An account has been given of recent work on the chemical nature of war-time swill and on the best methods of using this product so as to ensure the maximum replacement of concentrates, consistent with economical live-weight gains, in the rations of bacon pigs.Three different types of swill have been submitted to investigation: (1) a meat-rich military camp swill, characteristic of the material available during the first 18 months of the war; (2) processed urban swill, commonly known as concentrated swill; and (3) dried, balanced swill. In addition, the results of an investigation into the variation in composition of household and restaurant swill are also given.The different types of swill have been examined from the standpoints of (1) main ingredients, (2) chemical composition, both organic and mineral, (3) digestibility, when fed to bacon pigs, and (4) nutritive value in comparison with mixtures of common pig foods. The keeping qualities of processed urban swill and dried, balanced swill have also been investigated, and attention has been devoted to the problem of the seasonal variations of urban swill in respect of main ingredients, chemical composition and feeding value.

SUMMARYHerbage availability, intake and nutritive value were recorded on swards of S. 59 red fescue (Festuca rvbra L.) and S. 23 perennial ryegrass (Lolium perenne L.), with and without S. 184 white clover (Trifolium repens L.), and correlated with animal performance. Intake of dry matter was similar on all treatments. Animal live-weight gains during 1969 were positively correlated with digestible organic matter intake (DOMI).Poor animal performance from red fescue swards in mid-summer was attributed to the rapid fall in digestibility at this time which affected DOMI.Differences between treatments in efficiency of conversion of DOMI into live-weight gains were observed. Superior conversion ratios in swards containing clover could not be related to any of the herbage quality measurements recorded.Better animal productivity from red fescue swards in early spring and in late autumn were related to the longer growing season of this grass.The merits and demerits of red fescue as a grass for hill conditions and the possibility of reducing its limitations by breeding are discussed.

Previous studies conducted at Newcastle with a lactobacilli silage inoculant(Pioneer Brand 1177) had shown that when compared to an untreated control silage, the silage produced with the Inoculant had improved chemical composition. The benefits of applying the inoculant were further seen in improvements in nutritive value and voluntary food intake by sheep.

Feeding Value

The chemical composition and feeding value of seven tropical legumes and lucerne were determined by pen feeding experiments with sheep. Most of the legumes were harvested during autumn and winter. Lucerne had the highest feeding value and the highest values for the tropical legumes were obtained for Vigna vexillata, Lotononis bainesii, and Desmodium uncinatum. After frosting, the feeding values of Phaseolus lathyroides and Vigna vexillata were reduced but that of Desmodium uncinatum was not changed. This may have been due to a greater loss of leaf by both P. lathyoides and V. vexillata than by D. uncinatum. Frost did not affect Lotononis bainesii and Medicago sativa, and both had a higher feeding value than the legumes affected by frost. The usefulness of crude protein and crude fibre for estimating dry matter digestibility and dry matter intake and the relation between dry matter digestibility and dry matter intake is discussed. The use of dry matter digestibility to express the nutritive value of feed energy in preference to organic matter digestibility, starch equivalents, and total digestible nutrients is also discussed.

Feeding Trials

Daily weight gains of sheep in pure sward grazing trials showed relative feeding values to be in the order: white clover (100) > sainfoin (97), Maku lotus (87) > lucerne, red clover (78) > perennial ryegrass (52). The high feeding value of lotus and sainfoin may be due to the presence of condensed tannins which have been shown to improve protein digestion and utilization in indoor feeding trials.

