This study examines the strategies and benefits of the taungya farming system to both the government and the rural economy
in Nigeria. An interview survey was conducted in which data were collected from 115 randomly selected farmers in five villages
in the Oluwa forest reserve, Ondo State, Nigeria. The study examines the extent of participation of rural dwellers in plantation
development through taungya farming and the degree of success of this system as an afforestation method. The farmers were
predominantly illiterate, within the age bracket of 35–54 years and with small farm holdings. Twenty nine percent relied totally
on food from the forest reserve for their livelihood, while 71% also had farm holdings in free areas. Land within the reserve
is allocated to farmers free of charge but compensation is paid to landlords on land from free areas. A statistically significant
difference was detected in income from the two sources of farmland for the households and but not in the size of land allocated
under taungya and free areas. About 184 farmers are involved in taungya annually, and 410 ha of Tectonia grandis has been established for the government of Ondo State. 相似文献

Exotic species possess abilities to harm the ecosystems they invade. This study assesses the density, frequency and cover of exotic plants in roadside right-of-ways, logged areas and wildfire sites within mixedwood sections of the southern boreal forest of Saskatchewan. A total of 23 exotic species were observed including nine species of Gramineae, seven species of Leguminosae and five species of Compositae. Average density of exotic species in areas recently disturbed by timber harvesting or wildfire was 0.2 stems m−2 with a frequency of 72%. Exotic species adapted for wind dispersal were best represented including common dandelion (Taraxacum officinale), perennial sow thistle (Sonchus arvensis) and annual hawksbeard (Crepis tectorum). Only two exotic species, T. officinale and Canada bluegrass (Poa compressa), were observed in mature forest; both occurred with a frequency of 13% and an average density of 0.002 stems m−2. A total of 22 exotic species was found in the right-of-ways quadrats with an average density of 117 stems m−2 and a frequency of 94%. The most frequently observed exotic species in the roadside right-of-way areas were T. officinale, alsike clover (Trifolium hybridum), S. arvensis, creeping red fescue (Festuca rubra) and smooth brome grass (Bromus inermis). These species are either common agricultural weeds or were part of the original seed mixture used to establish a plant cover in the roadside right-of-ways. 相似文献

The objective of the current study was to evaluate the effects of feeding increasing levels of velvet bean seed meal (VBM; 0, 12, 24, and 36 %) on the performance of Mashona doelings. Dry matter intake was lower (P?<?0.05) for the control diet compared to VBM diets, but linearly declined (P?<?0.05) with increasing levels of VBM. Average daily weight gain was significantly different between experimental groups. Doelings’ final live weights and average daily gains were slightly higher in control group than other three supplemented groups where they linearly declined (P?<?0.05) with increasing levels of VBM. The cost per kilogram of feed, however, decreased with high inclusion level of VBM. Result suggested that high inclusion level of VBM negatively influenced the growth of young goats probably due to the presence of some anti-nutritional factors which needs further investigation. 相似文献

The objective of the study was to determine growth performance, viscera organ development, economic benefit and sensory characteristics of meat from broilers finished on Acacia anguistissima leaf meal-based diets. One hundred and eighty Cobb 500-day-old chicks were used in the study. Acacia anguistissima was used as a protein source and included in broiler diets at 0, 50 and 100 g/kg. Total feed intake (TFI), average daily gain (ADG), and gain to feed ratio (G:F) and cost benefit analysis were determined. There were no differences in TFI of broilers across treatments diets. Average daily gain and gain to feed (G:F) ratio were low (P?<?0.05) for broilers feeding on diet with100 g/kg acacia meal. Highest returns from weight gain were obtained from broiler chickens fed on diet with 50 g/kg inclusion level of A. anguistissima (P?<?0.05). Intestinal length increased with inclusion level of A. anguistissima whereas liver and spleen weight decreased with inclusion level of A. anguistissima (P?<?0.05). Female consumers gave higher scores for overall flavour intensity than male consumers (P?<?0.05). Treatment diets influenced consumer sensory characteristics of broiler meat (P?<?0.05). High sensory scores were observed for overall flavour intensity (OFI) for both boiled and deep fried meat from broilers fed 100 g/kg A. anguistissima. It can be concluded that A. anguistissima meal can be used effectively up to 50 g/kg in broiler diets without compromising performance of chickens and can influence a few sensory characteristics. 相似文献

This review aims to highlight the effects of ochratoxin A (OTA) in the feed of meat-producing animals. The accumulation of OTA in feed and its distribution in various farm animals were compared and evaluated. Primarily, the oral administration of OTA-contaminated feed and the predisposition in an animal''s vital organ were critically examined in this work. The collated reports show that OTA directly associated with endemic nephropathy and its high concentration leads to degeneration of liver cells, and necrosis of intestinal and lymphoid tissues. At present, limited reports are available in the recent literature on the problems and consequences of OTA in feed. Therefore, this review focused on the OTA carryover from feed to farm animals and the interaction of its secondary metabolites on their biochemical parameters. Hence, this report provides greater insights into animal health related to OTA residues in meat and meat products. This article also explores mitigation strategies that can be used to prevent the carryover effects of OTA in livestock feeds and the effects in the food chain. 相似文献

The moss bag technique of air quality monitoring has been used to assess the spatial distribution of metal particulates blown as dust from U tailings adjacent to the Lorado mill in northern Saskatchewan. Monitoring sites were set up at 32 locations on and around the tailings during June, July, and August, 1982. Of the 23 metals initially detected in the tailings by plasma emission spectroscopy, 8 were found to be deposited on the moss bags at concentrations in excess of 0.01 μg cm?2 day?1. Particulate concentrations were generally highest in the central and eastern parts of the tailings dropping off rapidly in the surrounding area. Although this could in part be due to climatic conditions, it is probably the sandy texture of the tailings which restricts the distribution of particulates in this region. 相似文献

The effects of chemical modification on the thermal stability of cultivated Acacia
mangium and Acacia
hybrid wood species were investigated. Evidence of modification was indicated by increase of weight and was confirmed by Fourier
transform infrared analysis (FT-IR). The thermal stability measured by thermogravimetric analysis (TGA) increased after esterification
with propionic and succinic anhydrides. Thermal stability of succinylated samples was found to be highest based on the values
of on-set degradation temperatures, the temperatures at which 30, 50, and 70% degradation occurred. The observed higher thermal
stability of the succinylated and propionylated Acacia wood samples when compared with unmodified wood was attributed to the reduction in hydrophilic nature of the wood due to
esterification reaction. 相似文献
