“…Body temperature and signs of post-partum metritis were recorded for each cow at each follow-up to detect any puerperal metritis affection. If any experimental cases presented fever, they would receive systemic treatment with 10 mg/ kg of body weight of amoxicillin for 3-5 consecutive days (Amin et al, 2021).…”

“…Retained placenta (RP), a prevalent complication in animals after parturition, increases the risk of uterine infections and infertility, increases calving interval and reduces milk yield, causing great adverse efficiency for reproductive and productive performance in dairy cows (Amin et al, 2021; Gohary & LeBlanc, 2018; Mahnani, Sadeghi‐Sefidmazgi, Ansari‐Mahyari, & Ghorbani, 2021; Qu et al, 2014). The complicated aetiology of RP is affected by the management of environmental causes in herds and the physiological and pathological states of cows, including age, parity, heredity, hormones, nutrition and the condition of the calves, such as stillbirth and twinning (Mahnani, Sadeghi‐Sefidmazgi, Ansari‐Mahyari, Ghorbani, & Keshavarzi, 2021).…”

“…Several studies have concerned RP in dairy cows; however, till now, no single treatment has achieved comprehensive approval (Amin & Hussein, 2022). Therefore, veterinary practice includes several protocols for treatment of RP, such as the manual removal of the foetal membranes, the use of antimicrobials either systemically or intrauterinally administered (Amin et al, 2021) or the use of ecbolic drugs. Recent approaches for treatment include the use of enzymes that promote placental shedding (Drillich & Heuwieser, 2007; Guerin et al, 2004; Gulia et al, 2022).…”

The study aimed to evaluate the effect of α‐chymotrypsin on placental separation as a treatment protocol for retained placenta (RP) in dairy cows and its effect on reproductive performance after placental shedding. The study was conducted on 64 crossbred cows that suffered from retained placenta. Cows were divided into four equal groups: group I (n = 16) treated with prostaglandin F2α (PGF2α); group II (n = 16) treated with PGF2α in combination with α‐chemotrypsin; group III (n = 16) treated with α‐chemotrypsin only and group IV (n = 16) treated by manual removal of the RP. Cows were under observation after treatment till placental shedding. Placental samples were taken from the non‐responsive cows after the course of treatment and examined to observe the histopathological changes in each group. Results revealed that the time of placental dropping showed a significant decrease in group II compared to other groups. Histopathological examination of group II shows that collagen was found as fewer fibres in scattered areas and necrosis appeared as numerous areas widespread in the foetal villi. A few inflammatory cells were infiltrated in the placental tissue and the vascular changes appear as mild vasculitis and mild oedema. Cows in group II have rapid uterine involution, decreased risk of post‐partum metritis and improved reproductive performance. It is concluded that PGF2α in combination with α‐ chemotrypsin is the recommended treatment for RP in dairy cows. This recommendation is warranted, as this treatment was successful in achieving rapid placental shedding, rapid uterine involution, a decreased risk of post‐partum metritis and improved reproductive performance.

“…There are several safety risks associated with milk that originate from exposure of milk to chemicals, microbial contamination, illegal additives, aflatoxins [ 7 – 9 ], veterinary drugs [ 10 , 11 ] and heavy metals [ 12 ]. Heavy metals are one of the most dangerous environmental pollutants that contaminate the milk creating significant risk to consumers [ 13 ].…”

Heavy metals are one of the most toxic chemical pollutants of the environment. Their hazards not restricted to human but extend to animal productivity and reproductively. The present study aimed to assess the impact of grazing around industrial areas on the levels of copper (Cu) and aluminum (Al) residues in milk samples collected from dromedary she-camels and studying their effects on some ovarian hormones. In addition, the study aimed to investigate methods of removal of the toxic concentrations of these heavy metals in milk by applying different technological processes. Blood and milk samples were collected from 30 dromedary she-camels, 15 grazing in non-industrial areas (group A) and 15 grazing in industrial areas (group B). Detection of the levels of these heavy metals in milk was done. Ovarian hormones investigation on the blood was performed. Different technological processes such as boiling, skimming and fermentation were applied to all contaminated samples to reduce the toxic concentrations of these heavy metals. Results revealed that all examined milk samples in both groups contained Cu, while 40% of group A and 100 % of group B contained Al residues with different concentrations. The levels of Cu and Al residues in samples of group A not exceeded the maximum residual limit (MRL) set by World Health Organization (WHO) while 60% and 100% of milk samples in group B contained Cu and Al residues exceeded MRL, respectively. Technological processes induce variant changes in the levels of these metals in milk. Heat treatment of milk in Al vats leads to leaching of Al from containers to the milk causing significant increase in Al load, while Cu level was not significantly affected. Boiling in stainless-steel containers decreased the levels of Al and Cu but in non-significant levels. Regarding skimming process, small amount of Cu and Al escaped into the skimmed milk while greater amount were recovered in the cream. Fermentation by probiotic bacteria showed that milk fermentation has non-significant effect on Cu and Al levels. Investigation of ovarian hormones (estrogen and progesterone) revealed presence of a signification reduction in the levels of these hormones in group B compared to group A. In addition, a negative correlation was found between these heavy metals and ovarian hormones concentrations in the blood. It is concluded that grazing of dromedary camels around industrial areas induce heavy metals toxicity represented by excretion of these metals in milk and significant reduction on ovarian function showed by reduction of estrogen and progesterone levels. Technological processes such as skimming decreased the levels of Al and Cu residues in milk.
