Abstract

This study aimed to evaluate the effect of breeds and bulls ages on semen volume, sperm concentration, total number sperm, progressive motility, and sperm abnormalities of semen bull. The data used in the form of semen quality data from the Singosari National Artificial Insemination Center from the period 2021 to 2022. The bulls used each returned 4 bali, simmental and limousin. With age categories 3-4 years, 5-6 years, 7-8 years and 9-10 years. The research design used was a completely randomized factorial design. Data sperm quality were analyzed by general linear model method followed by LS mean. Sperm quality studied showed an interaction (P<0.05) between breed and age on the volume semen, sperm concenration, total number sperm,  progressive motility and sperm abnormalities. Bali cattle have a longer semen production period than simmental and limousine cattle. Bali cattle can be used until the age of 9-10 years, while simmental and limousine cattle can only be used until the age of 7-8 years.

Abstract

ABSTRACT Glutamate is one of the amino acids that can act as flavor neurotransmitter. Some lactic acid bacteria (LAB) are known as producers of glutamate. Such LAB could be widely found in many fermentation products. The objectives of this study were to isolate and characterize some glutamate producing LAB isolated from West Sumatera fermented food products (dadih, asam durian, ikan budu and tapai). A total of 1,014 LAB was isolated from the fermented food products. Of these, 40 isolates were considered the best based on their ability to produce inhibition zones >2mm in the presence of 2% CaCO3. Qualitative analysis using thin layer chromatography and quantitative analysis using spectrophotometer revealed that 27 of the 40 LAB isolates produce glutamate. The highest glutamate production was found in LAB of dadih origin (coded as N32). N32 produced a glutamate of 38.25 mg/ml. N32 was found to be gram positive, negative for catalase, oxidase and motility, and can utilize sugars in the form of lactose, glucose and mannitol. The N32 was identified to be Lactobacullus sp. Thus N32 (Lactobacullus sp) from dadih has the potential to produce glutamate acid. Keywords: glutamate, building blocks, lactic acid bacteria, food fermentatio

Abstract

The study aimed to obtain a comprehensive description of the chemical quality decrease of milk adulterated with water from different sources. Experimental research was carried out at the Dairy Production Laboratory, with the main material being milk from the Experimental Farm, Faculty of Animal Science, Unsoed. The study used a completely randomized design (CRD)-factorial. Factor A was three types of milk (no adulterated milk (NA), adulterated by farm water (AFW), and adulterated by house water (AHW)). Factor B was six times of storage (0; 4; 8; 12; 16; 20 hours). There were 18 treatments, each repeated three times. Thus, there were 54 units. Milk quality was observed at controlled room temperature, namely the average temperature of Purwokerto City (300C) in the incubator. Data were analyzed for variance and further tested for linear regression. The analysis of variance showed that the interaction between the type of adulteration and storage time had a very significant effect (P

Abstract

The demand for premium quality meat continues to grow along with changes in the lifestyle of the upper middle class community, the increasing number of tourists and expatriates from abroad. The premium meat must be imported from abroad to meet the needs of special markets such as hotels, restaurants and supermarkets. Some Indonesian cattle cannot produce meat that meets the premium quality criteria, especially tenderness. The hardness of the flesh can be overcome by aging. This study aims to determine the physical and microbiological quality of bali beef with different aging times. This study used bali cattle. The treatments were aging for 1, 21 and 42 days and three different muscle types (Longisimus dorsi, Gluteus medius and Semitendinosus). This study used a completely randomized design (CRD) with a 3 x 3 factorial pattern. If the data obtained were significantly different, it would be continued with the Least Square Means test. The results showed that the combination of aging treatment for 21 days and muscle type (Longisimus dorsi, Semitendinosus) showed the best and most efficient steak tenderness results. Keywords: Bali cattle, aging, physical quality, muscle type

Abstract

ABSTRACTThis research aims to know the impact of repeat breeding on the reproduction efficiency of dairy cattle in Enrekang Regency, South Sulawesi. It was conducted from April to November 2021 in Enrekang regency. This research used 102 dairy cattle of Friesian Holstein (FH). The research design used nonprobability sampling with the purposive sampling method. The samples were grouped based on three parities, namely Nuliparous, Primiparous, and Pluriparous. Prevalence data of repeat breeding was obtained from reproduction efficiency evaluation that was seen from a success of the first AI. If pregnancy does not occur in the first AI, it is repeated in the second AI until the third AI. The result shows that the prevalence of repeat breeding in dairy cattle of FH at the parity of Nuliparous had shown a lower percentage (3,44%) compared to the parity of Primiparous and Primiparous (31,57% and 29,62%). The prevalence of the three parities was tangibly different (significant) with p-value <0,05. Reproduction efficiency of dairy cattle of Nuliparous parity was higher than Primiparous and Pluriparous with value S/C (1,5 vs 2,76 vs 2,52) and CR (65,51% vs 47,36% vs 53,70%). The lower the prevalence value of repeat breeding, the better reproduction efficiency.Keywords: Conception Rate, Reproduction Efficiency, Repeat Breeding, Service Per Conception
