“…The difference in this result would be due to the technical means of assessment (determination of live weight by barymetric formulas), the heterogeneity of the studied animals (sex, age, fattening period), and the method of estimating carcass yield (true dressing vs. commercial dressing). On this last point, our result is estimated at 56%, which is rather close to the yield reported by Bouzebda Afri et al ( 2007) and Gherissi et al, (2013).…”

“…Moreover, the high variance level of this parameter shows a high likelihood of possible production improvement of this population, which was originally never put to selection. In this regard, the live body weight represents the result of calves growth, which is meanly dependent on the milk production of the dams and secondary to the quality of forage, for which the intake increases after 3 months(Handcock et al, 2021;Gherissi et al, 2013). The empty live weight observed in this study varied from 202.52 Kg to 589.99 Kg, which indicates that a selection on this quantity parameter would be highly recommended as part of a genetic improvement in beef performance.…”

The present study consists of an assessment of the slaughter performance, body composition, and carcass traits of 51 native Algerian bulls 'Brune de l'Atlas' belonging to four ecotypes, aged 1 to 2 years, and fattened for a period of 4 to 6 months. Its main objective is to provide an estimate of the mean parameters related to meat production in terms of quantity and quality, including live weight and body composition, slaughter yield, conformation, fatness, and fineness of carcasses. The average live weight is 366.56±92.56 kg. The average true and commercial dressing percentages are 60.11±11.09% and 56.1±10.04%, respectively. The studied animals produce lean carcasses with a low proportion of body fat. The fattening index and the score of the fattening state are 5.9±3.86% and 14.81±7.67, respectively, and the score of the fattening state is 1.85±0.83. As for the carcass conformation, it is relatively insignificant. The thigh compactness index is 4.82±1.59, the carcass compactness index is 1.55±0.37, the buttock compactness index is 0.69±0.02, and the average EUROP carcass classification score is 1.86±1.04 (≈O class). Significant positive correlations were found between body live weight and carcass weight, 5th quarter and carcass conformation, and negative correlations with slaughter yield and body fineness. These results showed an interesting level of slaughter performance of the local Algerian cattle population. The latter could contribute to satisfying the growing demand for red meat and reducing the costs of red meats imports through the improved valuation of its butchering performance by implementing genetic, nutritional, and other management practices improvements.

“…Two breeds of female dromedary camels were chosen due to the majority admitted to the veterinary educational clinic of Qassim university KSA. During the mating season, proper food sources paired with ambient climate can increase ovarian activity, improve body condition scores, and maintain the ideal level of gonadotropins released from the anterior lobe of the hypophysis in she-camels (Ainani et al 2018;Gherissi et al 2020). Several cysts may develop in and around the ovaries, though some cysts are discovered by accident during an ultrasonographic check and others are linked to problems with fertility (Iliyasu et al 2016).…”

“…Ovarian activity in dromedary camels increases during the breeding season in the winter and spring and is influenced by plentiful food sources, favorable weather, and the physical condition of the female (Ainani et al 2018;Gherissi et al 2020). Paying attention is obviously necessary because ovarian inactivity may significantly affect infertility issues and interfere with reproductive effectiveness.…”

“…However, some research is being done to better understand dromedary reproductive issues and increase reproductive effectiveness (Skidmore et al 2005). The negative physical condition was given as the cause of the female camels' inactive ovaries during the breeding season (Gherissi et al 2020). Female camels with inactive ovaries are frequently presented to the clinic with a history of multiple unsuccessful mating attempts or refusal to mate.…”

Numerous researchers have proposed work in dromedary camel immunity. It has not before been described how autoimmune etiology is involved in cystic and inactive camel ovaries. To specifically identify ELISA technique to measure anti-ovarian antibodies (Anti-OAB) in the serum, sixty female dromedary camels with various cysts and inactive ovaries during the breeding season were used. For the first time, the values of ELISA are objectively displayed in the current study. Sex evaluations were performed on each sample using the newly designed In-House indirect ELISA. Three are related to the cutoff value, two are related to the sample's initial dilution, and the last reading is related to the antibody index. The values of the Majaheem breed with follicular and luteal cyst were significantly greater than those of healthy she-camels in terms of serum OD of primary dilution; cut-off (antibody titer) value and calibrated antibody concentration against ovarian protein (P<0.05 and P<0.01, respectively). Concerning antibody index, the data demonstrated a significant difference between the healthy she-camel and Majaheem breed with follicular and luteal cyst (P<0.05), Majaheem breed with hemorrhagic cyst (P<0.01) and Majaheem and Waddah breeds with inactive ovary (P<0.05). Results exhibited a significant decrease in estrogen (P<0.001) and FSH levels (P<0.05) comparing to normal control group in the serum of Majaheem breed with follicular and luteal cysts and inactive ovary. It is recommended that more study be done on the blood-follicle barrier to comprehend how abnormality develops in ovarian she-dromedaries.
