This study was conducted to investigate the effect of different levels of calcium salts of fatty acids (CSFA) on performance in Holstein calves. A total of sixteen 17 month of age male Holstein calves with average of (540 ± 5 Kg) weight were selected and were divided into four groups in order to the experimental complete randomized block design. The calves were fed by control groups with no fat protected and 2, 4 and 6 percentages of fat protected oils until 60 days. Feed intake, Body weight gain and feed conversion ratio were measured. The blood samples were taken to investigate the serum content of plasma protein, glucose, calcium, phosphorus, cholesterol, triglyceride, LDL and HDL. Additionally the fat and protein digestibility in each groups were measured. Data from this study showed that the highest FI and BW and the better FCR was related to the calves fed by 2 % fat protected supplement but there were no significant effects on calves performance between treatments. Feeding the fat protected supplementations lead to higher protein and fat digestibility none significantly. The higher use of calcium salts of fatty acids supplements lead to higher serum triglyceride, cholesterol, calcium and LDL significantly (P≤0.05). There were no significant differences between treatments about glucose, phosphorous and protein content in the calves were feed by different levels of calcium salts of fatty acids supplements. In conclusion we could demonstrated that using of different levels of calcium salts of fatty acids may have beneficial effects on performance and some blood biochemical in the male Holstein Calves.

Abstract Different levels and sources of NDF can modify the gastrointestinal microbiome. This study evaluated 18 Holstein calves housed in not-bedded suspended individual cages and fed one of three treatments: 22NDF - conventional starter containing 22% NDF (n = 7); 31NDF - starter with 31% NDF, replacing part of the corn by soybean hull (n = 6); and 22NDF+H - conventional starter with 22% NDF plus coast-cross hay ad libitum (n = 5). All animals received 4 L of milk replacer daily (24% CP; 18.5% fat; diluted to 12.5% solids), divided into two meals, being weaned at 8th week of age. After weaning, animals were housed in tropical shelters, fed with the respective solid diet and coast-cross hay ad libitum for all treatments. To evaluate the microbiome, ruminal fluid samples were collected using a modified Geishauser oral probe at weeks 2, 4, 6, 8 and 10, two hours after the morning feeding, and fecal samples were collected at birth (0) and at weeks 1, 2, 4, 8 and 10. The microbial community was determined by sequencing V3 and V4 region amplicons of the 16S rRNA gene that was amplified by PCR and sequenced by the Illumina MiSeq platform. Ruminal microbiome had no differences in diversity for the effects of weeks, treatments or interaction of both factors (Table 1). In feces, the diversity indices and evenness were higher for 22NDF+H when compared to 22NDF, with no difference for 31NDF. All indices were significantly affected by calves age. At birth, calves had the greatest diversity and richness. Week 1 and 2 had less evenness and diversity. Bacteroidota, Firmicutes_A and Firmicutes_C were the most abundant phylum in rumen and feces. The supply of hay was only effective in modifying the fecal microbiome of dairy calves, suggesting a resilience in the ruminal microbiome.

AbstractObjective:To evaluate the safety of phosphatidylserine (PS) enriched with omega3 fatty acids, mainly eicosapentaenoic (PS-Omega3) in children with attention-deficit hyperactivity disorder (ADHD).Methods:Two hundred children diagnosed with ADHD were randomised to receive either PS-Omega3 (300 mg PS-Omega3/day) or placebo for 15 weeks. One hundred and fifty children continued into an open-label extension for an additional 15 weeks in which they all consumed PS-Omega3 (150 mg PS-Omega3/day). Standard blood biochemical and haematological safety parameters, blood pressure, heart rate, weight and height were evaluated. Adverse events and the Side Effect Rating Scale were also assessed.Results:One hundred and sixty-two participants completed the double-blind phase. No significant differences were noted between the two study groups in any of the safety parameters evaluated. One hundred and forty participants completed the open-label phase. At the end of this phase, no significant changes from baseline were observed in any of the studied parameters among participants who consumed PS-Omega3 for 30 weeks.Conclusions:Study results demonstrate that consumption of PS-Omega3 by children with ADHD, as indicated in a 30-week evaluation period, is safe and well tolerated, without any negative effect on body weight or growth.

Ruminal Ph

Feeding goats with calcium salts of fatty acids (CSFA) can supply ruminants with lipids, with minimal effects on ruminal fermentation and fiber digestibility. However, there is a shortage of information on the effect of CSFA on characteristics of rumen fermentation in grassland goats. Thus, the present study aimed to assess the addition of CSFA to concentrate on the parameters of rumen fermentation of grazing goats. Five rumen cannulated goats were distributed in a Latin square 5x5 design (treatments: 0%, 1.5%, 3.0%, 4.5% and 6.0% CSFA. The pH, ammonia N and volatile fatty acids (VFA) content were analyzed in the ruminal fluid at 0, 2, 4, 6 and 8 hours after concentrate supplementation. The pH and ammonia N concentration showed a linear effect with the addition of CSFA. There was no effect observed for the VFA molar concentration after grazing goats were fed with the experimental diet. In conclusion, further research is needed to investigate the addition of CSFA to goat diets because there is evidence that CSFA increases ruminal pH and decreases excess ruminal ammonia without changing the VFA concentration in the rumen fluid.

This experiment was conducted to determine the dietary n-3 fatty acid requirement for reproduction of broodstock zebrafish, Brachydanio rerio. Three isonitrogenous (39% crude protein) and isocaloric (3,260 kcal digestible energy/kg diet) practical diets, namely diets A, B, and C, with different levels of fatty acids were fed to zebrafish broodstock. The broodstock were cultivated in aquaria. Diet A contained low dosage of n-3 fatty acids (0.4%) and 2% n-6 fatty acids, while diets B and C contained 2% n-6 fatty acids, combined respectively with 1% and 1.5% n-3 fatty acids. Fish were fed ad satiation for 60 days using these diets. During feeding periode, gonade maturation stages were examined. The n-3 and n-6 fatty acids affected fecundity, fertilization rate, and hatching rate. On the other hand, fish fed on diets A, B, or C did not show any significance differences in the gonade somatic index and total Survival Rate (SR) of larvae produced. Fish fed on diet B produced the highest fecundity (616 eggs/g of fish), fertilization rate (94.6%), and hatching rate (93.8%). The total lipid content of eggs were significant, ranging from B (29.7%), C (23.7%), and A (16.1%). At a dosage of 2% n-6 fatty acids, zebrafish require 1% of dietary n-3 fatty acids in the diet for reproduction. Excess dosage of n-3 fatty acid in the diet adversely affected fecundity, fertilization rate, and hatching rate.
