelompok Tani Ternak (KTT) yaitu Sumber Rejeki 1 (SR1), Sumber Rejeki 2 (SR2), Rukun Makmur (RM). Kualitas fisik susu yang diamati meliputi berat jenis (BJ), pH, derajat keasaman, uji alkohol, uji didih dan total padatan terlarut. Hasil penelitian menunjukkan bahwa peternakan sapi perah rakyat di Kecamatan Mijen memiliki hasil uji fisik susu segar sebagai berikut : BJ 1,0258 g/ml; pH 6,37; derajat keasaman 7,23; total padatan terlarut 9,38% atau total solid 11,5%; uji alkohol negatif dan uji didih negatif.  Berat jenis, pH, uji alkohol dan uji didih tidak terdapat perbedaan yang signifikan (P0,05) pada ketiga KTT. Total padatan terlarut terdapat perbedaan yang signifikan (P0,05), yaitu SR 2 nyata lebih tinggi dari  SR 1 dan RM, sementara tidak terdapat perbedaan yang signifikan (P0,05) antara SR1 dengan RM. Simpulan yang diperoleh adalah susu segar pada peternakan sapi perah rakyat di Kecamatan Mijen sudah memenuhi syarat mutu SNI 3141.1.2011 ditinjau dari pH, derajat keasaman, uji alkohol, uji didih, total padatan terlarut, akan tetapi belum memenuhi kriteria pada berat jenis.

Abstract

This study aimed to examine the effects of storage on the physicochemical and microbiological quality of pasteurized goat milk. Milk from 40 crossbred Saanen goats, each in their third lactation period and DIM 60 (day in milk), was collected in the morning, resulting in a composite sample of 20 L. The milk was then pasteurized using the low-temperature long-time (LTLT) method. The experimental design was a completely randomized design with a factorial pattern. The treatments combined two factors: temperature and time. The temperature factor (T) consisted of T1 = room temperature (25–30°C), T2 = 15–20°C, T3 = 5–10°C, and T4 = -5–0°C. The time factor (V) consisted of V1 = 8 hours, V2 = 24 hours, and V3 = 72 hours, resulting in 12 treatment combinations (4x3) with three replications, yielding a total of 36 experimental units. The results showed a significant interaction (P<0.05) between temperature and storage time on the physicochemical and microbiological parameters of pasteurized goat milk. The total plate count (TPC) values for treatments T1V1, T1V2, and T1V3 were higher, whereas for treatments T4V1, T4V2, and T4V3, they were lower. The T0 treatment could only maintain milk quality up to 8 hours, T1 could maintain milk quality up to 24 hours, while the quality of milk in T3 and T4 treatments remained good even after 72 hours of storage. It is concluded that storage without refrigeration can maintain milk quality for up to 8 hours, while cooling with ice gel can maintain milk quality for up to 24 hours. For storing pasteurized goat milk for more than 24 hours or up to 72 hours, it is recommended to use a cooling device with a temperature below 10°C, such as a refrigerator or freezer.
