The Nutritional Evaluation and Optimisation in Neonates trial has contributed significantly to our understanding of parenteral nutrition in the extreme preterm neonate (1). I was intrigued by the diff...
Background: The ω-6 (n–6) to ω-3 (n–3) fatty acid (FA) ratio (n–6:n–3 ratio) was previously shown to be a predictor of executive function performance in children aged 7–9 y.
This study was conducted to investigate the effects of raw material ratio on the physicochemical characteristics of emulsion-type pork sausages. Experiment design was divided into 12 treatments, based...
Gender selection is important in livestock industries; for example, female calves are required in the dairy industry. Sex-sorted semen is commonly used for the production of calves of the desired gend...
The objective of this study was to determine the effects of protein sources and roughage (R) to concentrate (C) ratio on in vitro fermentation parameters using a gas production technique. The experime...
The objective of this study was to investigate microbial population in the rumen of dairy steers as influenced by supplementing with dietary condensed tannins and saponins and different roughage to co...
A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amy...
Two experiments were conducted to determine an optimum Lys:calorie ratio (g of total dietary Lys/Mcal of DE) for growing barrows and gilts in cool and hot seasons in a commercial environment. In Exp. ...
This experiment was performed to investigate the effects of lysine (Lys) to DE ratio on growth performance, and carcass characterics in finishing barrows. Ninety six cross-bred finishing barrows ((Lan...
The effects of dietary lysine (Lys) at a fixed ratio to crude protein (CP) and essential amino acids (EAA) on early growth response of broilers were studied. Four diets were formulated to contain simi...
This study sought to characterize hydrogen isotopic fractionation during biosynthesis of leaf wax nalkanes in succulent plants capable of crassulacean acid metabolism (CAM). The metabolic and physiolo...
The distribution, secondary production, and calcium:tissue (Ca:tissue) ratio in relation to limno-chemical factors were studied in a freshwater limpet (Septaria lineata) population from the west bank ...
The objective of this study was to determine the optimum ratio of methionine to methionine plus cystine for growing pigs. A nitrogen balance trial was conducted using a total of 21 barrows (Large Whit...
The numbers of membrane proteins in the current genomes of various organisms provide an important clue about how the protein world has evolved from the aspect of membrane proteins. Numbers of membrane...
In the present work, gonad development and sex ratio of sharptooth catfish (Clarias gariepinus) cultured under laboratory conditions over 365 days from hatching were investigated histologically and mo...
