This study aimed to evaluate the effects of using different lipid sources in diets for dairy cows during the transition period and early lactation on productive performance and physiological parameters in Holstein cows. The cows were fed with the following diets: 1) control; 2) Refined soybean oil; 3) Calcium salts of unsaturated fatty acids (Megalac-E). Diets were formulated to meet the nutritional requirements of cows during the pre-partum and postpartum period. The experimental diets affected the dry matter intake, body weight, body condition score, and energy balance in the postpartum period. The experimental diets did not affect the biochemical parameters in serum: glucose, total protein, albumin, urea, serum urea nitrogen, total cholesterol, HDL-cholesterol, non-esterified fatty acids, β-hydroxybutyrate, aspartate aminotransferase, γ-glutamyl transferase, alkaline phosphatase, also not being observed differences between the contrasts analyzed. The lipid sources soybean oil and calcium salts not directly influence the plasmatic physiological parameters of dairy cows in the period transition. But, fat supplementation in the transition period resulted in a better metabolic status and productive performance, mainly improving energy balance post-partum

Cows were fed whole flaxseed or calcium salts of soybean oil as a fat source. Cows fed flaxseed had lower (P < 0.01) milk yield and higher (P < 0.01) percentages of fat and protein than cows fed calcium salts. Feeding whole flaxseed and calcium salts of soybean oil increased, respectively, the concentrations of alpha-linolenic acid and conjugated linoleic acid in milk. Key words: Flaxseed, fatty acids, fat supplement

Background: In order to reduce the effects of a negative energy balance, some measures have been taken into account in nutritional management during the transition period. The use of yeast, has been a good alternative used to improve the rumen metabolism and helping the adjustment of the microbiotato the new diet. The aim of the study was to evaluate the effects of supplementing a combination of yeast culture and hydrolyzed yeast on the metabolism of dairy cows during the transition period.Materials, Methods & Results: The experiment was conducted in a semi-extensive system, using 20 Holstein cows, divided equally into a control group (CG) and a supplemented group (SG). The SG received 28 g/animal/day of a combination of yeast culture and hydrolyzed yeast from 20 ± 2 days pre-calving until early lactation (18 ± 3 days). Serum concentrations of non-esterified fatty acids (NEFA), albumin and urea were determined at calving, and for three time points during the early postpartum period and three time points during the early lactation period. Regarding energy metabolism, prepartum concentrations of NEFA were higher than the physiological standard in both groups. However, NEFA, albumin and urea decreased during the early postpartum period in the supplemented animals and could be attributed to the yeast in enhancing ruminal microorganisms’ cellulolytic capacity, increasing fibre digestibility and starch utilization.Discussion: The increased concentration of non-esterified fatty acids (NEFA) due to the mobilization of fat deposits that happens in the transition period, especially in the postpartum period reflects the cow’s adaptation to the negative energy balance (NEB). The lower concentrations of NEFA observed in the present study could be attributed to the effect of the yeast in enhancing the ruminal microorganisms’ cellulolytic capacity. The control cows had a BCS within the recommended range while the supplemented group had it close to the minimal limit proposed for this period. Thus, supplemented cows lost less BCS during the early postpartum period, had a lower BCS loss during the experimental period and had lower NEFA concentration that the CG. It was possible to observe a difference in serum albumin and urea between treatments only in the postpartum period. Besides showing no significant effect in BCS on prepartum period, control cows had a BCS within the recommended range while the supplemented group had it close to the minimal limit proposed for this period. Cows with high BCS prepartum had higher plasma NEFA before and after calving. It can be observed in the present study in both groups. However, a positive effect in prevent subclinical disorders might be attributed to YC, since the SG showed low NEFA plasma levels compared to the CG.  Thus, supplemented cows lost less BCS during the early postpartum period, had a lower BCS loss during the experimental period and had lower NEFA concentration that the CG. There is a negative correlation between BCS and NEFA in the early postpartum period and this information explains the results observed in the present study where BCS declines in the SG are followed by a NEFA increase. This is not so marked in the CG, indicating that SG supplementation can act by improving digestibility. Yeast supplementation promotes higher output energy, enhancing postpartum performance in dairy cows. Yeast supplementation showed benefits in early lactation compared to the prepartum and early postpartum periods, suggesting that supplementation has to have an adaptation period to be effective in protein synthesis. In conclusion, supplementation with a combination of yeast culture and hydrolyzed yeast to cows during the transition period can positively influence the energy and protein metabolism, reducing the collateral effects of negative energy balance.

