Abstract

One of the benefits of probiotics is their ability to synthesize conjugated linoleic acid (CLA) as a functional bioactive compound. The objective of this study is to identify CLA synthesized in milk fermented with the probiotic Lactobacillus casei strain AP and Lactobacillus casei strain AG as starter cultures. Fermented milk products were analyzed using gas chromatography-mass spectrometry (GC-MS) to characterize the CLA formed. The result of GC-MS in milk fermented using Lactobacillus casei strain AG was detection of a CLA compound with a retention time of 41.467, whereas in milk fermented using Lactobacillus casei strain AP, linoleic acid, but not CLA, was detected.

Abstract

This study was conducted to identify the food labeling profile in animal-based food products based on consumers’ age and gender, consumers’ preference of the information provided in the label, consumers’ behavior in reading the label, and consumers’ knowledge about food labeling. A total of 100 respondents participated in the study. The sampling was done by using judgmental sampling method with the following criteria: (1) respondent has bought animal-based food products within the last month of the study; (2) respondent’s age was over 18 years old. The data were analyzed descriptively and by using regression analysis. The results showed that female respondents and a group of 50 years or older respondents were used to read the food label frequently compared to other respondent groups. The type of information which considered as the most important was the expiration date, followed by product’s name, ingredients, halal status, nutritional value, product’s instruction for usage and its irregularities, net weight, and the producer’s name and address. This study also identified that the majority of the respondents, as many as 67%, already had good knowledge about food labels, while the other 32% had adequate knowledge, and only 1% of the respondents had a little knowledge about food labels. It can be concluded that consumers’ perception of the potential risks on animal-based food products affect their behaviour in reading the label (p<0.05) while consumers’ health condition and time availability to buy the products did not affect their behaviour in reading the label in animal based food products.

Abstract

This study was aimed to compare somatic cell count and milk production on dairy cattle after teat dipping post milking application. Samples collected from total of 121 quarters of dairy cattle in normal lactation period and identified as infected by subclinical mastitis. Subclinical mastitis examination was done by IPB Test Mastitis Test, somatic cell count calculation was done by Breed Method, and observation of milk production was done by calculating milk volume per quarter. Observations were performed during normal lactation periods of 12 weeks. Data were analyzed statistically using Mann-Whitney Test and unpaired t-test. The results showed that the number of somatic cells count in the treatment group with post milking teat dipping application was lower than in the control group and significantly different at week 11 (p = 0.039). Furthermore, the volume of milk production in the treatment group was higher than in the control group and significantly different in almost all weeks of observation (p<0.05). It was showed that post milking teat dipping application can prevent subclinical mastitis infection effectively, seen from low somatic cell count (below 400.000 cells/ml) and can maintain optimum milk production. So that, this application can increase the economic benefits for dairy farmers.

Abstract

The aim of this research is to understand the production characteristics of male bandicoot (Echymipera kalubu) and obtain basic morphometric information for cultivation and development of the animal. The research was done through the explorative method by using 30 random undomesticated adult male Echymipera kalubu obtained in Manokwari regency forest, West Papua. The morphometric characteristics of Echymipera kalubu in regards to the body weight and carcass weight are yet to be observed and standardized for practical use. The obtained estimator variables were analyzed by SPSS 24 for windows to calculate the multiple regression and coefficient of correlation value. The results of statistical analysis showed that there were 4 estimator variables that had positive correlations, which were body length (X1), hind legs length (X2), heart girth (X4), and cannon girth (X5). The obtained body weight regression formula was Y1 = -1367.355 + 33,912X1 + 7,095X2 + 89,745X4 – 14,494X5 with the coefficient of determination at 0.815. Moreover, the obtained carcass weight regression formula was Y2 = -1282,170 + 40,113X1 + 7,666X2 + 66,750X4 - 24,231X5 with the coefficient of determination at 0.794. The research concluded that the best estimator variable for body weight and carcass weight was the heart girth.

