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.

Oil Source

The investigation aimed to study the effect of vegetable oil sources on feed intake, nutrient digestibility and biohydrogenation bacterial population in Thai Friesian dairy cows. Three fistula Thai Friesian cows with mean body weight (BW) of 600±100 kg were assigned to receive three vegetable oil sources i.e. palm oil (PO), soybean oil (SBO) and sunflower oil (SFO) included at 4 %DM in commercial concentrate. All cows were fed on different diets that contained concentrate of 1 %BW and rice straw of 1 %BW according to a 3×3 latin square design (LSD). The results revealed that dry matter digestibility (DMD) and organic matter digestibility (OMD) tended to be higher in cows fed on SBO and SFO (P=0.06). Moreover, the DNA copy numbers (copies/ml) of biohydrogenation bacteria (Ruminococcus albus) and cellulolytic bacteria (Ruminococcus flavefaciens and Prevotella ruminicola) were higher in cows fed on SBO (P less than 0.05). In summary, supplementation of SBO in diet resulted in a higher nutrient digestibility and rumen biohydrogenation bacteria population.

Goat production in northeast of Thailand has gradually increased, partly because of the limited land available to raise cattle. The other reason is that goats can give twin kids and can give birth twice a year under good management. Tomato pomace is a by product from the tomato juice factory. Dried tomato pomace is a promising protein source with high protein content. The price of dried tomato pomace is cheaper than soybean protein when expressed as price per unit protein. The trial of Yuangklang et al. (2006) found that dried tomato pomace increased growth rate in beef cattle. In dairy cows, replacing soybean meal by dried tomato pomace did not influence milk production (Yuangklag et al., 2005). Data on utilisation of dried tomato pomace in goats is limited. Therefore the present experiment aimed to investigate the effects of substitution of soybean protein by dried tomato pomace in the concentrate diet on feed intake, nutrient digestibility and nitrogen utilization of meat goats.

Since energetic deficits in dairy cows can only be reduced at an animal level, the objective of the present study was to determine the extent of variation in intake behavior within and between animals during early lactation, to explore the magnitude of interactions between feed intake, intake behavior and nutrient digestibility, and to identify levers for maximizing feed intake at the individual animal level. Feeding behavior, intake and nutrient digestibility of 28 German Holstein dairy cows, fed TMR with 7.0 MJ NEL, were studied between the 2nd and 15th week after calving. Dry matter intake was assessed daily and nutrient digestibility weekly, with iNDF240 as an intrinsic marker. Results showed high intra- and inter-individual variation in intake behavior parameters with coefficients of variation (CV) up to 0.58 in meal frequency. Nutrient digestibility varied only slightly with CV values up to 0.10 in crude protein. Milk yield, meal frequency, feeding time, feeding rate and meal size had significant positive effects on DMI (p < 0.01). To achieve long-term improvements in feed intake, it is important to optimize feed intake and feeding behavior of individual animals by improving feeding conditions and develop technical tools to identify animals with insufficient feed intake.

Yeast Product

Twenty early lactation dairy cows were used to evaluate the effects of the dietary addition of an active dried yeast product at two levels of concentrate on productive performance, nutrient digestibility, methane (CH4) emissions and energy and nitrogen utilisation. This study was a replicated 4 × 4 Latin square design with a two (concentrate level) × two (yeast supplement) factorial treatment arrangement, with four periods (6 week/period) and a 3-week interval between each period. Cows were offered grass silage-based diets consisting of two levels of concentrate (300 and 600 g/kg), with or without supplement of 0.5 g/day of an active dry yeast (Saccharomyces cerevisiae strain) with a specification of 2 × 1010 cfu/g. Feed dry matter intake, milk yield, milk composition, bodyweight and body condition score were similar between yeast treatments at both concentrate levels. Nutrient digestibility was not affected by yeast supplementation. Energy intake and faecal, urinary, CH4 and milk energy outputs were also not affected by yeast supplementation. Yeast supplementation had no effects on energy partitioning but tended to increase heat production and decreased energy retention. Yeast supplementation at two levels of concentrate had no effect on total CH4 emissions, but tended to increase CH4 per unit of feed intake and CH4 energy output per unit of gross energy intake. There were no effects of yeast supplementation on CH4 per unit of milk yield. Yeast supplementation had no effect on any variable of nitrogen intake, output or utilisation. Overall, the dietary addition of an active dried yeast product at two concentrate feeding levels had no effects on feed intake, milk production, milk composition, nutrient digestibility, or nitrogen utilisation efficiency and only tended to increase heat production, CH4 per unit of feed intake and CH4 energy output per unit of gross energy intake in lactating dairy cows.
