Growth Performance and Carcass of Two Different Strain of Broiler Subjected to Different Feed Restriction Methods
Get PDFThe aims of study were to analyze if there is a difference in growth performance of two different strain fed commercial diet with either ad libitum or restricted methods. Two hundred sixteen (216) broiler chicks were allocated to 6 treatments with 6 replicates of 6 chicks/replicate. The experiment used a factorial design 2x3 with 2 strains, and 3 feeding methods, as follows: 1) ad libitum defined in Cobb 500 guidelines as control, 2) quantity restriction (45% of the daily ad libitum consumption), 3) time restriction (standard feed offered for 10h/d). Chicks were exposed to feed restriction from 8-14d. Then, the chickens were fed ad libitum until 35 days of age. The results show that feed restriction significantly (P<0.05) improved feed conversion ratio (FCR) and reduced abdominal fat. Growth performance of broiler fed ad libitum and quantity restriction were significantly (P<0.05) higher than those of time restriction feeding. The growth performance and carcass of strain A were not significantly (P>0.05) different from that of strain B. In conclusion, ad libitum and quantity restriction provide greater growth performance and carcass, but implementing time feed restriction could be a useful for improving FCR and reducing abdominal fat in broiler strain

The research data was processed using Variety Print Analysis and Duncan's Advanced Test. The results showed a significant effect (P<0.05) on lactic acid content, pH, dry matter loss, and Fleigh value. The conclusion of this research shows that the use of P2 treatment (1 kg bran: 100 g molasses: 200 mL LOS) can produce the best fermented bran.
Improvement Performans of Pregnant Cross Awassi Sheep using Silage Total Mixed Ration (Tmr) Feed Technology
Get PDFThe effect of feeding Pakchong and Indigofera-based silage Total Mixed Ration (TMR) on the production performance of pregnant Cross Awassi sheep was evaluated using 6 pregnant sheep, which were randomly divided into two treatment groups. Three sheep were allocated to the control group (P0) which was fed a conventional diet based on fresh forage and standard concentrate, while the other three were placed in the treatment group (P1) which was fed fermented silage TMR for 14 days. Each sheep received feed at 3.5% of body weight per day, with access to drinking water ad libitum. During the 30-day study, feed consumption, daily body weight gain (ADG), feed conversion (FCR), and cempe birth weight were analyzed. The results showed that feed consumption in the treatment group (10.62±1.192 kg/head/day) was higher than the control group (9.84±1.056 kg/head/day). ADG of the treatment group (1.2±0.10 kg) was higher than the control group (0.85±0.12 kg). Birth weight of cempe in the treatment group (4.08±0.769 kg) was higher than the control group (3.72±0.685 kg) with a statistically significant difference (P < 0.05). The FCR value was lower in the treatment group (14.93) than the control group (20.24), indicating better feed efficiency. Therefore, feeding Pakchong and Indigofera-based TMR silage can improve feed efficiency, productivity, and cempe birth weight in pregnant Cross Awassi Sheep
Protein Profile of Limousin Cows and F1 Crossbred with Limousin & Brahman Bulls
Get PDFPlasma protein profiles are important indicators that reflect the health, immunological, and physiological status of cattle in relation to their production and reproductive performance. The objective of this study was to determine the total and fractionated protein levels in the plasma of Indonesian Limousin cows and their F1 offspring. The study sample consisted of 15 animals, including Indonesian Limousin cows and their F1 calves. Blood plasma was analyzed in the laboratory using the biuret method (total protein), bromcresol green (albumin concentration), and globulin (difference between total protein and albumin). Laboratory data were analyzed using SPSS 23 ANOVA and further tested using Duncan's test. Statistical analysis revealed no significant differences (P > 0.05) in protein profiles between F1 LLI and F1 BLI. However, F1 calves from the crossbreeding differed significantly (P < 0.05) from the LI dam in total protein and globulin, except for albumin, which showed no significant difference (P > 0.05). The conclusion of this study is that the protein profiles of F1 LLI and F1 BLI are not significantly different, but F1 LLI shows a tendency toward higher total protein and albumin levels and lower globulin levels. Both F1 crossbreeds have significantly lower total protein and globulin levels compared to the Limousin Indonesia parent, with albumin levels also tending to be lower

The Effect of Adding Cricket Flour (Gryllus bimaculatus) as a Substitute for Soybean Meal in Finisher Feed on Broiler Chicken Welfare
Get PDFThe issue of limited soybean meal availability and dependence on imports in Indonesia necessitates the search for alternative protein sources for animal feed. This study aimed to evaluate the impact of partially replacing soybean meal with cricket flour in the finisher feed of broiler chickens on breast dirtiness, footpad dermatitis (FPD), and hock burn. A total of 100 male Indian River broiler chickens were raised for 5 weeks in a closed-house system, divided into two treatment groups with 5 replications, each consisting of 10 chickens. The birds were housed in pens measuring 1.5 m x 0.75 m. The feeding treatments began during the finisher phase (age 21–35 days), with P0 containing 28.5% soybean meal and P1 containing 18.5% soybean meal + 10% cricket flour. Data on breast dirtiness, FPD, hock burn, and behavior were collected from days 33 to 35 and subsequently scored. The data were analyzed statistically using the Mann-Whitney test with the aid of the Statistical Package for Social Science (SPSS). The results showed that substituting 10% of soybean meal with cricket flour significantly reduced footpad dermatitis (P=0.02), while no significant differences were found in hock burn and breast dirtiness (P>0.05). Based on the findings of this study, it can be inferred that partially substituting soybean meal with cricket meal has the potential as an alternative protein source without causing welfare issues in broiler chickens
National Milk Production Dynamics: Interactions Among Dairy Cattle Population, Milk Imports and Exports in Indonesia 2020–2024
Get PDFThe dairy cattle sub-sector plays a vital role in fulfilling the national demand for animal protein; however, domestic milk production has yet to meet the increasing demand. This study analyzes the impact of dairy cattle population, as well as milk import and export, on milk production in Indonesia from 2020 to 2024. Panel data from various provinces were analyzed using a fixed effects model to identify significant variables. Results indicate that the dairy cattle population has a positive and significant effect on national milk production, with variations across island regions. Conversely, milk import and export showed no significant impact on domestic production. These findings emphasize the importance of region-based development strategies, increasing dairy cattle productivity, and implementing appropriate import protection and substitution policies to enhance national milk production self-sufficiency. This study is expected to provide a basis for policymaking and strategic interventions aimed at sustainable development of the dairy industry
