“…Before chemical analysis, excreta samples were dried at 57 °C for 72 h, after which they were ground to pass through a one-mm screen. Feed and excreta content of moisture and fat was determined according to the methods of the Association of Official Analytical Chemists (AOAC, 2006) as decribed in literature (Muhammad et al 2016;Niu et al 2017;Xia et al 2018). Fat contents were determined by Soxhlet apparatus.…”

The aim of this study was to investigate the effect of bile acids and lipase supplementation in low energy (LE) diets on growth, fat digestibility, serum lipid profile and meat quality of broilers. Seven hundred one-day-old broiler chicks were divided into 5 dietary treatments with five replicates of 28 birds each. The five treatments were: i) high energy diet (HE; metabolizable energy (ME) = 3,000 and 3,170 kcal/kg for starter and finisher diet), ii) low energy diet (LE; ME = 2,900 and 3,070 kcal/kg for starter and finisher diet), iii) LE diet supplemented with 300 g/ton bile acids (LEB), iv) LE diet supplemented with 180 g/ton lipase (LEL), v) LE diet supplemented both with bile acids (300 g/ton) and lipase (180 g/ton). The experiment lasted 35 days having starter phase from days 1-21 and finisher phase from days 22-35. Dietary inclusion of both bile acids and lipase in LE diet had no effect (p>0.05) on body weight (BW) gain and feed intake. High energy diet reduced feed intake and BW gain during starter and overall period; however, during finisher phase BW gain was similar in all dietary treatments. Dietary energy level had no effect on feed conversion ratio. Fat digestibility (p>0.05) both in the starter and finisher phase was not affected by the dietary treatments. Concentration of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides were not affected by the dietary treatments (p>0.05). Meat quality of breast and thigh muscle was unaffected due to the dietary treatments (p>0.05). It is concluded that the supplementation of bile acids alone or in combination with lipase in low-energy diets did not improve broiler performance, fat digestibility, serum lipid profile and meat quality.

“…On day 35, ten birds were randomly selected from each treatment (2 birds per pen) for blood collection. Serum lipid profile was determined following the procedure of previous studies (Chen et al 2019;He et al 2018;Su et al 2013). Blood samples were then centrifuged at 3,000×g for 15 min and serum was separated.…”

The current study was planned to investigate the influence of soy oil, oxidized soy oil, poultry oil single refined and poultry oil double refined on the performance of broilers chicken. A total of two hundred and forty, day-old broiler chicks were divided into 4 treatments in such a way that each treatment had six replicates and each replicate had ten chicks. The experimental treatments were separated with the usage of single refined poultry oil, double refined poultry oil, oxidized soy oil and soy oil in the diet of broilers. In both starter and overall periods average body weight was higher (p<0.05) for birds which were on a basal diet containing soy oil as compared to other diets. Similarly, feed intake was higher (p<0.05) for birds which were on a basal diet containing soy oil in the starter phase. In the overall phase, average body weight was less in oxidized oil as compared to other dietary treatments (p<0.05). Similarly, birds showed poor feed conversion ratio in the basal diet that contained oxidized oil (p<0.05) in the overall phase of the experiment. The birds showed better digestibility (p<0.05) for crude fat on a basal diet containing vegetable oil and double refined poultry oil as compared to other diets. Results showed no effects of experimental treatments on the meat quality and carcass parameters (p>0.05). Therefore, it can be concluded that poultry single refined and double refined oil could be a possible substitute for fresh soy oil for better performance as compared to oxidized soy oil.

“…Compared with the control group, elemental Mg supplementation decreased the relative abundance of the Prevotellace-ae_UCG-001 group, Ruminococcaceae_UCG-014 group, Mollicutes_RF9 group, and genus Bifidobacterium. The Prevotellaceae_UCG-001 group is a hemicellulose degrader (Thoetkiattikul et al, 2013;He et al, 2017). Members of the Ruminococcaceae_UCG-014 group can also be essential fiber degraders, as its abundance is positively associated with dietary NDF intake (Zhang and Wang, 2018).…”

Hydrogen is a key metabolite that connects microbial fermentation and methanogenesis in the rumen. This study was to investigate the effects of elevated H 2 produced by elemental Mg on rumen fermentation and methanogenesis in dairy cows. Four nonlactating Chinese Holstein dairy cows were employed for this experiment in a replicated crossover design. The 2 dietary treatments included a basal diet supplemented with Mg(OH) 2 (14.5 g/kg of feed dry matter) or elemental Mg (6.00 g/kg of feed dry matter). When compared with Mg(OH) 2 treatment, cows fed diet with elemental Mg had similar rumen Mg 2+ concentration, but higher rumen dissolved H 2 and methane concentrations at 2.5 h after morning feeding. Also, elemental Mg supplementation decreased feed digestibility, rumen volatile fatty acid concentration, and relative abundance of group Ruminococcaceae_UCG-014, genus Bifidobacterium, and group Mollicutes_RF9, increased acetate to propionate ratio, succinate concentration, and abundance of family Christensenellaceae. Elemental Mg supplementation increased enteric CH 4 emission, altered methanogen community with increased abundance of order Methanomassiliicoccales, 16S ribosomal RNA gene copies of methanogens, and order Methanobacteriales. In summary, the pulse of elevated dissolved H 2 after feeding produced by elemental Mg inhibited rumen fermentation and feed digestibility by decreasing the abundance of carbohydrate-degrading bacteria, promoted H 2 incorporation into succinate by increasing family Christensenellaceae and genus Bacteroidales_ BS11, and increased H 2 utilization for methanogenesis by favoring growth of methanogens.
