Abstract

An experiment in a completely randomize design was undertaken to study the use of fresh-watergreen algae as a yolk coloring agent in Mojosari ducks during a laying period on productiveperformance and egg quality from 36 to 44 wk of age. A total of 80 thirty-six wk–old laying ducks weredivided into four dietary treatments and each of four replicates with 5 birds. Diets were formulated witha commercial concentrate, rice bran and yellow corn (2:4:4) according to a commercial standard diet asa control, and three other dietary treatments with 2, 4 or 8% of green algae were included. Fresh watergreen algae had a significant effect on the feed uptake, egg production, and feed conversion ratio (FCR)(p<0.05). Egg production and FCR improved at added 2 and 4% green algae. No differences wereobserved in egg yolk index, albumen index, Haugh Unit, and egg shell thickness (P>0.05) except eggyolk color. The yolk color increased within 7 days after feeding with the test diets. The present studyindicated that fresh-water green algae could be used as a natural coloring agent in laying ducks and at8% of green algae showed the highest score of (Roche Yellow Color-15).

Abstract

The aims of study was to compare the glycerol concentration in Tris glucose egg yolk (TGEY)diluents on the quality of deer frozen semen. Semen was collected from 5 Timor deer usingelectroejaculator. Immediately after collection the semen was evaluated macroscopic andmicroscopically. After initial evaluation, the semen was divided into three tubes and extended with Trisegg yolk with three different glycerol concentrations, which were 10% (TGEY10); 12% (TGEY12) and14% (TGEY14). The sperm motility, viability, acrosome intact and membrane intact were evaluated inraw semen, after equilibration and after thawing. The results showed that there were no differences(p>0.05) on the sperm motility, viability as well as sperm acrosome intact. Sperm membrane intact inTGEY10 (52.50±5.89%) and TGEY14 (51.50±4.12 %) were higher (p<0.05) than in TGEY12(49.00±6.58). It was concluded that 10, 12 or 14% glycerol concentration can be used for Timor deersemen cryopreservation.

Abstract

The aims of the research were to confirm the short estrous cycles and determine the blood level ofestradiol 17-β and ovarian follicukar dynamics in these cases. The research was conducted using sevenBali cattle, approximately 2 years of age, kept in healthy condition with normal estrous cycles.Observation of estrus symptoms was performed daily. Ovarian follicles was examined and measuredusing ultrasonography started at the estrus day. Blood samples were collected from jugular vein, bloodsample collection and ultrasonographical examination of the ovaries were performed daily in the sametime. Serum level of estradiol 17-β was performed using EIA. The short cycle estrus were observed in 4Bali cattle (n=7) among natural estrous cycle. They have only one wave ovarian follicular developmentwhereas the maximal size of ovarian follicles ovulation likes the normal cycle The duration of shortestrous cycle was 7-10 days with normal usual estrus behavior. The peak of blood serum level was107.77 ± 55.94 pg/ml when the diameter dominant follicle of short estrous cycle was reached 10.5 ±0.38 mm. It can be concluded that the short estrous cycles may occur in Bali cattle after puberty amongnormal cycles.

Abstract

Research was aimed to determine nitrogen balance, microbial protein synthesis, and blood metabolites of male Bali cattle fattening fed ration with different protein level in smallholder farms North Central Timor, Province of East Timor Tenggara, Indonesia. The cattle used were 18 heads aged 2 to 2.5 years with initial body weight of 229.86±12.46 kg. The cattle were randomly divided into three treatment groups. The T0 group was given feed the same as traditional fattening cattle practices by farmers,T1 group fed ration containing 12% crude protein (CP) and 72% total digestible nutrients (TDN), andT2 group fedration containing 15% CP and 72%TDN. Cattle were fed individually for 90 days and drinkingwater ad libitum. The data were analyzedby analysis of variance.Results of research indicated the nitrogen balance, and blood urea nitrogen between T1 and T2 were relatively similar, but those were higher (P<0.05) than T0 . In contrast, microbial proteins synthesis, and blood glucose at 0, 4, and 6 hours before and after feeding were relatively similar between the groups. Blood glucose of T2 at 2 hours after intake were higher (P <0.05) than T0, but was not different with T1 . It can be concluded, that the fattening maleBali cattle fed ration containing 12% CP and 72% TDNimprovedthe nitrogen balance and blood metabolites, butit was no positive effect on the microbial proteins and N synthesis.