Solving reproductive problems of postpartum dairy cows has become one of the main targets of the scientific community even though the advances in this field are partial in most of the conducted research. There is a need to approach the problem with a multidisciplinary strategy that simultaneously includes nutritional and reproductive issues. Increasing the availability of glucogenic and lipogenic nutrients during the transition period has been hypothesised to improve energy balance and to decrease the incidence and severity of metabolic and reproductive disorders in early lactation. Based on the considerations mentioned above, the objective of this study was to compare the effects of a glucogenic or a lipogenic diet on blood metabolites and follicular dynamics in primiparous dairy cows during the transition period. Forty primiparous dairy cows received a lipogenic or glucogenic supplement during the transition period and were randomly assigned to 1 of 4 treatments [control; calcium salts of soybean fatty acids (CaS), Megalac-E; toasted soybean; and propylene glycol]. Diets were isocaloric and isoproteic. Blood samples were taken from each animal 10 and 5 days before the expected calving date and at days 7, 14, 21, 28, 35, and 42 postpartum. Ultrasound scanning was performed in all cows on Monday, Wednesday, and Friday up to day 45 postpartum. Follicles registered during ultrasound examination were classified in 4 categories: class I (3–5 mm), class II (6–9 mm), class III (10–15 mm), and class IV (>15 mm). Data analysis was performed using PROC GLM (SAS, 6.12, SAS Institute Inc., Cary, NC, USA, 1995). Metabolites and ovarian activity were analysed using a split-plot design. Pairwise comparisons of individual means were carried out using the Scott Knott and Duncan test. Values of P < 0.05 were considered statistically significant. Insulin and glucose concentrations were higher in the CaS group when compared with other treatments (P < 0.05). The lowest insulin and glucose concentrations were observed on cows supplemented with propylene glycol. Nonesterified fatty acid concentrations (NEFA) were lower for all treatments compared with the control group (P < 0.05). The most efficient follicular growth pattern during the postpartum period was observed in the CaS group, which was characterised by a reduction in the number of class I and II follicles and an increase in class III and IV throughout the trial. In general, smaller follicles go through recruitment and selection processes to bigger follicles and these follicles probably remain stable due to the fact that this particular follicular class represents a transitory phase in which there are always follicles going under the processes of selection and dominance. Overall, results suggest that calcium salts of soybean fatty acids reduced the dramatic metabolic and endocrine changes of primiparous dairy cows during transition period, which could be associated with better reproductive performance.

Abstract This experiment evaluated the effects of feeding whole cottonseed (WC) and/or calcium salts of fatty acids (CSFA) on dry matter intake (DMI), performance, and carcass characteristics of Bos indicus animals receiving a high-concentrate diet during the finishing phase. On day 0, 96 Nellore bulls were blocked according to initial shrunk body weight (BW; 302 ± 26.7 kg) into group pens (4 animals/pen) and, within blocks, pens were randomly assigned to receive: 1) 15% of WC and 2% of CSFA [dry matter (DM) basis] of palm, cottonseed, and soybean oil (15WC; n = 6), 2) 10% of WC and 3% of CSFA (DM basis) of palm, cottonseed, and soybean oil (10WC; n = 6), 3) 5% of WC and 4% of CSFA (DM basis) of palm, cottonseed, and soybean oil (5WC; n = 6), and 4) 0% of WC and 5% of CSFA (DM basis) of palm, cottonseed, and soybean oil (0WC; n = 6). Diets were formulated to be isocaloric, isonitrogenous, and isolipidic. Experimental period lasted 108 days, whereas dry matter intake (DMI) was evaluated daily and blood samples and carcass measurements were obtained on days 0, 55, and 108 of the study. Upon slaughter on day 109, steaks were collected for determination of the chemical and fatty acid (FA) profile of the meat. No treatment effects (P ≥ 0.35) were observed on DMI, performance, average daily gain (ADG), carcass ultrasound measurements, and chemical variables of the steak. Nonetheless, including WC into the diets increased C12:0, C16:0, C16:1 trans-9, C17:0, C18:0, C18:1 cis-9, C18:2 cis-9,cis-12, C18:3 cis-9,cis-12,cis-15, saturated, and unsaturated FA intake (P &lt; 0.01). Moreover, adding WC increased DMI fluctuation and feed efficiency (P = 0.03), but decreased marbling (P ≤ 0.03). A treatment × day interaction was observed (P &lt; 0.01) for serum leptin concentration, as 10WC animals had greater leptin concentration on d 103 vs. other treatments (P &lt; 0.01). Regarding steak FA profile, WC addition into the diet increased C18:2 cis-7,trans-9 and C18:3 cis-9,cis-12,cis-15 (P &lt; 0.001), whereas saturated FA was quadratically affected (P = 0.02) and unsaturated FA was reduced for 15WC (P &lt; 0.04). In summary, increasing levels of CSFA into isolipidic finishing diets containing WC did not negatively impact feedlot performance, but reduced feed efficiency and increased marbling scores of Bos indicus bulls, demonstrating its feasibility as a technology to improve carcass traits of low-marbling animals.

Severe negative energy balance (NEB) in the postpartum period of dairy cows may be associated with declining fertility but the mechanisms by which nutrition influences reproduction are complex, poorly understood and confounded by lactation. Hence, both chronic and acute nutritional restriction of beef heifers have been used as models to examine the effects of NEB on ovarian and endocrine responses in the absence of lactation. Plasma IGF-I concentrations gradually decreased until the onset of anoestrus (Stagg et al., 1999) but concentrations may be confounded with stage of the oestrous cycle, especially around ovulation (Mackey et al., 2000). Therefore, the aim of this study was to examine the effect of nutritional restriction on periovulatory oestradiol (E2) and IGF-I concentrations.
