“…An increase in serum ALP activity is correlated with bone disorders and may be due to Ca or NPP deficiency or an insufficient ratio of Ca to P in the diet [34,35]. The lack of serum P and ALP activity response to Ca and P deficient diets is not in agreement with the finding by Baradaran et al [36], who reported that feeding broiler chickens with low-NPP diets (1.5 and 2.3 g NPP/kg) reduced serum P concentrations than those fed a control diet (4 g NPP/kg) at 42 d post-hatch. Additionally, they reported a quadratic decrease in serum ALP activity due to increasing phytase supplementation.…”

The influence of a bacterial 6-phytase on growth performance, coefficient of apparent ileal digestibility (CAID) of nutrients, blood parameters, and bone mineralization in broilers was evaluated. A total of 630 one-day-old male broilers were allocated to 7 dietary treatments, including positive control (PC) diet containing dicalcium phosphate, the PC marginally reduced in available P (avP) by 0.1% and calcium (Ca) by 0.2% vs. PC (NC1) or moderately reduced by 0.15 and 0.3% vs. PC (NC2), respectively, and four further diets comprising the NC1 and NC2 supplemented with 500 or 1000 FTU/kg of phytase in starter and finisher phases. A constant Ca to avP ratio was maintained across all diets. The body weight gain (BWG) and feed per unit gain (FCR) of birds fed NC1 and NC2 diets supplemented with phytase (500 and 1000 U/kg) was equivalent to that of birds fed the PC diet at 35 days. Phytase supplementation in the NC1 diet linearly increased the CAID of nitrogen (N) (p < 0.01), phosphorus (P) (p < 0.01), and Ca (p < 0.05). Additionally, phytase reduced (p < 0.01) excreta P concentration by approximately 27%, improved (p < 0.001) toe ash, and tended to increase tibia ash (p = 0.08), comparable with the PC. In conclusion, the addition of bacterial 6-phytase dosed in the range of 500–1000 FTU/kg was effective in replacing 1.5 g/kg avP and 3 g/kg Ca in broilers fed pelleted diets, using bone quality, BWG, and FCR as outcome measures.

“…Fosfor penting untuk mineralisasi tulang dan kadar fosfor sangat mempengaruhi kadar fosfor pada tulang tibia (Baradaran et al, 2021) Rata-rata kadar fosfor tulang tibia ayam kampung super pada penelitian ini disajikan pada Tabel 2. Pemberian tepung umbi AC dalam pakan berpengaruh sangat nyata (P<0,01) terhadap kadar fosfor tulang tibia ayam kampung super.…”

“…Sementara itu jagung, dedak padi dan bungkil kacang kedelai memiliki kadar asam fitat yang lebih tinggi dari pada umbi AC yaitu 1,16; 6,90 dan 0,39%. Baradaran et al (2021) menyatakan bahwa pemberian fitase melepaskan ikatan fitat sehingga ketersediaan fosfor meningkat dan kadar fosfor pada tulang tibia juga meningkat. Kadar fosfor tulang tibia ayam kampung super pada penelitian ini yakni 4,18±0,03 hingga 5,36±0,73%, lebih rendah daripada penelitian Hidayat dan Sumiati (2014) pada ayam lokal sentul yang diberi pakan mengandung dedak padi dengan level tinggi dan disuplementasi dengan fitase mempunyai kadar fosfor tibia antara 6,87-7,32%…”

Penelitian ini bertujuan untuk mempelajari pengaruh penggunaan umbi make (Amorphophallus companulatus, AC) di dalam pakan terhadap panjang, bobott, kadar kalsium, dan kadar fosfor tulang tibia ayam kampung super. Materi yang digunakan adalah ayam kampung super berumur delapan hari yang berjumlah 140 ekor jenis kelamin jantan dan betina (campuran). Ayam dibagi secara acak menjadi empat kelompok perlakuan dan lima ulangan dengan tujuh ekor ayam per ulangan.. Keempat perlakuan yaitu P0 (pakan kontrol tanpa AC), P1 (pakan dengan 5% AC), P2 (pakan dengan 7,5% AC), P3 (pakan dengan 10% AC). Perlakuan dimulai sejak ayam berumur delapan hari hingga 42 hari. Parameter yang diukur adalah panjang, bobot tulang tibia, dan kadar kalsium, fosfor tibia. Pada hari ke 42, dua ekor ayam per ulangan dikorbankan nyawanya dan tulang tibia diambil, untuk diperoleh datanya. Data dianalisis dengan analisis ragam dan jika ada pengaruh yang signifikan maka dilanjutkan dengan uji jarak berganda Duncan pada taraf probabilitas 5%. Hasil penelitian menunjukkan bahwa pengimbuhan AC dalam pakan tidak berpengaruh nyata terhadap panjang dan bobot tibia, tetapi berpengaruh nyata (P<0,05) terhadap kandungan Ca dan P tulang tibia. Simpulan dari penelitian ini adalah pemberian AC hingga 10% dalam pakan tidak memberikan efek negatif terhadap bobot, panjang, kadar kalsium dan kadar fosfor tulang tibia ayam kampung super

“…Additionally, due to P loss concerns, recent studies which investigated the broiler's physiological adaptation to moderate dietary P reductions initiated at the early growth phase highlighted the bird's capacity to incorporate different intrinsic compensatory mechanisms to define nutrient efficiency with maturity ( Valable et al, 2018 ; Baradaran et al, 2021 ). Endogenous mechanisms observed include the synergy between endocrinal regulators (e.g., calcitriol), gene expression (e.g., SLC34A2 ), and the contribution of intrinsic organismal P reservoirs such as the bone.…”
