Objective: This study aimed to use the potential chitosan processing waste from shrimp heads as a premix to improve the production performance of laying chickens. Materials and Methods: This research uses shrimp head waste, NaOH, hydrochloric acid, Na2SeO3, and NaCl solutions. Processing shrimp head waste into chitosan is done in three ways, namely demineralization, deproteination, and deacetylation. Each of the resulting liquid wastes is then mixed until a neutral mixture is obtained. The data observed were the nutrient and amino acid content of liquid waste from the deproteinization, demineralization, and deacetylation processes, as well as the neutral mixture. Results: The results showed liquid waste from the process of making chitosan from shrimp head waste using deproteination, demineralization, and deacetylation methods, as well as a neutral mixture containing little energy, protein, and fat but is rich in minerals. The most abundant and complete amino acid content is found in deproteination process wastewater and neutral mixtures. Conclusion: In conclusion, the waste from making chitosan from shrimp head waste through deproteinization, demineralization, and deacetylation, and the neutral mixture contains enough minerals and amino acids needed by livestock, so it has the potential to be used as a premix.

Objective: This study aimed to assess Aerodramus fuciphagus (Thunberg, 1812) nest’s mineral content, cytotoxicity effects, and antioxidant activity. The Edible birds’ nests (EBNs) were obtained from Tanah Merah (TM), Tumpat (TU), and Jeli (JE) districts in Kelantan, Malaysia. Materials and Methods: The mineral content was assessed via inductively coupled plasma mass spectrometry. The cytotoxicity effect was evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide and brine shrimp lethality assays. The antioxidant activity was investigated by 2,2´-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and ferric-reducing antioxidant power (FRAP) assays. Results: Valuable macro- and microelements, including sodium, potassium, aluminum, calcium, magnesium, zinc, iron, and selenium, were detected in the EBN samples. The cytotoxicity test revealed that JE hydrochloric acid (HCl) extract had promising efficacy against HeLa cell lines, with IC50 values of 20.00 ± 0.57 µg/ml. Similarly, TU sodium hydroxide (NaOH) extract inhibited the proliferation of MCF-7 cell lines (IC50 0.03 ± 0.01 µg/ml). Based on the BSL assay, the EBNs were considered safe for consumption as the LC50 values of all the samples were below the toxic level (>1,000 µg/ml). TM EBNs aqueous, TU aqueous, and HCl extracts showed promising antioxidant activity at IC50 values (10 µg/ml) in the DPPH assay. However, the NaOH extract from TU exhibited the highest FRAP value (1.38 ± 0.00 mM gallic acid equivalents gm⁻¹) compared to all other extracts. Conclusion: This study’s findings demonstrated the potential of EBN as an alternative anticancer agent and natural antioxidant. J. Adv. Vet. Anim. Res., 12(1): 132–140, March 2025 http://doi.org/10.5455/javar.2025.l880

Objectives: The primary objective of this study is to provide a comprehensive analysis of the differences between conventional and brown midrib (BMR) sorghum in terms of biomass, nutrient quality, nutrient digestibility, and animal performance. Materials and Methods: A comprehensive database was created by integrating 73 datasets from 29 articles. The different studies were denoted as random effects, while the BMR sorghum variety was described as a fixed component. Afterward, these two aspects were calculated utilizing a linear mixed model. Results: According to the findings of the present meta-analysis, conventional sorghum produces higher quantities of forage and grain biomass in comparison to BMR (p < 0.001). As expected, BMR sorghum has a lower content of neutral detergent fiber (NDF), acid detergent fiber, and lignin compared to conventional sorghum (p < 0.001). The digestibility of BMR sorghum performed better than conventional sorghum (p < 0.001), especially for NDF digestibility (54.98% vs. 47.37%). BMR shows suitability as a fodder option for dairy cows due to its superior milk yield compared to conventional sorghum (15.04 vs. 14.06 kg/day; p < 0.01). Conclusion: In conclusion, BMR sorghum produces higher biomass compared to conventional sorghum. Nevertheless, in terms of nutrient quality and digestibility, BMR sorghum is the most optimal choice. The results will significantly improve animal performance. J. Adv. Vet. Anim. Res., 12(1): 157–168, March 2025 http://doi.org/10.5455/javar.2025.l883

