    Evaluation of sexual behavior of stallion (Arabian versus Barb) during breeding season in Algeria
    (Agricultural Research Communication Centre, 2020-09-20) HOUSSOU Hind; BOUZEBDA AFRI F; BOUZEBDA Z; BENIDIR M
    This study was carried out at National Haras of Tiaret (west of Algeria) to understand and to compare the normal sexual behavior and libido of stallions (Arabian vs Barb) while mounting a mare in estrus. Eighty-four stallions were divided into two groups from 5 to 24 years of age (n=47 Arabian; n=37 Barb). Results revealed significant differences between Arabian and Barb stallion: in sniffing(p<0.001), libido score (p<0.05), flehmen response (p<0.05), time to first mount with erection (p<0.05), number of mounts to ejaculation (p<0.05) and mount time for ejaculatory (p<0.01). These stallions were exactly tested in the same place and conditions allowed us to discard any side effects due to animal management or any other confounding bias. Our study provided us the knowledge of sexual behavior under Algerian environmental conditions and the distinction between Arabian and Barb stallion in their sexual behavior expression

    Genetic and non-genetic factors affecting dystocia in cattle, Algeria
    (Genetics & Biodiversity Journal, 2023-01-02) HOUSSOU Hind; BENSALEM Mounira; BELHOUCHET Hanene; HEZAM Houcemeddine
    Dystocia or calving difficulties carry a guarded prognosis for life or future fertility in affected females; cattle are considered to be the most affected species having the highest incidence rate of dystocia. In this study, we used two different approaches to identify the causes of dystocia in cattle raised in Souk-Ahras wilaya during the period (2018 - 2020). First, a survey was conducted on 32 farms to collect data. Then, 103 Montbeliard cows’ pelvic were taken. Our findings indicated that the dystocia was greater in the Montbeliard breed (40%) than in the other breeds (P < 0.05). The most common causes of Dystocia reported by vets were narrow pelvic 45%, uterine torsion 31%, uterine inertia 23%, and other causes 1%. The parity number was more frequent in primiparous with a rate of 62% than in multiparous 38% (P < 0.05). Dystocia was significantly more frequent in artificially inseminated (AI) cows than in natural breeding (NB) cows (P < 0.01). The dimensions of the pelvis were the width of the hips (53.85±5.06 cm), the width of the trochanters (47.77±6.05 cm), the width of the ischia (29.81±7.02), the length of the pelvis (54.42±2.29) and the Body Condition Score (2.51±0.46). In general, a significant correlation (P < 0.01) between chest girth and these measurements (Body Condition Score, live weight, hip width, trochanter width) was reported. It was concluded that the most common cause of dystocia in Algeria was mainly due to narrow pelvic or fetal-pelvic disproportion, so the use of pelvimetry will be a routine examination to predict dystocia in cattle.

    Dairy production in the indigenous Arbia goat breed and growth performance of their kids in Algeria
    (VETERINARSKA STANICA, 2023-06-22) HOUSSOU Hind; LABIOD Abir; RAMADANI Aya; KHENENOU Tarek
    Knowledge of dairy potential is essential to create products that fully express their genetic potential. This study was carried out on 94 Arbia adult goats and 65 kids (n=195) (February – May 2022) in the wilayas of Souk-Ahras and Tebessa with the aim of estimating the dairy potential of the breed, and the daily gains (ADG) between birth and 90 days of age. The data revealed that daily milk production (n=94) was 0.89±0.85 litres per day. Milk quality was characterised by an average composition of 3.2% fat, 13.46% total protein, 17.28 % total dry extract, 0.78% salt, pH 7.08±0.01, acidity 17.7°D, density 1032 and protein/fat ratio 4.29. Regarding growth performance, the average birth weight was W0 = 1.80±0.61 kg, while the average at 90 days was W90 = 10.05±2.02 kg, which corresponds to an overall daily weight gain of ADG0-90 = 91.66 g/day. The study showed that birth weight was not affected by sex (P>0.05), though males grew faster after weaning (P<0.05), and the performance aspect carried out by some physicochemical characteristics of milk was affected by area (P<0.05). The study results indicated that the local breed goat had good production dairy performance and goat kids demonstrated acceptable potential for meat production under the semi-arid Algerian environmental conditions. Therefore, it would be suitable to check for the presence of lactogenic plants on the pastures of these breeders to enhance production.

