Effect of Social Rank upon Estrus Induction and Some Reproductive Outcomes in Anestrus Goats Treated With Progesterone + eCG

We evaluated the possible role of the social rank [R] (i.e., low—LSR, middle—MSR, or high—HSR) in anestrus goats exposed to a P4 + eCG [D] (i.e., 100 or 350 IU) estrus induction protocol (EIP). Adult, multiparous (two to three lactations), multiracial, dairy-type goats (Alpine–Saanen–Nubian x Criollo goats (n = 70; 25°51′ North) managed under stall-fed conditions were all ultrasound evaluated to confirm anestrus status while the R was determined 30 d prior to the EIP. The variables of estrus induction (EI, %), estrus latency (LAT, h), estrus duration (DUR, h), ovulation (OVU, %), ovulation rate (OR, n), corpus luteum size (CLS, cm), pregnancy (PREG, %), kidding (KIDD, %), and litter size (LS, n) as affected by R, D, and the R × D interaction, were evaluated. While OVU and CLS favored (p 0.05; 38.5%) KIDD. However, EI, LAT, DUR, OR, and PREG were affected by the R × D interaction. The HSR group had the largest (p < 0.05) EI % and DUR h, irrespective of D. The shortest (p < 0.05) LAT occurred in D350, irrespective of R. While the largest (p < 0.05) OR occurred in HSR and MSR within D350, the HSR + D350 group had the largest PREG (p < 0.05). These research outcomes are central to defining out-of-season reproductive strategies designed to attenuate seasonal reproduction in goats

Dry matter yield and quality of some mediterranean annual legumes

El objetivo de este estudio fue evaluar la producción y calidad forrajera de variedades locales de algarroba (Vicia monanthos), almorta (Lathyrus sativus), guisante forrajero (Pisum sativum), veza común (Vicia sativa),alverjón (Vicia narbonensis) y yero (Vicia ervilia). El estudio se realizó en tres localidades de la provincia de Albacete, España, durante tres años consecutivos de cultivo. Los muestreos se realizaron en abril, junio y julio y en cada muestra se determinaron los parámetros cualitativos, materia seca (% MS), proteína bruta (% PB),fibra ácido detergente (% FDA), fi bra neutro detergente (% FDN) y energía metabolizable (Mcal) y a partir de ellos la producción (kg MS/ha). En el muestreo de abril la especie de mayor rendimiento (P = 0,05) fue el yero (1.127 kg MS/ha, 20,98% PB y 2,327 Mcal/kg MS) seguido de veza común (924 kg MS/ha, 23,01% PB 2,498 Mcal/kg MS). En el muestro de junio las especies de mayor rendimiento (P = 0,05) fueron vicia común (1.895 kg MS/ha, 20,01% PB y 2,247 Mcal/kg MS) y el yero (1.802 kg MS/ha, 16,12% PB y 2,033 Mcal/kg MS). En julio también fueron el yero (2.880 kg MS/ha, 13.98 % PB y 1,906 Mcal/kg MS) y la veza común (2.777 kg MS/ha, PB 14,97% y 2,043 Mcal/kg MS) las especies de mayor rendimiento (P = 0.05). Nuestros resultados indican que en las condiciones de del estudio el yero y la veza común fueron las especies de más productivas y por tanto de mayor interés como forraje, desde el fi nal del período vegetativo hasta la plena madurez

Effects of Dietary Supplementation of Garlic and Oregano Essential Oil on Biomarkers of Oxidative Status, Stress and Inflammation in Postweaning Piglets

The effects of two different concentrations of micro capsuled oregano essential oil (OEO) and purple garlic powder on biomarkers of oxidative status, stress, and inflammation, as well as on average daily gain (ADG) and feed conversion ratio (FCR), were evaluated in piglets during the postweaning period. The trial was carried out with 300 crossbred pigs of 21 days of age fed with different concentrations of OEO and purple garlic powder and ZnO. Saliva and serum samples were taken to evaluate a panel of biomarkers of oxidative status, stress, and inflammation. OEO and garlic powder at 0.4% did not produce significant changes in C-reactive protein (CRP) and cortisol and yielded higher levels of the antioxidant biomarker CUPRAC in serum than higher doses (p &lt; 0.01); they yielded a better ADG than the control and ZnO diets. OEO and garlic powder at higher concentrations than 0.4% showed higher concentrations of CRP (p &lt; 0.05). Overall, doses of OEO and garlic powder at 0.4% did not lead to inflammation, stress, or negative changes in oxidative biomarkers in piglets during the postweaning period and gave better productive performance than the control and ZnO diets. High doses of OEO and garlic powder were ineffective and could negatively affect the animals. Therefore, our results highlight the importance of the dose used when OEO or garlic are supplemented to piglets
