Whole meal bread made up from whole grains mostly consumed due to health purpose. The aim of this study was to determine the effect of processing technique on physical (colour, moisture content, pore size, texture and specific volume) and organoleptic properties of whole meal bread. Three treatments which B1, B2 and B3 of whole meal bread were prepared which represent the processing technique straight dough, sponge and dough, and sourdough, respectively. Whole meal bread between B1 and B2 with B3 showed significant (p < 0.05) increased in density (276.58, 270.35, 647.84 g/cmᶾ), hardness (747.16, 747.16, 2425.75 g/cmᶾ) and chewiness (495.71, 519.98, 2843.73 g) respectively. Variations were observed for crumb (internal) and crust (external) colour from 33.77 to 39.63 (L-value), 3.08 to 9.80 (a-value) and 25.38 to 10.82 (b-value), 23.65 to 27.94 (L-value), 2.27 to 2.95 (a-value), 9.26 to 13.11 (b-value) respectively. Hence, straight dough method produced whole meal bread with higher value of specific volume (3.58 cmᶾ/g), moisture content (24.66 %), lightness of crumb (23.65) and chewiness (495.71 g). Thus, results showed that straight dough method was the most efficient and acceptable method for bread baking process in order to get the good physical and organoleptic properties of whole meal bread.

Milk is an important elements due to its high nutritious and balanced in human diet. In Asian, goat milk is the most consumed because of the unique taste, more nutritious than cow milk. However, milk production and composition values differ at every stage of lactation in goats. Thus, determining the highest milk production and producing the best quality goat milk is essential to satisfy the local market demands. The objective of the present study is to determine the milk yield and milk composition at different lactation stages and to evaluate the lactation curves in Saanen goats. The lactation stages can be categorized into three, early (less than 80 days), mid (80 – 140 days) and late (over 140 days) days in milk (DIM). In total, 90 milk samples were collected from 15 goats representing early (n=5), mid (n=5), and late (n=5) stages of lactation. The Saanen goats were raised under the same conditions, and milking was done early in the morning (9.00am).The milk yield from Saanen goats were collected and measured weekly at each stage of lactation. Milk samples were analyzed for fat, protein, solid non-fat, and lactose. Current result illustrated, there were significant different (p ˂ 0.05) among three stages of lactation in milk yield, solid non-fat, fat, protein and lactose. In terms of food regulation, the Saanen goats almost fully met the standard requirements for milk production and composition. In addition, this study also observes the lactation curves in Saanen goats and analyse the curve shapes and patterns. The average milk yields from three different stages develops a concave downward curve. The results indicated that mid yield increased from early to mid- lactation and decreased thereafter until the end of lactation.

This study was conducted to evaluate raw and pasteurized cow milk regarding physical properties, microbiological quality, and lethality value ofMycobacterium Paratuberculosis(MAP)at different temperature and time combinations of the pasteurization process.Cow milk samples were pasteurized at high-temperature (70°C, 75°C, and 81°C) and short-time (15s and 25s) high temperature and short time (HTST) combinations. Raw and pasteurized (HTST) cow milk was analyzed, while commercial cow milk that undergo proses (HTST) was used as control. High-temperature short time (HTST) pasteurization showed a significant effect on the colour of raw and pasteurized cow milk (p<0.05) at every temperature. In addition, cow milk also indicated an increase in lightness and yellowness after HTST pasteurization.The microbiological quality of raw, pasteurized, and commercial cow milk is evaluated using the Methylene Blue Reduction (MBRT) test, a common, rapid, simple, and inexpensive method for microbiological quality evaluation.The MBRT on raw milk samples revealed that it was of poor quality. On the other hand, all pasteurized samples were good quality, and the commercial sample was excellent.Based on the evaluated F-values, the most suitable temperature and time combinationsin this study was 70°C and 25s.

