Abstract Background Maternal nutrition during gestation affects fetal development, which has long-term programming effects on offspring postnatal growth performance. With a critical role in protein and lipid metabolism, essential fatty acids can influence the development of muscle and adipose tissue. The experiment investigated the effects of late gestation supplements (77 d prepartum), either rich in saturated and monounsaturated fatty acids (CON; 155 g/cow/d EnerGII) or polyunsaturated fatty acids (PUFA; 80 g/cow/d Strata and 80 g/cow/d Prequel), on cow performance and subsequent calf growth performance as well as mRNA expression in longissimus muscle (LM) and subcutaneous adipose tissue at birth and weaning. Results There was no difference (P ≥ 0.34) in cow body weight (BW) or body condition score from pre-supplementation through weaning. Relative concentrations of C18:3n-3 and C20:4n-6 decreased (P ≤ 0.05) to a greater extent from mid-supplementation to calving for PUFA compared with CON cows. Cow plasma C20:0, C20:5n-3, and C22:6n-3 were increased (P ≤ 0.01) in PUFA during supplementation period. At birth, PUFA steers had greater (P = 0.01) plasma C20:5n-3. No differences (P ≥ 0.33) were detected in steer birth BW or dam milk production, however, CON steers tended (P = 0.06) to have greater pre-weaning average daily gain and had greater (P = 0.05) weaning BW compared with PUFA. For mRNA expression in steers: MYH7 and C/EBPβ in LM increased (P ≤ 0.04) to a greater extent from birth to weaning for PUFA compared with CON; MYF5 in LM and C/EBPβ in adipose tissue tended (P ≤ 0.08) to decrease more from birth to weaning for CON compared with PUFA; SCD in PUFA adipose tissue tended (P = 0.08) to decrease to a greater extent from birth to weaning than CON. In addition, maternal PUFA supplementation tended (P = 0.08) to decrease MYOG mRNA expression in LM and decreased (P = 0.02) ZFP423 in adipose tissue during the pre-weaning stage. Conclusions Late gestation PUFA supplementation decreased pre-weaning growth performance of the subsequent steer progeny compared with CON supplementation, which could have been a result of downregulated mRNA expression of myogenic genes during pre-weaning period.

Cow plasma C20:0, C20:5n-3, and C22:6n-3 were increased (P ≤ 0.01) in PUFA during supplementation period. At birth, PUFA steers had greater (P = 0.01) plasma C20:5n-3. No differences (P ≥ 0.33) were detected in steer birth BW or dam milk production, however, CON steers tended (P = 0.06) to have greater pre-weaning average daily gain and had greater (P = 0.05) weaning BW compared to PUFA.

Abstract Background Maternal nutrition during gestation affects fetal development, which has long-term programming effects on offspring postnatal growth performance. However, limited research is available for fetal programming effects of fatty acid supplementation on beef cattle. With a critical role in protein and lipid metabolism, essential fatty acids can influence the development of muscle and adipose tissue. The experiment investigated the effects of late gestation supplements, either rich in saturated and monounsaturated fatty acids (CON) or polyunsaturated fatty acids (PUFA), on cow performance and subsequent calf growth performance as well as gene expression in longissimus muscle (LM) and subcutaneous adipose tissue. Results There was no difference (P ≥ 0.32) in cow body weight (BW) or body condition score from pre-supplementation through weaning. There were treatment × time interactions (P ≤ 0.05) for plasma C18:3 and C20:4 concentrations, in which C18:3 and C20:4 of both CON and PUFA cows were greater at mid-supplementation than those at calving, while CON cows at birth had the intermediate concentrations. Cow plasma C20:0, C20:5, and C22:6 were increased (P ≤ 0.01) in PUFA. At birth, PUFA steers had greater (P = 0.01) plasma C20:5 and lower (P < 0.01) C18:2 and C18:1. No birth BW or milk production differences were detected (P ≥ 0.45), while CON steers had greater (P = 0.05) weaning BW and tended (P = 0.06) to have greater pre-weaning average daily gain compared to PUFA. There were treatment × time interactions (P ≤ 0.02) for MYH7 and C/EBPβ expressions in LM; expression of MYH7 was greatest in CON at birth, while C/EBPβ was greatest in PUFA steers at weaning. There tended (P = 0.06) to be a treatment × time effect for MYF5, in which expression was the greatest in CON steers at birth. Maternal supplementation of PUFA tended (P ≤ 0.10) to decrease MYOG expression in LM and ZFP423 expression in adipose tissue during the pre-weaning stage. Conclusions Late gestation PUFA supplementation decreased pre-weaning growth performance of the subsequent steer progeny compared to CON supplementation, which could have been a result of downregulated expression of myogenic genes during pre-weaning period.

