Daily BW velocity (BWV) and acceleration (BWA) of individual birds have been demonstrated to be oscillatory. Daily feed intake velocity (FIV) and acceleration (FIA) were hypothesized to be oscillatory and to have a positive relationship with BWV and BWA, respectively. Forty-eight male broiler chicks were individually caged and provided a commercial starter feed ad libitum for 49 d. BW and feed ...
SUMMARY Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa m eal at levels of 2, 3, 4, 5, 6, 9, O, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth d e-press ion was evident in comparable lots. In addition duplicate trials of four lots of n ewly hatched New H ampshire chicks...
In this study, we compared the digestibility levels and in vitro fermentation parameters of total mixed rations (TMRs) containing 20% 40% defatted black soldier fly (Hermetia illucens) larvae (BSF) as a substitute for soybean meal (SBM) basal ration (60% roughage/40% concentrated feed) dairy cows. We evaluated volatile fatty acid (VFA), gas production, methane emission, ammonia, pH, carbon diox...
{ The paper describes progress in the modelling of penetration and coupling in conngu-rations relevant to EMC. The application of the TLM method in modelling eeciently thin nite-conductivity panels and thin wires is outlined. Comparisons with experimental and theoretical results show that inexpensive numerical models are accurate enough for EMC studies and hence that whole system modelling is b...
The expansion of export demand for sheep meats has led to a resurgance of interest by producers in short term feedlot systems of fattening for sheep and lambs. Apart from the cost of rations, the incidence of disease and metabolic disorders is an important determinant of profitability. This paper describes a feedlot experiment at Hamilton during which an outbreak of polioencephalomalacia (PEM) ...
Introduction New poultry feed valorization pathways for recovered household food could be enabled by commercially available devices that dry uneaten material, arrest spoilage, and preserve nutrient content. However, the composition, safety, incorporation potential of dried (DRHF) is presently unknown. Methods Thirty-eight households spanning 31 states participated in a 4-to-6-week survey to gen...
BACKGROUND Loss to follow-up (LTF) after antiretroviral therapy (ART) initiation is common in HIV clinics. We examined the effect of availability of adherence support and active patient outreach services on patient attrition following ART initiation. METHODS AND FINDINGS This ecologic study examined clinic attrition rates (total attrition, LTF, and death) among 232,389 patients initiating ART...
BACKGROUND Decades of civil conflict compound the challenges of food insecurity in South Sudan and contribute to persistent, high levels of child malnutrition. As efforts to prevent child malnutrition continue, there is a critical need for strategies that effectively supplement the diets of pregnant women and young children in transitional, highly food insecure settings like South Sudan. METH...
A six-week trial was conducted to study the effect of decreasing dietary crude protein (CP) level on the performance of broilers in hot climatic conditions. Four experimental rations having CP 23 (control group), 22, 21 and 20%, with optimal amino acid balance were prepared. All the four rations were isocaloric having ME 3200 kcal/kg with Energy: Protein (E:P) 139.0, 146.5, 152.4 and 160 in die...
