The objectives of the experiment were to determine the effect of pumpkin flour filler substitution on the nutrition facts of beef sausage. The research material was divided into five substitution treatments of pumpkin flour as a filler in sausage processing, namely: 0, 25, 50, 75, and 100% of the total filler. Each treatment consisted of five replications. The nutrition facts of sausages was calculated based on the nutritional adequacy rate of sausages which refers to the average energy sufficiency for the Indonesian population per person per day, which is 2,150 kcal, total protein 60 g, total fat 67 g, and 30 g food fiber with a 50 g serving size. The data from the calculation of the nutrition facts of sausages were analyzed by analyzing variance and then tested by using Duncan's New Multiple Range Test. The results showed that the sausages substituted filler with pumpkin flour had a highly significant effect (P<0.01) on total protein, fiber, and β-carotene, but did not affect the energy from fat and total fat of beef sausage. Sausages substituted filler with pumpkin flour up to 100% had a higher intake of total protein, fiber, and β-carotene than control sausages.

Beef cattle have a different carcass percentage according to the breed. The percentage of carcass in livestock is an important indicator to determine the potential for meat obtained from cattle. IGF-1 is a gene from the growth gene family which is known to have an influence on the percentage of carcass. A total of 445 samples of Sumba Ongole cattle (156 males and 289 females) were used for genotyping using PCR-RFLP. A total of 237 carcass percentage data were obtained in this study. Data were performed using POPGENE version 1.32 and Microsoft Excel for genetic data and descriptive statistics, respectively. The intensively reared cattle have a higher carcass percentage than the cattle that were reared traditionally. The IGF-1/RsaI in the SO cattle was polymorphic with two alelles (C and T) and three genotype (CC, TT, and CT) but has low values of heterozygosity. The C allele frequency was 0.0034 and T allele frequency was 0.9966. Further studies in larger population are needed to validate the IGF1/RsaI as a candidate genetic marker in the SO cattle.

Quail eggs are a source of animal protein that the public can consume. In addition to the low price, eggs also contain nutrients needed by the body. So it is necessary to pay attention to the quality of the eggs before consuming them. Egg quality that can be assessed is derived from internal and external quality. The quality of the eggs is influenced by various factors, including the content of the ratio given, especially the energy-protein balance of the feed. This study aimed to assess the external and internal quality of quail eggs with different protein and energy levels. The research was carried out for 42 days in the poultry house of the Animal Husbandry Study Program, Faculty of Agriculture, Djuanda University. The feed ingredients formulated in this study as the basic ration were yellow corn, fine bran, soybean meal, fish meal, premix, DCP, CaCO3, CPO, and Cr-O. The design used was a completely randomized design (CRD) with four treatments and four replications with six quails per cage unit. The research data were analyzed by analysis of variance (ANOVA) if the data showed significantly different results (P<0.05), followed by Duncan's test. The variables observed in this study were egg weight, shell weight, percentage of eggshell weight, eggshell thickness, egg index, egg white weight, egg yolk weight, egg white weight percentage, egg yolk weight percentage, Haugh unit (HU). The results showed that the balance of energy and protein differences were not significantly different in all variables. Based on the research results, it can be concluded that the quail ration with the balance of protein 17% and metabolizable energy 2800 kcal/kg has been able to maintain the internal and external quality of eggs in quail and produce standard egg quality.Keywords: protein energi balance; egg white, yolk, haugh unit

The meats physical quality is reflected by meat characteristics and reference for consumers to choose good quality of beef. Several factors that affect the meat quality are interaction genetic and environmental factors during maintenance until post slaughter. The research was conducted to evaluate the meat physical quality with the breeds factor (Red Brahman Crossbred and Droughtmaster), genders (steer and heifer), and ages (PI0, PI2, and PI4). The research materials were 120 samples of Longissimus dorsi ribs 12th from AM FARM abattoir and tested physical quality meat on QC Laboratory of KASA Company. The data were analyzed by ANOVA and Least Significant Difference if there were any significant. The variables observed were pH, meat color, WHC, cooking loss, and tenderness. The results showed that breeds factors have no significant difference on meat physical quality. The factor of genders nested to breeds has very significance (P<0,01) on meat physical quality except for pH and tenderness there wasn’t significant differences. The factor of ages nested to genders nested to breeds has very significant (P<0,01) on meat physical quality except that pH. The conclusion that the evaluation of meat physical quality can be predicted by the relationships of breed, genders, and age factors. Keywords: Meat physical quality, breeds, genders, ages
