    Long-Term Leachate Water Quality Trends from a Broiler-Litter-Amended Udult in a Karst Region (2014)
    Soil Science Society of America (SSSA)

    Publication Date: 2014-09-26
    Description: Application of broiler ( Gallus gallus ) litter (BL) to pasturelands in karst regions like the Ozark Highlands can potentially reduce water quality due to leaching of BL-derived nutrients and trace metals. The objective of this study was to determine long-term linear trends in drainage and soil leachate water quality under natural precipitation from a silt-loam soil amended annually with BL at three application rates (0 [control], 5.6 [low], and 11.2 [high] Mg BL ha –1 ]. Automated equilibrium tension lysimeters were used to continuously monitor and collect leachate from an undisturbed soil profile with a history of litter applications under forage management at a depth of 0.9 m for the 8-yr period from May 2003 through April 2011. Average annual flow-weighted mean (FWM) concentrations and loads of NH 4 –N, As, Mn, and Ni decreased linearly ( P 〈 0.05), while Cu and Se increased ( P 〈 0.05) linearly during the 8 yr. Nearly all water quality parameters measured were unaffected ( P 〉 0.05) by BL rate alone. Continued annual additions of BL linearly increased ( P 〈 0.05) the average annual FWM leachate Na concentrations relative to the unamended control. Results indicated that pasturelands with a history of BL application may continue to release BL-derived metals, such as As and Se, at concentrations harmful to health regardless of current management practice long after litter application has ceased. Land application of nutrient- and trace-metal-containing animal wastes in regions with underlying karst features needs to be carefully managed to minimize subsoil leaching losses.

    Notes: Eight multiparous Holstein–Friesian dairy cows in late lactation were used to investigate the potential of using perennial ryegrass with a high concentration of water-soluble carbohydrate (WSC) to increase the efficiency of milk production. After a pretreatment period on a common pasture, the cows were each given ad libitum access to one of two varieties of zero-grazed grass continuously for 3 weeks. Treatments were: high sugar (HS), an experimental perennial ryegrass variety bred to contain high concentrations of WSC; or control, a standard variety of perennial ryegrass (cv. AberElan) containing typical concentrations of WSC. The two grass varieties were matched in terms of heading date. All animals also received 4 kg day–1 standard dairy concentrate. Grass dry matter (DM) intake was not significantly different between treatments (11·6 vs. 10·7 kg DM day–1; s.e.d. 0·95 for HS and control diets respectively), although DM digestibility was higher on the HS diet (0·71 vs. 0·64 g g–1 DM; s.e.d. 0·23; P 〈 0·01) leading to higher digestible DM intakes for that diet. Milk yield from animals offered the HS diet was higher (15·3 vs. 12·6 kg day–1; s.e.d. 0·87; P 〈 0·05) and, although milk constituent concentrations were unaffected by treatment, milk protein yields were significantly increased on the HS diet. The partitioning of feed N was significantly affected by diet, with more N from the HS diet being used for milk production (0·30 vs. 0·23 g milk N g–1 feed N; s.e.d. 0·012; P 〈 0·01) and less being excreted in urine (0·25 vs. 0·35; s.e.d. 0·020; P 〈 0·01). In a separate experiment, using the same grasses harvested earlier in the season, the fractional rate of DM degradation, measured by in situ and gas production techniques, was higher for the HS grass than for the control. It is concluded that increased digestible DM intakes of the HS grass led to increased milk yields, whereas increased efficiency of utilization of the HS grass in the rumen resulted in the more efficient use of feed N for milk production and reduced N excretion.

    Notes: Four processing procedures were compared as methods of reducing warmed-over flavor (WOF) of pork chops during frozen storage for 84 days, These procedures were (1) oven-broiled chops, (2) chops from loins precooked with no additives, (3) chops from loins cured with 0.5% salt and 40 ppm NaNO2 and precooked, and (4) chops from loins cured with 2% salt and 120 ppm NaNO2 and precooked. Samples were evaluated by the TBA test, Warner-Bratzler shear, hydroxyproline assay and by sensory analysis after frozen storage at -18°C. Chops from the three precooked treatments were more tender than oven-broiled chops. Nitrite inhibited WOF development of precooked chops during frozen storage and 40 ppm nitrite was nearly as effective as 120 ppm.

