On-farm performance evaluation of Maale goats under agro-pastoral management in Southwest Ethiopia
Int. J. Agril. Res. Innov. Tech. 12(2): 7-13, December, 2022
This study was conducted in Maale district Southwest Ethiopia with the objective of evaluating the productive and reproductive performance of Maale goats under agro-pastoral management conditions. Thirty households that have flocks numbers of more than ten were purposely selected and monitored from July 2018 to July 2019. Growth data of birth weight, three month, six month, nine month and yearly weight; birth type and parity were collected. The data were analyzed using the General Linear Model (GLM) procedure of SPSS (21). The overall mean birth weight of the kids was 2.57±0.05 kg (males 2.68±0.07 and females 2.47±0.07 kg). The weaning and six months weight of kids was significantly different (p<0.05) between sexes of kids with 7.66±0.25 and 6.90±0.23 kg for male and female kids, respectively. The average body weight of males and females for six months; nine months and yearly were 11.57±0.30, 10.42±0.28; 15.42±0.27, 14.69±0.25 and 19.03±0.28, 18.43±0.25 kg, respectively. The birth type showed a significant (p<0.05) difference in birth weight. The result further indicated that the weaning weight of single and twin kids was highly significant (p< 0.001) and recorded as 7.66±0.25 and 6.90±0.23 kg, respectively. The overall pre-weaning average daily gain was 51.64±1.89 g day-1 (54.47±2.81 male and 48.93±2.53 g day-1 female). The birth type was significantly (p=0.01) different in preweaning growth rate and recorded 57.24±1.63 and 45.24±3.59 g day-1 for single and twin kids, respectively. Twins had higher post-weaning average daily gain than single and recorded as 43.61±1.48 and 40.76 ±0.70 g day-1 , respectively. It was concluded that, along with other management interventions, the reproduction and growth performance of Maale goats is reasonably good and suited for community-based breeding strategies and higher performance could be expected.
On-farm monitoring of growth performance of indigenous goat in Amhara region of Ethiopia
Online Journal of Animal and Feed Research
The study was conducted in Amhara region of Ethiopia, with the objective of characterizing the goat husbandry practice and on-farm monitoring of growth performance. The data were collected by interviewing 180 sample households who are selected purposively from three agro ecologies using semi-structured questioner. Besides, on farm monitoring of growth performance of 60 kids owned by farmers was done for three months. The data was analyzed using SPSS (version 20). Majority of households (68.9%) have an experiences of feeding crop residue for their goat and faced feed shortage mainly during dry season (65.6%). The main source of water for goat was river which is 51.1% in wet season and 88.9% in dry season. 51.7% of goat keepers had a separate goat house. The major disease reported were anthrax (40.6%), goat pox (26.7%) and foot and mouth disease (12.8). Purpose of goat keeping was mainly for income source (62.8%). 84.4% of the goat owners are experienced selection of male and female animal for production purpose. Body length and height (60.6%) and color (34.4%) were used as major selection criteria. Higher kidding was reported during months of October (20.55%), November (39.44%) and December (18.88%). Drought (42%), shortage of feed and water (38.5%), disease and parasite (16%), inconvenient climate condition (2%) and lack of breeding male (1%) were reported as major problems in the breeding objective. The overall birth weight, 60 days and 90 days weight of kids was 1.69±0.08 kg, 7.45±0.41 kg and 12.02±0.25 kg, respectively. The survival rate of kids up to 90 days of age was 74%. The production system of the area was characterized by mixed crop-livestock farming system on which crop residue was the main feed source of the goats as other livestock species. Even though the current productivity of goats in the area is fairly good, full potential need to be exploited by improving husbandry practices, applying appropriate disease prevention methods and applying strategic forage development and feeding practices.

Journal of Biology, Agriculture and Healthcare, 2018
The study was conducted at lowland part of Konso district to evaluate the performance of Woyto-Guji goat breed managed under traditional management systems. Data on growth performance was collected from 398 kids for two years. The mean values for birth, weaning, six month, nine month and yearling weight of kids obtained were 2.15±0.50, 9.32±2.28, 13.32±1.59, 15.89±2.94 and 18.89±2.86 Kg, respectively. Sex of does, birth type, color type, birth season and parity of kids significantly affected at all ages considered. Male kids were heavier at birth, nine months and yearling weight than females while twin born kids were lighter at all levels of age categories than their single born kids counterparts. Kids born during dry seasons were lighter in body weight from weaning up to yearling weight while white colored kids showed lighter body weight than black and brown colored ones at nine month and yearling weights. Kids from first parity does were lighter at birth of age than kids of higher...

