Abstract

The eruption of Merapi from October 26th to November 6th, 2010 has affected social life and environment around the Merapi. The eruption has caused destruction of land and water resources, plants, death of animals and human casualities. The lava, dust and stones released from the eruption of Merapi had caused residential destruction, casualities, agricultural land and plants destruction, and contamination of water. The eruption has directly affected 4 districts including Sleman (Yogyakarta), Magelang, Boyolali and Klaten (Central Java) categorized as Disaster Risk Area (DRA). The purpose of this assessment is to analyse the impacts of Merapi eruption in animal health and productivity in particular for dairy and beef cattle. A total of 2.828 heads of cattle was reported died during the eruption of Merapi, and 1.962 heads died at the time of eruption and 36 heads at the arrival on evacuation areas. Animal that found died including 423 heads of beef cattle (0.13%) and 2.405 heads of dairy cattle (3.2%). Clinical sains noted after the eruption were reduction of milk production, loss of appetite, diarrhoea, respiratory disturbances, mastitis and collapse. The main problems for livestock were reduction of milk production, collapse of dairy milk corporation activities and contamination of water resources. Other than dairy cattle mortality, the reduction of milk production may be caused by subclinical mastitis and environmental distress due to temperature and noise of eruption for few days. The subclinical mastitis should be further investigated to establish rehabilitation programme for dairy milk agribussiness activity in particular around the DRA of Merapi.

Abstract

Vegetables and dairy milk are important commodities in Pangalenganand Lembang, West Java. However, agrochemicals areused intensively and excessively in production system. Therefore,pesticide residues and contamination commonly occurredin agricultural products and environments. The study aimed toassess farmers’ attitudes on pesticide toxicity and reducingpesticide residues in animal and food crops products, andinvestigate the attitude changes of farmers on pesticide use. Itwas an on-farm research and farmers were directly involved inthe study. The attitude change was analyzed on questionnaireand interview base for over 99 respondents in Pangalengan andLembang between 2001 and 2003. Samples of soils, weeds,cabbages and milk were collected for pesticide residue analysis.Results showed that farmers did not aware on toxicity effectsof pesticides in both animal and human health. There wasmisinterpretation among the farmers where pesticides wereregarded as drugs rather than toxic compound to increaseproductivity. The organochlorines/OCs (lindane and heptachlor)were common pesticide contaminants found in soils of 7.9-11.4 ppb, but no organophospates (OPs) were detected. BothOCs and OPs were also detected in soils of Lembang at a rangeof 11.53-65.63 ppb and 0.6-2.6 ppb, respectively. There werepesticide residues detected in weeds collected from Pangalengan(8.93 ppb lindane, 2.05 ppb heptachlor, and 33.27 ppbchlorpyriphos methyl/CPM and Lembang (6.45 ppb lindane,2.65 ppb endosulfan, 6.85 ppb diazinon, and 0.5 ppb CPM).Only endosulfan with least residue level (0.1 ppb) was detectedin organic cabbages, whereas lindane was detected much higher(3.7 ppb) in non-organic cabbages. Pesticide residues were notdetected in milk of dairy cattle fed on by-products of organiccabbages, but lindane was still present in milk of dairy cattle fedon non-organic cabbages for 7 days subsequently. The presentstudy indicates that the organic farming practice may reducepesticide residues in animal and agricultural products. Farmersappreciated that pesticides may cause residual effects on theirproducts (95.2%) and affected public health and environment(92.9%). Therefore, they were willing to convert theiragricultural practices to organic farming (69.1%).

Abstract

The purpose of this study was to investigate pathological and biochemical changes in intoxication of mindi leaf (Melia azedarach) on skeletal muscle and myocardial tissues . Fifty two male Wistar rats weighing 140 g to 240 g were intoxicated in 20%; 25% and 40% diet of mindi leaf ad libitwn for 25 days . Clinical signs did not appear the intoxication of mindi leaf. Specific pathological changes were not found macroscopically except cachexia and paleness . Skeletal muscle lesions on the other hand, were consistently noted microscopically . There were degeneration, necrosis and fragmentation of muscle fibres ; enlargement of nuclei ; fibrosis; oedema and hyalination . The hyalination was prominent and appeared to be more. progressive two weeks after dosing . Following the skeletal muscle lesions, myocardial showed degeneration, necrosis and fragmentation of fibres ; enlargement of nuclei and hypercellularity . Regeneration of skeletal muscle developed on day-5 after the substitution of mindi diet by normal diet indicated by disappearing of hyalin tissues . But, myocardial appeared to be regenerated two days after the substitution of diet . Enzymatic activities of alanine aminotransferase (ALAI) and aspartate aminotransferase (ASAT) were not affected. Both enzymes in treated animals were lower than the control . The substitution of diet showed an increased of enzymatic activities during the first two weeks of feeding then reduced at the subsequent weeks . However, these enzymes increased on day-3 after substitution and appeared to maximum followed by a reduction of enzymatic activities in week-4 . On the other hand, creatinine phosphokinase (CPK) was affected in which higher level was noted in treated groups than control . Substitution of diet has led to the reduction of cpc level on day-2 and appeared to reach the same level as in control group on day-21 . The control group was not affected either clinically, pathologically or biochemically . It remained normal throughout the experimental period .

