The effects on performance, digestibility, N utilization and plasma amino acid concentrations of dietary chickpea (Cicer arietinum, var. Kabuli) seed meal, globulin proteins or buffer-insoluble residue (starch / non-starch polysaccharides (NSP)/ lignin) were studied in growing rats. Chickpea meal, defatted soybean meal, chickpea globulins and lactalbumin were each incorporated into diets as the sole source of dietary protein (100 g/kg).

A feeding trial was conducted in order to evaluate the influence of live yeast cells ( saccharomyces cerevisiae ) on milk production and composition, and on blood parameters in late lactation. The experiment was performed on forty Croatian crossbred dairy sheep divided into a control group without live yeast cells (CD = control diet) and the experimental group with live

This study elucidated the effects of replacing soybean meal with silkworm meal on production performance, apparent total tract digestibility of nutrients, blood profile, and egg quality traits in white leghorn layers. A total of 150 white leghorn laying birds (52 weeks of age) were randomly divided into fifteen replicate groups (n=10 per replicate), and reared on five experimental diets having three replicates allocated to each treatment group for a period of six weeks. Five iso-nitrogenous and iso-caloric diets (D) were utilized as; 0 (D1), 25 (D2), 50 (D3), 75 (D4) and 100% (D5) as replacement of soybean meal with silkworm meal in commercial layer rations. The weight of the bird, daily feed intake (g/day/bird), hen day production (%), average egg weight
(g), and feed conversion ratio did not differ significantly (P>0.05) among the dietary groups. Apparent total tract digestibility of nutrients was not different in the control group compared to treatment groups. Blood profile and egg quality parameters also showed no significant (P>0.05) differences among dietary groups. The egg weight, albumen height, yolk weight and shell thickness were not affected (P>0.05) by dietary treatments. Based on our results, it could be concluded that silkworm meal can be effectively used as an alternative protein sourceto soybean meal without any adverse effects on the layers.

The study aimed to investigate the effect of replacing soybean meal (SBM) by treated, either by heat (HJM) or by boiling (BJM), Jojoba meal (JM), to eliminate the negative effects of antinutritional factors, at 10, 20 and 30% replacing levels in diets of sea bream (Sparus aurata)) fingerlings on growth performance, nutrient utilization, body biochemical composition, middle intestine morphology and measuring of some hematological parameters of sea bream. Results indicated an enhancement in growth and feed utilization for all fish groups fed boiled followed by heated jojoba meal at 20% inclusion level compared to the control and other tested fish groups. Results of fish biochemical analyses indicate significant increase in crude protein contents in fish fed 10 and 20% HJM and 20% BJM. The present results also showed obvious increment in lipid contents as the level of JM inclusion level increase. Serum total protein, albumin and globulin levels indicated no negative effects when soybean meal was partially replaced by jojoba meal. Also, results indicate pronounced gradual decrease in serum cholesterol levels coincided with an increase in triglyceride. Middle intestine morphology examination showed significant variations in thickness of muscularis layer, villi length and width and also number of goblet cells.

Introduction of formulated diet particles for larval culture will simplify hatchery protocols and promote consistent survival, while decreasing total operating costs. The blue swimmer crab, Portunus pelagicus, is a commercially important species with substantial aquaculture potentials in the Indo-Pacific region. Feeding trials aimed at investigating protein nutrition of P. pelagicus larvae were undertaken with the megalopae instar. Microbound diets (MBD) with four different dietary protein sources (fish meal, squid meal, krill meal and soybean meal) were formulated and fed to newly molted megalopae until they metamorphosed to the first crab stage. Thirty megalopae were reared individually for each dietary treatment, with the addition of two control treatments of megalopae fed live Artemia nauplii and an unfed treatment.Survival was high for all fed treatments (73.3–93.3%), while total mortality was recorded for the unfed control. Megalopae fed the fish meal based MBD demonstrated higher survival than that of megalopea fed live Artemia, suggesting that MBD have the potential to completely replace live food for the culture of P. pelagicus megalopae without adversely affecting their survival. These results also suggest that P. pelagicus megalopae are able to adapt to a range of dietary protein sources. For megalopae fed live Artemia nauplii, mean development time was significantly shorter (4.0 ± 0.4 days) and the mean carapace width and dry weight of newly settled first stage crabs were significantly greater, (3.1 ± 0.0 mm, 1.3 ± 0.1 mg, respectively) than megalopae in all other fed treatments. Among MBD treatments, no significant difference in mean development time was detected, however, the mean carapace width of crabs that metamorphosed from megalopae fed fish meal based MBD (2.8 ± 0.0 mm) was larger than those fed squid meal based MBD (2.6 ±0.0 mm) and the mean dry weight of individuals fed fish meal based MBD (0.87 ± 0.04 mg) was also significantly heavier than those fed soybean meal based MBD (0.72 ± 0.04 mg). The outcome of this research provides valuable information regarding protein requirements of P. pelagicus megalopae and will aid in optimising formulated diet particles for potential use in commercial hatcheries.

A study was conducted to estimate dry matter (DM) degradability in the rumen of lambs offered a basal soybean meal and sorghum grain diet with three levels of white mulberry (WM) leaves (Morus alba). Diets consisted of 90% concentrate and 10% sorghum straw, which was incrementally replaced by WM leaves at 0% (control diet, T1), 2.5% (T2), and 5% (T3) of the total ration. Crude protein (CP) in WM was 21.8% (DM basis). Diets had equal CP (14% DM basis) and metabolizable energy (10.8 MJ/kg DM) content. Three non-castrated Pelibuey male lambs fitted with permanent rumen cannula were utilized in a 3 × 3 Latin square design. Each experimental period consisted of 10 days of adaptation followed by sampling. DM degradability was determined using the nylon bag technique. Bags contained the experimental diets offered in each period and were incubated in rumen in pairs for 4, 8, 12, 24, and 48 h. The potential degradation was higher (P

An eight-week experiment was carried out to evaluate the effects of different protein sources (fish and haemoglobin meal, soybean meal and torula yeast), in practical diets, on growth, body composition and gut morphology of fingerling grey mullet (Mugil cephalus). Weight gain (%), SGR, FCR, N retention, PER, PGR, FDR and carcass composition of fish were not significantly affected by the

Realizou-se este trabalho no setor de avicultura de DZO-UFLA, durante o período de junho a outubro de 2003. Foram utilizados 112 galos reprodutores da linhagem Lohmann- LSL, de 16 até 32 semanas de idade. As aves foram distribuídas num delineamento em blocos ao acaso, em arranjo fatorial 3x2 + 1, com três tipos de óleo (Soja, Canola e Girassol), e dois níveis de vitamina E (200 e 400 mg/kg de ração) e o controle (sem óleo e 0 mg de suplementação de vitamina E). As rações experimentais foram elaboradas à base de milho e farelo de soja. Nas 28ª e 29ª semanas foram realizadas coletas de sêmen para avaliação da motilidade, volume do sêmen, concentração, número de células totais e a morfologia espermática. As análises foram realizadas com utilização do programa SAEG. Foi observada interação significativa (P=0,08) entre as fontes de óleos testadas e os níveis de vitamina E, para a motilidade espermática na 28ª semana de idade. Não foi observada diferença significativa (P>0,05) entre as fontes de óleo nem entre os níveis de vitamina E para nenhuma das variáveis estudadas. Conclui-se que qualquer fonte de óleo das utilizadas neste estudo pode ser adicionada à ração de galos reprodutores sem necessidade de elevados níveis de vitamina E.
