满山红茶，遍地宝石香料引起的地理大发现

在古老的僧伽罗语中,“斯里兰卡”是“光明富饶的土地”之意,这里一年四季气候温暖,雨量充沛,特别适合各种植物生长。在斯里兰卡岛上,生长着数不清的奇花异草,很多都是宝贵的资源,比如那曾引发世界地理剧变的特殊植物--香料植物。     

千年佛国诞生记漂洋过海的菩提树，郑和舰队的补给处

斯里兰卡人的祖先是僧伽罗人,关于这个民族的起源,在斯里兰卡流传着诸多说法,且很多都带有浓厚的神话色彩,比如据斯里兰卡本国典籍记载,古印度僧诃劫波城有一位名叫“僧伽罗”的商人,他带领500名随从来到斯里兰卡,路上被女妖迷惑,最后在神的指点下消灭女妖,当地民众便推举僧伽罗登基为王,他的后代便自称“僧伽罗人”。这个传说在玄奘法师的《大唐西域记》中也有记载,除少数情节有所出入,其余均大致相同。     

Rotavirus-associated diarrhoea in buffalo calves in Sri Lanka

Faecal samples from 150 buffalo calves, one to 150 days old, located in various districts of Sri Lanka, were examined for group A rotavirus antigen by a screening enzyme linked immunosorbent assay (ELISA). Positive samples were confirmed by the blocking ELISA. In the calves studied 27·3 per cent were diarrhoeic, and the rest were non-diarrhoeic but were in contact with the animals showing diarrhoea. Antigen was detected in 36·6 per cent of the diarrhoeic animals and in 11·9 per cent of the nondiarrhoeic animals. There was a strong association between the presence of antigen in faeces and diarrhoea in these animals (ξ² = 46·98; P<0·001). Of the 146 serum samples examined for antirotaviral antibodies, by the blocking ELISA at a single serum dilution (1:20) against a constant dose of antigen (8 units), 68·5 per cent were positive indicating a widespread infection with the virus in the population studied. This is the first record of the detection of rotavirus and its association with diarrhoea in buffalo calves in Sri Lanka.     

Cetacean occurrence and diversity in whale-watching waters off Mirissa,Southern Sri Lanka

Scientific information is vital to the conservation of cetaceans and the management of whale-watching activities. The southern coastal waters of Sri Lanka are near a narrow continental shelf and biologically abundant in cetacean species. Although the occurrence of cetaceans has been investigated in certain waters of Sri Lanka, few surveys have been conducted along the southern coast. To fill this gap, we conducted boat-based surveys from January to May 2017 to investigate the occurrence, diversity, and behavior of cetaceans in the waters off Mirissa, covering a survey area of 788.9 km². During 55 survey days, we recorded a total of 242 cetacean sightings and identified at least 9 species (3 mysticetes and 6 odontocetes). The blue whale was the most common mysticete species (167 of 174 mysticete encounters), followed by the Omura's whale (4 of 174) and Bryde's whale (3 of 174). The spinner dolphin was the most common odontocete species (28 of 68 odontocete encounters), followed by the sperm whale (18 of 68), common bottlenose dolphin (13 of 68), short-finned pilot whale (5 of 68), melon-headed whale (2 of 68), and killer whale. Blue whales and sperm whales exhibited a clear preference for outer shelf and high slope areas, and blue whales were observed feeding along these waters. The present study provides near-baseline information on cetacean occurrence and diversity in whale-watching waters off southern Sri Lanka, and highlights the urgent need for proper management strategies for whale-watching activities.     

Incidence of brucellosis in Sri Lanka: an overview

Infection by Brucella abortus seems to be a major cause of abortions among cattle and buffaloes in Sri Lanka. The incidence of this disease is more prominent among the animals in the Dry zone of the country raised under extensive management systems. The present low incidence of this disease and the small size of the country may facilitate launching of an effective disease control scheme. The milk ring test (MRT) has proven to be usable in testing milk for the infection at farm level. An ELISA technique could be employed to test the seroprevalence of infection among MRT-positive animals. A program to purchase the diseased animals by the state for slaughter, and a countrywide vaccination program with B. abortus strain RB51 would enable the country’s livestock industry to eventually eradicate this disease.     

Risk,prognosis and causality of parvo viral enteritis in dogs in Sri Lanka

We studied the causal variation, prognosis and risk factors of parvo viral enteritis using both molecular and statistical analysis. A multivariate factor analysis was performed to see the effect of the breed, age, vaccination status and the leukocyte counts on disease severity and survival. Twenty PCR amplicons (partial VP2 gene) from vaccinated dogs were sequenced to identify the variants. A total of 109 samples were positive for parvo viral DNA, 71 of which were from dogs who have received at least one dose of CPV-2 vaccine. Over 90% were leukopenic on 2^nd and 3^rd day of diarrhoea. Age < 6 months was negatively correlated with leukocyte count and the leukocyte count was negatively correlated with survival. Dobermans and Labradors showed significant negative correlation with survival. All variants of parvovirus affected dogs with the 2c being the predominant (2c = 12, 2a = 7, 2b = 1). All 20 strains harboured three additional amino acid substitutions (i.e. Phe267Tyr, Ser297Ala and Tyr324Ile) and warrant further studies on potential changes of the antigenicity of the virus.

Feeding of Dairy Cattle in the Forest-Garden Farms of Kandy,Sri Lanka

A survey on feeding practices was conducted with 60 farmers belonging to four categories (15 farmers in each): male farmers without off-farm income (M^–), male farmers with off-farm income (M⁺), female farmers without off-farm income (W^–), and female farmers with off-farm income (W⁺). Data on herd size, feeds offered, milk production, chest girth, reproduction and management were collected monthly over a period of 1 year. In addition, samples of fodder and concentrates were collected monthly and analysed for dry matter (DM), organic matter (OM), crude protein (CP) and in vitro organic matter digestibility (OMD). Of the 550 rations analysed, grass was included in 99.8% of all rations, followed by gliricidia (65%), creepers (50%) and jak leaves (32%). Consequently, the rations were high in OMD (47–59%) and CP (7.8–23.5%). High-protein forage or coconut cake or both were also included as a supplement in 92% of the rations. Both M^– and W^– farmers had larger (p<0.001) herds (mean 1.8 animal units (AU) per household) than their counterparts with off-farm income (mean 1.44 AU/household), but only the male farmers without off-farm income achieved higher feeding levels (84.4 vs 65.6–72.1 g digestible organic matter (DOM)/kg^0.75 per day) and milk production (6.4 vs 5.3–5.7 L/lactating cow). The lower production of animals kept by female and M⁺ farmers was related to lower feeding levels. M^– farmers realized higher feeding levels than their M⁺ counterparts. W^– farmers did not collect extra feed in response to higher levels of production. It was concluded that dairy farming in the mid-country of Sri Lanka is particularly important for poorer households without income from off-farm employment.
