“…Compared with those fed a diet supplemented with saturated fatty acids (SFAs), dairy cows fed a diet supplemented with flaxseed oil showed increased folliculogenesis [14]. Furthermore, the supplementation of ewes with omega-3 PUFAs from fish oil improved the growth of their follicles and corpus luteum and increased the synthesis and secretion of estrogen and progesterone [12], which ultimately improved the quality, growth, and development of the embryos [15,16]. The dietary supplementation of α-linolenic acid (ALA) increases its conversion into eicosapentaenoic acid (EPA), which leads to the formation of 3-series eicosanoids and increases the synthesis and secretion of progesterone [6].…”

Background and Aim: Flushing with the manipulation of fatty acids, particularly polyunsaturated fatty acids, like linoleic and α-linolenic acids in the ration, is a strategy to raise the nutritional status of the female mammals to improve ovarian function and follicle development. This study was designed to investigate the effectiveness of flushing supplementation with different types of polyunsaturated and saturated fatty acids in stimulating follicle growth and development during estrus in Ettawa Grade does with a low initial body condition score (BCS ≤2). Materials and Methods: Eighteen Ettawa Grade does in the second parity, with an average body weight of 32.11±2.19 kg, were divided into three groups according to the fatty acid supplemented to their ration: (i) About 2.8% lauric acid flushing (group); (ii) 2.8% linoleic acid flushing (LA group); and (iii) 2.8% a-linolenic acid flushing (ALA group). The ration was formulated to be isocaloric (total digestible nutrient = 77%) and isonitrogenous (crude protein = 15%). The experiment was conducted for 35 days; that is, 14 days for acclimatization and synchronization of the estrous cycle and 21 days for fatty acid flushing until the appearance of the next estrus. A completely randomized design was applied. Results: According to the results, none of the different fatty acids in the ration affected the nutrient intakes, BCSs, average daily gains, and plasma glucose, cholesterol, and progesterone concentrations of the three groups of does. However, the BCSs (by 0.8-0.9) and the plasma cholesterol concentrations were higher after fatty acid flushing for 21 days than before the flushing period. The ALA group had the highest number of large-sized preovulatory follicles, whereas the LAURIC group had the highest plasma estradiol concentration during estrus. All three groups had similar plasma progesterone concentrations during estrus after fatty acid flushing. Conclusion: Flushing supplementation with 2.8% ALA from flaxseed oil gave the best results in terms of stimulating the highest number of large-sized preovulatory follicles in Ettawa Grade does.

“…This statement was in line with stated that fat has special function for increasing milk quality and reproduction performance 26 , meanwhile another researcher reported that fat with specific Polyunsaturated Fatty Acids (PUFA) has very strong correlation with reproduction 27 . Supplementation with PUFA in the flushing diet could stimulate steroid hormone and follicle development 28 , increasing of fertilization and embryo development 29,30 and also progesterone concentration 31 . At the end of pregnancy, ewe need high energy diet in order to support the fastest growing embryo 32 .…”

Background and Objective: There is very rare information regarding data of reproduction performance of small ruminant with different management flushing program in Asian countries. The aim of this study was to evaluate the implementation of flushing diet program containing lemuru fish oil with time management difference, by evaluating the reproductive performance of local Garut ewes. Materials and Methods: Twenty of garut ewes (average body weight 30.06±6.20 kg) were used in this experiment using Completely Randomized Block Design (CRBD), in four treatments with five animals of each treatment. The treatments were without flushing (F0 as control), flushing at the beginning of mating (F1 = 2 weeks pre-mating until 2 weeks just after-mating), two times flushing (F2 = F1 plus 4 weeks flushing during mid gestation) and three times flushing (F3 = F2 plus 2 weeks flushing at the end of gestation and 2 weeks after parturition). The ratio of flushing or basal concentrate to forage was 70:30. Basal concentrate was given during untreated. Nutrients consumption, body condition score (BCS), average daily gain (ADG), feed efficiency ratio (FER) and reproduction parameters were evaluated. The data of sex ratio and birth type were expressed descriptively. Results: The results showed that the treatment had significant effect (p<0.05) on crude fat consumption, total digestible nutrients (TDN) and changes of BCS values, but had no effect on other nutrients consumptions. All treatments did not affect to total birth weight, the number of embryo, litter size, gestation period and sex ratio. The percentage of ewes pregnancy with the flushing treatment was 25% higher than the control. The flushing treatments were significantly effect on partus weight of ewes (p<0.05). Conclusion: It was concluded that three times flushing program at early, middle and late of gestation could improve the nutritional status and reproductive performance of ewes, such as fat intake, partus weight, improved percentage of pregnancy and type of birth, but did not affect to total birth weight, litter size, pregnant period and sex ratio.

“…The results of some basic studies performed on laboratory and farm animals and on cell cultures suggest the applicability of flaxseed for improvement of farm animal reproductive efficiency. As described above, feeding cows and goats with flaxseed can promote the development of their ovarian follicles 15 , 38 and increase the number and quality of their oocytes and embryos 14 , 15 , 24 , 47 .…”

This review describes the chemical composition of flaxseed (Linum usitatissimum) and its general health effects, as well as the currently available knowledge concerning its action on the female reproductive state, functions on the ovary and ovarian cells and reproductive hormones, as well as possible constituents and extra- and intracellular mediators mediating its effects on female reproductive processes. Flaxseed contains a number of biologically active molecules, which, acting through multiple signalling pathways, can determine numerous physiological, protective and therapeutic effects of flaxseed. The available publications demonstrate the action of flaxseed and its constituents on the female reproductive system – ovarian growth, follicle development, the resulting puberty and reproductive cycles, ovarian cell proliferation and apoptosis, oo- and embryogenesis, hormonal regulators of reproductive processes and their dysfunctions. These effects can be determined by flaxseed lignans, alpha-linolenic acid and their products. Their actions can be mediated by changes in general metabolism, metabolic and reproductive hormones, their binding proteins, receptors and several intracellular signalling pathways, including protein kinases, transcription factors regulating cell proliferation, apoptosis, angiogenesis and malignant transformation. Flaxseed and its active molecules are found potentially useful for improving farm animal reproductive efficiency and treatment of polycystic ovarian syndrome and ovarian cancer.
