The experiment was carried out to investigate the effect of tryptophan, melatonin and dimethylglycine on the growth performance and meat quality of Japanese quails fed diets contaminated with aflatoxin B1 toxin. In this experiment, 680 Japanese quail from 7 to 35 d of age was allotted to 17 treatments and 4 replicates with 10 Japanese quail in each were performed using a central composite design. The performance of birds was calculated on a weekly basis and at the end of the experiment; the amount of Malondialdehyde in meat was examined. the results showed that tryptophan increase weight gain (P<0.05) and melatonin had an increased effect on feed intake (P<0.05). The effect of tryptophan and as well as the interaction of tryptophan and dimethylglycine reduced the amount of malondialdehyde in meat (P<0.05). The results obtained from this research states that dietary supplementation with Tryptophan and methyl group donors have good antioxidant capacity to reduce aflatoxin B1 poisoning on growth performance and Malondialdehyde content of meat, and the use of these supplements in the diet of Japanese quail seems desirable.

The aim of this study was the comparison of two protocols of estrus synchronization in two natural climates and heat stress condition on reproductive performance and concentration of plasma estrogen and progesterone hormones in Holstein dairy cows. 110 multiparous Holstein dairy cows (28 kg average daily milk yield and parity one to four calved) were randomly assigned to two protocol groups: 1) Double-Ovsynch (DO; n=60), the cows received GnRH-7d-PGF2α-2d-GnRH and Ovsynch (GnRH-7d- PGF2α-56h-GnRH-16h-AI) was initiated 7 d later; 2) Presynch-Ovsynch (PO; n = 50), the cows received PGF2α-14d-PGF2α and Ovsynch was initiated 12 d later. The both of the protocols were done in two seasons of summer and winter. The calving rate in cows that were synchronized at winter season was greater than cows synchronized in summer (36.4 vs 18.2%; P= 0.04). Mean of the number of insemination to conception was lower in cows that synchronized in winter compared to cows synchronized in summer (1.46 vs 1.74; P= 0.02). Mean of measured estrogen and progesterone hormones concentration was higher in cows that synchronized in winter compared to summer (P < 0.05). Overall, mean of reproductive traits and hormones concentration is higher in cows that synchronized in winter than in summer and the protocol of estrus synchronization had no effect on reproductive performance.

This study aims to estimate the response of the number of eggs produced up to 240 days of age (EN240) to the selection of Papua local chickens (PLC) with different genotypes from the 24-bp Indel cPRLp locus. A total of 68 PLCs were taken randomly from several breeders in Manokwari as the basic population for selection (G0). Genotype identification of the 24-bp Indel cPRLp locus was performed G0. Based on the distribution of these genotypes, mating pairs were randomly formed G0-II, G0-DD and G0-ID to produce G1-II, G1-DD, and G1-Control (G0-ID offspring). Heritability of EN240 in G1-II and G1-DD populations were estimated in full-sib (single pairs mating). Individual selection based on breeding value EN240 was carried out on G1-II (♀) and G1-DD (♀) to form the selection generation (GS): GS-II (♀) and GS-DD (♀). Selection was also carried out on G1II (♂) and G1-DD (♂) based on body weight at 240 days (BW240) to become selected GS-II (♀) and GS-DD (♀) mating partners. GS-Control was also formed through 25% random sampling from G1-Control (♂ and ♀). GS mating resulted in the second generation (G2): G2-II, G2-DD, and G2-Control. Age at first laying (AFL), EN240, and mean egg weight (EWA) in hens of G1, GS, and G2 were recorded. Response to selection for EN240 was calculated by two methods predicted selection response (Rp) and actual selection response (Rr). Both methods of calculation yield positive and high values. In actual response (Rr), PLC in II genotypes group are more responsive to the selection treatment than DD genotype group. Selection increase EN240 impact accelerate of AFL and lower the EWA, because of their negative genetic correlation.

The purpose of this research is to determine the effect of avocado seed flour (ASF) supplementation in feed on blood lipids and quail egg yolk cholesterol. The materials were 100 female quails aged 4 weeks old with ration ingredients consist of corn, bran, paddy, soybean meal, fish flour, avocado seed flour, palm oil, CaCO3, premix, lysine, and methionine. The research conducted an experiment with 4 treatments of ASF supplementation levels incorporated into basal feed, namely 0% ASF (R0), 3% ASF (R1), 6% ASF (R2), and 9% ASF (R3). The observed variables included blood cholesterol, High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), triglyceride, and egg yolk cholesterol. The data were subjected to the one-way Analysis of variance (ANOVA) in a completely randomized design, followed by HSD test when differences between treatments were observed. The result showed that ASF supplementation significantly reduced blood cholesterol levels and the egg yolk cholesterol, did not significantly affect LDL and triglyceride levels. The HDL levels and egg yolk cholesterol tend to decrease as the level of ASF increased. It is concluded that avocado seed flour (ASF) supplementation up to 9% is safe for quail feed supplementation.

