This study was conducted to investigate the effect of vegetable oil and yeast fermented cassava pulp (YFCP) supplementation on feed intake, nutrient digestibility and rumen fermentation in Thai Friesian dairy cows (Thai native x Holstein Friesian). Eight Thai Friesian dairy cows (447±44 kg.BW) were assigned to 4×4 double latin square design (DLSD) with two sources of oil i.e. palm oil (PO) or soybean oil (SBO) and four levels of YFCP (0, 5, 10 and 20%DM) in the dietary treatments. All cows received total mixed ration (TMR) comprised of rice straw to concentrate at a ratio of 40:60. The results showed that supplementation of SBO had lowered feed intake, nutrients digestibility, metabolize energy intake (MEI), total digestible nutrient (TDN) and methane emission than PO treatment. However, cows received SBO had greater total volatile fatty acid (TVFA), propionic acid (C3), butyric acid (C4) than cows received on PO (P less than 0.05). In addition, supplementation of YFCP at 10%DM in the diet as an optimum level in dairy cow diets (P greater than 0.05). Finally, the interaction between the addition of SBO and YFCP at 10%DM (SBO+YFCP) had a positive effect on enhancing ether extract intake (EEI) in dairy cows.

The problem of sheep grazing in the deserts of Rajasthan is that animals do not get drinking water for 2–3 days at a time. Studies carried out at this Institute, on water deprivation in sheep, have indicated that sheep deprived of water for 72 h did not show any adverse effect on wool yield, in spite of the fact that water deprivation reduced feed intake (More & Sahni, 1972). The present experiment is a part of extensive studies carried out on water deprivation with particular reference to sheep production. The paper describes the influence of water deprivation on nutrient digestibility and nitrogen retention in sheep.

Conserving good source of roughage for dry-season feeding of ruminants is of the utmost importance. Therefore, cassava-top silage (CTS) was prepared and was studied for its feeding level and nutritive value in dairy steers. Four rumen-fistulated dairy steers (75% Holstein Friesian × 25% Thai Native), ~3 years old with 209 ± 50 kg liveweight, were randomly assigned according to a 4 × 4 Latin square design to study the effect of CTS on feed intake, nutrient digestibility and rumen fermentation efficiency. The treatments were four different feeding ratios of CTS to rice straw, as follows: 0:100, 30:70, 60:40 and 100:0 respectively. Increasing the ratio of CTS to rice straw in the feed remarkably reduced the rumen protozoal population (P < 0.01), thus subsequently decreasing rumen methane production (P < 0.01), whereas other rumen microorganisms remained similar among treatments. Correspondingly, rumen propionate production was enhanced (P < 0.01) by increasing the CTS to rice ratio in the feed, and the acetate:propionate ratio decreased (P < 0.01). Furthermore, rumen ammonia nitrogen and blood urea nitrogen increased (P < 0.01) with an increasing proportion of CTS in the feed, whereas nitrogen retention was highest when the proportion of CTS in the feed was 100%. Although the feed DM intakes were similar, apparent digestibilities of DM, organic matter, crude protein as well as neutral detergent fibre and acid detergent fibre were significantly improved by the increase in the percentage of CTS in the feed. It could be concluded that including CTS in the feed at a level of 60–100% improved the rumen fermentation, nitrogen balance and nutrient digestibilities, and is highly recommended for use in the ruminant production in the tropics, as it is a practically simple-to-prepare on-farm feeding intervention.

Zenobi, M. G., Lardner, H. A., Jefferson, P. G. and McKinnon, J. J. 2015. Effect of feeding strategically blended feed pellets on rumen fermentation and nutrient digestion. Can. J. Anim. Sci. 95: 243–254. Five rumen-cannulated heifers (631±31 kg) were used in a 5×5 Latin square design to evaluate the effect of feeding blended by-product feed pellets (BP) on rumen fermentation and nutrient utilization. Four BP were formulated to be high in starch (HS) or fat (HF) and either low (LSP) or high (HSP) in soluble crude protein. The control diet consisted of 49.1% forage and 50.9% barley-based concentrate. Treatments were 50.3% forage and 49.7% BP (DM). Heifers fed HF BP had higher (P=0.05) mean pH values than those fed the control diet and tended (P=0.07) to have higher mean pH than those fed the HS BP. Feeding HF BP decreased (P<0.05) rumen propionate concentration without affecting acetate or total volatile fatty acid concentration. Rumen ammonia-nitrogen (N) levels and digestibility of crude protein was highest (P<0.05) for HS, intermediate for HF, and the lowest for the control. Feeding HF BP reduced (P<0.05) gross energy digestibility and digestible energy content relative to both the control and HS diets while both BP increased (P<0.01) their extract digestibility compared with the control. There was minimal effect of pellet soluble crude protein content. Total N excretion (% of N intake) was not affected (P>0.05) by treatment. These results indicate that BP had no adverse effects on rumen fermentation or apparent nutrient digestibility and did not result in issues with excess nutrient excretion. As such BP can be used as an alternative energy source in backgrounding diets to cereal grains and can help counteract volatility in feed grain prices.

Forage Diets

A feedlot trial and a digestion and nitrogen balance trial were carried out to evaluate the effect of feeding one (1 ×) or four times (4 ×) daily on the utilization of two high-forage diets. On a dry matter basis, diet 1 contained 76% alfalfa haylage and 22% high-moisture corn; diet 2 contained 93% corn silage and 4% soybean meal; the balance was composed of mineral and Rumensin premixes. In the feedlot trial, feed was offered ad libitum, and feeding frequency resulted in small differences in eating patterns within diets. Thus, rate of gain, feed intake and conversion were not significantly affected. In the digestion trial, feed intake was restricted to 90% of each individual's maximum intake, which resulted in larger differences in eating patterns between 1 × and 4 × feeding. Under these conditions, feeding frequently increased (P < 0.05) dry matter and organic matter digestibility, as well as N retention (percent of N intake). Increased feeding frequency had no beneficial effects under ad libitum feeding of high-forage diets. However, under restricted feeding, feeding more frequently improved total diet digestibility and nitrogen retention. Key words: Cattle, feeding frequency, digestibility, growth, nitrogen retention
