Effect of Sex Sorted Semen in Synchronized Estrus on Pregnancy Rate and Female Ratio in Gir Cows

Abstract

Background: At present there is huge demand for Gir cow females however, prolonged inter calving period, more inseminations per conception and post-partum anestrus are the predominant reproductive disorder along with use of unsexed semen limit the birth of more females in Gir cows. The present research study was conducted to study the effect of sex sorted semen in synchronized estrus with Ovsynch protocol on pregnancy rate and gender ratio in Gir cows. Methods: Total twenty Gir cows that have completed post-partum period of sixty days with normal reproductive genitalia, without clinical as well as subclinical infection were selected and divided into two equal groups. The cows from both the groups were synchronized with Ovsynch protocol. In Group- I (n=10), the cows were inseminated with sex sorted semen while in Group-II, the cows were inseminated with coneventional semen. The pregnancy rate and gender ratio was recorded. Result: Efficacy of estrus synchronization was 100.00 per cent for Gir cows treated by Ovsynch protocol in both groups. The pregnancy rate was numerically lower after AI with sex sorted semen (40%) than conventional semen (50%) and results are non significant (P less than 0.05) with 100% calving rate. The proportion of female calves born from sex sorted semen AI was 75% and from conventional semen was 60%. The proportion of live calves born from sex sorted and conventional semen AI was 100%. The sex sorted semen may be used in Ovsynch protocol in Gir cows.

Efficacy of Second Prostaglandin F2 Alpha Treatment during Ovsynch Protocol on Pregnancy Rate Inseminated with Sex-sorted Semen in Buffaloes

“…The results are non-significant (p<0.05) between the groups (Table 1). The pregnancy rate for sex-sorted semen in Ovsynch synchronization was in harmony with results reported by Shinde et al (2022) as 40% pregnancy rate in sex-sorted and 50% in conventional groups treated with Ovsynch synchronization protocol in Gir cows. Carvalho et al (2015) reported 32% and 37% pregnancy rates per artificial insemination (P/AI) in Ovsynch and double PG and reported cows treated with double PGF2á injections with lower P4 concentration on the day of TAI had better reproductive outcomes.…”

Social entrepreneurship and cow tourism: exploring the new vistas of experiential economy

“…2.6.3 Panchagavya for human use. Panchagavya is a combination of five cow products (urine, milk, ghee, curd and dung) which are beneficial for humans (Shinde et al, 2021). Different formulations are used to treat various human diseases such as skin diseases, cough and cold.…”

“…The treatment of human diseases using panchagavya is popularly known as cowpathy or panchagavya chikitsa or therapy. Panchagavya therapy is also recommended as a prophylactic measure (Dhama et al , 2005; Shinde et al , 2021). Naresh et al (2018) experimented on rats by feeding them pomegranate dipped in panchagavya which resulted in enhanced rat immunity, hence deriving that panchagavya also acts as an immunity booster.…”
