“…However, the LCI did not differ between treatments and averaged 0.65 kg cm -1 (Table 1). The CCI values obtained were higher than those reported in the literature for Boer crossbred goats, ranging from 0.18 to 0.26 kg cm -1 (Dias et al, 2016;Salles et al, 2013). The LCI was inferior to that observed by Salles et al (2013), with a range from 0.41 to 0.44 kg cm -1 .…”

“…WLC was influenced by sex, where male values (1.20%) were lower than females (2.26%). These results were lower and better than those observed in the carcasses of crossbred Boer goats of 3.03% by Dias, Silveira, Lançanova, Hill and Moletta (2016). Muscle surface moisture losses during carcass cooling are mainly dependent on fat coverage, due to the greater protection afforded to the carcass (Goetsch, Merkel, & Gipson, 2011).…”

The objective of this study was to evaluate the influence of live yeast (Saccharomyces cerevisiae var. boulardii) on the quantitative and qualitative characteristics of the shoulder and loin of Boer x Saanen crossbred goat kids. Twenty-seven carcasses were used, 13 females and 14 uncastrated males with an average age of 192 days, weighing 30.76 kg, distributed in a completely randomised design using a 2 x 2 factorial arrangement (diet and sex). The yeast was added to the feed before pelletising in a proportion of 0.050 g/kg dry matter (DM). When the goats reached an average of 30 kg of live weight, they were slaughtered. No effects of live yeast on quantitative carcass and qualitative characteristics of shoulder and loin were observed. Regarding sex, males had higher slaughter weights (31.73 kg), empty carcass weight (27.98 kg), hot carcass weight (14.39 kg), cold carcass weight (14.22 kg), higher carcass compactness index (0.28 kg/cm), lower slaughter age (176 days) and lower cooling loss (1.20%). For the cut yields, females presented a higher loin yield (11.55%) and males presented a higher neck yield (6.84%). In the shoulder, males presented a higher proportion of bone (18.58%), while females presented a higher proportion of fat (17.09%) and muscle:bone (3.47). In the loin, females showed higher fat deposition (19.54%) in relation to males. The inclusion of yeast Saccharomyces cerevisiae var. boulardii in the crossbred goat kids’ diet did not generate differences in the quantitative and qualitative characteristics of the shoulder and loin.

“…A number of studies have been carried out on the effect of glycerol on production parameters when administered to dairy cows [ 33 , 53 , 66 ], beef cattle [ 43 , 55 , 67 ], goats [ 68 ], and lambs [ 69 ]. In sheep studies, it has been established that a positive effect on growth rates, feeding behavior, and blood metabolites is achieved with no higher than 4.7% DM [ 69 ].…”

The aim of this paper is to review and systematize the current state of knowledge on glycol metabolism in cattle. Glycerol, derived from biodiesel production, must be purified in order to be a useful product for feeding livestock. The use of glycerol in the feeding of ruminants can be justified for several reasons: (i) it is a source of energy in the ration, (ii) it is a glucogenic precursor, and (iii) it may have an effect on milk composition. The high energy value of glycerol provides the opportunity to use this raw material as a partial grain substitute in cattle feed rations. Dietary supplementation of glycerol is associated with increased propionate, butyrate, valerate, and isovalerate concentrations in the rumen. Glycerol can be used at up to 10%–15% of the dietary dry matter (DM) and is well-established as a treatment for ketosis in cows. Glycerol increases plasma glucose and may reduce non-esterified fatty acids and β-hydroxybutyrate levels. The use of glycerol does not have a clear effect on DM intake, milk yield, or milk composition. However, some authors have reported an increase in milk yield after glycerol supplementation associated with decreased milk fat concentration. It is also possible that the concentration in the milk of odd-chain fatty acids and cis-9, trans-11 conjugated linoleic acid may increase after glycerol application.

“…In addition, the higher final weight was more likely related to high fat deposition which is concomitant with the biochemical change in the reticulorumen of the goat. Glycerin as a gluconeogenic precursor [20] is converted into propionate in the rumen [9,21] which accelerated the metabolism of pyruvate in the adipose tissue [22] and resulted in a higher deposition of fat in subcutaneous and visceral parts [5].…”

The effects of feeding concentrate diet containing crude glycerin supplementation and castration on carcass composition and meat quality of Thai Native x Anglo-Nubian (TN-AN) goats were investigated. Twenty TN-AN goats at the age of 12 months old with 24.75±1.33 kg initial live weight were allotted into a 2x2 factorial arrangement in completely randomized design when factor A was assigned for sexes (intact and castrated male) and factor B was assigned for 2 types of concentrate diet (control diet and diet supplemented with 10 % crude glycerin). Goats were intensively raised in individual pens with ad libitum water and Atratum grass (Paspalum atratum), while 2 % of concentrate diets was provided. After 90 days of feeding, 3 goats from each treatment combination were randomly sampled and sacrificed for further examination. From the study, castrated male goats had significantly higher slaughter and carcass weight, carcass fat percentage and chemical fat percentage than those of the intact males (P < 0.01). In addition, muscle from castrated male goats was more tender and lighter in color as compared with intact male goats (P < 0.01). Goats receiving a diet with extra glycerin had significantly higher weight at slaughter, warm carcass weight, carcass fat, and chemical fat percentages than those on the control diet. Therefore, it could be concluded that feeding goats with a diet of 10 % supplementary glycerin and castration could lead to better slaughter and warm weight, whereas a higher fat content in the carcass and muscle are observed.
