The aim of our study was to evaluate the nutritional value of the breast and thigh muscle of chukar partridge (Alectoris chukar) under intensive fattening conditions. Commercial feeding mixtures for broilers were used. Live weight of 60 partridges (birds were not sexed) was controlled during 90 days of fattening. After the fattening was finished, 30 birds were selected to monitor the carcass yield. Breast and thigh muscle were used for chemical analysis of crude protein (Kjeldahl method), total lipids (fat analyser ANKOMXT10), ash (Muffle furnace - 550° C) and gross energy (calorimetry). Average values ​​of live weight were increasing in the course of fattening; at the end of fattening the live weight reached 0.452 kg. The carcass yield, breast muscle yield and thigh yield were evaluated (73.72%, 18.09%, 20.80%, respectively). Chemical analysis showed a highly significant difference (P ≤ 0.01) between the breast and thigh muscle for crude protein, fat, ash and gross energy. The ash content demonstrated a significant difference (P ≤ 0.05) between the breast and thigh muscle. This study brings new data on the nutritional value of the meat of chukar partridge that can be used for reccomendation of a suitable feeding mixture.

An understanding of feed ingredient digestibility for the pirarucu is a fundamental step in the development of feeds that promote proper growth of the specie while in captivity. A digestibility trial was conducted with four treatments in triplicate (corn starch, corn, rice bran and wheat bran) to evaluate the digestibility of dry matter, gross energy, crude protein and amino acids by the pirarucu. We used indirect methodology with the inclusion of chromium oxide at 0.1% in the feeds. In total, 18 juveniles were used, with an average live weight of 235 ± 36 g. The sampled juveniles were trained to consume the feeds prior to testing. The corn and cornstarch presented the best apparent digestibility coefficients (ADCs) of dry matter, with 76.37% and 70.66%, respectively, followed by rice bran (46.23%) and wheat bran (45.13%). The best ADCs of crude protein were observed in corn (93.44%) and cornstarch (90.94%) compared to rice bran (68.23%) and wheat bran (68.58%). There was no significant difference in the ADC of gross energy; the values ranged from 47.10% for corn starch to 40.10% for corn. The corn and corn starch presented the best ADCs for all the amino acids evaluated, followed by rice bran and wheat bran.

Thirty six New Zealand fryer rabbit (bucks) averaging 874g in body weight were fed on three diets blended with 0, 7, 14% kolaunt pod meal (KPM) and10, 20, and 30% Brewers spent grains (BSG). Other dietary components included maize, soyabean meal, bone meal, salt and vitamin-mineral mixture. The trail lasted for 98 day. Significantly differences (P < 0.05) were found among the three rations with respect to daily live weight gains, feed intake and water intake. There were significant difference among the rations with respect to percent carcass yield, feet, blood and unemptied alimentary canal. However there were no significant (P > 0.05) differences among the three rations with respect to head, tail, and liver weight expressed as percentage of live weight. There was no significant treatment effect no the wholesale cuts. The chemical composition of the meat of rabbits fed 14% KPM + 3-% BSG diet was significantly lower in energy value, % moisture and % fat. The results showed that a diet fortified with 30% BSG and 14% KPM will support good growth as well as improved carcass yield of rabbits.

The objective of this work was to determine the nutritional value of different protein sources for "dourado" (Salminus brasiliensis). Thirty juveniles per group (33.51±1.4 g) were hand fed on a reference diet (70%) added of tested ingredients (30%) and chromium oxide III (0.1%). Apparent digestibility coefficients of the gross energy (ADC GE), crude protein (ADC CP) and amino acids of the tested ingredients were evaluated. Corn gluten meal yielded the best results for ADC GE and ADC CP (95.7 and 96.9%, respectively) amongst plant ingredients. Spray-dried blood meal yielded the best values of ADC GE and ADC CP amongst animal ingredients (94.1 and 96.3%, respectively). Wheat bran yielded poorest ADCs coefficients (77 for ADC GE and 88.2% for ADC CP).

Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC) of dry matter (ADCDM), crude protein (ADCCP), gross energy (ADCGE) and amino acids (ADCAA) of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g). The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT), using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg-1 crude protein and 3,692 Kcal kg-1 gross energy. Additionally 1.0 g kg-1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%), followed by the other ingredients. There was no significant difference between the soybean meal (95.16%), fish meal (92.97%) and the corn meal (91.90%) for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%). The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients.

Significant Difference

It was confirmed in metabolic experiments with 4 individuals of roe deer (2 males and 2 females with the live weight of 20.8 and 17.9 kg, respectively) that due to the animals&rsquo; selective choice of a part of feeds there was no significant difference in the intake of lucerne hay of different quality and high-quality meadow hay (515.86 &plusmn; 66.97 and 597.82 &plusmn; 94.87 g, respectively). However, different quality of lucerne hay influenced the animals&rsquo; intake of crude protein and crude fibre. When the animals were fed meadow hay, they took in significantly less crude protein and fibre and significantly more nitrogen-free extract, fat and ash. Digestibility of crude protein was observed to be significantly decreased in hay of lower quality (by 10.1%). Digestibility coefficients for crude protein, crude fibre, organic matter and fat were significantly lower in grass hay compared to lucerne hay. Based on the coefficients of nutrient digestibility it can be stated that meadow hay, even if of excellent quality, is not a suitable supplement for the roe deer. &nbsp;

