“…In this study, the CR values of (A 0 and B 0 ) and (A 2 and B 1 ) were better and in the excellent category than those of (A 1 and B 2 ), which were still considered unsatisfactory. Boro et al [23] stated that the conception rate using sexing semen reached 45%.…”

Background and Aim: To enhance the reproductive potential and increase productivity and population of cows, spermatozoa sex-sorting technology is required. This study aimed to examine the effect of sexing sperm, separated using a bovine serum albumin (BSA) column with varying incubation durations and centrifugation methods, for successful artificial insemination. Materials and Methods: Six Simmental bulls and 30 cows (n = 30) as the recipients were selected for this study at Balai Pembibitaan Hijauan Pakan Ternak Sembawa Indonesia. The study parameters included sperm motility, viability, plasma membrane integrity, and conception rate (CR). The experiment was divided into three protocols to find out differences in some parameters: (1) BSA incubation time effect (P) with P1 (40 min), P2 (50 min), and P3 (60 min); (2) freezing time effect with before freezing and after-thawing treatments; and (3) CR determined by measuring the proportion of pregnant cows following insemination with non-sexed, X-bearing, and Y-bearing sperms without centrifugation (n = 15) (A0, A1, and A2) and with centrifugation (n = 15) (B0, B1, and B2) in the acquired data, which were counted using the Statistical Package for the Social Sciences version 21 program. Analysis of variance was utilized to evaluate all treatments at various levels. Results: The results demonstrated that centrifugation time influenced all sperm quality metrics for sperm containing X and Y (p < 0.05). The non-return rate (NRR) of non-sexed frozen semen, both centrifuged (A0) and not centrifuged (B0), was more significant than frozen semen produced by sexing X and Y spermatozoa. The NRR indicated a value of 80% based on the number of lactating cows. Conclusion: Bovine serum albumin incubation and centrifugation protocols influenced and decreased all sperm quality indicators throughout the sexing procedure and could still be used as a sexing protocol. Furthermore, regarding NRR and service per conception, non-sexual treatment is superior to sexing treatment. Keywords: bovine serum albumin, centrifugated, conception rate, incubation, sexing, sperm.

“…Only few references were available which grouped them into some population like Desi pigs of North India, Ankamali pigs of peninsular India, Gahuri pigs of Assam and Ghoongroo pigs of West Bengal (Bhat et al 1981, Bhat et al 2010). However, new population have been characterized and documented (Boro et al 2016a). Some of them have been found to be distinct and are registered by ICAR-NBAGR as new breeds of indigenous pigs.…”

In India, the indigenous pigs are traditionally reared either by the poor, weaker and the tribal sections of the society. Although, the growth rates and feed conversion ratio of indigenous pigs are less than those of exotic or crossbred pigs, they have unique features like heat tolerance, disease resistance, early sexual maturity and ability to produce meat with less fat. In India, the total population of indigenous pigs is 78.35 lakhs constituting 76.14% of the total pig population of the country. Uttar Pradesh has the largest population of indigenous pigs (11.52 lakhs), followed by Assam (10.22 lakhs), Jharkhand (9.21 lakhs) and Bihar (6.26 lakhs). In studies conducted at various centres of All India Coordinated Research Project on pigs, the weight of these pigs at birth, weaning (8 weeks) and 32 weeks of age ranged from 0.44±0.01 to 0.83±0.01, 7.00±0.36 to 8.12±0.18 and 31.32±0.45 to 42.91±1.04 kg, respectively. Although, the indigenous pigs were largely clubbed as local or non-descript but in the last few years many population have been characterized. Some of them have been registered by ICAR-NBAGR as new breeds of indigenous pigs, like Ghoongroo, Niang Megha, Agondagoan, Tenyi Vo, Nicobari, Doom, Zovawk and Gurrah pigs. This review discusses the population trend, attributes and available breeds of indigenous pigs of India.

“…Mishra et al (2009) reported that A1 allele had never been encountered in the eight buffalo breeds raised in India. In other words, A1 beta casein variant is generally found in European originated pure breeds or crossbreeds, and A2 beta casein variant is found in the native cattle and buffalo breeds of India and African domestic cattle (Ng-Kwai-Hang & Grosclaude, 2003;Boro et al 2016).…”

Milk proteins are generally composed of proteins such as casein, lactalbumin, lactoglobulin, blood serum albumin, and immunoglobulin. One of them, casein from milk proteins consists of fractions such as alpha, beta, kappa and gamma. Beta casein gene in cattle consists of 209 amino acids and contains proline amino acid (CCT) at 67 th position of the amino acid sequence. The milk obtained from animals with this genotype is defined as the original A2 milk. Proline/Histidine amino acid substitution (C/A) at 67 th position of the amino acid sequence results in the beta-casomorphin-7 (BCM-7) which is a naturally occurring opioid peptide from cow's milk. By this substitution (CAT), the milk obtained from animals with genotypes (A1A1 or A1A2) is defined as the A1 milk. BCM-7 is a polypeptide consisting of 7 amino acids and is produced from A1 milk during digestion of beta-casein protein. As a result, BCM-7 has harmful effects on human health. The aim of this study is to raise awareness in the field of animal science as well as to contribute to the taking of professional measures by using the literature on A1 / A2 milk and beta-casomorphin-7.
