“…It is worth mentioning that the diet used was provided in a plan that did not limit intake, with refusals ranging between 10 and 20% of the total supplied. Nutrient intake can influence several variables, including those related to feeding behavior and blood parameters (Alba et al 2021;Brant et al 2021), so the absence of difference for these variables can be explained by the similar intake among animals of different genetic groups. The values obtained for the feeding behavior of the animals agree with those observed in several other nutritional evaluation studies of diets with animals of the Santa Inês (de Carvalho et al 2008;Pereira et al 2013) and Dorper (Brand 2000;Alba et al 2021) genetic group.…”

This study aimed to evaluate the intake, digestibility, feeding behavior, performance, carcass traits, and meat quality of feedlot Santa Inês (locally adapted breed) and Dorper (transboundary breed) lambs. Twenty non-castrated lambs were used (10 from the Santa Inês genetic group and 10 Dorper), with approximately 3 months of age and an initial body weight of 22.95 ± 2.1 kg (mean ± standard deviation), distributed in a completely randomized design. Nutrient intake and digestibility, feeding behavior, and liver metabolism enzymes were similar (P > 0.05) between genetic groups. Dry matter (DM) feeding and ruminating efficiency were higher (P < 0.05) in the Santa Inês genetic group. There was also no difference (P > 0.05) in the subjective evaluation and morphometric measurements. Genetic groups showed differences and trend to differences (P < 0.05) in performance and commercial cuts. The physicochemical characteristics, centesimal composition, and sensory attributes of the Longissimus lumborum muscle did not differ between the genetic groups (P > 0.05). The Santa Inês genetic group showed higher feeding efficiency and productive parameters when compared to Dorper lambs. Therefore, Santa Inês lambs have greater potential for meat production than Dorper lambs, when kept in the same breeding system as the feedlot.

“…Even the lambs with poor conformation can be reared under feedlots and it helps to promote the growth of muscle tissues and deposition of fat, so that desirable meat product is obtained (Van Der Merwe et al, 2020) [25] . Another advantage of feedlotting is that various by-products such as dietary dried distiller's grains solubles (DDGS) (Felix et al, 2012) [11] , soybean, molasses (Arruda et al, 2020) [3] , cottonseed cake (Brant et al, 2021) [6] , etc. can be used in feedlot diets.…”

The objective of present study was to explore the effect of feedlotting on growth parameters of crossbred lambs in temperate climate. The term "feedlotting" is basically a management practice in which frequent efforts are made by lamb producers to accomplish an unfailing supply of lamb that encounters weight and fat score as per market specifications A total of 10 crossbred lambs (around one year of age) were randomly divided in two equal groups viz. Control (CON) and treatment (FL) with 5 replicates in each group. In CON group the experimental lambs were fed by thumb rule method and FL group was fed under feedlot. To estimate the growth parameters fortnightly, a growth trial of 74 days (including 14 days adaptation) was conducted. At the end of experiment a metabolic trail of 7-days was conducted. The study indicated non-significant difference in terms of DMI, OMI, gain in body weight, ADG, FCR, digestibility coefficients of different nutrients, intake of nutrients (DDMI and TDNI), except DCPI (g/d) which differ significantly showing better results in FL group. Thus, it can be concluded from the present experiment that feedlotting had no contrary influence on the performance of crossbred lambs and can be successfully reared in feedlots under temperate climatic conditions.
