The objective of this study was to evaluate the effects partial replacement soybean oil by fish on dry matter intake (DMI), growth, carcass characteristics, and meat fatty acid profile feedlot lambs. Fifty Santa Ines male lambs with 17.1 ± 2.8 initial body weight (BW) were individually penned used in a randomized complete block design 10 blocks 5 treatments. Dietary treatments, (DM) basis, consisted of: (1) control diet (CONT) 10:90 forage concentrate ratio, (2) supplemented 40 g/kg (0FO),...
Nelore heifers usually begin their reproductive life at ⩾24 months of age mainly due to suboptimal nutritional conditions and genetics. This study aimed determine the effect expected progeny difference (EPD) for first calving average daily gain (ADG) on puberty in (Bos taurus indicus) heifers. A total 58 weaned (initial BW=174±6 kg; age=9±1 months) were allocated into 28 feedlot pens. Heifers born from four sires, which two had low EPD (L; n=33) high (H; n=25). Then, each randomly assigned...
Poor-quality roughages are widely used as fiber sources in concentrate-based diets for ruminants. Because roughage quality is associated with the efficiency of energy use forage-based diets, objective this study was to determine whether differing source could change requirements growing lambs. Eighty-four 1/2 Dorper × Santa Inês ram lambs (18.0 ± 3.3 kg BW) were individually penned and divided into 2 groups according primary dietary roughage: low-quality (LQR; sugarcane bagasse) or...
This experiment evaluated the effects of temperament on physiological, productive, and reproductive responses in Bos indicus beef cows. A total 953 lactating, multiparous, non-pregnant Nelore cows (age = 99 ± 2 mo; days post-partum 51.4 0.3 d; BCS 5.34 0.04; BW 430 kg) were allocated into 8 groups approximately 120 each. Groups assigned to an estrus synchronization + timed-AI protocol at beginning breeding season. Concurrently with AI, blood samples collected, hair clipped from tail switch,...
Blanks (flasks without substrate containing only inoculum and medium) are used in vitro to correct for gas, CH4 residual organic matter (OM) fermented inoculum. However inclusion of rumen fermentation modifiers may affect OM the Thus, data correction using blanks that lack additives result inaccurate adjustment background fermentation. Our objective was evaluate impacts additive (i.e., specific blanks) or on estimation net gas production. We semi-automatic production technique including...
Abstract The aim of the present study was to evaluate inclusion narasin, salinomycin, or flavomycin for 140 d on ruminal fermentation parameters, apparent nutrient digestibility, and performance Nellore cattle offered a forage-based diet. In experiment 1, 32 rumen-cannulated Bos indicus steers [initial body weight (BW) = 220 ± 12.6 kg] were assigned individual pens in randomized complete block design according their initial shrunk BW. Within block, animals randomly 1 4 treatments: (1) diet...
Differences among dietary protein levels suggested in the literature point out to need for better evaluation of requirements growing lambs, raised drylot on a high-concentrate diet. This study evaluates influence crude (CP) high concentrate diets performance and carcass traits ram confined 56 days. Forty eight (48) Santa Ines lambs (initial body weight 18.4 ± 0.4 kg; 86 2 days old) were fed 4 experimental containing 14, 16, 18 or 20% CP, completely randomized block design. Diets consisted...
Objetivou-se avaliar os efeitos do fornecimento de polpa cítrica na dieta sobre as características carcaça e a qualidade da carne cordeiros em confinamento. Utilizaram-se 32 Santa Inês distribuídos delineamento blocos completos casualizados com quatro tratamentos oito repetições, quais foram definidos pelo peso pela idade dos animais no início experimento desempenho. Os alimentados rações contendo 90% concentrado (milho moído e/ou cítrica, farelo soja minerais) 10% feno coastcross (Cynodon...
The objectives of this experiment were to determine the effects replacing ground corn with soybean hulls (SH) in high-concentrate diets on growth (56-d period), carcass characteristics, and eating behavior feedlot lambs. Sixty-four Santa Inês ram lambs (18.3 ± 2.8 kg BW 69 5 d age) assigned a randomized complete block design 8 blocks 4 diets. control diet contained 10% coastcross (Cynodon sp.) hay, 70% corn, no SH (SH0) dietary DM. In remaining diets, replaced at rate 15 (SH15), 30 (SH30),...
This study evaluated the effects of narasin on intake and rumen fermentation characteristics Bos indicus steers offered a high-forage diet for 140 d. On day 0 study, 30 rumen-fistulated Nellore [initial body weight (BW) = 281 ± 21 kg] were assigned to individual pens in randomized complete block design according their initial BW. Animals randomly 1 3 treatments: 1) forage-based without (CONT; n 10), 2) CONT plus 13 ppm (13NAR; 3) 20 (20NAR; 10). The forage used was Tifton-85 (Cynodon...
O objetivo deste trabalho foi avaliar a influência de grãos soja (GS) no desempenho, características e rendimento cortes carcaça cordeiros confinados. Sessenta quatro Santa Inês, com peso vivo inicial 19,5±0,19 kg 75±2 dias idade, foram distribuídos em blocos ao acaso acordo o idade início do experimento. Os GS participaram 0, 7, 14 21% na matéria seca (MS) das rações isonitrogenadas experimentais. consumo MS (1,1, 1,0, 0,9 por dia), proteína bruta (199,2, 181,5, 179,0 175,2 g dia) ganho...
