“…Hence, this may enhance the implantation process of embryos under chronic thermal stress. El-Tarabany et al [ 22 ] suggested that FA supplements considerably increased serum progesterone concentrations throughout the early stages of pregnancy, which is in line with our findings. In this regard, Starbuck et al [ 25 ] found a positive relationship between plasma progesterone levels and pregnancy maintenance at week five of pregnancy.…”

“…The purpose of this study was to see how FA supplements affected the progesterone profile and blood chemistry of heat-stressed Holstein cows during the first month of pregnancy. Progesterone is thought to have an important role in the implantation and growth of embryos in the early stages of pregnancy [ 22 ]. Furthermore, cows exposed to summer heat stress often have a considerable reduction in progesterone levels [ 23 ].…”

The aim was to elucidate the impact of oral folic acid (FA) supplements on progesterone profile, blood metabolites and biochemical indices of heat-stressed Holstein cows during the early stage of pregnancy. The study lasted from the day of artificial insemination through the end of the fourth week of pregnancy. The first group (CON, n = 17) received 0 μg of FA/kg BW as a control. The second and third groups received oral FA doses of 5 (FA5, n = 19) and 10 (FA10, n = 20) μg kg−1 BW, respectively. At the 2nd and 3rd weeks of pregnancy, the FA10 group had greater progesterone levels than the CON group (p < 0.05). The FA10 group had a greater progesterone level than the FA5 and CON groups at the fourth week of pregnancy (p < 0.01). The FA10 group had higher folate levels than CON group during the first three weeks of pregnancy (p < 0.01). Both FA-supplemented groups had significantly greater serum folates than the CON group by the end of the fourth week of pregnancy (p < 0.01). At the 2nd and 4th weeks of pregnancy, the FA10 group had greater levels of serum glucose and globulin than the CON group (p = 0.028 and 0.049, respectively). Both FA-supplemented groups had greater serum growth hormone (GH) levels at the 4th week of pregnancy (p = 0.020). Additionally, the FA10 group showed significantly higher levels of IGF-1 at the 2nd and 4th week of gestation (p = 0.040 and 0.001, respectively). FA supplementation decreased the levels of non-esterified fatty acid (NEFA) at the 2nd and 4th week of gestation (p = 0.020 and 0.035, respectively). Additionally, the FA10 group showed significantly higher pregnancy-associated glycoprotein (PAG) levels at the 2nd and 4th week of gestation (p = 0.005 and 0.001, respectively). In conclusion, oral FA supplementation (10 mcg kg−1) in the first month of gestation improved the progesterone profile, as well as blood folates, PAG, GH, and IGF-1 concentrations in heat-stressed Holstein cows. These findings could be useful in developing practical strategies to keep dairy cows’ regular reproductive patterns under heat stress conditions.

“…A possible explanation is that there were no changes in weight gain because the deals involved the same total calories and the same % of crude protein in the diet. The results of this study agreed with [10]. and did not agree with [11].…”

“…While the flaxseed oil treatments led to an increase in cholesterol concentration, as the third treatment was 84.00 mg/dL significantly (p≤0.05) over the control treatment 74.00 mg/dL and non-significantly superior to the second treatment 81.00 mg/dL significant. The reason for this increase is that this Fat added to the diet increases the concentration of cholesterol in the blood [10]. Dosing with flaxseed oil led to an increase in blood glucose, as the third treatment was significantly superior (p≤0.05), reaching 66.66 mg/dl over the first and second treatments, 53.33 and 54.66 mg/dl, respectively.…”

The goal of this research was to determine the effects of various doses of flaxseed oil on ewe body weight, growth characteristics, and selected biochemical and hormonal blood characteristics. This research was carried out in the animal science department at the University of Tikrit’s College of Agriculture between October 6th, 2022, and September 1st, 2022. There were a total of 17 female Awassi sheep, ages 1-2, with an average live weight of 56.41 kg, and they were randomly assigned to one of three groups. To the ewes, flaxseed oil was administered at a rate of 0%, 6%, and 8% of the dry matter weight in the three different groups. The ewes were grazing daily, in addition to providing a supplementary diet at the level of 2.5% of body weight, consisting of 14.98 protein and 14.22 MJ/kg dry matter as energy. At the end of the experiment, there were no significant differences (P>0.05) between the treatments in ewes’ weights, the percentage of packed blood cells, the number of white blood cells and platelets, and the values of total protein, albumin, urea, and creatinine, while the control treatment was the least significant (P≤0.05). of the second and third treatments, which had the highest numbers of red blood cells (5.79, 6.61 and 7.72) 106cells/ml3 and hemoglobin (9.06, 9.80 and 10.20) mg/dl, respectively. While a significant decrease (P≤0.05) was, observe for the activity of AST, ALT and triglyceride enzymes for the third treatment compared to the control treatment. The third treatment was significantly superior (P≤0.05) in the value of blood globulin, glucose and cholesterol 1.90 g/dl, 66.66 and 84.00 mg/dl, respectively.

“…Moreover, folate is an antioxidant that is capable of scavenging free radicals and their metabolic products to protect lipids from oxidative damage and maintain normal cellular physiology (2) . Similarly, during the early stages of pregnancy, the addition of FA to the maternal diet leads to significantly higher serum antioxidant activity (glutathione and superoxide dismutase) in ewes compared with the non-treated control group (3) . Therefore, a sufficiently high FA level is crucial to embryo development and rapid growth during gestation as well as the early stage.…”

The present study was undertaken to evaluate the influence of rumen-protected folic acid (RPFA) on slaughter performance, visceral organ and gastrointestinal tract coefficients, and meat quality in lambs. Sixty-six lambs from 120 Hu ewes were selected based on body weight and maternal diets and then assigned to six groups using a randomised block experimental design in a 3 × 2 factorial arrangement. The first factor was folic acid (FA) as RPFA in the maternal diet (0 mg/kg (M0F), 16 mg/kg (M16F) or 32 mg/kg (M32F) on DM basis). The second factor was FA in the lambs’ diet from weaning until slaughter (0 mg/kg (OC) or 4·0 mg/kg (OF)). The results indicated that the addition of 16 mg/kg FA to the maternal diet increased pre-slaughter weight (PSW), dressing and meat percentage, the reticulum and omasum coefficients, length of the jejunum and ileum, tail fat and perirenal fat coefficient and a* value of the meat colour. The addition of RPFA to the lambs’ diet increased PSW, dressing and meat percentage, eye muscle area, abomasum weight, weight and length of the small intestine, but reduced the coefficients of tail fat. An M × O interaction was observed for the weights of heart, lungs, rumen and total stomach, weight and coefficient of omental fat and the girth rib value. Collectively, RPFA in the maternal and lambs’ diet improved slaughter performance and meat quality by stimulating the morphological development of the gastrointestinal tract and the distribution of fat in the body.
