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

Gliricidia maculata which has long been used as a forage for animal feed may contain a variety of glucogenic amino acids variants. The objective of this study was to identify the glucogenic amino acids content in Gliricidia maculata as an alternative source of energy for high-yielding periparturient dairy cows. The samples were the edible portion of plants, harvested randomly at the optimal cutting age (80 days), from the feed plant collection garden of The Faculty of Animal Science, Universitas Gadjah Mada. Lyophilization was carried out by drying the samples at 55°C for 3 x 24 hours continouesly in a Sanyo Drying Oven MOV-112. Pulverization was done by the Foss Tecator CyclotecTM 1093 Sample Mill with 300 mesh (1 mm screen). The hydrolysis of amino acid was carried out using HCl solution while amino acid derivatization used O-phtalaldehyde (OPA) solution. Separation, determination, and quantification of amino acid were carried out by an analytical method in gradient elution using the Thermo ScientificTM DionexTM UltiMateTM 3000 UHPLC Systems with Rapid Separation Fluorescence Detector. Result showed there were at least fourteen kinds of amino acids identified from the samples, i.e.: aspartic acid, glutamic acid, serine, histidine, glycine, arginine, alanine, tyrosin, methionine, valine, phenylalanine, isoleucine, leucine and lysine. Gliricidia maculata contains 1349 ppm glucogenic amino acids, 412.7 ppm ketogenic amino acids and 444.7 ppm glucogenic and ketogenic amino acids. Moreover, there were three types of glucogenic amino acids with the highest concentration were serine (288.7 ppm), glutamic acid (245.5 ppm) and phenylalanine (197.1 ppm) respectively. Glucogenic amino acids can be used as an energy source for dairy cows through gluconeogenesis. This study suggests that Gliricidia maculata may use to supply the precursors of energy for high-yielding periparturient dairy cows to prevent ketosis.

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.
