“…The decline in glucose from the start to the end of the grazing period is in agreement with results reported in other studies. For instance, rangeland-grazing beef cattle blood glucose decreased from summer, fall, winter to spring [ 36 ]. Similarly, a decline in blood glucose was reported for temperate-breed steers during the ‘store’ period [ 85 ].…”

“…Plasma metabolites, on the other hand, provide an integrated index of nutrient supply adequacy in relation to nutrient utilisation [ 34 ] and provide an immediate indication of the animal’s present nutritional status [ 35 ]. Animals grazing low-quality pastures during the dry season mobilize fatty acids from the adipose tissue as a long-term response to the negative energy balance resulting in elevated NEFA and BHB [ 36 , 37 ]. Supplementing animals fed low-quality grass diet with legumes improves their nutritional plane, thus minimizing catabolism to encourage anabolic processes.…”

Dietary crude protein and dry matter digestibility are among the major factors limiting feed intake and weight gain of cattle grazing native and improved pastures in the subtropics of Northern Australia during the dry season. Incorporating a suitable legume into grasses improves pasture quality and cattle weight gain, but only a limited number of legume pastures can establish and persist in cracking clay soils. This study aimed to evaluate the effect of Desmanthus inclusion in buffel grass (Cenchrus ciliaris) pastures on the plasma metabolite profile and growth performance of grazing beef cattle during the dry season. We hypothesised that backgrounding steers on buffel grass-Desmanthus mixed pastures would elicit significant changes in plasma glucose, bilirubin, creatinine, non-esterified fatty acids and β-hydroxybutyrate, resulting in higher liveweight gains than in steers on buffel grass only pastures. Four hundred tropical composite steers were assigned to buffel grass only (n = 200) or buffel grass oversown with Desmanthus (11.5% initial sward dry matter) pastures (n = 200) and grazed for 147 days during the dry season. Desmanthus accounted for 6.2% sward dry matter at the end of grazing period. Plasma metabolites results showed that changes in β-hydroxybutyrate, creatinine, bilirubin, glucose and non-esterified fatty acids were within the expected normal range for all the steers, indicating that with or without Desmanthus inclusion in the diet of grazing steers, animal health status was not compromised. It was also evident that Desmanthus inclusion in buffel grass pastures had no impact on the plasma metabolite profile, liveweight and daily weight gain of grazing steers. Therefore, our tested hypothesis of higher changes in plasma metabolite profile and higher liveweight gains due to backgrounding on low-level buffel grass-Desmanthus mixed pastures does not hold.

“…Because of the reduced nutritional value of this type of pasture during the fall and winter, average daily gain (ADG) from cattle is usually low. In fact, during the forage dormant season, beef steers grazing on Chihuahuan desert grasslands do not consume sufficient protein for growth ( Murillo et al, 2014 ). Growing steers are particularly susceptible to protein deficiencies because they require high levels of protein to support tissue growth.…”

Two experiments were conducted to evaluate the effects of the level of corn dry distillers grains with solubles (CDDGS) supplementation on growing performance, blood metabolites, digestion characteristics and ruminal fermentation patterns in steers grazing dormant forage. In Exp. 1, of growth performance, 120 steers (204±5 kg initial body weight [BW]) were distributed randomly into 3 groups (each of 40 steers), which were provided with the following levels of CDDGS supplement: 0%, 0.25%, or 0.50% BW. All groups of steers were grazed for 30 days in each of 3 grazing periods (March, April, and May). Approximately 1,000 ha of the land was divided with electric fencing into 3 equally sized pastures (333 ha in size). Blood samples were collected monthly from 20 steers in each grazing group for analysis of glucose (G), urea-nitrogen (UN) and non-esterified fatty acids. Final BW, average daily gain (ADG) and supplement conversion (CDDGS-C) increased with increasing levels of CDDGS supplementation (p<0.05).The CDDGS supplementation also increased the plasma G and UN concentrations (p<0.05). In Exp. 2, of digestive metabolism, 9 ruminally cannulated steers (BW = 350±3 kg) were distributed, following a completely randomized design, into groups of three in each pasture. The ruminally cannulated steers were provided the same levels of CDDGS supplementation as in the growing performance study (0%, 0.25%, and 0.50% BW), and they grazed along with the other 40 steers throughout the grazing periods. The dry matter intake, crude protein intake, neutral detergent fiber intake (NDFI), apparent digestibility of dry matter (ADDM), crude protein (ADCP) and neutral detergent fiber (ADNDF) increased with increasing levels of CDDGS supplementation (p<0.05). The ruminal degradation rates of CP (kdCP), NDF (kdNDF) and passage rate (kp) also increased with increasing levels of CDDGS supplementation (p<0.05). Ruminal ammonia nitrogen (NH3-N) and propionate concentrations also increased with increasing levels of CDDGS supplementation (p<0.05). However, acetate concentrations decreased with increasing levels of CDDGS supplementation (p<0.05). Liquid dilution rate increased with increasing levels of CDDGS supplementation but ruminal liquid volume decreased (p<0.05). On the basis of these findings, we can conclude that CDDGS supplementation enhanced the productive performance of cattle grazing native rangeland without negatively affecting forage intake, glucose and urea-nitrogen blood concentrations, ruminal degradation and ruminal fermentation patterns.

“…M. minutiflora is so widely distributed that novel attempts for its use have been evaluated: first as repellent for Rhipicephalus microplus (Canestrini, 1888) (=Boophilus microplus), a cattle tick pest in the tropics (Fernández-Ruvalcaba et al, 2003;Fernández-Ruvalcaba, Preciado-de la Torre, Cruz-Vázquez, & García-Vázquez, 2004;Muro-Castrejón, Cruz-Vázquez, Fernández-Ruvalcaba, & Torres, 2004), and later again as forage (Durán-Puga et al, 2011;Murillo-Ortiz, Mellado-Bosque, Herrera-Torres, Reyes-Estrada, & Carrete-Carreon, 2014;Ramírez et al, 2009).…”
