“…The THI values in our study agree with Kassab et al (2017) who reported that the THI values from May to September in New Valley recorded between 75.39 to 82.12, these results indicating that animals under heat stress. Likewise, the average values of THI were between 79.43 to 85.46 at 02:00 pm and 69.04 to 74.14 at 10:00 pm in the new valley governorate during summer season indicating that animals under severe stress zone at 2:00 pm and heat stress at 10:00 pm (Kassab et al, 2020). The present data indicated that animals were under heat stress according to (Du Preez et al, 1990).…”

This study aimed to investigate the effects of betaine supplementation on some hematological and physiological parameters of Aberdeen Angus cows. Twelve cows were divided randomly into two equal groups (6 cows each) and each group was treated for 150 successive days. All experimental animals were fed 60% of their requirements as a concentrate mixture and the rest of other requirements was covered from wheat strew adlibitum. In addition to basal diet, animals in experimental group were supplemented with 30 g betaine hydrochloride per day. Air temperature and relative humidity were recorded during the experimental days to calculate the current temperature-humidity index (THI). Blood samples were collected during experimental period from jugular vein. Rectal temperature (RT), pulse rate (PR), respiration rate (RR), skin temperature (ST) and hair temperature (HT) were recorded during the experimental days. The obtained results showed that the average values of THI were between 71.6 to 74.78 at 08:00 am and 77.09 to 83.01 at 02:00 pm during the experimental period which indicates exposure of animals to heat stress. There were no significant differences among groups in WBC, HCT, MCV, MCH, MCHC and PLT. Moreover, RBC and HGB was higher (P < 0.05) in betaine group than control. adding betaine had no significant decrease in RR, ST, HT, and ET. While significant decrease in RT and PR was observed at 02:00 pm of experimental animal. It is concluded that betaine may be improved some hematological parameters and thermoregulatory responses of Aberdeen Angus cows under New Valley arid areas.

“…These results agree with Raheja et al (2018) who noted that the first service conception rate in BET group was higher than CG. Likewise, the first service conception rate was significantly (P<0.05) higher in Aberdeen Angus cows treated with antioxidant when compared to CG under New Valley hot conditions (Kassab et al, 2020).BET supplementation during HS of summer season is an effective strategy to enhancing the reproductive efficiency and antioxidant activity of Aberdeen Angus cows under HS conditions. In a retrospective study, Amundson et al (2006) observed a significant decrease in the CR in cows during HS (62%) when the THI values were higher than 72.…”

“…According to estimates, 5-20% and 10-40% declines in feed consumption and production of dairy cattle, respectively, are attributable to HS conditions (Babinszky et al, 2011). Additionally, HS is the major factor contributing to poor fertility by causes decreased estrus expression, decreased fertilization rate, and increased embryonic mortality in cows during HS which leads to an economic deficit in dairy production (Kassab et al, 2020). HS can adversely affect pregnancy rates in cows inseminated during HS (Turk et al, 2015).…”

This work studied the effect of betaine (BET) supplementation on the metabolic, hormonal and reproductive efficiency of Aberdeen Angus cattle under heat stress (HS) conditions. Twelve cows were assigned randomly into two equal groups (6 cows each). Treatments included: control group (CG) and BET group supplemented with 30 g BET/h/d. Total antioxidant capacity (TAC) and biochemical parameters were measured monthly for 150 days from the start of treatment till pregnancy occurs. The results showed a significant increase in albumin, globulin, T3, and T4 in the BET group compared to the CG. Whereas the concentrations of ALT, AST, and cortisol decreased (P<0.05) significantly in BET group than CG. TAC was significantly greater (P<0.05) in BET group than CG. The elevated conception rate was recorded for BET-treated cows (100%) compared with (83.33%) extent of CG. The number of services required per conception was lower in BET-treated cows (1.17) compared with CG (1.67). The presented results concluded that BET could enhance metabolic, antioxidant status and reproductive efficiency of Aberdeen Angus cows during HS conditions of summer season.

“…El-Khadrawy et al (2008) suggested that buffaloes have (internal parasites) (Fasciola) recorded lower concentrations of blood Zn, Cu, Fe and Se compared to healthy animals. Kamada, (2017); Kassab et al (2020) reported that supplementation of selenium to diet in dairy and beef cows led to increasing in progesterone and estradiol concentrations during estrous cycle. Sadek and Shaheen (2015) showed that there is increasing in serum progesterone in Baladi cows during postpartum after treatment with Ivermectin (anti-parasites) for up to 3 months.…”

The current investigation was designed to determine the effect of treatment with anti-parasites (Ivermectin) on mastitis and postpartum reproductive efficiency measurements in Egyptian Baladi cows. Twenty-four of the cows included in this study were split into two groups. The first group (n = 12 cows) was injected two months prepartum with two doses (15 days inter-treatment) of IVOMEC® Plus solution subcutaneously behind the shoulder, 1ml/50kg live body weight as prescribed by the manufacturer, whilst the other group (n = 12 cows) was used as a control group. The present results revealed that the incident rate of mastitis in treated cows’ group was significantly (P < 0.05) lower (16.7%) than control cows’ group (41.7%). The conception rate in treated cows’ group was significantly (P < 0.05) higher (66.7%) compared with (33.3%) in control group. The time from calving to conception in treated cows was significantly (P < 0.05) lower 86.5 ± 11.4 days compared to 123.3 ± 13.2 days in the control group. The occurrence rate of anestrous cases was significantly (P < 0.05) lower (8.3%) in treated cows than (control group) (25%). In conclusion, the current study indicates there is an association between treated cows with anti-parasites (Ivermectin) two months prepartum and incidence rate of mastitis addition an improvement in the reproductive performance in treated cows relative to untreated cows. Therefore, the current study recommends the herdsmen treats their cows with anti-parasites (Ivermectin) during the prepartum period for less mastitis incidence rate and better reproductive efficiency.
