“…In our experimental conditions, after 1 year of intensive feeding our results suggested that in Creole kids, muscle mass reached upper levels but intramuscular fat deposits were not at maximum. The DMI relative to the metabolic weight (70.5-72.0 g kg LW-0.75) of the Creole kids was in accordance with the values reported for other tropical breeds fed under semi-intensive conditions (71 and 80 g kg LW-0.75) (26,29,30). In accordance with these results and the curvilinear trend observed with a threshold value for the supplemented kids, we concluded that the fattening growth potential of Creole goats would be 85 g d −1 .…”

“…In accordance with these results and the curvilinear trend observed with a threshold value for the supplemented kids, we concluded that the fattening growth potential of Creole goats would be 85 g d −1 . It has been shown in other tropical goats that higher values (92-148 g d −1 ) could be reached with high-energy diets (29)(30)(31)(32). However, the relative growth rate (i.e., the ratio of fattening ADG to birth weight) reached 4.5% for this Creole breed and were very similar to those of Omani and crossbred Boer goats (4.1 and 4.3%, respectively) (33,34).…”

The objective of this study was to evaluate the effects of diet and age on finishing performances and carcass characteristics of male Creole goats. A total of 91 weaned male Creole kids [84 days old ± 7 days, 9.2 kg live weight (LW) ± 0.5 kg] were randomly allocated in a 2 × 3 experimental design. The animals were fed individually with two diets: C0: a 28-day-old Digitaria decubens grass alone, or C50: the same grass plus a commercial concentrate (50% of the total diet) and then slaughtered at 7, 11, or 15 months of age. Significant feeding regimen and age at slaughter effects were observed on the goat carcass characteristics. The addition of concentrate improved the average daily gain (ADG), the dressing percentage, and the conformation score (1–5 scale) from 46 to 88 g/day, 52.8 to 62.4%, and 2.2 to 4.9, respectively. Moreover, carcasses of the C0 group appeared lean with less developed fat than the C50 group and lighter than visceral fat. The meat color was significantly more affected by diet than age. Our data suggested that the production of heavy carcasses with low proportions of fat in the meat is possible in this local breed. The valorization of such a forage feeding system until 11 months of age or with the addition of concentrate from 7 to 11 months of age should be evaluated economically.

“…The nutrients intake is one of the primary factors in the feed conversion into animal product, so that the intake of digestible DM is more affected by the DMI than by the digestibility itself [ 26 ]. In this study, although animals finished in pasture had higher TDMI, the animal performance was lower for this finishing system when compared to feedlot.…”

The study aimed to evaluate the effect of replacing cottonseed meal by dried distiller’s grains (DDG) in terms of efficiency in the productive aspects of beef cattle finishing in pasture versus feedlot. The experiment was conducted in a completely randomized design in a 2 × 3 factorial arrangement, with two production systems (pasture versus feedlot) and three supplements: CM, conventional supplement with cottonseed meal (CM) as a protein source; 50DDG: supplement with 50% replacement of CM by DDG; and 100DDG: 100% replacement. The effect of replacing CM by DDG on dry matter and nutrients intake and nutrients digestibility depends on the finishing system (p < 0.05). While in the pasture system animal consumed more nutrients in the CM, a greater intake was observed in the 100DDG in feedlot. The nutrients digestibility was lower in the pasture (p < 0.05). Animal performance and final body weight were higher in the feedlot (p < 0.0001), with averages of 1.57 kg/d and 566 kg of final body weight (FBW) for feedlot, and 0.99 kg/d and 504 kg FBW for pasture. The use of DDG does not change the animal performance finished in pasture or feedlot, and it is a viable alternative to replace conventional supplements in finishing phase in both systems in tropical environment.

“…The sex effect on animal DMI is well studied and it is known that it influences voluntary intake of cattle, and, in certain conditions, sheep and goats [ 26 – 28 ]. In the present study, the effect of sex class (females, and non-castrated or castrated males) on the coefficients of all equations was evaluated, but it was not significant.…”

‘Meta-analysis of dry matter intake and neutral detergent fiber intake of hair sheep raised in tropical areas’

Inadequate estimates of fiber and dry matter intake of sheep raised in tropical conditions may explain part of the inefficiency of those production systems. Therefore, we aimed to estimate dry matter intake (DMI) and neutral detergent fiber intake (NDFI) of hair sheep raised under tropical conditions. A meta-analysis of 61 independent performance experiments, comprising a total of 413 experimental units (treatment means or animals), was performed. Trials were conducted in tropical conditions, using hair sheep in growing and finishing phases and endowed with the following information: neutral detergent fiber (NDF) in diet, initial and final body weight (BW), average daily gain (ADG), DMI and NDFI of treatment means (51 studies) or individual data (10 studies). Data on organic matter and NDF digestibilities were collected to estimate D-value (Dv) and B-value (Bv) (20 and 33 studies, respectively). The equations obtained were: DMI(g/day)=50.5773±71.0504+1.4423±0.1704×ADG+28.4406±2.9697×BW;DMI(g/kgBW)=42.1088±4.7298+0.05516±0.009427×ADG−0.4402±0.1865×BW;NDFI(g/day)=−52.2187±47.7718+1.3773±0.2292×NDF(g/kgDM)−0.0007±0.0002×NDF(g/kgDM)2. DMI (g/kg BW) as a function of Dv (g/kg DM) revealed a quadratic relationship, whose point of maximum DMI (38.69 g/kg BW) was obtained at 634.1 g/kg DM Dv. On the other hand, DMI decreased linearly as Bv (g/kg DM) increased. In conclusion, equations to predict DMI from BW and ADG as well to predict NDFI from dietary NDF were fitted with great accuracy and are recommended for hair sheep raised in tropical regions. DMI values were, in general, greater than those reported by the NRC, AFRC and INRA systems, which may be a reflection of the sheep breeds used in this study. Using Dv and Bv concepts was satisfactory to describe an integrated mechanism between metabolic and bulking regulation of DMI in sheep.
