Prevalence of Subclinical Mastitis in the Local Goats in the Province of Laghouat (ALGERIA)

Subclinical mastitis is a disease of the udder that passes mostly unnoticed. Or several germs associated with it and their presence in milk constitutes a major risk to consumer health. Our study aims to determine the prevalence of subclinical mastitis in local goats in Laghouat region (Algeria). We undertook a study based on the detection of sub-clinical mastitis by Califirnian Mastitis Test (CMT) in 60 goats aged 1 to 9 years and weighing 18 to 45 kg of live weight and whose lactation number varies from 2 to 8. We found a prevalence of subclinical mastitis reaching 46.6%. A clearly significant difference (P <0.05) is reported on this prevalence compared to age. The highest rate is recorded especially in goats aged between 3 to 7 years with 62% of detected subclinical mastitis, followed by the older goats (over 7 years) with a prevalence of 27%, and at the end the youngest goats (1-3 years) with a prevalence of 11%. A significant difference was also recorded between the different lactation ranks (P <0.05). The goats having the highest rank of lactation were most affected by subclinical mastitis. Prevalence of 46%, 31%, 11% and 8% respectively are found for the 6th rank of lactation and more, 4 lactations, 5 lactations and 1 lactation. We noticed that the majority of diagnosed mastitis were caused by poor hygiene conditions. This study allows us to conclude that there is a high prevalence of subclinical mastitis in the local goats in the province of Laghouat (Algeria)

Estrous cycle length in the algerian arbia goat: exfoliative vaginal cytology and serum progesterone levels

This study aimed to estimate the estrous cycle length of the Algerian Arbia goat in Northern Algeria. For this, eighteen (18) Arbia goats, aged between 2 and 6 years, were used in our work that took place in the experimental farm of the Saad Dahlab University (Blida, Algeria). Blood samples were taken from each goat twice a week (at a 2 or 3-day interval) for 3 months. The serum progesterone concentration was determined by Radio-Immuno-Assay. Smears of the vaginal mucosa were taken at the same time as the blood samples. The predominance of superficial cells on the smear of the vaginal mucosa as well as a serum progesterone level less than 1 ng/mL expressed the return to estrous which was considered the beginning of a new cycle. A negative correlation was observed between the percentage of superficial cells (SC) and serum progesterone (P4) levels in all goats. Our results showed a significant difference (P<0.05) between the means of different cycle lengths obtained among the females. In addition, normal cycles had an average of 20.11±1.85 days (17-25 days) representing 59.6% of cycles. Besides, a large number of short cycles (<17 days) with an average of 14.41±1.51 days were found representing 25.5% of recorded cycles. The number of long cycles (>25 days; with an average of 32.14±5.58 days), represented 14.9% of recorded cycles. Following these results, it can be concluded that the local goat in Northern Algeria had different types of cycles (normal, short, and long) with a large percentage of normal cycles

IMPACTS OF THE SITUATION OF SLAUGHTER HOUSES ON THE PERSISTENCE OF PARASITIC DISEASES IN THE DEPARTMENTS DJELFA AND TIZIOUZOU ALGERIA

A preliminary investigation was conducted on thirty slaughterhouses and killing of two different departments of Algeria, Tizi-Ouzou is located in the north of the country characterized by a humid climate, very cold in winter and high temperatures in summer and Djelfa region is an internal region of the country, it is defined by its dry climate in summer and sandstorms, cold winter, the objective of this work is to shed light on the situation of places sacrifice of the animals, which can be a source of parasitic diseases, we mention that hydatid disease is expanded in our country on a large scale due to the presence of dogs in these places, and many other bacterial diseases. Our results have reached a deplorable situation to irreversible if we do not perform repair deficiencies and problems found in the heart of the investigation. An architectural structure and a carefully planned infrastructure to international standards calculated with good administrative organization for internal and external, and compliance with all standards and hygiene with regular monitoring and control of these places will change the logging actual situation and to minimize the maximum transmitting several diseases, and decrease the rate of prevalence of parasites especially