    Notes: Thiamin (B-1) ascorbic acid (AA) and vitamin B-6 (B-6) were determined in pouched and canned green beans immediately after processing and after storage at 24–26°C or 38°C. AA and B-6 were also determined in pouched and canned cherries before and after storage at 24–26°C. There was significantly more B-1 and AA in drained pouched green beans, and more AA in drained pouched cherries than in canned ones. B-6 values in the solids of the pouched and canned products were not significantly different. These three vitamins were significantly reduced in drained pouched and canned green beans after storage at 38°C. B-6 was significantly reduced in the stored cherries. Compared to canned, the pouched products were brighter and firmer in texture.

    Notes: Heating treatments of boiling 20 min or autoclaving 5 min, 10 min, or 20 min, of soaked (25°C for 10 hr) soybeans, significantly influenced vitamin B-6, free folacin, trypsin inhibitor activity, water absorption, moisture content and blue, green and amber color values in the cooked soybeans. Analysis of covariance showed a relationship (P≤0.05) between water absorption after cooking with total folacin in cooked soybeans and water absorption after cooking with blue color values. Other relationships (P≤0.05) were observed in cooked soybeans between texture and total folacin, moisture and trypsin inhibitor activity, and trypsin inhibitor activity and free folacin.

    Notes: The effect of cooked wheat bran on fecal wet and dry weight, fecal nutrients and transit time was investigated in 10 men. The study was divided into three 18-day periods. Five subjects received the experimental diet supplemented with 15g (raw) of AACC wheat bran (B) served in a cooked form during the first period, no bran (NB) in the second, and B in the third. The remaining five subjects received, in order, NB, B, and NB. Fecal wet and dry weight were significantly higher (p 〈 0.05 and p 〈 0.01, respectively) when the subjects received B (172 ± 39 and 43 ± 3 g/day) than when they received NB (143 ± 34 and 36 ± 4). Fecal neutral detergent fiber (NDF) was significantly higher (p 〈 0.05) on B (8.3 ± 2.2 g/day) than on NB (5.1 ± 2.6 g/day). Fecal NDF correlated significantly (P 〈 0.05) with fecal wet and dry weights, and moisture. Bran induced significantly higher (p 〈 0.01) fecal losses of energy, nitrogen and ash, but these losses were too small to be important nutritionally.

    Notes: Fatty acid profiles and proximate composition were determined at seven carcass locations from 64 pigs. Fatty acid composition was not altered by PST treatment (P 〉 0.05). The more unsaturated outer layer of subcutaneous fat was present in a greater proportion in the PST-treated pigs. Adipose tissue fat content was decreased (P 〈 0.01), whereas percentage moisture and protein was increased (P 〈 0.01), by PST. Boneless ham characteristics did not differ among treatment groups (P 〈 0.05). Pepperoni from PST pigs dried more efficiently and was harder than control pepperoni. Bacon from PST pigs contained less fat and was softer than control bacon. Difference in texture of products, particularly bellies for bacon from PST-treated pigs, seemed to be a result of an altered proximate composition.

    Description / Table of Contents: Resumé La pulvérisation de suspensions aqueuses deNeoaplectana bibionis Bovien sur des cassissiers attaqués par la sésie du cassis,Synanthedon tipuliformis (Clerck) provoque jusqu'à 90% de mortalité des larves. Cette mortalité est influencée par la quantité de nématodes, le volume d'eau, l'âge du bois et l'époque d'application. Des nématodes migrent dans les nouvelles galeries, ce qui augmente le taux de parasitisme avec le temps. On n'a observé aucune phytotoxicité sur les touffes traitées. Le coût du traitement avec les nématodes peut être comparable à celui des insecticides sans aucun des problèmes associés à ceux-ci.
    Notes: Abstract Spraying of water suspensions ofNeoaplectana bibionis Bovien on established blackcurrant bushes infested with currant borer moth,Synanthedon tipuliformis (Clerck), resulted in up to 90% mortality of larvae. Mortality was influenced by dosage, water volume, age of wood and time of application. Some nematodes migrated to new tunnels resulting in an increase in parasitization with time. No phytotoxicity was observed on any of the treated bushes. The cost of nematode application may be comparable to that of insecticides without any of the associated problems.
