Introduction
Goats are considered among the productive agricultural animals, which are suitable for breeding in Syria, as the average number of heads of milking goats, the total number of goats, and milk production amounted to about 1330851 heads, 1995 208/ Despite the suitability of the climatic conditions and the nature of the Syrian lands for this type of activity, the great pressure on pastures, the unavailability of fodder materials and the high prices of them necessitate the search for non-traditional alternatives in nutrition, and natural products to combat diseases, among which were probiotic growth stimuli Basavaraju et al. [1]. Probiotics are live bacteria and yeasts beneficial to health, especially for the digestive system in which they are originally present Faujdar et al. [2]. Putting the biological promoter in feed mixtures to different animals as nutritional additives shows a positive effect on the gastrointestinal tract, and inhibition of other pathological microorganisms Anuradha et al. [3]. Probiotics are used to improve productivity indicators by improving the digestive process by affecting the balance of rumen flora, and they help demonstrate the genetic potential of the animal feeding on it Ghorbani et al. [4].
Probiotics increase the production of volatile fatty acids, short and medium chain fatty acids, and thus an increase in the energy available to the agricultural animal Rombeau et al. [5]. It has been found that adding microbial nutrition (probiotics) increases body   [6].Lema et al. [7]. There was no effect of adding probiotics on red and white blood cell counts and protein in the blood of agricultural animals Sadieket al. [8]. Sayed [9] found an increase in hemoglobin and protein concentrations, and both leukocyte counts and AST (aminotransferase steroids) were not affected in the goats.
WhileAntonovic et al. [10] observed a decrease in the concentration of glucose, urea, ALT, and AST (aminotransferase aspartate) in lambs, and an increase in both bilirubin and triglycerides. The study Al-Rubeii et al. [11], included adding different percentages of probiotics (0.2%, 0.4%, 0.6%) to the diet of Awassi lambs, with the aim of finding out the extent of their effect on some quantitative and qualitative characteristics of meat. The results of the experiment showed the superiority of all biological reinforced treatments over the control treatment, related to carcass characteristics, physical composition, muscle and bone distribution and fat distribution pattern, and the treatment was 0.4% higher than the rest of the treatments in all measurements.

Research Goal
The research aims to find out the effect of growth stimuli/ probiotics/on the diets of dairy mountain goat females on productivity indicators.

Location
The experiment was carried out at the Erra Research Station to improve the mountain goat breed at the Syrian General Authority for Scientific Agricultural Research for the seasons 2019-2020.
The experiment was applied to forty females of milking mountain goats, which were divided into two parts, Control (20), and the experiment (20). A ratio of (0.010% probiotics) was added from the concentrated diet, in addition to the filling ration. Which lasted until the end of the milk production season for a period of 126 days, periodic milk control readings during the season were taken for each goat?

The fodder feed
Ingredients: (Table 1)shows the components of the fodder feed provided to milking mountain goats for both the control and the experiment. The cost of the daily fodder ( Table 2) the cost of 1 kg daily fodder used for the experiment and control (SP/1 kg). Chemical composition (Table 3)

Data Analysis Method
The study relied on descriptive statistics methods to describe some of the study variables, such as the mean, standard deviation, and standard error.

Results And Discussion

The effect of using probiotics (Table 5,6) shows the results of the analysis of variance and some descriptive indicators:

Conclusion
There is a positive effect of using a probiotic growth stimulator in fodder mixtures for female mountain goats on the most important productivity indicators of dairy goat females compared with the control, except for the milking period indicator, which is in agreement with Ghorbani et al. [4] that adding probiotics to the forage diets improves the level of Productive indicators through improving the digestion process, and also helps to show the inherent genetic potential of the animal fed on it, and Rombeau etal. [5] agrees that the addition of probiotics increases the production of volatile fatty acids and medium and short chain acids that are mainly involved in the composition of goat milk , As it was found that the use of probiotic growth stimulator in the feed had a significant effect on the 0.001 level in favor of the experiment for the control