Objective: This study aims to assess the impact of aging time on the quality of meat, fatty acid profiles, and volatile compounds in cooked Thai native beef. Materials and Methods: The experiment utilized a randomized complete block design, where the aging time (0, 7, 14, 21, and 28 days) served as the treatment and the longissimus thoracis et lumborum muscle from Thai native cattle (n = 4) was considered a block. Results: Meat color and Warner-Bratzler shear force values decreased as the aging time increased. Furthermore, the moisture content decreased while the protein and ash content increased with a longer aging time. The proportions of fatty acids showed significant differences with varying aging times. These fatty acids exhibited the highest proportions in the 14-day dry-aged beef samples. The levels of short-chain aldehydes (pentanal, heptanal, octanal, nonanal, decanal, and 2-nonenal) and alcohols (1-hexanol and 1-octanol) decreased as the aging time increased. However, there was an increase in long-chain aldehydes (tetradecanal, hexadecanal, heptadecanal, and octadecanal) with longer aging time. In addition, the levels of toluene, dodecane, tridecane, methyl-pyrazine, 2,5-dimethyl-pyrazine, trimethyl-pyrazine, and dimethyl trisulfide were higher in 14-day dry-aged beef compared to beef that had not been aged. Furthermore, a correlation was found between the number of the 6 significant fatty acids in the dry-aged beef samples and the 12 volatile compounds in cooked beef. Conclusion: Our results suggest that aging times significantly influence the fatty acid profiles of Thai native beef, which in turn are correlated with the characteristic volatile compounds. J. Adv. Vet. Anim. Res., 12(1): 179–191, March 2025 http://doi.org/10.5455/javar.2025.l885

Objective: The objectives of this study are to measure the body weight (BW) and morphometric parameters of Napu buffaloes, identify the growth hormone (GH) and insulin-like growth factor-1 (IGF-1) gene polymorphisms, and associate them with the BW and morphometric parameters of Napu buffaloes. Materials and Methods: This study used 39 Napu buffaloes (9 males and 30 females). Morphometric measurements were performed using a measuring tape. The GH and IGF-1 gene diversity analysis was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct sequencing techniques. Results: The results showed that there is diversity in BW and body size of Napu buffaloes due to the influence of age and sex. The results of PCR-RFLP analysis of the GH|AluI gene showed 0% VV, 100% LL, and 0% VL genotypes. While the IGF-1|SnaBI gene shows the genotype AA 0%, BB 100%, and AB 0%. The sequencing results of the GH and IGF-1 genes in Napu buffaloes did not find mutations. Conclusion: Age and sex in Napu buffaloes may affect BW and body size. The GH and IGF-1 genes in Napu buffaloes are monomorphic, so no association can be made with the morphometric parameters of Napu buffaloes. J. Adv. Vet. Anim.

Objective: The present study was designed to conduct molecular and morphological identification of cat fleas (Ctenocephalides felis) from Bangladesh along with nucleotide polymorphism and phylogenetic analysis. Materials and Methods: Samples were collected from two hosts (cat and human). The species was identified through morphological studies first, and then DNA was extracted for subsequent molecular analysis. A part of the mitochondrial 16S rRNA gene was amplified by polymerase chain reaction using extracted DNA as a template. The amplified region was sequenced using the Sanger dideoxy method. The sequence was subjected to NCBI BLASTn search. BioEdit and MEGA 11 software were used for multiple sequence alignment (MSA) and generating a phylogenetic tree. Results: Morphological features such as shape, size, and appendages showed similarity with C. felis. The metatibial formula of chaetotaxy (2-2-2-2-1-3) was confirmed for species-level identification. NCBI BLASTn search showed the highest sequence identity with the available sequence of C. felis such as 99.78% (NC_049858.1) and 99.12% (MW420044.1 and MK941844.1) with 100% query coverage. MSA of C. felis sequences from different geographical distributions show their sequence affinities with each other, and the phylogenetic tree presents their relationship with each other. Conclusion: Both morphological and molecular studies clearly indicate the identity and confirmation of cat flea (C. felis) from Bangladesh. J. Adv. Vet. Anim.

