I48-R154-article-41342025-02-12T21:59:02Z Effect of concentrate supplementation on calf weight, pregnancy and body condition of cows from Lower Paraguayan Chaco Efecto de la suplementación sobre el peso del ternero y la preñez y condición corporal de vacas del Bajo Chaco Paraguayo Pineda, V. Valiente, O. L. Cows calves supplement weight gain corporal condition pregnancy percentage Vacas terneros suplementación ganancia de peso condición corporal porcentaje de preñez The objective of the study was to evaluate the effect of concentrate supplementation of suckling calves on their weight gain, as well as the pregnancy percentage and body condition of the cows, which was carried out in an establishment located in the Department of Presidente Hayes, Lower Paraguayan Chaco. Thirty unweaned calves from multiparous cows between 2 and 3 months of age, were used. They were grouped into two treatments (T) of 15 calves and 15 cows for each treatment (T1: calves not supplemented and T2: calves supplemented), which grazed on a native pasture during the assay. The supplement consisted of a concentrate with 20% crude protein and 3 Mcal/kg of metabolizable energy, which was offered for 120 days. On each T, a Brangus bull was assigned to service the cows for 70 days. The average daily weight gain of the calves was 0.464 and 0.708 kg for T1 and T2, respectively, the difference being statistically significant (p<0.05). On the other hand, the pregnancy percentage was identical in both groups (7%). However, the number of cows with the highest final body condition (FBC3) increased in T2. It can be concluded that the most important effect was the improvement in the daily weight gain of the calves that received the supplementation and the increase in the number of cows with FBC3. El objetivo del estudio fue evaluar el efecto de la suplementación de terneros lactantes sobre su ganancia de peso, así como el porcentaje de preñez y condición corporal de las vacas. La investigación fue realizada en un establecimiento ubicado en el Departamento Presidente Hayes, en el Bajo Chaco Paraguayo. Se utilizaron treinta terneros de 2 a 3 meses de edad, crías de vacas adultas multíparas, que se agruparon en dos tratamientos (T) de 15 terneros y 15 vacas por cada uno (T1: terneros no suplementados y T2: terneros suplementados, ambos pastando sobre una pradera nativa en forma continua). El suplemento utilizado fue un concentrado con 20% de proteína bruta y 3 Mcal/kg de energía metabolizable, que se ofertó durante 120 días. En cada T se asignó un toro tipo Brangus para el servicio de las vacas, por 70 días. La ganancia diaria promedio de peso de los terneros fue de 0,464 y 0,708 kg para T1 y T2 respectivamente, siendo la diferencia estadísticamente significativa (p<0,05); no así el porcentaje de preñez, que fue idéntico en ambos grupos (7%). Sin embargo, en T2 aumentó la cantidad de vacas con la condición corporal final más alta (CCF3), diferencia que fue estadísticamente significativa (p<0,05). Se concluye que los efectos más importantes fueron la mejoría en la ganancia diaria de peso de los terneros que recibieron la suplementación y el aumento de la cantidad de vacas con CCF3.