The Cost

Background: Substitution of expensive protein sources like soybean meal with lower cost ingredient like rice distillers dried grain with solubles (rDDGS) would reduce the cost of the feed. Various enzymes supplementation may be used to increase their inclusion level. Methods: An in-vivo study of 42 days was undertaken (n= 384) in broilers divided into 12 dietary treatments as per 3x4 factorial design. Two levels of rDDGS consisted of 12.5 and 15% without and with three different types of enzymes xylanase, protease and multienzymes were used to find out substract specific enzyme. Result: Overall the growth performance of broiler chicken was significantly lower at 15% rDDGS level as compared to control and 12.5% rDDGS level. However, it was significantly (P less than 0.01) improved by supplementation of any of the three enzymes (xylanase, protease and multienzymes) in 12.5 and 15% rDDGS groups. Nitrogen retention, dry matter and energy metabolizability were significantly (P less than 0.01) improved in all enzymes supplemented groups. The cost of feed per kg live weight and meat yield was significantly (P less than 0.01) lower at 12.5% rDDGS with enzymes supplementation. Thus, it is concluded that the enzymes supplementation can increase inclusion level of rDDGS from 12.5 to 15% for economic broiler production.

The present investigation was undertaken with the object of ascertaining the effect of cutting at fortnightly instead of weekly intervals on the yield of pastures, and on the composition, digestibility and nutritive value of the herbage.The main trial was carried out on the 1925 light-land pasture. The plot was divided into 14 sub-plots, and one sub-plot was mown per day. The whole plot, therefore, was cut over once per fortnight during the season. The results in respect of yield, composition and nutritive value were compared with corresponding results obtained on the same pasture plot under a system of weekly cuts during 1925.A second trial was carried out on sub-plots 2 and 3 of the 1926 heavy-land pasture, one sub-plot being cut weekly and the other fort-nightly. The work in this case was restricted to securing comparative data in respect of yield and composition of herbage.The results from both trials lead to the conclusion that the differences in chemical composition, both organic and inorganic, between pasture grass cut at weekly and fortnightly intervals are inconsiderable. The dry matter of the fortnightly-cut grass is extremely rich in crude protein and contains, in comparison with grass cut at the hay stage of maturity, a low percentage of crude fibre. Moreover, these characteristics are retained, by systematic cutting at fortnightly intervals, over the entire season.The results of the digestion trials justify the conclusion that the dry matter of the pasture herbage grown under a system of fortnightly cutting is a protein concentrate equal in digestibility and nutritive value to that obtained by weekly cutting. There is no significant running off in respect of composition and feeding value during the second week of growth. At the end of a fortnight the herbage still consists of the same immature, non-lignified. tissue as it was at the end of a week's growth.

The investigation which has been dealt with in this communication was essentially a continuation of earlier work carried out in 1925 and was primarily designed with the object of ascertaining whether, under greatly differing conditions in respect of soil, herbage and weather, the striking results obtained in the 1925 investigation concerning the chemical composition, digestibility and nutritive value of pasture herbage, under a system of cutting resembling the conditions of close grazing, still held good.

The effects of the biological insecticides Madex and Agricolle, applied alone or in combination with the biological fertilizers Lithovit and Nagro, on chemical composition and enzyme in vitro digestibility, as well as energy feeding value of alfalfa dry mass were studied. Treatments were carried out at the beginning of the flowering stage during the second cutting for control of economically important pests, testing a method of organic pest control. Independent and combined applications of several biological products were found to influence positively the chemical composition, enzyme in vitro digestibility, and energy and protein nutritional value of alfalfa feed. An optimal combination of decrease in the content of plant cell wall fiber components and a significant increase in forage enzyme in vitro digestibility was revealed after the application of Agricolle and a combination of Agricolle and Nagro. Digestibility reached 60.4 and 59.9%, respectively, which is an increase of 12.0 and 11.0%. Alfalfa low fiber, high protein content, and digestibility made a very good complement to grains and other forages in dairy rations after treatment with biological products.

1. Twenty-four individually fed yearling Ayrshire heifers were used to compare diets consisting of (1) long barley straw and concentrates; (2) the same quantities of similar foods as in (1) but with most of the barley straw ground and pelleted with a proportion of the concentrates in a ratio of 70:30; (3) replacement of the whole of diet (1) by the pelleted 70:30 mixture to provide a similar theoretical starch-equivalent intake.2. Live-weight gains over an experimental period of 10 weeks were: treatment 1, 0.55 lb./day; treatment 2,0.99 lb./day; treatment 3,1.23 lb./day. These differences were statistically significant and indicated a marked response in energy value due to processing the straw.
