“…However this effect was not seen in experiment 2 (discussed above). The findings from experiment 1 are consistent with recent findings in goats [5,6,25] where it was reported that short-term nutritional supplementation improved oestrus and ovulation rate of anoestrous female goats in semi-arid north-central Mexico but not the proportion responding to the "buck effect".…”

“…Ordinarily, these two techniques are used individually and although occasionally used together there is little data evaluating their combined effectiveness. Consequently we set out to learn if they could be used together to improve the reproductive performance of sheep mated during seasonal anoestrus, as has been observed for goats [5,6].…”

“…Véliz et al (2006) also reported the importance of the female body weight in the response to the male effect; more than 98.0% of the females with moderate and high weights showed behavioral signs of estrus 15 days after the male introduction, against only 63.3% in the group with low body weight (P < 0.01). Santiago-Miramontes et al (2008) also mentioned the importance of nutritional supplements to the female ovarian response after the males had been introduced.…”

Organic and conventional management in a Parda Alpina dairy goat production system in northeastern Brazil

In this study, we compared organic and conventional management in a dairy goat production system in Angicos, Rio Grande do Norte, Northeastern Brazil. Twenty-six Parda Alpina dairy goats were used: 13 in organic management (OM) and 13 in conventional management (CM). The experimental design was completely randomized with two treatments and 13 repetitions. OM practices included estrus synchronization with the "male effect," an herbal-based treatment against endoparasitoses (an extract of lemon [Citrus limonum] and garlic [Allium sativum]) and the control of mastitis using the Embrapa Kit for manual milking with a rosemary pepper (Lippia sidoides) tincture. CM animals received synthetic hormones (Promone®, Prolise®, and Novormon®) for synchronization of estrus, ivermectin for endoparasitoses, and iodized alcohol for mastitis prevention aided by the Embrapa Kit for manual milking. No significant differences were observed between the management types in the pregnancy rate, FEC, FAMACHA© (Faffa Malan Chart) scores, physico-chemical composition of the milk, or somatic cell count (SCC). Both OM and MC had pregnancy rates of 61.54%. The mean values of the egg counts observed in the OM and CM were 24 and 35 eggs g -1 , respectively. The FAMACHA© scores were 1 or 2 and 2, 3, or 4 in OM and CM, respectively. The goats had average weights in OM of 48.53 kg and in CM of 55.92 kg. Milk production, fat, protein, lactose, total solids, and nonfat solids in OM (0.971 kg/day, 2,210, 2,322, 3,306, 7,866, 5,566, respectively) were slightly higher than those in CM (0.946 kg/day, 1,812, 1,812, 2.868, 6.74, 4.928). OM (904,860 cells/mL) and CM (1.02052 million cells/mL) SCC values were similar, with the OM within the acceptable range for milk goats. Organic management was equivalent to conventional management for weight gain, maintenance of animal health standards, reproductive and sanitary control, and milk quantity and quality, and is technically suitable for a dairy goat production system in semiarid conditions.

“…In fact, the proportion (18/20) of females that displayed estrous behavior was higher when they were left permanently in pens and grasslands with sexually active males than with sexually inactive ones (9/20; Rivas-Muñ oz et al, 2007). In addition, a high behavioral response (.90%) was also obtained when males remained in the open pen during the day while females grazed in open range (Rivas-Muñ oz et al, 2007;De Santiago-Miramontes et al, 2008;Fitz-Rodríguez et al, 2009).…”

Goat breeds from subtropical latitudes show different annual reproductive cycles. Some of them display large seasonal variations in their annual breeding season, while others display a moderate seasonality or sexual activity all year round. This reproductive seasonality causes seasonality of milk, cheese and meat productions and, as a consequence, induces wide variation in producer incomes. To solve this problem and provide methods allowing producers to breed animals during the anestrous period and stabilize production all year round, it is necessary to have a deep knowledge of their annual sexual activity and to identify the environmental factors controlling the timing of the annual reproductive cycle. Then, it is possible to build on these knowledge sustainable breeding techniques adapted to the environmental, economic and social characteristics of the local breeding system. In this review, I will illustrate this strategy through the example of our experiments in subtropical goats. First, we determined the characteristics of the annual breeding season in both male and female goats. Second, we identified the photoperiod as the major environmental factor controlling the timing of this annual breeding season. Third, we used the photoperiod to stimulate indirectly the sexual behavior of does. Indeed, we used photoperiodic treatments to stimulate the sexual activity of bucks during the non-breeding season. These sexually active male goats were then used to induce and synchronize the estrous behavior and ovulatory activity of anestrous females in confined or grazing conditions by using the 'male effect'. Under subtropical conditions, these results constitute an original manner to control the reproductive activity of local goats using the photoperiod combined with the 'male effect.'
