“…The nutrient supply from the concentrate supplementation should not completely meet the requirements of animals, thus avoiding physiological energetic limitation by the chemostatic effect in the medial hypothalamus (satiety center), and the pasture should meet other needs (Ferdous et al, 2012). Setting the supplement at 1.5% BW is compatible with the research carried out with goats supplemented in the proportion of 1 to 1.5% BW with corn and soybean meal in pasture systems (Bezerra et al, 2010;Adami et al, 2013).…”

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.

“…The internal fat is highly variable and can be influenced by genotype (Rodrigues et al, 2013), nutrition (Bezerra et al, 2010), age, slaughter weight (Al-Owaimer et al, 2013), physiological condition, and physical activities (Solaiman et al, 2011). Higher visceral fat deposition can be explained by its more intense vascularization.…”

Performance and carcass traits of Moxotó growing goats supplemented on native pasture under semiarid conditions

et al. 2014

-The objective of the present study was to assess the growth performance and carcass traits of Moxotó goat kids fed different levels concentrate (supplement) (SL) on native pasture under semiarid conditions in Brazil. Thirty-two castrated kids (15.7±0.78 kg initial BW) were allocated randomly to one of the four SL (treatment groups: 0, 5, 10 and 15 g/kg BW). When the animals of treatment group 15 g/kg BW reached 25 kg BW, the animals in the other treatments groups were also slaughtered. Therefore, the animals belonging to the 0, 5, 10 and 15 g/kg of BW were finished with 18.40, 21.04, 22.94 and 25.74 kg of BW, respectively. The concentrate supplementation positively influenced the performance and the carcass traits of animals, providing higher feed intake and thus greater weight gain. The results of cold carcass yields were 405.9, 427.0, 449.1 and 462.9 g/kg of SBW for 0, 5, 10 and 15 g/kg BW, respectively. The weight of the different commercial cuts, (neck, ribs, shoulder, loin and leg) increased linearly as the SL increased; however the yields of the carcass cuts were not influenced, except for the shoulder. Overall, the distribution of non-carcass fat increased as SL increased, with the exception of mesenteric fat yield, which was not influenced. The use of concentrate supplementation to Moxotó goats under grazing conditions on native rangelands of the Brazilian semiarid improves the performance of animals and carcass yield, but does not affect the yields of commercial cuts of Moxotó growing goats.

“…Carvalho Junior et al (2009), when evaluating carcass characteristics of crossbred (Boer × UB) goats subjected to three supplementation levels concluded that animals supplemented with up to 1% body weight had heavier carcass and commercial cuts. However, Bezerra et al (2010) observed that protein-energy supplementation to UB kids in the Caatinga during the dry season provided animals with higher body weight at slaughter and increased absolute weights of organs and viscera. Thus, the use of supplementation during the dry season is considered a good alternative to provide, in quantity and quality, nutrients that native pasture cannot supply and thus, increase the productivity of animals in order to meet market demands.…”

-The objective of this study was to evaluate morphometric measures, carcass yields, absolute weights and yields of commercial cuts of carcass of kids with no defined breed. Eighteen castrated male goats, with average weight of 15 kg were used. The experimental period lasted 105 days. The experimental design was completely randomized; animals were allocated to three treatments: free grazing without supplementation; restricted grazing without supplementation and free grazing with supplementation. Animals were supplemented (1% of body weight) with forage cactus (Opuntia ficus -indica, Mill) and soybean meal (Glycine max). The feeding consisted of continuous grazing on caatinga. Supplemented animals had higher live slaughter weight and body score, and consequently higher morphometric measures in vivo and in carcasses. The supplementation provided carcasses with higher body weight and body score. For yields of carcass, there was no difference between treatments restricted grazing and grazing with supplementation; supplementation provided carcasses with higher yields. Supplemented animals had higher absolute weights for commercial cuts. Supplementation of grazing goats raised in the caatinga provides animals with higher body weight at slaughter, greater morphometric measures in vivo and in carcass and better body conformation. Therefore, for supplementation, the level used in this experiment is a good alternative in the creation of small ruminants during the dry period in the semi-arid region.
