EFFECT OF FEEDING EXTRUDED HATCHERY WASTE ON THE PERFORMANCE OF SOVIET CHINCHILLA RABBITS

[EN] Seventy five, Soviet Chinchilla 6 week-old rabbits just weaned were divided into 5 treatments, H1 , H2, H3, H4 and H5. Each group was further divided into 5 replications of 3 rabbits raised in the same cages and fed with extruded hatchery waste mixed with soja meal (40:60) at O, 1.5, 3.0, 4.5 or 6% level replacing fish meal from rabbits diet at O, 25, 50, 75 or 100% level. The body wt. gains were 978, 998, 1030, 899 and 908 g in H1, H2, H3, H4 and H5 treatments, respectively indicating no statistical difference. The FCH and PEH values were 3 .79, 3.64, 3.53, 3.71 and 3.46 and 1.641, 1.712,1.764,1.674 and 1.798 in H1, H2, H3, H4 and H5 treatments, respectively. There was no statistical difference in the carcass traits between the treatments. The cost of producing 1 kg live wt. gain was lowest (Hs, 14.39) in H5 and highest in H1 (Hs.16.47) indicating the EHWM incorporation in rabbits diet totally replacing the fish meal is most economical.[FR] Soixante quinze lapins "Soviet Chinchilla", juste sevrés, agés de 6 semaines ont été répartis en 5 lots, H1, H2, H3, H4 et H5, Chaque groupe a été ensuite divisé en 5 blocs de 3 lapins élevés dans la meme cage et nourris avec l'un des 5 aliments contenant O - 1,5 - 3,0 - 4,5 ou 6% d'un mélange de déchets de couvoir et de tourteau de soja dans la proportion 40:60 puis extrudé (EHVM). Ce mélange était introduit en remplacement de la farine de poisson de l'aliment témoin a raison de de O, 25, 50, 75 et 100%. En 6 semaines, le gain de poids vif a été de 978, 998, 1030, 899 et 908g pour les régimes H1 a H5 respectivement, sans différence significative. L'indice de consommation a été de 3,79 - 3,64 - 3,53 - 3,71 et 3,46 et le gain de poids par g de proteines ingérée de 1,641 - 1,712 - 1,764 - 1,674 et 1,798 pour H1 a H5 respectivement. 11 n'y a pas de différence statistique entre les caractéristiques de carcasses des différents traitements. Le coüt de production pour 1 kg de gain de poids vif est le plus bas (14,39 Houpies) pour le lot H5 et le plus élevé pour H1 (16,47 Houpies) montrant que l'incorporation d'EHWM dans l'aliment en remplacement total de la farine de poisson est économique.Handa, M.; Sapra, K.; Shingari, B.

Chemical characterization of wet precipitation events and deposition of pollutants in coal mining region, India

The present study investigated the chemical composition of wet atmospheric precipitation in India’s richest coal mining belt. Total 418 samples were collected on event basis at six sites from July to October in 2003 and May to October in 2004 and analysed for pH, EC, F−, Cl−, SO2_ 4 , NO_3 , Ca2+, Mg2+, Na+, K+ and NHþ4 . The average pH value (5.7) of the rainwater of the investigated area is alkaline in nature. However, the temporal pH variation showed the alkaline nature during the early phase of monsoonal rainfall but it trends towards acidic during the late and high rainfall periods. The rainwater chemistry of the region showed high contribution of Ca2+ (47%) and NHþ4 (21%) in cations and SO24_ (55%) and Cl− (23%) in anionic abundance. The high non seas salt fraction (nss) of Ca2+ (99%) and Mg2+ (96%) suggests crustal source of the ions, while the high nss SO24_ (96%) and high SO2_ 4 _ NO_3 _ þ C1__ratio signifying the impact of anthropogenic sources and the source of the acidity. The ratio of SO2_ 4 þ NO_3 _ NHþ4 _ þ Ca2þ_varies from 0.03 to 3.23 with the average value of 0.84 suggesting that Ca2+ and NHþ4 play a major role in neutralization processes. The assessment of the wet ionic deposition rates shows no any specific trend, however Ca2+ deposition rate was highest followed by SO2_ 4 and NH4
