“…Male kids exceeded females significantly (P<0.05, Table 1) in their birth weight (2.4 vs. 1.8 kg), weaning weight (12.5 vs. 7.1 kg), weight at 6 months (16.5 vs. 10.6 kg), weight at 9 months (21.2 vs. 14.7 kg), and pre-weaning (111 vs. 57 g/d), postweaning (48 vs. 42 g/d) and total growth rates (69 vs. 48 g/d). It is generally confirmed by many workers that male kids are significantly heavier and have a higher growth rate than females [21, [27][28][29]. The superiority of males over females in terms of body weight and daily gain in weight might be attributed to androgen acts as an anabolic hormone [27,28].…”

The purpose of this experiment was to investigate the impact of maternal pre-and post-partum feed supplementation, under farm conditions, on goat kid's growth, follicle traits and fiber production. The design of experiment was supplementation from 2 months pre-partum to 2 months post-partum with 3 nutritional groups (8 does each). The first does group (GI) was fed black barley at 250 g/doe/day (traditional farmer’s practice), whereas does of the second (GII) and third (GIII) groups were fed concentrate diet at 500 and 750 g/doe/day, respectively. Results revealed that birth weight from GII and GIII was significantly (P<0.05) higher by 22% (2.3 vs. 1.8 kg) than that of GI. Weaning weight and marketable live weight traits, growth rates, follicle traits except primary follicles, and fiber characteristics were significantly (P<0.05) higher in (GIII) followed by (GII) and then (GI). Moreover, goat kids of the GIII attained significantly (P<0.05) 37% (16.9 vs. 10.7 kg) and 26% (16.9 vs. 12.5 kg) more marketable live weight compared with GI and GII, respectively. Also, goat kids of the GIII produced 32% (813.3 vs. 553.3 g; P<0.05) and14% (813.3 vs. 703.3 g; P>0.05) higher fleece weight than that of GI and GII, respectively. Additionally, body weight traits, growth rates, and fiber characteristics were significantly (P<0.05) affected by sex of birth. In conclusion, supplementation with an increased level of feeding concentrate pre-and post-partum of Maraz goats showed a significant (P<0.05) positive effect on productive performance of their kids in comparison to the traditional farmer’s practice.

“…This information partially coincides with the report of Aktas et al (2015), who describe that the highest growth rate in indigenous Turkos hair and Honamli goats are found between 20-40 and 60-60 days. These findings are extremely interesting, because by identifying critical growth periods, feeding management strategies that optimize productivity can be developed and implemented (Omotosho et al, 2020). Likewise, as the animal grows and transforms, its proportions change, both internally and externally.…”

The aim was to evaluate the effect of coat color, sex and age on body composition in local kids from northern Mexico. Eighty-three local kids between 1 and 30 days of age were selected. They were assigned to groups according to coat color (dark and light), sex (males and females) and age (1=1 to 10; 2=11 to 20 and 3=21 to 30 days). Pigmentation of skin, hooves, mucous membranes, morphostructural characteristics, live weight and 14 zoomometric measurements were evaluated. A predominant phenotype was found of animals without mammels, beards, without pigment in the skin and hooves, with horns, horizontal ears and pigmented mucous membranes. The highest values (p < 0.05) for live weight (PV), neck length and width (LCue, ACue), chest circumference (CPe) and flank depth (PFl) were found in dark kids. The highest value (p < 0.05) in ear length (LO) was observed in light-colored kids. When considering sex, the highest values (p < 0.05) were observed in males for all traits, except for length and width of face (LCa, ACa) and width of ears (AO), height at withers (ACruz), PFl and sacrolumbar height (ASL), which were not different (p > 0.05). When considering age, the highest values were found in all traits for group 3. All variables were positively and significantly correlated. The variables showing the greatest magnitude of change in the first 20 days of age are PV (+40 %), LCa, LCor, CPe (+15 %) and LCue, ACruz, PFl, leg length (+10 %), while between 20 and 30 days of age the magnitude of change generally decreases. It is concluded that coat color, sex and age significantly influence the body composition of local kids from northern Mexico, which may have implications in the selection and marketing thereof.

“…The does selected in the study were in first parity and non-pregnant. The Kalahari Red goat is an efficient breed because it feeds on plants and grass and requires low management and care (Omotosho et al, 2020). The animals were managed under an extensive farming system in which they were allowed to go out in the morning to graze and returned to their rotational camps in the afternoon.…”

Principal component analysis (PCA) is a vital statistical technique for defining the morphological structure of livestock but has not been used in South African Kalahari Red goats. Thirteen morphometric traits and eleven body indices from two hundred and ninety-six (296) South African Kalahari Red goats (269 does and 27 bucks) aged 2–3 years were used to define morphological structure using PCA. The coefficient of determination (R2), root mean square error (RMSE), Akaike’s information criterion (AIC), Mallows' Cp-statistic (Cp), and coefficient of variation (CV) were used to select the best fit model. Body weight was correlated with all morphometric traits in both sexes. The first two principal components explained 87.31% of the variation in measurements from male goats and 62.32% of the trait variation in the females. The inclusion of head length, body length, canon circumference, rump length, rump width, body condition score, wither height, and rump height increased the accuracy to 98% with smaller RMSE (2.42), AIC (55.35), Cp (10.00), and CV (3.98), and the use of PC1 and PC2 included 94% of the variation (RMSE, 3.62; AIC, 72.26; Cp, 3.00; CV, 5.94 in males). In females, the inclusion of all morphometric traits included 87% of the variation (RMSE, 2.93; AIC, 590.63; Cp, 13.00; CV 5.87). The use of PC1 and PC2 included 82% of the variation (RMSE, 3.41; AIC, 663.60; Cp, 3.00; CV, 6.84). PCA can therefore be used in breeding programs to define the morphological structure of South African Kalahari Red goats with a severe reduction in the number of morphometric traits to be recorded.
