“…The LEA obtained in this study was higher than that obtained by Sousa et al (2009), 9.8 cm², for goats supplemented with feed with 157 g kg −1 CP and 670 g kg −1 TDN, and by Souza et al (2015), 6.98 cm², for goats supplemented with a diet composed of corn and soybean in the proportion of 1.5% BW. The LEA measurement is a good indicator of carcass conformation, with a positive correlation of LEA with the percentage and distribution of the muscular biomasses (Mora et al, 2015).…”

This study aimed to evaluate the performance and ingestive behavior of growing goats grazing on Tanzania guinea grass and fed diets containing 40% carnauba or tucum fruits. Twenty-one male castrated goats were distributed into three groups, one exclusively on pasture and the other two on pasture and fed diet supplemented at the level of 1.5% body weight (BW) in a completely randomized design. The intake of the supplements was obtained by difference between the amount supplied and the leftovers, with weighing performed every seven days, while pasture intake was determined using titanium dioxide (TiO 2 ) as external indicator. Ingestive behavior was evaluated for three days. The supplement containing carnauba fruit resulted in a greater intake of neutral detergent fiber (0.137 kg NDF/day), with a reduction of 8.61% in the pasture dry matter (DM) intake of goats. Associated with the intake of pasture nutrients, the tucum fruit diet met the protein (0.103 kg CP/day) and energetic (0.547 kg TDN/day) requirements of goats with intake set at 0.124 kg CP/day and 0.572 kg TDN/day, with higher weight gain (0.111 kg/day) and larger loin eye area (12.76 cm 2 ). The supplementation with fruits influenced the grazing behavior of goats, increasing the idle time by 1 h in relation to animals not supplemented. The supplementation of growing goats grazing on Tanzania guinea grass pasture with a diet containing 40% tucum fruit, in the proportion of 1.5% BW, did not meet the nutritional requirements for gain of 150 g/day; however, it met requirements for maintenance and average gain of 111 g/day. Energy supplementation reduces the grazing time of goats; thus, it is necessary to consider the level and formulation of supplements, with the possibility of increasing the stocking rate and productivity per unit area.

“…For the absolute heart weight, mean values of approximately 0.09 kg were found. Souza et al (2015) reported that the level of feeding does not influence the weight of the heart indicating that these organs maintain their integrity and are a priority in the use of nutrients, which would explain the similarity between the treatments observed in this study.…”

“…Liver weight generally reflects the metabolic rate of the animals, because this organ is closely linked to the metabolism of the animal, the size and growth of this organ is related to the greater intake of nutrients of the diet by the animal, especially protein and energy, therefore, as the intakes of CP and TDN were not influenced by diets the weight of this organ also did not vary. Bezerra et al (2010) and Souza et al (2015) observed significant differences in liver weights of grazing goats according to the level of dietary supplementation or type of diet. 042 ns G = grazing without supplementation, GJ = grazing + Jitirana hay, GJSC = grazing + Jitirana hay + spineless cactus, GM = grazing + Mororó hay, GMSC = grazing + Mororó hay + spineless cactus, NDF = neutral detergent fiber, NFC = non-fibrous carbohydrates, TDN = total digestible nutrients, TOTL = Tongue + Oesophagus + Trachea + Lungs; BWS = body weight at slaughter; EBW = empty body weight, *SEM = Standard error of the mean; Means followed by the same letter in the line do not differ by the Tukey test at the 5% probability level.…”

“…According to Brand, Van Der Merwe, Swart, and Hoffman (2019), goats have a greater physiological ability to deposit fat around the internal organs, constituting, in one aspect, an energy reserve for the animal during the dry season. The deposited fat is the non-carcass component that presents greater variation as a function of the nutritional level ingested (Asizua et al, 2014;Souza et al, 2015;Luz et al, 2017). Although it's over accumulation is not desired.…”

“…The level of dietary supplementation, type of food and energy level of the diets may influence the weights and yields of the non-constituent components of the carcass in small ruminants (Bezerra et al, 2010;Souza et al, 2015;Ribeiro et al, 2017). Thus, the objective of this work was to evaluate the weights and yields of the non-carcass components of goats submitted to grazing in the Caatinga supplemented with spineless cactus and native plants.…”

The objective of this study was to evaluate non-carcass components of goats submitted to grazing in the Caatinga rangeland and supplemented with spineless cactus (Nopalea cochelinifera Salm Dick), Jitirana hay (Merremia aegyptia L. Urban) and Mororó hay (Bauhinia cheilanta Bong Stend). Thirty male goats (castrated), with no defined breed, with an initial mean body weight of 19 ± 0.35 kg and approximately 90 days of age were used. The treatments consisted of grazing without supplementation (GWS), grazing + Jitirana hay (GJ); grazing + Jitirana hay + spineless cactus (GJSC); grazing + Mororó hay (GM); grazing + Mororó hay + spineless cactus (GMSC). The means of the variables were tested by Tukey's test at 5% probability. The goats fed GWS, GJSC, GM and GMSC presented higher weights and yields of the diaphragm, and the spleen weight (p < 0.05). The highest yield of omasum (p < 0.05) occurred with goats fed GJ treatment. There were treatments (p < 0.05) on omental fat weight and leg yield, with the highest values for goats, fed GWS, GJSC, GM, and GMSC. The "Buchada" EBW-1 yield was higher (p < 0.05) for animals fed GWS. Feeding supplementation of goats grazing in the Caatinga had few influences on weights and yields of non-carcass components.

This study evaluated the performance and carcass characteristics of lambs fed diets with increasing levels of Mimosa tenuiflora (Willd.) hay replacing Buffel grass (Cenchrus ciliaris). Twenty-eight Santa Inês male lambs with an average body weight (BW) of 20.3 ± 1.49 kg(mean ± SD) were allocated in individual stalls and distributed in a completely random design with four treatments (0, 20, 40, and 60 g/100 g total DM M. tenuiflora hay replacing Buffel grass hay in diet) with seven replications. M. tenuiflora hay at the level of 20% dry matter (DM) total replacing Buffel grass hay increased final weight (P = 0.006), total weight gain (P < 0.001), average daily weight gain (ADWG; P < 0.001), DM intake (P < 0.001), and feed efficiency (P < 0.001). Intake of crude protein, NDF, ADF, ash, ether extract, total and non-fibrous carbohydrates, and total digestible nutrients presented a positive quadratic effect with M. tenuiflora hay replacing Buffel grass hay and 40 g/100 g total DM level presented greater intake. There were positive quadratic effects by M. tenuiflora hay inclusion at 20 g/100 g total DM level on slaughtering weight (P = 0.005), hot carcass weight (P = 0.002), cold carcass weight (P = 0.002), empty body weight (P = 0.001), hot carcass yield (P = 0.002), cold carcass yield (P = 0.003), and increase linear on biological yield (P = 0.003). There was no influence on cooling weight loss (P = 0.284). M. tenuiflora hay may be included in lamb diets at amounts up to 20 g/100 g total DM substitution of Buffel grass hay because increase in the nutrients intake, growth performance, and carcass characteristics.