Abstract Objectives were to investigate the effects of late-gestation supplementation of Ca salts of fatty acids to beef cows on cow performance and offspring pre-weaning growth performance. One hundred and ninety fall-calving, Angus Simmental cows were ranked by BW, BCS, and age. Cows were randomly assigned into 12 endophyte-infected, tall fescue pastures (4 pastures/treatment; 15–16 cows/pasture). Cows were fed an isocaloric supplement with soybean hulls mixed with: whole-shelled corn (CON), 155 g/cow/d of EnerGII (SFA/MUFA), or 40 g/cow/d of Strata 120 g/cow/d of Prequel (PUFA) during the last 83 4.9 d of gestation. Cow BW and BCS were measured at the initial, middle point, and end of supplementation, as well as at breeding and weaning. Milk yield was evaluated by weigh-suckle-weigh technique at 675.0 d postpartum. Steers were weaned at 174 5.0 d of age. Growth performance, milk, and blood parameters were analyzed with MIXED and reproductive data were analyzed with GLIMMIX procedures of SAS. The BW and BCS of the cows were not different (P 0.19) from trial initiation through weaning. Birth BW of the steers was not different (P = 0.62). The AI or overall pregnancy rates were not different (P 0.88). There was no difference (P 0.12) in milk yield or components. However, C15:0 and total n-3 fatty acids in milk from dams supplemented with PUFA was greater (P 0.05) than CON, while SFA/MUFA was intermediate and not different than the others. There was no difference (P = 0.83) for weaning BW of the steers. In conclusion, late-gestation supplementation of Ca salts of PUFA had no effect on cow BW, BCS, or milk yield, but increased total n-3 fatty acids in milk. Neither birth BW nor weaning BW of steers were affected by maternal fatty acid supplementation.

The objective was to investigate the effects of feeding late gestational beef cows supplements differing in fatty acid profile on steer progeny finishing phase growth performance, carcass characteristics, and relative mRNA expression of myogenic and adipogenic genes. Seventy Angus-cross steers (initial body weight [BW] 273 ± 34 kg) born from dams supplemented with either 155 g DM/d EnerGII (CON, rich in palmitic and oleic acids) or 80 g DM/d Strata + 80 g DM/d Prequel (PUFA, rich in linoleic acid, eicosapentaenoic acid, and docosahexaenoic acid) for the last 77 ± 6 d prepartum were used. Longissimus muscle and subcutaneous adipose biopsies were collected to evaluate relative mRNA expression of genes related to myogenesis and adipogenesis. Steers were slaughtered at 423 ± 6 d of age. No treatment × time interaction or treatment effect (p ≥ 0.21) was detected for steer finishing phase BW, while steers from PUFA supplemented dams tended (p = 0.06) to have a greater gain to feed ratio (G:F). Neither carcass characteristics nor relative mRNA expression was different (p ≥ 0.11). In conclusion, late gestation PUFA supplementation tended to increase steer progeny finishing phase G:F, but had no effects on finishing phase BW, carcass characteristics, or relative mRNA expression during the finishing phase.

Abstract Polyunsaturated fatty acids supplementation in late gestation change offspring metabolism; however, their effect is not well known on early gestation in ewes. The objectives of this study were to determine the effect of dietary supplementation with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in pregnant ewes on the concentration of EPA and DHA on fetal liver (FL) and fetal central nervous system (FCNS), and to evaluate the effect of the supplementation with EPA+ DHA on mRNA expression of genes associated with transport and metabolism of fatty acids (FA) in FL and placenta (caruncles and cotyledons). Twelve ewes (4 pens, three per pen) were blocked by pregnancy day. The ewes were assigned during the first 45 d of gestation to diet with an addition of 1.5% (dry matter bases) monounsaturated FA (MUFA) or EPA+DHA. A C-section was conducted at d 45 of gestation to collect FL, FCNS, caruncle and cotyledon. Data were analyzed using a mixed procedure (SAS). For the placenta mRNA concentration, a 2x2 factorial was used considering caruncle and cotyledon as the second main factor. Isomers of C18:1 (t6,8 and t12) increase (P < 0.05) in FL and FCNS with MUFA supplementation, fatty acids C20:3 (n-6), C20:3 (n-3), C22:1, C22:5 and C22:6 increase (P < 0.05) in FL and FCNS with EPA+DHA supplementation. In FL there was a tendency to increase for mRNA expression of FATP-1 (P = 0.10) with EPA+DHA supplementation, while mRNA concentration for LPL was greater (P = 0.02) for MUFA supplementation. In placenta DNMT3b and FFAR-4 showed a significant FA x tissue interaction (P < 0.05). These results suggest that FA supplementation during early gestation alters the FA profile in FL and FCNS and changed mRNA concentration of genes involved in the transport of FA and cell metabolism.

AbstractAngiopoietin-like protein 4 (Angptl4) is thought to cause an increase in serum triglyceride levels. In the present study, we elucidated Angptl4 expression in the mouse models of type 1 and type 2 diabetes mellitus, and investigated the possible mechanisms involved.Type 1 diabetes was induced in C57BL/6 J mice by treating them with streptozotocin (STZ). Type 2 diabetes was induced by feeding the mice a high-fat diet (HFD) for 18 weeks.The levels of Angptl4 mRNA expression in liver, white adipose tissue (WAT), and brown adipose tissue (BAT) were found to increase in the STZ diabetic mice relative to control mice. This effect was attenuated by insulin administration. In the HFD diabetic mice, the Angptl4 mRNA expression levels were increased in liver, WAT, and BAT. Treatment with metformin for 4 weeks attenuated the increased levels of Angptl4 mRNA. Fatty acids (FAs) such as palmitate and linoleate induced Angptl4 mRNA expression in H4IIE hepatoma cells and 3T3-L1 adipocytes. Treatment with insulin but not metformin attenuated FA-induced Angptl4 mRNA expression in H4IIE. Both insulin and metformin did not influence the effect of FAs in 3T3-L1 cells.These observations demonstrated that Angptl4 mRNA expression was increased through the elevated free FAs in diabetic mice.
