Abstract

The objective of this research was to improve beneficial value of cacao pod as sheep feedingredients comprising up to 50% total feed. This research was conducted in two stages. Stage 1 wascacao pod fermentation. Completely randomized design with 3x3 factorial patterns was used in thisstage, in which factor I was microbial inoculum dosage of 0%, 0.05% and 0.1% and factor II wasincubation period of 0, 3 and 6 days. Result demonstrated that six-day fermentation with 0.05%microbial inoculum could lower cacao NDF, ADF and theobromine. The optimum inoculum dosage andfermentation time from stage 1 was applied to stage 2. Stage 2 was rumen microbial fermentation test.This research administrated 3x3 of latin square design. In period I sheep were fed with CF0 (nonfermentedcomplete feed), in period II sheep were given CF 1 (complete feed containing fermentedcacao pod) and in period III sheep were given CF2 (fermented complete feed based cacao pod). Resultdemonstrated that pH value of sheep microbial liquid in treatment of CF0, CF1 and CF2 was in normalpH range and did not affect volatile fatty acids (VFA) and ammonia. In conclusion, supplementing up to 50% of feed with complete feed containing fermented or non-fermented cacao pod did not affect theprocess of rumen microbial fermentation.

Abstract

High occurrence of aflatoxin contamination in feed stuffs implicates for a long time experience ofaflatoxin B1 (AFB1) exposure to dairy cattle in Indonesia. A latin square 4X4 research design wasadopted to study the characteristic of AFB1 carry-over rate (COR) of Indonesian crossbred FriesianHolstein (PFH) as effects of inclusions of AFB1-naturally contaminated feed and bentonite in the diet.Results showed a rapid aflatoxin M1 (AFM1) excretion in the milk, detected in the first milking sampleor 10 hours after AFB1 ingestion. The steady state of AFM1 concentration observed since the first dayof treatment period and AFM1 contamination was still detected until 5 days after AFB1 removed fromthe diet. The COR in this study was observed 0.1%. AFM1 concentration was highly significantly(P<0.01) affected by treatments. However, there were no significant effects (P>0.05) of levels of AFB1and bentonite inclusions on the COR, nutrients intake, milk production, and milk composition. IIt isconcluded that AFM1 concentration was influenced by AFB1 intake and that transfer of AFB1-feed intoAFM1-milk (COR) in PFH cow was lower compare to reported COR value for dairy cow in sub tropicalregion.

Abstract

This research was aimed to examine the effect of undegraded protein supplementation on nutrientsintake, production and milk composition in dairy cows. The purpose of this research was to provideinformation on the undegraded protein supplementation to increase milk production and composition indairy cows. The research was conducted for 3 months in Boyolali-Central Java. The study used 20lactation cows (<3 months of lactation), aged 3 to 3.5 years with body weight from 350 to 400 kg. Thecows were then randomly divided into 2 groups of ten based on their body weight, milk production,lactation period and age. The first group (control) and the second group (treated), both were fed dietbased on NRC (1987). The second group was added undegraded protein (UDP) of 30 g/l milk that mixedby concentrate. The observed variables were dry matter intake (DM), organic matter (OM), crudeprotein (CP), neutral detergent fiber (NDF), milk production and milk composition including fat, proteinand solid non fat (SNF). Data obtained were examined by t-test.The results showed that intake of DM, OM, and the NDF of treated and control groups were notdifferent (9.57; 8.49; 4.98 vs 9.44; 8.38; 5.40 kg/cow/d, respectively); however, protein intake of treatedgroup was higher (P<0.01) than that of the control group (1097 vs. 1210g/cow/d). Milk production ofcows receiving UDP supplementation tended to be higher than that in the control group (+ 1:45kg/cow/d). Although they tended to be lower in fat (4.13 vs. 3.88%), protein (2.45 vs. 2.27%) and SNF(7.26 vs. 6.94%), but protein and fat production were higher for cows receiving UDP supplementation(366 each; 214 vs. 330; 196g/cow/d). It can be concluded that UDP supplementation increased milk, fatproduction and milk protein but it tended to reduce the level of fat, protein and SNF milk.

Abstract

Crossing between cattle breeds is the one way to improve the genetic quality of cattle. Controlling crosses using genetic markers will speed up the process. The IGFBP-3 gene is a potential marker of selection due to its role in regulating growth and metabolism in cattle. The aim of this study was to determine the effect of genotype on birth size and birth weight using IBFBP-3 gene marker. A total of 32 cattle consisted of 10 Brahman Cross cattle, 14 cattle results of Brahman Cross cow crosses with Belgian Blue bull, and 8 cattle results of Brahman Cross cow crosses with Wagyu bull. Sequences of 563 bp, including the part intron 2, exon 3, and the part intron 3. Genotyping was done by sequencing method and PCR-RFLP method with the restriction enzyme PvuII. An SNP was identified at location g 3,930 (G>A). Two genotypes were observed, namely GA and GG. The genotype did not affect the performance of birth (body weight, body length, height at withers, heart girth) of the research sample. Birth traits are influenced by the cattle breed, it can be seen that Brahman Cross cattle have a body length that is bigger than the other crossbred.

Abstract

This study aims to analyze the consumer preferences about choosing a place to buy beef and beef attribute product influence in buying decision of consumers in Yogyakarta. There were 300 beef consumers selected near traditional markets, butcher or meat shops, supermarkets, restaurants and food stalls for the survey using the questionnaire. The data were analyzed descriptively and used the chi-square test to evaluate the relationship between demographic characteristics and the consumers' choice of place when buying beef in Yogyakarta. The study reveals that most respondents buy beef at butcher or meat shops, followed by traditional markets and supermarkets. Consumers consider price, top quality of beef, the freshness of the product, shopping convenience and friends with sellers as the top five reasons when they choose a place to buy beef. Further, there is no correlation between demographic aspects with consumer preferences in choosing a place to buy beef. Finally, the beef attributes consumers consider when buying beef are the halal slaughtering method, bright red colour, quality assured and beef cuts.
