Page 19 - Thus far, then, it has been shown, that the amounts of food, or of its various constituents, consumed, both for a given liveweight of animal within a given time, and to produce a given amount of increase, were very much more dependent on the quantities of the non-nitrogenous, than on those of the nitrogenous constituents, which the food supplied. It has been said, that when the large requirement for...
Page 1 - Bearing then those points in mind, which must tend to modify the indications of the actual figures in the Tables, it will appear, we think, that the coincidences in the amounts of available respiratory and fat-forming constituents, consumed by a given weight of animal within a given time, or to produce a given amount of gross increase, are much more strikingly shown throughout the numerous results represented in these Tables, than a priori we could have expected to find them. With this general uniformity,...
Page 22 - Pigs — if we consider that it is the results obtained under the subtle agency of animal life, that we are seeking to measure and express in figures — and if we also bear in mind the various sources of modification to which our actual figures must be submitted, in order to attain their true indications, we think it cannot be doubted that beyond a limit below which few of our current fattening Pig foods are found to go, it is rather their...
Page 31 - Hampshire and Sussex Downs being made together in 1850-1, those of the Cotswolds alone in 1851-2, and those with the Leicesters and cross-breds in 1852-3. And although the quality of the respective foods was in all cases as nearly alike as circumstances would allow, yet the actual stocks used were different for the three seasons.
Page 6 - ... of both fat and total dry substance, and a lower one of both nitrogenous compounds and mineral matter, than that of the younger and more moderately fattened animal. As a general result, it appears that about...
Page 3 - ... increase. Thus, in reading the figures of the Tables, allowance has to be made, both for those of the non-nitrogenous constituents of the food, which would probably become at once effete, and also for the different respiratory and fat-forming capacities, so...
Page 77 - animals — consists of a much larger proportion of fat, and a much less one of nitrogenous compounds, than is usually supposed. The whole question of Animal Composition, however, as illustrated by the experiments referred to, we hope to treat of separately, on some other occasion. But, apart from the considerations involved in the question of the varying composition of the Increase, or from the fact that our own feeding experiments (which, so far as we are aware, are the largest comparable series...
Page 64 - Sheep seemed to indicate — namely, that, as our current fattening food-stuffs go, both the amount consumed by a given weight of animal, within a given time, and that required to produce a given amount of increase...
Page 27 - That the cross-breds consumed slightly more food, in relation to a given weight of animal, within a given time, than the Leicesters.
Page 1 - ... 2. The amount of food, and of its several constituents, consumed to produce a given amount of increase in live-weight. 3. The proportion, and relative development, of the different organs or parts of different animals. 4. The proximate and ultimate composition of the animals, in different conditions as to age and fatness, and the probable composition of their increase in live-weight during the fattening process.
