Abstract

Local sheep are small ruminants that are kept by many farmers. The reproductive success of the animals is influenced by the ration offered. The aim of this study is to evaluate the reproductive performance of multiparous ewes with different flush management. For the study, 16 multiparous ewes were used in a 4 x 4 randomized group design. Treatments consisted of P1 = no flushing, P2 = flushing before and after mating, P3 = flushing before and after mating and at mid-pregnancy, P4 = flushing before and after mating, at mid-pregnancy and at the end of pregnancy. The variables observed were the percentage of pregnancy, number of embryos, embryo diameter, amnion diameter, embryo durability, number of offspring and duration of pregnancy. The results showed that the management of flushing rations influenced the pregnancy rate and amniotic diameter. The number and diameter of embryos, gestation length, number of offspring and embryo lifespan did not differ between treatments (P>0.05). This study concludes that the management of flushing rations affects reproductive performance in terms of pregnancy rate and amniotic diameter.

Abstract

Kambing Marica adalah plasma nutfah endemik di Indonesia yang mempunyai kemampuan daya adaptasi yang cukup baik. Penelitian ini bertujuan untuk mengkaji tingkah laku makan dari kambing Marica yang diberi pakan berbeda serta korelasinya terhadap pertambahan bobot badan harian dan tingkat konsumsi. Penelitian ini menggunakan delapan ekor kambing Marica jantan yang dipelihara pada kandang individu selama delapan minggu. Perlakuan pakan yang diberikan adalah pakan komplit berupa konsentrat dan pakan hijauan (Indigofera sp. dan Pennisetum purpureum). Hasil uji korelasi Pearson menunjukkan bahwa terdapat hubungan signifikan (P<0,05) antara tingkah laku deglutisi terhadap PBBH kambing Marica yang diberi pakan komplit dengan nilai korelasi Pearson yaitu 0,979. Semakin tinggi frekuensi deglutisi yang terjadi maka pertambahan bobot badan harian dari kambing Marica yang diberi pakan komplit akan semakin meningkat. Selain itu, juga terdapat hubungan signifikan (P<0,05) antara tingkah laku deglutisi dan lama ruminasi terhadap konsumsi kambing Marica yang diberi pakan hijauan dengan nilai korelasi Pearson masing-masing yaitu 0,953 dan 0,970, serta periode ruminasi terhadap konsumsi kambing Marica yang diberi pakan komplit dengan nilai korelasi Pearson -0,970. Semakin tinggi frekuensi deglutisi dan waktu yang dibutuhkan kambing Marica dalam proses ruminasi maka tingkat konsumsi pakan akan semakin meningkat.

Abstract

The objective of this study was to evaluate the effect of exercise levels on the hematological and metabolical status, and carcass quality of Garut sheep. In total 24 of Garut sheep used in this study. The levels of exercise contain three treatments namely non exercise, semi exercise and exercise. Blood collection through the jugular vein of sheep samples was carried out at the end of the study, using a 5 mL EDTA tube to measure the haematological condition of the animal sample. Likewise, collecting muscle samples to determine the physical quality of meat.The data was analyzed by analysis of variance and continued by Duncan test for a post hoc test. The results showed that the models of exercise were not significantly (P0.05) affected to hematological level and also carccas quality including juiceness, tenderness, drip loss and water holding capacity. Organoleptic sensory using semiexercise was more favourable meat compare to exercise and non exercise. While for the colour of meat, non exercise treatment was significantly (P0.05) affected to the colour of meat compare to exercise and semi exercise. Furthermore the semi exercise was the best treatment to produce fresh taste meat with good sensory characteristic.

Abstract

The study aimed to identify genetic variation of cDNA sequence from low density lipoprotein receptor (LDLR) gene of hyporesponder cynomolgus macaques. The animal used in this study was one hyporesponder cynomolgus macaque obtained from selection result in Primate Research Center-Bogor Institute of Agriculture (PSSP IPB). Amplification of cDNA from LDLR gene was performed using polymerase chain reaction (PCR) method with 4 pairs of walking primer. Alignment of amplification result sequence from 4 pairs of walking primer generated target sequence of 2353 bp which located on position 188-2540. Analysis of target sequence alignment on reference sequence in GenBank found 8 single nucleotide polymorphism (SNP), namely c408CT; c.1200CT; c.1497CT; c.1644TC; 1791TC; 1804AG; 2088CT; and 2377GA. Of 8 SNPs, c.1804AG and 2377GA. Two SNP (c.1804AG; dan 2377GA) caused changing of amino acids composition namely p.K602E (lysine glutamate) and p.V793I (valine isoleucine). This result proved the potential use of genetic variation of cDNA sequence from LDLR gene as genetic marker for selection of hyporesponder cynomolgus macaques.