    Measurement of the reproductive efficiency of Arabian stallions intended for AI in Algeria
    (Indian Council of Agricultural Research, 2021-09-08) HOUSSOU Hind; BOUZEBDA AFRI Farida; BOUZEBDA ZOUBIR; BOUDJAKJI Abdelkarim
    The aim of this study was to determine the reproductive efficiency of Arabian stallions presented at CNIAAG and selected for an artificial insemination (AI) program. Ten Arabian stallions between 8 and 15 years of age were subjected to an analysis of the reproductive parameters. Assessment of sexual behaviour, testicular measurements and appreciation of semen quality collected with the help of artificial vagina was done. There was a significant correlation between the sexual behaviour, the spermatic parameters and the testicular parameters, especially between the number of mounts with the motility and the daily sperm ejaculated (DSP) (r=0.99). The testicular volume total and mounts was highly correlated to the average volume of ejaculate (73.33 ± 60.27 ml) and total Sperm concentration (billions) (r=0.99) which allowed us to produce 38 straws intended for the preservation. Based on the results, it is concluded that there is a positive correlation between (TSW) and motility, the various measurements of testis size were highly correlated with each other; and consequently to predict the fertility of the stallions from the testicular measurements.

    HORMONAL LEVELS AND FOLLICULAR DYNAMICS IN RELATION TO THE OESTROUS CYCLE IN BARB AND ARABIAN MARES, ALGERIA
    (SCIENDO, 2021-06-29) HOUSSOU Hind; BOUZEBDA AFRI Farida; BOUZEBDA Zoubir
    This current study is an effort to understand the hormonal and follicular growth in the Barb and Arabian mares during the oestrous cycle; as mares are unique creatures. A total of 53 mares with 97 oestrous cycles were studied. The mares with a mean age of 10.38 ± 4.55 were examined by ultrasonography every day during their breeding season (2017). Two blood samples from each mare (n = 24) were obtained for progesterone (P4), oestrogen (oestradiol-17 beta) and follicle-stimulating hormone (FSH) determinations. The data revealed that the duration of the oestrous cycle was between 19 to 22 days. The pre-ovulatory follicle grew (3.02 ± 1.04) millimetre per day. The rate of cycles exploited in the mare (Arabian versus Barb) for conception was significantly different (P < 0.001). The maximal diameter of the follicle was 50.00 millimetre. The serum progesterone levels (P < 0.01) in mares were significantly higher in the luteal phase than those recorded during the time of oestrous. However, the levels of oestradiol and for FSH did not significantly change during the oestrous cycle in the mares. Determining the association between the size of the follicle and the hormone profiles were the most reliable criterion in the prediction of ovulation.

    A Retrospective Study of Arabian Stallion Fertility Used in National Stud Farm of Tiaret (West of Algeria)
    (IDOSI Publications, 2018-03-15) HOUSSOU Hind; BOUZEBDA AFRI Farida; BOUZEBDA Zoubir
    The aim of this paper to evaluate the stallion fertility in advance and to aid breeding management. The collection of a historical information about the Arabian stallions adults (n=101) and 495 mares with range age between (8 and 26) years in the national stud farm of Chaouchoua Tiaret. Fertility was measured using three endpoints: foaling rates (FR), percent pregnant per cycle (PC) and percent pregnant per season (PR) during (2003-2013).The pregnant per season rate (PR) was of 84 % The foaling rate (FR) was of 80%, the pregnancy cycle rate (PC) was of 96 % ; a strong correlation existed between the number of mares mated and (PC) (r= -0.59; p<0.01). We conclude that breeding records existed in many forms (foaling, pregnancy per cycle, or per season rates), but there is still a need to develop tests that can predict fertility with a reasonable degree of certainty before the stallion has begun his breeding career.