Tridax procumbens and Asystasia gangetica are extensively prevalent and can be found from tropical Asia to Africa. Both plant samples were found to have a high nutritional value, especially in protein, and to be highly attractive to ruminants. Therefore, the objectives of the study were to measure and compare the nutrient composition of Tridax procumbens and Asystasia gangetica in terms of the nutritional value for ruminants. Both plants samples were collected at Besut campus, University of Sultan Zainal Abidin. The samples were then washed under tap water to remove foreign matter such as soil to prevent soil contamination in the analysis. Then, the samples were dried in a furnace below 60 - 70˚C and crushed prior to further analysis using proximate analysis. Seven parameters were measured using proximate analysis, which included dry matter (DM), moisture, ash, crude protein (CP), crude fiber (CF), ether extract (EE), and nitrogen-free extract (NFE). The findings in this study show that A. gangetica had significantly higher (p < 0.05) in dry matter (DM) (18.84%), crude protein (CP) (22.27%), and nitrogen-free extract (NFE) (50.25%). However, T. procumbens showed the highest nutrient in moisture (88.70%), ash (12.15%), crude fibre (CF) (25.01%), and ether extract (EE) with 3.71%. Thus, this study revealed that A. gangetica to have a higher potential to be used as an animal feed than T. procumbens.

Flies are common ectoparasites to livestock. Some species of flies are important to small ruminants because they can spread disease and cause disturbance to animals, thus lowering their productivity. Considering the impact of flies to the productivity of small ruminants, it is important to identify the species of flies that occur in an area for early control actions. The study was aimed to determine the species of flies in Diptera family that occur in Ladang UniSZA Pasir Akar and their population abundance. The flies were collected using three types of traps: Malaise trap, yellow pan trap and yellow sticky trap for three consecutive weeks. The traps were set up in three different locations in small ruminants rearing area in the farm. Nine Diptera families significant to livestock were identified: Calliphoridae, Ceratopogonidae, Culicidae, Muscidae, Psychodidae, Rhiniidae, Sarcophagidae, Simuliidae and Tabanidae. The family Sarcophagidae recorded the highest abundance in the farm (26.57%), while the lowest of flies count was from the family Tabanidae (0.82%). The most diverse family of Diptera was collected by Malaise trap and the lowest diversity was recorded from yellow pan trap. The results from this study had provided the first insight of the flies important to small ruminants occurred in this farm.

Skeletal deformities in cultured fish are known worldwide and it had affected the survival, growth and appearance of the fish which contribute to production loss. Clarias gariepinus is known as number one farmed fish in Malaysia. C. gariepinus also effected in these deformities especially in cultured species. The objectives of this study are to identify the skeletal deformities that occur in juvenile stages and to compare the bone structure between the normal and deformed fish. A total of 50 juveniles’ fish were collected from Aquaculture Extension and Community Centre Machang, Kelantan. The juvenile was measured before undergo staining process. The fish were starved for one day then fixed in 70% ethanol for two weeks. The fish were then stained with alizarin red S for cartilage and Alcian blue for bone. The specimens were photographed in order to observe the deformities. The data showed only 13.0% juveniles have skeletal deformities, 10.9% with lordosis and 2.2% scoliosis. The cause of the deformities may be due to the heterogenous growth but other factors might also contribute to the problem. As the conclusion, the skeletal deformities observed in juvenile C. gariepinus were detected with the whole-mount staining method ranged from size 7.3 and 26.0 cm in total length. This study shows there is heterogenous growth rearing at low percentage even from skilled farm. Further study should concentrate on hidden factors that affected the deformity rate and mineralization of the juvenile fish.

Setaria sphacelata is a high and most prevalent tropical grass, while Cleome gynandra is a tropical annual herb which commonly used as vegetables in Africa and Asia. Both plant samples were found to be high in nutritive value especially in protein and very appetizing in ruminants. The main objectives of the study were to measure and compare the nutritional composition of Setaria sphacelata and Cleome gynandra as a function of their nutritional value for ruminants. The two plant samples were collected near the Tembila area, Besut Terengganu. The samples were dried in a furnace below 60 - 70 ˚C and crushed prior to further analysis using proximate analysis. Proximate analysis was used to measure values for moisture, dry matter (DM), ash, crude protein (CP), crude fibre (CF), ether extract (EF) and nitrogen-free extract (NFE). The result of this analysis shows that Cleome gynandra had much higher crude protein (CP) (p < 0.05) at 36.86% and ether extract (EF) at 5.50%. Crude protein (CP) is one of the most essential nutrients that ruminants need. Therefore, this study found that Cleome gynandra contains a higher nutritional value in terms of crude protein (CP) than Setaria sphacelate, which can be used as a feed for ruminants.

