“…Raven and Robinson (14) have reported a low absorption of Ca and P associated with a relatively large faecal excretion of fatty acids in young calves fed diets containing palmkernel oil. Elsplin et al (8) added tallow and hydrolysed vegetable and animal fat to a high concentrate ration used for fattening steers. The fat additions increased the faecal soaps significantly over the control ration which contained no added fat, but the absolute increase was relatively small.…”

The Effect of the Addition of Arachis Oil on the Conservation of Heavily–wilted Herbage Sealed in Polythene Film

A conservation experiment is described in which arachis oil was used to improve the energy content of heavily-wilted herbage of approximately 46% dry matter. The 2 oil-treated herbages and 2 control silages were enclosed in polythene film. The DM losses from all 4 silos were high compared with losses normally encountered in completely sealed silos. This is attributed to secondary fermentation which occurred after the silos were opened. The oil had a depressing effect on the digestibility of the mineral matter of both grass and silage. The metabolizable energy values of the silages are reported and discussed.

“…Most data in the literature show no effect or a decrease in fibre digestibility when fat is added. However, some authors (Esplin et al 1963;Palmquist & Conrad 1978;Perry & Stewart 1979;Mir 1988) have found a positive effect, sometimes significant or higher than 5 percentage units of digestibility with different sources of fat comprising 3-10% of the diet. With calcium soaps, as with triglycerides, Olubobokun et al (1985) found the same result.…”

SUMMARYTwo groups of nine wethers, three of which were fitted with rumen cannulas, were used in a digestion trial at the INRA centre in Theix, France, in 1988. Group 1 received 65% maize silage and 35% concentrates; group 2 received 65% hay and 35% concentrates. Concentrates were based on either cereals rich in starch, or by-products rich in fibre and were given either alone or supplemented with lipids as calcium soaps. The fatty acid content of lipid-supplemented diets wasc.9·5 and 8·5% of dry matter, of which 85 and 89% was provided by calcium soaps, for maize silage and hay diets, respectively. For each group, the four diets were tested in four successive periods from January to June 1988.Total digestibility of dry and organic matter, acid detergent fibre (ADF) and neutral detergent fibre (NDF) was measured in six wethers of each group by total faeces collection. On cannulated wethers, volatile fatty acid content and composition, pH and NH3-N in rumen liquor were determined four times a day;in saccodegradability of dry matter, ADF and NDF of the forage eaten by the wethers was estimated by the kinetics of incubation in the rumen.In vivoandin saccoresults showed that dry matter and organic matter digestibilities were not modified by the nature of concentrates. Cell wall digestibility was higher for fibre concentrates than for starchy concentrates, by 4·1 and 6·2 percentage units for NDF in maize silage and hay groups, respectively. Volatile fatty acids (VFA) and ammonia concentrations were higher and pH was lower with the maize silage than with the hay diet.Lipid supply slightly increased cell wall digestibility in the group fed maize silage by 7·5 and 2·0 percentage units for starch and fibre concentrates, respectively. This surprising increase was related to an improvement inin saccodegradability. In all diets, lipid supply increased pH, but variations in VFA concentration and pattern were low. Interactions between the nature of concentrate and lipid supply were moderate, but were higher in the group fed maize silage than in the group fed hay, especially for total digestibility.

“…In trials on cattle it has been shown that dietary fat, given in the form of tallow, expecially in conjunction with high protein feeds (Erwin, Dyer & Ensminger, 1956;Bohman, Wade & Hunter, 1957;Hubbert, et al 1961;Esplin et al 1963), increases both growth rate and efficiency. Dietary tallow has also been shown to increase the quantity of subcutaneous fat in steers (Albin & Durham, 1967;Bohman & Wade, 1958).…”

SummaryThe feed conversion efficiency of four intensively fed, partially castrated male cattle, measured over an 11-week period from approximately 9-months of age, was found to be significantly higher (P <0·05) than that of four steers.The effect of adding 5% beef tallow to the diet during this period was also studied. Although no statistically significant result of this on feed conversion was obtained, there was an indication that fat in the diet improved the bulls' efficiency, but not that of the steers. Added dietary fat had an effect on carcass composition, increasing signifioantly (P < 0·05) the deposition of carcass fat by steers but having no such effect in bulls. It appears, therefore, that the two sex types metabolized the added dietary fat differently, the steers converting much of it to depot fat; the bulls using it (with some evidenoe of greater efficiency) for growth of non-adipose carcass components.
