DETECTION AND CHARACTERISATION OF MICROPLASTICS IN ANIMAL FEED
Microplastics (MPs) the products of plastic breakdown, are entering the environment as a result of plastic abuse, which are of size less than 5mm. Due to their ubiquitous nature, MPs have become a significant environmental concern. One alarming area of MPs contamination is their potential presence in the feed of edible animal species. Growing research suggests that MPs can enter food products and subsequently move to various trophic levels of food chains. Hence, assessing the threat of MPs contamination in animal feed is important for food security and human health. In this investigation, 36 livestock and poultry feed samples were collected from 12 different farms, MPs were detected using Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimeter (DSC). The Nano particle analyser was used to determine the size distribution, and Pyrolysis-GC/MS was used to quantify MPs. According to the findings, all the feed samples contained a significant amount of Polyethylene terephthalate (PET), Polypropylene (PP), and Polyvinyl chloride (PVC) and the particle size ranged from 2.02 to 10.7 μm. Present study has given detailed information on the size distribution of MPs in animal feed, which is thought to enable them to pass through membrane barriers. From the findings it is evident that there are high chances of MPs entering animal feed due to the continuous contact of the feed with plastic-based materials. These MPs can accumulate in the tissues of animals and potentially be transferred to humans through the consumption of meat, milk, and other animal-derived products. Subsequently these MPs can finally bio-accumulate in humans and cause serious health issues. © 2023, Scienceline Publication. All rights reserved
Observational Study on Reproductive Behavior in Semi-Wild Sambar Deer (Rusa unicolor) for Wildlife Conservation and Assisted Reproductive Management
Understanding the reproductive behaviors of different wildlife species is essential to unravel their reproductive strategies, ecological adaptations, and conservation requirements. This study delved into the reproductive biology of the sambar deer (Rusa unicolor), with a focus on promoting assisted reproductive technology for wildlife conservation and investigating the reproductive behaviors of male and female sambar deer. The study was conducted at Pusat Konservasi Hidupan Liar (PKHL) Sungkai, Perak, Malaysia. The observation focused on one male and two female sambar deer. Direct observations of the deer were conducted for 14 days in September 2022. The direct observations were performed in the morning (Session 1= 8-10 am), afternoon (Session 2 = 10-12 pm), and evening (Session 3= 3-5 pm), using the instantaneous sampling method. A total of 75 behavior instances were recorded, in which male deer exhibited the most reproductive behavior at 58 instances (77.3 of the total reproductive behavior). Successful mating was observed on day 6, elucidating a crepuscular preference in the male animal in exhibiting reproductive behavior. The female�s reproductive behavior lasted for a short period, from 24 hours for Female 2 and 72 hours for Female 1. In conclusion, there was a distinct behavior between the male and female deer during the rutting season. Understanding the reproductive behavior to estimate the length of estrus can be useful as a non-invasive tool to detect heat and can be considered to improve breeding management and implement assisted reproductive technology. © The Author(s) 2023.

Improving the Quality and Nutritional Value of a Mixture of Sago Pith and Indigofera Leaves Fermented with Rhizopus oligosporus
The nutritional value of sago pith is limited due to its low protein content, making it less suitable for poultry feed. To increase the benefit values of the sago pith, it is necessary to process it through fermentation. The current study aimed to determine the effects of substrate composition and fermentation time of fermented sago (Metroxylon sagu) pith (SP) and Indigofera (Indigofera zollingeriana) leaves (IL) mixture using Rhizopus oligosporus as an inoculum on crude protein, crude fat and crude fiber content of fermented SP and IL, nitrogen retention, crude fiber digestibility, and energy metabolism in broiler chickens. The study was performed on 30 broiler chickens, average weighing ± 1.5 kg at 6 weeks of age, along with SP, IL, and R. oligosporus. This experiment was conducted using a randomized design in a 3x3 factorial with three replications. Substrate composition, or factor A, was made up of A1 (80 SP + 20 IL), A2 (60 SP + 40 IL), and A3 (50 SP + 50 IL). Fermentation time as Factor B entailed B1 (2 days), B2 (3 days), and B3 (4 days). The findings demonstrated a significant interaction between the time of fermentation and the composition of the substrate in relation to crude protein content, nitrogen retention, crude fat, crude fiber digestibility, and energy metabolism. It can be concluded that the composition of substrate 50 SP and 50 IL with 3 days of fermentation yielded the best result, with crude protein at 25.45, nitrogen retention at 59.72, crude fat at 0.020, crude fiber at 6.40, crude fiber digestibility at 57.34, and metabolic energy at 2658.44 kcal/kg. © The Author(s) 2023.

