Factors affecting growth and body condition of goats livestock in the semi-arid region of Formosa

The aim of this study was to determine the effect of kidding season, birth type, and sex on maternal body condition under a traditional extensive system in semi-arid Formosa. Birth weight (BW) and daily weight gain (DWG) in kids up to 40 days of age were assessed. Body condition score (BCS) was meas...

R. extensive system goats nutritional management sistema extensivo ganado caprino manejo nutricional The aim of this study was to determine the effect of kidding season, birth type, and sex on maternal body condition under a traditional extensive system in semi-arid Formosa. Birth weight (BW) and daily weight gain (DWG) in kids up to 40 days of age were assessed. Body condition score (BCS) was measured in dams at kidding and 30 ± 5 days post-kidding. A factorial design was carried on with 3 factors (sex, birth type, and kidding season), with two levels each (male-female, single-twin, and autumn-spring) along with their interactions. BCS and BW were analyzed using ANOVA (p<0.05), while DWG was assessed through linear regression and MLM (p<0.05). No significant differences were observed in BCS of goats at kidding; however, differences emerged at 30 ± 5 days post-kidding, with higher values in autumn (1.9 BCS) compared to spring (1.5 BCS). Males BW (2.94 kg) were higher than females BW (2.66 kg), and single kiddings (3.22 kg) were higher than double kiddings (2.39 kg). No significant differences in DWG were observed between males (0.11 kg day-1) and females (0.11 kg day-1). However, DWG was significantly higher in kids born from single births (0.13 kg day-1), than those born from double births (0.09 kg day-1). Additionally, kids born in autumn showed a significantly higher DWG (0.13 kg day-1) than those born in spring (0.09 kg day-1). Season influenced the BCS of dams at 30 ± 5 days post kidding. Sex and birth type affected BW, while birth type and kidding season influenced DWG. El objetivo de estudio fue determinar el efecto de la época de parición, el tipo de parto y el sexo sobre la condición corporal de las madres, bajo un sistema extensivo tradicional en el semiárido de Formosa. En las cabras se registró la condición corporal (CC) al momento del parto y a los 30 ± 5 días post pariciones, mientras que en cabritos se evaluó el peso al nacimiento (PN) y la ganancia diaria de peso (GDP) hasta los 40 días de edad. Se utilizó un diseño factorial con 3 factores (sexo, tipo de parto y época de parición), con 2 niveles cada uno (macho-hembra, simple-doble y otoño-primavera) y sus interacciones. La CC y el PN se analizaron con ANOVA (p<0,05) y la GDP con regresión lineal y modelo lineal mixto (p<0,05). No se observaron diferencias en la CC de las cabras al momento del parto, pero si a los 30 ± 5 días post pariciones siendo mayor en otoño (1,9 CC) que en primavera (1,5 CC). El PN de los machos (2,94 kg) fue mayor que el de las hembras (2,66 kg), al igual que los partos simples (3,22 kg) en comparación con los partos dobles (2,39 kg). No se encontraron diferencias en la GDP entre machos (0,11 kg día-1) y hembras (0,11 kg día-1). Sin embargo, la GDP fue mayor en cabritos nacidos de partos simples (0,13 kg día-1) (p<0,05), en relación a los nacidos de partos dobles (0,09 kg día-1). Del mismo modo, los nacidos en otoño (0,13 kg día-1) presentaron mayor peso que los nacidos en primavera (0,09 kg día-1) (p<0,05). La época influyó en la CC de las madres a los 30 ± 5 días post pariciones. El sexo y el TP afectaron el PN, mientras que la GDP se vio influenciada por el TP y la época de parición.