Protein is one of the nutrient components in milk that is related to product quality. The components of milk protein are divided into casein alpha-s1, beta, alpha-s2, kappa, and whey fractions such as alpha lactalbumin and beta lactoglobulin. There are no existing data of milk protein fraction in dairy cow and goats in Banyumas Regency. This study aimed to determine the profile in form of protein fractions of cow and goat milk in Banyumas. Milk sample from fifty cows and thirty dairy goats was taken by random sampling in some areas. The milk protein profile was identified by the technique of sodium dodecyl sulphate gel electrophoresis (SDSPAGE) and protein quantity prediction by software. The data obtained were analyzed statistically by MannWhitney between cows and goats. The results were significantly different (p<0.05) between cows and goats in molecular weight of protein alpha-S1 casein (29.66 vs 33.37 kDa), alpha-S2 (27.76 vs 29.49 kDa), beta (24 , 48 vs 25.59 kDa) and beta lactoglobulin (15.75 vs 15.97 kDa). The quantity of casein alpha-S1 (7.88 vs 4.16 g/l), alpha-S2 (1.31 vs. 4.02 g/l), beta (8.74 vs 14.24 g/l), kappa (2.41 vs. 4.28 g/l) and alpha lactalbumin (0.91 vs 0.7 g / l) was significantly different (p <0.05) between cow's and goat's milk, respectively. In conclusion, milk protein profile of cows and goats in Banyumas Regency is different.

The objective of the research was to determine the estrous profile of Etawah Crossbred goats after estrous synchronization with different methods. Eighteen does aged 12-24 month old were divided in three groups to receive estrous synchronization treatments (T1 = 14 days intravaginal implant of 60 mg of progesterone (MPA), T2 = two times injection of 5 mg PGF2α (lutalyse) in 11 days interval, and T3 = 10 days of intravaginal implant of 60 mg of progesterone (MPA) + injection of 5 mg PGF2α 48 hours before removal) with six replications. The parameters consisted of estrous behaviour, changes in size and colour of vulva, and duration of estrus when the number of superficial and keratin cells were dominating in the vaginal mucus cell. Data from estrous behaviour and score of vulvar colour was analyzed using Kurkal Wallis test, while onset of estrus, size of vulva slit and estrous duration was analyzed using ANOVA and Duncan test. The result showed that estrous behaviour and changes in color and size of vulva were not significantly different, but estrous duration was significantly different. Estrous duration in T1 (31.30 hour) and T2 (31.10 hour) was significantly longer than that of T3 (11.36 hour). It is concluded that different methods of estrus synchronization affected estrous quality equally but it affected the estrous duration differently based on vaginal mucus cells. Treatment implant vaginal sponge content progesterone for 14 days and double injection of PGF2α with 11-day interval given longest estrous duration.

A crucial trait of a high economic value of goats is calving to more than one kid (prolificacy potency). The high prolificacy potency (> 1 kid) has a higher income compared to single kids. This study described the potential of Indonesian Local Etawah Goat (ILEG) for prolific trait and the morphometric of body and breeding values in various environments as a basis for selection. It involved smallholder farmers who breed ILEG does from 14 villages in East Java. The research was conducted on a field survey to obtain primary data about the phenotypic superior ILEG goats based on the status of the prolific trait. The study used 520 does with 1347 prolific records obtained. The results showed that the prolificacy values ranged from 2.12-1.42 heads/calving (medium to high category). The variation of prolificacy was 0.53, and the breeding values of the prolificacy trait were 1.48-1.74. The average of body morphometrics was varied with the following details. Chest circumference was 81.06 + 4.63 cm, body length was 76.64 + 4.33 cm, shoulder height was 75.34 + 5.83 cm and ear length were 27.44 + 3.02 cm. This study concluded that the prolific rate was medium to high category. The prolific variation was higher than body morphometry variation, and the prolificacy EBVs of breeding villages divided into four unique pattern boxplots. The prolific trait could be the basis for new considerations in the ILEG breeding program, either through selection or mating.

Optimum development of beef cattle is feasible in the potential area with effective strategies. This research was conducted in Banyumas regency. The purpose of this study was to describe the potential of Banyumas Regency in developing beef cattle farming as the basis for its development strategy. A survey method was conducted to obtain the secondary data supported by primary data subjected to simple descriptive statistical analysis consisting of mean values, distribution frequency, cross-tabulation and trend analysis. Ruminant potentials were investigated using LQ analysis, and developmental strategies were formulated using a SWOT analysis. The result showed a fluctuated but positive improvement trend of beef cattle population in Banyumas. Sub-districts potentially developed for beef cattle centres (LQ>1) included Kembaran, Sokaraja, Kalibagor, Kedungbanteng, Karanglewas, Sumbang and Baturraden. A quantitative SWOT matrix analysis showed that the internal factor was 0.0298 (X-axis), and the external factor was – 0.2941 (Y-axis). Conclusively, The key strategy to develop beef cattle in Banyumas was a differential strategy.

The aim of the present study was to evaluate and to compare the physicochemical composition of egg white, and to characterize and estimate the quantitative variations of egg white proteins of different birds’ species (duck, quail, Chicken, partridge and goose). For each bird species, the whole egg temperature, weight, height, density and shape index were evaluated. After breaking the eggs, a visual examination was performed then vitelline (VI) and albumen (AI) indexes and the haugh unit (HU) were measured. The study of the quality and the characterization of egg white proteins were performed by Agarose Gel Electrophoresis. The total egg weight varied within a range of (8.98±0.82 g to 142.91±10.34 g) for quail and goose, respectively. The thickness of the egg yolk was almost three times higher than that of the egg white in all breeds. The egg freshness, measured by HU, was higher in partridge, followed by quail and chicken breeds with values of 88.81±0.09, 87.45±3.33, 81.53±2.16, respectively. The VI shows values of about 0.40. The egg yolk/ white ratio ranged from 47 and the pH varied from 8.37 to 8.95 for all local species studied. The egg white protein content was higher for all species (up to 14.45g/100 g). Three types of proteins are identified by agarose gel electrophoresis (ovalhibitor, ovotransferrin and ovalbumin) with a quantitative difference between bird species. Densitometric analysis shows a qualitative difference due to the presence of type C lysozyme in chicken egg white.