Legesse, G., Abebe, G. and Goetsch, A.L. 2006. Performance and harvest measures of Somali and Arsi-Bale goats managed under three feeding systems in Ethiopia. J. Appl. Anim. Res., 30: 5-12. Forty-eight intact male goats, approximately 9 months of age, were used in an 84-day experiment to determine effects and interactions of genotype [27 Arsi-Bale and 21 Somali, with mean initial body weight (BW) of 14.1 and 15.9 kg, respectively (SE=0.39)1 and feeding system (intensive, semi-intensive and extensive) on growth performance and harvest mensures. Goats on the intensive (I) treatment were confined in individual pens and fed Rhodesgrass hay supplemented with 300 glday (air-dry) of a concentrate mixture; semiintensive (S) goats grazed grass pasture for 7 h lday and were supplemented with 300 glday of concentrate; and goats on the extensive (E) treatment grazed grass pasture for 8 h daily. There were no significant interactions between genotype and feeding system. Average daily gain (ADG) ranked (Pe0.05) S > I > E (54, 32, and 5 g) and was greater (Pc0.06) for Somali than for Arsi-Bale goats (34 us 27 g). Hot carcass dressing percentage among feeding systems was lowest (Pc0.05) for E (42.6, 43.3 and 38.8% for I, S and E, respectively). Carcasses of Somali goats were lower (Pe0.05) in separable lean tissue (55.3 us 58.9%) and higher in fat (PcO.05; 14.0 us 11.0%) compared with Arsi-Bale carcasses. Carcass separable lean concentration ranked (P<0.05) S (62.2%) > I (57.5%) > E (51.6%), fat among feeding systems was greatest (P<0.05) for I (15.3, 11.2 and 10.9% for I, S and E, respectively) and bone was greatest (Pe0.05) for E (27.3, 26.6 and 37.5% for I, S and E, respectively). I n conclusion, ADG of male Somali and Arsi-Bale goats was similarly affected by the different feeding systems, with Somali goats yielding greater final BW than Arsi-Bale as a function of both greater initial BW and ADG during the experiment. Feeding system can impact not only growth performance but also carcass characteristics that may influence consumer appeal.

Asian Journal of Animal Sciences, 2015
The study was conducted to evaluate the growth performance of Boer-Central Highland Goats (CHG) cross kids at Sirinka Agriculture Research Center SARC. A total of 510 kids were used for the analysis of least square mean of birth weight, weaning weight, six month weight and yearling weight. The overall least square mean of birth weight, weaning weight, six month weight and yearling weight were 2.68±0.02, 9.82±0.17, 13.54±0.20 and 19.53±0.38 kg, respectively. The body weight gained from birth to weaning, weaning to six month and birth to yearling were 78.67±1.53, 37.27±1.85 and 33.01±0.77 g dayG 1. Birth type and year of birth of kids have significant effect on birth, weaning, six month and yearling weight. The birth and weaning weight of the present study had have higher than local breed of Abergelle, Central highland goats, Boran Somali and rift valley. When the age advanced to six month and yearling, the weight were comparable to central highland goats and little bit higher than Abergelle and Boran Somali. For future study, it will needs on farm and on station evaluation with better feeding management to see their genetic potential.
Growth Performance of West African Dwarf Goats Reared in the Transitional Zone of Ghana
Asian Journal of Animal Sciences, 2015
The West African Dwarf (WAD) goats are the predominant breed of goats in Ghana. The present study aimed at assessing the growth performance (Birth weight-BWT, Pre-weaning growth rate-PREWGR, Weaning weight-WWT, Post-weaning growth rate-POSWGR and Yearling weight-YWT) of WAD goats reared in the transitional zone. About 809 breeding records from 2005-2012, live weight and linear body measurements (of 325 animals) were collected on WAD goats and subjected to GLM procedure to determine the fixed effects of sex, type of birth, season of birth and year of birth on growth performance. The fixed effects of sex and age on body measurements were also tested and then regression analysis done with body measurements. The sex of kid had significant effect (p<0.05) on pre-weaning growth rate and weaning weight, with males recording 32.42 g dayG 1 and 5.30 kg and females recording 31.75 g dayG 1 and 5.21 kg, respectively. Only birth and weaning weights were significantly (p<0.01) affected by type of birth as single born kids recorded highest values for BWT (1.56±0.02) and WWT (5.49±0.03). Kids born in the rainy season had significantly (p<0.05) higher values for POSWGR and YWT. The influence of year of birth was significant (p<0.05) on all growth parameters.

Objective: The present study aimed to evaluate the early growth performance of three Ethiopian goat populations (Bati, Borana and Short-eared Somali) from birth to 180 days and the influence of non-genetic factors such as sex, gemellarity and parity as well as goat ecotype on body weight (BW) and average daily weight gain (ADWG). Methods: A total of 350 heads of breeding does (113 Bati, 137 Borana and 100 Short-eared Somali) were used, and the kids were monitored for 1 year at birth, 30, 90 and 180 days of age. A total of 125 household flocks (46 Bati, 48 Borana and 31 Short-eared Somali) were monitored. Results: The birth BW of Bati (2.71 ± 0.04 kg; n = 139), Borana (2.36 ± 0.05 kg; n = 123) and Short-eared Somali (2.15 ± 0.08 kg; n = 46) remained significantly different (p < 0.01) in all successive observations until 180 days (16.31 ± 0.02, 13.9 ± 0.22, 13.75 ± 0.36, respectively). In overall, the sex of kids, gemellarity and parity of doe factors influenced the kid BW and ADWG during the early growth period mainly until 90 days, and consistently in Bati goat ecotype. In consequence, higher (p < 0.05) BW and ADWG were observed in males and singletons than in females and twins, respectively. In conclusion, our study confirms that non-genetic factors genetic affect these three Ethiopian goat ecotypes. The relative high BW of Bati goats suggest that this ecotype is profitable to improve growth performance using genetic selection.