Abstract

This study determined the effects of different flushing frequency on performance and blood metabolite profile of ewes and their suckling lambs at pre-weaning period. Twelve multiparous Garut ewes (2 years-old, BW 30.06 ± 6.20 kg) and 18 lambs born to experimental ewes (lambing weight 2.49 ± 0.56 kg) were used in this study. Ewes were randomly assigned into four treatment groups in a complete block design, namely: without flushing (T0: control), flushing at the beginning of mating (T1: 2 weeks before and after mating), two times flushing (T2: T1 + 4 weeks flushing at mid-gestation), and three times flushing (T3: T2 + 2 weeks flushing at before and after parturition). Three times flushing increased ((p<0.05) the crude fat intake, while different flushing frequencies did not affect (p>0.05) dry matter intake and intakes of crude protein, crude fiber, nitrogen-free extract, and total digestible nutrients of ewes at the pre-weaning period. Different flushing frequencies did not change (p>0.05) the productive performances of ewes during the pre-weaning period. Flushing application improved (p<0.05) the average daily gain of pre-weaning lambs at 14 days, but it did not affect the weaning weight of lambs. Two times flushing showed no pre-weaning mortality rate (p<0.05). Flushing application tended to decrease (p=0.08) blood plasma triglyceride of ewes at 21- days, while two times flushing frequency tended to increase blood plasma cholesterol (p=0.05) and triglyceride (p=0.08) of lambs at 21 days. In conclusion, increased flushing frequency supports ewes and their twin lamb growth performance and blood metabolite profile at the pre-weaning period

Abstract

This study aimed to determine the effect of herbal mineral block (HMB) supplementation containing turmeric flour, black soldier fly (BSF), and micro minerals on the performance and blood profile of Dorper crossbred sheep. Ten growing sheep and ten lactating sheep were divided into two treatment groups (P0: complete feed without HMB supplementation and P1: complete feed with HMB supplementation). The research design used was a factorial completely randomized design (2 × 2) with 5 replications. Factor physiological status of growing and lactating sheep and factor supplementation with and without HMB. The data were analyzed using ANOVA and Duncan’s test. The results showed no interaction between physiological status and HMB supplementation on sheep performance (nutrient intake, initial and final body weight, daily body weight gain, and feed efficiency) and blood profile (hematology, metabolites, and minerals). The physiological status had a very significant effect (p<0.01) on nutrient intake, initial and final body weight, daily body weight gain, feed efficiency, and significantly (p<0.05) on serum phosphorus. Supplementation of HMB significantly (p<0.05) increased serum calcium which was crucial for bone an teeth development in growing sheep and milk production in lactating sheep. Serum phosphorus was higher in growing sheep, supporting their bone growth and energy metabolis compared to lactating sheep as it was diverted to the mammary gland.

Abstract

The goal of this study was to evaluate the use of BSF larvae meal and oil as feed components in order to determine their impact on Litopenaeus vannamei shrimp growth performance, nutritional composition, and health response. Three shrimp ponds, each with a diameter of 20 m, were stocked with 72.000 Litopenaeus vannamei post larvae (PL-8), resulting in a stocking density of 229 shrimp per square meter. The trial diets comprised three types: control diet (K), diet containing BSF larvae meal (A), and diet containing BSF larvae meal plus oil (B). The parameters observed in this study included shrimp growth and productivity, feed consumption, feed conversion ratio (FCR), survival rate, nutritional composition (proximate, amino acid profile and fatty acid profile), total bacteria in the shrimp's digestive tract, and total hemocyte count in the shrimp's hemolymph. It was found that subtituting fish meal with 34% BSF larvae meal did not affect the growth performance of shrimp raised in shrimp ponds, compared to the control treatment. The assessment of the amino acid profile has revealed minimal variation between treatment. Nevertheless, both treatments A and B exhibited a decreased concentration of unsaturated fatty acids, specifically omega-3 and omega-6, in comparison to control. Meanwhile, treatment B had the highest levels of saturated fatty acid and omega-9 fatty acid content.

