“…No significant ( P > 0.05) difference was observed in terms of feed intake among the dietary treatments throughout the entire experimental period, thus the improvement of live weight gain may be due to the increase in absorption of nutrients and its digestibility as reflected by improved feed efficiency. The findings are in agreement with Abdulla et al () who reported broilers fed PO, soybean oil and linseed oil did not influenced the feed intake but affected the body weight gain.…”

The present study assessed the effect of feeding palm oil (PO), sunflower oil (SO) and their combination on performance, fat deposition, fatty acid composition and lipogenic gene expression of broilers reared for 42 days. A total of 144 1-day-old broilers (Cobb500) were randomly allotted into four treatment diets with each having six replicates of six chicks in each replicate following a completely randomized design. Live weight gain and feed efficiency was significantly (P < 0.05) higher in birds fed with a combination of oil sources compared to controls. Birds fed with the combination of oil and SO alone had higher carcass yield and lower abdominal fat. Higher (P < 0.05) concentrations of unsaturated fatty acids (UFA) and lower concentrations of palmitic acid and saturated fatty acid (SFA) was found in birds fed SO alone and combinations of SO and PO. Furthermore, the outcomes showed that birds fed diet supplemented with SO and the combination of SO and PO down-regulated gene expression of key hepatic lipogenic enzymes of fatty acids synthase (FAS), acetyl-CoA carboxylase (ACC) and stearoyl-CoA desaturase (SCD). These findings suggest that the diet containing the combination of 2% PO and 4% SO may reduce hepatic lipogenesis, as well as lower abdominal fat content of broilers.

“…In other studies, researchers found that the accumulation of energy and fat in chicken recipient lard was higher than those fed with sunflower oil (Sanz et al, 2000). In broiler chickens, Abdulla et al (2017) did not observe any effect of tested dietary energy sources on slaughter yield, breast and leg percentages from grill weight. In contrast to the results of this research, Poorghasemi et al (2013) showed no significant effect of dietary lipid source on relative weights of the liver, heart and gizzar d in broiler chickens.…”

An experiment was conducted to determine effects of different levels and sources of fats in diets on growth performance, carcass characteristics and immune response of turkeys during four periods (0-21, 22 to 42, 43 to 63 and 64 to 70 days of age). A completely randomized design with five treatments, six replicates and eight B.U.T.6 turkey chickens per replicate was used. Treatments included: Control diet, diet containing 2.5% of soybean oil, diet containing 2.5% fat supplement, diet containing 5% soybean oil, diet containing 5% fat supplement. The results showed that using 5% of soybean oil increased average daily gain of turkeys (89.04 g) throughout the experimental period (0-70 days) compared with the control group (81.11 g; p < 0.05). Treatments containing 2.5 and 5% soybean oil improved feed conversion ratio compared to control group (p < 0.05). Soybean oil at the levels of 2.5 and 5% was led to higher spleen and bursa percentages compared to other treatments, respectively (p < 0.05). The level and source of dietary fat had not significant effect on antibody titer against Newcastle virus vaccine on 42 and 70 days of age (p > 0.05). It can be concluded that supplementing diet with 5% soybean oil improved the performance of turkeys.

“…The Ca requirement in modern broilers has been recently reported ( Applegate et al., 2003 , Li et al., 2012 , Li et al., 2015 , Li et al., 2016 , Li et al., 2016 , Abdulla et al., 2017 , Kim et al., 2018b ). The heightened interest in dietary Ca-related studies is due to its effect on phytase efficacy.…”

Interactive effect of dietary calcium and phytase on broilers challenged with subclinical necrotic enteritis: 3. Serum calcium and phosphorus, and bone mineralization

Calcium is chelated by phytic acid and forms phytate-mineral complexes reducing Ca availability and the ability of phytase to hydrolyze phytate. An increased Ca concentration in the gut favors the activity of Clostridium perfringens ( C. perfringens ). Therefore, it was hypothesized that high dietary calcium with high dietary phytase would decrease serum Ca and P and bone mineralization during necrotic enteritis occurrence. A total of 768 one-day-old Ross 308 male chicks were randomly allocated to 8 treatments with 6 replicate pens, each housing 16 birds. A 2 × 2 × 2 factorial arrangement of treatments was applied: dietary Ca (0.6 or 1.0%), phytase (500 or 1,500 FTU/kg), and challenge (no or yes). Half of the birds (384) were challenged with Eimeria spp. on day 9 and C. perfringens strain EHE-NE18 on day 14 and 15. Blood was collected from 2 birds per pen to determine Ca, P, and parathyroid hormone in the serum. The middle toe, tibia, and femur were excised from 2 birds per pen on day 16 and 29 for determination of ash, breaking strength ( BS ), and mineral concentration. The challenge decreased ( P < 0.05) serum Ca + in birds regardless of dietary Ca level (day 16). There was a challenge × Ca interaction ( P < 0.05) for tibial BS (day 16), with challenge being more severe in birds fed high Ca than low Ca diets. A challenge × phytase interaction ( P < 0.05) was present for femur ash (day 16), with high phytase only increasing ash in challenged birds. The challenge decreased ( P < 0.05) the BS of femur and tibia at each time point. Birds fed high dietary Ca had lower tibial Mg ( P < 0.001), Fe ( P < 0.001), Na ( P < 0.001), and Zn ( P < 0.05) concentrations (day 29). Altogether, high dietary Ca and phytase improved bone mineralization showing that attention to Ca and P nutrition and phytase matrix values is warranted when high levels of phytase are used.
