“…The results given in Table 5 are in agreement with those obtained in earlier investigations (Holland & Buckley, 1918, 1923Sutton, Brown & Johnston, 1932;Hilditch & Thompson, 1936;Hill & Palmer, 1938;Williams et al 1939;Hilditch & Jasperson, 1943) which established that the inclusion of vegetable oils such as groundnut, maize, soyabean or linseed oils in the diet of the lactating cow increased the iodine value but decreased the Reichert and Polenske values of the milk fat. Hill & Palmer (1938), Stull, Harland & Davis (1957 and Larsen (1958) all reported that the addition of tallow to the diet of the cow resulted in an increase in the iodine value of the milk fat.…”

“…The method of incorporating the fats or oils in the diet may determine the effect on milk fat production. For example, Williams, Cannon & Espe (1939) and Williams (1941) observed that more milk fat was produced by cows given whole oil seeds than by cows given a mixture of the extracted seeds and the oil that had been obtained from the seeds. Moore, Hoffman & Berry (1945) demonstrated that the yield of milk fat was reduced when cod-liver oil was given once each day but was unaltered when the same total amount of cod-liver oil was given in the form of several smaller doses during the day.…”

SummaryThe effects of the isocaloric replacement of part of the dietary concentrate mixture by either tallow or cottonseed oil on the yield and composition of the milk fat was investigated in 2 feeding experiments with a total of 26 cows in midlactation. The concentrates were given with high- or low-roughage diets that supplied either 9·1–9·5 or 1·8–3·2kg hay/day.In expt 1, the addition of cottonseed oil to the high-roughage diet increased the yield of milk fat during the first 8 days but decreased it during the last 4 days of a 28-day feeding period. In contrast, the inclusion of tallow in the high-roughage diet resulted in an increased yield of milk fat that was sustained throughout the period of 28 days. In expt 2, the intake of dietary fat was less than it was in expt 1 and the inclusion of tallow or cottonseed oil in either the high- or low-roughage diets had little effect on the yield of milk fat.The inclusion of either fat in the diet increased the yields and percentages of stearic and oleic acids and, in general, decreased the yields and percentages of the medium-chain fatty acids (10:0, 12:0 and 14:0) in the milk fat. The addition of tallow to the diet did not appear to alter the yields of the short-chain fatty acids (C4–C8, 4:0, 6:0 and 8:0) in the milk fat. When the low-roughage diets resulted in a decreased yield of milk fat, the secretion of all the fatty acids in the milk fat was reduced, but the reduction in the secretion of oleic acid was less than the reductions in the secretions of the other constituent fatty acids.
