13. Poultry Litter for the Production and Quality of Enterolobium contortisiliquum Vell. Seedlings
ABSTRACT The objective of this work was to determine the efficiency of poultry litter ratios added to the commercial substrate and to peat in the growth and quality of Enterolobium contortisiliquum seedlings. The design was completely randomized, with 10 replications, in a 2 × 5 factorial arrangement with two substrates (peat and commercial substrate) and

14. Forage production and mineral composition of cactus intercropped with legumes and fertilized with different sources of manure
RESUMO: Objetivou-se avaliar o potencial produtivo e a composição mineral da palma forrageira IPA-Sertânia (Nopalea cochenillifera Salm Dyck), em cultivo isolado e consorciada com leucena [Leucaena leucocephala (Lam.) de Wit.] ou gliricídia [Gliricidia sepium (Jacq.) Steud.], e adubada com as fontes de esterco bovino, ovino, caprino e cama de frango. O e

15. Organic Fertilizer for Production of Toona ciliata Seedlings
ABSTRACT This study evaluated the effect of different sources of organic fertilizer and their most appropriate proportions to produce Toona ciliata seedlings. Broiler litter and cattle manure were used as organic fertilizer at four proportions in the substrate (0, 15, 30, and 45%). A control treatment was adopted with 6 kg controlled-release fertilizers (m-

16. Contribution of Litter and Leaf Decomposition of Byrsonima gardneriana
ABSTRACT The litter in tropical ecosystems is one of the compartments responsible for the transference of nutrients to the soil, having great importance for the conservation and maintenance of biodiversity. Thus, this study aimed to quantify the contribution and stock of litter and the leaf decomposition rate of Gardneriana byrsonima A. Juss (murici) in two

17. Arginine improves nutritional quality of sow milk and piglet performance
ABSTRACT The objective of this study was to evaluate the effect of L-arginine supplementation in lactation diets on the productive and reproductive performance of pluriparous sows and their litters. Seventy-six sows of the same genetic line were assigned to four treatments in a completely randomized design with 19 replicates. The experimental unit was the so

18. Nutrient cycling between soil and leaf litter in the Cerrado (Brazilian savanna) on eutrophic and dystrophic Neosols
ABSTRACT We evaluated nutrient cycling by measuring leaf litter production and decomposition in the Brazilian savanna (cerrado sensu stricto) on eutrophic (calcareous) and dystrophic (arenitic) Neosols over the same spatiotemporal scale. We installed three transects in the Cerrado with plots in each Neosol type. Areas along the transects were randomly chosen

19. Evaluation of Aluminum Chloride As an Effective Short-Term Solution for Reducing Odor - Causing Volatile Fatty Acids in Duck Litter
ABSTRACT This study evaluated the effects of aluminum chloride (AlCl3) on pH and volatile fatty acid levels in duck litter over the course of a three-week experimental period. Ninety one-day-old Pekin ducks (45 males and 45 females) were distributed into three treatments with three replicates each (10 ducks per replicate) using a completely randomized design

20. Effect of Litter on Development and Severity of Foot-Pad Dermatitis and Behavior of Broiler Chickens
ABSTRACT This study was conducted to evaluate the impact of litter type and litter treatment with enzymatic-bacterial production incidence and severity of footpad dermatitis and consequently on behavior of broiler chickens. A total of 1,200 one day-old Ross 308 broilers were randomly allocated to 4 treatments with 4 replicates in 2 x 2 factorial design. The

21. ANAEROBIC DIGESTION STABILITY TEST BY SHEWHART CONTROL CHART
ABSTRACT The anaerobic digestion (AD) operation complexity raise the importance of stability testing to verify whether the operating conditions are under control and whether the process is working as required. The current method of verifying process stability is by a range of the ratio between volatile fatty acidity and total alkalinity (VFA/ TA) within whic

22. Mass Balance Applied to Brazilian Conventional Broiler Houses during One Production Cycle
ABSTRACT Brazil plays an important role in global poultry production as it is the world's largest chicken exporter and the third largest broiler producer. Despite the development achieved by the Brazilian broiler industry as a result of the integrated production system, many obstacles still need to be overcome, in particular, housing environment. In this reg

23. Evaluation of Dietary Glycerin Inclusion During Different Broiler Rearing Phases
ABSTRACT The objective of this study was to evaluate the effect of the dietary addition of different levels of glycerin on the performance, litter moisture, pododermatitis incidence, and carcass and parts yield of broilers. In total, 1,610 broilers were reared in 35 pens with 46 birds each. A completely randomized experimental design, with five treatments wi

24. Influence of Covering Reused Broiler Litter with Plastic Canvas on Litter Characteristics and Bacteriology and the Subsequent Immunity and Microbiology of Broilers
ABSTRACT In broiler production, the litter is reused for consecutives flocks, and it is treated during down time between flocks to reduce its microbial load. Although covering the litter with a plastic canvas is a common litter treatment in the field, there is little scientific information available on its efficacy. The aim of this study was to evaluate the