Water is the most crucial element for living organisms as a component for survival. Even water has become the habitat for some organisms. Therefore, assessment of water quality is vital to keep water in good condition. This study aimed to determine the water quality of Besut Campus Lake by assessing the physicochemical parameters. Water Quality Index (WQI) is related to the process of determining the status class of water according to beneficial use, with a higher index value indicate good water quality. National Lake Water Quality Standard (NLWQS) was also applied in determining the category of enclosed water systems like ponds and lakes. Water samples were taken from sampling stations at Besut Campus Lake and undergo in – situ and ex–situ analyses involving nine physicochemical parameters. In addition, heavy metal analyses were conducted in the laboratory according to American Public Health Association (APHA) methods. Based on the research conducted, Besut Campus Lake was classified as Class Ⅱ with an index value of 78.23 from the Malaysia Water Quality Index (MWQI), which means recreational activities can be conducted within the lake area involving body contact. Meanwhile, according to National Lake Water Quality Standard (NLWQS), the water category of Besut Campus Lake can be categorised as Category B, which means recreational activities with secondary body contact. Further in-depth analyses involving other microbiological parameters should be carried out before the water can be recommended for primary contact recreation such as swimming.

In addition, heavy metal analyses were conducted in the laboratory according to American Public Health Association (APHA) methods. Based on the research conducted, Besut Campus Lake was classified as Class Ⅱ with an index value of 78.23 from the Malaysia Water Quality Index (MWQI), which means recreational activities can be conducted within the lake area involving body contact. Meanwhile, according to National Lake Water Quality Standard (NLWQS), the water category of Besut Campus Lake can be categorised as Category B, which means recreational activities with secondary body contact. Further in-depth analyses involving other microbiological parameters should be carried out before the water can be recommended for primary contact recreation such as swimming.","PeriodicalId":14995,"journal":{"name":"Journal Of Agrobiotechnology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79218775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents marine water quality status of river estuarine in Keluang Kecil River Estuary at Bukit Keluang. River estuarine water is classified in Class E in MWQI. In the subsequent MWQI with 0 to 100 scales, marine water quality at 0 will be described as “Poor” and 100 as “Excellent”. This study aims to determine water quality parameters and the water quality status of river estuarine by using Malaysia Marine Water Quality Index (MMWQI). In-situ and ex-situ analyses in this study were conducted for five sampling points that had been selected in the Keluang Kecil river estuary. In-situ parameters, dissolved oxygen (DO), pH, temperature, salinity and ammonia, were measured using YSI Professional Plus Series Multi-parameter during sampling. At the same time, water samples for total suspended solids, phosphate, nitrate and faecal coliform were collected and analysed in the laboratory using a standard procedure based on American Public Health Association (APHA), 2017 and HACH methods and then were compared with the Malaysia Marine Water Quality Standard (MMWQS). The average value of ammonia, nitrate, phosphate and TSS were not within the acceptable limit or standard value set by Department of Environment (DOE) except for dissolved oxygen and faecal coliform. Based on the one-way analysis of variance (ANOVA) result, there are significant differences (P < 0.05) in DO, pH, temperature, salinity, ammonia, TSS and FC in water between stations except for nitrate and phosphate. Marine Water Quality Index (MWQI) was measured for all the sampling stations (S1, S2, S3, S4 and S5) using a formula set by DOE (2019). The mean of MWQI for the Keluang Kecil river estuary measured was 43.45. Thus, the river estuary is classified as Poor (0 – 49). This study can maintain the marine water quality to conserve estuary biodiversity. This study was needed to prevent the possibility of water pollution and water quality can be monitored in that area in the future. The understanding of this study about water quality is to maintain the water quality and facilitate the management as actions can be taken by local authorities and other government agencies to maintain and improve the water quality and create boundaries and regulations that can bring back nature.
本文研究了武吉吉琅的吉二河河口的海水水质状况。江口水在MWQI中被列为E类。在其后以0至100分制进行的海洋水质指数中，海水水质在0时为“差”，在100时为“优”。本研究旨在利用马来西亚海洋水质指数(MMWQI)确定河口的水质参数和水质状况。本研究对在克琅克西尔河河口选定的5个采样点进行了原位和非原位分析。在采样过程中，使用YSI Professional Plus Series Multi-parameter测量了现场参数，溶解氧(DO)、pH、温度、盐度和氨。同时，使用基于美国公共卫生协会(APHA) 2017和HACH方法的标准程序在实验室收集和分析总悬浮固体、磷酸盐、硝酸盐和粪便大肠菌群的水样，然后与马来西亚海洋水质标准(MMWQS)进行比较。除溶解氧和粪便大肠菌群外，氨、硝酸盐、磷酸盐和TSS的平均值均未在环境部规定的可接受限度或标准值范围内。单因素方差分析(ANOVA)结果显示，除硝酸盐和磷酸盐外，各监测站水体中DO、pH、温度、盐度、氨、TSS和FC均存在显著差异(P < 0.05)。采用DOE(2019)设定的公式，对所有采样站(S1、S2、S3、S4和S5)的海洋水质指数(MWQI)进行测量。克琅克孜河河口测得的MWQI平均值为43.45。因此，河口被划分为差(0 - 49)级。该研究可以维持海洋水质，保护河口生物多样性。为了防止该地区出现水污染的可能性，今后可以对该地区的水质进行监测，需要进行这项研究。本研究对水质的理解是维持水质和促进管理，因为地方当局和其他政府机构可以采取行动来维持和改善水质，并建立可以恢复自然的边界和法规。