The study, aimed to investigate indigenous goats’ husbandry practices, productive and reproductive performances, and constraints, was conducted in Ahferom district of central Tigray, Northern Ethiopia. Two peasant associations from midland and one from the lowland in the district were purposively selected based on their potentiality. Simple random sampling technique was employed to select 147 smallholder goats’ keepers. A pretested semi-structured questionnaire was used to gather data. Focus group discussions (FGDs) were also held with knowledgeable farmers and key informants. The collected data were analyzed using SPSS statistical software Version 28.0. In the study area, goats were kept by farmers for sale (52.5%), home consumption (24.4%), saving (13.1%), manure (10%), and prestige (1.0%) in the midland. Nevertheless, goats were kept for sale (33.3%), home consumption (33.3%), saving (12.5%), manure (16.6%), and prestige (4.1%) in the lowland. Goats were mainly dependent on browsing plants in both wet and dry seasons. The overall sources of water in the study area were water wells (40.1%), hand pumps (32.7%), and ponds (27.2%). Most (89.8%) farmers used separate houses for their goats. The mean amount of milk produced/day from a lactating goat was estimated to be 0.2 liters. The overall mean litter size, age at first kidding and kidding interval were 2.35 0.59, 13.01 0.96 months and 7.44 0.76 months, respectively. Based on the FGDs with knowledgeable farmers and key informants, “litter size varied from parity to parity and increased as age advanced. At first, the litter size in most cases was single, increased to twins in middle age, and then remained constant after fourth and fifth parity”. Feed/land shortages, drought, diseases and parasites, inadequate extension support, predators and water shortages in descending orders were the most important identified problems. Designing sustainable improvement programs calls for understanding the husbandry practices and reproductive performance of goats in the study area.

The study was carried out to evaluate the effect of genotypes and concentrate levels on growth performance and carcass characteristics of Bati, Hararghe highland (HH) and Short eared Somali (SS) goat types found in Ethiopia. A 3 × 2 factorial arrangement (3 genotype × 2 concentrate levels) was used to randomly allocate 36 goats (15.2 ± 0.30 kg initial weight); 12 goats from each genotype with age about 1 year were divided randomly into two groups for a feeding trial of 90 days. The two concentrate levels were L1 and L2, where L1 and L2 are levels fed to animals at the rate of 1 and 1.5 % BW, respectively. Hay was fed ad libitum with 20 % refusal rate. The mean daily dry matter intake of the goats was 520.5 g/day. The intake was about 67 g/day higher for L2 than L1 goats. Consequently, L2 goats had significantly (p < 0.05) higher average daily gain, dressing percentage, primal carcass cuts and total non-carcass fat than those fed L1. Among genotypes, HH goats were found to have higher (p < 0.05) carcass weight, heart girth, neck girth, and carcass cuts (legs and shoulders) than SS goats. However, they were not better in dressing percentage than SS goats. Compared to Bati goats, HH goats had significantly (p < 0.05) wider rib-eye area, heavier ribs/racks weights, and better dressing percentage. Despite smaller body size, the performance of SS goats was comparable to Bati goats. In conclusion, the study indicates the potential of Ethiopian indigenous goats to produce optimum amount of meat when supplemented with concentrate at the rate of 1.5 % body weight.

This study focused on comparing growth traits (body weights at birth, 3-month weaning and 6-month post-weaning) as well as growth curves of Kalahari Red (KR), a newly introduced goat breed in Nigeria and West African Dwarf (WAD) goat semi-intensively managed. Data on growth traits and weekly live weights were collected from 124 kids consisting of 61 KR and 63 WAD goats. The data were subjected to least squares analysis of variance to evaluate the effects of breed, sex, season, birth type and parity. The results showed that KR kids exceeded WAD kids in body weights at birth (2.30±0.06 kg vs 1.56±0.06 kg), 3-month weaning (8.88±0.57 kg vs 3.88±0.20 kg) and 6-month post-weaning (13.97±0.86 kg vs 5.05±0.37 kg). Corresponding pre-weaning average daily gain (ADG) estimates were 84.44±2.44 g and 31.73±1.16 g and post-weaning ADG were 61.88±1.81g and 24.84±1.21 g. Growth patterns of the two breeds were described using four different non-linear models: Brody, Gompertz, Logistic and Von Berta...
