Sebanyak 16 ekor sapi perah Fries Holland (PFH) dalam masa kering kandang di Peternakan INKOPPOL di Cijeruk Bogor, telah digunakan untuk mempelajari pengaruh injeksi bovine somatotropin (bST) dan suplementasi mineral logam seng (Zn) terhadap peningkatan volume produksi dan kualitas susu pada periode laktasi berikutnya. Pada penelitian ini sapi-sapi dibagi ke dalam dua kelompok dan menggunakan Rancangan Acak Kelompok 2x2. Kelompok pertama adalah sapi kontrol terdiri atas delapan ekor. Kelompok kedua disuntik dengan bST. Faktor pertama adalah penyuntikan dengan bST dua tingkat dosis, yaitu nol (kontrol) dan 250 mg per ekor per dua minggu. Sedangkan faktor kedua adalah suplementasi Seng ( Zn) dengan dua tingkat dosis, yakni: 35 ppm dan 75 ppm. Peubah yang diukur adalah: fa’ali hewan (frekuensi pernafasan dan suhu tubuh), kimia darah (hematokrit, hemoglobin, glukosa dan trigliserida), produksi susu, volume ambing, kualitas susu (jumlah bakteri susu, pH, komponen gizi: protein, lemak, laktosa dan karbohidrat ), sanitasi dan mastitis. Hasil penelitian menunjukkan bahwa Bovine somatotropin tidak meningkatkan frekuensi pernafasan, suhu tubuh dan kimia darah ( hematokrit, hemoglobin, glukosa dan trigliserida). Injeksi bovine somatotropin pada sapi perah dalam periode kering dapat memberi pengaruh yang nyata (signifikan) pada peningkatan produksi susu dan volume ambing. Terdapat interaksi antara bST dengan suplementasi seng pada produksi susu dan volume ambing. Injeksi bovine somatotropin dan suplementasi seng selama periode kering dapat meningkatkan produksi susu sampai 17-25 persen. Suplementasi seng yang dikombinasi dengan somatotropin, ternyata juga dapat mengurangi mastitis subklinis.Sixteen dry period dairy cows of the Fries Holland Breed in INKOPPOL Cijeruk, a highland in Bogor, were used to study the effect bovine somatotropin (bST) injection and zinc (Zn) supplementation during dry period on the improvement of milk yield and milk quality in the next lactation. The experimental cows were classified into two groups and assigned into a randomized block design with a 2x2 factorial arrangement of treatments. The first factor was somatotropin treatment consisting of two levels: without injection (control) and biweekly injection with 250 mg of somatotropin (bST) per head. The second factor was with zinc supplementation at 35 ppm and 75 ppm. Variables measured were the respiration frequency and rectal temperature, blood chemistry (hematocrit, hemoglobin glucose and triglyceride), milk yield, udder volume, milk quality (bacterial count, pH, nutrition: protein, fat, lactose, carbohydrate), sanitation, and mastitis. It was found that Bovine somatotropin did not significantly increase the respiration rate, rectal temperature and blood chemistry (hematocrit, hemoglobin, glucose and triglyceride). However, Bovine somatotropin injection in the dry period significantly increased milk production and udder volume. There was an interaction between bST dan zinc supplementation on milk production and udder volume. Bovine somatotropin injection biweekly and supplementation in dry period increased milk production by 17-25 percents. Supplementation of zinc in combination with somatotropin reduced subclinical incident of mastitis in the dry period.

This study aims to see the extent of influence of oxytocin hormone induction on the nutritional composition of milk in the Etawah CrossbredÂ goat. This research was conducted in December 2018 in Syiah Kuala District, Banda Aceh, Indonesia. The examined parameters were the levels of fat, nonfat dry matter (BKTL), protein content, lactose content and milk density. The research used 18 Etawah goats and oxytocin hormone. A statistical unpaired t test indicated a highly significant influence (P <0.01) on the increase of milk fat injected with oxytocin hormone, i.e. 4.86% or 37.2% or higher than that without hormone injection. The milk density results showedÂ a significant effect (P <0.05) on the decrease in goat milk density (28.81% ) which was lower by 10.65% from that without hormone treatment. The level of nonfat dry matter (BKTL), protein content and lactose content had no effect (P> 0.05) in milk, i.e. 8.39%, 3.91% and 3.76%, respectively. In conclusion, hormone oxytocin injection had a highly significant effect on increasing milk fat levels and significantly affected the decrease in milk density but did not affect the level of nonfat dry matter (BKTL), lactose and protein.

Fermented milk is one of important source of human nutrition, but not every one able to digest it properly, which can cause lactose intolerance. One alternative solution is milk should be fermented. Lactose in milk is broken down into glucose and galactose by the starter culture activity and decrease the digestion problem. There are milk based syrup which is potential to be improved in Indonesia as diversification product of fermented milk. Research has been conducted in Milk Processed Laboratory, Agriculture Department, of Syiah Kuala University. The experiment divided in to two phase which were 1) to determine milk fementation process by different pecentage of bacteria and 2) making syrup by adding sugar in fermented milk. Completely Random Disigned (CRD) was used based on sugar and yoghurt ratio in several species of microflora. namely Lactobacillus bulgaricus, Lactobacillus acidophillus and Streptococcus thermophillus. Te result of the first phase showed that milk completely fermented by adding 5 percent of bacteria and significantly (p0,05)effect the pH, lactic acid level and unsignificantly effect fat and protein level. In the second phase showed that the best syrup performance is 50 percent fermented milk added with 5 percent sugar. The addition of different percentage of starter very significantly (P0,01) effect on pH, lactic acid level and also effect hedonic test. Furthermore, that treament given did not effect any of fat, protein, colour and aroma. In conclusion, percetage of sugar and starter addition will influence the flavor of fermented milk syrup