A Pathologic Case of Gout Tophi Deposition with a Concurrent Systemic Bacterial Infection in a Leopard Gecko (Eublepharis macularius)
Gout is caused by excessive uric acid in the blood deposited in tissues (visceral gout) or joints (articular gout), leading to severe inflammation and pain. A female leopard gecko was presented to the University Veterinary Hospital, University of Putra, Malaysia, with a history of swelling at the left caudal mandible, inappetence, and weight loss. An oral examination indicated a swollen mouth with scabs on the upper right mandible and multiple whitish deposits inside the mouth. The preliminary diagnosis was mouth rot, and the treatment included metronidazole and a multivitamin supplement. The leopard gecko died 12 days after treatment since there was no improvement. Post-mortem examination revealed that the liver was slightly enlarged with generalized moderate congestion and the presence of whitish deposits, as well as noticeable whitish deposits on the pleural surface of the lungs. Histopathological examination of the lungs revealed a granuloma with an inflammatory reaction predominantly by abundant mononuclear cells and fibrin deposition. An irregular collection of amorphous materials in the visceral pleura suggested gout tophi. The liver was infiltrated with amorphous material and fibrinous tissue, and it had mild congestion, indicating visceral gout and bacterial infection. Klebsiella pneumoniae and Proteus mirabilis were isolated from the lungs and liver samples, respectively. In conclusion, gout tophi is common in reptiles, but visceral involvement is rare, and early detection is critical to avoid secondary bacterial infection, as demonstrated in this case. © Open Access: This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.

Effects of Partnership Patterns on Broiler Chickens’ Performance in the Agribusiness System of Indonesia
The partnership system is standard broiler cooperation in Indonesia. This system influenced agribusiness performance. Hence, the current study aimed to analyze the broiler agribusiness system in Kediri Regency, Indonesia, addressing three main areas, including partnership patterns, production performance, and financial performance. In this study, data was gathered from participants using a cross-sectional survey approach, capturing information from individuals at a specific moment in time. The research was performed from July to September 2022, utilizing both primary and secondary data. Primary data was obtained through direct observations and interviews with relevant stakeholders, while secondary data was sourced from various databases, such as the Indonesian Statistical Bureau and the Agriculture Ministry of Indonesia. Both types of data were subjected to quantitative descriptive analysis. The results indicated that the broiler partnership pattern consisted of three subsystems, including the chicken production facility providers (day-old chicks, feed, and medicines), the farming unit responsible for production process management (housing, feeding, drinking, and biosecurity), and the marketing subsystem focusing on chicken prices). The farmers in the farming unit showed effective production performance with a feed conversion ratio of 1.69, an index performance of 307, and an average body weight of 2.03 kg/head. Moreover, the farmers demonstrated a profitable financial performance with the revenue-cost ratio exceeding 1, reaching 1.07
Effects of Black Pepper, Turmeric, and Fennel on Essential and Non-essential Chemical Contents of Egg
The use of essential oils (EOs) in animal feeding has gained attention as a potential antibiotic growth promoter replacement over the past two decades. The current study aimed to determine the impact of three feed additives, namely black pepper, turmeric, and fennel, on the productivity of laying hens, the chemical composition, and macro and microelement content in layer eggs. A total of 280 chicks aged 75 days were randomly divided into 7 treatments (5 replicates of 8 chicks). One treatment group was provided as the unsupplemented control. The other six treatment groups, namely D0 (basal diet BD control), D1 (BD + 1% of black pepper), D2 (BD + 1% of turmeric), D3 (BD + 1% of fennel), D4 (BD + 0.5% of black pepper + 0.5% of turmeric), D5 (BD + 0.5% of black pepper + 0.5% of fennel), D6 (BD + 0.5% of turmeric + 0.5% of fennel) were supplemented with varying levels of phytobiotics. The result of the study indicated that the egg weight, Hen-day-production (HDP), egg quality, and haugh unit significantly improved with a combined supplementation of phytobiotics (D4, D5, and D6 diets) when compared with the control. However, there were no significant differences in the chemical composition of eggs. The X-ray fluorescence spectrometer analysis of eggs revealed the presence of 17 significant elements, including phosphorous, sulfur, chlorine, potassium, calcium, manganese, iron, copper, zinc, and bromine. The study findings showed that the combined supplementation of phytobiotics lowered K and Cl, whereas Zn, Ca, S, and Cu contents positively increased in hen eggs by including phytobiotic in the diet. In conclusion, the EOs of phytobiotics as dietary supplementation at 1% and 0.5% could improve the HDP, egg weight, and egg mass, including nutrient elements in the egg. © 2023, Journal of World''s Poultry Research.

