Abstract

Sumba Ongole (Bos indicus) is a native beef cattle that adapts well in Sumba Island of Indonesia. This study was carried out to perform a genome-wide association study for body weight (BW) and carcass weight (CW) in Sumba Ongole (SO) bulls. A total of forty-eight (n=48) SO bulls were used in this study. The data were collected from the slaughterhouse at Bogor City, West Java, Indonesia, and were analyzed using a genomic software of TASSEL 5.0 to obtain the best genetic marker. The result showed that the threshold Manhattan plot (-Log10P3) was used to select SNP markers for BW and CW in SO bulls. The two (2) SNP markers at BTA1, i.e., ARS-BFGL-NGS-3162 (CEP63 gene) and ARS-BFGL-NGS-78232 were significantly associated with BW and CW, respectively. Nonetheless, the genetic diversity in both SNP markers was low, with a PIC value of less than 0.30. In conclusion, the heterozygous TG bulls in CEP63 gene have higher CW than homozygous TT bulls.

Abstract

Green Tea Extract, or GTE, is a powerful antioxidant that can be added to the extender to maintain the quality of Bali bull semen before and after freezing. This study aimed to evaluate the impact of the GTE addition in the extender on the sperm kinematic and sperm morphology from frozen semen of Bali bull. Five Bali bulls from the NAIC, were used as semen sources. In this study, there were four different treatments: a control (Tris-egg yolk without GTE), a GTE0.05 (100 mL tris egg yolk with 0.05 mg of GTE), a GTE0.10 (100 mL tris egg yolk with 0.10 mg of GTE), and a GTE0.15 (100 mL tris egg yolk with 0.15 mg of GTE). A sperm analyzer (CASA) was used to observe the sperm kinematics and morphology. Compared to the control group, adding different concentrations of GTE to the semen extender did not affect the sperm’s morphology. Before freezing, adding GTE0.05 increases total and progressive motility as well as VAP, VCL, and VSL after thawing. GTE0.15 increases STR and ALH. The conclusion is that GTE additions at doses of 0.05 mg/100 mL and 0.15 mg/100 mL can increase sperm kinematics parameters, but sperm morphology is not affected by the GTE.

Abstract

Yogurt, with the addition of herbal ingredients can add efficacy and value of its benefits. Several studies have proven that cinnamon, aloe vera, and fenugreek seeds have properties as antidiabetic and hypolipidemic. The purpose of this study was to evaluate the antidiabetic and hypolipidemic potential of yogurt with the addition of a combination of two or three types of herbal extracts, such as cinnamon, fenugreek seeds, and aloe vera, in diabetic rats. Diabetic rats were divided into six groups and given treatment for 21 days. Rats’ blood was taken to test blood glucose levels using glucometers, insulin with the ELISA method, blood lipid profiles, and kidney and liver functions using a chemistry analyzer. The data were statistically analyzed using one-way ANOVA followed by the Duncan test. The results showed that yogurt added with several combinations of herbal extracts such as cinnamon, aloe vera, and fenugreek seeds (III, IV, V, and VI) could significantly reduce blood glucose levels, increase insulin levels, improve lipid profiles, and improve kidney and liver functions in diabetic rats, as well as commercial administration of glibenclamide (II). Diabetic rats given yogurt with the addition of a combination of 3 herbal extracts (VI) and a combination of 2 herbal extracts (cinnamon +fenugreek seeds) (V) of 1% each showed better antidiabetic and hypolipidemic performances compared to the other groups (III, and IV). The combination of yogurt with some herbal extracts can add efficacy and value to the benefits of yogurt as a functional drink.

Abstract

Forage is the primary and cheapest source of fatty acids (FA), which includes conjugated linoleic acid (CLA), influencing milk FA. This study aimed to analyze the fermentation, digestibility, biohydrogenation, nutrient composition, and FA content of napier grass (NG) and king grass (KG). Grasses were collected from the Pangalengan (highland) and Dramaga (lowland) districts at three harvest ages (1, 1.5, and 2 months). The feed was then analyzed for nutrients and FA. An in vitro study was performed to analyze the concentrations of NH3, VFA, protozoa populations, and biohydrogenation. No significant differences were observed in protozoa, pH, total VFA, or FA biohydrogenation. NH3 ranged from 5.31 mM to 8.86 mM. Significant differences were found at different altitudes, with an interaction between grass type and harvest age and an interaction between the three factors. The highest NH3 concentration was found in rations containing highland NG at 1.5 months. The DMD value was 58.27%–64.39%, and OMD was 61.07%–67.18%. Different digestibility values were observed at different harvest ages, with an interaction between altitude and harvest age. This aligned with the CF, NDF, and lignin contents in grasses. The highest was at 1.5 months NG. Significant differences were observed in the relative proportions of propionic acids. The highest value was in the ration containing the 1.5-month highland NG. Rations containing KG yielded significantly higher amounts of the C18:0 and C18:1 trans. In conclusion, the 1.5-month highland NG is a potential ration for supporting healthier FA production in milk.