Abstract

This study aims to estimate the carrying capacity of oil palm plantations with the use of herbicides based on the forage availability for Bali cows. The research was performed in palm oil plantation owned by PTPN V Riau, from March 2016 until March 2017. The parameters observed were 1) Forage production that grows between palm trees at 6 weeks cutting age. The forage sample was taken from 5 point of 1x1m2, then subjected to proximate analysis. Data were analyzed with one-way random design, 2) Forage consumption; obtained by observation of 5 pregnant Bali cow and 7 non-pregnant for seven consecutive days 3). Estimated carrying capacity for Bali cows, obtained from the calculation of forage production (/ha/year) divided by forage consumption. The result of the research showed that 1). The production of dry matter (DM) forage in herbicide-treated areas was 689.55 kg/ha/year, not significantly different compared to untreated areas (622.33 kg/ha/year). Crude protein (CP) forage content of forage obtained from herbicide-treated area was significantly higher (p<0.05) than untreated area, whereas the total content of DM and total digestible nutrients (TDN) was not significantly different. DM consumption of pregnant Bali cow was on average 3.68±0.29 kg/head/day or 1,343.20±105.85 kg/head/year and non-pregnant 4.02±0.36 kg/head/day or 1,467.30±131.4 kg/head/year. The estimated carrying capacity on herbicide-treated (0.51 head of pregnant cow/ha), did not show any significant difference compared to untreated area (0.46 head/ha). For non-pregnant, the carrying capacity of herbicide-treated area (0.47 head/ha) was not different with non-treated area (0.42 head/ha). It was concluded that the use of herbicide on palm oil plantation had no effect on the carrying capacity of the Bali cow.

Abstract

High fat diet can result in the loss of nitrergic neurons in the myenteric plexus. The study aimed at finding out the effect of high fat diet on the adaptation of nitrergic nerve of rat intestine. It used 15 male rats (Rattus norvegicus) of a month of age with mean body weight of 53.73 gr. The rats were adapted for 7 days to individual cages with ad libitum feeding. After random adaptation, all of the rats were assigned to 3 groups of five rats, namely K-7, K-10, and K-13 groups. Feed and drinking water were given ad libitum. The treatment of the high fat diet lasted for 7 weeks. After the treatment, all of the rats were fasted for 12 hours and then killed. Subsequently, small intestine segments (duodenum, jejunum, and ileum) were taken. The intestinal segments were prepared by using NADPH-d histopathological technique to determine the morphometric changes of nitrergic myenteric neurons. During the treatment the rats were weighed every week and at the end of the study orbitalis vein blood measurement was carried out to see its glucose, cholesterol and cholecystokinin (CCK) plasma levels. The data of body weight, glucose, cholesterol, CCK levels, the total number of the nippergenic myenteric segments of the small intestine were statistically analyzed using Anova. The results of the study showed that the treatment of 7% to 13% fat diets for 7 weeks did not indicate any weight gain and any increase in cholescystokinin level, and any decrease in glucose level. However, it indicated significant increase in cholesterol level. The treatment of 10% and13% fat diets increased the total number of neurons in the jejunum and the ileum. Thus, it was concluded that the treatments of the high-fat diet of the rats (K-7, K-10, and K-13) for 7 weeks had significant effect on the adaptation of the neurons of the jejunum and the ileum.

Abstract

This research aimed to evaluate the effect of high quality feed supplement (HQFS) in growth performance of post-weaning calves. Twenty four calves post-weaning aged 6 months old, consisting of 12 males and 12 females, randomly divided into 2 groups, each group consisting of 6 calves. Grouping male and female calves fed control feed plus HQFS, was formulated from corn grain, corn gluten meal (CGM), pollard, soybean meal (SBM), wheat flour and agromix booster (treatment diet) as first group (treatment), and the second group was fed control feed without addition of HQFS (control). This study was conducted for 6 weeks. The variables observed included feed intake (dry matter, crude protein, and TDN), weight gain, feed conversion, feed cost per gain and body size (body length, chest girth, and withers height). The treatment was in factorial 2x2 in a Completely Randomized Design (CRD). Growth performance of post weaning calves were analyzed as repeated measures with feed (treatment and control) and sex (male and female) as factors.  Results showed that the CP consumption, ADG and chest girth of treatment group was higher than (P<0.01) than the control group (0.42 and 0.34 kg/d, 0.95 and 0.71 kg/d, and 12.41 and 8.25 cm). TDN consumption, feed conversion, and body length of the treatment group were higher (P<0.05) than the control group (3.08 and 2.57 kg/d, 3.64 and 4.86, and 8.12 and 5.95 cm). DM consumption, chest girth and feed cost per gain of treatment and control group were not significant (3.87 and 3.69 kg/d, 7.30 and 6.72 cm, and IDR 16,280.00 and IDR 19,167.00). There was no difference between the growth of post-weaning calves between the male and female groups. There was no interaction between feed type and sex of the post-weaning calves. The conclusion of this study was that post-weaning calves fed HQFS (20.2%) produced better growth performance than controls.
