Within the context of maximizing the use of dietary phosphorus, a growing-finishing pig study was conducted to determine the optimal total dietary calcium (Ca) to digestible phosphorus (dP) ratio and to verify the possibility of mineral phosphate removal during the finishing period on growth performance and mineral status. The potential for replacing chemical and mechanical bone properties by dual energy X-ray absorptiometry (DXA) measures on non-dissected feet was also verified. Three Ca to dP ratios (2.2:1, 2.5:1 and 2.8:1) within two dP levels (P+, P–) were fed during 91 days to 84 pigs. The grower and finisher P+ diets contained 3.0 and 2.4 and P– diets contained 2.5 and 1.7 g dP/kg, respectively. Growth performance and blood serum mineral content were independent of treatments, except that 2.2:1 impaired finisher feed conversion ratio compared to 2.5:1 and 2.8:1. Urinary P concentration increased by 37% in 2.2:1 compared to 2.5:1 and 2.8:1. Maximal load on bone and DXA mineral density were reduced in 2.2:1 compared to 2.8:1. Bone ash and volumetric density were reduced in 2.2:1 and 2.5:1 compared to 2.8:1. Diet P– reduced bone ash, maximal load, volumetric density and DXA bone mineral content and density. No interaction was observed between Ca and dP level. Therefore, 2.2:1 was insufficient for an efficient metabolic use of P, 2.5:1 was sufficient to maximize growth performance and 2.8:1 further improved bone mineralization. Increasing dietary Ca did not impair bone zinc content. Diets P– without supplemented mineral phosphates during the finisher period resulted, per pig, in a decrease of its use by 65% and of the calculated P excretion by 41%, without impaired growth performance. Finally, DXA data responded to dietary treatments as did labor intensive chemical and mechanical bone properties.

AbstractA 35-day experiment was carried out to study the effects of acidified and alkalinized diets on zootechnical indices, tibial calcium and phosphorous retention, bone mineralization and liver enzymes activity using 250 Ross 308 male broiler chicks. Five treatments consisting of a control diet (CD), CD acidified using 10, 20 and 30 g/kg citric acid (CA) and CD alkalinized with Ca (OH)2 (8.9 g/kg in growth period and 8.6 g/kg in finisher period) were examined in 5 replicates of 10 birds each from day 7 up to day 42 of age. Inclusion of 30 g/kg CA significantly increased body weight, average daily gain (ADG), average daily feed intake (ADFI), feed efficiency, tibia ash, tibia Ca content, at day 42 of age (P<0.05). Serum alkaline phosphatase and lactate dehydrogenase activities were elevated in the birds fed with the 30 g/kg CA-treated diet at day 42 of age (P<0.05). Alkalinized diet significantly reduced ADFI, tibia ash, tibial P and Ca contents, bone breaking strength and plasma Ca concentration (P<0.05). It was concluded that the diet acidified with 30 g/kg CA promoted productive performance and tibia mineralization in broiler chicken. Alkalinized diet suppressed growth performance of the birds perhaps through disrupted mineral absorption and altered liver enzymes activity.

Abstrak Allah SWT memerintahkan manusia untuk mengkonsumsi makanan yang halal dan baik. Salah satu Bahan Tambahan Pangan yang perlu diperhatikan kehalalannya adalah gelatin. Gelatin yang beredar di Indonesia sebagian besar diperoleh dari impor yang kemungkinan besar berasal dari tulang atau kulit babi. Selain dari tulang babi, gelatin dapat diproduksi dari tulang hewan yang halal seperti sapi, ikan atau ayam. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman dalam larutan asam klorida (HCl) dan variasi konsetrasi HCl terhadap produksi gelatin halal dari tulang ayam broiler. Penelitian ini dilakukan dalam dua tahap. Tahap pertama, pembuatan gelatin dengan variasi lama perendaman 12, 24, 36 dan 48 jam dalam HCl 5 %. Tahap kedua pembuatan gelatin dengan variasi konsentrasi HCl 3, 4, 5, 6 dan 7 % dengan lama perendaman optimal dari tahap sebelumnya. Karakterisasi produk gelatin dilakukan parameter uji kualitas gelatin dengan menentukan kadar air, kadar abu, derajat keasaman (pH), kekuatan gel, dan stabilitas emulsi dan kadar protein.Hasil penelitian menunjukkan bahwa lama perendaman dengan HCl pada poduksi gelatin tulang ayam broiler menghasilkan rendemen 7,89-10,21 %. Lama perendaman terbaik adalah 12 jam dengan rendemen 10,21 %, kadar air 8,00 %, kadar abu 11,50 %, dan pH  3,00. Sedangkan konsentrasi terbaik adalah 6 % yang dengan rendemen 3,68 %, kadar air 11,78 %, kadar abu 1,52 %, pH 4,78, kekuatan gel 9,8 N, stabilitas emulsi 63,39 % dan kadar protein 75,31 %. Kata kunci: gelatin halal; HCl, lama perendaman; konsentrasi: tulang ayam broiler. ABSTRACT Gelatin in Indonesia is generally obtained from imported product containing bone or pig skin. On the other hand, gelatin can be produced from halal sources such as cattle, fish or chickens. This study aims to determine the effect of curing time and HCl concentration variationon halal gelatin production from broiler chicken bone. This research was conducted in two stages.In the first stage, gelatin production with variation of curing time (12, 24, 36 and 48 hours) and in the second stage, gelatin production with variation of HCl concentration (3, 4, 5, 6 and 7%). Parameters in gelatin characterization are yield, moisture content, ash content, protein content, pH, gel strength, and emulsion stability. The results showed that the highest yield in gelatin production was 10.21% in 12 hours of curing time. Water content, ash content, and pH of the gelatin were 8.00%, 11.50%, and 3.00, respectively. Production of gelatin based on acid concentration variation gave the highest yield (1.52%) at HCl 6%. The chicken bone gelatin was analyzedwater, ash, and protein content which were 11.78%, 1.52%, and 75.31%, serially. Other parameters of the gelatin were 4.78 of pH, 412.4 g bloom of gel strength, and 63.39% of emulsion stability. Keywords: halal gelatin; HCl, curing time; acid concentration, broiler chicken bone;
