The study was conducted to evaluate the effect, consistency, and economic viability of using different brands and dilution levels of liquid anionic surfactants to detect Mastitis in dairy cattle. Fifty-five milk samples were collected and subjected to macroscopic evaluation at a cattle farm located in Sta. Maria, Bulacan, Philippines. Milk samples were brought to the Philippine Carabao Center National Headquarters and Genepool Science City of Muñoz, Nueva Ecija for Somatic Cell Count. The experiment used 10 treatments with 3 replications arranged in a Completely Randomized Design. The macroscopic evaluation results showed that liquid anionic surfactants at 30%-50% dilution levels could detect Mastitis in dairy cattle. This was validated by the somatic cell count results from PCC Dairy Laboratory. On the other hand, statistical analysis results revealed that the treatments and the control (commercial mastitis test) were comparable except for brand Z at a 40% dilution rate. Brand Z at 30% and 50% dilution rate were found to be consistent among other treatments in detecting Mastitis in dairy cattle. In terms of economic viability, brand X and brand Y at 30% were the cheapest and had the lowest production cost and highest percentage savings.

The present study was carried out to investigate the effect of fresh and dry eucalyptus leaves on feed intake, digestibility, rumen fermentation activity, blood serum biochemical, milk yield and composition, feed conversion and economic efficiency of lactating buffaloes. Twenty lactating multiparous Egyptian buffaloes in 3rd and 5th lactation seasons and weighed 550 kg on average were used in complete randomized design after 8 weeks of calving (peak period) and assigned into five similar groups of four buffaloes each according to milk yield and live body weight. Animals were individually fed on a basal ration (BR) consisted of 40% concentrate feed mixture (CFM), 30% fresh berseem (FB) and 30% rice straw (RS). The first group was un supplemented and served as a control group (G1). Those in the second and third groups were supplemented with 50 and 100 g of fresh eucalyptus leaves per head per day for low level (G2) and high level (G3). Animals in the fourth and fifth groups were supplemented with 15 and 30 g of dry eucalyptus leaves per head per day for low level (G4) and high level (G5). G3 recorded significantly the highest digestibility coefficients of all nutrients and feeding values followed by G2, G5 and G4, whereas control one (G1) had the lowest values. Ruminal pH value tended to decreased with Eucalyptus leaves additive. Group 3 showed significantly the highest TVFA’s and the lowest NH3-N concentration followed by G2, G5 and G4, while G1 had the opposite trend. Moreover, G3 revealed significantly the highest concentrations of total protein and globulin and the lowest urea, urea-N and creatinine and activity of SGOT and SGPT enzymes in blood serum followed by G2, G5 and G4, while G1 had reverse values. However, serum albumin concentration was nearly similar for the different groups. Group 3 recorded significantly the highest feed intake (DM, TDN and DCP), yield of actual milk and 7% FCM, milk composition (fat, protein, lactose, SNF, TS and ash) and milk constituents yield followed by G2, G5 and G4, while G1 had the lowest values. Also, G3 recorded significantly the lowest amounts of DM, TDN and DCP per 1 kg 7% FCM followed by G2, G5 and G4, while G1 had the highest amounts. At the same time, G3 recorded significantly the highest values of feed cost, output of 7% FCM yield, net revenue and economic efficiency and the lowest feed cost per kg 7% FCM followed by G2, G5 and G4, while G1 had the opposite values. In conclusion, addition of fresh eucalyptus leaves at the level of 100 g/head/day recorded the best improvements in feed intake, digestibility, rumen fermentation activity, some blood serum biochemical, milk yield and composition, feed conversion and economic efficiency of lactating buffaloes.

This study aimed primarily to investigate the effect of Zn-Proteinate (Zn-Prot) supplementation on in vitro rumen digestibility and rumen fermentation. This research used a completely randomized design with four treatments and four replicates. The experimental treatment was the supplementation of various levels of Zn-Prot (0; 12.5 ppm; 25 ppm, and 37.5 ppm) on a dry matter basis. Parameters determined were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), partial volatile fatty acid (VFA) (acetate, propionate, and butyrate), A/P ratio, CH4, and the efficiency of the conversion hexose to VFA. Data were analyzed using ANOVA. The results showed that goats fed with a diet supplemented with 25 ppm Zn-Prot had the highest IVDMD and IVOMD values. There was no significant effect on the VFA and CH4 concentrations, A/P ratio, and the efficiency of the hexose-VFA conversion within treatment groups. In conclusion, supplementing 25 ppm of Zn-Prot into the diet of dairy goat increase the dry matter and organic matter digestibility.

In general, the determination of the price of cattle is based on the condition of the cattle's body. This will result in an unsatisfactory transfer of revenue value for farmers, because the bargaining position is still weak. In addition, transactions in the marketing chain of beef products and their by-products have not yet been solidly established, so the obligations and rights of some parties are not guaranteed. The objective was to analyze the role of stakeholders in each supply chain and distribution of value chains as revenue in the marketing transactions of cattle, beef, and derivative products. The study was conducted in West Timor, which has 85.0% of the cattle population in NTT. Four sample districts (Kupang, TTS, TTU and Belu) in 8 sample sub- districts or 16 sample villages were included in the study. Respondents in marketing activities consisted of farmers, village traders, sub-district/district traders, slaughter traders, inter-island traders, by-product/waste traders, as well as beef, cowhide, bone, and fat/blood processing industries. Data collection were conducted by a questionnaire-based interview. The data were analyzed descriptively-quantitatively with a supply chain analysis model. It canbe concluded that (1) Market supply chains include cattle traders (farmers, village traders, sub-district traders, inter-island traders and slaughtering traders), as well as beef traders (fresh beef retailers, frozen beef exporting traders, and processed beef products traders); (2) The ideal model of the value chain in the form of revenue share from marketing of cattle, beef, processed beef products, by-products, and cattle waste has not been fully established in NTT; (3) The ideal model includes five marketing blocks (cattle block, beef block, processed beef block, by-product block, and waste block).

