Simulation of weight gain and feed consumption of turkeys
… economic importance, namely body weight and feed consumption. Existing weather simulation models were combined and modified in order to develop a model that predicted daily dry-bulb temperature and humidity ratio outside the turkey house. The weather simulation model was validated using …

Flavor effects on feed consumption and performance of dairy cattle in early lactation
… investigate the potential effects of flavors on feed consumption of dairy cows in early lactation. Two sequential elimination trials, each with six multiparous Holstein cows, were conducted to test the effects of additives on the preference ranking of diets. Starting eight days postpartum cows …

Influence of Winter Housing Conditions on Growth Rates and Feed Consumption of Dairy Heifers
… their growing period are carefully managed as to feed, housing and care to promote normal growth. However, they are often neglected during their yearling stage to the point where growth is retarded because of environment factors. On many dairy farms in the North Central States the management of …

Day-to-Day Variation in the Feed Consumption of Dairy Cows in Early Lactation
… a control or a liquid-flavored (0.52 ml/kg of feed) totally mixed ration in a randomized complete-block design. Weekly means of DMI, milk production, and body weight were analyzed. Individual cow daily DMI data were fitted to the exponential model. There was no effect of treatment on these …

A method of estimating the feeding value of swine pastures
Estimates of feed produced by pasture were obtained from pasture investigations at the Tidewater Field Station from 1949 through 1953, Dry lot groups of pigs similar to those fed on pasture and fed similar rations were used to estimate total concentrates necessary for maintenance and gain of pigs …

Effects of Dieldrin on Reproduction of Penned Hen Pheasants
… significantly higher for an undetermined reason. Feed consumption, egg production, fertility of eggs, and weight gain and survival of chicks were not affected by the treatments. The second season, treatment levels were 0, 2, 4 or 6 mg of dieldrin per hen per week. It appears that the 2 and 4 mg …

Characterization of creep feeding and its subsequent effects on immune response, scouring index, and performance of weanling pigs
… were conducted to examine the pattern of creep feed consumption of nursing pigs and the effect of creep feeding - from 10 d to weaning at 28 d - a 20% crude protein corn-soybean meal and dried whole whey diet (REG, 9 litters) containing 1.0% chromic oxide for detection of creep feed consumption, …

Effects of Glucocorticoids and Limited Nursing on the Digestive Enzyme Ontogeny and Growth of Nursing Piglets (Maltase, Sucrase, Lactase, Amylase, Acth)
… The response of these enzymes to increased creep feed consumption, produced by partial weaning, was also investigated. A total of 87 litters of piglets were used.

Simulation of a swine nursery to facilitate economical management
… of swine nurseries by predicting pig growth and feed consumption, building fuel consumption, and cost per unit of gain produced. lt was based on an existing swine model that was converted to an hourly basis. An optimization option was incorporated into the operational model to allow minimization …

Physical and chemical effects of pelleting feed on broiler growth and behavioral parameters
… had been pelleted at 55° or 85°C. In an 8-week feeding trial, the subjects receiving pellets processed at the higher temperature experienced significant (P ≤ .05) weight gain over those receiving the diet processed at 55°C. Although feed consumption for this treatment increased as well, the …

Nutritional parameters associated with enteric Escherichia coli and rotavirus in poults
… poults produced a significant increase in feed efficiency by 21 days of age for birds fed either 28 or 22°0 protein diets. In this case, E. coli apparently was established as part of the normal intestinal microflora of the turkey without producing a toxic response. Similar concentrations of …

Effects of added dietary fat and protein on the growth and carcass characteristics of turkeys
… fat up to 10% increased body weight gain .72%. Feed consumption decreased 1.3% and feed efficiency increased 2.3% for each 1% added fat up to 15%. Addition of Fat 2 to the diet resulted in significantly better feed efficiencies as compared with Fat 1 or Fat 3. The feeding of low protein diets as …

The ontogeny of the immune response to sheep erythrocytes and resistance to aflatoxins in chickens
… aflatoxin B₁. Aflatoxin depressed body weights, feed consumption and feed conversion, with feed conversion being depressed less than either body weight or feed consumption. Although there were no differences among aflatoxin levels for body core temperatures, levels of 1830 ppb and higher caused …
