Effect of Arginine Supplementation on Growth Performance and Immunity of Broilers: A Review

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.

Influence of Thermally Oxidized Vegetable Oil and Animal Fats on Growth Performance, Nutrient Digestibility, Carcass Parameters and Meat Quality of Broilers

“…All nutrients in the experimental diets were formulated according to the nutrient requirement suggested by NRC (1994), except for ME, which was 100 kcal/kg less than recommendations for LE diets. All diets were formulated on digestible amino acids (AA) basis keeping lysine as reference AA as described in a recent study (Abdullah et al 2019). Feed was offered in pellet form.…”

Effects of Bile Acids and Lipase Supplementation in Low-Energy Diets on Growth Performance, Fat Digestibility and Meat Quality in Broiler Chickens

et al. 2020

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.

“…The ingredients used in the diet formulation were taken from the Brazilian table for Poultry and Swine. All diets were formulated on digestible amino acids basis keeping lysine as the reference amino acid as described in a recent study (Abdullah et al 2019). For the experiment, a total of 24 pens were used with the dimensions of 9.2 × 4.2 × 2.5 cubic feet per pen.…”

Emulsifier Supplementation Response in Ross 308 Broilers at 1-10 Days

et al. 2020

The study was conducted to check the effect of emulsifier supplementation on growth performance of broiler birds on starter phase, from days 1 to 10. In the current study, a total of twelve hundred twenty-four Ross 308 broiler one day old chicks were used. Ross 308 broiler chicks were divided into two groups in such a way that each group had12 replicates, and each replicate had 51 birds. The duration of the current trial was of 10 days. Chicks were fed experimental diets with or without emulsifier supplementation. Daily feed intake, body weight, feed conversion ratio and nutrient digestibility were recorded. Mortality was recorded on a daily basis, and feed intake was also corrected for mortality. Data collected from the experiment was interpreted by using analysis of variance method using SPSSTM under Completely Randomized Design. Results showed that emulsifier supplementation improved (p<0.05) feed intake in broiler birds on the 2nd, 6 th , 7 th and 9 th days of the starter phase. Furthermore, emulsifier supplementation (p<0.05) affected the body weight on the 3 rd and 10 th day of the trial. Emulsifier supplementation also affected (p<0.05) feed conversion ratio on the 10 th day of the trial. However, nutrient digestibility was not affected by the supplementation of emulsifier in the diet of broiler chicks. Results showed that emulsifier supplementation should be started on day 10.
