“…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).…”

“…Therefore, a daily intake of 50 μg boron per day by humans via consumption of 200 g chicken breast meat should not result in toxic levels of boron. The combined evidence indicates that boron can interact with the metabolism of some macro-minerals, such as Ca, P and Mg, and ALP, thereby modifying their concentrations in the serum of broiler chickens (Kurtoğlu et al, 2001(Kurtoğlu et al, , 2005Bozkurt et al, 2012). However, here, the serum biochemical constituents were not affected by supplemental boron (P＞ 0.05).…”

“…In contrast, Bozkurt et al (2012) reported that 30 and 60 ppm boron supplementation tended to increase feed intake. More research is needed to verify the assumption that chickens fed a diet with supplemental boron could fulfil their nutrient requirements on a lower feed intake and reach a similar body weight to those given a diet containing no boron.…”

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.

“…Because of this reason, the physiological role of boron has been widely studied. Appropriate amount of boron has a beneficial effect on the growth and development of the bone [11][12][13][14][15], the proliferation and differentiation of blood cells [16], and the functions of the brain [17], while high-level boron was harmful [18,19]. However, to our knowledge, so far, no study has evaluated the effects of boron on brain development.…”

The degree of brain development can be expressed by the levels of brain brain-derived neurotrophic factor (BDNF). BDNF plays an irreplaceable role in the process of neuronal development, protection, and restoration. The aim of the present study was to evaluate the effects of boric acid supplementation in water on the ostrich chick neuronal development. One-day-old healthy animals were supplemented with boron in drinking water at various concentrations, and the potential effects of boric acid on brain development were tested by a series of experiments. The histological changes in brain were observed by hematoxylin and eosin (HE) staining and Nissl staining. Expression of BDNF was analyzed by immunohistochemistry, quantitative real-time PCR (QRT-PCR), and enzyme linked immunosorbent assay (ELISA). Apoptosis was evaluated with Dutp-biotin nick end labeling (TUNEL) reaction, and caspase-3 was detected with QRT-PCR. The results were as follows: (1) under the light microscope, the neuron structure was well developed with abundance of neurites and intact cell morphology when animals were fed with less than 160 mg/L of boric acid (groups II, III, IV). Adversely, when boric acid doses were higher than 320 mg/L(groups V, VI), the high-dose boric acid neuron structure was damaged with less neurites, particularly at 640 mg/L; (2) the quantity of BDNF expression in groups II, III, and IV was increased while it was decreased in groups V and VI when compared with that in group I; (3) TUNEL reaction and the caspase-3 mRNA level showed that the amount of cell apoptosis in group II, group III, and group IV were decreased, but increased in group V and group VI significantly. These results indicated that appropriate supplementation of boric acid, especially at 160 mg/L, could promote ostrich chicks' brain development by promoting the BDNF expression and reducing cell apoptosis. Conversely, high dose of boric acid particularly in 640 mg/L would damage the neuron structure of ostrich chick brain by inhibiting the BDNF expression and increasing cell apoptosis. Taken together, the 160 mg/L boric acid supplementation may be the optimal dose for the brain development of ostrich chicks.

“…In our study, the serum P concentration was at its normal values except during calving in boron and control groups ( Table 2). We observed that serum P concentration was higher (P<0.05) in postpartum week 2 in group B than in group C. The data of the study on chickens show that boron supplementation to diets increased the serum P concentration (Kurtoğlu et al 2001, Bozkurt et al 2012, whereas another study on rabbits indicates that boron administration did not change the P concentration (Basoglu et al 2010).…”

Abstract. The aim of this study is to evaluate the effects of sodium borate on the concentrations of serum calcium (Ca), magnesium (Mg) and phosphorus (P) in dairy cattle in the peripartum period. In the study, 14 healthy Holstein cows in the periparturient period (four weeks before and three weeks after calving) were divided into two equal groups according to oral treatments with sodium borate (30 g/day, group B), while some cows from the group were not treated (group C). Blood samples were obtained weekly from the prepartum 4 weeks until postpartum 3 weeks. At calving, changes were observed for the concentrations of the serum Ca, Mg and P in B and C groups. Ca (p>0.05) and Mg (p<0.001) concentrations were higher in group B than group C at calving. During the postpartum periods serum Ca and Mg concentrations increased (p<0.05) in group B compared to group C. Serum P concentrations were not affected by boron. The results suggest that sodium borate may be useful for sustaining metabolic balance and perhaps in preventing metabolic disorders such as milk fever and hypomagnesemia in dairy cattle during the periparturient period.