Objective: This study aims to investigate the hepatoprotective, anti-inflammatory, and wound-healing potentials of spirulina utilizing a rat model. Materials and Methods: Carbon tetrachloride (CCl4) was used to induce hepatotoxicity, while carrageenan was employed to induce hind paw inflammation. The wound healing capability was assessed by making a 6 mm round wound with a biopsy punch on the dorsal interscapular area of each rat. The animals were fed a diet mixed with spirulina at dosages of 250 and 500 mg.kg−1bwt. Paw thickness measurements were taken at 1, 3, and 6 h after carrageenan injection. Results: Intraperitoneal injection of CCl4 leads to hepatotoxicity, as evidenced by significantly elevated serum levels of alanine aminotransferase and aspartate aminotransferase. Treatment with spirulina markedly reduced these biochemical markers. CCl4 -induced hepatic cellular necrosis, central vein congestion, and steatosis were notably improved following spirulina administration. Additionally, spirulina treatment diminished paw edema and shortened wound closure time in a dose-dependent manner. Histopathological analysis of the inflamed paw revealed massive infiltration of inflammatory cells and thickening of the epidermis, both of which showed significant improvement with spirulina treatment. The anti-inflammatory and wound-healing effects of spirulina were comparable to those of indomethacin, an established anti-inflammatory drug. Conclusion: Our findings demonstrate that Spirulina platensis possesses beneficial properties in counteracting hepatotoxicity and inflammation. Additionally, it exhibited significant wound-healing effects in rat models. These results reinforce the potential health advantages of spirulina as an effective functional food. J. Adv. Vet. Anim.

Objective: The common coot (Fulica atra) is a medium-sized migratory bird wintering at different wetlands in Pakistan. It belongs to the order Gruiformes and family Rallidae. This study aimed to investigate the morphometry, hematology, and blood chemistry of common coots during the winter visit of 2022–2023. Materials and Methods: Thirty-two adult common coots were captured with the help of hunters holding valid licenses from six wetlands in Punjab, Pakistan. Each individual was sexed and subjected to different morphological measurements. Eighteen blood samples (3–5 ml) were collected from the basilic veins of adults for hematology and blood chemistry. Results: Results revealed that body weight ranged from 378 to 680 gm, with males significantly heavier than females. Length was not significantly different. Males showed dominance in most of the morphometric characteristics compared to females. Regarding hematological parameters and plasma chemistry, there was a sufficient difference between the genders in most of the studied parameters. Conclusion: The male coot was significantly larger compared to the female, except for total length. Hematology and plasma chemistry showed significant differences between genders. J. Adv. Vet. Anim.

Objective: The aim of this study was to estimate genetic parameters, breeding value, and ranking of Holstein Friesian × Local (HF × L) crossbred sires based on multi-trait selection index information. Methods: A total of 51 HF × L crossbred breeding bulls of three different genetic groups (50%HF × 50%L, 62.5%HF × 37.5%L, and 75%HF × 25%L) managed at Central Cattle Breeding and Dairy Farm (CCBDF) were evaluated based on 4,319 half-sib progeny performance data. The descriptive statistical analysis was performed using the R package. Genetic parameters were estimated using BLUPF90 by a single-trait animal model. A selection index was constructed using adjusted breeding values multiplied by variable economic weightage for each trait. Results: Genotype had significant effects on the investigated semen quality attributes (p < 0.05), where 75%HF × 25%L and 62.5%HF × 37.5%L crossbred genotypes both differed significantly from 50%HF × 50%L crossbreds (p < 0.05). In general, better productive and reproductive performances were found with the progression of HF inheritance. Daughters of 75%HF × 25%L crossbred bulls showed the highest average performance in birth weight (27.20 ± 0.09 kg), daily milk yield (8.55 ± 0.06 l), peak milk yield (10.44 ± 0.07 l), and lactation length (233.53 ± 0.85 days). The study investigated variance components of eight productive and reproductive traits such as the birth weight of calf, age at first conception, service per conception, daily milk yield, peak milk yield, lactation length, and calving interval where estimated heritability ranged from 0.09 to 0.32. Genetic correlations among the considered traits were found to be mostly weak. Among the top 20%, breeding bulls belonged to 75%HF × 25%L and 62.5%HF × 37.5%L crossbred groups. Conclusion: This study provides insightful information on the genetic evaluation of different graded bulls that could be the basis for the proven crossbred breeding bulls’ selection process at CCBDF.  J.