Effects of a Vitamins D and C Supplement on Performance, Hatchability, and Blood Profiles of Broiler Breeders
Vitamin D is a fat-soluble vitamin that plays a crucial role in controlling Calcium and Phosphor homeostasis, bone mineralization, and modulation of immune responses. Vitamin C is a cofactor of enzymatic reactions with anti-inflammatory and antioxidant properties to prevent and repair damage to cells in the body from exposure to free radicals and the immune system. The current study aimed to investigate the effects of dietary supplementation of 25(OH)D3 with vitamin C at different doses on broiler breeders� blood profile, egg quality, and hatchability. The adaptation process before collecting the data was 2 weeks. A total of 6200 females and 620 male broiler breeders in the laying period aged 32-46 weeks were divided into 4 treatment groups with 5 replicates (each peach contained 310 female and 31 male breeders). The treatments included control as T0 (0 g/ton Nutricell HyC®), T1 (100 g/ton Nutricell HyC®), T2 (200 g/ton Nutricell HyC®), T3 (400 g/ton Nutricell HyC®) supplemented in feed. The observed variables were performance in breeding farms and hatcheries. The treatments with experimental doses indicated significant differences in the performance of broiler breeders, including feed intake, body weight, egg weight, egg mass, hen day production, hen house production, feed conversion ratio, and parameters of blood profile. The results showed a significant difference between the treatments and the control group in terms of hatch performance, clear eggs, exploding eggs, hatchability eggs, fertile eggs, salable chicks, and hatching of fertile eggs. However, no significant effects on fertility, culling of chicks, and embryonic mortality in the treatment groups were indicated. In conclusion, Nutricell HyC® with a dose of 400 g/ton in feed has indicated the best result in breeding farm and hatchery performance of broiler breeders in the laying period. © 2023,Journal of World''s Poultry Research.

Poultry Management Strategies to Alleviate Heat Stress in Hot Climates: A Review
Heat stress remains a major challenge affecting poultry production in sub-tropical and tropical environments; hence it continues to receive attention. The present study aimed to discuss heat stress and its effects on poultry production and suggests mitigation strategies to combat the effects of increased environmental temperature on poultry performance. Poultry raised in hot climates suffers from heat stress, which reduces meat and egg production, reproductive performance, feed intake, and feed conversion efficiency leading to poor growth rates. Reduced feed intake results in a reduction in meat quality, growth, egg yield, and quality. A decrease in feed utilization efficiency is the major cause of poor growth performance in hot environments. To counteract the negative impacts of high ambient temperatures on the performance of poultry, a wide range of management practices are widely used, including nutrient manipulations (particularly protein and energy), electrolyte and vitamin supplementation, feed form (especially particle size and moisture content), choice feeding, controlled feeding, time of feeding, wet feeding, water management, and use of new breeds that thrive well in hot environments. These management practices help lower heat load and facilitate evaporative cooling, all of which may positively impact poultry performance and health. © 2023,Journal of World''s Poultry Research.
