“…However, these effects may only be marginal with regard to the range of oil included in the diet, as the digestibility of dry matter was not impaired by the supplement levels tested (Santana et al 2013). Even the high levels of EE in the concentrate (56.4 g kg (1 ) accounted for very little of the total dietary value.…”

“…However, these results apply to diets based on Tanzania grass as a roughage resource with an NDF level greater than 70%. Other studies using diets based on corn silage (Smith et al 1993) and grass (Grant and Weidner 1992) have demonstrated less tolerance to the addition of soluble fatty acids. For future analysis, the association of licuri oil with another types of roughage should be evaluated.…”

(1 of licuri oil in concentrated dry matter. The intakes of dry matter, crude protein and non-fiber carbohydrate levels were not affected by the addition of licuri oil; however, the intake of neutral detergent fiber and total digestible nutrients decreased linearly. Neutral detergent fiber digestibility was reduced linearly with increasing levels of licuri oil in the concentrate. There were no changes in blood glucose levels, but blood urea nitrogen levels varied according to the time of the day when the blood was collected. Inclusion of licuri oil at 45.0 g kg (1 in feed concentrates results in improved dry matter and ether extract digestibility.

“…This corroborates the recommendation of Euclides et al (2012), in which reduction in stocking rate showed to be a viable alternative to the use of pastures of P. maximum cultivars during the dry season. Santana et al (2013) observed that only adjusting the stocking rate as a function of forage mass at the beginning of the dry season made it possible to obtain an average daily gain of 530 g per calf, in tanzania guinea grass pastures (Panicum maximum cv. Tanzânia).…”

“…In this context, Santana et al (2013) found that only adjusting the stocking rate as a function of forage mass at the beginning of the dry season made it possible to obtain a daily gain of 530 g per calf (1/2 Angus-1/2 Nellore; Braford 1/2-1/4 Angus-Nellore; and 1/4-1/2 Brahman-1/4 Angus-1/4 Nellore) in tanzania guinea grass pastures.…”

“…On the other hand, protein and energy supplemental feeding during this critical period are an effective way to improve the nutritional status of the animals, and consequently animal performance Santana et al, 2013;Morais et al, 2014). Euclides and Medeiros (2005) built a database from results published in Brazil that used protein and energy supplemental feending during the dry season.…”

The objectives were to: 1) evaluate the potential of the animal performance on Panicum maximum cv. Mombaça (mombaça guinea grass) pasture during dry season, and 2) determine the effects of protein or protein-energy supplementation on liveweight gain of steers grazing guinea grass pasture. A complete randomized block design was employed with three treatments and three replicates. Treatments included non-supplemented animals (NS) and animals supplemented with protein (PS) or protein-energy (PES), provided at 0.15% or 0.6% of body weight for 115 days, during dry period. We used 36 weaned calves from initial bodyweigh (LW) of 192 kg (±5 kg) on nine plots of mombaça guinea grass (1.25 ha each). Each month, animals were weighed and pastures sampled to estimate forage characteristics. The average daily gain (ADG) was greater (P = 0.0001) for cattle fed supplement than for cattle fed no supplement (250 g steer ). Mombaça guinea grass pastures with 45 cm height at the end of the wet season have enough forage mass for maintenance throughout the dry season about 1.4 AU ha -1 (AU = 450 kg BW), and reasonable nutritive value (average of 8,1% of crude protein and 55,3% of in vitro organic matter digestibility) to provide small gains. Considering the nutritive value of Mombaça guinea grass during the dry period, protein and energy supplementation is required for weaned calves to optimize their performance.

This study aimed to evaluate the intake, digestion, blood parameters, and feeding behavior of crossbred dairy cows (Holstein × Gir) managed on Panicum maximum Jacq. cv. Tanzania-1 and provided supplementation with groundnut cake, sunflower cake, or palm kernel cake (to replace soybean meal). Sixteen cows were randomly assigned in a Latin square design with four treatments and four experimental periods. The consumption of nutrients from the pasture did not vary between experimental treatments. Cows receiving the palm kernel cake supplement had a reduced crude protein, non-fibrous carbohydrate, and total digestible nutrient intake and an increase in the average consumption of ether extract. There was also a reduction in the digestibility of dry matter. The inclusion of supplements in the diet did not influence the average time spent eating, ruminating, or resting. The mean values of respiratory and heart rates showed thermal comfort during the trial period. There was a reduction in blood urea nitrogen with palm kernel cake supplementation, and the values of total protein, albumin, and glucose were also significantly different with this supplement. It is recommended that cakes of groundnut cake and sunflower cake seed be used for a total replacement of soybean meal supplements for lactating cows, but the use of palm kernel cake is not recommended.
