“…Orgeur et al (1990) reported that in intensive goat production systems, levels of aggression are higher than those compared to semi-intensive and extensive systems. This was also verified by Barroso (2000) who reported that the frequency of aggressive interactions were higher among goats that were kept indoors than among goats on pastures, probably because of differences in space availability that was more limited indoors. Goats from the present study showed high anxiety for the hours that preceded food delivery, as well as that the proximity between the stalls where they were confined contributed to aggressive behaviour among them.…”

The ethogram description of confined goats is an alternative that helps identify animals' behaviour, their main behavior and the importance of developing production systems that provide better welfare conditions. This paper aims to describe the ethogram of three genetic groups of confined goats: Azul, Moxotó and Graúna, through monitoring video images, using 9 animals kept in individual pens, monitored by video cameras mounted on the roof of each pen. As for the design and description of ethogram, 810 hours of video image were recorded and analysed, these being from being nine hours a day periods; three in the morning, afternoon and night. We identified 34 visual behaviours, which were grouped into eight categories according to their functional character: food = 4), social interaction (n = 6), displacement (n = 2), resting (n = 3), grooming (n = 4), neutral position (n = 3), bipedal (n = 5) and other activities (n = 7). In conclusion, behaviors described in the ethogram were similar for all three genetic groups. Goats conduct their daily routine with sequences of behaviour that involve eating (food intake or selection) and resting or ruminating, with social interactions and other activities having happened more frequently in the afternoon and at that time in the afternoon before being provided with food.

“…This negative effect of undernutrition on body weight and reproductive function may depend on the social status of the females. Thus, the low body weight of some goats in our study may have reflected a lower food intake in these animals because of their lower social status [15,16]. In addition, dominant goats do compete better to gain contact with the males and consequently impair the response to the male effect in subordinate females [17].…”

Positive correlation between the body weight of anestrous goats and their response to the male effect with sexually active bucks

et al. 2006

-In the present study, we analyzed the results of two years of response to the male effect in seasonally anestrous goats to investigate whether the activation of female reproductive activity by the male effect is related to the body weight of the females. Seventy-nine adult female Mexican mixed breed goats were used. The anestrous females were exposed during 15 days to sexually active males, and were classified into three categories according to their mean body weight ±SD (42 ± 9 kg) (Light: ≤ 33 kg, n = 19; Medium: 34-50 kg, n = 46; Heavy: ≥ 51 kg, n = 14). More than 98% of the goats from the Medium and Heavy groups showed at least one estrus behavior within the first 15 days following the introduction of the bucks, versus only 63% of the females from the Light group (P < 0.01). The interval between the introduction of the males and the onset of estrus behavior was longer in the females of the Light and Medium groups (4.2 ± 0.8 and 3.3 ± 0.3 days) than in the females of the Heavy group (2.0 ± 0.2 days; P < 0.03). Also, body weight was negatively correlated with latency to first estrus (Spearman r = −0.57; P < 0.001). These results are in agreement with the hypothesis that the ability of anestrous goats to respond to the male effect is positively influenced by their body weight. seasonality / live weight / estrus induction / teasing / body condition / biostimulation / subtropics
