The phenotypic correlations between different weights were positive and ranging from 0. This is because of the site fertility where the experimentation was carried out. Holstein cows, lactation, Wood, Gamma, season of calving. 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. 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.

Milk, composition, quality, transformation, drying. Wiki Loves Earth in Bulgaria. Summary [ edit ] Description Yakouren 2. In Tunisia, Holstein dairy cattle produced differently according to their calving month. Tree shelters did not have a significant effect on the seedlings survival rate for both oaks, whereas they significantly improved their 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.

A linear model was developed, including herd-test day, farm ownership, calving month, calving year, and lactation number, test year, age of cow and milk test number.

Plantix – Monday, 10 July 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.