Abstract

Aflatoxicosis is a disease generated as the consequence of aflatoxin contamination in foods and feeds. Garlic (Allium sativum Linn.), a natural spice known to reduce the toxicity of aflatoxins in poultry. Twenty five laying hens were used to study the effectiveness of garlic extract in reducing aflatoxicosis. The animals were divided into 5 groups i.e (1) control group, (2) group treated with 0.4 mg/kg BH, (3) group treated with 0.4 mg/kg BH and 4% garlic extract in feed, (4) group treated with 5 mg/kg BH, and (5) group treated with 5.0 mg/kg BH and 4% garlic extract in feed. Body weight gains, eggs production, and the activity of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), and γ-glutamytransferase (γ- GT) enzymes were observed every week. The residue levels of the aflatoxin and metabolites were measured in the eggs using high performance liquid chromatography (HPLC). The results indicated that group treated with 0.4 mg AFB1/kg BH dan 5.0 mg AFB1/kg BH resulted in decreasing body weight gains, egg production, and increasing the level of GOT, GPT and γ-GT. The addition of 4% garlic extract in the feed was effective to improve the body weight gain and egg production only in the group of chicken treated with 0.4 mg AFB1/kg BH. However, it decreased the enzymes activities of the GOT, GPT, and γ-GT, as well as reduced the aflatoxin residues and metabolites in the groups at both aflatoxin levels (0.4 and 5.0 mg/kg BH). Aflatoxin residues decreased up to 42.2% for the group treated with the low dose of AFB1 (0.4 mg/kg) and 49.0% for the group treated with the high dose of AFB1 (5 mg/kg).   Key words: Garlic, aflatoxicosis, laying hens, aflatoxin residues

Abstract

Pesticides as agrochemicals are used to control plant diseases, however the use of pesticides may cause poisoning for human health and non-target animals, residual formation in animals and crops, and environmental contamination (soils and water). The impacts of pesticide are generally due to excessively or inappropriate use of pesticides. The surveillance on pesticide residues and/or contamination in animal products, crops and environment conducted in West Java and Lampung shows that some pesticide residues were detected in milk from West Java (Bogor and Pangalengan) including lindane, heptachlor, diazinon and endosulfan. In general, the pesticide residues in milk ofBogor were below the maximum residue limits (MRL), but two pesticide residues in milk of Pangalengan: diazinon (239 ppb) and heptachlor (60,3 ppb) appeared to be sufficiently high for human consumption. Some pesticide residues were also detected in meat, liver and fat of cattle in Bogor and Lampung. Both organochlorine and organophosphate residues were detected in samples of Bogor including: lindane (not detected/nd-135,5 ppb) and diazinon (nd-754,4 ppb) in meat; lindane (nd-16,7 ppb), diazinon (nd-969 ppb) and endosulfan (nd-191,8 ppb) in liver; and diazinon (nd-908,1 ppb) in fat. The residue level of diazinon detected in meat, liver and fat appeared to be higher than the MRL level. On the other hand, there was only organochlorine being detected in meat of Lampung. Regarding to pesticide residues being detected in soils, the source of contamination was then suspected from the contaminated soils where fodders being grown (grass, cabbages and corn). By-products of cabbage and corn are commonly used as animal feed for dairy and beef cattle respectively. The organic fanning system can be used as an alternative to minimise agricultural land contamination and pesticide residues in agricultural products. The low pesticide residues in agricultural by-products were able to reduce pesticide residues in animal products (meat and milk). The possibility of pesticide contamination should be taken into account in using agricultural by-products for animal feed to prevent pesticide residual effects in animal products.

