“…In this experiment, mature sugarcane was used, whereas in earlier studies, premature sugarcane was fed. The CP contents of concentrate (wheat roti) fed to elephants was lower than earlier reports (Herrera-Saldana et al 1990). This difference in CP content of wheat might be due to agronomic conditions (Brandt et al 2000).…”

Two feeding trials were conducted to evaluate the feed consumption, nutrient utilisation, blood biochemical and faecal microbial profile of working and nonworking semicaptive Asian elephant. During each trial, six captive elephants were placed in two groups of three each. Elephants in one group performed the scheduled work at the park, i.e., 4-h safari with tourists, while the other group performed no work. During nighttime, all the elephants were kept in respective individual enclosure so that feed consumption and faeces voided could be measured accurately. During day time, all the elephants were allowed to forage in nearby forest. Intake (kg/d) of sugarcane (Saccharum officinarum) and sugarcane leaves was more (P < 0.01) in nonworking elephants as compared to working elephants. Working elephants consumed more (P < 0.01) forages during foraging than nonworking elephants. Average daily dry matter intake (DMI) and DMI (% body weight, BW) were comparable between the groups. Apparent digestibility (%) of DM, OM, crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose, cellulose and gross energy (GE) were higher (P < 0.01) in working than nonworking elephants. Activity of ALT (IU/l) was higher in working as compared to nonworking elephants. The relative population of Fibrobacter succinogenes and Ruminococcus flavefaciens and total fungi were numerically increased in working elephants as compared to nonworking elephants. It was concluded that 4 h of work has no adverse impact on food consumption and blood metabolite profile of semicaptive Asian elephants; rather it improved the digestibility of nutrients. Work showed positive effect in restricting the calorie supply closer to requirement.

“…Excessive fermentation of starch to VFA in the rumen may, therefore, lower the dry matter intake (DMI) of high producing dairy cows (McCarthy et al, 1989;Overton et al, 1995). Other studies (Herrera-Saldana et al, 1990;Strzetelski et al, 2008), however, have shown no change in intake as degradation of starch in the rumen increased. The type of grain species of differentiated ruminal starch degradation used in our trial did not have any negative impact on feed DM intake, too.…”

“…Herrera-Saldana et al (1990) reported that the effective rumen degradability of maize, barley, and wheat amounted to 62, 90, and 95, respectively. Grain species rich in starch easily degradable in the rumen increase the level of propionic acid (the only glucogenic VFA (volatile fatty acids)) in ruminal fluid (Overton et al, 1995).…”

A two-factorial experiment was carried out on 6 groups (10 animals each) of Polish Black and White Holstein-Friesian cows in the transition period to determine the effect of glucogenic additive (GA) to the diets containing grains of varied ruminal starch degradation on cow performance. The animals from 3 control groups (C-groups) were fed the diets without any additive, whereas 3 other, experimental ones (A-groups) received the diets with additive of glucogenic preparation (450 g per head/day) comprising calcium propionate and loose propylene glycol (1 : 1). In the control groups as well as in the experimental ones, three analogical treatments, differing in concentrate composed of grain species of varying ruminal degradability of starch, i.e. maize (M) -low ruminal degradability, barley and wheat (BW) -high ruminal degradability and marriage of them (MBW) were conducted. Finally, the treatments were: C-M, C-BW, C-MBW, A-M, A-BW, and A-MBW. The rations of all groups based on maize silage, haylage, and meadow hay were mixed at 69 : 19 : 12 ratio (dry matter (DM) basis) and given ad libitum. Besides, all the animals received adequate concentrate rations to satisfy their nutritional requirements. The experiment started two weeks before the expected parturition and lasted till the 6 th lactation week. Neither GA nor a type of grain in the diets showed significant negative influence on DM intake. A glucogenic additive has positively affected some basal nutrient digestibility, elevating significantly DM and crude protein (CP) coefficients of the apparent total tract digestibility (CATTD), by about 3 percentage points. The GA × grain interactions (P ≤ 0.05) in CATTD of CP and nitrogen-free extract (NFE) were stated, with the peak values reported in the A-BW treatment. GA increased (P ≤ 0.05) daily milk yield by nearly 5% in comparison with the control treatments. GA × grain interaction was noted with the best effect in the treatment where GA was given along with maize-barley-wheat-based concentrate. Besides, the glucogenic additive decreased (P ≤ 0.05) protein (PDI) expenditure per 1 kg of fat-corrected milk (FCM) by ca. 6% and raised (by 0.15 percentage point in week 6) protein content, while lowered the urea milk level in weeks 3 and 6 of lactation by approximately 15%. It showed beneficial effect on cow reproductive indicators reducing the time interval from calving to successful insemination and improving insemination index.

“…Segundo HERRERA-SALDANA et al (1990), o amido de milho é relativamente resistente à degradação no rúmen. ORSKOV et al (1969) relataram que quantidades consideráveis de amido da dieta podem escapar da digestão no rúmen, quando são fornecidas aos animais dietas ricas em milho quebrado ou moído.…”

RESUMO -O objetivo deste trabalho foi avaliar o efeito da substituição do milho por bagaço de mandioca, no concentrado das rações, sobre o consumo de matéria seca (MS), matéria orgânica (MO) e proteína bruta (PB) de bovinos em crescimento. Dezesseis bezerros mestiços machos inteiros foram distribuídos em delineamento em blocos casualizados completos, em dois períodos. Quatro tipos de concentrado foram testados em associação com o fornecimento à vontade de feno de aveia/azevém (Avena strigosa, L.; Lolium multiflorum, L.) e suplementação média de concentrado de 0,83% PV. Os concentrados fornecidos aos animais diferenciaram-se pelo nível de substituição do milho por bagaço de mandioca: T1 = 0,0, T2 = 33,0, T3 = 66,0 e T4 = 99,0% ABSTRACT -The objective of this study was to evaluate the effect of the substitution of corn by cassava bagasse in the concentrate on dry matter, organic matter and crude protein intake in growing cattle. Sixteen crossbred bulls were allotted to a completely randomized block design, in two periods. Four types of concentrate were tested in association with an ad libitum allowance of oat/ryegrass hay (Avena strigosa, L.; Lolium multiflorum, L.)and an average concentrate supplementation of .83% LW. The concentrates fed to the animals were different of corn by cassava bagasse by the substitution levels of corn: T1 = 0.0, T2 = 33.0, T3 = 66.0, and T.04 = 99%. There was a quadratic relation on DM, OM and CP intake. The maximum DM, OM and CP intake was, respectively, 88.53, 82.34, and 10.61 g/kg .75 . The corn by cassava bagasse substitution levels which produced the maximum intakes were: 48.74, 44.14, and 43.75%, respectively, for DM, OM, and CP. Higher corn by cassava bagasse substitution levels in the concentrate reduced the intake of the components studied. IntroduçãoBovinos em crescimento apresentam alta exigência de nutrientes que, geralmente, não são encontrados, em níveis adequados, em dietas constituídas só por volumosos. Por isso, é necessária a suplementação com concentrados que, normalmente, têm preço elevado, aumentando o custo de produção. Um dos principais alimentos utilizados na formulação de concentrados é o milho. Porém, apesar de sua boa qualidade, muitas pesquisas são realizadas com o objetivo de estudar alternativas para sua substituição em dietas para bovinos. Os ruminantes que consomem milho concorrem com aves e suínos, que necessitam mais desta fonte de alimento, por não possuírem a mesma capacidade de aproveitamento das fibras que os ruminantes (MELLO et al., 1981). Além de grãos de cereais, vários subprodutos, como farelo de arroz,
