The following 7 pages uses this file: This is because of the site fertility where the experimentation chne carried out. Least squares solutions were used to estimate the performance adjustment coefficients for age of dam and sex-birth mode.

Tree shelters did not have a significant effect on the seedlings survival rate for both oaks, whereas they significantly improved chhene height growth compared to unsheltered seedlings; average growth rate in height inside non-vented and vented tree shelters was each year significantly greater, respectively, by 7. Records of a total of lambs collected over 10 years from to were used in this study.

Ina second inventory was carried out, where we noticed an increase in number of trees and consequently in volume which could be explained by a strong regeneration by sowing in the maquis, the enclaves and after the passage of fires and a lack of application of specific silviculture to these stands, something that we propose in this study that takes into account the social problem and able to ensure the sustainability, the preservation of the forest ecosystem and the production of wood. Summary [ edit ] Description Yakouren 2.

Contrary to height growth, average growth rate in diameter of the sheltered cork oak seedlings was, each year, significantly lower than that of the control by 2 mm for both non-vented and vented tree shelters. In fact, the fat content, protein content and defatted solids content of the different batches of skimmed milk powder were heterogeneous and ranged from 0 to 1.

A total of milk test days of 67 cows in herds during was used in this study. A linear model including the livestock sector state or privatefarm-herd-year of birth-lambing season, maternal age, and sex-mode of birth was used to identify the main sources of variation in the growth of Barbarine. This image was uploaded as part of Wiki Loves Earth Adobe Photoshop Lightroom 5. The REML method was used for estimating heritability.

Views View Edit History. Although the physicochemical characteristics of raw milk, intended for drying, comply with the required standards, they nevertheless remain very variable from one delivery to another, and caused instability in the composition of the produced skimmed milk powder from one batch to another.

Plantix – Monday, 10 July Reforestation efforts, in terms of production of lumber and industrial wood, both in quality and quantity, remain dependent on the application of appropriate silvicultural methods pruning, thinning.

Three organic mulches Italian Stone Pine, Lentisk, a combination of Italian Stone Pine and Lentiskan inorganic mulch gravel and no mulch and two tree shelter types non-vented, vented and control were tested. The density at that time was plants per hectare and plants throughout the serial.

The objectives of this study were to: Maritime pine, pruning, thinning, chehe, silviculture, volume. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. In Tunisia, Holstein dairy cattle produced differently according to their calving month. A linear model was developed, including herd-test day, farm ownership, calving month, calving year, and lactation number, test year, age of cow aeen milk test number.

For zeen oak, average growth rate in diameter inside the vented tree shelters was similar to that of the control, whereas average growth rate in diameter inside the non-vented tree shelters was significantly lower by about 1 mm each year.

The use of mulching alone or in combination with tree shelters seemed to be useless for both oaks. Publication d’un nouveau ouvrage de Mr. Milk, composition, quality, transformation, drying. Copyright This article is published under license to Journal of New Sciences.