Abstract

This study aimed to estimate the genetic parameters for lactation milk yield (LMY), lactation fat yield (LFY), and lactation protein yield (LPY) in the Sahiwal cattle breed of Pakistan. Performance data of 3364 purebred Sahiwal cattle with 9964 herd test records were collected from the public and/or private herds. Various edits were applied, such as herd test day records < 3, unknown calving and drying dates, etc., which reduced the data set to 1039 animals with 4489 herd test records. Lactation yields for milk, fat, and protein were calculated using the test interval method. Preliminary data analysis was performed using PROC MIXED in SAS. The animal model under the REML method was used to estimate the genetic parameters of the milk yield, milk fat, and milk protein. A multivariate model (3-traits) was fitted, which included the fixed effects of parity besides random effects of herd-year-season of calving (HYS), animal and residuals for all three traits. Mean ± SD (kg) of LMY, LFY, and LPY were 1444.07±554.51, 60.48±25.18, and 48.26±19.39, respectively. Parity and HYS significantly varied (p<0.05) among cows for all investigated production traits. The estimates of heritabilities with their standard errors for LMY, LFY, and LPY were 0.164±0.065, 0.124±0.061, and 0.181±0.067, respectively. The phenotypic and genetic correlations were high among all three production traits, which ranged between 0.879 to 0.975 and 0.990 to 0.999, respectively, with standard errors ranging from 0.002 to 0.03. Low to moderate heritability estimates for milk component traits obtained in the present study suggest that these traits could be improved through genetic selection.

Abstract

Probiotics, prebiotics, and immunomodulators like β-glucan have become popular feed additives. Thus, this study examined the effects of a β-glucan product fortified with dietary biomaterials (fats, proteins, and minerals) on broiler chicks’ growth, carcass features, immunological response, white blood cell (WBC) count, and viable count (number of living cells) of lactobacilli. Day-old Ross-308 (n=250) were randomly assigned to 1 of 5 dietary treatments; A= basal diet, B= basal diet + 40 mg/kg of avilamycin, C= basal diet + 250 g/ton β-glucan product, D= basal diet + 500 g/ton β-glucan product, and E= basal diet + 750 g/ton β-glucan product. The starter diet was administered from days 1 to 14, the grower diet from days 15 to 21, and the finisher diet from days 22 to 35. Each treatment had 5 repetitions of 10 birds. On days 7 and 20, all birds were eye-drop inoculated against the Newcastle disease (ND) vaccine. Three chickens from each replication of all treatments were slaughtered on day 35 to examine carcass features and collect ileal digesta. White blood cell and viable lactobacilli counts at the end of the trial showed the effect of β-glucan supplementation. Throughout the trial, β-glucan administration did not increase average daily weight gain. The treatments did not change WBC or viable count; however, lactobacilli count increased (p≤0.05) in treatment group E. Treatment E increased (p≤0.05) ND-vaccination antibody-titers but did not affect immunological organ development. Treatment diet E (base diet +750 mg/t β-glucan product) improved broiler immunity and gut microbiota. In conclusion, the addition of β-glucan to broiler feed enhanced the beneficial gut flora, particularly Lactobacilli and immune response, and may serve as an alternative to antibiotics.

Abstract

Bone health in laying hens is associated with production performance and physical egg quality. This study aimed to evaluate the effects of a diet supplemented with Nutricell Eggstra (vitamin D3 enriched with canthaxanthin) on the production performance, egg quality, bone mineral, and immunity of laying hens. Herein, 150 Lohmann laying hens were divided into three treatments with five replicates. The treatment diets were: T1= diet without Nutricell Eggstra supplementation (control), T2= diet supplemented with 1.00 kg/ton Nutricell Eggstra, and T3= diet supplemented with 1.50 kg/ton Nutricell Eggstra. Compared to the control diet, supplementation of Nutricell Eggstra at doses of 1.00 kg/ton and 1.50 kg/ton significantly increased (p<0.05) hen day production, egg mass, egg index, yolk index, albumen weight, yolk color, eggshell thickness, eggshell strength, vitamin D3 content in egg yolk, heterophil, and heterophil/lymphocyte ratio. Supplementation of Nutricell Eggstra at the studied doses significantly decreased (p<0.05) the feed conversion ratio, yolk weight, eggshell porosity, and lymphocyte content. Nutricell Eggstra supplementation did not affect feed consumption, egg weight, albumen index, albumen weight, eggshell weight, Haugh unit, and tibia bone minerals. In conclusion, supplementation of 1.00 kg/ton Nutricell Eggstra yielded the best performance for Lohmann laying hens aged 36-39 weeks, while supplementation of 1.50 kg/ton Nutricell Eggstra produced the best quality eggs.

