Abstract

Background: Consumers have the right to consume safe and healthy fresh milk. One of the factors that affect the productivity and quality of milk is the altitude of the location and environmental conditions around the farm. Objective: This research aimed to determine the differences in microbial quality and the somatic cell count (SCC) in milk between farms in the highlands (Cijeruk Farm, Bogor) and lowlands (Pondok Ranggon Farm, East Jakarta). Methods: This study observed the total plate count (TPC), the number of Staphylococcus aureus, and SCC. Microbial testing was carried out using the plate count method and the somatic cells count used the Breed method. The data were analyzed statistically using Mann-Whitney U and Chi-square. Results: The results showed that TPC, S. aureus, and SCC of milk from Pondok Ranggon located in the lowlands were higher than those of milk from Cijeruk located in the highlands. The average of TPC, S. aureus, and SCC in milk from Cijeruk were 1.6×104 ± 1.5×104 CFU/mL, 1.3×103 ± 4.2×103 CFU/mL, and 1,795,000 ± 1,838,791 cells/mL, respectively. The average of TPC, S. aureus, and SCC in milk from the Pondok Ranggon were 3.5×105 ± 1.0×106 CFU/mL, 1.7×105 ± 6.3×104 CFU/mL and 3,032,222 ± 4,348,654 cells/mL, respectively. This research showed that the location of the rearing area has relationship with S. aureus in milk (P<0.05). Conclusion: It was concluded that microbial status and the somatic cell count are influenced by differences in livestock areas.

Abstract

Circadian rhythm is the adaptation response of animals against light alteration that affects various behavioral and physiological responses. Bright light is a danger signal for nocturnal animals because it exposes them more to predators. This research aimed to study the changes in the behavior of rats during the partial solar eclipse (PSE) period. The PSE period occurred across Bogor, Indonesia, on 9 March 2016. The PSE started at 06.19 AM, peaked at 07.21 AM, and ended at 08.30 AM. The light level decreased since the early solar eclipse, then dropped significantly at the peak period. The activities of six mature male Sprague Dawley rats were measured using Opto-Varimex-5 Auto Track System during the PSE period. The measurements were repeated one day after the PSE period as the non-PSE period. There were significant differences (P<0.05) in stereotypic time, burst of stereotypic movement, and horizontal count in the early, peak, and end periods of the PSE period compared with the values at the same time of the non-PSE period. The activities of rats changed during the PSE period. Rats did not rest as in their normal nocturnal behavior during darkness but were more active and stressed because of the rapid change in light level during the PSE period.