Abstract

An integrated farming system between rice and beef cattle was initiated in 2000 in Sukamandi, West Java. However, since 2002 some cattle were suffering from neurological and ophthamological signs, and some of them were found dead after consuming rice straws. Field studies showed that 6 out of 12 cattle were suffered from eye disorders such as blindness, corneal opacity and sereous lacrimation. Two of 6 cattle were severely affected. But, neurological signs were not found during field observation. Pesticide analysis in rice straws shows that both groups of pesticide, organochlorines (OP) and organophosphates (OP) were detected. Residues of OC were higher than OP as shown as 14.41 vs 2.84 ppm (before processing) for OC and 1.80 vs 0.0003 ppm (processed) for OP consisting aldrin, lindane, dieldrin, endosulfan and chlorpyrifos methyl. There was only OC detected in sera consisting lindane (0.6–37.6 ppb); heptachlor (0.03–4.4 ppb); and aldrin (0.8–20.4 ppb) with an average total of 21,4 ppb. The neurological and ophthalmological signs were suspected to be due to organophosphates (OPs) contaminated-rice straws and any other factors such as insufficient vitamin A, magnesium and calcium. Feed replacement with fresh grasses for two cattle reduced corneal changes. Similar symptoms were also reproduced in Wistar rats dosed intraperitoneally with chlorpyriphos methyl. Clinical signs included incoordination, cachexia, eye disorder and corneal opacity. Necropsy showed hepatic injury (hepatic necrosis, mottling of hepatic surface and pale); pale kidneys; swollen of spleen and hyperaemic brain. Microscopic changes were found in brain, liver and eyes. Hepatic changes included haemorrhages, centrolobular hepatic necrosis and focal coagulative necrosis. Brains were showing focal necrosis, haemorrhages, vacuolisation, neuronal necrosis, chromatolysis and nucleolysis. Eyes appeared to have necrosis of tunica muscularis, haemorrhages and eosinophilic infiltration. The study indicates that organophosphates contamination in rice straws as animal feed may lead chronic neurological and ophthalmological symptoms.     Key Words: Contamination, Pathology, Organophosphates, Rice Straws, Cattle

Abstract

Five extracts were obtained from Ageratum conyzoides leaf extracted in methanol-water (4 :1). They were neutral extract (in ethyl acetate), moderately polar extract (in chloroform); basic extract (in chloroform-methanol), polar extract (in methanol), and filtrate. Three extracts were tested biologically and the moderately polar extract was found to be most toxic for female Wistar rats . While the toxicity of neutral extract was mild and other extracts were non-toxic. Therefore, the moderately polar extract was investigated for the hepatoxicity effects in the present study. Intragastric dosing of this extract in rats has caused mortality with clinical signs of weakness, low activity and death. Pathological examination showed mottling on the capsular surface of liver. Microscopically showed anisokaryosis, megalocytosis, bile duct cells proliferation and necrosis . Multiple dosing of this extract may lead to liver and lung injury showing anisokaryosis, megalocytosis, bile duct cells proliferation, centrolobular necrosis, vacuolisation, mitotic figures and mononuclear cells infiltration in the liver and epithelialisation of alveolar walls, thickening of alveolar walls and oedema in the lungs. Liver regeneration occurred 7 days after the last dosing showing mitotic figures and return to the normal structure of liver. The average body weight gain reduced during the first 3 weeks of intoxication from 127.6 g. on predosing to 120,4 g. on week-3 followed by an increased on body weight until the last experiment to 130.8 g. when dosing of extract was terminated . There was an increased of alanine amino transferase ( ALAT) during the first 2 days after dosing from 14.6 IU/1 to 23 .0 IU/1 and reduced at the following days to 7.5 IU/1 at day-5 after dosing . Dosing with retrorsin has caused an increased in ALAT consistently during the first 5 days to 8.7 IU/1 . The activity of aspartate amino transferase (ASAT) reduced during the first 3 days after dosing with the extract from 29 .2 IU/1 to 15 .1 IU/I and from 15 .9 IU/1 to 8.9 IU/1 with retrorsin, but both enzymes appeared higher than control rats . The analysis of toxic  compound in A. conyzoides leaf showed that the Rf value was similar to retrrorsin showing the leaf containing pyrrolizidine alkaloid compounds.   Keywords: Ageratum conyzoides, retrorsine, pathology, regeneration, liver, lungs
