“…In a meta-analytical approach evaluating zebu animals grazing Urochloa spp. with mineral and energy/protein supplementation [ 67 ], the DMI results were lower than those found in this study, with the average performance of animals consuming only mineral supplementation being similar to those found in the DEG treatment. In addition, energy/protein supplement consumption was around 1 kg per animal [ 67 ], a value above that found in the DEG and REC treatments.…”

In this study, we evaluate the effects of intercropping pigeon pea (Cajanus cajan (L.) Millsp.) with tropical pastures for feeding Nellore cattle and compared animal performance and enteric CH4 emissions with other pasture-based systems during the dry and rainy seasons of 2021. Thirty-six Nellore steers (with a body weight of 221 ± 7 kg and an age of 15–16 months) were randomly distributed in three treatments with three replicates (in paddocks of 1.5 hectares each): (1) a degraded pasture of Urochloa spp. (DEG); (2) a recovered and fertilized pasture of Urochloa spp. (REC); and (3) pigeon pea intercropped with Urochloa spp. (MIX). Enteric CH4 emissions were estimated using the sulfur hexafluoride (SF6) tracer gas technique, and dry matter intake (DMI) was determined using internal (iNDF) and external (TiO2) markers. Forages were collected by hand plucking after observations of ingestive behavior, and feces was collected after voluntary defecation. The proportion of grass and legume intake was estimated by C stable isotopes, and the forage nutritional quality was determined, while animal performance was monitored monthly, and the stocking rate was adjusted by the “put and take” technique. The results indicated that intercropping pigeon pea with tropical grasses is an interesting strategy for sustainable livestock production based on pastures. The MIX treatment was able to meet the nutritional requirements of the animals, which presented higher performance. In addition, there was a reduction in CH4 emissions up to 70% when expressed per average daily weight gain in comparison to the DEG treatment.

“…Although the supply of pdDM was reduced, the offered forage was greater than recommended for zebu (40-50 g/kg of body weight) to express the potential weight gain (Paulino et al 2008). Also, in this study, the forage indigestible neutral detergent fiber was lower than 270 g/kg DM (Almeida et al 2022), which indicate good forage conditions to maximize the average daily gain in the tropics.…”

The effects of higher supplementation levels for young Nellore heifers fed tropical forages including their influence on puberty, need to be understood. This study investigated the influence of high and moderate supplementation levels on puberty onset and the productive performance of Nellore heifers. Thirty-six Nellore heifers (225 + 3.52 kg) were used in a completely randomized design, with three treatments: (I) no concentrate (control); (II) concentrate supplement at 4 g/kg body weight (BW); (III) concentrate supplement at 8 g/kg BW. Increased supplement level led to a linear increase in average daily gain (P < 0.05). The high supplementation level (8 g/kg BW) had the highest proportion of corpus luteum presence (82% of heifers), compared to the 4 g/kg BW treatment group (67%) and the control group (33%; P < 0.05). Our findings indicate that providing a high level of energy supplementation to Nellore heifers for approximately 100 d improves performance and increases the proportion of heifers that reach puberty

“…Studies in tropical conditions indicate that the productive response of grazing cattle to protein supplementation is inversely related to the nutritional value of the forage (Almeida et al, 2022;Sousa et al, 2022). In association, there is a lot of evidence that supplementation of beef cows in the prepartum period, which coincides with the dry season, is more important than in the postpartum period, and this response is attributed to the physiological conditions inherent to the phase (Hess et al, 2005; Diskin and Kenny., 2016).…”

We objective was to understand the changes in nutritional characteristics and performance of grazing Nellore cows during the peripartum receiving or not supplementation. Forty multiparous cows were used, divided into two treatments: CON - mineral mixture and SUP – protein supplementation. Digestibility trial was performed (-45,-30,-15, + 20, +40; days relative to calving). The average daily gain (ADG) pre and postpartum of the cows were measured and, in gestational and maternal tissues in the prepartum, in addition of body condition score (BCS). The calves were weighed at birth and at 30 days of age. There was an effect of treatment and period (P ≤ 0.10) for dry matter, organic matter and crude protein intake, while forage intake was similar (P ≥ 0.10), but with a period effect (P ≤ 0.10). There was 14.37% decrease in dry matter intake from day − 30 to day − 15 of prepartum. In the postpartum period, at 20 days of lactation, there was increase of 72.66% in relation to the period − 15. There was interaction between period and treatment for all digestibilities (P ≤ 0.10). No differences were observed in postpartum ADG (P ≥ 0.10), BCS at calving and postpartum (P ≥ 0.10). However, higher total ADG and in maternal tissues (P ≤ 0.10) were observed on supplemented animals, but with ADG in gestational tissues similar (P ≥ 0.10). It is concluded that there is a decrease in voluntary intake in grazing pregnant cows close to parturition and greater performance of animals supplemented in prepartum.
