“…Table 6 -Hepatic metabolite of lambs with levels ALL G-Rich ® in the concentrate. According to Dallago et al (2011), elevated concentrations of alkaline phosphatase, gammaglutamyl transferase and aspartate aminotransferase are related to hepatic injuries. When hepatic injuries happen, hepatocellular damage overflows the hepatocytes by raising their serum concentration.…”

The purpose of this study was to evaluate the effects of docosahexaenoic in the concentrated acid on intake, digestibility, metabolic profile and ingestive behavior of lambs diets. Five crossbred Dorper x Santa Inês lambs with initial age and body weight average of six months and 33 kg, respectively, were used in the trial. The animals were assigned into a 5×5 Latin square design and they received one of the following treatments: 0, 1.5, 3, 4.5 and 6 % of microalgal product (Aurantiochytrium limacinum algae) or ALL-G Rich® in the concentrate. The diets were composed of corn silage and concentrate offered twice daily. During the experimental period, feed, water, feces, blood, and urine were sampled to calculate the intake and digestibility and to characterize the metabolic profile. The ingestive behavior was measured during 24 hours on the last day each experimental period. The time spent on feeding, ruminating and idle activities was measured. Regression analyses were performed considering 5 % of significance. There were no difference on nutrients intake, digestibility, and ingestive behavior with the inclusion of ALL-G Rich® in the diet (p>0.05). There was a significant effect on serum concentrations of cholesterol, low density lipoprotein, alkaline phosphatase and gammaglutamyl transferase, however, all metabolites remained within the range recommended for the animal category. Thus, ALL-G Rich® can be used up to 6% in the concentrate, on dry matter basis, of lambs diet without affect intake, digestibility, metabolic profile, and ingestive behavior.

“…Although there has been an evolution in the number of inputs specific to the activity, there are still some basic items that are insufficient and inadequate to fully meet economic needs of the farmer in Brazil. For example, some types of feeds, mineral supplements and even machinery and equipment, still show questionable effectiveness and cost/benefit [16].…”

“…Currently, Brazil has the 8th largest flock worldwide with an estimated flock size of approximately 16.05 million head [2]. The Northeast region has 56% of the Brazilian sheep while the South has 32% and Southeast is third with 3.4% [3].…”

Abstract:Sheep production is present on all continents and has been practiced in Brazil since the colonization. In this study, the multitemporal dynamics of sheep production in Brazil is examined using official government data (Brazilian Institute for Geography and Statistics-IBGE) from 1976 to 2010. Maps of flock growth rates and growth acceleration maps by municipality were elaborated. The Southern states are seen to show a reduction in production mainly due to the wool crisis in the 1970s and 80s. The Northeast is seen to be important for meat production. More recently, centerwest and northern states have shown an increase in growth rates but this is still incipient. The maps of growth, acceleration and midpoint for sheep production showed a noticeable return to an increase in production in the South in recent years. The midpoint of production flow was in the northeast direction, which has stagnated. There was great dynamics in sheep production over the whole Brazilian territory, which affected supply chains due to the expansion of domestic and

“…Pechov and Pavlata (2007) informed that Cr supplementation in an in vitro animal tissue improved glucose oxidation, resulting in CO 2 +H 2 O formation, improving glycogenesis, and converting glucose to lipid which improved glucose utilization. Dallago et al (2011) stated that supplementing 250-375 ppm chromium per day did not affect total ruminal protozoa (15-16 unit/mm3 ruminal fluid) and normal ruminal pH (6,49 ± 0,28). However, supplementing 500 ppm chromium per day could significantly decrease total ruminal protozoa 21-day post-treatment into 6-9 unit/mm3 ruminal fluid.…”

This research investigated the effect of supplementing garlic powder and organic micromineral Cr in feed on rumination time and frequency in Ettawah goat (PE). The research was conducted in Gunung Tugel Farm in Patikraja and the Laboratory of Feed Technology in Faculty of Animal Science, Universitas Jenderal Soedirman, Purwokerto, Central Java. This study used 18 male PE aged 1-1.5 years and weighed 18.62 – 22.69 kg. The feed consisted of 60% concentrate and 40% forage (field grass). Other materials included drinking water, 250 ppm garlic powder (Allium sativum), 1.5 ppm organic chromium mineral and eight CCTV camera. The observed parameters were rumination time and frequency. An in vivo experiment in a Completely Randomised Design (CRD) administered three treatments and six replicates, namely R0: control (basal feed); R1: basal feed + 250 ppm garlic powder; and R2: basal feed + 250 ppm garlic powder + 1.5 ppm organic Cr. The result demonstrated a significantly different effect of garlic powder and organic Cr micromineral supplement on rumination time across treatments, i.e. 404 ± 19.6; 382 ± 19.04 and 351 ± 13.87 min/day, respectively, or 379 min/day on average. Rumination frequency was not significantly different across R0, R1, and R2 namely 360 ± 24.03; 359 ± 30.13 and 342 ± 21.10 times/day, respectively. Conclusively, garlic powder and organic Cr micromineral significantly affected rumination time, but not significantly affected rumination frequency of PE goat.
