“…BARGO et al (2003) suggested that appropriate values for animals fed solely with pastures range from 3 up to 5 times more than that estimated for dry matter intake, and 2.5 times higher when animals receive supplements. Furthermore, FA values from experiments analyzed in the present study were within the range indicated by GRAMINHO et al (2019), from 6 to 12 kg of DM per 100 kg of BW for ryegrass management, without jeopardizing foliar tissue fluxes and efficiency of pasture use. The sum of the average supplement intake and forage allowance totaled 10 kg of DM per 100 kg of BW, similar to the forage allowance of heifers maintained only on pastures.…”

Pooled data analysis is an analytical method that combines results from multiple studies. This technique provides a more robust estimate of the effects of an investigation. We performed a database analysis from seventeen experiments developed at Federal University of Santa Maria, Rio Grande do Sul state, Brazil, between 1999 and 2017 to characterize individual performance per area and stocking rate with or without supplementation of replacement heifers grazing winter pastures. Data were separated into two groups: with and without energy supplement provision, and into five subgroups based on supplement levels. Heifers from both groups were maintained under similar forage biomass and leaf blade allowance. Statistical analyses were run on R software using a ‘meta’ package. Supplement supply increased average daily gain and gain of body condition scores by 11.1% and 20.0%, respectively. Supplement levels higher than 1.2% of body weight resulted in higher weight gain per area, with the stocking rate increasing with higher supplement levels.

“…In southern Brazil, annual ryegrass (Lolium multiflorum Lam.) has great importance in livestock systems, in which the ryegrass is a spring-winter growth, in which is stands out for having high nutritional species value and can be used in the efficient and economically viable production of lambs, which are animals with high nutritional requirements (GRAMINHO et al, 2019). This is due to a number of characteristics of this grass including high forage yield, good quality, good nutritional value, adaptation to different types of soil, and natural reseeding capacity (CONTERATO et al, 2016;FONTOURA et al, 2020).…”

Annual ryegrass is one of the species that best meets the needs of the farmers in south Brazil during the winter. Many of these cultivars can be found in the market. However, in some cases information on their actual adaptation to each climate situation or production system is unavailable. The present study aimed to evaluate the productive performance of diploid and tetraploid cultivars of annual ryegrass under grazing. The experiment was carried out in the municipality of Pato Branco, State of Paraná (PR), Brazil. The experimental design was a randomized complete block design with 4 replications. The following were the cultivars observed in this study: LE 284, Camaro, Bakarat, Estações, Ponteio and Nibbio (diploids; 2n), Winter Star, KLM 138, Scorpio, Titan, Barjumbo, and Potro (tetraploids; 4n). Mob grazing was used with an entry height of 25 cm and an exit height of 10 cm. It was noted that the cultivars that presented the longest period of pasture use were those that produced the greatest amount of forage. For all cultivars evaluated, the greatest accumulations of forage occurred between August, September, and October. Cultivars Winter Star (4n) and Escórpio (4n) stood out as they yielded the largest forage production. On average, tetraploid cultivars are more productive than diploid cultivars.
