An N-free diet was supplemented with limited but increasing amounts of proteins (30, 60, 90 g/kg diet from a mixture of casein and egg yolk), in order to measure their effect on the ileal endogenous amino acid (AA) losses in pigs. The study was conducted at 2 dietary fibre levels: 20 and 80 g/kg, isolated from pea seeds. Compared to the N-free diet, a supply of 30 g proteins was sufficient to obtain a positive N retention and the following supplies allowed a constant and linear increase (0.88 g N retained/g N intake). The same supply induced an increase in ileal endogenous losses, compared to the control (10.7 vs 7.2 g AA/kg DMi for the low fibre diet) but the difference was not significant because of a high variability between the pigs. The supplies of 60 and 90 g proteins did not modify the level of the losses either: 10.2 and 10.6 g AA/kg DMi, respectively. The same trends were observed for the diets with a high fibre level but, in this case, the losses were significantly higher: respectively 14.9, 16.7, 15.7 and 17 g AA/kg DMi. On the other hand, the fraction of the digesta containing the free AA and the small peptides (< 3 kDa), supposed to be mainly of dietary origin, remained independent of the protein level. This suggests a virtually complete digestibility of the dietary proteins. Thus, pea fibres induce a significant increase of the ileal endogenous losses but without disturbing the protein digestion process, as suggested by the N retention. The protein supply probably increased the digestive secretions but the latter could have been highly reabsorbed, due to a lack in dietary factors susceptible to increase the reabsorption. [less ▲]

Two groups (A and B) of 6 piglets, weaned at 21 days (D0), received ad libitum the same diet during three weeks. The piglets of group A were not submitted to a colostrum supplementation while those of the group B received daily and orally 5 g of bovine colostrum. Each week, piglets were weighed and blood was taken on each one of them. One piglet of each group was sacrified on D0 and the rest of the animals on D21. Mesenteric lymph nodes (ML), iléal Peyer patches (iPP), jejunum and spleen biopsies were taken on each piglet before death. The haematological values and the intestinal histo-morphological data between the two groups were not significantly different, but FACS analyses on the lymphocytes in the biopsies and the determination of stimulation index suggested a significative effect of colostrum on the lymphocytes populations, with, in the ML, an increase of the LB population (14 % vs 28 %, P < 0,05) and, in the iPP, a reduction of the LB's (54,99 % vs 8,44 %, P < 0,01) with an increase of the LT cells (16,87 % vs 72,00 %, P < 0,001). An increase of the lymphocyte stimulation index from piglets receiving colostrum was observed the second day of in vitro stimulation with colostrum. In brief, the answer of the immunity system to bovine colostrum seems to be restricted to the intestinal immunity system and is characterised by an activation, a multiplication and a modification of the lymphocytes ratios.

Effect of forest canopy on the accuracy of a differential global positioning system (dGPS). The possibilities to use dGPS for forest mapping are analysed. The efficiency of dGPS in forest condition is linked to canopy interference, which intercepts signals sent by some of the satellites or reflect them (multipathing). Two types of equipment have been tested : a TrimbleTM Svee Six coupled with a RDS differential receiver and a Trimble SK8 coupled with an OMNISTAR differential receiver. Recordings have been achieved according to two modes : static (recording on one spot during one minute) and cinematic (moving continuously along the stand limits). Two types of forest canopy were compared : light canopy made of young poplar plantation with few obstacles in the vicinity, and closed canopy of mature spruce stand edged with other mature stand. Cinematic mode efficiency is higher than static one (mean errors are respectively 3.1 m and 9.1 m). In the same way positioning is more accurate for the stand with light canopy than for the other one (mean errors are respectively 2.9 m and 9.4 m). Difference between recording modes are probably due to multipathing effect that filtering algorithm integrated in the GPS receivers are not able to remove in static mode. The efficiency of differential signal reception is also different for the two stands : 1.3 % and 20.5 % of missing differential signal respectively in the light and dense canopy conditions. [less ▲]

Jatropha curcas oil has an insecticidal activity harnessed by the farmers in Niger. In this study, we compared the insecticidal activity of two batches of oil conserved during 70 days, one exposed to light and the other kept in the dark. The insecticidal efficacy was evaluated in a field with three concentrations (5, 10 and 15%) trial on the main pests of Cowpea (Vigna unguiculata (L.) Walp) and in a laboratory test on Megalurothrips sjostedti Trybon (Thysanoptera: Thripidae) with different concentrations of crude oil (50; 100; 150 and 200 µl). No difference in insecticidal effect was found between the two modes of oil conservation, both in the laboratory and in the field. In the field, regardless of the mode of conservation, the concentrations of 10% of J. curcas oil enables a reduction of over than 80% of thrips, aphids, and bugs compared to the control. Its increased seeds yield more than 50%. The concentration of 15% gives an insecticidal effect comparable to that of the reference treatment (deltaméthrine) but induces phytotoxicity symptoms on the leaves of Cowpea. [less ▲]

Public Market Information System (PMIS) is implemented in Benin to collect food prices and their flows which are largely disseminated mainly through national or community radio stations in all regions. This intervention is expected to deliver significant positive impacts on food producers. However, little empirical and systematic analysis has been carried out to evaluate them, particularly the effects on farm gate prices. This article analyses how the reception of improved agricultural market information affects the maize farm gate prices. A distinction has made between access to market information and use of market information. A closer follow-up over each maize transaction during one year was implemented among a stratified sample of 124 maize surplus producers. We find evidence suggesting that better-informed farmers by PMIS managed to bargain for higher prices irrespectively to the transaction modes (selling under contract, selling on distant market, selling at the farm gate without contract). The average price difference per kilogram of maize sold between households with and without PMIS (also referred to as an SPIM premium or PMIS rent) is 23%. The data showed that a farmer who sells under contract with an itinerant trader (contract accompanied by an offer of credit) received the lower prices but they received a higher price when they have access to and use PMIS data. The study confirmed that PMIS is a useful intervention which together with improved access to credit will allow smallholders to better exploit market opportunities. [less ▲]
