The study was conducted to determine the effect of feeding systems on fattening performance, slaughter, and carcass characteristics
of male Norduz kids. In the study, 20 male Norduz kids weaned at 2.5 months of age were divided into two groups after weaning.
The first group was reared under semi-intensive conditions (SI) on a mixture of pasture and concentrate, and the second group
was reared under extensive conditions (E) on pasture only. SI group had higher final weight (35.30 kg versus 32.81 kg), daily
weight gain (153.10 g versus 132.14 g), and warm carcass yield (44.84% versus 46.55%) compared to the E group although there
were no significant differences. Body organs, carcass parts, prime cuts, and chemical composition of the chop area did not
also differ in two groups significantly. As a conclusion, this study showed that semi-intensive feeding systems improved kid
fattening performance and carcass characteristics. 相似文献

Poultry manure (PM) has been traditionally applied to crops for decades as an organic fertilizer, because it is a good and balanced source of plant nutrients. Its effect on plant growth and yield has been widely investigated and is well known. However, there has been little effort to relate elemental compositions of the manure applied to their concentrations in the plants. The objective of this study was to examine the effects of PM on the growth, and essential and non-essential element composition of pepper (Capsicum annuum) leaves and also fruits. Pepper plants were grown in soil with 0, 10, 20, and 40 g kg?1 PM under greenhouse conditions. Concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), silicon (Si), aluminum (Al), iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), molybdenum (Mo), chloride (Cl), nickel (Ni), bromine (Br), rubidium (Rb), strontium (Sr), barium (Ba), lanthanum (La), and cerium (Ce) in leaves at the flowering stage and in fruits were determined by polarized energy dispersive X-ray fluorescence (PEDXRF). Poultry manure fertilization significantly improved pepper shoot growth and also fruit yield, and increased leaf and fruit P concentrations but not N, K, Mg, Si, Al, Ni, and Fe. Leaf Ca was significantly reduced by increased rate of PM application. Applied PM increased the concentrations of leaf and fruit Zn and Cl. Poultry manure applications had a positive effect on the concentrations of leaf Cu, and fruit Mn. The concentrations of Rb and Ce in fruits and Br in fruit and leaves were increased by PM treatments. Applied PM levels had no clear effect on the concentrations of Ba and La in pepper leaves. The leaf Ba was the highest with 10 g kg?1 PM, and leaf La was higher in 20 and 40 g kg?1 PM treatments than in the control. 相似文献

Exogenous estrogens used for therapeutic purposes or endogenous estrogen sources such as functional Sertoli cell or ovarian granulosa cell tumors may cause bone marrow toxicity in dogs. The condition is characterized by hematologic abnormalities including thrombocytopenia, anemia, and leukocytosis or leukopenia. Despite intensive therapy with blood or platelet-rich transfusions, broad-spectrum antibiotics, steroids, and bone marrow stimulants, prognosis is unfavorable. Due to the the risk of stimulating the development of uterine diseases and the potential for inducing aplastic anemia, estrogen use in dogs is best avoided where possible. This paper describes the causes of estrogen-induced myelotoxicity, the clinical presentation of the patients, the diagnosis, and the treatment options in the dog. 相似文献

The present study was designed to compare the responses in freshwater fish Oreochromis niloticus exposed to a synthetic pyrethroid, cypermethrin (CYP); an essential metal, copper (Cu); and a nonessential metal, lead (Pb).
Fish were exposed to 0.05 μg/l CYP, 0.05 mg/l Cu, and 0.05 mg/l Pb for 4 and 21 days, and the alterations in serum enzyme
activities, metabolite, and ion levels were determined. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)
activities increased in response to CYP, Cu, and Pb exposures at both exposure periods. While elevations in alkaline phosphatase
(ALP) and lactate dehydrogenase (LDH) activities and in cholesterol level were observed in pesticide-exposed fish at 4 and
21 days, they increased in Cu- and Pb-exposed fish at 21 days. Although metal-exposed fish showed increases in cortisol and
glucose levels at 4 days followed by a return to control levels at the end of the exposure period, their levels elevated in
pesticide-exposed fish at both exposure periods. Total protein levels decreased in Pb- and pesticide-exposed fish at 21 days.
Na+ and Cl− levels decreased in pesticide-exposed fish at both exposure periods and in Cu- and Pb-exposed fish at 21 days. The exposures
of pesticide and metals caused an elevation in K+ level at the end of the exposure period. The present study showed that observed alterations in all serum biochemical parameters
of fish-treated pesticide were higher than those in fish exposed to metals. 相似文献

The stability of free tryptophan (Trp) was examined in five cookie-resembling models at varying baking temperatures and durations. Trp was measured by HPLC coupled with a fluorescent detector. Trp degradation was significantly greater in cookies formulated with glucose compared with sucrose, regardless of the temperatures and durations of baking. A lag period was clearly observed in cookies formulated with sucrose. The type of sugar used in the dough formulation affected not only the thermal destruction kinetics but also the degree of degradation of free Trp. However, the type of leavening agent (ammonium bicarbonate versus sodium bicarbonate) did not affect the rate of Trp destruction as happens in Maillard-driven reactions. In addition, the free Trp content was analyzed in nine different flours and sixty-two commercial cookies, and it was found that free Trp varied from 0.4 to 1287.9 mg/kg for rice and wheat bran, respectively. It was found that free Trp was significantly higher in dietetic commercial samples formulated with wheat bran compared with other flours. 相似文献

With this study we investigated the effective factors on annual amount of total litterfall and needle litterfall in Pinus brutia forests and estimated them with a regression model based on certain stand parameters. We studied 27 permanent plots representing different stand structure and environmental conditions in South-Western Turkey. Litterfall was collected in three month intervals corresponding to each of four seasons for a three-year period. We found a significant relationship between litterfall and stand properties such as crown closure (%), basal area (m2?ha?1), stand stem volume (m3?ha?1), above-ground biomass (t?ha?1), mean annual volume increment (m3?ha?1?yr?1) and site index (T?=?75). Similar relationships also hold true between litterfall and each of such climatic factors as seasonal mean temperature (°C), relative humidity (%) and temperature/precipitation ratio (dimensionless). The mean annual litterfall considerably varied depending on stand characteristics and certain environmental factors. Both needle litterfall and total litterfall may be predicted for long term by regression models using certain stand parameters. Models developed for litterfall of P. brutia forests in this study may be used for national C inventory in Turkey. 相似文献

This paper reports a presumptive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in a cat. A cat with respiratory disease living with three individuals with coronavirus disease 2019 showed bilateral ground-glass opacities in the lung on X-ray and computed tomography. The clinical swabs were negative for SARS-CoV-2 RNA, but the serum was positive for SARS-CoV-2 antibodies. Interstitial pneumonia and prominent type 2 pneumocyte hyperplasia were noted on histopathology. Respiratory tissues were negative for SARS-CoV-2 RNA or antigen, but the cat was positive for feline parvovirus DNA. In conclusion, the respiratory disease and associated pathology in this cat could have been due to exposure to SARS-CoV-2. 相似文献
