“…On the other hand, soybean fodder meadows can also be grazed or harvested from the flowering phase almost until maturity for its use as high quality hay (Kökten et al, 2014). Reséndiz et al (2013) evaluated a whole food diet for sheep with 30% alfalfa, and found a greater DMI (36%), this difference is attributed to the fact that the lambs used had higher LW (22.1 vs 15.51 kg) when compared to the lambs used in the present study. On the other hand, Protes et al (2018) did not find differences in DMI in lambs fed with silage made from soybean and sorghum fodder.…”

Objective: To evaluate the productive behavior of Creole sheep in the tropics fed a whole food diet that includes soybean (FS, Glycine max) fodder at different phenological stages. Methodology: The treatments T1: control, T2: 30% (SF-56 d), T3: 30% (SF-68 d), T4: 30% (SF-85 d), T5: 30% (SF-110 d) were assigned randomly to 30 male Creole sheep (15.51±1.6 kg LW). The experiment lasted 56 d. The variables evaluated were: dry matter consumption (DMC), daily weight gain (DWG) and feed conversion (FC). The experimental design wascompletely randomized and the averages of the treatments were compared using the Tukey test. Results: Differences (p<0.05) were found in DMC, DWG and FC. The DMC was lower (p<0.05) in the control group. The DWG was higher in the animals that consumed soybean fodder compared to the control group (0.205 vs 0.121 kg d-1). The FC decreased (p<0.05) 51% in T3 (SF 68 d), with respect to the control group. Study Limitations: The nutrient contribution of soybean fodder is based on the phenological stage of the plant. Likewise, producers in the tropical region have scarce knowledge about how to incorporate it in the feeding of small ruminants. Conclusions: The inclusion of 30% of soybean fodder at 68 d of age in a whole food diet improves the productive performance of the lambs because it increases daily weight gain and decreases feed conversion.

“…The degradability over time of the different diets evaluated are in accordance with the results shown above and are in agreement with the reports of several researchers. Resendiz et al (29) evaluated different levels of alfalfa (Medicago sativa L.) in the diet of lambs. They observed that by increasing the levels of alfalfa decreased DM degradability, explaining the decrease in dietary fiber increase and the lignin content contributed by the alfalfa since it next to the cellulose form a barrier protecting DM from microorganisms attack.…”

Senna spectabilis FRUIT ON HAIR LAMBS FEEDING: DIGESTIBILITY, BLOOD METABOLITES, AND RUMINAL KINETIC

In recent years sheep, farming has emerged as an alternative production system especially in dry areas. The use of leaves and fruit from some trees has become an alternative for feeding for ruminants; however, studies on these species are scarce. The objective of this study was to evaluate the effect of S. spectabilis fruit meal on in vivo and in vitro digestibility, blood metabolites, and ruminal kinetics in hair lambs. This study was carried out at Las Brisas farm, University of Tolima - Colombia. Twelve male hair lambs with body weight of 20.3 ± 2.5 kg were used. Animals were distributed in an experimental 4x4 Latin square design. The treatments consisted of diets based on Dichanthium spp hay with different inclusion levels of S. spectabilis fruit meal (15, 30, and 45%). A linear increasing effect (P <0.05) was observed for in vivo and in vitro digestibility of dry matter, organic matter, and crude protein; likewise, plasma urea and ruminal degradability increased as the level of supplementation of S. spectabilis increased. The meal of S. spectabilis improves digestibility, protein intake, and ruminal kinetics in hair lambs; therefore, it is suggested as a promising alternative for ruminants feeding in dry tropic regions.

“…La ganancia diaria de peso se estimó mediante una regresión lineal por animal con peso vivo el día del pesaje como variable independiente (y) sobre el día del experimento como variable dependiente (x), utilizando los coeficientes de regresión significativos (P<0.05) como estimadores no sesgados de la ganancia de peso en kg/ovino/día (Arriaga-Jordán y Holmes, 1986); método que minimiza las fluctuaciones de peso vivo por cambios en el contenido gastrointestinal. La conversión alimenticia se calculó dividiendo el consumo de materia seca entre la ganancia diaria de peso, y la eficiencia alimenticia, dividiendo la ganancia diaria de peso entre el consumo diario de materia seca (Resendiz et al, 2013).…”

Background: Sheep production in central Mexico is an important livestock activity that requires the evaluation of feeding strategies to increase or sustain production in times of feed scarcity. Objective: To evaluate the performance of ewes fed diets with different levels of inclusion of Typha latifolia. Methodology: Fifteen criollo adult ewes were randomly grouped to receive different levels of tule (Typha latifolia) in their feeding as a complement to grazing. An incomplete randomized block design was employed. Daily live weight gain, intake, and body condition score were evaluated, as well as grassland parameters and the chemical composition of feeds. The experiment lasted 60 days divided in four measurement periods. All ewes were supplemented with a commercial pelleted concentrate. The control group (T1) had 0g DM of tule, 461.75 g DM commercial concentrate, and 8 h grazing; T2 had 116.5g DM of tule, 461.75 g DM commercial concentrate, and 8 h grazing; and T3 had 174.75 g DM of tule, 461.75 g DM commercial concentrate, and 8 h grazing. Results: There were significant differences (P<0.05) in DM intake of pasture and Typha latifolia. There were no significant differences among treatments (P>0.05) for initial and final live weight, daily weight gain and body condition score. Implications: Typha latifolia is an available non-conventional forage source for adult sheep maintenance in the dry season for small-scale systems. Conclusion: The inclusion of Typha latifolia in diets for sheep may be a good option for feeding adult ewes in maintenance.
