The objective of this work was to identify alterations in the histomorphology of the cortical bone tissue of broilers submitted to growing and finisher rations formulated with five different sources of phosphorus: dicalcium phosphate, simple superphosphate, triple superphosphate, monoammonium phosphate and Araxá rock phosphate. Histological images had their components segmented, and were called regions of interest (ROI). Images were analyzed through developed algorithms, using the SCILAB mathematical environment. Eleven features were considered in order to obtain a complete description of the bone images: percentage of bone by area, ROI area, ROI perimeters, ROI elongation, ROI angle and their respective standard deviations, besides entropy of ROI angles and a texture-oriented measure (lacunarity). The substitution of dicalcium phosphate in growing and finisher rations for any other tested source of phosphorus caused significant changes on the hystomorphology of the cortical broilers bones, for example: diminution of bone percentage by area, increase of lacuna area and worse matrix homogeneity. Changes were more pronounced in the Araxá rock phosphate treatments, with the highest fluorine content, than in simple superphosphate, triple superphosphate and monoammonium phosphate treatments, which were similar.

Dicalcium phosphate accounts for 70% of the total costs of mineral mixtures in Brazil and studies have been made of the use of alternative supplementary phosphorus sources for ruminants (SILVA FILHO et al, 1992). The aim of this work was to evaluate monoammonium phosphate (MAP), triple superphosphate (TSP) and Tapira rock phosphate (TRP) as alternative P sources to the expensive dicalcium phosphate (DCP) by studying the kinetics of radiophosphorus (32P) in the blood of sheep given such supplements.

The objective of this study was to evaluate the effects of different sources of phosphorus on performance, organ weight and blood parameters of pigs. One hundred and twelve pigs with body weight 28.65±2.82kg were distributed into randomized blocks, in a 8 × 2 factorial scheme (eight sources of phosphorus × two sexes), with four repetitions for males and three for females, with two animals per pen. The pigs were fed diets containing: dicalcium phosphate (DCP); monodicalcium phosphate (MCP); triple superphosphate (TS); single superphosphate (SS), Catalão-rock phosphate (ROCK), mix of sources (MIX), phosphoric acid (PAc) or a diet without any supplemental source of phosphorus (CONT). At 60 and 90kg, all pigs were weighed and blood samples were collected to determine alkaline phosphatase activity (APA), calcium (Ca) and phosphorus (P) and one animal per pen was killed to weigh the liver and kidneys and evaluate carcass yield. The use of diet CONT reduced the weight gain and feed intake, worsened feed:gain ratio and increased the relative weight of the kidneys, APA and Ca, and decreased blood P. The sources DCP, MCP, TS and PAc reduced the APA and maintained the P and Ca in the blood constant. Phosphorus sources TS, SS, ROCK and MIX generate similar levels of APA in pigs from 30 to 90kg to the diet without inorganic source of phosphorus without affecting their performance.

This study aimed to evaluate the residual effect of phosphorus sources and application techniques in the intercropping of forages during off-season crops. The experimental design was randomized blocks in a 4 × 2 + 1 factorial, being four sources of phosphorus [Bayóvar Reactive Phosphate (BRP), Monoammonium Phosphate (MAP), Simple Superphosphate (SS) and Triple Superphosphate (TS)], two application techniques (broadcasting and on rows) and an additional without phosphorus. The experiment was conducted during the off-season crop. The residual effect of phosphorus fertilization increased the growth and the production of biomass of forage sorghum regarding broadcast SS and TS sources. The lowest P contents in the tissue of plants fertilized with SS and TS may be attributed to the diluting effect, as it achieved the highest production of biomass. The application of TS favored a greater dry matter production in Brachiaria brizantha cv. Piatã. At the depth 0.00-0.05 m, there was a higher P content with the application of BRP. However, the production of biomass was low, a factor that may be related to an overestimation of P bound to Ca by the Mehlich-1 extractor. Under cultivation conditions, broadcast SS and TS had a higher residual effect.

Defluorination of rock phosphate by heat treatment is an important method of producing phosphates suitable for animal feed. A variety of such products have been evaluated as phosphorus sources for ruminants, e.g. Beeson et al. (1945) recorded that a material produced at a low temperature (600°C) was unsatisfactory for steers, but Ammerman et al. (1957) indicated that a calcined calcium phosphate acidified with either sulphuric or phosphoric acids was fully as satisfactory as dicalcium phosphate for steers, but not for growing sheep. Wise, Wentworth & Smith (1961) and O'Donovan et al. (1965) recorded that defluorinated rock phosphates (produced by unspecified methods) were as useful as dicalcium phosphate for growing cattle. Arrington et al. (1963) have reported that 32P contained in reagent grade dicalcium phosphate was better retained by growing cattle than when present as a defluorinated rock phosphate.

The aim of the investigations was to compare the utilization of phosphorus from different sources: from dicalcium phosphate, monocalcium phosphate with and without phytase enzyme, at a reduced level of the phosphorus source mentioned. The investigation was conducted on the total of 440 fattening chickens of the Arbor Acres strain divided into 4 groups according to the phosphorus source: K-group (110 chickens-dicalcium phosphate 2%); O-I-group (110 chickens monocalcium phosphate 1.4 %); O-II-group (110 chickens-dicalcium phosphate 1% + 0.1% phytase) and O-III-group (110 chickens monocalcium-phosphate 0.7 % + 0.1 % phytase). The trial on the chickens nutrition lasted 42 days. Production traits, i.e. body weight and weight gain, were used as phosphorus utilization criteria in this paper. The study results showed that the highest production results (P<0.05) were obtained with the chickens fed 0.1 % phytase feed supplements at a reduced level of the mineral phosphorus source.