The present study examined the quantitative and qualitative physical parameters of prolific local ewes in Bawen and Jambu districts, Central Java. We used purposive sampling to select and categorized 132 local, three-lambing ewes into three groups based on their prolific capacity: 66 single, 49 twins and 17 triplets. The data were subjected to analysis of variance using Chi-Square. The result showed that many quantitative properties of prolific ewes resembled those of fat-tailed sheep: thin tail, highly significant (P<0.01) compared to fat tails; straight face, highly significant (P<0.01); and fewer convex face and short body, significant (P<0.05) with a tall body in the non-prolific ewes. Few prolific ewes had big ears and black-white wool and significantly different (P<0.05) from the non-prolific ewes. Conclusively, local prolific ewes had a qualitative appearance more closely related to that of thin-tailed ewes, but greater quantitative performances than the non-prolific ewes.

The aim of this research was to study the effects of curcumin administration, injection of PMSG hormone, and the combination of curcumin supplementation and PMSG injection on the physiological parameters and performance of female Muscovy ducks. The objects of this research were 40 young female Muscovy ducks, aged 24 weeks, subjected to treatments: control (P1), curcumin supplementation at a dose of 24 mg/100 g feed (P2), intramuscular injection of PMSG hormone at a dose of 0.015 mL/hen (P3), and the combination of curcumin and PMSG (P4). The results showed that the treatment gave nonsignificant improvements in Muscovy duck performances, including feed consumption, egg production, and the day of laying period and molting period. Treatment gave a significant increase in serum estradiol concentration at molting period after treatment. This study concluded that the treatment provides no significant improvement in the performance of female Muscovy ducks because the genetic diversity of Indonesian ducks remains high.

The study investigated the productivity of smallholder broiler farming with and without AGP to identify the difference between the utilization and absence of antibiotic growth promoter (AGP) incorporated into the broiler feed based on production (feed efficiency and cumulative performance index), economy (farming capacity and income), and socio-demography (farmers’ education background, age, farming experience, and farming motivation) in Central Java Province. The study was conducted through a survey of broiler farmers in one partnership company. The data analysis included analysis of variance based on a stratified GLM (general linear model) and correlation analysis. The result did not identify significant differences in the production aspects in either AGP or non-AGP farming, among different regencies, and farm size. In 2018, when farms stop using the AGP, the farm production is better than in 2017 when the AGP was used. Based on the economic aspect, the AGP and non-AGP administration did not affect farming capacity and income. The socio-demographic aspect showed that education significantly affected the success of broiler farming, while farmers’ age, farming experience, and farming motivation did not affect the production of broiler farming. The result of correlation analysis showed that education background contributed to feeding efficiency and cumulative performance index. The conclusions are (1) broilers fed with either AGP or non-AGP containing feed showed relatively similar performance, (2) the government policy on the prohibition of AGP does not contribute to the decrease of farmers’ income and (3) the demographic aspect affecting the success of the broiler farming business is the farmers’ education level.

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 (SDS- PAGE) and protein quantity prediction by software. The data obtained were analyzed statistically by Mann- Whitney 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.

HSD17β13 (17beta 13-Hydroxysteroid dehydrogenases) are important enzymes in steroid metabolism. This study investigated the polymorphisms and expression of the HSD17β13 gene in lamb quality traits in Indonesian sheep. A total of 200 of rams of seven breeds administered in the study were Javanese fat- tailed (JFT), Javanese thin-tailed (JTT), Garut sheep (GS), Jonggol sheep (JS), Garut composite sheep (GCS), Compass agrinac sheep (CAS), Barbados cross sheep (BCS) aged 10-12 months and weighed 20-30 kg. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) and MspI enzyme restriction were performed to identify the polymorphism of the HSD17β13 gene. The lamb quality traits were measured for physical quality, flavor, odor, and fatty acid composition. The results showed that the HSD17β13 gene was polymorphic and had three genotypes i.e., CC, CT, and TT. The highest genotype frequency was the CC when compared to the other genotypes. The allele frequency of HSD17β13 gene was not in Hardy Weinberg Equilibrium. The polymorphism of HSD17β13 gene was significantly (P<0.05) associated with the fatty acid composition and Saturated Fatty Acid (SFA), i.e., tridecanoic acid (C13:0), arachidic acid (C20:0), henecosanoic acid (C21:0), and tricosanoic acid (C23:0). The polymorphism was also significantly associated with the Monounsaturated Fatty Acid (MUFA) i.e. ginkgoleic acid (C17:1) and nervonoic acid (C24:1), and Polyunsaturated Fatty Acid (PUFA) i.e. eicosedienoic acid (C20:2). The level of expression of the HSD17β13 gene based on quantitative real time-PCR analysis results was not significantly different (P>0.05) among genotypes for lamb quality traits. It can be concluded that the polymorphism of HSD17β13 gene was associated with the fatty acid composition of lamb in Indonesian sheep.
