Previous studies from this laboratory have dealt with the protein, calcium, phosphorus, vitamin D, manganese, zinc, riboflavin, niacin and choline requirements of pheasants (Scott, et al., '54, '58a, '59) . The phosphorus requirements of young Bobwhite quail also have been reported (Scott, et al., '58b). Although many studies have been made on the effects of various levels of salt in rations fo...

One of the fundamental principles of dairy nutrition is the need to formulate rations to maximize energy intake for high producing cows. We have improved our ability to predict dry matter intake (DMI) and can formulate rations for increasingly precise fractions of carbohydrate, but a major limitation to the science of carbohydrate allocation continues to be the unaccounted variability in starch...

An experiment was conducted to investigate the effect of different crude protein (CP) levels on the growth performance of Awassi lambs and Black goat kids. Forty lambs and 40 kids were randomly selected and allocated to separate pens of equal size for 75 days. Each group was fed one of four rations containing 12, 14, 16, or 18% CP. Final weights and gains for lambs were higher (P<0.001) than th...

Predictive models for the exponential growth rate (EGR) and germination, outgrowth, and lag times (GOL) of Bacillus stearothermophilus previously developed in our laboratory were expanded to include higher salt (1.5%) formulations. The expanded models were validated in 7 military meals-ready-to-eat incubated at temperatures from 45 °C to 60 °C, and tryptic soy broth incubated from 37.5 °C to 70...

Four rations that differed in their crude protein and essential amino-acid content were compiled. Digestibility of the crude protein and essential amino-acid contents were determined biologically in a feeding trial using 4 Anglo-Arab stallions. Their respective daily diets were: Diet 1:2 kg cubes, 5 kg tef hay (Eragrostis tef); Diet 2:2 kg cubes, 5 kg lucerne hay (Medicago sativa); Diet 3:2 kg ...

While studying the nicotinic acid-tryptophan relationship in rats on low casein rations containing choline (2), yellowish livers were observed on autopsy. These livers upon analysis were found to contain 16 per cent lipide. When an amino acid mixture containing threonine, valine, and histidine was added to the ration, normal liver lipides were found. A systematic study of the effects of these a...

responses to sugars in dry or liquid formvary from study to study. when fed in proper amounts, sugars should not depress ruminalph, and there is some evidence that they actuallyhelp toprevent a drop in ph after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. adding sugars doesprioritize the need for rumen degraded protein (rdp).we all know, sugars...

This study aims to determine the quality of chicken eggs Lohman Brown has given fish oil in rations. The design used was a completely randomized (CRD) with total 160 chickens 4 treatments and replications each replication consisted 10 chickens. P0: Ration without oil, P1: using 0.2% P2: Rations 0.3% P3: 0.4% oil. feed is composed ingredients, namely corn, bran, concentrate, mineral, flour. vari...

1. The effect of various percentages of protein (casein) in the diet on the serum protein concentration of the rat was studied. 2. With high protein rations (50 per cent or over) there is no drop at all of serum protein concentration, even though the diet is otherwise poorly balanced and inadequate as evidenced by weight loss. 3. With protein rations under 20 per cent the serum protein concentr...
