IcaCuba Occ-10, alone or mixed with forage of Cenchrus purpureus cv.

All treatments showed similar dry matter content (P>0.05), lower than the recommended values (30-35 %). The inclusion of vinasse reduced the pH compared to the treatment without it (P<0.01). similarly, the dry matter:pH ratio improved when vinasse was included as an additive. The treatments of Tithonia alone showed a dark green color, the mixture of Tithonia and Cenchrus forages resulted in olive green with dark tones that disappeared when vinasse was added. It was the latter that had a coloration most in line with an excellent quality silage. In the silages with vinasse, a pleasant smell was obtained, similar to that suggested for silages of very good characteristics. The silages obtained from T. diversifolia, alone or mixed with C. purpureus cv. CT-608 forage, showed sufficient quality indicators to recommend their evaluation on a larger scale, even starting from materials with low dry matter contents. The organoleptic and chemical evaluation supports its stability and acceptability. The inclusion of vinasse in the preservation process of these silages is confirmed as an economical and effective strategy for the conservation of tropical forages, even forages with high protein content and high buffering capacity such as tithonia. Its use as an additive reduces the acid detergent fiber content, pH, and improves dry matter yield, the dry matter:pH ratio, and its organoleptic characteristics, such as color and odor.}, }

Two treatments were established: 1) grazing on improved and natural grasses and 2) grazing in a silvopastoral system of T. diversifolia grasses, associated in 100 % of the area. The animals grazed for 24 hours on 10 hectares (ha) of improved grasses, divided into two systems of 5 ha each. The crude protein in the control treatment was 9.54 %, while in the SPS it was 10.5 % in the grass and 22.7 % in Tithonia. In the rumen of animals that grazed in the SPS with Tithonia, the total number of viable bacteria was higher (p<0.0001), while the proteolytic bacteria were 47.17 x 105 CFU/mL and those of the control treatment, 19.42 x 105 CFU/mL, which represents 2.43 times fewer bacteria. There were no effects on the number of cellulolytic fungi. The silvopastoral system increased the number of cellulolytic bacteria and the protozoa were reduced 3.5 times. Methane production was 37.0472 g/kg of digested OM with grasses and in the SPS with Tithonia 34.788 g/kg of digested OM. It is concluded that the rumen microbial community of Holstein x Zebu non- castrated cattle that grazed in SPS with Tithonia showed a higher number of total viable bacteria, proteolytic bacteria, cellulolytic bacteria, a lower number of protozoa and less CH4 compared to the control that grazed in grass areas.}, }

A total of 180 animals with an average initial weight of 10.34 (0.08) g were randomly placed in twelve circular cement tanks with a capacity of 68 L. The experimental treatments consisted of four diets: the commercial catfish pre-fattening feed (control) and the remaining ones with 6, 9 and 12 % cassava leaf meal as a partial substitute for soybean and wheat. The experimental cassava leaf meal had 23.87 % crude protein and 16.60 % crude fiber. There were not differences between the amount of food (87.13, 85.57, 86.43 and 85.33 g) and protein supplied per animal (26.80, 26.57, 26.21 and 25.78 g). The growth rates (62.58, 61.31, 62.44 and 59.95 g of final average weight) and the feed conversion ratio (1.65, 1.68, 1.66 and 1.71) were not affected by either diet. Survival was 100 % for all treatments. Economic analysis showed that increasing the amount of cassava leaf meal reduced feeding and rations costs in all treatments. The greatest cost savings resulted from the inclusion of 9 % cassava leaf meal. It is concluded that the inclusion of up to 12 % cassava leaf meal does not compromise the productive performance of Clarias gariepinus small fish and has a positive economic impact.}, }

The samples under study come from 62 accessions of C. purpureus from the Germplasm Bank of Grasses and Forages of Instituto de Ciencia Animal. The type of reproduction of the accessions was determined by Polymerase Chain Reaction (PCR) with the combination of direct and reverse primers p779/p780 completely linked to the aposporic apomixis. It was not obtained DNA amplification from the C. purpureus accessions and the Urochloa spp. controls that were negative for aposporic apomixis. However, DNA amplification was obtained from positive controls to aposporic apomixis in Urochloa spp. accessions reported as apomictic. The amplification products revealed a well-defined polymorphic band on the gels with an approximate size of 950 base pairs. The p779/p780 primers amplified the apomixis-positive Urochloa accessions, but did not amplify the negative controls or the C. purpureus accessions. These results suggest that (I) or the 62 accessions of C. purpureus from ICA reproduce sexually and do not exhibit aposporic apomixis, or that (II) the primers are not specific to this species.}, }

The data were analyzed using the Statistic v7.1 software under a completely randomized design and comparison of Tukey's means. The heaviest final body weight and highest feed consumption were observed in the ACOM group, followed by MO. The heaviest carcass and the lightest viscera corresponded to ACOM; But, the weight of the meat was similar in all treatments. Protein content, ether extract, ash, and pH were not modified by the diets containing foliage meal. Up to 50 % of foliage meal can be included in quail diets, reducing the consumption of concentrate feed, maintaining meat quality and increasing carcass yield.}, }

The average weight gain (AWG) significantly increased in broilers fed diets MSG, MSG-LCLRM, and MSG-HCLRM, with the highest AWG (p<0.05) recorded among broilers fed diet MSG-HCLRM. The relative growth rate was not significantly influenced across all treatment groups (p>0.05). Broilers fed MSG had significantly lower vitality rates (VR) compared to other groups, while those on diet MSG-HCLRM exhibited the most significant VR (p<0.05). Most hematological and serum biochemical indices were negatively impacted in broilers on MSG (p<0.05). Serum antioxidant enzymes were significantly depressed in broilers on MSG (p<0.05). Serum potassium and sodium concentrations were unaffected by MSG (p>0.05), but serum chloride concentration increased significantly (p<0.05).
