RESUMEN.
El objetivo del presente trabajo fue comparar durante la estación reproductiva la utilización de esponjas intravaginales de medroxiacetato de progesterona (MAP) sin la asociación de eCG con una dosis de un análogo de prostaglandinas (PG) en cabras lecheras que no habían manifestado celo durante los cinco días (d) previos. Sesenta y siete cabras, adultas y secas, Criolla (C), Anglo Nubian (N), Saanen (S) y mestizas (M) se asignaron al azar según sus genotipos a los siguientes tratamientos: Grupo-MAP (n=36): esponja intravaginal conteniendo 60 mg de MAP durante 14 d o Grupo-PG (n=31): una dosis de 200 µg de delprostenate a cabras que no habían manifestado celo durante los cinco días previos. El celo se detectó a corral dos veces/d durante los cinco días post-tratamiento y una vez/día hasta 22 d después. Las cabras fueron servidas por monta natural controlada en corral al momento del celo detectado y 24 horas (h) después. Los resultados reproductivos fueron analizados usando modelos generalizados (procedimiento GENMOD de SAS). El modelo incluyó los efectos del tratamiento, el grupo genético (C y M vs. N y S) y su interacción. El tratamiento hormonal no influyó en la expresión de celo (100%), ni en la tasa de no retorno en celo a los 21 d (GrupoMAP: 68% vs. Grupo-PG: 54%), como tampoco sobre la fertilidad (cabras paridas/cabras tratadas: Grupo MAP: 55% vs. Grupo-PG: 46%) y sobre la prolificidad (crías nacidas/cabras paridas: Grupo-MAP: 1,47 vs. Grupo-PG: 1,33). El grupo gené- tico solo afectó la prolificidad, C y M: 1,2 vs. N y S: 1,51 (P=0,054). Un alto porcentaje de cabras de ambos grupos retornaron en celo 5-10 d después (ciclos estrales cortos): Grupo-MAP: 70% vs. Grupo-PG: 75%.
ABSTRACT.
The aim of the present work was to compare the use of intravaginal sponges containing medroxiprogesterone acetate (MAP) with a single dose of prostaglandine (PG) on dairy goats which had not shown estrous signs during the previous five days (d) for estrus synchronization during the reproductive season. Sixty-seven adult non-lactating Criollas (C), Anglo-Nubian (N), Saanen (S) and Crossbred (Cr) goats were randomly assigned taking into account their genotype to: Group-MAP (n = 36) intravaginal sponges containing 60 mg of MAP during 14 d and Group-PG: (n = 31) 200 ?g of delprostenate to goats showing no signs of estrus during previous five days. Estrus was detected in an pen twice a day during five days after treatment and once a day thereafter during 22 d. Goats were bred in a pen by natural service after oestrus detection and 24 hours (h) later. Data were analyzed using the generalized model (PROC GENMOD of SAS). The model included the effects of treat-ments, genetic group (C and Cr vs. N and S) and their interaction. Hormonal treatments did not influence the 100% of goats showing estrus during 120 h after treatments (100% for both groups), non return to estrus after 21 d (Group-MAP: 68% vs. Group PG: 54%) or kidding rate (kidding goats/treated goats: Group-MAP: 55% vs. Group PG: 46%), or litter size (number of kids/kidding goats: Group-MAP: 1.5 vs. Group-PG: 1.3). The genetic group only influenced the litter size (C and Cr: 1.1 vs. N and S: 1.5; P=0.054). A great percentage of goats of both groups returned to estrous 5-10 d later (short oestrus cycle): Group-MAP: 70% vs. Group-PG: 75%. MenosRESUMEN.

Abstract:Temperate-type, summer-active cool-season perennial grasses are frequently exposed to dry spells during the warm season due to the high atmospheric demand and fast soil desiccation. Since water availability is essential for sward nitrogen (N) uptake and most mineral N is located in the topsoil, water stress may hinder sward N nutrition if it reduces N supply. In hydro-halomorphic soils, imbalances between soil N supply and sward N demand during summer could be further aggravated by, first, the limited water holding capacity of the topsoil, and second, potential availability of water from deep, N-poor soil horizons that are kept moist by a shallow water table. The aim of this work was to quantify the effect of N and water availability on N status and productivity of temperate-type perennial swards growing in a hydro-halomorphic soil of the Flooding Pampa. During two consecutive years, shoot and root dynamics, as well as radiation capture, N nutrition index (NNI), soil water availability and leaf water potential were followed over six weeks long mid-summer regrowths of old stands (>9 years) of temperate-type tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] sown on a typical Natraqualf soil in Balcarce, Argentina. Swards were either rainfed or irrigated and fertilized with either 40 or 200 kg de N ha?1. Root systems were large (5.8?9.3 Mg DM roots ha?1), but concentrated mostly in the 0.2 m topsoil (66%?75% of root biomass or length). Despite invariably high available water below 0.4 m throughout both experimental periods, rainfed swards faced transient episodes of water stress whenever the upper soil layer dried out. Tall fescue swards were strongly co-limited by water and N during summer, showing comparable, very high responses to both N addition and irrigation. Further, forage yield showed synergistic increases when swards received both supplemental water and N simultaneously. This was mainly due to consistent synergistic responses in radiation use efficiency and leaf lifespan. Sward NNI was depressed only by an historically severe drought but was not altered when water stress intensity was lower, close to average for the season in the area. Therefore, the major causes of typically low summer productivity of temperate-type tall fescue growing in hydro-halomorphic soils of the Flooding Pampa are the intrinsic effects of low N and low water availability, with only uncommonly extreme water stress episodes reducing yield indirectly through an aggravation of crop N status.
