Abstract

This study aimed to determine the effect of pro-bio addition in the feed to weight gain, feed consumption, and feed conversion of broilers. This study was carried out in the cage’s of the Animal Husbandry Study Program, Faculty of Agriculture, Timor University from September to November, 2018. A total 80 day-old broilers (DOC) were used in the study.The feed utilized were BR1, BR2 and pro-bio. The experiment was designed as a Complete Randomized Design (CRD) consisting of 4 treatments and 4 replications. The treatments consisted of P0 (commercial feed without probio), P1 (99,7% commercial feed +0.3% probio), P2 (99,5% commercial feed +0.5% probio) and P3 (99.3% commercial feed + 0,7% probio). The variables observed were weight gain, feed consumption, and feed conversion. The data of weight gain of P0, P1, P2 and P3 were 49,05; 52,53; 48,80 and 53,42 g/bird/day, respectively. The feed consumption were 134,74; 137,21; 138,16 and 139,52 g/bird/day, respectively. The feed conversion were 2,75; 2,62; 2,83 and 2,61, respectively. The results of the statistical analysis showed that the addition of pro-bio had a very significant effect (P<0.01) on feed consumption, whereas weight gain and feed conversion had not significant effect. It was concluded that the addition of probiotics in feed had no effect on weight gain, feed conversion but could have a significant effect on feed consumption.

Abstract

This research was conducted at Claretian Benlutu dairy farm, Batu Putih District, TTS Regency for one month. This research consisted of 2 stages, namely 1 month of nipple dyeing and the second stage of testing the sample in the laboratory. The purpose of this study was to determine the effect of the use of garlic extract (Allium sativum) as a natural ingredient in the nipple on the microbiological quality of fresh cow's milk. In this study used 16 nipples from 4 dairy cattle. The experimental design used was a Completely Randomized Design of 4 treatments and 3 replications, with the treatment being R0 = commercial antisep solution as a control, R1 = concentration of garlic extract 20%, R2 = concentration of garlic extract 25% and R3 = concentration of onion extract white 30%. The variables observed in this study were reductase time and total bacteria. The results showed that the use of garlic extract (Allium Sativum) had the same effect as the commercial antisep solution seen from the time of bacterial and total bacterial reductase (P> 0.05). This is because garlic has anti-bacterial allicin which can inhibit bacterial growth. It can be concluded that garlic extract has the same ability as a commercial antisep solution in inhibiting the bacteria that causes mastitis in the nipples of dairy cows. Microbiological test results of 2 variables of milk use of garlic extract with a concentration of 20% are very optimal in the use of dairy milk nipple dyes in addition to inhibiting bacteria also saves costs in making garlic extract.

In this study, fresh milk was used with different storage containers made from glass, plastic and commercial plastic. The experimental design used was a factorial completely randomized design with 4 x 3 treatments and 4 replications. The treatments consisted of W0 = a container made of glass, W1 = a container made of plastic, and W2 = a container made of Tupperware which was stored for 1 day (P0), 3 days (P1), 5 days (P2), and 7 days (P3). The variables observed were an organoleptic test, acidity titration, pH, and TPC test. The results of the ANOVA variety showed that the storage container and storage time had a very significant effect (P <0.05) on the degree of acidity by tetrimetric, pH, and TPC, the interaction of storage containers, and storage time on the degree of acidity and TPC was very significant (P <0, 05) but the interaction for pH was not significant (P> 0.05). The conclusion from this study is that the type of container made from plastic bottles with a storage time of 1 day is better than containers made from glass bottles and tupperware. This can be seen from the results of the organoleptic test, acidity titration, pH, and TPC test.