AbstractEuropean (no. = 36) and hybrid (¼ Mesopotamian, ¾ European; no. = 36) fallow deer (Dama dama) were evaluated for weight gain and energy intake from 10 to 21 months of age. Twelve each of bucks, does and castrated males (haviers) were tested for each genotype, in both concentrate-fed and pasture-based feeding systems. Based on weekly weighing hybrids (H) in each of the sex classes grew more rapidly (5 g/day across all groups) than the European (E) fallow deer (P < 0·05). Haviers given concentrates grew significantly faster than pasture-fed haviers (P < 0·01), whilst does grown on pasture grew significantly faster than those given concentrates (P < 0·01). There was no significant difference in pattern of growth between bucks on pasture and those given concentrates (P > 0·05). Does grew significantly less (P < 0·01) than bucks and haviers in spring, summer and winter but environmental differences between years could not be accounted for in the analysis.Animals of all sexes and genotypes experienced rapid growth from 10 to 12 months of age (spring) and this was associated with energy intakes according to metabolic body weight (M0·75) these ranging between 0·8 and 1·1 MJ metabolizable energy (ME) per kg M0·75 per day. There were significantly (P < 0·01) higher levels of energy consumed by H does and haviers in the summer, compared with their E counterparts but this was not associated with greater growth rates. However, H does had significantly higher (P < 0·01) dressing proportions at slaughter than E does. The energy intake on a metabolic body weight basis for most groups declined to between 0·7 and 0·8 MJ ME per kg M0·75 per day from 12 to 21 months of age, except for the does, which declined even further to between 0·5 and 0·6 MJ ME per kg M0·75 per day from 17 months of age.There were no significant differences between E and H deer for energy intakes per M0·75, and H deer were slightly more energy efficient than their E counterparts in terms of growth rate in relation to annual gross energy intake. The food intake : weight gain ratio increased considerably for both genotypes after 14 months of age, indicating the desirability for slaughtering as soon as animals reach the target live weight. It was concluded that the crossbreeding system described is production efficient and produced offspring that reached slaughter weight sooner than E fallow deer and thereby produced carcasses with a greater wholesale value than their E counterparts of the same age.

The objective of this study was to evaluate the effect of crude protein substitution of soybean meal with urea (slow-release or otherwise) on the carcass and the meat characteristics of finished steers in confinement. Twenty-seven castrated, purebred and Charolais-Nelore crossbred steers with a mean age of 20 ± 1,5 months and initial mean live weight of 293 ± 31 kg, were distributed in three treatments: Protected Urea (concentrate containing slow degradation urea ); Soybean meal (concentrate containing soybean meal) and Urea Common (concentrate containing common urea). A randomized block experimental design (racial predominance) was used, with three treatments and nine replications, with the animal as the experimental unit. Feeding treatments did not influence the hot and cold carcass weight and yield. The fat thickness that covered the carcass was not altered, according to the diets studied, being on average 3.97 ± 0.94 mm. The measurements and the carcass compactness were not altered by the diets, presenting average values of 127.55; 74.86; 39.86; 38.84 and 25.72 cm for carcass length, leg and arm, arm perimeter and cushion thickness, respectively. A significant difference was observed in marbling, and the meat of the animals treated with soybean meal were higher than those treated with protected urea (3.72 vs 2.28 points).

Amaranth leaves are edible vegetables with high nutritional value that depends on the harvest stage. This study evaluated the nutritional and chemical profile of amaranth leaves harvested at days 65 and 120. Samples were collected, air-dried, and milled to pass through a 1-mm sieve before analysis. Higher (p < 0.05) crude protein (CP) and gross energy (GE) were observed in early harvested leaves than late harvested leaves. In addition, late harvested leaves had higher (p < 0.05) calcium, magnesium, and sodium contents than early harvested leaves; early harvested leaves had higher (p < 0.05) threonine, lysine, and leucine contents than late harvested leaves. Furthermore, early harvested leaves showed higher (p < 0.05) rutin, hyperoside, tryptophan, quercetin, and kaempferol rutinoside contents than late harvested leaves. A strong positive correlation was observed between nutrition composition and phenolic compounds. It can be concluded that both early and late harvested amaranth leaves are a promising source of nutrients and phenolic compounds that can help in providing new opportunities for their use in the food and pharmaceutical industries.

1. Twenty feeding and digestibility trials were carried out on seven tropical grasses to determine their nutritional value at different stages of growth, and to study their suitability as possible pasture grasses.2. Content of crude protein was relatively high at immature growth stages of the forages, and declined rapidly with the onset of flowering.3. Digestibility of dry matter and gross energy increased in most of the forages tested to the 5-week stage of regrowth but declined rapidly in mature stages of forages tested at 6 or 8 weeks of regrowth. Digestibility of crude protein declined with increasing maturity of the forages.4. The Nutritive Value Index of each forage was highest at four or five weeks of regrowth. The optimum time to graze the forages tested would occur between 4 and 5 weeks of regrowth, at the stage when flowering commences. This would combine high yield of forage with high nutritional value.