Heavy metal exhibit toxic and persistent characteristics, can enter into the food chains and the ecosystem where they cause adverse impact on the biotic and abiotic components of ecosystem. Heavy metal pollution in Malaysia has become a major health concern for humans. Thus, this study was conducted to determine the level of cadmium (Cd) and nickel (Ni) in the muscle and gill of fishes collected from the Sungai Kuantan and Sungai Riau. Field sampling was conducted between September and December 2017. Five different species of fishes: Barbonymus gonionotus (Lampam Jawa), B. schwanenfeldii( Lampam Sungai), Hampala macrolepidota(Sebarau), Chitala chitala (Belida), and Hemibagrus nemurus(Baung) were digested by using acid digestion method and analysed with Inductively Coupled Plasma-Mass Spectrometry (ICPMS). Concentration of Cd among species were in order of: H. macrolepidota >B.gonionotus> B. schwanenfeldii> C.chitala> H.nemurus, whereas Ni level in fishes were: C. chitala> H. macrolepidota> B. gonionotus> H. nemurus> B. schwanenfeldii. Among all the species, H. macrolepidota from Sungai Kuantan had the highest Cd in both muscle (0.1761±0.0062¬mg/kg) and gills (0.2938±0.0066mg/kg) whereas the highest Ni level in muscle was noted in C. chitala from Sungai Kuantan with (0.1473±0.0755 mg/kg) and in gills of B.gonionotus (0.4544±0.0470mg/kg) from the same river respectively. It was obtained that there was a significant difference (p<0.05) of Cd in muscle between species. Ni concentration in fishes was below the permissible limit stipulated by World Health Organizations WHO (1985) and Food and Agriculture Organizations (2012) but the concentration of Cd was recorded high. However, it was still below the World Health Organization (WHO) 1985 and Malaysian Food Act (MFA) 1983.
重金属具有毒性和持久性，可以进入食物链和生态系统，对生态系统的生物和非生物成分造成不利影响。马来西亚的重金属污染已成为人类的主要健康问题。因此，本研究旨在测定双溪关丹和双溪廖内河鱼类肌肉和鳃中的镉(Cd)和镍(Ni)含量。实地抽样于2017年9月至12月进行。采用酸消化法对5种不同的鱼类进行了酶解，分别为:Barbonymus gonionotus (Lampam Jawa)、B. schwanenfeldii(Lampam Sungai)、Hampala macrolepidota(Sebarau)、Chitala Chitala (Belida)和Hemibagrus nemurus(Baung)，并用电感耦合等离子体质谱(ICPMS)进行了分析。不同种间Cd浓度顺序为:大鳞翅目田鼠>大鳞翅目田鼠。鱼体中Ni含量为:chitala> H. macrolepidota> B. gonionotus> H.nemurus > B. schwanenfeldii。其中，产自双溪关丹的巨鳞鱼肌肉和鳃的镉含量最高，分别为0.1761±0.0062 mg/kg和0.2938±0.0066mg/kg;产自双溪关丹的赤塔鱼肌肉和鱼鳃的镍含量最高，分别为0.1473±0.0755 mg/kg和0.4544±0.0470mg/kg。结果表明，不同种属间肌肉中Cd含量差异显著(p<0.05)。鱼体内镍的浓度低于世界卫生组织(世卫组织，1985年)和粮食及农业组织(粮食及农业组织，2012年)规定的允许限值，但镉的浓度却很高。但是，仍低于世界卫生组织1985年和马来西亚食品法1983年的规定。
