This study aimed to determine the effect of storage time of the second phase of chicken herbal eggs at room temperature on egg weight loss, air cell diameter, and albumen index and also to determine the best storage time for second phase of chicken herbal eggs. This research was conducted on 7 October until 4 November 2020 at the Animal Production Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. This study used a completely randomized design (CRD) with 5 treatments of storage time for herbal eggs for 0, 1, 2, 3, 4 weeks and 4 replications. In each treatment, 12 herbal eggs were used with the total number of herbal egg samples used as many as 60 eggs. The data obtained were tested according to analysis of variance. If there is a significant effect, the Least Significant Difference (LSD) test is carried out at the 5% level. The results of this study indicated that the herbal egg storage treatment had a significant effect (P <0.05) on reducing egg weight, air cell diameter, and albumen index. The storage time of 1 week gave the best effect on the lowest egg weight reduction which was 2,696% ± 0.713, the smallest air cell diameter which was 2.199 ± 0.137 cm and the highest index value albumen which was 0.023 ± 0.004 compared to the storage time of 2, 3 and 4 weeks. Keywords: Air cell diameter, Albumen index, Egg weight loss, Herbal egg, Room temperature

This study aimed to: (1) determine the effect of storage time of herbal eggs of chicken first phase in refrigerator temperature on egg weight loss, air cavity diameter, and albumen index, (2) determine the best storage time for herbal eggs of chicken first phase in refrigerator temperature (7,2oC) on egg weight loss, air cavity diameter, and albumen index. This research was conducted on October 7th – November 4th, 2020, at the Animal Production Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The material used were 60 eggs obtained from Sekuntum Herbal Farm with average weight of 56.67±3.21 g of first phase Lohmann strain chicken (30--40 weeks). The design used was a completely randomized design (CRD) with 5 treatments including storage time for 0, 1, 2, 3, 4 week and 4 replications. The variables observed were egg weight loss, air cavity diameter, and albumen index. The data obtained were analyzed based on Analysis of Variance at 5% significance level. The results that had a significant effect were further tested using the Least Significant Difference (LSD). The results showed that the storage time gave a significant effect (P<0.05) on egg weight loss, air cavity diameter, and albumen index of first phase chicken eggs. The storage time of herbal eggs for 1 week at refrigerator temperature showed better quality based on egg weight loss which was still low (1.14%), air cavity diameter (1.983cm), and albumen index (0.073). Key words: Herbal eggs, egg weight loss, air cavity, albumen index, refrigerator

This study aimed to determine the dry matter digestibility (DMD) and organic matter digestibility (OMD) in forage corn silage with two varieties (BISI-18 and NK-212) given two types of starter (molasses and bran). This research was conducted in May—August 2019 at the Laboratory of Animal Nutrition and Feed, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. In vitro analysis of dry matter digestibility and organic matter digestibility by Tilley and Terry (1963). The experimental design used was factorial 2x2 in a Completely Randomized Design (CRD), with 3 replications. The factors studied were (1) corn stover varieties which consisted of two varieties (BISI-18 and NK-212) and (2) starter which consisted of two types of starter (molasses and bran). The results of this study indicate that there was no interaction (P>0,05) between the use of varieties of corn forage and starter sugar cane the dry matter digestibility, and organic matter digestibility. Duncan furher test, the use of different corn forage varieties has a significant effect (P<0,05) on silage the the dry matter digestibility, and organic matter digestibility. The best DMD value is found in the BISI-18 variety (59.07%) and The best OMD value is found in the BISI-18 variety (58.20%). The use of different types of starter has no significant effect (P>0.05) on the determine the dry matter digestibility, and organic matter digestibility of silage.

This study aimed to determine the effect of various mixture of cassava leaves and cassava waste fermented by Aspergillus niger on dry matter, crude fiber, and crude protein. This research was carried out in August 2021--September 2021 at the Animal Nutrition and Feeding Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The experimental design used was a completely randomized design (CRD) with 5 treatments and 3 replications. The treatments were cassava waste without mixture + Aspergillus niger 1% BK (P0), cassava leaves without mixture + Aspergillus niger 1% BK (P1), cassava waste 20% + cassava leaves 80% + Aspergillus niger 1% BK (P2), cassava waste 40% + cassava leaves 60% + Aspergillus niger 1% BK (P3), and cassava waste 60% + 40% cassava leaves + Aspergillus niger 1% BK (P4). The variables observed in this study included dry matter, crude fiber, and crude protein of product of fermentation. The data obtained were analyzed using analysis of variance with a significance level of 1% or 5% and continued with Duncan's Multiple Range Test. The results showed that fermentation with Aspergillus niger 1% BK could reduce the crude fiber content in a mixture of cassava waste and cassava leaves from 18.24% to 12.45% after fermentation, and could increase the crude protein content of fermented products. While the best response of fermentation of mixture of cassava waste and cassava leaves on the chemical quality of dry matter, crude fiber, and crude protein was obtained in a mixture of 40% cassava waste + 60% cassava leaves + Aspergillus niger 1% BK which produced 20.48% crude protein with low crude fiber of 10.81%. Keywords: Aspergillus niger, crude fiber, crude protein, Dry matter, fermentation

Demand for crossbred chicken (Indonesian native chicken x laying hens) continues to increase. This study aimed to find the best-crossbred chicken resulting from crossing between local/native roosters and laying hens which produce the highest body weight up to eight weeks of age, and its growth prediction using the Gompertz function. Eighteen (18) native roosters (9 Bangkok roosters, 9 Pelung roosters) and 36 laying hens of strains Isa brown, Lohman brown, and Hyline brown (12 each) were used in this study to produce 360 crossbred chickens. Factorial 2x3 (two male local roosters versus three strains of laying hens) using a completely randomized design with 3 replications was applied in this study. The results showed an interaction between native roosters and layer hens on the body weight of crossbred chickens at eight weeks of age. Crossbred chicken from crossing between Pelung rooster and Isa brown layer hen was the best in body weight at eight weeks of age. This crossbred chicken would reach a mature weight of 3026.89 g with an inflection weight of 1113.53 g and an inflection age of 7.40 weeks. In conclusion, crossbred chicken from crossing between Pelung roosters and layer hens of Isa brown strain was the best crossbred with the highest body weight at eight weeks of age. This crossbred chicken could be an alternative for fulfilling the demand for local chicken in Indonesia because the slaughter age could be shortened from 8 months to 8 weeks.
