“…Additionally, the digestibility decreases linearly with the inclusion of coffee husks (Souza et al 2006). In sheep, adding 112.5 g of coffee pulp to the diet daily during estrus synchronization and early gestation reduces the pregnancy rate, probably due to the caffeine concentration present in the by-product (Salinas-Rios et al 2016), which is a stimulant of the central nervous system (González and Ramirez-Mares, 2014). In addition to caffeine, coffee pulp contains natural antioxidants (Salinas et al 2014), which have been observed to improve the immune response (Morán et al 2012).…”

ABSTRACT. The objective of this study was to evaluate the productivity and health of fattening lambs fed different levels of coffee pulp in their diets. Thirty-five crossbred lambs with an average weight of 21.8 kg were fed isoproteic and isoenergetic diets with different percentages of coffee pulp (T0: control; T1: 7%; T2: 14%, T3: 21% and T4: 28%), the base diet was formulated with corn, soybean meal, alfalfa stubble, molasses, urea and mineral salt. The fattening period was 98 days. Productivity was measured by weight gain, feed intake and feed conversion. At the beginning and end of the study, blood samples were taken to determine the health status using a biochemical profile and blood count. Analysis of variance was performed using the initial weight as the covariate for the productive variables and the initial values of the analytes in the blood chemistry and hematological analysis tests. The coffee pulp did not affect productivity, although the amount of neutrophils decreased (P<0.05) as the coffee pulp in the diet increased. In all treatments, urea exceeded the reference values, whereas creatinine was below the reference values. We concluded that the inclusion of up to 28% coffee pulp in the diet did not affect the productive parameters, decreases the neutrophil count without affect health status of lambs during fattening.

“…Inclusion of pulp for a short period prior to breeding did not affect the reproductive variables. In a previous study (Salinas-Rios et al, 2016), we found that supplementing with 450 g of concentrate with 25% of coffee pulp (corresponding to a coffee pulp consumption of 112.5 g per day) for 25 days before and 25 days after CIDR withdrawal resulted in decreased gestation percentage, which was attributed to the caffeine present in coffee pulp. If ewes consumed 1.5 kg feed, then pulp consumption was 75 g for the treatment with 5% inclusion, and 150 g for the treatment with 10%.…”

“…If ewes consumed 1.5 kg feed, then pulp consumption was 75 g for the treatment with 5% inclusion, and 150 g for the treatment with 10%. On average, 5% inclusion corresponds to a lower level, and 10% at a higher level than previously offered (Salinas-Rios et al, 2016); therefore, we assume that up to 10% pulp supplementation for a short period is feasible, although the maximum inclusion should be evaluated.…”

“…Several researchers have studied antioxidant supplementation during these stages in order to increase antioxidant capacity (Casamassima et al, 2012). A study by Salinas-Rios et al (2016) found that antioxidant capacity decreases at the beginning of gestation. Thus, demand for antioxidants could increase prior to pregnancy and in early gestation.…”

Background: Coffee pulp has a high content of antioxidants capable of modifying the oxidative status in small ruminants. However, high amounts for a prolonged time can reduce fertility. Objective: To determine the effect of two inclusion levels of coffee pulp during estrous synchronization on reproductive variables and oxidative status of primiparous ewes. Methods: Sixty Suffolk x Dorset primiparous ewes were distributed into three treatments in a completely randomized design; T0: (n=20) 1.5 kg balanced diet, T1: (n=20) 1.5 kg balanced diet and 5% coffee pulp, T2: (n=20) 1.5 kg balanced diet and 10% coffee pulp. Supplementation was given for 16 days before estrus synchronization and until the beginning of the breeding season. A progestogen (CIDR®) was inserted for 11 days and a dose of PGF2α was applied two days prior to its withdrawal. Estrus detection started 12 hours after CIDR withdrawal. Blood samples were obtained during the supplementation period to measure oxidative status, antioxidant capacity, glucose and insulin, and up to 9 days after breeding to determine progesterone concentration. Pregnancy diagnosis was performed at 30 and 60 days post-breeding. An analysis of repeated measures of mixed effects and frequency analysis were carried out. Results: Inclusion of coffee pulp for a short period prior to breeding did not affect reproductive parameters, nor progesterone, glucose or insulin concentrations (p>0.05); however, antioxidant capacity increased, while lipid oxidation showed an opposite trend (p<0.05). Conclusion: Inclusion of up to 10% coffee pulp in the diet of ewe lambs for 16 days prior to breeding improves oxidative status without causing adverse effects on pregnancy, estrus or prolificacy. ResumenAntecedentes: La pulpa de café tiene un alto contenido de antioxidantes capaces de modificar el estado oxidativo en pequeños rumiantes. Sin embargo, a dosis elevadas y por un tiempo prolongado puede reducir la fertilidad. Objetivo: Determinar el efecto de dos niveles de inclusión de pulpa de café durante la sincronización del estro en variables reproductivas y el estado oxidativo de ovejas primerizas. Métodos: Se utilizaron 60 ovejas primalas Suffolk x Dorset fueron distribuidas en tres tratamientos en un diseño completamente al azar; T0: (n=20) con 1,5 kg de dieta integral, T1: (n=20) con 1,5 kg de dieta integral y 5% de pulpa de café, T2: (n=20) con 1,5 kg de dieta integral y 10% de pulpa de café. La suplementación se realizó por 16 días, previo a la sincronización del estro y hasta el empadre. El progestágeno (CIDR®) se insertó en las ovejas por 11 días y se aplicó una dosis de PGF2α dos días antes de su retiro. La detección de estro comenzó a las 12 horas post-retiro del CIDR®. Se obtuvieron muestras sanguíneas durante el periodo de suplementación para medir estado oxidativo, capacidad antioxidante, glucosa e insulina, y hasta 9 días posteriores al empadre para determinar las concentraciones de progesterona. El diagnóstico de gestación se realizó a los 30 y 60 días post-monta. Se realizaron anális...

“…It is well documented that oxidation stress increases at the time of parturition (Casamassima et al, 2012). Salinas et al (2016) reported that at the beginning of gestation, the antioxidant capacity in blood plasma of sheep decreases. A possible explanation is that the antioxidant concentration decreases, since it has been reported that the concentration of vitamin C, which is an antioxidant, decreases at the beginning of gestation (Salinas et al, 2017).…”

The objective of the study was to evaluate the reproductive efficiency and antioxidant status of ewes supplemented with two levels of vitamin C during oestrous synchronization and early gestation. Sixty-three ewes were allocated to three treatments, namely T0: control group; T1: 3 g vitamin C coated with ethylcellulose (Rovimix C ® , powder); and T2: 6 g vitamin C coated with ethylcellulose. The ewes received the dietary supplementation during an oestrus synchronization period and lasted until 18 days after breeding. The occurrences of oestrus, gestation, fecundity and prolificacy were measured. Blood samples were collected at various stages to determine antioxidant capacity and oxidative state, and progesterone, glucose and insulin concentrations. Percentage occurrence of oestrus and gestation was analysed using the Chi-Square test, prolificacy and fecundity by GENMOD, and blood tests by the PROC MIXED procedure. It was recorded that the concentration of vitamin C in plasma increased with the supplementation of 3 g and 6 g vitamin C. The antioxidant capacity was higher in T1 than in T0 and T2. Lipid oxidation, and glucose, insulin and progesterone concentrations were not affected. It is concluded that supplementation of 3 g vitamin C during oestrous synchronization and early gestation does not modify the reproductive responses of the ewes. However, the concentration of this vitamin in the blood increased and improved the antioxidant capacity of the animals.