Abstract

Encapsulation technology was developed to address the issues of limited bioavailability and instability associated with black soldier fly oil (BSFO). This research synthesized a nano-emulsion of BSFO utilizing the ultrasonication method, while varying the sources of antioxidants (black seed oil (BSO) and curcumin) and emulsifiers (polyethylene glycol (PEG), whey protein isolate, and Tween 80). The FTIR analysis revealed that the nanoemulsion samples displayed peaks at 3500–3000 cm-1 (O–H stretching), 2900–2700 cm-1 (N–H stretching), and 1700–1500 cm-1 (C=O stretching), suggesting the presence of BSFO, curcumin, BSO, and the characteristics of the emulsifiers. Particle size analysis (PSA) indicated that the emulsion had an average particle size (Z-average) of approximately 229–686 nm. The nan’oemulsion containing PEG showed reduced particle sizes of 218 and 229 nm compared to those with other emulsifiers, attributable to the inherently smaller size of PEG. The HB (BSO with PEG emulsifier) showed a reduced particle size due to the smaller molecular size of the antioxidant BSO compared to curcumin. The polydispersity index (PI) values for HB and CB (curcumin with PEG emulsifier) were 0.3 and 0.2, respectively, indicating relatively homogeneous particles, consistent with the criterion of a PI value below 0.4. Biological assays showed that CB had the highest DPPH inhibition at 83%, while curcumin exhibited 90%, exceeding that of BSO. The inhibition zones of HB are 2.45 cm for Staphylococcus aureus and 2.70 cm for Escherichia coli, representing the highest levels of inhibition. In this study, PEG is the best emulsifier for achieving a smaller nanoemulsion particle size. PEG facilitates the incorporation of BSFO with antioxidants, enhancing stability, efficacy, and bioavailability in various applications, particularly in the medical and food sectors.

Abstract

Objective: This study aimed to investigate effects of Molasses replacement with Vinasse-molasses in ration on the blood metabolite profiles and mRNA expression of Growth Hormone 1 (GH1) of finishing Peranakan Ongole (PO) Cattle.Methods: Ten male PO cattle in averaged 209 ± 21 kg of body weight were equally allocated to receive either molasses or Vinasse-molasses dietary treatments. The concentrate diet was contained of either 15% of molasses (control) or Vinasse-molasses. This study observed the nutrient intake, percentage of weight gain, blood metabolite profiles and GH1 mRNA expression of PO cattle.Results: The result showed that replacing molasses with vinasse-molasses reduced (P<0.05) dry matter intake (DMI) and intakes of crude protein (CP), ether extract (EE), crude fiber (CF), and total digestible nutrient (TDN). Nevertheless, Vinasse-molasses inclusion did not change (P>0.05) percentage of weight gain. Vinasse-molasses increased (P<0.05) the blood urea nitrogen level, while it did not affect (P>0.05) the GH1 mRNA levels.Conclusions: It can be concluded that replacing molasses with vinasse-molasses does not change blood metabolite profile, GH1 mRNA expression and performance of PO cattle.  Vinasse-molasses could be applied as energy sources ingredient to replace molasses in finishing cattle feed.

Abstract

Prediction models for beef meat quality are necessary because production and consumption were significant and increasing yearly. This study aims to create a prediction model for beef freshness quality using the random forest regressor (RFR) algorithm and to improve the accuracy of the predictions using hyperparameter tuning. The use of near-infrared spectroscopy (NIRS) in predicting beef quality is an easy, cheap, and fast technique. This study used six meat quality parameters as prediction target variables for the test. The R² metric was used to evaluate the prediction results and compare the performance of the RFR with default parameters versus the RFR with hyperparameter tuning (RandomSearchCV). Using default parameters, the R-squared (R²) values for color (L*), drip loss (%), pH, storage time (hour), total plate colony (TPC in cfu/g), and water moisture (%) were 0.789, 0.839, 0.734, 0.909, 0.845, and 0.544, respectively. After applying hyperparameter tuning, these R² scores increased to 0.885, 0.931, 0.843, 0.957, 0.903, and 0.739, indicating an overall improvement in the model’s performance. The average performance increase for prediction results for all beef quality parameters is 0.0997 or 14% higher than the default parameters.
