Abstract

Milk density and fat content are used as indicators of milk production from dairy farmer by Milk Proccessing Industry (MPI). Some MPI determines the price of milk based on fat and milk lactose content. This research was aimed to study the correlation of fat content, lactose content, and milk density. The material used were 90 of lactation FH cows in the II – III lactation periode and month of lactation are 2 – 3. The analysis method used was simple linear correlation regresion. The results showed that during increased milk fat and lactose contents, will increased milk density. Fat and lactose content are significantly correlated with milk density (P<0.01). The overall calculation shows that there was a relationship between fat content and lactose content to milk density, each 70.8 and 68.7%. Fat content with milk density, and lactose content with milk density showed a strong positive correlations. In conclusion, there was a correlation between fat content and lactose content with milk density. The correlation of fat content and lactose content with milk density were the higher fat and lactose content, higher milk density.

Abstract

This study aimed to determine the quantitative differences of bioactive compounds in jengkol peel with different concentrations of methanol solvents. Maceration method was used for the extraction process, while the content of bioactive compounds was measured using a uv-vis spectrophotometer. This study was designed in a complete randomized design (CRD) with five treatments of solvents (100% aquadest, methanol 24%, methanol 48%, methanol 72%, and methanol 96%) and four replications. The observed variables in this study included the yield of extracts, tannins, saponins, flavonoids, and total phenols. Data was analyzed using Analysis of Variance (ANOVA). The significant different data was further analyzed using DMRT to compare the treatments’ means. The results showed that the use of methanol solvent at different concentrations had no significant effect on the extract yield (4.50-5.50%) and total phenol (0.97-1.52%), whereas it had a significant effect on the content of tannins, saponins, flavonoids. The lowest tannins (2.98%), saponins (7.64%), and flavonoids (0.18%) content were produced by aquadest 100% solvent. The highest tannins (7,83%) content was produced by methanol 72%, while saponin (20.81%) and flavonoid (0.40%) content were produced by methanol 96%. The use of methanol solvent at a concentration of 72% to 96% is able to attract the most effective bioactive compounds in jengkol peel to utilize as a ruminant feed additive.

Abstract

The study aimed to determine feed consumption, body weight gain, and feed conversion of male Magelang ducks with the addition of Azolla microphylla in the ration. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. In each replication, there were 2 male Magelang ducks aged 5 weeks ( weight average is 747,18±103,9 g) and reared for 7 weeks. The treatment consisted of P0 control diet without Azolla microphylla substitution, P1 control diet + Azolla microphylla 10%., P2 control diet + Azolla microphylla 15%., and P3 control diet + Azolla microphylla 20%. Data collected included feed consumption, body weight gain, final body weight, and feed conversion. The data obtained were analyzed by analysis of variance (ANOVA), followed by Duncan's test. The addition of Azolla microphylla up to 20% had no significant effect on feed consumption (average 4706.17 ± 27.89 g), daily body weight gain (average 13.18 ± 1.65 g), and feed conversion (average 7. 38 ± 0.95), but significantly different in final body wight, the addition of Azolla microphylla up to levels of 15% and 20% reduced the final body weight of male Magelang ducks. The conclusions of this study were the addition of Azolla microphylla in the ration up to 20% did not affect feed consumption, daily body weight gain and feed conversion, but the addition of Azolla microphylla above 10% reduced the final body weight of male Magelang ducks. Substitition Azolla microphyla in Magelang duck male could be given up to 10% level.

Abstract

This research aimed to determine the relationship models and phenotypic correlation between the egg weight of Alabio duck (Anas Platyrhynchos Borneo) and the Haugh unit (HU), albumen weight, yolk weight, albumen index, and yolk index. Five hundred eggs weighing 65.7 ± 4.62 g were collected from a flock of 32-week-old commercial laying hens as objects for this experiment. The observed variables were egg weight, albumen weight, yolk weight, albumen index, and yolk index. The data was analyzed using simple linear regression and Pearson's correlation coefficient (r). A significant correlation (P < 0.05) was found between egg weight and HU, albumen weight, yolk weight, and yolk index., with an r of -0.11, 0.83, 0.70, and 0.19, respectively. However, there was no significant correlation between egg weight and albumen index (P > 0.05). These results indicated that egg weight could be used as a variable to appropriately predict albumen weight and yolk weight with the equations y = -0.11 + 0.56x and y = -2.10 + 0.37x for albumen and yolk weight, respectively. However, egg weight as a single variable could not accurately predict the HU and yolk index of the Alabio duck egg.
