Comparative performance of Ghungroo and Large Black pig at organized institutional farm conditions

Abstract

Present study was conducted to compare the production and reproduction performance of Ghungroo and Large Black breeds maintained at ICAR Research Complex for North Eastern Hill Region, Nagaland Centre, Jharnapani, Nagaland. The birth weight (1.09 vs. 0.96 kg), pre-weaning growth rate (174.90 vs. 141.40 g/day) and matured body weight at 7 months (64.74 kg vs. 53.13 kg) were significantly higher (p<0.05) in Large Black gilts as compared to Ghungroo. However, the age at first estrus (209.70 vs. 244.42 days) and conception (237.44 vs. 260.81 days) was significantly lower in Ghungroo than Large Black. The litter size at birth (10.24 vs. 8.38) was significantly higher in Ghungroo than Large Black however, similar pattern in litter size at weaning (7.64 vs. 7.20), litter weight at birth (9.28 vs. 9.96 kg) and weaning (47.35 vs. 52.50 kg) were recorded in Ghungroo and Large Black, respectively. The pre-weaning mortality was higher in Ghungroo (2.64) due to lower birth weight and larger litter compared to the Large Black (1.47, p<0.01). Parity wise comparison of major reproductive traits revealed that litter size at birth and pre-weaning mortality were influenced by breed as well as parity, whereas the individual weight at birth and weaning were only influenced by breed not by parities. Thus, from this study it is concluded that the Ghungroo breed matured early, produce more litter and performs similar to the popular Large Black breed under organized farm condition.

Farmers Perceptions on Artificial Insemination (AI): A Mixed Method Design

“…The adoption of breeding technology is also affected and influence by educational level and age of the farmers (Khanal & Gillespie, 2011), in which the findings of our study confirmed this finding as well. Several studies also confirmed that there are several factors that influence the adoptability of AI breeding technology and most of these factors are the level of education of the farmers, family size, distance to AI station and occupation in agriculture or animal husbandry (Mushonga et al, 2017;Patra et al, 2014). Similarly, the findings of this study also confirmed that educational attainment is positively and significantly influence to the farmers perceptions towards AI such as awareness, acceptability, status and prospects.…”

“…A cross-sectional descriptive survey employing a mixed-method design of a qualitative-quantitative methodological triangulation was used to determine the sociodemographic information, and perceptions of farmers about AI in relation to its application in cattle production. The design employed a pragmatic approach through the complementarity of the findings from survey, interviews and focus group discussions to permit the breadth and depth of understanding about the subject matter and enable data collection within a short period (Patra et al, 2014;Ybañez et al, 2017).…”

“…Other researchers also claimed that artificial insemination (AI) has several advantages not only in pigs but also to other livestock compared to natural breeding due to its efficiency, effectiveness in introducing of improved germplasm and control of venereal diseases (Knox, 2016;Maes et al, 2008;Sharma et al, 2021). AI has the potential to enhance the traditional backyard livestock production system particularly among pigs (Kadirvel et al, 2012;Palinkas et al, 2015;Patra et al, 2014). Among various dairy innovations in India, artificial insemination (AI) has been considered as an important dairy innovation of socio-economic importance in Indian dairy industry (Rathod et al, 2017).…”

Effect of Lighting Regimens and Dietary Iodine Sources on Productive and Reproductive Performance for Mandarah Chicken Strain

“…Also, the increase of chicks weight at hatch could due to that organic iodine easily transferred to egg and improve the transport and absorption of minerals (Xiao et al,2015) and regulate the metabolism of embryo (Davis et al, 2000). Similar results were reported by Patra et al (2016) who mentioned that the size of egg had a significant effect on chicks ̛ weight at hatch. The observed increase of relative weight of fabricious gland for chicks of organic iodine group compared with those of inorganic iodine might due to that organic iodine transferred easily to egg, then to embryo and take advantage of alternative absorption routes, provides protection towards mineral antagonisms, against indigestible complexes formation and can elevated immunological function compared to inorganic iodine (Saripinar-Aksu et al, 2012).…”