Abstract

This study aims to determine the impact of different GDF9 genotypes on feed intake, nutrient digestibility, and nitrogen balance in Kacang goats by examining various metabolic processes. Twenty-nine Kacang goats were genotyped using PCR-RFLP DNA at position g.3855A/C of the GDF9 gene in exon 2. A 2 × 2 factorial design with two factors, namely, diet type (diets 1 and 2) and genotype (homozygote AA and heterozygote AC), was adopted. Diet 1 group comprised 11 goats with the AA genotype and 4 goats with the AC genotype, and the diet 2 group consisted of 9 goats with the AA genotype and 5 goats with the AC genotype. Both diets had the same protein content (iso-protein) and consisted of free-choice Napier grass (Pennisetum purpureum). Diet 1 had an additional 400 g of concentrate containing 11.25% crude protein (CP) and 55.86% total digestible nutrients (TDN). Diet 2 was a total mixed ration (TMR) containing 12.46% crude protein and 67.92% TDN. Results demonstrated a significant interaction (p<0.05) effect between diet and genotype on crude protein (CP) digestibility, neutral detergent fiber (NDF) digestibility, fecal nitrogen (N feces), urinary nitrogen (N urine), nitrogen retention (%), and blood urea nitrogen (BUN). However, no significant interaction effect was observed on the consumption of dry matter (DM), CP, crude fiber (CF), nitrogen free extract (NFE), and NDF and the digestibility of DM, CF, and NFE. TMR resulted in a 9% higher consumption of NDF, higher nutrient digestibility, improved nitrogen balance, average daily gain (ADG), and elevated glucose levels compared with diet 1. Kacang goats with the AC genotype exhibited better CP digestibility and increased nitrogen intake than those with the AA genotype. In conclusion, the GDF9 genotype influences the nutrient digestibility in Kacang goats, and those with the AC genotype utilize feed nutrients more efficiently than those with the AA genotype. The AC genotype resulting from the GDF9 gene mutation at position g.3855A>C can be used for genomic marker selection of high-quality Kacang goats in nutrient digestibility.

Abstract

Fatty acid (FA) composition is the principal measure of the nutritional quality of fats in balut (i.e., boiled fertilized eggs from mallard ducks) that may affect human cardiovascular health. This study aimed to compare the fat content, FA composition, and nutritional indices/ratios concerning the edible components of 15-day old balut (B15d) and 18-day old balut (B18d) produced by Itik Pinas duck breeds (IP-Itim, IP-Khaki, and Kayumanggi-IP– an “IP-Khaki × IP-Itim” F1 cross) in the Philippines. A total of 275 pooled samples of the embryo, yolk, albumen, and fluid portion from 154 B15d and 175 B18d balut eggs were analyzed for fat content and FA composition by gas chromatography. Fat content was highest in the yolk (29.59%), followed by the embryo (1.63%) and negligible in both albumen and fluid portions. The major FAs with the highest proportion by weight of total FAs in the solid components of balut were oleic acid C18:1n-9 (20.7%–43.8%), palmitic acid C16:0 (12.0%–24.5%), stearic acid C18:0 (2.7%–8.9%), and linoleic acid C18:2n-6 (3.5%–6.9%). The fluid portion was dominated by arachidonic acid C20:4n-6 (18.8%), trans-vaccenic acid C18:1n-7 (17.6%), oleic acid (9.0%), and palmitic acid (8.3%). Total saturated FAs (SFA) were higher in the embryo than in the yolk. However, monounsaturated FAs (MUFA) and polyunsaturated FAs (PUFA) were higher in the yolk than in the embryo. Total SFA was higher, while total MUFA and PUFA were lower in B15d balut than those in B18d balut. Since SFAs are considered unhealthy compared to MUFAs and PUFAs, the yolk from B18d balut produced by Kayumanggi-IP ducks appears to have greater health benefits due to its lower atherosclerotic and thrombotic potential and higher health-promoting index and hypocholesterolemic/ hypercholesterolemic ratio.

Abstract

The study aimed to evaluate the effects of dietary soybean oil (SO) substitution with Sacha inchi oil (SIO) supplemented with herbal plants (HP, Bidens pilosa, Angelica sinensis, and Ramulus cinnamomi) on growth performance, carcass characteristics, and pork quality parameters. A total of 144 Duroc × (Landrace × Yorkshire) crossbred pigs (63.1 ± 0.4 kg) were randomly allocated to one of the three dietary treatments: a basal diet containing 2% SO without HP (CONT), a basal diet containing 1% SO, 1% SIO and 1% HP (TRT1), and a basal diet containing 2% SIO and 1% HP (TRT2). Each treatment includes 4 replicate pens containing 12 pigs, balanced by sex and body weight. The experiment lasted for 70 days. The results show no effects of the dietary treatments on average daily gain, average daily feed intake, and feed efficiency. Likewise, there were no differences in carcass moisture losses, lean percentage, pH, and colors between the dietary treatments. The pigs fed the SIO diets with HP had lower backfat thickness (p=0.02) than their counterparts fed the SO diet. In pork, a significant decrease in lipid and cholesterol, and an increase in polyunsaturated fatty acids (PUFA), especially omega-3 and omega-6, were found (p<0.01) in the SIO groups when compared to the control one. The PUFA percentage increased linearly with the levels of SIO. In conclusion, replacing SO with SIO associated with HP did not affect animal performance but produced a leaner carcass and upgraded pork quality.