This study aimed to know the physiological response and milk production of Etawah Crossbreed (PE) goat injected with the hormone oxytocin. The mechanism of action of the oxytocin hormone in the body will suppress the production of the cortisol hormone, which causes livestock stress. For now, there are not many publications about the induction of oxytocin hormone in PE goats. In this research, the researchers will provide the latest information. The research material is 18 lactation PE goats divided into 2 groups, namely control and hormone treatment. This research is in the form of an experimental research design with a control group post-test only design. The design used is an independent t-test. Hormone injection is carried out intramuscular, as much as 1 ml with a dose of 10 IU. The parameters measured were milk production (ml), heart rate (times/minutes), and respiration frequency (times/minutes). Oxytocin injection had no significant effect (P>0.05). Still, it tended to increase the milk production of PE goats in the morning and evening with total milk production of 1103.65±145.72ml compared to without injection of 884.38±90.49ml in 1 day. Similarly, the injection of the hormone oxytocin did not affect the frequency of respiration in the morning and evening. However, it was different from the PE goats heart rate, which had a significant effect (P<0.01) in the morning. On the other side, there was no significant effect (P>0.05) in the afternoon. The indicators of stress in dairy cattle are respiration frequency and heart rate outside normal limits, affecting milk production. This study concluded that the induction of the oxytocin hormone did not affect milk production, and the cattle did not experience stress because the heart rate and respiration frequency were in the normal range due to the injection of the oxytocin hormone.

Ceker ayam merupakan salah satu produk sampingan (by product) yang dihasilkan dari Rumah Potong Ayam (RPA) yang kurang diminati masyarakat Aceh sebagai bahan makanan layaknya daerah-daerah lain di Indonesia, sehingga diperlukan upaya pemanfaatannya sebagai pakan tambahan bagi ternak. Tahap penelitian dimulai dari tahap persiapan, pemberian pakan dan tahap pengambilan data. Perlakuannya terdiri dari (kontrol tanpa penambahan tepung ceker ayam), (penambahan tepung ceker ayam sebanyak 2,5%), (penambahan tepung ceker ayam sebanyak 5%), (penambahan tepung ceker ayam sebanyak 7,5%). dan (penambahan tepung ceker ayam sebanyak 10%). Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) yang terdiri 5 perlakuan dengan 3 kelompok. Pengelompokannya berdasarkan berat badan dari tenak Kambing Peranakan Etawah. Parameter yang diamati ialah pengukuran bahan kering, kadar protein, kadar lemak, kadar laktosa dan pH susu kambing Peranakan Etawah. Hasil analisis sidik ragam pada penelitian memperlihatkan bahwa penambahan tepung ceker dalam ransum kambing Peranakan Etawah sangat berpengaruh nyata (P0,01) terhadap kadar bahan kering, kadar protein, kadar lemak dan kadar laktosa, namun tidak berpengaruh nyata (P0,05) terhadap pH.Efforts to improve the milk quality through the addition of chicken claw flour with different percentage on rations of etawah goat breedAbstract. The Goat of the Etawah Breed is one of the highest milk producers. To increase productivity and reduce production costs sought by feeding additives in the form of chicken claws. Chicken ceker is one of the by-products produced by Chicken Slaughterhouse (RPA) which is less attractive to the Acehnese as a food ingredient like other regions in Indonesia, so that the utilization of it is needed as an additional feed for livestock. The research phase starts from the preparation, feeding and data collection stages. The treatment consists of ( (control without addition of chicken claw flour), ( (addition of chicken claw flour as much as 2.5%), ( (addition of chicken claw flour as much as 5%), ( (addition of chicken claw flour as much as 7.5%). and R4 (addition of chicken claw flour as much as 10%). The research design used was Randomized Block Design (RBD) which consisted of 5 treatments with 3 groups. The grouping is based on the body weight of the Etawah Breed Goat cattle. The parameters observed were measurements of dry matter, protein content, fat content, lactose content and pH of milk of Etawah Breeds goats. The results of variance analysis in the study showed that the addition of chilli flour in the ration of Etawah Breeders goats was very significant (P 0.01) on the levels of dry matter, protein content, fat content and lactose content, but did not significantly influence (P 0.05) on pH.Abstract.

The purpose of this study was to determine the effect of soaking the skin with the enzyme bromelain on the quality and organoleptic of cowhide crackers. This research uses cowhide and bromelain enzyme (commercial). The bromelain enzyme treatments were: P1 = (control), P2 = (5%), P3 = (10%), P4 = (15%). The design of this study used a completely randomized design (CRD) consisting of 4 treatments and 4 replications and obtained 16 experimental units. The data were analyzed by Analysis of Variance (ANOVA) and if there is a difference between the treatments, the analysis will be continued with Duncan's multiple distance test. The results of variance showed that the bromelain enzyme immersion with different presentations for two hours showed a very significant effect (P 0.01) on the pH test, while the protein test showed no effect (P 0.05). The organoleptic test with bromelain enzyme immersion with different presentations showed no effect (P 0.05) on color, taste, and crispness. The results of the study concluded that soaking bromelain enzymes with different percentages for two hours did not cause differences in protein in beef skin crackers but could increase the pH value of skin crackers and could not cause differences in color, taste, and crunchiness of skin crackers.