In three experiments with broiler-type chickens ten phosphate supplements were evaluated either singly or in combination. The biological values of monosodium phosphate, sodium tripolyphosphate and a deflurinated rock phosphate were higher than that of dicalcium phosphate, sterilized bone meal, monocalcium dihydrogen phosphate, triple superphosphate and mono-dicalcium phosphate which were intermediate; Christmas Island phosphate and Nauru Island phosphate had the lowest values. Chick performance was high when fed diets containing combinations of triple superphosphate, with either defluorinated rock phosphate, dicalcium phosphate, sterilized bone meal or mono-dicalcium phosphate. These mixtures of cheap and expensive sources of phosphorus are a potential method of lowering the costs of supplementing poultry diets with phosphorus.

SUMMARYA field experiment was made with sorghum hybrid CSH-1 during the rainy seasons of 1968 and 1969 on a sandy loam soil to study the influence of amounts and sources of phosphate fertilizer on phosphorus nutrition. Concentration of P in the crop and uptake increased with increasing amounts of phosphate and with increasing proportions of water-soluble P in triple superphosphate-dicalcium phosphate and triple superphosphate-rock phosphate mixtures. Relative effectiveness values were calculated from P uptake at harvest by a multiple regression method. For triple superphosphate, nitrophosphate (30% water soluble P), dicalcium phosphate and rock phosphate (from Jordan) the values were respectively, 100, 74, 61 and 22.

<p>Forty-nine male calves were allotted in a randomized design, being that initially were performed seven replicates per treatment. At the end of the experiment were slaughtered four animals per treatment. The treatments were designed as following: CONT: control diet; DC120: Dicalcium Phosphate 120:1 ratio P: F; MDCP60: Monodicalcium Phosphate 60:1 ratio P: F; DC30: Dicalcium Phosphate 30:1 ratio P: F; TSP30: Triple Superphosphate 30:1 ratio P: F; DC10: Dicalcium Phosphate 10:1 ratio P: F; PRC10: phosphate rock concentrate of 10:1 of relation P: F. Alkaline phosphatase (ALP) of animals who consumed PRC10 diet was greater than the ALP of animals that consumed TSP30, DC10 and DC120. This result was obtained with animals with 650 days of confinement. The ALP of the animals that consumed PRC10 was greater at 866 days than in the animals consuming TSP30 and DC120 diets. The ash content was greater in the DC10 diet and the diets CAR10 and DC120 achieved the lowest value. The fluorine content in bone was higher in diet DC10, while the diets DC120, PRC10 and MDCP60 obtained the lower values. The area of Haversian canals and the relation Havers/Osteon area were higher in the diet DC30 and the lowest value was encountered in DC10. The mottled teeth were more intensely observed in the treatments DC10 and PRC10. It was concluded that high fluorine content in the diet increases the deposition of fluorine in bones, which negatively affects in the histological parameters of teeth and bones of beef cattle.</p>

To evaluate non-conventional phosphorus sources, a group of 400 Nellore cows mantained under pasture received a mineral mixture with different P sources (group I: superphosphate - 500 ppm P; group II: superphosphate - 340 ppm P plus rock phosphate Patos 160 ppm P; group III: superphosphate 340 ppm P plus dicalcium phosphate 160 ppm P; group IV - dicalcium phosphate 500 ppm P). There were no differences in pregnancy rate, calving rate and calving interval. A fluorine deposition in bone was observed for the treatments with superphosphate and rock phosphate (66.92 ± 15.53; 69.97 ± 6.5 and 64.05 ± 3.35% respectively for group I, II and III). Superphosphate was almost as good dicalcium phosphate to provide phosphorus for grazing cows and there was a potentially significant economic advantage over dicalcium phosphate.

SUMMARYA field experiment was made during the rainy seasons of 1968 and 1969 on a sandy loam soil to study the response of Sorghum hybrid CSH–1 to phosphorus in relation to content of water-soluble phosphate in fertilizers. Triple superphosphate, dicalcium phosphate, rock phosphate (200-mesh), nitrophosphate and mixtures of triple superphosphate with dicalcium phosphate and rock phosphate in 3:1, 2:2 and 1:3 ratios were studied. The amounts of phosphorus applied were 30 and 60 kg P2O5/ha. Phosphorus application significantly affected dry matterproduced, plant height, days to 50% bloom, number of grains per ear, thousand-grain weight, stover and grain yield. Triple superphosphate and 3:1 triple superphosphate/dicalcium phosphate mixture were the most effective while rock phosphate and 1:3 triple superphosphate/rock phosphate mixture the least. Differences among sources were more marked in 1968 and at the higher amount i.e. 60 kg P2O5/ha. The response of sorghum to phosphorus was considerably lowered when the water solubility waa below 50% in triple superphosphate/dicalcium phosphate mixtures and below 75% in triple superphosphate/rock phosphate mixtures. Relative effectiveness was assessed by calculating ‘superphosphate equivalents’ and ‘multiple regressions’. Using superphosphate equivalents dicalcium phosphate, nitrophosphate and rock phosphates were 47–53%, 35–56% and 3–25%, respectively, as effective as triple superphosphate.
