“…On the contrary, the deletion of goat MSTN gene will enhance the muscle protein synthesis and cell proliferation which contribute to an aggrandizement on the mass of muscle, then gain the body weight. Since the body height had a positive correlation with the body weight [54], the deletion of the MSTN gene was considered to have a positive effect on body weight. Additionally, we also hypothesized that the mutations of goat MSTN gene were related to the phenotype of other growth traits.…”

Myostatin (MSTN) gene, also known as growth differentiation factor 8 (GDF8), is a member of the transforming growth factor-beta super-family and plays a negative role in muscle development. It acts as key points during pre- and post-natal life of amniotes that ultimately determine the overall muscle mass of animals. There are several studies that concentrate on the effect of a 5 bp insertion/deletion (indel) within the 5’ untranslated region (5’ UTR) of goat MSTN gene in goats. However, almost all sample sizes were below 150 individuals. Only in Boer goats, the sample sizes reached 482. Hence, whether the 5 bp indel was still associated with the growth traits of goats in large sample sizes which were more reliable is not clear. To find an effective and dependable DNA marker for goat rearing, we first enlarged the sample sizes (n = 1074, Shaanbei White Cashmere goat) which would enhance the robustness of the analysis and did the association analyses between the 5 bp indel and growth traits. Results uncovered that the 5 bp indel was significantly related to body height, height at hip cross, and chest width index (p < 0.05). In addition, individuals with DD genotype had a superior growing performance than those with the ID genotype. These findings suggested that the 5 bp indel in MSTN gene are significantly associated with growth traits and the specific genotype might be promising for maker-assisted selection (MAS) of goats.

This study was carried out to document the pelvic and testicular biometric characteristics of Sahel goats. Record of body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference were obtained from 400 male and 600 female Sahel goats. All the goats were approximately 1.5 years old and weighing 14 to 18 kg, with body condition score of 3 or 4 (scale of 1-5). The mean bodyweight of Sahel bucks was 15.12 ± 1.10 kg while that of Sahel does was 13.22 ± 1.12 kg, height at withers in bucks and does were 52.22 ± 1.20 cm, and 48.13 ± 1.23 cm respectively. The scrotal length and circumference in Sahel bucks were 11.39 ± 1.12 cm and 17.95 ± 1.21 cm respectively. The external pelvic circumference in Sahel does was 55.13 ± 1.16 cm. There was significant (P<0.05) positive correlation between the body weight and body condition score in bucks (r=0.52) and in does (r=0.42). It was observed that there was weak but positive correlation between the body weight and height at withers (r=0.34), in bucks and in does (r=0.25; P <0.5). A low but significant positive correlation was found between the body weight and scrotal circumference r=0.28, (P<0.05) in bucks. There was a highsignificant positive correlation between the scrotal length and scrotal circumference r=0.66, (P <0.05). The external pelvic circumference in Sahel does was also significantly positively correlated with body weight r=0.40, (P<0.05) and with the body condition score r= 0.33, (P<0.05). In conclusion, the body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference of Sahel goats in Maiduguri were successfully determined, these parameters studied might serve as a bases for determining the breeding soundness of Sahel goats.

“…Goat meat production is among the important meat besides beef and mutton. Breeds such as Boer, Savannah, and Red Kalahari can adapt to different environmental conditions and grow rapidly with excellent carcass quality (Lu, 2001;Rahman et al, 2008b;Hifzan et al, 2015;Maynard, 2015). A good breeding program needs to be developed to maintain and continuously produce these breeds efficiently.…”

Study of sexual behaviours with different types of estrus synchronization protocols in Boer goats

2021

There is still a lack of information on estrus synchronization in goats. Understanding the estrus synchronization protocols and the subsequent effects is important to improve the efficiency of assisted reproductive technologies (ARTs) and subsequently would improve the breeding procedures. This study will help in determining the most suitable estrus synchronization protocol and understand better the effect on the sexual behaviour and hormonal effects in goats. A total of 127 Boer does were used and divided into three groups with different duration of CIDR insertion intravaginally either for 14 (two groups) or 9 days (one group). Approximately 0.5 ml Estrumate ® (PG) was administered intramuscularly to all groups at CIDR removal, and only groups PMSG14 and PMSG9 were administered with 200IU of Pregnant Mare Serum Gonadotropin (PMSG) intramuscularly. Estrus signs were observed at 4 h intervals and blood samples were collected for progesterone and luteinizing hormone determination. The percentage of does in estrus within 24 to 72 h post CIDR removal was significantly higher (P<0.05) in groups with PMSG compared to the group without the PMSG. The numbers of does display estrus signs within 24 to 28 h post CIDR removal were significantly higher (P<0.05) in group shorter period (9 days) compared to groups with 14 days CIDR. The P4 concentrations at 24 hours post CIDR removals and LH concentration was not significantly different (P>0.05) in all groups. The time of the LH peak in the group without the PMSG was significantly delayed (P<0.05) when compared to group 9 days CIDR and administered with PMSG. It is recommended to use the treatment for 9 days CIDR since the estrous cycle can be shortened.