Abstract

The purpose of this study was to clarify effect of the combination of waru leaf (Hibiscus tiliaceus) sapponin with soybean meal protein in the goat diet on some parameters of carbohydrate metabolism. The study used 16 Ettawah cross bred male goats with body weight average of 16 kg and aged at 7 months. The dietary treatments were: T0 = total mixed ration (0.09% of Hibiscus tiliaceus leaf sapponin, 8.69 % of CP, 62.11% of TDN), T1 = T0 + 3% soybean meal protein, T2 = T0 + 6% soybean meal protein, and T3 = T0 + 9% soybean meal protein. The treatments were allotted in a completely randomized design, with 4 treatments and 4 replicates of each. The results showed that dietary treatments did not effect significantly (P>0.05) on intakes of dry matter, carbohydrate, energy, ruminal butirat and valerat concentrations. Crude protein intake, feed digestibility, ruminal acetate and propionate concentrations, ratio of non-glucogenic to glucogenic VFAs, and estimated methane production were increased (P<0.05) by dietary experiments. The protein supplementation in a Hibiscus tiliaceus leaf contained diet should be balanced with the energy level.

Abstract

An experiment was conducted to observe the effect of dietary fiber given in mash form onperformance and cannibalism mortality in laying hens. Three different diets: a wheat-based diet, a guargum diet (a wheat-based diet + 20 g/kg guar gum) and a lucerne meal diet (a wheat-based diet + 40 g/kglucerne meal) in mash form were offered for 12 weeks. The results showed that birds fed guar gum diethad the lowest intake (p<0.01), egg weight (p<0.05), body weight (p<0.05) and the lowest eggproduction (p<0.01) compared to those fed other diets. Diets did not have a significant effect (p>0.05)on feed to egg ratio and cannibalism mortality, but numerically the birds fed the guar gum diet had thehighest mortality (11.3%) and the lucerne diet had the lowest (6.9%). The lack of profound differenceswas probably due to the diets were given in mash form. In conclusion, diets containing high soluble NSPreduced the performance and increased the mortality due to cannibalism in laying hens. The use of mashform may have a potential in reducing the negative effect of soluble NSP on cannibalism.

Abstract

The objective of the current study was to investigate the effect of addition an amino acid or its combination with EDTA on DNA integrity and morphometry sperm heads of freeze-dried bovine spermatozoa. Spermatozoa were freeze-dried in medium with the addition of an amino acid glycine, cysteine, glutamine, or its combination with EDTA. Sperm head morphometry was identified at 400X magnification using Axio Vision(Zeiss Company, Germany), while for membrane plasma integrity (MPI) determined by calculation of the percentage of spermatozoa having intact plasma membrane by osmotic resistance test method and DNA integrity analysis using acridine orange staining. Sperm head had declined in size after the freeze-drying process, MPI of FD spermatozoa gradually increased significantly when FD solution was added with an amino acid solution (glycine, cysteine) and its combination with EDTA. DNA integrity of all freeze-dried spermatozoa treatments was remaining intact, no significantly different (P>0.01) among treatments. The present study concluded that the addition of an amino acid (glycine, cysteine) or its combination with EDTA could be reduced morphometric sperm heads and plasma membrane damage of freeze-dried bovine spermatozoa, however, DNA integrity of bovine sperm nucleus remaining intact after the freeze-drying process without addition both amino acids and EDTA.

Abstract

The KLF3 gene was a potential genetic marker candidate due to its involvement in many biological processes such as cell proliferation, cell differentiation, and apoptosis. This study was conducted to identify the KLF3 gene polymorphism in the Indonesian FH cattle. A total of 302 individual cattle blood samples from West Java (n=138), Central Java (n=34), and East Java (n=130) provincies were used to obtainDNA samples. The DNA sequencing was performed using 9 samples (each location of sampling represented by 3 samples) for initial identification of the KLF3 gene polymorphismand followed by PCR-RFLP analysis using all DNA samples. There were two SNPs identified in the intron region of the KLF3 gene i.e. SNP g.59607486delC and SNP g.59607554A>G. The SNP g.59607554A>G could be detected using PCR-RFLP method with HpyCH4IV restriction enzyme and resulted three genotypes of the KLF3 gene (AA, AG, and GG) but its heterozygosity value was low in the Indonesian FH cattle. The AA genotype has the highest frequency (0.73), while the AGand GG genotypes frequency were 0.24 and 0.03, respectively. Information about the KLF3 gene polymorphism in this study can be considered for further study to analyse its association with milk and protein yield traits.
