“…Mean DM conversion was approximately 6.2 kg of DM for 1 kg of BW gain and may be attributed to the genetic quality of animals (½ Angus vs ½ Nellore), their sexual condition (bulls) and the diet's high energy density (75% TDN). Usually, crossbred bulls fed on a high energy density diet have feed conversion of 7 kg of DM intake for 1 kg of BW gain (Fugita et al, 2012;Maggioni et al, 2009). …”

The effect of corn substitution by glycerine and essential oils on animal performance, apparent digestibility and red and white blood cells of crossbred bulls finished in feedlot was evaluated. Thirty bulls with average weight of 311±28.8 kg and 22±2 month-old were allocated in three diets: CON (without glycerine or essential oils), GLY (with glycerine) and GEO (with glycerine and essential oils). The bulls were fed a diet of sorghum silage, cracked corn, soybean meal, urea, limestone and mineral salt. Three grams of cashew and castor oil/animal/day were included in GEO diet. Animals were kept in feedlot for 115 days and slaughtered at average weight of 467±40.6 kg. No differences (P<0.05) among diets regarding final body weight, average daily gain and feed conversion were reported. Ether extract intake was higher (P<0.05) in CON diet compared to the others. Dry matter, organic matter and crude protein digestibility was higher (P<0.05) in GLY diet compared to CON. Acid detergent fibre digestibility was higher (P<0.05) in CON compared to GLY diet. Nonfibrous carbohydrate, fibrous carbohydrate and ether extract digestibility were similar (P>0.05) among diets. No effect of glycerine and essential oil addition on total blood cholesterol, triglycerides, haemogram, leukogram and plasmatic proteins was observed. Corn replacement by glycerine and essential oils addition did not affect (P>0.05) carcass weight, dressing and conformation, carcass length and cushion thickness.

“…An enzyme-bacterial inoculant acts in two forms in silage: whereas bacterial inoculants improve fermentation proile and increase lactic acid bacteria population, enzyme inoculants act on the cell wall and the available higher quantity of soluble compounds, with improvement in silage digestibility [44].…”

The intake of DM DMI is determinant for ingress of nutrients to cater to the requirements for animal maintenance and production, principally the intake of protein and energy. The end-products of fermentation can afect the intake of silages and inluence animal performance, since some organic acids negatively inluence the intake of silage and digestibility of nutrients. For example, acetic and butyric acid have large efects on the intake of silage. Ammonia also can negatively afect the intake of silages. The digestibility can be inluenced by end-products of fermentation and change the characteristics of ensiled plants. The objective of this chapter is to explain how silage end-products of fermentation and changes in the structure of forage resulting from the ensiling process can afect the intake and digestibility of silages. Some control mechanisms of silage fermentation can be used to improve the intake and digestibility of silage. Biological or chemical additives may contribute to the increased intake of silage and improve digestibility. Appropriate management techniques can inluence the result.Keywords: acetic acid, ammonia, animal nutrition, butyric acid, forage ensiling . IntroductionEnsilage is the method of forage conservation based on conversion of water-soluble carbohydrates in organic acids by the activity of lactic acid bacteria, which reduces the pH and preserve the fresh forage [1].The ensiling process show advantages such as conservation of large quantities of forage in short time and forage conservation is less weather dependent. However, a disadvantage of the ensiling process is the relative reduction of feeding value of the silage when compared to the © 2016 The Author(s). Licensee InTech.

Although, correct management of silages and use of additives may stimulate the intake of silages and improve the digestibility of silages.The forages may have changes in the nutritive value due to the procedures during production, conservation and post-opening management and biochemical and microbiology phenomena [3]. Besides the conversion of carbohydrates in organic acids occurs by the partial breakdown of proteins, which gives the non-protein structures. These changes depend on the interaction between microorganisms on the material to be ensiled and amount and type of the substrate [4].The silage quality afects the intake and digestibility of ruminants. Basically, the main factors that can interfere with the fermentation of the silage is th...

“…In support with our results, Ribeiro et al (2002) observed increases in KPH of crossbred bulls as concentrate level increased and a trend for increased backfat thickness as concentrate levels increased. Fugita et al (2012) in Nellore-Angus crossbred cattle fed 50% concentrate diet and Rodrigues et al (2013) in bullocks fed 75% concentrate diet compared to diet B. Concentrate fed heifers or steers had higher (P<0.01) fat thickness and KPH% than forage-fed heifers or steers as reported by Garmyn et al (2010) and Duckett et al (2013).…”

| Twelve Brahman crossbred growing bulls, divided into three groups, were fed three diets; 100% concentrate diet (A), a 1:1 mixed diet on dry matter of Urea-Molasses-Straw (UMS) and concentrate diet (B) and sole UMS diet (C), respectively, to evaluate the effects of concentrate level on slaughterhouse by-products, carcass characteristics and meat traits. The animals were fed for a period of 90 days and three animals from each group were slaughtered at the end of the trial. The results indicated that yield of edible and inedible by-products had no significant difference among diet groups. When expressed in percentage of live weight, hides, shanks, liver and empty stomach were greater (P<0.05) in animals fed diet C compared to those in diet A and B, whereas no difference was found for those between the last two diets. There was no variation between diet A and B in carcass weight, while it was significantly (P<0.01) lower in diet C. Among carcass traits, hotdressing percentage, kidney-pelvic-heart fat, abdominal fat and back fat thickness increased linearly (P<0.01) with the increased level of concentrate in diets, while Longissimus muscle area did not vary among diet groups. Dietary treatments had no influence (P>0.05) on the content of moisture and protein in meat, but concentrate supplementation reduced ash content and increased the amount of fat (P<0.01) compared to UMS group. Therefore, considering carcass and meat traits, a mixed diet of concentrate and UMS may be fed to Brahman crossbred bulls for fattening.* The ME value of each ingredient was estimated using the equation; ME (MJ/kg DM) = 13.50 + 0.263 EE% -0.133 ash % -0.136 ADF% (MAFF, 1984); The ME value of concentrate mixture (100%) was calculated using the estimated ME value of all ingredients; ME value of UMS (100%) was calculated assuming 6.2 MJ ME /kg DM of straw (Khan, 2008) and 13.0 MJ ME /kg DM of molasses (Dugmore, 1995); ME for diet B= Average of diet A and C= 9.65 MJ ME /kg DM of diet
