“…In agreement with our findings, Fassani et al (2004) reported that birds fed with a diet of 30 ppm boron consumed 140 g less feed than the 0 ppm group while exhibiting better feed conversion and similar mortality rates. However, the specific depressive effect regarding dietary boron supplementation on the feed intake of broilers was barely occasioned with the dietary levels of 300 ppm or more (Rossi et al, 1993).…”

Three levels of boron (0, 30, 60 ppm) were supplemented in practical corn-soybean based starter and grower diets, containing either adequate or inadequate Ca or P. A total of 1,800, 1-day-old sexed broiler chicks were assigned to six dietary treatments and fed with the experimental diets for 42 days. Boron improved the overall feed conversion ratio, but increased body weight only at 21 days of age (p<0.01). Boron decreased feed intake in the case of feeding on a diet deficient in Ca and P, and tended to increase feed intake when birds received a diet adequate in Ca and P, signifying significant boron by Ca-P interaction (p<0.01). Mortality was not influenced by boron (p>0.05). Dietary Ca and P deprivation reduced body weight and feed consumption significantly, but did not influence the feed conversion ratio and mortality (p>0.05). Serum Ca level, ALP and ALT activities were not influenced either by dietary Ca and P deficiency or boron supplementation. Serum P content increased with respect to boron at 30 ppm. Bone breakage strength was not affected by dietary variables. Tibia ash, Ca and P were increased in response to the supplementation diet with 30 ppm boron, whereas 60 ppm showed no effect in most cases. Accordingly, the dietary boron supplementation of 30 ppm significantly decreased fecal Ca and P excretion, while there was a numerical decline in the 60 ppm boron as compared to the 0 ppm boron group. Data presented herein indicated that boron, either at the 30 ppm or 60 ppm supplementation level, was effective in conversion of feed to body weight, whereas only boron at 30 ppm contributed to the mineralization of bone thereby augmenting more Ca and P while excreting less through faeces.

“…Likewise, dietary boron supplementation did not improve mineral retention in soft tissues and bone, except for the boron concentration. Our results are in accord with several authors who reported no benefits in the bone ash and Ca concentration of broilers in response to boron supplementation of 20 to 150 mg/kg (Fassani et al, 2004;Çınar et al, 2015). However, others have reported significant increases in tibia Ca concentration (Armstrong et al, 2000;Kurtoğlu et al, 2005;Bozkurt et al, 2012).…”

“…Similarly, Fassani et al (2004) reported that chickens fed with a diet of 30 ppm boron consumed 140 g less feed than controls while exhibiting lower FCR and without compromising weight gain and livability. In contrast, Bozkurt et al (2012) reported that 30 and 60 ppm boron supplementation tended to increase feed intake.…”

Evaluation of the Boron and Phytase, Alone or in Combination, in Broiler Diets

et al. 2017

A total of 800 day-old broiler chicks were assigned to four test diets to assess the efficacy of phytase, fermented from Aspergillus niger, and boron, as boric acid, on the growth performance and mineral profile in chickens. The dietary treatments included the basal diet and the basal diet supplemented with boron (20 mg/kg), phytase (500 phytase units/kg diet), or a combination of boron and phytase. The following parameters were measured: growth performance indices, serum biochemicals, ash and the mineral profile of the tibia, breast muscle, liver and excreta. Boron decreased the overall feed conversion ratio by 1.9% (P＜0.05) but did not affect the body weight and feed consumption of chickens grown for 42 days (P＞0.05). The performance indices were not significantly influenced by dietary regimens for the first 21 days of the experiment (P＞0.05). The addition of boron alone and boron + phytase resulted in significant increases in the boron concentrations of serum, bone, breast muscle, liver and excreta (P＜ 0.001). The serum alanine aminotransferase activity of chicks fed phytase was higher (P＜0.05) than all other treatments. The ash content and mineral composition of the breast meat, liver and tibia did not respond to individual or combined dietary modifications (P＞0.05). The chickens administered a diet with boron excreted less Cathrough excreta. However, the ash content and Fe and Cu concentrations in the excreta increased in response to phytase supplementation (P＜0.05). In summary, supplementation with boron alone improved the feed conversion efficiency of broiler chickens fed diets containing adequate levels of nutrients. However, the combination of boron and phytase did not cause further improvements in broiler performance or the bioavailability of minerals.

“…On the other hand, dietary boron supplementation did not affect P concentrations in the tibia and femur. The increased bone ash content of the hens corresponds with that of some studies (Qin & Klandorf, 1991;Wilson & Ruszler, 1997;Rossi et al, 1993b;Kurtoğlu et al, 2005), but not in others (Wilson & Ruszler 1998;Fassani et al, 2004). Wilson & Ruszlar (1998) observed that the addition of 50, 100, 200 and 400 mg boron/kg to layer diets decreased bone Ca and P concentrations while Fassani et al (2005) observed no response in bone Ca concentration when 30, 60, 90, 120 and 150 mg boron/kg were added to a broiler diet.…”

In this study dietary boron at different doses (0, 25, 50, 100 and 200 mg/kg feed) was supplemented to layers from 4 to 64 weeks of age. There was no significant difference between treatments with respect of mortality, egg production, egg weight, egg mass and cracked eggs. Significant increases were observed in body weight as age rose. Body weight was not affected by dietary boron supplementation at 16 and 40 weeks of age. At 64 weeks of age boron additions of 50, 100 and 200 mg/kg to the diet resulted in significant lower body weights than that of the control group. Egg quality parameters; albumen height and Haugh units, were improved when 25 or 50 mg boron/kg diet was supplemented above the other treatments. Shape index, shell thickness, shell breaking strength were not affected by treatments, though 25 mg boron/kg diet tended to increase shell breaking strength. Tibia bone strength and phosphorus content in the tibia and femur were not affected by boron supplementation. Boron supplementation at 25 and 50 mg/kg significantly increased femur bone strength, and ash and calcium content of the tibia and femur bones. Concentration of boron in bone increased with the increase in dietary boron.
