Abstract

The study aimed to describe lactation characteristic of Etawah Crossed Breed goats raised under intensive management. The study located in BBPTU HPT Baturraden, Purwokerto, used 27 female pregnant goats, at 24 to 27 months old. The goats were managed followed standard operating procedure of the research institute. The data consisted of body size and body weight, colostrum and milk yield, lactation period and reproductive performance. The results showed the average of daily milk yield, lactation period, total milk and colostrum production in first lactation were 960±340 mL/day, 157±41 days, 114,720±68,900 mL and 415±240 mL/day. The proportion of monthly milk production from initial lactation to dry off were 21.27, 22.17, 20.18, 17.29, 12.52, 9.13, and 5.65% of total lactation yield, respectively. Peak production ranged from first to second months of lactation, the highest was in the week 4th, averaged of 1080 mL/day. Production persistency was 66.39%. The rate of increase toward peak was 5.60%/week and rate of decline from peak was -3.92% of milk yield in the previous week. Trend equation of lactation curve was Y = 8412.7 –233.65 x. Means period of postpartum mating, service per conception and body condition score were 88.7±39.2 days, 1.2 and 3.45, respectively. There was no correlation between postpartum mating, body condition score and milk production. The study concluded that Etawah Crossed Breed goat under intensive management had short lactation period, early peak production, low persistency. The dry period was estimated 3 months and pregnancy occurred after peak production.

Abstract

This study aimed to evaluate the body weight (BW), morphometry, and physiological status of Etawah Crossbred Doeling (ECD) under different farms management. This study was performed in two farms, Garage (Tlogoadi village, Mlati subdistrict) and Bumiku Hijau (Margomulyo village, Seyegan subdistrict), both located in Yogyakarta and each farm used 6 ECD as the replications (12 animals in total). Parameters of the study consist of body weight (BW), morphometry (chest girth, hip height, body length, chest depth, ear length, ear width, and withers height), physiological status (respiration, pulse, and rectal temperature). The parameter was measured weekly for four consecutive weeks of observation. The results showed that the difference in farm management between Garage and Bumiku Hijau influenced on the BW, morphometry, and physiological status of ECD. The study showed that the BW and all morphometry from the Garage farm was higher than Bumiku Hijau farm (P<0.05). However, the physiological status (except for rectal temperature) from Garage farm was lower than Bumiku Hijau farm (P<0.05). It can be concluded that Garage farm implemented better good farming practices compared to Bumiku Hijau farm.

Abstract

Cheese coagulants from plant origin have emerged as promising alternatives to animal rennet in cheese production. Among them, latex from Ficus carica L. has shown potential as a natural milk-clotting agent for goat cheese production. This study aims to determine the optimal incubation time and fig tree latex extract concentration on the quality of goat cheese. The optimization of the production process of the goat cheese was carried out using Response Surface Methodology (RSM) with Central Composite Design (CCD). The independent variables were the concentration of the Ficus carica L. latex extract (0.2-0.5 mL/100 mL of milk) and the time of incubation (60-120 min). The goal was to achieve maximum protein content (%), ash content (%), and calcium content (%). The results of this study showed that the Ficus carica L. latex extract used in the study could coagulate milk with a strength of 354.69 MCU and a dominant protein molecular weight of about 20 kDa. The optimization results using RSM method with CCD design showed that the goat cheese was produced optimally in 0.5 mL/100 mL of milk for the concentration of Ficus carica L. latex extract, with 120 min incubation time. These optimal conditions resulted in a cheese with protein content of 18.56%, ash content of 2.32%, calcium content of 803.93 mg/100g, and desirability level of 0.93.

Abstract

Butter is a dairy product that is susceptible to oxidation, which causes a rancid taste and a short shelf life. The quality of the butter depends on the quality of milk. The aim of the study is to determine the quality of butter made from goat and cow reared by small-scale farmers in Yogyakarta with the traditional manufacturing process. The milk of Saanen-Peranakan Ettawa (Sapera)  goats and Fresian Holstein were taken from farmers in Sleman district, Yogyakarta, Indonesia. Butters were sampled after 0, 15, 30 days storage. This study used the Nested Design method , namely the nested quality of butter in the type of milk. The result showed that butter made from cow milk produced a higher fat content compared to goat milk butter (P<0.05), namely 85.29 ± 0.04% and 80.10 ± 0.27%. The acid value increased while pH value was decreased during storage (P<0.05). There was no increase in peroxide value in cow butter but there was an increase in goat butter on day 0 to day 15 (P<0.05). It can be concluded that the goat and cow milk reared by small-scale farmers in Yogyakarta have good quality so it produced good quality butter which is still good for consumption until 30 days of storage in the refrigerator.
